The main user of libsparkcrypto in the past was the CBE block encryption
ecosystem. However, the CBE was replaced with the Tresor block encryption that
uses libcrypto instead.
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
This split allows us to cross-compile all arm_v8a packages needed for
'goa build' by creating pkg/arm_v8a/goa.
The components featured on pkg/goa-linux are solely needed for 'goa
run'. As they contain a number of lx/hybrid components, pkg/goa-linux
must be complied on Linux running on the target architecture.
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.
Issue #4818
By managing downloads issued by the deploy subsystem via the
'Download_queue', failed downloads (e.g., due to HTTP error 404) are
properly tracked and don't cause infinite re-attempts.
Issue #4818
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'.
Related to issue #4813 and issue genodelabs/genode-allwinner#17.
This commit updates the used firmware images for the iwlwifi device
to latest available ones (supported by the current 6.1.x driver).
It also removes old firmware images that by now are not used anymore.
Fixes#4807.
Unfortunately, the change of "depot: remove empty config from
pkg/nano3d" broke the manual deployment of the nano3d demo because no
<config> is provided in this case.
This patch splits pkg/nano3d into two variants. The regular nano3d pkg
comes with an empty <config/> node as before. The unconfigured_nano3d
pkg does not feature any <config/> node and can thereby be configured
via a ROM route to a dynamic-rom service.
This patch equips the depot_download subsystem with the option to
explicitly skip the signature verification for downloads by specifying
the attribute 'verify="no"' for an <installation> item. This is useful
in scenarios where the lack of integrity of downloaded content does not
pose a risk, e.g., for untrusted applications that are rigidly
sandboxed, or during development.
Note that this option does not entirely discarge the signature checking.
Whenever an download has dependencies that are verifyable - for
which the public key exists in the depot - the dependencies are still
verified. This allows untrusted content to depend of verifyable content
while protecting the integrity the verifyable content.
Issue #4804
This patch adds the 'Verify' argument to all download-related interfaces
in order to control the checking of signatures for downloads. Note that
it does not change the sculpt_manager's existing built-in policy of
always checking signatures.
Issue #4804
This patch moves the interfaces needed for the interactive addition of runtime
components from the 'Popup_dialog' to the 'model/component.h'. So those
interfaces are no longer tied to one specific view implementation.
This free-standing function is meant to gradually replace
'Dialog::match_sub_dialog' interface, which relies on the caching of
the hover state. The new function is more flexible because dialogs do no
longer need to inherit 'Dialog'.
The missing else statements resulted in the addition of a
superfluous <archive> node when installing an <index>, causing
warning messages by the depot-download subsytem.
This patch adds the ability to specify an optional 'as' attribute in a
<rom> module declarion of a runtime file.
<runtime ...>
...
<content>
<rom label="camera-pinephone.dtb" as="dtb"/>
...
</content>
</runtime>
If specified, The depot-deploy tool uses the provided attribute value to
hand out the ROM 'camera-pinephone.dtb' under the label 'dtb' to the
subsystem.
Now, block_devices are reported earliest right after the devices ROM was
parsed and neither AHCI nor NVMe were found. If one or both devices were
found, the report is deferred after all expected reports arrived.
Issue #4791
The 'file_size' type denotes the size of files on disk in bytes. On
32-bit architectures it is larger than the size_t, which refers to
in-memory object sizes.
Whereas the use of 'file_size' is appropriate for ftruncate and seek, it
is not a suitable type for the parameters of read/write operations
because those operations refer to in-memory buffers.
This patch replaces the use of 'file_size' by size_t. However, since it
affects all sites where the read/write interface is uses, it takes the
opportunity to replace the C-style (pointer, size) arguments by
'Byte_range_ptr' and 'Const_byte_range_ptr'.
Issue #4706
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.
The touch-keyboard config accepts the new attributes 'opaque="yes"
and 'background=#112233' to control the dialog background. The
attributes are passed unmodified to embedded the menu view.
This patch add the support needed for implementing on-target
system-update functionality. The new 'empty' method is required for the
two-step procedure of updating image-index files - removing the old
index, followed by downloading the most current one. It is used to the
detect the completion of the first step.
Issue #4744
This patch reflects more details such as the percentage value for
downloads maintained in the download queue. This makes this information
easier to display at the GUI.
Issue #4744
This patch replaces the generic "In progress..." message by slightly
more concrete information about the type of operation. This is useful to
distinguish the two steps during the expansion of a partition.
This patch enhances the depot_download subsystem with support for
downloading and querying system images.
The installation ROM support the following two now download types:
<image_index path="<user>/image/index"/>
<image path="<user>/image/<name>"/>
Internally, the depot-download subsystem employs the depot-query
component to determine the missing depot content. This component
accepts the following two new queries:
<images user="..."/>
<image_index user="..."/>
If present in the query, depot_query generates reports labeled as
"images" and "image_index" respectively.
The also tracks the completion of each job depending on the depot-
query results, so that the final report contains a result for each
installation item requested. Prior this patch, the inactivity of the
depot-download manager (indicated by an empty state report) was
interpreted as success. But that prevents the proper association of
results and requested installation items.
Issue #4744
The 'scan' query for depot users used to list the names of depot users.
However, the URL and existence of a pubkey is useful to know when
assembling a GUI menu from this list.
Issue #4744
Each time when enlarging the menu view, a new 'Gui_buffer' is
constructed with the new size. At its contruction time, the default
reset background color is in effect, which is evaluated by
'reset_surface' as part of the construction. A custom reset color
takes effect only after the construction. Hence, when the Gui_buffer is
flushed to screen immediately at construction time, the gray default
becomes visible for a short time.
This patch changes the Gui_buffer to accept the reset background color
as construction argument so that it takes immediate effect.
