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.

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.

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.
Also remove 'requires_installation_of', while also checking sbin
directories in 'have_installed'. The run scripts have been adjusted
accordingly.
Fixes#2853
The 200-second timeout of the init test triggers on some test platform
(in particular on qemu) while it is overly pessimistic on others.
This patch aims at stabilizing the timing behavior of the test across
the tested kernels/machines.
This is a follow-up patch of "init: avoid too eager child restart". On
each config update of init, init re-applies child-specific configuration
changes. In the case of an already exited child, this re-evaluation
wrongly marked such a child as abandoned because the child's environment
sessions do no longer exist. Abandoning the child, in turn, triggers the
destruction and subseqent restart (because the <start> node of the
configuration still exists). The latter is bad for two reasons.
First, the exit state of the original instance becomes lost. Second, the
restart may have unexpected side effects due to sessions created by the
new instance. I.e., when resizing a partition in sculpt, init would
wrongly restart the gpt-write tool after the tool successfully exited.
This collides with a newly started instance of part_blk/resize2fs, which
now competes with the second gpt-write instance for the exclusive access
of the targeted block device.
The patch prevents init from re-applying configurations to exited
children. The accompanied test case covers the corner case.
Do not simply wait for the good ping test to finish, but for the other
flood tests to trigger the RAM exhaustion. This makes the test more
robust with slower platforms or a different timing.
Issue #2857
The log messages covered by verbose_packet_drop were previously
configured by the verbose attribute. This isn't the case anymore. Now,
you can configure them as follows:
! <config verbose_packet_drop="no" ... >
! <domain verbose_packet_drop="no" ... />
! <config/>
The new attribute determines whether to log each packet drop and the
rational behind it. The <config> value affects all domains without a
<domain> local value.
Issue #2857
The default value of each <domain> is the <config> value. However, if
a <domain> local value is set, the <config> value doesn't affect this
value at all.
Fixes#2874
The ICMP-Echo-server functionality of the router has the following
configuration attributes (default values shown):
! <config icmp_echo_server="yes">
! <domain icmp_echo_server="yes" ... />
! </config>
The icmp_echo_server attribute configures whether the router answers ICMP Echo
requests that address the router. The <config> value affects all domains
without a <domain> local value.
Issue #2874
This patch ensures that session-create requests are handled after close
requests, which solves the corner case where one single-session server
receives a close and create request at the same time. E.g., when
expanding a partition with Sculpt, the gpt-write tool is removed and
part_blk is started (to execute resize2fs on top) in one step. Both
interact with the USB-block driver, which is a single-session server.
Fixes#2877

- avoid GP when switching on AMD SVM if disabled by UEFI/BIOS
Issue #2854
When a domain is updated to a new component config, the two criteria for
keeping an ARP waiting state of a remote domain are whether the remote
domain still exists and whether its IP config is still the same. This
means that a domain must also dissolve all of its remote ARP waiting
states if its IP config changes (without an update of the component
config). This wasn't the case until now.
Issue #2840
The top-level Sculpt configuration is routing ROM requests for chargen
files from the input_filter to the parent, and this prevents new chargen
files to specified, for instance the German or Workman layout. Route ROM
requests with a combination of label_prefix and label_suffix patterns to
the config_fs_rom component, allowing the input_filter to be dynamically
reconfigurable.
