When wrongly invoking the run script by specifying a skipped test
as its only TEST_PKGS argument, the run script fails due to a wrong
tar argument order. Let's better reflect this condition to the user
ahead of invoking tar.
This patch modifies the mixer's time window allocation by modelling the
drift of the period length over time. This yields a much better
stability of the detected sample rates in the presence of jitter.

- New session interfaces:
- os/include/play_session (for audio playing / mic-input driver)
- os/include/record_session (for audio recording / audio-output driver)
- Mixer at os/src/record_play_mixer providing both play and record services
- Simple waveform player at os/src/app/waveform_player
- Simple audio-signal capturing component at os/src/app/record_rom
- Simple oscilloscpe at gems/src/app/rom_osci (using record_rom)
- Simple test-audio_play for playing raw stereo f32 data
The _gems/run/waveform_player.run_ script illustrates the use of the new
components and interfaces.

This change allows for the hosting of system-management components
in Sculpt's runtime. The special role must be declared either as
<launcher managing_system="yes"> attribute or in the deploy
configuration's <start managing_system="yes"> attribute.

The new API at gems/include/dialog/ aids the creation of simple GUI
applications based on the menu-view widget renderer. Its use is
illustrated by the simple test application at src/test/dialog/
that is accompanied with the dialog.run script.

This commits introduces changes to test number 4, so it must keep
more than one PKG. Also, it introduces a 5th test to verify that the
<remove_all/> functionality does delete everything in the depot.

This commits introduces improvements to the test functions to avoid
code duplication, and renames these functions to reflect better what they
are used for.

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.

This patch enhances Sculpt with the ability to detect user inactivity
for driving a screensaver by combining nitpicker's hover and focus
reports with a timer.
Issue #4950
* Removes all previous structs that represented an on-disc block layout
and were therfore subject to a number of layout restrictions (packed,
padding members, enum representations, etc.).
* Adds a replacement struct without any layout restrictions for each of the
removed structs. The new structs are named similar to the old structs.
* Adds block encoding and decoding utilities for easily converting from the
new structs to on-disc blocks and vice-versa (Block_scanner, Block_generator,
T::decode_to_blk, T::encode_from_blk)
* Adapts all affected places in the library to encode and decode proberly
instead of simply casting pointers.
* Thereby cleans up the hashing utilities to use typed-reference args instead
of void pointers.
* Re-enables run/tresor_tester and test-file_vault_vonfig_report for platforms
rpi, imx53_qsb, imx53_qsb_tz, imx6q_sabrelite, imx7d_sabre.

The depot_remove component can delete PKG archives with
automatically resolving dependencies and deleting archives that are not
required on the system anymore.
Issue genodelabs#4866
* Use jitterentropy only if supported.
On certain targets like pbxa9 or zynq_qemu, the performance counter always
yields 0, which renders jitterentropy unusable. On these platforms, the
Tresor tests now use a static value as entropy source instead.
* Adds a new package test-file_vault_config_report_no_entropy that is used by
the Depot Autopilot on targets without jitterentropy support instead of
test-file_vault_config_report. The only difference between the two packages
is the value of the above described new config attribute of the File Vault.
* Circumvent alignment fault.
The Tresor lib for now has the deficiency of using on-disc data structures
directly in code instead of decoding them first to unpacked, naturally
aligned structures. This causes problems with memory-access alignment on
several platforms (rpi, imx6q_sabrelite, imx53_qsb, imx7d_sabre). As fixing
this properly is a bit of work, the commit disables the tresor_tester and
file_vault_config_report test on the affected platforms in autopilot mode for
now.
* Further adjustments
* Make benchmarks optional
* Use a smaller tresor for rekeying
* Clean up image parameters
* No use implicit routes/resources
* Reduce ram consumption
* Reduce test timeout
* Raise cap quota, required for sel4 x86_64.
Ref #4819
* relaxes the timing and reduces the test steps because pistachio is quite
slow and would otherwise trigger problems with our easy approach of using a
dynamic rom instead of a proper manager
* provide IO_PORT and IRQ session to timer driver

