Ehmry - 200d82b4f5 core: simplify unprefixed LOG service
The special "platform" label is now "unlabeled".
2020-01-29 12:29:36 +01:00
Ehmry - 5d4e72c874 core: add platform logging service
If the root child requests a LOG service with the label "platform" then
return a LOG session that logs messages directly to kernel. This is to
allow a remote test controller to recognize messages produced by an
privileged local test harness.

Norman Feske 4622ddb46f nitpicker: add version attribute in clicked report
This patch addresses a corner case where the nitpicker focus is not
solely defined by mouse clicks or (exclusively) by a window manager, but
by a policy component that takes mouse clicks and other policy (e.g.,
a lock screen) into account. It ensures that each click that follows a
focus change (however initiated) results in a new "clicked" report even
when the report looks the same. To allow the policy component to
uniquely distiguish subsequent reports, the report features a new
'version' attribute.

This patch let the VFS server reflect the session policy via the
writeable bit in directory entries instead of merely forwarding the bit
from the respective VFS plugin. This way, all files originating from a
read-only file-system session automatically appear in directory listings
as read-only files.

Norman Feske eb9a9bf23d bash.run: support using pipes 2019-11-19 14:54:13 +01:00
Ehmry - c51b4b5742 New VFS plugin for emulating POSIX pipes
Add a new plugin for creating pipes between pairs of VFS handles. It is
intended to replace the libc_pipe plugin, one of the last remaining libc
plugins.

In contrast to the libc_pipe plugin, this plugin defers cross-handle
notification until I/O signal handling rather than block and unblock
readers using a semaphore. This is a performance regression in the case
of multiple threads blocking on a pipe, but shall be an intermediate
mechanism pending renovations within the libc VFS and threading layers.
As a side effect, threads blocked on a pipe might not be resumed until
the main thread suspends and dispatches I/O signals.

The "test-libc_pipe" test has been adjusted to use the VFS pipe plugin
and tests both local pipes and pipes hosted remotely in the VFS server.

Merge adaptations (such as EOF handling, adjustment to VFS/libc
interface changes) by Norman Feske.

Fix #2303
2019-11-19 14:54:13 +01:00
Norman Feske 9b7915facb vfs server: redesigned internal control flow
This patch reworks the VFS server to become easier to understand.

- The packet-stream handling is hidden from the node types.

- Introduced the notion of a "job" as an abstraction from the raw packet
  stream.

- The processing of requests is split into three phases:
  (1) accepting new jobs,
  (2) the execution of jobs, and
  (3) the delivery of acknowledgements.

- There is no longer a global fifo of pending nodes. Instead, each
  session has a fifo of "active" nodes, which are nodes that wait
  for the completion of jobs.

- The Io_node type no longer uses virtual functions as hooks for
  the derrived classes. Instead, it provides a number of utility
  functions.

- The control flow of the 'Io_progress_handler' is now the same as
  for the session-local packet-stream handler.

- Removed dependency from 'file_system/node.h', which is a relic
  from the ram_fs.

While reworking the code, the following semantic changes were made
additionally.

- The handling of SEEK_TAIL no longer overwrites the file content at the
  end of the file.

- Removed diagnostic message at session-creation time.

- Write loop for continuous files

Norman Feske fab2fc874f libc: write loop for continuous files
This patch improves the libc's write operation to iterate on partial
writes to continuous files until the original write count is reached.
The split of large write operations into small partial writes as
dictated by the VFS infrastructure (e.g., constained by I/O buffer
sizes) becomes invisible to the libc-using application.

This patch equips the VFS terminal file system with the ability to
detect user interrupts in the incoming data stream, and propagate this
information via the new pseudo file '.terminal/interrupts'. Each time,
the user presses control-c in the terminal, the value stored in this
pseudo file is increased. Thereby, a VFS client can watch this file to
get notified about the occurrences of user interrupts.

Martin Stein 0ad0153626 nic_router: fix broken uplink label on re-config
Uplink labels were stored in the uplink objects as reference. As uplink objects
may be re-used on re-configuration to avoid unnecessary closing and re-opening
of NIC sessions, the label reference could get invalid as the object that
stored the label content didn't get re-used. Thus, the label is now copied to
the uplink object.

Martin Stein 60d37f690c packet_stream_*: fix missing dissolve on exception
When the construction of a member of Packet_stream_*::Rpc_object after
the _cap member threw an exception, the object was not dissolved from
the entrypoint although the Rpc_object vanished at this point. This was
because the call to 'manage()' happened in the initializer list (for the
_cap member instantiation). The destruction of the _cap member then did
not dissolve the object.

This first fix moves the call to 'manage()' into the constructor body
after the instantiation of all other members. A more sophisticated fix
would use some kind of 'Managed_object' life-time guard that manages an
object on construction and dissolves on destruction.

Norman Feske 7ac32ea60c libc: support for ioctls via ioctl directory
This patch introduces a new scheme of handling ioctl operations that
maps ioctls to pseudo-file accesses, similar to how the libc maps socket
calls to socket-fs operations.

A device file can be accompanied with a (hidden) directory that is named
after the device file and hosts pseudo files for triggering the various
device operations. For example, for accessing a terminal, the directory
structure looks like this:

  /dev/terminal
  /dev/.terminal/info

The 'info' file contains device information in XML format. The type of
the XML node corresponds to the device type. E.g., If the libc receives
a 'TIOCGWINSZ' ioctl for /dev/terminal, it reads the content of
/dev/.terminal/info to obtain the terminal-size information. In this
case, the 'info' file looks as follows:

  <terminal rows="25" columns="80/>

Following this scheme, VFS plugins can support ioctl operations by
providing an ioctl directory in addition to the actual device file.

Internally, the mechanism uses the 'os/vfs.h' API to access pseudo
files. Hence, we need to propagate the Vfs::Env to 'vfs_plugin.cc' to
create an instance of a 'Directory' for the root for the VFS.

Norman Feske 5ab1505d43 file system: enhanced file status info
This patch extends the 'File_system::Status',
'File_system::Directory_entry', and the related 'Vfs' types with
the following additional information:

- Distinction between continuous and transactional files (Node_type)
  (issue #3507)
- Readable, writeable, and executable attributes (Node_rwx),
  replacing the former 'mode' bits
  (issue #3030)

The types 'Node_rwx', 'Node_type' are defined twice,
once for the VFS (vfs/types.h) and once for the 'File_system'
session (file_system_session/file_system_session.h).
Similarly, there is a direct correspondance between
'Vfs::Directory_service::Dirent' and 'File_system::Directory_entry'.

This duplication of types follows the existing pattern of keeping the
VFS and file-system session independent from each other.

Norman Feske eefe91ee41 depot_download_manager: no mtime update in extract
With the added modification-time support in the libc, the extract tool
requires a timer session, which is not plausible for the purpose of the
program.

This behavior stems from the fact that the libc implicitly writes the
mtime when closing a written file. For this update, it implicitly calls
'clock_gettime', which in turn initializes the timer subsystem within
the libc (creating a timer session).

For the extract tool, the implicitly updated mtime is useless because
the extract tool overwrites this modification time with the mtime stored
in the archive anyway. However, the dependency from a timer service
remains.

This patch explicitly disables the libc's implicit updating of the
file-modification when closing a written file.

Josef Söntgen 94b63924ed noux: add time modification
... and set initial time by using RTC session.

Up to now Noux used a monotic clock whose initial start value always
was '0' (which correlates to the start of the UNIX epoch) to provide
a notion of time. In addition it is now possible to use the RTC
session to set the initial value for use cases where having a proper
real-world time matters.

To use the RTC session the 'rtc' attribute of the '<config>' node
must be set to 'yes'. Thereby the session becomes a mandatory
dependency as Noux will not start without it.

This patch replaces the naive dup2 implementation (that merely

position. This prevents a potential double release of the VFS handle
(the FD context). It also implements 'dup'.

Norman Feske 648bcd1505 libc: unify use of namespaces
This patch unifies the patterns of using the 'Genode' and 'Libc'
namespaces.

Types defined in the 'internal/' headers reside in the 'Libc'
namespace. The code in the headers does not need to use the
'Libc::' prefix.

Compilation units import the 'Libc' namespace after the definition of
local types. Local types reside in the 'Libc' namespace (and should
eventually move to an 'internal/' header).

Since the 'Libc' namespace imports the 'Genode' namespace, there is
no need to use the 'Genode::' prefix. Consequently, code in the
compilation units rarely need to qualify the 'Genode' or 'Libc'
namespaces.

There are a few cases where the 'Libc', the 'Genode', and the global
(libc) namespaces are ambigious. In these cases, an explicit
clarification is needed:

- 'Genode::Allocator' differs from 'Libc::Allocator'.
- 'Genode::Env' differs from 'Libc::Env'.
- Genode's string functions (strcmp, memcpy, strcpy) conflict
  with the names of the (global) libc functions.
- There exist both 'Genode::uint64_t' and the libc'c 'uint64_t'.

Norman Feske bf92232698 libc: split task.cc into multiple files
This patch is the first step of re-organizing the internal structure of
the libc. The original version involved many direct calls of global
functions (often with side effects) across compilation units, which
made the control flow (e.g., the initialization sequence) hard to
follow.

The new version replaces those ad-hoc interactions with dedicated
interfaces (like suspend.h, resume.h, select.h, current_time.h). The
underlying facilities are provided by the central Libc::Kernel and
selectively propagated to the various compilation units. The latter is
done by a sequence of 'init_*' calls, which eventually will be replaced
by constructor calls.

The addition of new headers increases the chance for name clashes with
existing (public) headers. To disambiguate libc-internal header files
from public headers, this patch moves the former into a new 'internal/'
subdirectory. This makes the include directives easier to follow and the
libc's source-tree structure more tidy.

There are still a few legacies left, which cannot easily be removed
right now (e.g., because noux relies on them). However, the patch moves
those bad apples to legacy.h and legacy.cc, which highlights the
deprecation of those functions.

Norman Feske 23f3112e3e ports: bash.run script using the libc fork/execve
Issue #3481
2019-08-28 14:19:45 +02:00
Norman Feske 6894ced63b libc: execve
This patch implements 'execve' in Genode's libc.

The mechanism relies on the dynamic linker's ability to replace the
loaded binary while keeping crucial libraries - in particular the libc -
intact. The state outside the libc is wiped. For this reason, all libc
internal state needed beyond the 'execve' call must be allocated on a
heap separate from the application-owned malloc heap. E.g.,
libc-internal file-descriptor objects must not be allocated or refer to
any memory object allocated from the malloc heap.

Norman Feske 66d5359d75 ldso: heuristics for libs needed during execve
The allocation of regions within the linker area is normally left to the
best-fit 'Allocator_avl', which happens to populate the linker area
starting with the binary followed by all loaded libraried with no gaps
in between.

When replacing the binary during execve, however, we need to ensure that
the new binary does not conflict with any library that stays resident
during execve. This patch tweaks the linker's region allocation scheme
such that these libraries are placed at the end of the linker area.

Issue #3481
2019-08-28 14:18:45 +02:00
Norman Feske fa48054959 ldso: Dynamic_linker::respawn mechanism
This patch extends the interface of the dynamic linker with the ability
to replace the running binary executable by another one. It is
designated for the implementation of execve. The interface consists of
two new functions.

'Dynamic_linker::keep' marks the specified shared object as unloadable.
This can be used to pin a set of libraries (i.e., the libc) within the
local address space while replacing the binary and other higher-level
libraries.

'Dynamic_linker::respawn' unloads the current binary, loads the one
specifed as first argument, and looks up the entry point symbol of the
new binary, which would be "main" for POSIX programs.

In addition to implementing the new interface, the patch adjusts the
linker at various places that previously assumed the binary to be
constant over runtime.

Norman Feske 3c6fe6e741 ldso: statically allocate initial heap block
This patch enables the fork.run script to run on base-linux. It should
be regarded as an interim solution, however, because the randomization
performed by the Linux kernel may still - by chance - produce a
situation where one of the libc's malloc heap regions intersects with
another dataspace dynamically attached to the child.

The better solution would be to make the 'Region_map_mmap'
implementation not depend on the kernel's allocation policy by using a
locally implemented allocator.

Norman Feske 581785a48f Extend fork test
This patch extends the fork test with explicit checks for the cloned
content of the heap and RW segment as well as the seek position of an
open file descriptor. It adds the new libports/run/fork.run script
that exercises the fork mechanism implemented by the libc. It is based
on noux_fork.run, which tests the mechansim provided by noux. The
test program has been moved from ports to libports.

Norman Feske 65f75589e9 libc: configurable initial FDs
The libc already supports the configuration of 'stdin', 'stdout', and
'stderr' using '<libc>' config attributes. This patch equips the libc
with the additional ability to pre-initialize any other file descriptor.
A file descriptor is configured as follows:

<config>
  ...
  <libc ...>
    <fd id="3" path="/dev/log" writeable="yes" readable="no" seek="10"/>
    ...
  </libc>
</config>

Furthermore, this patch moves the FD initialization code from the VFS
plugin to the libc kernel initialization because opening the FDs
depends on 'malloc' ('strdup'), which should not be used at early
'Libc::Kernel' initialization time.

Norman Feske 6e38b53001 libc: use Id_space for FD allocator
This patch replaces the former use of an Allocator_avl with the Id_space

implementing 'fork'.

Norman Feske e499a04de7 ldso: config option to disarm ctors check
By specifying the config attribute 'check_ctors="no"', the dynamic
linker won't abort the program on a missing call of
'Env::exec_static_constructors'. This is the case for forked programs
where the ctors were already executed by the forking program prior the
fork operation.

Norman Feske abdf422681 ldso: interface to get infos about loaded objects
This patch enhances the 'base/shared_object.h' interface of the dynamic

caller to obtain information about the currently loaded binary and
shared libraries.

The new interface is a base mechanism needed for implementing 'fork' in
the libc.

Prior this patch, the 'transfer_quota' operation would trigger an
'Out_of_caps' exception.

This patch handles the situation where the usb_block_drv exits for any
reason, in particular when the driver fails to initialize the device. In
such cases, the usb_block_drv used to stay stale in the system,
effectively preventing the device from being passed to a VM. With the
patch, the USB storage device gets flagged as failed, the usb_block_drv
is removed from the runtime, and the condition is reflected at the user
interface.

This situation occurred on the attempt to access an iomega zip drive
with a version of the usb_block_drv without support for the START-STOP
command, but it may potentially also occur in other circumstances.

Christian Helmuth ce149397ec acpica: retrieve static battery info only once
On Fujitsu S936, evaluating the _BIF method on each battery-info update
successively increased the RAM usage, while  _BST (dynamic battery
status) and _STA (generic status) did not show this behavior. Therefore
this commit retrieves only dynamic information periodically (resp. on
SCI IRQ). Now, acpica hast static RAM usage in idle state for 24+ hours.

The root cause for the increased RAM usage is still shady. While it
could just be normal that it grows until a certain yet unknown limit,
there may also be memory leak in contrib code or some strange AML on the
designated notebook.

Norman Feske 7e7eff0eb7 window layouter: reduce snap-back artifact
When resizing windows of clients that respond very slowly to resize
requests, the window's size sometimes snapped back to its original size
immediately after finishing the drag operation.

The problem was caused by the interplay of the layout rules (obtained
via the 'rules' ROM, generated by the 'rules' report) and the
temporary interactive state that occurs during drag operations.
The rules are updated only at the time of releasing the button to keep
the overhead while dragging the window low. However, when releasing the
mouse, the (now outdated) rules kicked back into effect, triggering
resize requests for the window to its old size.

The patch solves this problem by decoupling the dragged state of a
window from the physical release of the button. The button release
triggers a transition from a DRAGGING to a SETTLING state and programs
a timer. In the SETTLING state, the windows behave as in DRAGGING state,
giving the interactive geometry precedence over the rules-dictated
geometry. During this state, further responses of window-resize requests
may come in and are handled like dragging was still in progress. After a
timeout, however, the current window layout is conserved as a new rules
report and the state goes back to IDLE.

For clients that takes a very long time (in particular, VirtualBox when
resizing the desktop, which takes sometimes multiple seconds), the
snap-back artifact can still occur, but the effect is reduced.

Norman Feske dec2d897c3 themed_decorator: fix jumping windows
The decorator's detection of the hovered window element was inaccurate,
which resulted in "jumping" windows in some situations, ultimately
caused by a combination of three different mechanisms.

First, when moving the pointer into the area of a window, the decorator
would detect the hovering of the left border whenever the distance of
the pointer from the border was less than the half of the theme texture
(e.g., 64x64 pixels for the default theme). However, if the left border
margin is set to a small value (e.g., 1), there is an overlap of the
sensitive resize border area and the content. Hence, chances were quite
high that - when moving the pointer from the left into the window - the
hover report would contain the hovering of the left border.

