Several nightly network-related tests fail currently on sel4/pc because the
new e1000 NIC driver requires more capabilities. The "drivers nic" package
was already adapted to the new requirement but some tests fail to provide
enough caps to the corresponding sub system. This commit tries to fix all
remaining tests.
Ref #4923
Since the wireless LAN driver is actually a 'Libc::Component' due to
its incorporation of the 'wpa_spplicant' application, we have to
intercept its construction because we have to initialize the Lx_kit
environment before any static ctors are executed. Most Linux initcalls
are implemented as ctors that will be otherwise implicitly executed
before the controll is given to us in 'Libc::Component::construct'.
Issue #4927.
This commit changes the firmware handling from requesting each
firmware file as a ROM module that is checked against a list of
known images (including their size) to requesting each file via
the local VFS of the 'wifi_drv'. This allows for using the original
probing mechanism that tries to select a matching firmware version.
The 'repos/dde_linux/src/drivers/wifi/README' file contains more
detailed information on how to configure the driver.
Issue #4861.
The bulk of the driver code now lives in the 'dde_linux' repository,
which is available on all platforms, from where it can be referenced by
other repositories.
The 'wifi_drv' binary was delegated to a generic harness that includes
all configuration and management functionality shared by all wireless
device driver components, e.g., the wpa_supplicant. The code of the
device driver emulation environment is located in 'src/lib/wifi'. It
is referenced by the platform-specific driver library that resides in
the corresponding platform repository. The runtime configuration needs
to point the driver to proper driver library.
The platform-specific library is in charge of orchestrating the contrib
source utilized by the driver as well as providing the 'source.list'
and 'dep.list' files. It must include the generic library snippet
'repos/dde_linux/lib/wifi.inc' that deals with managing the emulation
environment code.
The 'repos/dde_linux/src/drivers/wifi/README' file contains more
detailed information on how to deploy the driver.

* use netperf omnitest output selectors to acquire more metrics

Note, OpenSSL now comes as one combined depot archive *openssl* that
replaces the former *libssl* and *libcrypto* archives. The libraries are
still separate binaries for compatibility with legacy software.
Issue #3773
It seems that with the nigthly autopilot the data port (that is choosen by the
client) may stay some time (minutes) allocated after the a test run. This
causes successive tests to fail when trying to reuse the port.
* Use a unique data port for each target platform in the range of 18000-18099.
* Add documentation on how to prepare for running the test on a Linux target.
* Remove Qemu-specific code paths as Qemu isn't supported anymore by the script
since the introduction of the Uplink session (running with a NIC router on
Qemu was never supported and now we always need a NIC router).
Ref #3961
* Remove SPEC declarations from mk/spec
* Remove all board-specific REQUIRE declaratiions left
* Replace [have_spec <board>] run-script declarations with have_board where necessary
* Remove addition of BOARD variable to SPECS in toplevel Makefile
* Move board-specific directories in base-hw out of specs
Let the NIC router provide an Uplink service besides the Nic service that it
already provided. Requests for an Uplink session towards the NIC router are
assigned to Domains using the same <policy> configuration tags that are used in
order to assign Nic session requests. The MAC addresses of Uplink session
components are _NOT_ considered during the allocation of MAC addresses for NIC
session components at the same Domain. The task of avoiding MAC address clashes
between Uplink session components and Nic session components is therefore left
to the integrator. Apart from that, Uplink session components are treated by
the NIC router like any other interface.
Ref #3961
Right now the same code dealing with nic setup on qemu is duplicated
in many different run scripts. It makes it unnecesarily complex to
change the existing config or add support for new nic types. Lets move
all this common code to qemu.inc.
Ref #3825
Introduce the managing_system privilege for components like the
platform_driver to allow it to call system management functionality
that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware.
The former RAM resource configuration attribute `constrain_phys`,
which enabled to constrain the region of physical RAM to be used,
gets replaced by the new, broader managing_system configuration
attribute of a `start` node. It gets enforced by the sandbox library.
Ref #3816
This patch removes old 'Allocator_guard' utility and replaces its use
with the modern 'Constrained_ram_allocator'.
The adjustment of core in this respect has the side effect of a more
accurate capability accounting in core's CPU, TRACE, and RM services.
In particular, the dataspace capabilities needed for core-internal
allocations via the 'Sliced_heap' are accounted to the client now.
The same goes for nitpicker and nic_dump as other former users of the
allocator guard. Hence, the patch also touches code at the client and
server sides related to these services.
The only remaining user of the 'Allocator_guard' is the Intel GPU
driver. As the adaptation of this component would be too invasive
without testing, this patch leaves this component unchanged by keeping a
copy of the 'allocator_guard.h' locally at the component.
Fixes#3750
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.
Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.
Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.
Issue #3101
This patch reintroduces the LwIP stack to libc as a VFS plugin
implementing the socket_fs interface. Rather than use LwIP's socket
emulation layer this plugin interfaces directly to LwIP raw API and is
single threaded.
The internal TCP parameters of the stack are untuned.
Fix#2050Fix#2335
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
Introduce the uplink tag:
! <config>
! <uplink label="wifi" domain="uplink">
! <uplink label="wired" domain="wired_bridge">
! <uplink domain="wired_bridge">
! <config/>
For each uplink tag, the NIC router requests a NIC session with the
corresponding label or an empty label if there is no label attribute.
These NIC sessions get attached to the domain that is set in their
uplink tag as soon as the domain appears. This means their lifetime is
not bound to the domain. Uplink NIC sessions can be safely moved from
one domain to another without being closed by reconfiguring the
corresponding domain attribute.
Attention: This may render previously valid NIC router configurations
useless. A domain named "uplink" doesn't automatically request a NIC
session anymore. To fix these configurations, just add
! <uplink domain="uplink"/>
or
! <uplink label="[LABEL]" domain="uplink"/>
as direct subtag of the <config> tag.