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.
Issue #4861.
* ARM support and detaching from Ada/SPARK
* Remove all CBE-related code - especially the Ada/SPARK-based CBE library.
* We have no means or motivation of further maintaining big projects in
Ada/SPARK (the core Genode team is native to C++).
* The Genode Ada/SPARK toolchain and runtime don't support ARM so far - an
important architecture for Genode. This would mean extra commitment in
Ada/SPARK.
* We realize that block encryption more and more becomes a fundamental
feature of Genode systems.
* Implement a new block encryption library named Tresor that is inspired by
the design and feature set of the former CBE library and that is entirely
C++ and part of the Genode gems repository.
* The Tresor block encryption is backwards-compatible with the on-disk
data layout of the former CBE block encryption.
* Except from the snapshot management and the "dump" tool, the Tresor
block encryption provides the same feature set as the former CBE block
encryption and accepts the same user requests at the level of the
Tresor library API.
* So far, the Tresor block encryption does not support the creation of
user-defined snapshots.
* In contrast to the former CBE, the Tresor ecosystem has
no "dump" tool beause with the CBE library it turned out to be rarely of
use.
* In contrast to the Block back-end of the CBE "init" tool, the Tresor
"init" tool uses a File System back-end.
* The former CBE VFS-plugin is replaced with a new Tresor VFS-Plugin.
* The Tresor-VFS plugin in general is similar to the former CBE VFS but
has a slightly different API when it comes to re-keying and re-sizing.
Each of these operations now is controlled via two files. The first
file is named <operation> and the user writes the start command to it.
The user must then read this file once in order to drive the operation.
The read returns the result of the operation, once it is finished.
The second file is named <operation>_progress and can be watched and
read for obtaining the progress of the operation as percentage.
* The file vault is adapted to use the new Tresor ecosystem
instead of the former CBE ecosystem and thereby also gains ARM support.
* The former CBE tester and CBE VFS-tests are replaced by equivalent
Tresor variants and are now run on ARM as well (testing with a persistent
storage back-end is supported only when running on Linux).
* So far, the new Tresor block encryption has no internal cache for meta
data blocks like the former CBE.
* Add config/report user interface
* Add a second option for the administration front end to the file vault
named "config and report". With this front end the File Vault communicates
with the user via XML strings. A ROM session is requested for user input
and a Report session for user output. The front end type must be set at
startup via the component config and is a static setting. The graphical
front end that was used up to now is named "menu view" and remains the
default.
* The File Vault can now reflect its internal state and user input ("config
and report" mode only) at the LOG session via two new static config
attributes "verbose_state" and "verbose_ui_config" (both defaulting to
"no").
* The Shutdown button in "menu view" mode is replaced with a Lock button. The
new button doesn't terminate the File Vault but merely lock the encrypted
container and return to a cleared passphrase input. The same transition is
also provided in "config and report" mode.
* The file_vault.run script is replaced with file_vault_menu_view.run and
file_vault_cfg_report.run that address the two front end modes. In contrast
to the former script, which is interactive, the latter script is suitable
for automatic testing.
* There is a new recipe/pkg/test-file_vault_cfg_report that essentially does
the same as file_vault_cfg_report.run but uses the File Vault package and
can be executed with the Depot Autopilot. The new test package is added to
the default test list of depot_autopilot.run
* The File Vault README is updated to the new version of the component and
has gained a chapter "functional description".
* Fixes a regression with the cbe_init_trust_anchor component that prevented
reacting to a failed unlock attempt in the File Vault.
* The new Tresor software Trust Anchor has an optional deterministic mode in
which it replaces the normally randomized symmetric keys with 0. This mode
comes in handy for debugging. However, it should never be activated in
productive systems. When activated, the user is warned extensively on the
LOG that this system mode is insecure.
Ref #4819
This patch replaces the former 'nic_drv' and 'nic_drv_dtb' functions
by a more general 'nic_driver_routes' function that can return one or
multiple platform-specific ROM routes for NIC-driver binaries and dtb
files. This allows for supplying customizations for the wifi driver
as well. E.g., on the PinePhone, this hook can be used to handle the
renaming of the 'wifi_drv' to 'a64_wifi_drv'.

The screenshot trigger displays a little red dot at the upper-left
corner of the screen. When touched or clicked-on, it generates an
artificial key-press-release sequence for the print key and disappears
for one second. In this time, a separate screenshot component can handle
the print key by capturing the screen without the red dot appearing in
the saved picture.
With the new 'presets:' tag, .sculpt files can now refer to deploy
configurations to be integrated in the presets/ subdirectory of the
config file system. Those files can thereby be used as preconfigured
system scenarios. Such a preconfigured scenario can be loaded at
runtime by copying the preset file to config/deploy.