Second, the window manager tries to hide pointer movements from the
decorator if possible. It informs the decorator of the pointer position
if any decoration is hovered or if a new window is hovered. But it does
not expose pointer movements within a window to the decorator. For this
reason, the decorator would not update the hover report as long as the
pointer stays within a once hovered window. In the situation described
above, the hover report would still contain the stale information about
the hovering of the left resize border.

Third, when the user clicks on the window, the decorator examines the
most recent hover report and - in the situation described above - finds
the left border hovered. Consequently, it initiates a window-drag
operation. While resizing the window with the left border, the window
layouter pins the right border of the window to its current position.
All window-size changes of the client will be applied towards the left
(dragged) border. In the case of the top view, which continuously
resizes the window by itself, the window would "jump". In reality, it
actually tries to respond an interactive resize operation. The window
layouter cannot guess that the client is not responding to window
layouter's resize request but is acting independently.

This patch fixes the jumping window problem for the case where the
pointer hovers the overlapping area of the resize border and the
content. However, when trying the to interactively resize the top window
via the bottom-left corner, the "jumping" can still be observed.

Martin Stein 5a59d295a4 depot_autopilot.run: relax test timeout
There are still nightly tests like test-tcp_bulk_lxip on sel4 x86_64 qemu
that manage to hit the test timeout of the run script although the test was
successful. So, raise the extra time added by the run script to 30 seconds.

Martin Stein fe5ada85cb depot_autopilot.run: max nr of tests per boot
Some platforms (sel4 imx6/imx7) cannot manage to execute all tests in a single
boot. Thus, we re-boot them periodically after a given maximum number of tests
to avoid that arbitrary tests always fail due to the long uptime and not due to
the tests themselves.

If the maximum number of tests is set to 0, no limit is applied.

Christian Prochaska 62232f9a35 fs_rom: retry watching a path element after watching its parent dir
If a path element cannot be watched because it does not exist yet, the next
available parent directory is watched to detect the creation of the missing
path element. If a missing path element got created just between the failed
watch request for the element and the successful watch request for its parent
directory, the creation of the path element could remain unnoticed.

With this commit, 'fs_rom' tries to watch a path element again if the watch
request for its parent directory was successful.

timeout ratio from 50/25 ms to 200/25 ms and set the test runtime to
4000 ms.

switching becomes a no go for base-hw because we cannot avoid FPU
instructions because of the entanglement of base-hw, base, and the tool

Josef Söntgen d223539165 wifi_drv: ignore socket flags on socket creation
The libc features support for SOCK_CLOEXEC now which gets set via

actual type, i.e. if it is SOCK_RAW, just ignore the flags.

Stefan Kalkowski a1e70b9ba4 kernel: differentiate board-specific components
Components like kernel, core, and bootstrap that are built for a
specific board need to reside inside the same architectural dependent
build directory. For instance there are sel4, foc, and hw kernel builds
for imx6q_sabrelite and imx7d_sabre, which have to reside inside the same
arm_v7 build directory.
This commit names those components explicitely, and adapts the run-tool to it.

device that triggered the report buffer overflow. This commit fixes the
issue by putting the BDF counter initialization inside the lambda

Norman Feske 784206c85c block_session: new client-side API
This patch equips the 'Block::Connection' with a framework API for the
implementation of robust block-session clients that perform block I/O in
an asynchronous fashion.

An application-defined 'JOB' type, inherited from 'Connection::Job',
encapsulates the application's context information associated with a
block operation.

The lifecycle of the jobs is implemented by the 'Connection' and driven
by the application's invokation of 'Connection::update_jobs'. The
'update_jobs' mechanism takes three hook functions as arguments, which
implement the applications-defined policy for producing and consuming
data, and for the completion of jobs.

Norman Feske 593e971121 block_session: SYNC and TRIM as async operations
This patch removes the blocking Block::Session::sync RPC function and
adds the asynchronous operations SYNC and TRIM to the block session's
packet-stream interface.

Even though the patch adjusts all block components to the interface
change, the components keep the former blocking handling of sync
internally for now because of the design of the 'Block::Driver'
interface. This old interface is not worth changing. We should instead
migrate the block servers step by step to the new
'Block::Request_stream' API.

Norman Feske e058adc4fe block_session: add client-defined request tag
The new request tag allows a block-session client to uniquely correlate
acknowledgements with outstanding requests. Until now, this was possible
for read and write operations by taking the value of the request's
packet-stream offset. However, SYNC and TRIM requests do not carry any
packet-stream payload and thereby lack meaningful offset values. By
introducing the notion of a 'tag', we can support multiple outstanding
requests of any type and don't need to overload the meaning of the
'offset' value.

Norman Feske a39474a245 block-request stream: split Operation from Request
This patch splits the 'Request' definition into smaller types that are
suitable for the client-side API too.

The new 'Operation' type comprises the block operation's type (opcode)
and the operation's arguments (block number, block count).
The former 'Request::operation_defined' is now 'Operation::valid'.
The 'Request' aggregates an 'Operation', which changes its object
layout.

Note that this commit relaxes the bit-precise definition of 'Request' to
facilitate the use of 'unsigned long' where appropriate, in particular
for the request tag (which should correspond to an 'Id_space::Id'). The
originally bit-precise definition was pursued to allow the sharing of
the 'Request' type between SPARK and C++ code. However, it turns out
that defining a native type in each language and a (set of) converting
constructors is a more natural approach.

Norman Feske bbe3ee8dc5 block_session: server-defined payload alignment
This patch replaces the formerly fixed 2 KiB data alignment within the
packet-stream buffer by a server-defined alignment. This has two
benefits.

First, when using block servers that provide small block sizes like 512
bytes, we avoid fragmenting the packet-stream buffer, which occurs when
aligning 512-byte requests at 2 KiB boundaries. This reduces meta data
costs for the packet-stream allocator and also allows fitting more
requests into the buffer.

Second, block drivers with alignment constraints dictated by the
hardware can now pass those constraints to the client, thereby easing
the use of zero-copy DMA directly into the packet stream.

The alignment is determined by the Block::Session_client at construction
time and applied by the Block::Session_client::alloc_packet method.
Block-session clients should always use this method, not the 'alloc_packet'
method of the packet stream (tx source) directly. The latter merely
applies a default alignment of 2 KiB.

At the server side, the alignment is automatically checked by
block/component.h (old API) and block/request_stream.h (new API).

Norman Feske 4b0b4928f5 tool/depot: rm binary archives if versions collide
This patch handles version collisions of binary archives. If a binary
archive for an (automatically) updated src-archive version already
exists in the depot, the extract tool removes the binary archive because
its existing content may stem from another src content (a version from a
different topic branch). This ensures that the new version is always
built, not skipped, when 'UPDATE_VERSIONS=1 REBUILD=' is specified.

Norman Feske aeb7e7cd7c sculpt manager: prevent double destruction
The '_currently_constructed' pointer caches the information about which
'Launched_child' is currently configured in the menu. When discarding
the runtime (e.g., when un-using a file system) at this point, this
cached pointer was not invalidated while all 'Launched_child' objects
would be freed (including the currently constructed one). On the next
attempt to construct a new child, the sculpt manager attempted to
destruct the 'Launched_child' referred by the (now outdated)
'_currently_constructed' again.

Norman Feske 806dc5de36 window layouter: improved maximize handling
It turns out that the commit "window layouter: allow floating apps to
resize" interplays badly with the interactive toggling of the maximize
state of windows. In contrast to the window geometry and stacking, which
is always updated through the rules-feedback mechanism, interactive
changes of the maximize state omitted this loop and instead took a local
shortcut. Because of this shortcut, the maximized geometry eventually
ended up as window size in the window's assign rule. So unmaximizing the
window failed to revert the geometry to its original state.

This patch removes this inconsistency. The maximize state adheres to the
official chain of commands through the rules mechanism now. The state is
now maintained internally without affecting the window's geometry and is
evaluated while generating the window layout only.

As a minor loosely related improvement, this patch prevents the
highlighting of resize handles for non-resizable windows.

first layout update is applied. By explicitly initializing the
'_geometry' to (0x0+0+0), we avoid this initial artifact.

Norman Feske 669aed0ac0 sculpt: don't reset hover on click on '+' menu
When entering/leaving sub menus of Sculpt's '+' menu, some parts of the
menu sometimes remain unchanged, in particular the back button.
Originally, a click would reset the hovering on clicks in the
expectation that any click would eventually result in a completely new
situation where the old hovering information does not make sense and
would only (potentially) confuse the menu. But this was apparently
overzealous. With the patch a once hovered back button stays hovered
even when actitivated and the back button of the upper-level menu
happens to stay under the current pointer position.

Norman Feske 014e800e8a menu view: immediate hover update on dialog change
This patch improves the hover handling in situations where the dialog
changes under the pointer. Previously, hover changes were reported
as response to user input only, which failed to cover this case. This
became a problem with Sculpt CE's '+' menu, which changes on the fly
when entering/leaving sub menus.

The patch also cleanly separates the hover handling from the focus
handling. Originally, the hovering was reset when the menu view got
unfocused. In situations like Sculpt's '+' menu where the menu view
receives a transient focus only while clicked and gets unfocused on the
button-release event (aka clack), each clack would invalidate the hover
information until a new input event comes in.

Finally, the patch introduces the clear distinction between situations
where the entire dialog is hovered or not. Previously, this state was
somehow implicitly kept by issuing an invalid hover report whenever a
leave event was observed.

Norman Feske a61c5b6be3 wm: move virtual pointer pos on window movement
When a window is moved, the virtual pointer position must be updated,
taking the changed input coordinate into account. This patch propagates
such changes via absolute motion events to the client.

Without this patch, Sculpt CE's '+' menu wouldn't update the hovered
item correctly when entering/leaving sub menus (which happen to trigger
the repositioning of the menu on screen).

Ehmry - 57fd4e9148 Add Io_progress_handler to Entrypoint interface
The "schedule_post_signal_hook" method of the Genode::Entrypoint class
is problematic because the signal hook can be scheduled and replaced
multiple times during the signal dispatch cycle. Add an alternative to
this method with "register_io_progress_handler" and the "Post_signal_
hook" class with "Io_progress_handler". The difference being an
"Io_progress_handler" may be registered once during the lifetime of an
entrypoint to prevent arbitrary libraries from replacing a pending hook.

The "register_io_progress_handler" remains as a deprecated API, and is
now invoked for every I/O signal received and only for I/O signals
rather than for any signal.

Norman Feske c41fbe9ea5 sculpt: don't mark in-construction pkgs as present
This patch excludes the current "Construction" from the list of
"present" components in the runtime. Without the patch, a missing "wm"
would go unmissing once when the routing dialog of a new wm instance
appears. Now an already present window layouter that had a broken route
would prematurely re-appear in the config, which should not happen
because the new wm does not exist yet.

signing processes.

Norman Feske cd244c2077 sculpt: don't install any index by default
When buiding the sculpt image, the sculpt.run script used to integrate
the current version of the index of the 'depot_user' into the boot
image. At runtime, when the Sculpt partition is selected for "use" this
index - along with the 'pubkey' and 'download' files of the known
depot users - is written to the Sculpt partition.

This has the undesirable effect that a later version of the index
(published some time after the sculpt image was created) would always be
overwritten by the outdated index shipped with the boot image.

The built-in default index was actually a stop-gap solution needed
during the development of Sculpt CE, introduced when the downloading of
index files was not yet supported. Now, with the working download
mechanism, it is no longer needed. Hence, this patch removes the default
index from the sculpt image.

at Genode Labs embrace either the Ion3 window manager or the tiled Terminator
terminal emulator. Hence, we desire to have a similar mode of user
interaction on Genode as well. The goal of this challenge is to identify the
most important usage patters and the implementation of a tiled GUI that
multiplexes the framebuffer into a set of tiled and tabbed virtual
framebuffers.

:Xlib compatibility:
Developments like Wayland notwithstanding, most application software on
GNU/Linux systems is built on top of the Xlib programming interface.
However, only a few parts of this wide interface are actually used today.
I.e., modern applications generally deal with pixel buffers instead of
relying on graphical drawing primitives of the X protocol. Hence, it seems
feasible to reimplement the most important parts of the Xlib interface to
target Genode's native GUI interfaces (nitpicker) directly. This would
allow us to port popular application software to Sculpt OS without
changing the application code.
:Bump-in-the-wire components for visualizing session interfaces:
Genode's session interfaces bear the potential for monitoring and
visualizing their use by plugging a graphical application
in-between any two components. For example, by intercepting block
requests issued by a block-session client to a block-device driver,
such a bump-in-the-wire component could visualize
the access patterns of a block device. Similar ideas could be pursued for
other session interfaces, like the audio-out (sound visualization) or NIC
session (live visualization of network communication).

e.g., new opportunities for optimization. But more importantly, they
would be extremely fun to play with.

Even though the Linux version of Genode is primarily meant as a development

Linux process containers provide a mechanism to partition physical resources,
foremost CPU time, between Linux processes. This raises the interesting
question of whether this mechanism could be used for a proper implementation
of Genode's resource trading on Linux.
[http://lwn.net/Articles/236038/ - Process containers introduction...]
Even though there exists a great variety of ARM-based SoCs, Genode
primarily focuses on the NXP i.MX family because it is - in contrast
to most SoCs in the consumer space - very liberal in terms of
good-quality public documentation and reference code, and it scales
from industrial to end-user-facing use cases (multi-media).

The project would explore the application of the Puppet approach and tools
to Sculpt OS.
Optimizations

:Low-latency audio streaming:
Genode comes with an audio streaming interface called 'Audio_out' session.
It is based on a shared-memory packet stream accompanied with asynchronous
data-flow signals. For real-time audio processing involving chains of Genode
components, streams of audio data must be carried at low latency, imposing
constraints to buffer sizes and the modes of operation of the audio mixer and
audio drivers. The goal of this project is to create a holistic design of the
whole chain of audio processing, taking thread-scheduling into account. A
particular challenge is the mixed output of real-time (small buffer, low
latency) and non-real-time (larger buffer to compensate jitter, higher
latency) audio sources.

===========
Genode OS Framework release 19.11 | 2019-11-28
##############################################
| Following this year's theme of "bridging worlds", Genode 19.11 adds the
| ability to use popular build tools like CMake for application development,
| introduces a new virtual-machine monitor for 64-bit ARM, and enhances
| POSIX compatibility. As another highlight, it features the first version
| of our custom block-device encrypter.
Block-device encryption is a feature often requested by users of our Sculpt OS.
Until now, we deliberately left this topic unaddressed because we felt that a
profound answer was beyond our expertise. However, during the past year, we
dived deep into it. The result is the prototype for a new block encrypter that
encrypts data but also protects integrity and freshness. For us, the
implementation of the encrypter is especially intriguing because - with about
7000 lines of code - it is Genode's first non-trivial component written in the
[https://en.wikipedia.org/wiki/SPARK_(programming_language) - SPARK]
programming language.
The second major addition is a new virtual machine monitor (VMM) for 64-bit
ARM platforms such as the NXP i.MX8. It leverages the
[https://genode.org/documentation/articles/arm_virtualization - proof of concept]
we developed in 2015 for ARMv7, which we pursued as a technology exploration.
In contrast, our aspiration with the new VMM is a product-quality solution.
In our [https://genode.org/about/road-map - road map] for 2019, we stated
the "bridging of worlds" as our overall theme for this year. On that account,
the current release moves the project forward on two levels. First, by
successively increasing the scope of POSIX compatibility, we reduce the
friction when porting existing application software to Genode. We managed
to bridge several gaps in our POSIX support that we considered as impossible
to cover some years ago. In particular, we identified ways to emulate certain
POSIX signals, ioctl calls, and fork/execve semantics. This way, popular
software such as bash, coreutils, or Vim can now be executed as regular
Genode components with no additional runtime environment (like Noux or a VMM)
required.
At a higher level, the current release introduces new tooling especially
geared at the development and porting of application software. Compared to
Genode's regular development tools, which were designed for whole-system
development, the new tool called Goa relieves the developer from the
complexity of Genode's custom build system and instead promotes the use of
popular commodity solutions like CMake.
These and more topics are described in the
[https:/documentation/release-notes/19.11 - release documentation of version 19.11...]
Genode OS Framework release 19.08 | 2019-08-28
##############################################
| Genode 19.08 puts emphasis on practical concerns ranging from
| keyboard layouts, over system-time management, to remote system
| administration. It also continues our commitment to the 64-bit ARM
| i.MX8 SoC, comes with Qt5 version 5.13, and improves POSIX compatibility.
The summer release of Genode addresses a variety of topics when using Genode
and Sculpt OS in practice. The confrontation with the real world prompted us
to develop new concepts for managing system time, keyboards layouts, and
copy-and-paste. For using Sculpt OS on the road, a new application VM for
accessing captive portals smoothes the experience of connecting to public WiFi
networks.
Besides the practical focus, the new release continues our commitment to the
64-bit ARM i.MX8 platform through new kernel support, device drivers, and test
coverage. Further topics include SMBIOS support for commodity PC hardware, a
new tracing tool, enhanced POSIX compatibility, and a major update of Qt5 to
version 5.13.

