This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.
Fixes#3208
As a preparatory step for introducing the new block-client API, we have
to turn the 'Block::Connection' into a class template. The template
argument will be used to tie an application-defined job type to the
block connection.
Issue #3283
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.
Fixes#3274
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).
Issue #3274
This patch modernizes the 'Block::Session::info' interface. Instead of
using out parameters, the 'init' RPC function returns a compound 'Info'
object now. The rather complicated 'Operations' struct is replaced by
a 'writeable' attribute in the 'Info' object.
Fixes#3275
This patch removes the reliance of the extract tool from the libc's
behavior regarding the access of time and timing.
The extract tool is not expected to need time. However, unfortunately,
libarchive calls the 'time' function unconditionally. By adding a
dummy for 'time', we avoid bothering the libc, which would otherwise
need to obtain a time source.
Issue #3204
In the original version, I used 'number_of_bits' because Ada's 'Size
returns the size in bits, not bytes. But the values (for objects) are
always a multiple of 8. On the C++ side, performing size checks at the
granularity of bits is just awkward. The term 'object size' is more
natural.
By adding a wildcard at the beginning of (expected) error messages, the
test.run tool becomes able to match the lines (ignoring the characters
of the color escape sequence).
The "nameserver" file cannot be opened through a VFS File_system client
if the plugin does not support opening the parent directory of
"/nameserver", which would be "/".

Replace the I/O response handler that is passed to the VFS at
construction with an object that is dynamically attached to handles.
This object shall also accept read-ready notifications, and plugins are
encouraged to keep handles awaiting ready-ready notifications separate
from handles that await I/O progress.
Replace the use of handle lists in plugins with handle queues, this
makes the code easier to understand and the ordering of notifications to
the application more explicit.
These changes replace the use of the Post_signal_hook from all VFS
plugins, applications must assume that read-ready and I/O notifications
occur during I/O signal dispatch and use an Io_progress_handler at its
entrypoints to defer response until after signal dispatching.
Fix#3257
Make sure that the rwlock is allocated before a lock operation is
performed. This case occurs if a static rwlock was create by using
PTHREAD_RWLOCK_INITIALIZER. Same goes for PTHREAD_CONDS_INITIALIZER.
Fixes#3262.
For better or worse we have no proper way of handling this right now
but contrib libraries, e.g. glib, use it to determine if they can use
the underlying fd.
Fxies #3265.
The new configuration attributes <tcp-forward to_port="123" /> and
<udp-forward to_port="123" /> enable manipulating the destination port of
port-forwarded packets.
Fixes#3237
The "Vfs::Vfs_handle" type should not contain any public members that
can be initialized by the VFS internally and by the application, so
remove inheritance from the "Genode::list::Element" class. The VFS
plugins must instead use lists of "Vfs::Vfs_handle" sub-classes, the
lifetime of which are always managed by the plugin.

This is a follow-up commit to "Update <provides> info in pkg runtimes",
which adapts the users of the wm pkg to the changed label of the "focus"
nitpicker session.
bus or device should be different (not both) when comparing a device to
already present devices. Because of this the second USB device was
marked as existent when the bus matched or the bus did not but the
device number.
The site download.qt.io seems to apply some mirror-via-HTTP-redirect
scheme which, unfortunately, seems broken (and therefore annoyingly
slow) for non-SSL-secured URLs.
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.
