The ram plugin to the VFS must send notifications to watch handles on
files when they are removed. This brings the VFS server to parity with
the ram_fs server for the sake of notifications.
Move run/fs_report to gems and use the vfs server and the vfs init
plugin in the test.
Ref #2902
This patch removes the detection of statically linked executables from
the base framework. It thereby fixes the corner cases encountered with
Sculpt when obtaining the binaries of the runtime from the depot_rom
service that is hosted within the runtime.
Statically linked binaries and hybrid Linux/Genode (lx_hybrid) binaries
can still be started by relabeling the ROM-session route of "ld.lib.so"
to the binary name, pretending that the binary is the dynamic linker.
This can be achieved via init's label rewriting mechanism:
<route>
<service name="ROM" unscoped_label="ld.lib.so">
<parent label="test-platform"/> </service>
</route>
However, as this is quite cryptic and would need to be applied for all
lx_hybrid components, the patch adds a shortcut to init's configuration.
One can simply add the 'ld="no"' attribute to the <start> node of the
corresponding component:
<start name="test-platform" ld="no"/>
Fixes#2866
When mounting a ROM module with binary="no", the
vfs will detect the 0-termination to calculate the
file size instead of using the dataspace size.
Fixes#2903
Process I/O packets in batches. If a batch is processed and there are
still packets pending, send a signal locally to the packet handler and
return to the entrypoint signal dispatcher. This prevents clients from
starving each other, which happens when a client continuously submits
packets at a faster rate than the server can process.
Fix#2900
Test of File_system I/O scheduling. It appears that a client not
submitting I/O packets slower than the VFS server can process will
starve other clients.
Ref #2900
This patch adds the /config/usb file to Sculpt, which allows then user
to manually define rules for assigning USB devices to clients. The
content is incorporated by the driver manager into the USB driver
configuration. Note that this mechanism does not work for HID devices
because these devices are claimed by the USB driver's built-in HID
support.
Issue #2890
Previously, the trace control of a thread was initialized in its
constructor (which is generic for all components). This has the
disadvantage that the CPU-session-pointer member of the thread might not
be valid at this point. And it cannot be replaced by using the
"deprecated_env" CPU session neither as constructing the deprecated
environment in causes troubles in Core. But as the trace control
shouldn't be needed in Core anyway, the initialization can be moved to
the Thread::start implementation of non-core components. This code
already takes care of the CPU session pointer.
Fixes#2901
This component is contrasted with the fs_rom server that serves
independent dataspaces to each client. Using a cache was not possible
until the region map session supported the creation of read-only
attachments.
Test at run/read_only_rom.

The verbosity mode of the NIC bridge can be toggled with the verbose attribute
(default value shown):
! <config verbose="no" />
If enabled, the NIC bridge logs sent and received packets as well as the
lifetime of interfaces connected to the bridge.
Issue #2899
This commit contains a patch of bash's built-in default escape sequences
to match the 'screen' terminal as used by Genode's terminal component.
Fixes#2705
The test triggers the following assertion in the kernel, which will
remain unfixed as the kernel is no longer developed:
Assertion queue_state.is_set(queue_state_t::send) failed in file
.../pistachio/kernel/src/api/v4/tcb.h, line 727
This assertion is presumably similar / related to issue #1495.
Do not generate invalid configurations for the uplink domain anymore. If
some tests are disabled and therefore their routing rules at the uplink
domain would be invalid, spare out these routing rules.
Issue #2899
This patch addresses a corner case revealed by the resource_request test
on seL4 after changing the child-destruction handling with commit "base:
close PD on 'close_all_sessions'". During the destruction of the PD
session, the backing store (session-local RAM dataspace factory) of the
signal broker's slab was destroyed before destructing the signal broker.
Instantiating the signal broker after the RAM dataspace factory fixes
the destruction order.
Quietly insert forward declaration of a Input::Binding class, and make
it a friend of Input::Event and Input::Session_client. This is to allow
non-C++ language bindings (Nim) to access private members by providing
their own implementation of the Binding class.
Fix#2889
The legacy PIT timer driver is too jittery for the character-repeat
test. This patch disables the test for platforms using this device as
user-level time source, which are at the moment OKL4, Pistachio, and
seL4.
This patch makes the run script compatible with the disk-image backend
of the run tool. Since this backend attaches the boot image as AHCI
disk 0, we have to supply our custom disk image as AHCI 1.
The native CPU client holds a capability reference and the reference
counter of the capability can reach its limit when many threads are
successively created and destroyed (destroyed by the Linux kernel).
Fixes#2886
When first selecting an access point to connect to, and then - while the
passphrase entry field is displayed - switching to wired networking, the
keyboard focus was still referring to the passphrase entry field instead
of yieling the focus to the inspect window. This commit fixes the
problem by adding the wifi NIC target as additional condition.
This patch improves the handling of the corner case where a client
vanishes while a session request is in flight (CREATE_REQUESTED but
not yet AVAILABLE). This corner case could be sporadically observed with
the init_loop test on base-linux.
In the original version, the session would eventually be delivered but
never picked up by anyone. Such a stale session still uses resources that
should better be released. In the new version, the parent checks for the
liveliness of the client whenever a session is delivered. If there is no
client of the session, a close request is immediately issued to the
server. The session state must be preserved until the close requests has
been answered.
This patch moves the closing of a child's PD session from the 'Child'
destructor to the 'close_all_sessions' method. This way, the child's
PD quota is immediately returned as soon as init flags a child as
'abandoned', which removes jitter from init's RAM-state reports.
The patch is supposed to make the 'init_loop.run' test much happier.
This commit is a follow-up to "nit_fb: allow screen-relative
initial_width/height". With it, the nit_fb window created via the
launchpad can be interactively resized.