Sculpt OS release 19.07 | 2019-07-09
####################################
| Version 19.07 of the Sculpt operating system improves overall performance
| and introduces copy and paste between terminals, virtual machines, and
| graphical applications.
The most prominent user-visible feature of Sculpt OS 19.07 is the ability
of copy and paste text between terminals, graphical applications, and
virtual machines. Our unique take on this feature is described in
a [https://genodians.org/nfeske/2019-07-03-copy-paste - dedicated article].
Under the hood, Sculpt 19.07 benefits from the massive infrastructure
improvements that came with
[https://genode.org/documentation/release-notes/19.05 - Genode 19.05],
yielding a smoother user experience compared to earlier versions.

Genode OS Framework release 19.05 | 2019-05-29
##############################################
| The highlights of version 19.05 are a new kernel-agnostic virtualization
| interface, initial support for the 64-bit ARM architecture, the use of
| C++17 by default, a new tool chain based on GCC 8.3, updated C and SPARK
| runtimes, and the consolidation of build directories across boards.
We dedicated the release cycle of Genode 19.05 to platform topics at various
levels. The flagship feature is certainly the introduction of our
kernel-agnostic virtualization interface. It has been in the works for more
than a half year and gives us the prospect of running virtual machine monitors
like Seoul and VirtualBox seamlessly across Genode's supported kernels.
The second major theme is the extension of Genode's CPU-architecture support
to 64-bit ARM (AARCH64). This step motivated the update of many parts of the
framework's fundamental infrastructure, ranging from the tool chain (updated
to GCC 8.3), over the C runtime (updated to FreeBSD 12 libc), to the dynamic
linker. The new tool chain, in turn, paved the ground for enabling C++17 by
default.
With the diversity of kernels, CPU architectures, and boards growing, we are
constantly striving to remove friction and redundancies between Genode's
underlying platforms. The current release eventually consolidates the build
directories not only across kernels but also across all boards of a given
CPU architecture. This vastly increases the velocity of Genode-based system
scenarios when targeting multiple boards or emulators at the same time.
Further details about these and many more improvements are given in the

only, each revision became more and more user friendly. The previous version
Sculpt VC already offered a glimpse of Sculpt's unique user interface in the
form of an interactive component graph.
The just released Sculpt OS "as a community experience" (CE) combines this
tangible notion of component compositions with a completely federated software
provisioning model that cuts out middlemen like an app store or a
distribution. With Sculpt CE, components can be offered by a federation of
independent software providers selectable by the user. The software
installation is sandboxed and protected via digital signatures. The
integration of components with the rest of the system is completely under
control by the user. With the principle of least privilege at the heart
of Sculpt's architecture, you - the user - can fearlessly install and run
software without the need to ultimately trust the software providers.
Sculpt CE is intended to work in tandem with the new community blog
[https://genodians.org - Genodians.org] where developers and users exchange
experiences and announce new software. The best way to watch how the
Sculpt story continues is the RSS feed of Genodians.org.

===============================================
Release notes for the Genode OS Framework 19.05
===============================================
Genode Labs
The Genode release 19.05 is primarily focused on platform support.
It adds compatibility with the 64-bit ARM architecture (AARCH64),
comes with improvements of the various kernels targeted by the framework,
and extends the list of supported hardware. The increased diversity of base
platforms calls for unifications to keep the hardware and kernel landscape
manageable.
On that account, Genode uses one reference tool chain across all kernels
and CPU architectures. The current release upgrades this tool chain to
*GCC 8.3* with C++17 enabled by default
(Section [Tool chain based on GCC 8.3.0 and binutils 2.32]).
To increase the velocity of Genode system scenarios across different boards
of a given CPU architecture, the release introduces the notion
of *board and kernel-agnostic build directories* presented in Section
[Unified build directories for ARM]. Once built for one particular
CPU architecture, the same binaries can be deployed at any supported board or
kernel without recompilation. This vastly accelerates the workflow when
targeting multiple boards and emulators at once.
As another major unification effort, the current release introduces a new
*kernel-agnostic virtualization* interface. Up until now, virtualization
used to be inherently tied to a specific kernel. Thanks to the new interface,
however, one virtual machine monitor implementation can be combined with
kernels as different as NOVA, seL4, or Fiasco.OC. No recompilation needed.
As outlined in Section [Kernel-agnostic virtual-machine monitors], Genode
has now become able to run the Seoul VMM on all those kernels, while
VirtualBox is planned to follow.
On our [https://genode.org/about/road-map - road map], we originally
planned several user-facing features related to Sculpt OS. However, in the
light of the major platform efforts, we decided to defer those topics instead
of rushing them.
That said, the release is not without new features. For example, our port
of *OpenJDK* has become able to host the Spring framework and the Tomcat web
server, there are welcome improvements of the *package-management tooling*,
and we added new options for user-level networking.
Finally, version 19.05 is accompanied with the annual revision of the *Genode*
*Foundations book* (Section [New revision of the Genode Foundations book]),
which is now available as an online version in addition to the regular PDF
document.
Kernel-agnostic virtual-machine monitors
########################################
Since the introduction of Genode's
[https://genode.org/documentation/release-notes/17.02#Genode_Application_Binary_Interface - Application Binary Interface]
in the 17.02 release,
Genode components can be assembled once for a given hardware platform and
executed without further adjustments on all the supported kernels. However, at
that time, the supported virtual machine monitors - a port of VirtualBox 4 & 5,
Seoul, and our
[https://genode.org/documentation/articles/arm_virtualization - custom VMM] -
remained kernel specific.
Of course, last remaining bastions tempt to be taken! So last year, we started
the venture to unify our virtualization interface across different kernels.
Starting point was the already existing Genode VM interface of our custom VMM
on ARM. We took it and extended the interface with caution to the x86 world.
Having an eye on the requirements of our already supported VMMs on NOVA(x86),
namely VirtualBox and Seoul, the VM interface got extended with missing
features like multiple vCPU support and specific VM handlers per vCPU.
In parallel, we started to investigate the other x86 microkernels with regard
to hardware-assisted virtualization features, namely seL4 and Fiasco.OC.
Over several weeks, we iteratively extended the interface. On the one hand
we familiarized ourself with the kernel interfaces of seL4 & Fiasco.OC while
on the other hand considered known requirements of the NOVA microhypervisor.
Additionally, we kept our custom VMM for ARM still compatible with the new VM
interface.
During this time, it became apparent that the control flow on a VM resume/pause
and a VM event(exit) are different between seL4/Fiasco.OC and NOVA/base-hw.
For seL4 and Fiasco.OC, a VM is resumed by making a blocking syscall on the
kernel. On a VM event, the blocking syscall would return. Logically, on both
kernels the VMM 'calls' into the VM.
On base-hw and NOVA, it is the other way around. Whenever a VM causes a VM
event, the kernels set up either an asynchronous notification (base-hw) or a
synchronous IPC call (NOVA) to the VMM. In both cases the VMM executes a prior
registered VM event handler as response.
Upon return of the VM event handler, the kernel resumes the VM. Logically, on
NOVA and base-hw the VM 'calls' into the VMM. The following two figures
contrast the different flows of control between a user-level virtual machine
monitor and the respective kernels.
[image vm_seq_foc_sel4]
Control flow of handling virtualization events on Fiasco.OC and seL4
[image vm_seq_nova_hw]
Control flow of handling virtualization events on NOVA and the base-hw kernel
Hiding this differences behind a common VM interface was the challenge we were
faced, accepted, and won. Finally, at one point in December we had all 3
x86 kernels running with a test VMM - without re-compilation. The toy VMM
(vmm_x86.run) runs multiple vCPUs on multiple physical CPUs and tests several
VM events/exits.
After this major breakthrough, we spent the days left before Christmas to
adjust the Seoul VMM to the new VM interface, freeing it from the ties to the
NOVA kernel. The choice to start with Seoul stems from the fact that it is -
compared to VirtualBox - much smaller and therefore easier to debug if things
go wrong in the beginning. After one week, the Seoul VMM became in principle
kernel independent and worked again on NOVA. After some more days, it started
to hobble on seL4 and Fiasco.OC as well.
With the New Year, VirtualBox was the next target where all NOVA kernel
specific calls were replaced with the new Genode VM interface. Mid of January,
the work showed first results by having a prototype running simple VMs on NOVA
again. At this point, it became apparent that this venture is not anymore an
adventure. All the findings and technical details so far got condensed to a
[https://fosdem.org/2019/schedule/event/microkernel_virtualization - presentation]
given and recorded at the [https://fosdem.org/2019 - FOSDEM 2019] in Brussels
in February in the
[https://fosdem.org/2019/schedule/track/microkernels_and_component_based_os - Microkernel and Component based OS]
developer room.
At this point, we started transforming our prototype for the 4 kernels into a
clean solution to be featured in Genode 19.05. Eventually, the kernel-agnostic
Seoul VMM runnable on seL4, Fiasco.OC, and NOVA entered Genode master. In the
Genodians article
[https://genodians.org/alex-ab/2019-05-09-seoul-vmm - Seoul VMM and the new VM interface],
we conserved the current state and a few performance measurements.
Shortly before this release, the kernel-agnostic VirtualBox VMM version on
Genode/NOVA got ready. The kernel-agnostic version is in principle capable to
run Linux VMs and Windows 7/10 VMs on Genode/NOVA. Currently, this version
must still be considered as experimental and does not run on seL4 or
Fiasco.OC.
Because of the experimental nature of the kernel-agnostic VirtualBox VMM
version, we decided to keep the kernel-specific version for NOVA for the
moment. This gives us time to test and improve the kernel-agnostic version. It
also allows us to compare both versions to each other.
If time and interest permits, we will consider bringing the virtualization
support on Genode/seL4 and Genode/Fiasco.OC on par with Genode/NOVA.
When building VirtualBox with Genode 19.05,
you will find both the 'virtualbox5-nova' and the new 'virtualbox5' binaries
in the build directory. The former relies on NOVA's kernel interface whereas
the latter uses Genode's kernel-agnostic VM interface. Nightly tested run
scenarios with the new VM interface are named 'vbox5_vm*.run' and can be found
in the 'repos/ports/run' directory.
Broadened CPU architecture support and updated tool chain
#########################################################
With the major update of Genode's tool chain and library infrastructure in
tandem, the framework gains a consistent architecture support across x86-32,
x86-64, ARM-32, RISC-V, and the newly added AARCH64. This includes the tool
chain (Section [Tool chain based on GCC 8.3.0 and binutils 2.32]), the base
framework, the dynamic linker, and the C runtime
(Section [Updated dynamic linker and C runtime]).
Together with this update, we took the chance to wrap up our long-time move
away from board-specific build directories to one generic build directory
shared by multiple kernels and boards for a given CPU architecture
(Section [Unified build directories for ARM]).
Tool chain based on GCC 8.3.0 and binutils 2.32
===============================================
Genode uses a tailored tool chain based on GCC and binutils that is used
across all supported kernels and architectures. Since the previous tool-chain
update in version
[https://genode.org/documentation/release-notes/17.05#Tool_chain - 17.05],
we relied on GCC 6.3. After two years, it was time for an update, motivated by
three major reasons. First, the C++17 standard is common-place now. We Genode
developers anticipate the improvements that come with it. Second, RISC-V and
AARCH64 are now supported by mainline GCC. Up till now, we had to maintain a
custom patch set for Genode's RISC-V support. AARCH64 was not supported yet.
Third, our increasing engagement with SPARK depends on recent improvements of
the Ada compiler that is part of GCC.
With Genode 19.05, the tool chain is now based on binutils version 2.32, GCC
version 8.3.0, GDB version 8.2.1, gcov version 8.3.0, standard C++ library
version 8.3.0.
The tool chain supports x86 (32 and 64 bit), ARM, AARCH64, and RISC-V.
For C++ code, the C++17 standard is enabled by default.
The update of the tool chain provided a perfect opportunity to replace the
former use of gnatmake with a much more natural integration of Ada in Genode's
build system, using a custom ali2dep dependency-extraction tool developed
by [https://github.com/Componolit/ali2dep - Componolit].
In contrast to the previous versions, we switched to a versioned installation
directory for the new tool chain. By default, it is now installed to
_/usr/local/genode/tool/19.05/_. This eases the use of different tool-chain
versions for different development branches.
:Tool-chain installation:

Caveats
-------
The tool-chain update required a number of adaptations throughout the source
tree, and may affect Genode users too:
* The silent fall-though within switch statements must now be replaced
by an explicit annotation of the form
! [[fallthrough]]
* The 'register' keyword is no longer valid with C++17. Hence, it must
be removed from the code.
* Types marked as 'Noncopyable' can no longer have an implicit default
constructor. A default constructor must be provided manually.
Updated dynamic linker and C runtime
====================================
The tool-chain update is accompanied with a major update of the dynamic linker
and the C runtime to cover both the AARCH64 and RISC-V architectures in
addition to the traditional x86 and ARM architectures.
FreeBSD 12 supports AARCH64 and RISC-V. Hence, by updating our C runtime to
this version, Genode's libc support extends to those architectures now.
Until now, Genode's dynamic linker supported only the eager binding of symbols
at loading time on the *RISC-V* architecture. With the current version, we
lifted this limitation in favor of lazy binding as used on all other CPU
architectures.
Unified build directories for ARM
=================================
In version
[https://genode.org/documentation/release-notes/17.02#Genode_Application_Binary_Interface - 17.02],
we introduced unified build directories for x86, which allow us to build and
run Genode scenarios on various kernels while using only one build directory.
This concept leverages Genode's cross-kernel binary compatibility to make
the switch from one kernel to another - like developing on base-linux and
deploying on base-nova - a seamless experience.
On ARM, this concept was held back by a third dimension. The
system-integration step does not only depend on the CPU architecture and
the kernel but also on the used board. Our traditional approach was the
use of one build directory per board. Granted, within such a build directory,
one could easily switch between different kernels like Fiasco.OC and seL4.
But on ARM, we find an extreme proliferation of different board
configurations, which share the same CPU architecture but demand different
integration steps. This ensues large redundancies among different build
directories. Switching from one board to another - even when most binaries
happen to be exactly the same - requires an additional rebuilding effort.
With version 19.05, we took the chance to generalize the unified build
directory concept to support multiple different boards per build directory,
greatly reducing the friction when switching kernels and boards for a given
CPU architecture (like ARMv7a). This change has the following implications:
* Drivers no longer depend on the SPEC values as configured for a build
directory.
* All *binaries* are now *named unambiguously*. For example, the USB drivers
for the Panda (OMAP) and Arndale (Exynos) boards were formerly called
'usb_drv' but were different programs. They just never happened to
appear in the same build directory. In the new version, they are named
'panda_usb_drv' and 'arndale_usb_drv' respectively and can thereby
peacefully co-exist within the same 'armv7a' build directory.
Note that this binary renaming will likely affect existing run scripts.
* Include paths no longer hide the board details, which makes the included
code much more easy to follow.
* Run scripts need to pick the right binary, depending on the used board.
Since the board is no longer tied to a build directory, the selection
of the used board has become a build-time variable 'BOARD' following
the successful pattern of how we specify the targeted 'KERNEL'.
To avoid the pollution of run scripts with difficult conditions, we wrap
the drivers needed for a particular board and use case into so-called
_drivers_ packages. Such a package can be instantiated within a generic
scenario using a nested init instance. The details about the drivers and
how they access the hardware remain nicely hidden inside this building block.
Currently, there exist _drivers_ packages for two distinct use cases:
:drivers_interactive pkgs: contain all drivers needed for simple
interactive scenarios, including graphical output and user input.
:drivers_nic pkgs: contain the drivers needed for communication over the
network.
Whenever a run script fits one of these use cases, it can rely on the
corresponding ready-to-use drivers packages via:
! import_from_depot [depot_user]/src/[base_src] \
! [depot_user]/pkg/[drivers_nic_pkg] \
! ...
With the drivers package incorporated, the drivers subsystem can be
instantiated as follows (note the absence of any board or kernel-specific
details):
! <start name="drivers" caps="1000">
! <resource name="RAM" quantum="32M" constrain_phys="yes"/>
! <binary name="init"/>
! <route>
! <service name="ROM" label="config">
! <parent label="drivers.config"/> </service>
! <service name="Timer"> <child name="timer"/> </service>
! <any-service> <parent/> </any-service>
! </route>
! <provides> <service name="Nic"/> </provides>
! </start>
Using the 'BOARD' build variable
--------------------------------
The new 'BOARD' variable selects the board to use. It can be specified either
as a 'make' command-line argument (or environment variable), or defined in the
build-directory configuration (_etc/build.conf_). The following boards are
available:
:arm_v6: rpi
:arm_v7a: arndale, imx53_qsb, imx53_qsb_tz, imx6q_sabrelite, imx7d_sabre,
nit6_solox, odroid_x2, odroid_xu, panda, pbxa9, usb_armory,
wand_quad, zynq_qemu
:arm_v8a: rpi3
:x86_64: pc, linux, muen
:x86_32: pc, linux
:riscv: spike
Please note, when running Genode on Linux or the Muen separation kernel -
although it is run on common x86 PC hardware - we treat both runtime
environments as separate "boards" because their device driver environments
are fundamentally different.

