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.
Issue #5009
This patch partially converts the Sculpt manager to the dialog API.
At this stage, both the old utilities and the new dialog API are still
used simultaneously.
Issue #5008
The so-called 'Distant_runtime' implements GUI dialogs via menu_view
components hosted at a distant init instance as opposed to child
components (as implemented by the 'Sandboxed_runtime'). This is
particular the case in Sculpt OS where the sculpt manager is not the
parent of the menu_view instances.
Issue #5008
By renaming 'Dialog' to 'Deprecated_dialog', we become able to use the
name 'Dialog' for the new API while temporarily keeping the original
interface in tact.
Issue #5008
- Increase default timeout to one minute
- Ignore power-button events during display-driver startup to avoid
entering another forced blank when pressing the power button twice.
- Prevent wakeup from user activity except for the power button.
So the volume can be adjusted without leaving the screensaver.
Issue #4950
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.
Issue #5008
Each hover change of the character position within a label results in a
new hover report, which needs to be evaluated by the application. For
the common cases where labels are used as button texts or for presenting
passive information, the level of detail is not needed while the
recurring hover reports induce overhead at the application side.
This patch mitigates this overhead by excluding labels from the hover
reporting by default.
For use cases that actually depend of precise hover reporting of labels,
for example an editable text area, the hover reporting can be enabled by
setting the 'hover="yes"' attribute of the label.
The 'Widget::_version' attribute was meant to allow the deliberate
replacement of a widget by a same-named widget by changing the version
while keeping the name, thereby suppressing any geomety animation.
However, the implementation missed to populate the attribute with the
value provided by the dialog ROM, prompting the unconditional
re-creation of the widget whenever a 'version' attribute was specified.
Even though this had the (desired) effect of preventing geometry
animations, it could cause feedback loops between hover reports and
dialog ROMs because the 'hover_changed' condition in 'Menu_view::Main'
would always stay true while a versioned widget is hovered.
This patch removes the obsolete 'io_progress_elem', which was wrongly
enqueued to the 'read_ready_waiters' fifo and not dequeued at
destruction time.
Fixes#4987
The Depot Autopilot used to filter out tabs and color sequences before
forwarding the test log to the own log. This commit prevents this and further
cleans up the string-filters code.
Ref #4922
The new 'log_prefix' attribute is effective when used in a tests runtime in
<succeed> or <fail> tags that have a non-empty content string. When matching
the log against the pattern given in the affected <succeed> or <fail> tag, the
Depot Autopilot will consider only those test-log lines that start with the
given prefix.
Ref #4922
* Removes the <event> tag from all test package runtime files and replaces the
contained <timeout> and <log> sub-tags with the new tags <succeed> and
<fail>. If a <succeed> or <fail> tag has a content, it defines a log pattern
that should be recognized and render the test failed or successful. If a
<succeed> or <fail> tag has an attribute after_seconds that is not set to 0,
it defines a timeout after which the test should be rendered failed or
successful.
* Adapts the Depot Autopilot to support the new syntax in the test-package
runtime files. However, for now, the Depot Autopilot is kept compatible to
the old syntax as well. If the <events> tag is present, it is prioritized
over the new syntax.
Fixes#4922
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 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
Fixes alignment faults that occured in the AES256 implementations while
wrapping or unwrapping keys on imx53_qsb, imx6q_sabrelite, and imx7d_sabre.
The problem was that the unwrap_key/wrap_key functions did reinterpret casts
from unsigned char pointers to uint64_t pointers and then directly used the 64
bit values of referenced by the latter. Most probably this caused the compiler
to optimize operations in the assumption that the pointer is 8-byte aligned
which then created alignment faults.
As a solution, this commit changes the interface of the wrap_key/unwrap_key
functions to take uint64 pointers as arguments instead of unsigned char
pointers and then adapts the function users to ensure that they refer to
appropriately aligned memory regions.
Fixed#4932
* 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.

In some instances, the fetchurl progress determined by
depot_download_manager will be empty when the download fails (e.g. due
to a 404), this commit fixes a bug where this would be interpreted as
the download having completed which would subsequently start hash
verification of a package that has never actually been downloaded.
Fixes#4919
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.

The debug mode turned out to be unnecessry because the plugin can be simply
replaced with an <inline> file VFS plugin that has a content size of 32 bytes.
Ref #4819
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 solves keyboard-focus issues with the wifi dialog that were
caused by making the focus update conditional. However, since the update
is not expensive, we can unconditionally re-evaluate the focus atfer
each user interaction.
Issue #4820Fixes#4856
This patch includes the system dialog in the global keyboard focus
handling, supports hovering of the "Edit" and "Add" buttons,
allows the use of the enter key to finish URL editing, and
triggers a re-scan of depot users after adding a new one.
Issue #4820
Should the selected depot user not be present in the depot - for example
after switching the sculpt partition to another - unfold the selection
of all present depot users so that the one can pick an existing one.
Issue #4820
We repeatedly experience issues with XHCI handoff in the USB host driver
at runtime on modern systems. Mostly, these issues manifest as
initialization delays with very high CPU load. Investigations show that
during this time the handoff MMIO write does not return, which hints the
firmware driver enters some spinning loop. I suspect the enabled IOMMU
does not play well with the firmware due to insufficient RMRR
information.
Therefore, we disable USB handoff in Sculpt via the driver manager (as
we do for dedicated devices already in other contexts). Note, UHCI and
EHCI handoff is still done in the platform driver and succeeds on all
our test hardware.
Issue #4820
Fixes a regression with the cbe_init_trust_anchor component that prevented
reacting to a failed unlock attempt in the File Vault. The regression was
caused by new semantics in the vfs that did not allow for using the file
operation result as indicator for whether the unlock attempt failed or
succeeded. The correct and hereby applied approach is to check for the data
read from the file after having written the unlock command. The data reads
either "ok" or "failed".
This patch mitigates potential busy feedback effects when evaluating the
reports produced by 'depot_deploy' in a closed control loop. Reports
are now generated only if the deployment state has changed.
Issue #4818
This patch marks a child as incomplete if one of the ROM modules listed
in its blueprint is missing. This, in turn, triggers the update system
in Sculpt, which then tries to download the missing pieces.