Base framework and OS-level infrastructure
##########################################
Modernized block-storage interfaces
===================================
With the current release, we revisited Genode's interfaces for accessing
block devices to ease the implementation of asynchronous I/O, to accommodate
zero-copy block drivers, and to support trim and sync operations.
Revised RPC interface
---------------------
The 'Block::Session' RPC interface remained untouched for a long time.
We have now rectified long-standing deficiencies.
First, *sync requests* used to be handled as synchronous RPCs. This is bad
for components like part_block that multiplex one block device for multiple
clients. One long-taking sync request of one client could stall the I/O for
all other clients. The new version handles sync requests as asynchronous
block-request packets instead.
Second, the new version allows a server to dictate the *alignment* of
block-request payload. This way, a driver becomes able to use the payload
buffer shared between client and server directly for DMA transfers while
respecting the device's buffer-alignment constraints.
Third, we added support for *trim* as an asynchronous block operation.
However, as of now, this operation is ignored by all servers.
Fourth, each block operation can now be accompanied with a client-defined
request tag independent from the other parameters of the operation. The tag
allows a block-session client to uniquely correlate acknowledgments with
outstanding requests. Until now, this was possible for read and write
operations by taking the value of the request's packet-stream offset. However,
sync and trim requests do not carry any packet-stream payload and thereby lack
meaningful and unique offset values. By introducing the notion of a tag, we
can support multiple outstanding requests of any type and don't need to
overload the meaning of the offset value.
New client-side API
-------------------
We have now equipped the 'Block::Connection' with a framework API for the
implementation of robust block-session clients that perform block I/O in an
asynchronous fashion.
An application-defined 'JOB' type, inherited from 'Connection::Job',
encapsulates the application's context information associated with a block
operation.
The life cycle of the jobs is implemented by the 'Connection' and driven by
the application's invocation of 'Connection::update_jobs'. The 'update_jobs'
mechanism takes three hook functions as arguments, which implement the
applications-defined policy for producing and consuming data, and for the
completion of jobs.
We plan to gradually move the existing block clients to the new API to benefit
from the latency-hiding effects of asynchronous I/O. The first updated client
is the _block_tester_ component located at _os/src/app/block_tester/_, which
received a number of new features like the choice of the batch size. Please
refer to the accompanied README for a detailed description of the
block-tester.
Unified types for time values
=============================
[https://genode.org/documentation/release-notes/17.05#New_API_for_user-level_timing - Two years ago],
we introduced the so-called timeout framework to provide a general solution
for requirements unmet by the bare timer-session interface - most notably
timer-session multiplexing amongst multiple timeouts, and microseconds
accuracy. Up to this day, the timeout framework has proved itself many times
in both real-life appliances and artificial tests and has become the standard
front end for timing in Genode applications.
With this release, we solved one of the few remaining limitations with the
framework by enabling timeouts of up to 2^64 microseconds (> 500000 years)
across all supported architectures. In order to achieve this, we replaced the
former machine-word-wide types used for plain time values by unsigned 64-bit
integers. We did this not only inside the timeout framework but also to almost
all code in the basic Genode repositories that uses the framework.
By doing so, we also paved the way for a second step, in which we are planning
to replace plain time values as far as possible with the abstract 'Duration'
type. With this type in place, the user wouldn't have to worry anymore about
any plain-integer implications when calculating with time values.
Support for chained EBR partitions
==================================
Having an active community around Sculpt leads to bugfixes in unexpected
places. By now we prefer to use a GPT rather than an MBR based partition table
and although we test 'part_block', the component that parses the tables, on
regular basis, the handling of chained EBR's was flawed. Community member
[https://genodians.org/valerius/index - Valery Sedletski] who relies on such a
setup encountered this flaw and provided a bug report, which enabled us to
quickly reproduce and fix the problem.
IP forwarding with port redirection
===================================
The NIC router can now be used to redirect to individual destination ports on
port-forwarding. To express the redirection, the new 'to_port' attribute can
be added to '<tcp-forward>' and '<udp-forward>' rules in the NIC router
configuration. If the new attribute isn't added, the rules behave as usual and
forward with an unaltered destination port.
Libraries, languages, and applications
######################################
Ada/SPARK runtime and SPARK-based cryptography
==============================================
The SPARK runtime has been updated to GCC 8.3. SPARK components do not require
'Genode::Env' or a terminal session anymore. Debug messages can still be
printed using 'GNAT.IO', which uses 'Genode::log' and 'Genode::error'
internally now.
Threading support, which was never fully implemented, has been removed to
further simplify the runtime. This simplification allowed us to prove absence
of runtime errors for the secondary stack allocator and other parts of the
runtime.
[https://github.com/Componolit/libsparkcrypto.git - Libsparkcrypto] is a
library of common cryptographic algorithms implemented in SPARK. It is
free-standing and has a very small footprint. The port of libsparkcrypto for
Genode has been added to the libports repository. Thanks to Alexander Senier
and Johannes Kliemann of [https://componolit.com - Componolit] for maintaining
the Ada/SPARK runtime and libsparkcrypto.
To accommodate the use case of block encryption, we added the small wrapper
library 'aes_cbc_4k' around libsparkcrypto that provides a simple C++
interface for the en/decryption of 4 KiB data blocks. It uses AES-CBC while
incorporating the block number and the private key as salt values.
Improved resilience of the sequence tool
========================================
We have a simple component that starts other components sequentially. It
will exit whenever one of those components has exited with an error.
However, this component is used by our [https://genodians.org - Genodians]
appliance where it controls the content-update mechanism. Since updating
involves fetching content via HTTP/S depending on external events, e.g.,
the remote site is not reachable, the sequence tool might exit. In a long
running appliance, this is obviously not a useful action where no one is
in place to restart the sequence tool. Rather than increasing the overall
complexity of the appliance by introducing such a management component, we
added a _keep-going_ feature to the sequence tool that will instruct it
to carry on even if one of the started components has failed.
Please look at _repos/os/src/app/sequence/README_ for instructions on
how to use the feature.
NIC-bus server for private LANs
===============================
The 'nic_bus' server was added to the world repository as an alternative
to the 'nic_router' and 'nic_bridge' components. The name may be a slight
misnomer, but this component acts neither as a hub, switch, or router.
The 'nic_bus' implements unicast and multicast Ethernet packet switching
between sessions, but drops any unicast packet not destined for a session
attached to the bus. This is in opposition to the behavior of a typical
Ethernet switch and is intending to create simple, software-defined
local-area-networks for native components as well as virtual machines.
In practice the component has been used for attaching VMs to the
[https://yggdrasil-network.github.io/ - Yggdrasil] overlay network via
a bus-local IPv6 prefix.
Distributed Genode
==================
In
[https://genode.org/documentation/release-notes/16.08#Network-transparent_ROM_sessions_to_a_remote_Genode_system - 16.08],
we initially released the _remote_rom_ components that act as communication
proxies. A communication proxy transparently relays a particular service to
another Genode system. As the name suggests, the remote_rom relays ROM
sessions.
Originally implemented as a proof of concept using bare IP packets, broadcast
MACs and static configuration of IP addresses, we added several improvements
to allow a more general use. First, we adopted the size-guard idea for packet
construction and processing from the NIC router. Furthermore, we adopted the
single-threaded implementation style that was already established in other NIC
components. Thanks to Edgard Schmidt for this contribution. Second, we
implemented ARP requests to eliminate broadcasting. Third, we moved from bare
IP packets to UDP/IP and implemented a go-back-N ARQ strategy in order to
reliably transmit larger ROM dataspaces.
As the remote_rom proved valuable for distributing functionality across
multiple Genode devices, we also applied this concept to the LOG session in
order to transmit LOG output from a headless Genode device to a
[https://genode.org/download/sculpt - Sculpt] system for instance. The udp_log
component provides a LOG service and sends the LOG messages as UDP packets to
another machine. The log_udp reverses this process by receiving these UDP
packets and forwarding the messages to a LOG service. An example can be found
in the world repository at _run/udp_log.run_ and _run/log_udp.run_.
Seoul and VirtualBox virtual machine monitors
=============================================
Besides the conversion of the Genode back end of Seoul to the new VM
interface, we added mouse-wheel support to the PS/2 model and changed the VMM
to request a single GUI/nitpicker session rather than distinct framebufer and
input sessions.
Similar to the Seoul VMM, the VirtualBox VMM was adjusted to the new VM
interface and now uses the GUI/nitpicker session. The original kernel-specific
VirtualBox version tied to the NOVA kernel is still available. Both versions
can be used simultaneously.
Use of Nim decoupled from Genode build system
=============================================
With this release, all integration with Nim tooling has been removed from the
Genode build system as a result of maturing support for additional languages
via Genode SDKs. Building Nim components independently of the Genode source
tree has the benefit of smaller upstream checkouts and faster build times, and
has yielded components such as the
[https://genodians.org/ehmry/2019-03-22-depot_9P - 9P server] used in some
Sculpt developer workflows. An example of an independent build system for Nim
components is
[https://genodians.org/ehmry/2019-04-27-nim_packaging - documented on the Genodians blog].
OpenJDK improvements
====================
Within the 19.05 release cycle, we further improved Genode's OpenJDK support
by enabling additional networking infrastructure required by the
[https://spring.io - Spring Framework]. The improvements especially concern
support for SSL connections, which enabled us to successfully execute an embedded
[https://docs.spring.io/spring-boot/docs/current/reference/html/howto-embedded-web-servers.html - Tomcat]
server natively on Genode x86 and ARMv7 platforms using the same JAR archive.
This line of work continues our Java for embedded systems effort as described in
our [https://genodians.org/ssumpf/2019-02-27-java-19-02 - Boot2Java] article.
Having these features in place, our Java efforts will continue in the direction
of Java Swing and the support of input devices in the future, with the ultimate
goal of seamless Java application integration into
[https://genode.org/download/sculpt - Sculpt OS].
Device drivers
##############
Improved Zynq board support
===========================
The initial support of the Xilinx Zynq-7000 SoC was added to our custom kernel
in 15.11. Since then, the support of this hardware has been incrementally
extended. The definitions of memory maps, frequencies, and RAM sizes for
different Zynq-based boards are found in the world repository.
One of the major additions in this release is the initialization of the L2
cache. In this context, we also added a simple cache benchmark at
_repos/os/run/cache.run_ that measures the access times for memory regions of
different size and thereby reveals the number of cache levels and their sizes.
With the latest improvements of the network driver in 18.11, a zero-copy
approach was introduced as an effort to eliminate bottlenecks in the driver's
performance. However, this modification also introduced a kernel dependency of
the driver in order to flush packet-buffer memory from the cache before handing
it over to the DMA-controller. With this release, we moved back to using
uncached dataspaces in order to eliminate the cache flushes and the kernel
dependency. Interestingly, we could not recognize a significant impact on the
driver's performance, which confirms the presumption that flushing the cache
nullifies the gain from using cached dataspaces.
In order to enable the continuous operation of the network driver, we extended
the driver-internal error handling that is necessary to recover the network
driver in certain situations.
_Thanks to Johannes Schlatow for contributing and maintaining Genode's Zynq support!_
Updated Intel network drivers
=============================
As a result of recurring issues with modern Intel i219 laptop NICs, we
updated the driver sources for Intel chipsets to the latest upstream
iPXE version. This update also enables all NIC variants, which were
missing from our manually maintained PCI ID whitelist before.
New drivers-nic and drivers-interactive depot packages
======================================================
As already described in section [Unified build directories for ARM],
_drivers_nic_ packages nicely hide the driver configuration internals needed for
a specific board to communicate over the network. Until now there was only one
package available for x86 based PCs. Now, additional _drivers_nic_ packages
are available for:
:boards: imx53_qsb imx6q_sabrelite linux muen pbxa9 rpi zynq
Beside the formerly available _drivers_interactive_ packages for linux, pbxa9
and pc, there are now additional ones for the following:
:boards: imx53_qsb rpi muen
Platforms
#########
For most kernel environments, the core component provides a ROM module named
'platform_info', which comprises information provided by either the kernel or
the bootloader. The information entails e.g., the TSC clock frequency and
framebuffer dimensions. Most of the information is of interest for special
device driver components only.
Over the time, there was an increasing need to incorporate the information
about which kernel Genode runs on top of. Thereby, special test components,
like depot_autopilot could use the information to, e.g., skip certain tests
on kernels known to not support them. Moreover, there are rare corner-cases
where kernels behave differently, for instance, interrupts are enumerated
differently on certain ARM platforms. Rather than maintaining multiple driver
binaries with different names depending on specific kernels, the
'platform_info' ROM module can now be used to differentiate between kernels
when necessary.
Execution on bare hardware (base-hw)
====================================
This release comes with fundamental optimizations and corrections for
executing Genode on bare hardware when using the core component as the actual
kernel.
In the past, we could observe some serious peculiarities regarding the timing
behavior on the hw kernel. After a careful review, we identified the obstacles
that led to time drifts on several platforms and to quite different runtime
execution.
First and foremost, we limited the CPU-load wasted by the kernel, which
unnecessarily made new scheduling decisions quite often. When the hw kernel
was started as an experiment, there was less focus on performance, but more on
simplicity. Instead of caring about state changes that make a scheduling
decision necessary, the scheduler was asked for the next execution context
unconditionally, whenever the kernel was entered. Now, the scheduler gets
invoked only whenever an execution context gets blocked, or unblocked, or if
the kernel's timer fires due to a timeout. This dramatically influences the
CPU-load caused by the hw kernel in a positive way.
The timing accuracy got increased by reworking most hardware timer drivers
used in the kernel to let the timer never stop counting. Moreover, we limit
the scope in between reading the clock and adjusting the next timeout to a
minimum. The whole internal time representation got widened to 64-bit.
In some rare use cases, we could observe components that do I/O polling, and
thereby actively ask for pending signals, to starve. The reason was a gap in
the hw kernel's syscall API. Beside the ability to wait for signals, the
base-library offers the ability to check for pending signals without blocking
in the case of no available signals. The equivalent call in the kernel was
still missing, and is now present and integrated in the base-library of
base-hw.
ARM architecture
----------------
With this release, we add the i.MX 7 Dual SABRE reference board to the rich
hardware zoo Genode runs directly on top of. This includes the use of the
virtualization extensions available on this platform.
Apart from the new board support, several optimizations were added
specifically for the ARM architecture. Several unnecessary cache maintenance
operations were eliminated, which resided in the code base since the time when
the kernel used a separate address-space only. Moreover, the kernel-lock -
used when several execution contexts on different CPU-cores try to enter the
kernel - does not spin anymore. Instead, the CPU goes into a sleep-state to
save energy. As a side-effect, multi-core scenarios become usable when
executed in Qemu.
X86 architecture
----------------
Since the newly used compiler version makes aggressive use of FPU instructions
including the core component, the kernel itself makes use of FPU registers and
state. Therefore, lazy FPU switching becomes a no go for base-hw. Although, we
incorporated eager FPU switching into the ARM-specific part of the hw kernel
already, the x86 version was still missing it. Now, the FPU context of a thread
gets saved and restored on every kernel entry and exit on x86 too.
Updated Muen separation kernel
==============================
The Muen port has been updated to the latest development version, which comes
with many improvements under the hood. Most notably this version of Muen brings
support for Linux SMP subjects, GNAT Community 2018 toolchain support as well
as much improved build speed, which is most noticeable during autopilot runs.
Additionally, the debug server buffer size in the Genode system policy has been
increased to avoid potential message loss in case of rapid successive logging.
_Thanks to Adrian-Ken Rueegsegger of [https://codelabs.ch - Codelabs] for_
_this welcome contribution!_
NOVA microhypervisor
====================
The kernel got updated due to the tool-chain update to GNU G++ 8.3.0.
Additionally, several issues reported by Julian Stecklina regarding FPU and
page-table synchronization got addressed. The kernel memory allocation at boot
time got more flexible to address target machines with fragmented physical
memory. Additionally, the vTLB implementation is no longer used on AMD
machines whenever nested paging is available.
seL4 microkernel
================
With this release, we extend the variety of hardware to run Genode on top of
the seL4 kernel with NXP's i.MX 7 Dual SABRE reference board. To do so, we had
to update the seL4 tools used to craft a bootable ELF image to a state that is
consistent with the currently supported seL4 kernel version 9.0.1.
As a side-effect of this development work, the General Purpose Timer (GPT) used
in the i.MX series can now be used as a timer service component.
Fiasco.OC microkernel
=====================
As with base-hw and seL4, we add the i.MX 7 Dual SABRE reference board to the
list of working hardware for Genode running on top of the Fiasco.OC
microkernel. Moreover, with Fiasco.OC it is now possible to take the first
steps using Genode on the ARM 64-bit architecture. Therefore, we add Raspberry
Pi 3 as a candidate board to be used with Genode/Fiasco.OC. Currently, only
basic tests without peripheral dependencies are supported.
Tooling and build system
########################
Improved handling of missing ports
==================================
The depot tools _tool/depot/create_ and _tool/depot/extract_ now detect and
report all missing third-party sources - called ports - for a given set of
archives at once. Additionally, the user can tell the tools to download and
prepare such missing ports automatically by setting the argument
'PREPARE_PORTS=1'. Please be aware that doing so may cause downloads and
file operations in your _contrib/_ directory without further interaction.
These features make building archives with dependencies to many ports more
enjoyable. If you merely need a list of ports that are missing for your
archives, you can use the new tool _tool/depot/missing_ports_.
For more details you may read the
[https://genodians.org/m-stein/2019-05-21-depot-missing-ports - article on genodians.org].
Automated depot management
==========================
When using the 'import_from_depot' mechanism of the run tool, one frequently
encounters a situation where the depot lacks a particular archive. Whenever
the run tool detects such a situation, it prompts the user to manually curate
the depot content via the _tool/depot/create_ tool. The need for such manual
steps negatively interferes with the development workflow. The right manual
steps are sometimes not straight-forward to find, in particular after
switching between Git branches.
To relieve the developer from this uncreative manual labor, we extended the
run tool with the option '--depot-auto-update' for managing the depot
automatically according to the needs of the executed run script. To enable
this option, use the following line in the build configuration:
! RUN_OPT += --depot-auto-update
If enabled, the run tool automatically invokes the right depot-management
commands to populate the depot with the required archives, and to ensure the
consistency of the depot content with the current version of the source tree.
The feature comes at the price of a delay when executing the run script
because the consistency check involves the extraction of all used source
archives from the source tree. In regular run scripts, this delay is barely
noticeable. Only when working with a run script of a large system, it may be
better to leave the depot auto update disabled.
Please note that the use of the automated depot update may result in version
updates of the corresponding depot recipes in the source tree (recipe hash
files). It is a good practice to review and commit those hash files once the
local changes in the source tree have reached a good shape.

Release notes for the Genode OS Framework 19.08
===============================================
Genode Labs
The stated theme of this year's [https://genode.org/about/road-map - road map]
is "bridging worlds", which expresses our ambition to smoothen the practical
use of Genode-based systems such as Sculpt OS. The current release pays
tribute to this ambition by addressing a great number of practical concerns:
How to accommodate the staggering variety of keyboard layouts out there?
(Section [Flexible keyboard layouts])
How can the system gracefully respond when confronted with exotic USB devices?
(Section [Storage-stack improvements])
How to set the system time from within the system? How does SNTP fit in here?
(Section [General system time concept])
How to approach the remote administration of the system?
(Section [Enhanced SSH terminal])
How to copy and paste text securely between mutually distrusting subsystems?
(Section [Clipboard])
Or how to overcome the captive portal of a Hotel WiFi with Sculpt OS?
(Section [Disposable VM for handling captive portals])
By providing answers to those questions, we believe to make Genode - and Sculpt
OS in particular - generally more useful.
As another take on "bridging worlds", we continue our effort to bring the rich
Sculpt OS software stack to the 64-bit ARM world, in particular to our most
loved SoC family, namely NXP i.MX. Section [64-bit ARM and NXP i.MX8] reports
on our progress in this direction.
Under the hood, there are a few exciting developments that will greatly reduce
the effort of running existing software on Genode. In particular, Genode's
(entirely optional) C runtime has gained the ability to emulate the
traditional execve and fork mechanisms.
(Section [Consolidation of the C runtime and Noux]) This will eventually
alleviate the need for our present noux runtime environment to the benefits of
better performance and increased flexibility.
Further highlights of Genode 19.08 are a major update of Qt5 to version 5.13
(Section [Updated Qt5]) and the continuation of our kernel-agnostic
virtualization story (Section [Virtualization]).
Flexible keyboard layouts
#########################
Genode is used worldwide in a multilingual context beyond Germany and common
technical realms of English. Therefore, we had to address localized
keyboard-input handling for quite some time now and introduced the
_input-filter_ component in
[https://genode.org/documentation/release-notes/17.02#Input-event_filter - 17.02].
The component merges input streams and applies several forms of input
transformations, in particular the application of keyboard layouts to
supplement the input-event stream with character events.
But as we are by no means localization experts, our solution, while performing
a solid job for selected layouts, also had some quirks and rough edges when it
came to French or even Swiss German. First, our oversimplified notion of
[https://en.wikipedia.org/wiki/Caps_Lock - Caps Lock] as _just a pressed Shift_
_key_ is plain wrong but part of all our character-generator configurations.
We just missed this drawback because none of our developers uses Caps Lock
regularly. Further, US English and Germany layouts work very well without
[https://en.wikipedia.org/wiki/Dead_key - dead keys], but crossing any German
border (except the Austrian) is impossible without support for key sequences
composing special characters. The French keyboard layout in Genode tried to
alleviate the lack of compose sequences by adding an additional Circumflex
modifier and character mapping, which unfortunately is not standard.
[image keyboard_stack]
Beginning at this state of affairs, we researched common practice in
international keyboard-input handling, sought a quasi-standard source for
layout configurations, and addressed the drawbacks mentioned before. During
our research we found out that no current implementation is void of critique
and, therefore, decided to look more into X11/XKB as our open-source
quasi-standard solution, but always had an eye on the proprietary world.
The handling of key events in X11/XKB happens on three layers.
:Key codes: On the key-code layer, the device driver programs the
keyboard and generates a stream of key-code (i.e., scan-code)
events, which represent the physical location of the actual key on
the keyboard.
:Key symbols: These key codes are mapped to key symbols, which
represent the label imprinted on the key. So, the key code producing
US English _Q_ (QWERTY keyboard) generates _A_ on a French keyboard
(AZERTY). Modifiers like Shift, AltGr, and Caps Lock are included in
the key-symbol mapping. Additionally, some layouts map key codes to
dead key symbols, which start the before-mentioned compose
sequences. Key repeat is also implemented as key-symbol repeat
actually.
:Characters: On top of this stack, the key symbols are mapped to
characters represented as Unicode codepoints or UTF-8 strings.
The procedure obviously includes key symbols that have no character
representation (e.g. Control and Alt). Key symbols forming a valid compose
sequence generate characters on this level (e.g., dead-key circumflex plus
e generates ê).
We limited our research to Western keyboard-input handling and only had a
blink into the direction of Chinese-Japanese-Korean (CJK) and advanced input
methods (IM). This simplification is supported by the fact that CJK can also
be based on the mechanisms mentioned with some limitations only. Nevertheless,
we do not expect to never touch this topic again.
After doing our homework of keyboard-input handling, we worked on squeezing
all available layout information out of X11/XKB, which resulted in a small
tool residing in _tool/xkb2ifcfg_. For those wondering, the name is just a
silly acronym for _XKB to input-filter_ _configuration_ that pays tribute to
the boringness of this task. After building the tool by a run of 'make' in the
tool path, it can be used as follows. Please make sure you have libxkbcommon
development packages installed beforehand.
! xkb2ifcfg generate <layout> <variant> <locale>
!
! xkb2ifcfg generate us euro en_US.UTF-8
! xkb2ifcfg generate de nodeadkeys de_DE.UTF-8
If the parameter combination is available, xkb2ifcfg prints a input-filer
chargen configuration for the selected layout to standard output. Valid
'layout' and 'variant' options can be figured out from the LAYOUTS section in
'man 7 xkeyboard-config', where 'variant' strings are depicted in parentheses
after the layout (e.g., 'us(euro)'). The 'locale' option has the standard
locale syntax (see /usr/share/i18n/locales). The tool needs all three
parameters to gather the correct key-map and compose-sequence information. The
generated chargen configurations include '<map>' and '<key>' nodes
corresponding to significant modifier states and '<sequence>' nodes (described
later). For simplicity of the generator, the '<key>' nodes always use the
'code="..."' attribute, but also have a comment with the UTF-8 character
appended.
! <key name="KEY_MINUS" code="0x00df"/> <!-- ß -->
Last, we addressed the improvement of the input-filter character generator and
the actual chargen configuration files in Genode. Therefore, we specified the
modifier configuration assumed by the standard chargen files as '<mod1>'
corresponds to Shift, '<mod2>' to Control, '<mod3>' to AltGr, and '<mod4>' to
Caps Lock.
! <mod1> <key name="KEY_LEFTSHIFT"/> <key name="KEY_RIGHTSHIFT"/> </mod1>
! <mod2> <key name="KEY_LEFTCTRL"/> <key name="KEY_RIGHTCTRL"/> </mod2>
! <mod3> <key name="KEY_RIGHTALT"/> </mod3> <!-- AltGr -->
! <mod4> <rom name="capslock"/> </mod4>
As outlined above, the '<key>' nodes generated by xkb2ifcfg always use the
'code' attribute for the Unicode codepoint. Because of this and because UTF-8
also refers to codepoints, we deprecated the 'b0/b1/b2/b3' attributes for
character definition with this release.
The chargen is also extended by the '<sequence>' configuration node. A
sequence node permits the definition of dead-key/composing character
sequences. With such sequences, the character is not generated instantly on
key press but only after the sequence is completed. If an unfinished sequence
can't be completed due to an unmatched character, the sequence is aborted and
no character is generated. We support sequences of up to four characters at
the moment.
For example, the French AZERTY
[https://docs.microsoft.com/en-us/globalization/keyboards/kbdfr.html - keyboard layout]
has a dead key for Circumflex Accent _^_ right of the _P_ key (which is
bracket left _[_ on US keyboards). When Circumflex is pressed no visible
character should be generated instantly but the accent must be combined with a
follow-up character (e.g., Circumflex plus _a_ generates _â_).
Dead keys can be defined in the '<key>' nodes of any '<map>' by using
codepoints not used for direct output, for example, Combining Diacritical
Marks beginning at U+0300. The French Circumflex example can be configured
like follows.
! <mod1>
! <key name="KEY_LEFTSHIFT"/> <key name="KEY_RIGHTSHIFT"/>
! </mod1>
! <map>
! <key name="KEY_Q" code="0x0061"/> <!-- a -->
! <key name="KEY_LEFTBRACE" code="0x0302"/> <!-- dead_circumflex -->
! </map>
! <map mod1="true">
! <key name="KEY_Q" code="0x0041"/> <!-- A -->
! </map>
! <sequence first="0x0302" second="0x0061" code="0x00e2"/> <!-- â -->
! <sequence first="0x0302" second="0x0041" code="0x00c2"/> <!-- Â -->
Fortunately, the configuration is automatically generated by xkb2ifcfg, but
admittedly quite extensive. Therefore, we manually amended the chargen
configurations before adding them to Genode, which also gave us the chance to
apply some adjustments like follows for AltGr in Swiss German.
! <map mod1="false" mod2="false" mod3="true" mod4="false">
! <key name="KEY_1" code="0x00a6"/> <!-- ¦ (*) -->
! <key name="KEY_4" code="0x00b0"/> <!-- ° (*) -->
! <key name="KEY_5" code="0x00a7"/> <!-- § (*) -->
! </map>
Beside the advanced input methods mentioned before, there are still loose ends
we are going to address in the upcoming releases. For example, the current key
handling in our Qt5 back end maps localized key symbols incorrectly (think
AZERTY vs. QWERTY) in combination with shortcuts like Ctrl-A.
64-bit ARM and NXP i.MX8
########################
64-bit ARM support in our custom base-hw kernel
-----------------------------------------------
By introducing rudimentary Raspberry Pi 3 support on top of the Fiasco.OC
kernel in the previous release, the first ARM 64-bit support has entered the
Genode OS framework. We continued pursuing the ARM 64-bit path and introduce
support for Raspberry Pi 3 as well as the i.MX8 evaluation kit (EVK), this
time using our own base-hw kernel.
Noteworthy additions in the base-hw kernel are support for the AARCH64 system
level architecture, and the use of the modern GIC v3 interrupt controller on
top of the i.MX8 EVK board. In comparison to the GICv2, GICv3 adds support for
more than eight CPUs, more than 1020 interrupt IDs, and offers fast register
access to the CPU interface, instead of memory-mapped I/O access. Minor
changes had to be made to the page-table implementation of ARMv7 with Large
Physical Address Extension (LPAE) to re-use it for ARMv8. Moreover, the
internal kernel API for TLB maintenance needed to be changed slightly for all
ARM platforms.
We expanded our regular testing infrastructure with two AARCH64 platforms,
namely Raspberry Pi 3 via Qemu and the NXP i.MX8 EVK board as physical
hardware. Both platforms are driven with a single CPU core only at the moment.
Network driver for i.MX7 and i.MX8
----------------------------------
We updated the 'fec' network driver to version 4.16.3, which adds support for
i.MX7 and i.MX8 SoCs. This makes i.MX8 a viable platform for Genode-based
networking scenarios.
Enhanced packaging and test infrastructure for ARMv8
----------------------------------------------------
Besides the improved base-hw kernel, we enabled additional infrastructure for
ARMv8 platforms. For example, noux packages - like _coreutils_, _bash_ - are
now available, the standard C++ library is in place, and support for Genode's
port of the Linux TCP/IP stack is enabled.
Additionally, ARMv8 is now regularly tested within our nightly
_depot_autopilot_ runs.
Base framework and OS-level infrastructure
##########################################
Tracing
=======
Support for fast tracing has been built into Genode for a long time. However,
the stakes to take advantage of this feature remained high because convenience
functions were not in place. With the current release, we added the support
for easy trace setups through a VFS plugin. The plugin is called _vfs_trace_
and can be mounted into a Genode component as follows:
!<config>
! <vfs>
! <trace ram=32MB/>
! </vfs>
!</config>
This configuration will create a trace file system at the root of the VFS. The
_ram_ attribute is mandatory and determines the maximum size of all trace
buffers. The file system forms a recursive directory structure that represents
the parent/child relationship of running components, whereas the leaf
directories represent single threads within a component. Each leaf directory
currently contains three files:
:'enable': Start or stop the tracing of a thread by writing "true" or "false"
into the file.
:'buffer_size': Allows for the configuration of the trace-buffer size for the
thread in the usual Genode format (e.g. 5M, 512K, 1024).
:'trace_buffer': This read-only file contains the current content of the trace
buffer. Each trace entry can only be read once, after that only new entries
appear. "tail -f" can also be used to display continuous output.
As an example, tracing is started by writing _true_ to the _enable_ file:
! echo "true" > enable
The trace buffer can then be displayed using Unix tools like _tail_
! tail -f trace_buffer
which provides a continuous output.
Additionally, we have added the _trace_ function to _base/log.h_ that
facilitates identical functionality as _Genode::log_
! Genode::trace("Tracepoint value: ", value);
In order to enable tracing, the parent must provide the "TRACE" service. For a
real world example on Sculpt OS, please refer to this
[https://genodians.org/ssumpf/2019-06-18-trace_fs - Genodians article].
With the _vfs_trace_ plugin in place, we removed the outdated _trace_fs_.
Consolidation of the C runtime and Noux
=======================================
On our [https://genode.org/about/road-map#August_-_Release_19.08 - road map],
we vaguely hinted at our plan for the "consolidation" of the noux runtime,
which is actually meant as a polite way of announcing that we are going to
remove it. We introduced the
[https://genode.org/documentation/release-notes/11.02#Noux_-_an_execution_environment_for_the_GNU_userland - Noux runtime]
in 2011 as a way to execute command-line-based GNU software directly on
Genode. It has served us well over the years and is - in fact - a crucial
ingredient of Sculpt OS and other system scenarios such as the Genodians.org
web server. Noux supplements Genode with two valuable assets, namely a
flexible and expandable virtual file system (VFS) layer, and the
implementation of the
[https://genode.org/documentation/release-notes/12.02#Noux_support_for_fork_semantics - Unix way]
to spawn applications ('fork' and 'execve').
In the
[https://genode.org/documentation/release-notes/17.02#Enhanced_VFS_infrastructure - meantime],
noux' VFS implementation has become independent from the noux runtime and is
now prominently employed by Genode's C runtime and the VFS server component.
Genode's C runtime became more and more complete, alleviating the use of noux
as POSIX compatibility layer except for programs that depended on a working
implementation of 'fork' and 'execve'.
The current release fills this remaining gap in Genode's C runtime by
providing 'fork', 'execve', and cousins such as 'wait4' and 'getpid' as
regular parts of the libc. This will eventually make noux redundant.
Note that this change does *NOT* make Genode reliant on POSIX. The C runtime
including the Unix features are entirely optional.
As one stepping stone of this undertaking, noux applications, which previously
had to be compiled for noux, have become binary compatible with the regular C
runtime. So one can execute programs like 'bash' directly as a Genode
component without any friction.
There are a few collateral improvements of Genode's dynamic linker and the C
runtime on the account of the new 'fork' and 'execve' implementation. E.g., in
addition to the already supported 'stdin', 'stdout', and 'stderr'
configuration, the libc can be instructed to initialize arbitrary file
descriptors as follows:
! <config>
! ...
! <libc ...>
! <fd id="3" path="/dev/log" writeable="yes" readable="no" seek="10"/>
! ...
! </libc>
! </config>
The libc-based implementation of 'fork' and 'execve' can be tried out via
the new _ports/run/bash.run_ script. Note that there are still a number of
limitations such as the lack of signal and ioctl handling. Pipes are not
supported, and shebangs ('#!') are not interpreted yet. That said, once those
missing pieces come into place, we can fade out the use of noux within Genode.
General system time concept
===========================
Briefly speaking, up to now there has been no notion of an overall concept of
system time in Genode. Components that need to have access to some kind of
real time are either configured locally, e.g., libc-based components access a
configured "device" (/dev/rtc), which just might be an inline file system
containing an artificial timestamp or the VFS RTC plugin, while other
components query some RTC session directly. Most of the time, this session is
provided by the 'rtc_drv' on x86 machines, which is somewhat costly as reading
the RTC via I/O ports takes time and is therefore done scarcely. For example,
the libc will query an RTC source only once and uses this initial value to
interpolate the current time. However, for executing long-running components,
it will be necessary to adjust the clock to compensate for any occurring clock
drift or to correct a misconfigured clock in general. In addition it is
desirable to be able to use a remote time source, e.g., an NTP-server, to
synchronize the system time.
To address this, we came up with the following concept:
[image system_rtc]
The new "System RTC" component, located at
_repos/libports/src/server/system_rtc_, acts as proxy for the RTC service in
front of the actual RTC driver. It uses the driver to get the initial RTC
value and then uses a timer session (via the timeout framework) to locally
interpolate the time. In contrast to querying the RTC driver, querying the
System RTC is fast.
The RTC driver and the System RTC are bundled up together in the new
_drivers-rtc-pc_ package. The runtime of this package requests two ROM modules
used to update the RTC value. The first one, named 'system_set_rtc', is used
to update the proxy component while the second one, called 'hw_set_rtc', is
used by the RTC driver to write the value into the battery-backed RTC. A
separate component, potentially accessing a remote time source, may generate
these ROMs to adjust the time in the package's runtime.
The new native *SNTP* client at _repos/libports/src/app/sntp_client_ is such a
component. It periodically requests the current time from a given SNTP server
and generates a report. The report produced by the component contains the time
as UTC/GMT. Depending on the system policy, it can be used to update the time
of the System RTC and/or instruct the driver to set the RTC value.
To propagate such changes to RTC values, the RTC session was enhanced by the
new 'set' signal. A client of the session can install a signal handler to
adapt its own time when necessary. Based on this, the time back end of the
libc was changed to instantiate a watch handler for the RTC device, which,
when triggered, will cause the libc to re-read the RTC value.
This constellation should, under normal operation, allow for second to
sub-second granularity updates of the overall system time and avoid drifting
away from network time.
Accessing SMBIOS tables
=======================
The System Management BIOS (SMBIOS) is a specification that allows for reading
management information produced by the BIOS of a system as a collection of
data structures in memory. It has the potential to eliminate the need for the
operating system to probe hardware for discovering present devices and their
characteristics. Nowadays, the SMBIOS specification is implemented widely in
PC systems, which includes modern UEFI systems as well. The data structures
are referred to as _tables_ or _records_ by public documentation.
The new native SMBIOS decoder at _os/src/app/smbios_decoder_ can be used on
x86 to parse SMBIOS tables and report gathered information in a human-readable
way. Besides general table information like number and size of structures,
etc., the component supports complete parsing of SMBIOS structures of types
"BIOS", "System", and "Baseboard".
The component is free from any code for acquiring an SMBIOS table through
means like the bootloader or BIOS information. It expects a table to be
present through a regular Genode ROM session with a 'smbios_table' label. This
way, the underlying system is required to find, select, and save the raw table
on startup and create a ROM module out of it. This is currently achieved on
NOVA and base-hw through an interplay of kernel, the core component, and the
ACPI driver and was tested for legacy BIOSes as well as UEFI systems.
Clipboard
=========
Genode introduced a principle copy-and-paste mechanism already
[https://genode.org/documentation/release-notes/15.11#Copy_and_paste - four years ago].
However, originally created as a part of a tech demo, the mechanism remained
unused in our day to day Genode work. This changed now. We took the
integration of copy-and-paste support in Sculpt OS as an opportunity to revive
and refine the existing mechanism and supplement it with the features needed
to make it practical for daily use. We believe that the result aligns ease of
use nicely with security. The concept is described in a
[https://genodians.org/nfeske/2019-07-03-copy-paste - dedicated article]
at Genodians.org.
On a technical level, the existing clipboard component has received a new
option that allows for dynamic information-flow policies based on user
interactivity (keyboard focus, activity). When setting the config attribute
'match_labels="yes"', the clipboard performs plausibility checks for copy and
paste operations against the focus of the Nitpicker GUI server. All aspects of
the clipboard policy - including information-flow policies - have become
reconfigurable.
To make window-manager clients compatible with the clipboard's dynamic policy,
the window manager got enhanced with the ability to proxy the interaction with
the clipboard. GUI clients in turn - in particular the graphical *terminal* -
became able to interact with the clipboard. With the '<config>' attribute
'copy="yes"' specified, the terminal allows the user to select text to be
reported to a "clipboard" report. The selection mode is activated by holding
the left shift key. While the selection mode is active, the text position
under the mouse pointer is highlighted and the user can select text via the
left mouse button. Upon release of the mouse button, the selection is
reported. Vice versa, with the '<config>' attribute 'paste="yes"' specified,
the terminal allows the user to paste the content of a "clipboard" ROM session
to the terminal client by pressing the middle mouse button.
Finally, we integrated those new abilities into Sculpt OS and into several
installable packages, including virtual machines, the noux-system package,
and graphical Qt5-based applications.
Enhanced SSH terminal
=====================
This release paves the way for remotely managing Genode devices over SSH.
Until now, only interactive SSH sessions were supported. It is now possible to
execute commands from a remote SSH client. E.g., 'ssh noux@localhost -p 5555
"ls -hal /bin/"'. For non-interactive sessions, ssh_terminal requires a helper
component. This component is responsible to create the environment for the
command to run in. You can find an example for such a component at
_gems/src/test/exec_terminal_. It starts noux in a sub init and executes the
provided command inside of it. The new _ssh_exec_channel.run_ script gives a
demonstration on how this feature can be used.
This work is a contribution by Sid Hussmann of
[https://gapfruit.com - Gapfruit]. Thanks for this great new feature!
Storage-stack improvements
==========================
The desire of one Genode developer to exchange data via Iomega ZIP drives
between an Atari Falcon and Sculpt OS called for a number of small
improvements across several components of the storage stack.
First, the USB-block driver has been changed to exit on an initialization
failure instead of waiting for another (supported) device. This change enables
the Sculpt manager to detect such conditions and release the USB device
hardware by removing the driver component. Such a failed initialization may
happen with exotic USB-storage devices such as ZIP drives. With the device
released, however, it can be assigned to a virtual machine to access it using
a guest OS with a broader support of devices.
Second, the USB-block driver received new support for issuing the SCSI
START-STOP command at initialization time, thereby overcoming the ZIP-drive
initialization failure.
Third, we enhanced the part-block component with the ability to parse AHDI
partition schemes and detect the GEMDOS variant of FAT as used by Atari TOS.
Fourth, we enabled the Rump VFS plugin to access GEMDOS file systems. The
GEMDOS variant is readily supported by NetBSD's "msdos" file-system driver.
However, it must explicitly be enabled by a mount flag. Hence, we added the
principle ability for passing mount flags to NetBSD file-system drivers and
enabled the MSDOSFSMNT_GEMDOSFS flag based on the VFS plugin's config
attribute 'gemdos="yes"'.
With these changes in place, data can now be exchanged directly between
Atari-formatted disks and Sculpt OS. That said, advanced use cases such as
media changes at runtime are not covered yet.
Updated Ada/SPARK runtime
=========================
Genode's Ada/SPARK runtime is developed and maintained by
[https://componolit.com - Componolit]. Thanks for this excellent
collaboration!
The updated Componolit Ada runtime 1.1.0 increases the proof coverage and
cleans up the source-code structure. SPARK mode is now enabled wherever
possible and unneeded abstractions have been removed. Furthermore, the 64-bit
addition and subtraction have been proven to be free of runtime errors.
As a new feature, the runtime now supports the use of inline assembly in Ada.
The removal of unneeded features such as the incomplete threading support for
the secondary stack has greatly reduced the runtime's complexity while keeping
the current functionality available. Also GNAT.IO has been removed as its
implementation was incomplete and complex. A simpler replacement has been
introduced with 'Componolit.Runtime.Debug'.
Unrelated to Genode, the runtime now supports [https://muen.sk/ - Muen] and
the API/ABI of the runtime has been separated from the GNAT ABI.
Libraries and applications
##########################
Updated Qt5
===========
We updated our Qt5 port to the latest upstream version 5.13.0. Before
preparing the 'qt5' port, please make sure to build and install the updated
Qt5 host tools with the 'tool/tool_chain_qt5' script.
Virtualization
==============
As follow-up of our work on the
[https://genode.org/documentation/release-notes/19.05#Kernel-agnostic_virtual-machine_monitors - kernel agnostic virtual-machine monitor interface]
on x86, we added principle support to run our port of VirtualBox on
Genode/Fiasco.OC. We write _principle_ support, since we managed to get the
VMM running with Fiasco.OC, but unfortunately not all features required by the
VMM are available using the Fiasco.OC kernel, e.g., guest FPU registers, PDPTE
registers, and task-priority support. In practice this means that the VMs with
Windows and Linux come up to a certain point but will fail later whenever the
guest state runs out of synchronization between VMM and hardware. In contrast,
the Seoul VMM runs fine on Fiasco.OC since it does not depend on the mentioned
missing features.
Our main working items have been the completion of transfer of the available
guest registers and control flow synchronization improvements between VMM and
Fiasco.OC kernel. Additionally, the usage of priorities for VirtualBox's
pthreads in the VMM had to be disabled. Finally, some tests for VirtualBox
with Genode/Fiasco.OC are enabled for nightly regular testing now.
As a side topic, we added support for using the VirtualBox
[https://forums.virtualbox.org/viewtopic.php?f=2&t=82299&start=15 - CPU profile]
feature, which allows for presenting a different CPUID to the VM than the one
of the real CPU. This can help when running Windows 7 on a Kaby Lake or newer
CPU, which are considered _unsupported hardware_ and reason enough not to
receive security updates from Microsoft. The feature can be used on Genode by
adding the 'CpuProfile' attribute to the '<CPU>' XML node in the .vbox file,
like:
! <CPU CpuProfile="Intel Core i7-5600U">
Disposable VM for handling captive portals
==========================================
It is common that WiFi networks require the user to interact with a specific
web page before gaining access to full network functionality. Such captive
portal pages are completely individual to the accessed network and not limited
in the use of common web techniques. Therefore, their handling is best be done
using a fully-featured web browser like Mozilla Firefox.
This is where, in a Genode-based desktop system like Sculpt, a disposable VM
for hosting a minimal browser setup becomes desirable. Its goal is to unlock a
network for the native Genode surroundings with as little inconvenience as
possible just to be thrown away afterwards without any side effects on the
system.
Now, one could use the Firefox appliance VM of Sculpt (see the
[https://genode.org/documentation/release-notes/18.05 - release notes] or the
[http://genodians.org/alex-ab/2019-03-06-disposal-browser-vm - Genodians article])
for this. But this VM aims for a long-term browsing experience which, in the
context of mere captive-portal handling, brings some drawbacks like a much
higher RAM consumption or the required sessions for USB detection and shared
folders.
Furthermore, in the captive portal VM, there's no need for managing windows or
browser tabs. The one browser tab needed can always be shown in fullscreen. It
is also unnecessary for the browser to maintain a content cache or remember
user data. This can reduce resource consumption.
[image captive_portal_vm]
The VM we came up with is provided as package for Sculpt by Martin Stein
(depot user 'mstein'). You'll possibly need to manually add Martin's
[https://github.com/genodelabs/genode/tree/master/depot/mstein - depot key and download location]
to your Sculpt depot directory. After enabling this user, the captive portal
VM can be found in the Sculpt menu under "Depot -> mstein -> Virtual
Machines -> vbox5-nova-captive-portal".
The VM is based on a TinyCore 10 Linux with Xserver, i3 WM, and a tailored
Firefox browser. The package runtime doesn't need access to your file system,
it merely loads some ROMs into a RAM FS, so, it will completely forget any
changes made during a session. Therefore, it's also safe to simply remove an
instance via the Leitzentrale component-view once you don't need it anymore.
The guest additions are also included to make the VM window resizable.
Build system and tools
######################
At Genode Labs, we have used _tool/autopilot_ for the steering of tests in our
Continuous Integration workflow for almost a decade now. This implied various
improvements over the years and with the completion of our work on
[https://genode.org/documentation/release-notes/19.05#Unified_build_directories_for_ARM - unified build directories]
it was time to amend this handy tool once again. Unified build directories
support building all components for one CPU architecture in one directory
saving the build server from the redundant work we previously had with
board-specific directories. With the new notion of boards during builds, the
definition of the target platform when integrating Genode system scenarios is
now a triplet of _CPU architecture_, _board_, and _kernel_. This is reflected
in the new '-t <architecture-board-kernel>' command line option, which
instructs autopilot to generate a build directory for _architecture_ and
execute tests for the _board-kernel_ combination.
! autopilot -t x86_64-pc-sel4 -t x86_64-pc-nova -r run/log
The known options for '-k kernel' and '-p platform' are still supported with
the small change that the platform must now be defined as
_architecture-board_.
! autopilot -p x86_64-pc -k sel4 -k nova -r run/log
Autopilot now also documents the hidden feature to propagate custom 'RUN_OPTs'
via the 'RUN_OPT_AUTOPILOT' environment variable to the run tool executed.
Besides that, the tool always appends 'RUN_OPT' with '--autopilot'.
! RUN_OPT_AUTOPILOT="--depot-dir /data/depot" autopilot ...

Release notes for the Genode OS Framework 19.11
===============================================
Genode Labs
On our [https://genode.org/about/road-map - road map] for this year, we stated
"bridging worlds" as our guiding theme of 2019. The current release pays
tribute to this ambition on several accounts.
First, acknowledging the role of POSIX in the real world outside the heavens
of Genode, the release vastly improves our (optional) C runtime with respect
to the emulation of POSIX signals, execve, and ioctl calls. With the line of
work described in Section [C runtime with improved POSIX compatibility], we
hope to greatly reduce the friction when porting and hosting existing
application software directly on Genode.
Second, we identified the process of porting or developing application
software worth improving. Our existing tools were primarily geared to
operating-system development, not application development. Application
developers demand different work flows and tools, including the freedom to use
a build system of their choice.
Section [New tooling for bridging existing build systems with Genode]
introduces our new take on this productivity issue.
Third, in cases where the porting of software to Genode is considered
infeasible, virtualization comes to the rescue. With the current release, a
new virtual machine monitor for the 64-bit ARM architecture enters the
framework. It is presented in Section [Virtualization of 64-bit ARM platforms].
As another goal for 2019, we envisioned a solution for block-level device
encryption, which is a highly anticipated feature among Genode users. We are
proud to present the preliminary result of our year-long development in
Section [Preliminary block-device encrypter].
Preliminary block-device encrypter
##################################
Over the past year, we worked on implementing a block-device encryption
component that makes use of the
[https://en.wikipedia.org/wiki/SPARK_(programming_language) - SPARK]
programming language for its core logic. In contrast to common
block-device encryption techniques where normally is little done besides
the encryption of the on-disk blocks, the _consistent block encrypter (CBE)_
aims for more. It combines multiple techniques to ensure integrity -
the detection of unauthorized modifications of the block-device -
and robustness against data loss. Robustness is achieved by keeping snapshots
of old states of the device that remain unaffected by the further operation of
the device. A copy-on-write mechanism (only the differential changes to the
last snapshot are stored) is employed to maintain this snapshot history with
low overhead. To be able to access all states of the device in the same manner,
some kind of translation from virtual blocks to blocks on the device is needed.
Hash-trees, where each node contains the hash of its sub-nodes, combine the
aspect of translating blocks and ensuring their integrity in an elegant way.
During the tree traversal, the computed hash of each node can be easily checked
against the hash stored in the parent node.
The CBE does not perform any cryptography by itself but delegates
cryptographic operations to another entity. It neither knows nor cares about
the used algorithm. Of all the nodes in the virtual block device (VBD), only
the leaf nodes, which contain the data, are encrypted. All other nodes, which
only contain meta-data, are stored unencrypted.
Design
------
As depicted in Figure [cbe_trees], all information describing the various
parts of the CBE is stored in the superblock. The referenced VBD is a set of
several hash trees, each representing a certain device state including the
current working state. Only the tree of the current working state is used to
write data to the block device. All other trees represent snapshots of older
states and are immutable. Each stored device state has a generation number
that provides the chronological order of the states.
As you can see, in the depicted situation, there exist four device states - the
snapshot with generation 3 is the oldest, followed by two newer snapshots and
generation 6 that marks the working state of the virtual device. The tree with
generation 6 is the current working tree. Each tree contains all changes done
to the VBD since the previous generation (for generation 6 the red nodes). All
parts of a tree that didn't change since the previous generation are references
into older trees (for generation 6 the gray nodes). Note that in the picture,
nodes that are not relevant for generation 6 are omitted to keep it manageable.
The actual data blocks of the virtual device are the leaf nodes of the trees,
shown as squares.
[image cbe_trees]
Whenever a block request from the client would override data blocks in
generation 6 that are still referenced from an older generation, new blocks for
storing the changes are needed. Here is where the so-called _Free Tree_ enters
the picture. This tree contains and manages the spare blocks. Spare blocks are
a certain amount of blocks that the CBE has in addition to the number of blocks
needed for initializing the virtual device. So, after having initialized a
virtual device, they remain unused and are only referenced by the Free Tree.
Therefore, in case the VBD needs new blocks, it consults the Free Tree (red
arrow).
In the depicted situation, writing the first data block (red square) would
require allocating 4 new blocks as all nodes in the branch leading to the
corresponding leaf node - including the leaf node itself - have to be written.
In contrast, writing the second data block would require allocating only one
new block as the inner nodes (red circles) now already exist. Subsequent write
requests affecting only the new blocks will not trigger further block
allocations because they still belong to the current generation and will be
changed in-place. To make them immutable we have to create a new snapshot.
The blocks in generation 5 that were replaced by the change to generation 6
(blue nodes) are not needed for the working state of the virtual device
anymore. They are therefore, in exchange for the allocated blocks, added to
the Free Tree. But don't be fooled by the name, they are not free for
allocation yet, but marked as "reserved" only. This means, they are
potentially still part of a snapshot (as is the case in our example) but the
Free Tree shall keep checking, because once all snapshots that referenced the
blue blocks have disappeared, they become free blocks and can be allocated
again.
To create a new snapshot, we first have to make all changes done to the VBDs
working state as well as the Free Tree persistent by writing all corresponding
blocks to the block-device. After that, the new superblock state is written to
the block-device. To safeguard this operation, the CBE always maintains several
older states of the superblock on the block device. In case writing the new
state of the superblock fails, the CBE could fall back to the last state that,
in our example, would contain only generations 3, 4, and 5. Finally, the
current generation of the superblock in RAM is incremented by one (in the
example to generation 7). Thereby, generation 6 becomes immutable.
A question that remains is when to create snapshots. Triggering a snapshot
according to some heuristics inside the CBE might result in unnecessary
overhead. For instance, the inner nodes of the tree change frequently during a
sequential operation. We might not want them to be re-allocated all the time.
Therefore, the creation of a snapshot must be triggered explicitly from the
outside world. This way, we can accommodate different strategies, for
instance, client-triggered, time-based, or based on the amount of data
written.
When creating a snapshot, it can be specified whether it shall be disposable
or persistent. A disposable snapshot will be removed automatically by the CBE
in two situations, either
* When there are not enough usable nodes in the Free Tree left to
satisfy a write request, or
* When creating a new snapshot and all slots in the superblock that might
reference snapshots are already occupied.
A persistent snapshot, or quarantine snapshot, on the other hand will never be
removed automatically. Its removal must be requested explicitly.
During initialization, the CBE selects the most recent superblock and reads the
last generation value from it. The current generation (or working state
generation) is then set to the value incremented by one. Since all old blocks,
that are still referenced by a snapshot, are never changed again, overall
consistency is guaranteed for every generation whose superblock was stored
safely on disk.
Implementation
--------------
Although we aimed for a SPARK implementation of the CBE, we saw several
obstacles with developing it in SPARK right from the beginning. These obstacles
mainly came from the fact that none of us was experienced in designing
complex software in SPARK. So we started by conducting a rapid design-space
exploration using our mother tongue (C++) while using only language features
that can be mapped 1:1 to SPARK concepts. Additionally, we applied a clear
design methodology that allowed us to keep implementation-to-test cycles
small and perform a seamless and gradual translation into SPARK:
* _Control flow_
The core logic of the CBE is a big state machine that doesn't block. On each
external event, the state machine gets poked to update itself accordingly.
C++ can call SPARK but SPARK never calls C++. The SPARK code therefore
evolves as self-contained library.
* _Modularity_
The complex state machine of the CBE as a whole is split-up into smaller
manageable sub-state-machines, working independently from each other. These
modules don't call each other directly. Instead, an additional superior
module handles the interplay. This is done by constantly iterating over all
modules with the following procedure until no further progress can be made:
# Try to enter requests of other modules into the current one
# Poke the state machine of the current module
# The current module may have generated requests - Try to enter them into
the targeted modules
# The current module may have finished requests - Acknowledge them at the
modules they came from
Each module is represented through a class (C++) respectively a package with
a private state record (SPARK).
* _No global state_
There are no static (C++) or package (SPARK) variables. All state is kept in
members of objects (C++) respectively records (SPARK). All packages are pure
and sub-programs have no side-effects. Therefore, memory management and
communication with other components is left to OS glue-code outside the
core logic.
This approach worked out well. Module by module, we were able to translate the
C++ prototype to SPARK without long untested phases, rendering all regression
bugs manageable. In Genode, the CBE library is currently integrated through
the CBE-VFS plugin. Figure [cbe_modules] depicts its current structure and the
integration via VFS plugin.
[image cbe_modules]
The green and blue boxes each represent an Ada/SPARK package. The translation
to SPARK started at the bottom of the picture moving up to the more abstract
levels until it reached the Library module. This is the module that handles
the interplay of all other modules. Its interface is the front end of the CBE
library. So, all green packages are now completely written in SPARK and
together form the CBE library. Positioned above, the CXX library in blue is
brought in by a separate library and exports the CBE interface to C++. This
way, the CBE can also be used in other environments including pure SPARK
programs. The CXX Library package is not written in SPARK but Ada and performs
all the conversions and checks required to meet the preconditions set by the
SPARK packages below.
At the C++ side, we have the VFS plugin. Even at this level, the already
mentioned procedure applies: The plugin continuously tries to enter requests
coming from the VFS client (above) into the CBE (below), pokes the CBE state
machine, and puts thereby generated block/crypto requests of the CBE into the
corresponding back-ends (left). This process is repeated until there is no
further progress without waiting for an external event.
Current state
-------------
In its current state, the CBE library is still pretty much in flux and is not
meant for productive use.
As the Free Tree does not employ copy-on-write semantics for its meta-data, a
crash, software- or hardware-wise, will corrupt the tree structure and renders
the CBE unusable on the next start.
This issue is subject to ongoing work. That being said, there are
components that, besides being used for testing, show how the interface of the
CBE library lends itself to be integrated in components in different ways. At
the moment, there are two components making use of the CBE library as
block-device provider.
The first one is the aforementioned CBE-VFS plugin. Besides r/w access to the
working tree and r/o access to all persistent snapshots, it also provides a
management interface where persistent snapshots can be created or discarded.
Its current layout is illustrated by Figure [cbe_vfs]. The VFS plugin
generates three top directories in its root directory. The first one is the
_control_ directory. It contains several pseudo files for managing the CBE:
[image cbe_vfs]
:'key': set a key by writing a string into the file.
:'create_snapshot': writing 'true' to this file will attempt to create
a new snapshot. (Eventually the snapshot will
appear in the 'snapshots' directory if it could be
created successfully.)
:'discard_snapshot': writing a snapshot ID into this file will discard
the snapshot
The second is the 'current' directory. It gives access to the current
working tree of the CBE and contains the following file:
:'data': this file represents the virtual block device and gives
read and write access to the data stored by the CBE.
The third and last is the 'snapshots' directory. For each persistent snapshot,
there is a sub-directory named after the ID of the snapshot. This directory,
like the 'current' directory, contains a 'data' file. This file, however,
gives only read access to the data belonging to the snapshot.
The CBE-VFS plugin itself uses the VFS to access the underlying block device.
It utilizes the file specified in its configuration. Here is a '<vfs>'
snippet that shows a configured CBE-VFS plugin where the block device is
provided by the block VFS plugin.
! <vfs>
! <dir name="dev">
! <block name="block"/>
! <cbe name="cbe" block="/dev/block"/>
! </dir>
! </vfs>
An exemplary ready-to-use run script can be found in the CBE repository
at _run/cbe_vfs_snaps.run_. This run script uses a bash script to
automatically perform a few operations on the CBE using the VFS plugin.
Afterwards it will drop the user into a shell where further operations
can be performed manually, e.g.:
! dd if=/dev/zero of=/dev/cbe/current/data bs=4K
The second component is the CBE server. In contrast to the CBE-VFS plugin,
it is just a simple block-session proxy component that uses a block connection
as back end to access a block-device. It provides a front-end block session to
its client, creates disposable snapshots every few seconds, and uses the
'External_Crypto' library to encrypt the data blocks using AES-CBC-ESSIV. The
used key is a plain passphrase. The following snippet illustrates its
configuration:
! <start name="cbe">
! <resource name="RAM" quantum="4M"/>
! <provides><service name="Block"/></provides>
! <config sync_interval="5" passphrase="All your base are belong to us"/>
! </start>
The _run/cbe.run_ run script in the CBE repository showcases the use of the
CBE server.
Both run scripts will create the initial CBE state in a RAM-backed
block device that is then accessed by the CBE server or the CBE-VFS
plugin.
The run-script and the code itself can be found on the
[https://github.com/cnuke/cbe/tree/cbe_19.11 - cbe/cbe_19.11] branch on
GitHub. If you intend to try it out, you have to checkout
the corresponding
[https://github.com/cnuke/genode/tree/cbe_19.11 - genode/cbe_19.11]
branch in the Genode repository as well.
Future plans
------------
Besides addressing the current shortcomings and getting the CBE library
production-ready so that it can be used in Sculpt, there are still
a few features that are currently unimplemented. For one we would like
to add support for making it possible to resize the VBD as well as the
Free Tree. For now the geometry is fixed at initialization time and cannot
be changed afterwards. Furthermore, we would like to enable re-keying,
i.e., changing the used cryptographic key and re-encrypting the tree
set of the VBD afterwards. In addition to implementing those features, the
overall tooling for the CBE needs to be improved. E.g., there is currently
no proper initialization component. For now, we rely on a component
that was built merely as a test vehicle to generate the initial trees.
Virtualization of 64-bit ARM platforms
######################################
Genode has a long history regarding support of all kinds of
virtualization-related techniques including
[https://genode.org/documentation/release-notes/9.11#Paravirtualized_Linux_on_Genode_OKL4 - para-virtualization],
[https://genode.org/documentation/articles/trustzone - TrustZone],
hardware-assisted virtualization on
[https://genode.org/documentation/articles/arm_virtualization - ARM],
[https://genode.org/documentation/release-notes/13.02#Full_virtualization_on_NOVA_x86 - x86],
up to the full virtualization stack of
[https://genode.org/documentation/release-notes/14.02#VirtualBox_on_top_of_the_NOVA_microhypervisor - VirtualBox].
We regard those techniques as welcome stop-gap solutions for using non-trivial
existing software stacks on top of Genode's clean-slate OS architecture. The
[https://genode.org/documentation/release-notes/19.05#Kernel-agnostic_virtual-machine_monitors - recent]
introduction of a kernel-agnostic interface to control virtual machines (VM)
ushered a new level for the construction respectively porting of
virtual-machine monitors (VMM). By introducing a new ARMv8-compliant VMM
developed from scratch, we continue this line of work.
The new VMM builds upon our existing proof-of-concept (PoC) implementation for
ARMv7 as introduced in release
[https://genode.org/documentation/release-notes/15.02#Virtualization_on_ARM - 15.02].
In contrast to the former PoC implementation, however, it aims to be complete
to a greater extent. Currently, it comprises device models for the following
virtual hardware:
* RAM
* System Bus
* CPU
* Generic Interrupt Controller v2 and v3
* Generic Timer
* PL011 UART (limited)
* Pass-through devices
The VMM is able to load diverse 64-bit Linux kernels including
Device-Tree-Binary (DTB) and Initramfs. Currently, the implementation uses a
fixed memory layout for the guest-physical memory view, which needs to be
reflected by the DTB used by the guest OS. An example device-tree source file
can be found at _repos/os/src/server/vmm/spec/arm_v8/virt.dts_. The actual VMM
is located in the same directory.
Although support for multi-core VMs is already considered internally, it is
not yet finished. Further outstanding features that are already in development
are Virtio device model support for networking and console. As the first - and
by now only - back end, we tied the VMM to the ARMv8 broadened Kernel-agnostic
VM-session interface as implemented by Genode's custom base-hw kernel. As a
side effect of this work, we consolidated the generic VM session interface
slightly. The RPC call to create a new virtual-CPU now returns an identifier
for identification.
The VMM has a strict dependency on ARM's hardware virtualization support
(EL2), which comprises extensions for the ARMv8-A CPU, ARM's generic timer,
and ARM's GIC. This rules out the Raspberry Pi 3 board as a base platform
because it does not include a GIC but a custom interrupt-controller without
hardware-assisted virtualization of interrupts. To give the new VMM a try, we
recommend using the run script _repos/os/run/vmm_arm.run_ as a starting point
for executing the VMM on top of the i.MX8 Evaluation Kit board.
New tooling for bridging existing build systems with Genode
###########################################################
Genode's development tools are powerful and intimidating at the same time.
Being designed from the perspective of a whole-systems developer, they put
emphasis on the modularity of the code base (separating concerns like
different kernels or system abstraction levels), transitive dependency
tracking between libraries, scripting of a wide variety of system-integration
tasks, and the continuous integration of complete Genode-based
operating-system scenarios. Those tools are a two-edged sword though.
On the one hand, the tools are key for the productivity of seasoned Genode
developers once the potential of the tools is fully understood and leveraged.
For example, during the development of Sculpt OS, we are able to
change an arbitrary line of code in any system component and can test-drive
the resulting Sculpt system on real hardware within a couple of seconds.
As another example, the almost seamless switching from one OS kernel to
another has become a daily routine that we just take for granted without
even thinking about it.
On the other hand, the sophistication of the tools stands in the way of
application developers who are focused on a particular component instead
of the holistic Genode system. In this case, the powerful system-integration
features remain unused but the complexity of the tools and the build system
prevails. Speaking of build systems, this topic is ripe of emotions
anyway. _Developers use to hate build systems._ Forcing Genode's build
system down the throats of application developers is probably not the best
idea to make Genode popular.
This line of thoughts prompted us to re-approach the tooling for Genode from
the perspective of an application developer. The intermediate result is a new
tool called Goa:
:Goa project at GitHub:
[https://github.com/nfeske/goa]
Unlike Genode's regular tools, Goa's work flow is project-centered. A project
is a directory that may contain source code, data, instructions how to
download source codes from a 3rd party, descriptions of system scenarios, or
combinations thereof. Goa is independent from Genode's regular build system.
It combines Genode's package management (depot) with commodity build systems
such a CMake. In addition to building and test-driving application software
directly on a Linux-based development system, Goa is able to aid the process
of exporting and packaging the software in the format expected by Genode
systems like Sculpt OS.
At the current stage, Goa should be considered as work in progress. It's a new
approach and its success is anything but proven. That said, if you are
interested in developing or porting application software for Genode, your
feedback would be especially valuable. As a starting point, you may find the
following introductory article helpful:

Base framework and OS-level infrastructure
##########################################
File-system session
===================
The file-system session interface received a much anticipated update.
Writing modification times
--------------------------
The new operation WRITE_TIMESTAMP allows a client to update the modification
time of a file-system node. The time is defined by the client to keep
file-system servers free from time-related concerns. The VFS server implements
the operation by forwarding it to the VFS plugin interface. At present, this
new interface is implemented by the rump VFS plugin to store modification
times on EXT2 file systems.
Enhanced file-status info
-------------------------
The status of a file-system node as returned by the 'File_system::Status'
operation has been revisited. First, we replaced the fairly opaque "mode" bits -
which were an ad-hoc attempt to stay compatible with Unix - with the explicit
notion of 'readable', 'writeable', and 'executable' attributes. We completely
dropped the notion of users and groups. Second, we added the distinction
between *continuous* and *transactional* files to allow for the robust
implementation of continuous write operations across component boundaries. A
continuous file can be written-to via a sequence of arbitrarily sized chunks
of data. For such files, a client can split a large write operation into any
number of smaller operations in accordance to the size of the used I/O
buffers. In contrast, a write to a transactional file is regarded as a
distinct operation. The canonical example of a transactional file is a
socket-control pseudo file.
Virtual file-system infrastructure
==================================
First fragments of a front-end API
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The VFS is mostly used indirectly via the C runtime. However, it is also
useful for a few components that use the Genode API directly without any
libc. To accommodate such users of the VFS, we introduced the front-end
API at _os/vfs.h_ that covers a variety of current use cases. Currently, those
use cases revolve around the watching, reading, and parsing of files and
file-system structures - as performed by Sculpt's deployment mechanism.
Writing to files is not covered.
Improved file-watching support
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
All pseudo files that use the VFS-internal 'Readonly_value_file_system'
utility have become able to deliver watch notifications. This change enables
VFS clients to respond to VFS-plugin events (think of terminal resize)
dynamically.
Speaking of the *terminal VFS plugin*, the current release enhances the plugin
in several respects. First, it now delivers status information such as the
terminal size via pseudo files. Second, we equipped the VFS terminal file
system with the ability to detect user interrupts in the incoming data stream,
and propagate this information via the new pseudo file '.terminal/interrupts'.
Each time, the user presses control-c in the terminal, the value stored in
this pseudo file is increased. Thereby, a VFS client can watch this file to
get notified about the occurrences of user interrupts.
VFS plugin for emulating POSIX pipes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We added a new VFS plugin for emulating POSIX pipes. The new plugin creates
pipes between pairs of VFS handles. It replaces the deprecated libc_pipe
plugin. In contrast to the libc_pipe plugin, which was limited to pipes within
one component, the new VFS plugin can also be used to establish pipes between
different components by mounting the plugin at a shared VFS server.
C runtime with improved POSIX compatibility
===========================================
Within Genode, we used to think of POSIX as a legacy that is best avoided.
In fact, the foundational components of the framework do not depend on a
C runtime at all. However, higher up the software stack - at the latest when
3rd-party libraries enter the picture - a working C runtime is unavoidable. In
this statement, the term "working" is rather muddy though. Since we have never
fully embraced POSIX, we were content with cutting corners here and there. For
example, given Genode's architecture, supporting 'fork' and 'execve' seemed
totally out of question because those mechanisms would go against the grain of
Genode.
However, our growing aspiration to bridge the gap between existing popular
applications and Genode made us re-evaluate our stance towards POSIX.
All technical criticism aside, POSIX is immensely useful because it is
a universally accepted stable interface. To dissolve friction between
Genode and popular application software, we have to satisfy the application's
expectations. This ignited a series of developments, in particular
the added support for 'fork' and 'execve' - of all things - in
[https://genode.org/documentation/release-notes/19.08#Consolidation_of_the_C_runtime_and_Noux - Genode 19.08],
which was nothing short of surprising, even to us.
The current release continues this line of development and brings the
following improvements.
Execve
------
The libc's 'execve' implementation got enhanced to evaluate the path of the
executable binary according to the information found on the VFS, in particular
by traversing directories and following symbolic links. This enables the libc
to execute files stored at sub directories of the file system.
Furthermore, 'execve' received handling for *executing shell scripts* by
parsing the shebang marker at the beginning of the executable file. This way,
the 'execve' mechanism of the libc reaches parity with the feature set of the
Noux runtime that we traditionally used to host Unix software on top of
Genode.
Modification-time handling
--------------------------
By default, the libc uses the just added facility for updating the timestamp
of file-system nodes when closing a written-to file, which clears the path
towards using tools like 'make' that rely on file-modifications times.
The libc's mechanism can be explicitly disabled by specifying
! <libc update_mtime="no"...>
This is useful for applications that have no legitimate access to a time
source.
Emulation of 'ioctl' operations via pseudo files
------------------------------------------------
With the current release, we introduce a new scheme of handling ioctl
operations, which maps 'ioctl' calls to pseudo-file accesses, similar to how
the libc already maps socket calls to socket-fs operations.
A device file can be accompanied with a (hidden) directory that is named after
the device file and hosts pseudo files for triggering the various device
operations. For example, for accessing a terminal, the directory structure
looks like this:
! /dev/terminal
! /dev/.terminal/info
! /dev/.terminal/rows
! /dev/.terminal/columns
! /dev/.terminal/interrupts
The 'info' file contains device information in XML format. The type of the XML
node corresponds to the device type. Whenever the libc receives a TIOCGWINSZ
ioctl for _/dev/terminal_, it reads the content of _/dev/.terminal/info_ to
obtain the terminal-size information. In this case, the _info_ file looks as
follows:
! <terminal rows="25" columns="80/>
Following this scheme, VFS plugins can support ioctl operations by providing
an ioctl directory in addition to the actual device file.
Emulation of POSIX signals
--------------------------
Even though there is no notion of POSIX signals at the Genode level, we
can reasonably emulate certain POSIX signals at the libc level. The current
release introduces the first bunch of such emulated signals:
:SIGWINCH: If 'stdout' is connected to a terminal, the libc watches the
terminal's ioctl pseudo file _.terminal/info_. Whenever the terminal
size changes, the POSIX signal SIGWINCH is delivered to the application.
With this improvement, Vim becomes able to dynamically adjust itself
to changed window dimensions when started as a native Genode component
(w/o the Noux runtime environment).
:SIGINT: If 'stdin' is connected to a terminal, the libc watches the
terminal's pseudo file _.terminal/interrupts_. Since, the terminal VFS
plugin modifies the file for each occurred user interrupt (control-c),
the libc is able to reflect such an event as SIGINT signal to the
application.
:Process-local signal delivery: The libc's implementation of 'kill' got
enhanced with the ability to submit signals to the local process.
Support for arbitrarily large write operations
----------------------------------------------
The number of bytes written by a single 'write' call used to be constrained by
the file's underlying I/O buffer size. Even though our libc correctly returned
this information to the application, we found that real-world applications
rarely check the return value of 'write' because partial writes do usually not
occur on popular POSIX systems. Thanks to the added distinction between
continuous and transactional files as described in Section
[File-system session], we became able to improve the libc's write operation to
iterate on partial writes to continuous files until the original write count
is reached. The split of large write operations into small partial writes as
dictated by the VFS infrastructure becomes invisible to the libc-using
application.
Input-event handling
====================
In Genode 19.08, we undertook a comprehensive rework of our keyboard-event
handling in the light of localization and also promised to tie up remaining
loose ends soon.
First, we again dived into our character generators for a thorough check of
our stack of keyboards and fixed remaining inconsistencies in French and
German layouts. En passant, we also increased the default RAM quotas for
the input filter to 1280K in our recipes to cope with the increased
layout-configuration sizes in corner cases.
Next - and more importantly - we subdued the monsters lurking in our Qt5
keyboard back end and enabled transparent support for system-wide keyboard
layout configuration for Qt5 components. One important change during this work
was to move the handling of control key sequences into the clients. For
example, the graphical terminal and Qt5 interpret key events in combination
with the CTRL modifier based on characters and, thus, support CTRL-A with
AZERTY and QWERTY layouts correctly. As a result we removed all CTRL modifier
(mod2) configurations from our character-generator configurations.
Finally we'd like to point out one important change of our rework that
repeatedly led to surprises: For keys without character mappings the reworked
character-generator mechanism emits invalid codepoints in contrast to
codepoints with value 0. For that reason, components interpreting character
events should check 'Codepoint::valid()' to prevent the processing of invalid
characters (and not the frequent pattern of 'codepoint.value != 0').
NIC router
==========
The NIC router has received the ability to report the link state of its NIC
interfaces (downlinks and uplinks). To control this mechanism, there are two
new boolean attributes 'link_state' and 'link_state_triggers' in the <report>
tag of the NIC router configuration. If the former is set to "true", the report
will contain the current link state for each interface:
! <domain name="domain1">
! <interface label="uplink1" link_state="false"/>
! <interface label="downlink1" link_state="true"/>
! </domain>
! <domain name="domain2">
! <interface label="downlink2" link_state="true"/>
! </domain>
The second attribute decides whether to trigger a report update each time the
link state of an interface changes. By default, both attributes are set to
"false".
Device drivers
==============
Platform driver on x86
~~~~~~~~~~~~~~~~~~~~~~
During our enablement of Genode on a
[https://genodians.org/chelmuth/2019-10-21-sculpt-elitebook - recent notebook],
we spotted some PC platform shortcomings, we address with this release. Most
prominently we added support for
[https://en.wikipedia.org/wiki/PCI_configuration_space#Bus_enumeration - 64-bit PCI base address registers]
to the x86 platform driver. This allows the use of PCI devices that are
assigned to physical I/O-memory regions beyond 4 GiB by the boot firmware.
Wireless driver
~~~~~~~~~~~~~~~
We added the firmware images for the 5000 and 9000 series of Intel wireless
devices to the firmware white-list in the _wifi_drv_ component. Such devices
as 5100AGN, 5300AGN and 5350AGN as well as 9461, 9462 and 9560 should now be
usable on Genode.
Libraries and applications
##########################
VirtualBox improvements
=======================
The GUI handling of our VirtualBox port got improved to react on window-size
changes more instantly. The effect is that an interactive adjustment of the
window size, e.g., on Sculpt, becomes quickly visible to the user. Still, the
VM may take some time to adjust to the resolution change, which ultimately
depends on the behavior of the driver of the VirtualBox guest additions.
Updated 3rd-party software
==========================
With the addition of the 64-bit ARM architecture (AARCH64) with the
[https://genode.org/documentation/release-notes/19.05#Broadened_CPU_architecture_support_and_updated_tool_chain - 19.05]
release, it became necessary to update the libraries the Genode tool chain
(gcc) depends on in order to support AARCH64 properly. This concerns the GNU
multi precision arithmetic library (gmp), which has been updated from version
4.3.2 to 6.1.2, as well as the libraries that depend on it: Multi precision
floating point (mpfr) and multi precision complex arithmetic (mpc). All those
old versions did not offer support for the AARCH64 architecture, which is a
requirement to make Genode self hosting. Targets for building binutils and GCC
within Genode for AARCH64 are in place, GNU make is in place, and even code
coverage (gcov) has been added. This work puts AARCH64 in line with other
supported CPU architectures and emphasizes our interest in the ARM 64-bit
architecture.
Platforms
#########
Execution on bare hardware (base-hw)
====================================
With the previous release, Genode's base-hw kernel got extended to support the
ARMv8-A architecture in principle. The first hardware supported was the
Raspberry Pi 3 as well as the i.MX8 evaluation kit (EVK). But only a single
CPU-core was usable at that time. Now, we lifted this limitation. On both
boards, all four CPU-cores are available henceforth.
Removed components
##################
The current release removes the following components:
:gems/src/app/launcher:
The graphical launcher remained unused for a few years now. It is not
suitable for systems as flexible as Sculpt OS.
:os/src/app/cli_monitor:
CLI monitor was a runtime environment with a custom command-line interface
to start and stop subsystems. It was part of the user interface of our
first take on a Genode-based desktop OS called
[https://genode.org/documentation/release-notes/15.11#Genode_as_desktop_OS - Turmvilla].
Nowadays, we use standard command-line tools like Vim to edit init
configurations dynamically, which is more flexible and - at the same time -
alleviates the need for a custom CLI. The CLI-monitor component was too
limited for use cases like Sculpt anyway.
Along with the CLI monitor, we removed the ancient (and untested for long
time) _terminal_mux.run_ script, which was the only remaining user of the CLI
monitor.
:fatfs_fs, rump_fs, and libc_fatfs plugin:
The stand-alone file-system servers fatfs_fs and rump_fs as well as the
fatfs libc plugin have been superseded by the fatfs and rump VFS plugins.
The stand-alone servers can be replaced by using the VFS server plus the
corresponding VFS plugin as a drop-in replacement.

Background information - Why do we need a special tool chain?
#############################################################
Early on in the genesis of Genode, we introduced a custom tool chain to
overcome several problems inherent to the use of standard tool chains installed
on Linux host platforms.
First, GCC and binutils versions vary a lot between different Linux systems.
Testing the Genode code with all those different tool chains and constantly
adapting the code to the peculiarities of certain tool-chain versions is
infeasible and annoying. Second, Linux tool chains use certain features that
stand in the way when building low-level system components. For example, the
'-fstack-protector' option is enabled by default on some Linux distributions.
Hence, we have to turn it off when building Genode. However, some tool chains
lack this option. So the attempt to turn it off produces an error. The most
important problem with Linux tool chains is the dependency of their respective
GCC support libraries on the glibc. When not using a Linux glibc, as the case
with Genode, this leads to manifold problems, most of them subtle and extremely
hard to debug. For example, the support libraries expect the Linux way of
implementing thread-local storage (using segment registers on x86_32). This
code will simply crash on other kernels. Another example is the use of certain
C-library functions, which are not available on Genode. Hence, Genode provides
custom implementations of those functions (in the 'cxx' library).
Unfortunately, the set of functions used varies across tool-chain versions. For
these reasons, we introduced a custom configured tool chain where we mitigated
those problems by pinning the tools to certain versions and tweaking the
compiler configuration to our needs (i.e., preventing the use of Linux TLS).
That said, the use a our custom configured tool chain was not free from
problems either. In particular, the script for creating the tool chain relied
on a libc being present on the host system. The header files of the libc would
be used to build the GCC support libraries. This introduced two problems. When
adding Genode's libc to the picture, which is based on FreeBSD's C library, the
expectations of the GCC support libraries did not match 100% with the semantics
implemented by Genode's libc (e.g., the handling of 'errno' differs). The
second problem is the limitation that the tool chain could only be built for
the platform that corresponds to the host. For example, on a Linux-x86_32
system, it was not possible to build a x86_64 or ARM tool chain. For this
reason we used the ARM tool chains provided by CodeSourcery.
With Genode 11.11, we addressed the root of the tool-chain problem by
completely decoupling the Genode tool chain from the host system that is used
to build it. The most important step was the removal of GCC's dependency on
a C library, which is normally needed to build the GCC support libraries. We
were able to remove the libc dependency by sneaking-in a small custom libc stub
into the GCC build process. This stub comes in the form of the single header
file 'tool/libgcc_libc_stub.h' and brings along all type definitions and
function declarations expected by the support-library code. Furthermore, we
removed all GNU-specific heuristics from the tool chain. Technically, the
Genode tool chain is a bare-metal tool chain. But in contrast to existing
bare-metal tool chains, C++ is fully supported.
With the libc dependency out of the way, we are now free to build the tool
chain for arbitrary architectures, which brings us two immediate benefits. We
do no longer have to rely on the CodeSourcery tool chain for ARM. There is now
a 'genode-arm' tool chain using the same compiler configuration as used on x86.
The second benefit is the use of multiarch libs on the x86 platform. The
genode-x86 tool chain can be used for both x86_32 and x86_64 as build target,
the latter being the default.
Since we introduced GDB support into Genode, we added GDB in addition to GCC
and binutils to the Genode tool chain. The version is supposed to match the one
expected by Genode's GDB facility, avoiding potential problems with mismatching
protocols between GDB monitor and GDB.

Subject: [PATCH 02/15] FOC: change l4_task_cap_equal semantic
The syscall l4_task_cap_equal almost returns false although the referenced
kernel-objects are equal. This patch changes the semantic of the syscall so that
whenever two capabilities refering the same kernel-object are compared it will
return true. Please refer to the discussion of the following mail thread:
http://www.mail-archive.com/l4-hackers@os.inf.tu-dresden.de/msg05162.html

Subject: [PATCH 03/15] Sigma0: raise sigma0's priority to maximum.
When sigma0 runs on a lower priority than the rest of the threads in the system
it might come to the point that while answering a page fault or I/O memory area
request the timeslice of the caller (core-pager) gets fully consumed. As long as
other threads are still executable and don't block sigma0 won't do progress
anymore, because it runs at the lowest priority. This commit simply sets
sigma0's priority to the highest in the system.

With this patch the comport are tried to read out from the BIOS Data Area
on x86 machines. The BDA Area are part of the first physical page and may
contain the non-default io ports of the comport.
When used together with 'bender' from the 'morbo' toolchain, even serial PCI
cards (also Intel's AMT Serial Over Line adapter) are detected automatically.
