This commits updates the contrib sources to version 8.7.1.
This version requires more random entropy as it queries OpenSSL
about the current random state and will bail if it is not sufficient.
Doubling the content of the '<inline>' VFS plugin as used in static
configurations seems satisfactory.
Furthermore DNS resolving needs a configured '<pipe>' plugin to work
properly.
Fixes#5184.
When the "system" ROM state turns to "suspend",
the S3 state information of the sleep_states ROM are determined and
are used to invoke the privileged Pd::system_control call.
Issue #5180
This commit raise various quota to accommodate using a display
resolution of up to '3840x2160' in the static parts, e.g. the
leitzentrale, of Sculpt.
Issue #5174.
Since "sculpt: adjust nitpicker priority", the nitpicker GUI server no
longer runs at the highest priority, yet the runtime_view of the
leitzentrale UI continued to operate at the highest priority.
On slower machines, this results in a visible interference of the CPU-
heavy rendering of the runtime_view with the (now) lower-prioritized
nitpicker, in particular laggy pointer movements.
This commit subordinates the leitzentrale components below the priority
of nitpicker to prevent this interference.
It also simplifies the priority scheme at the static system init: The
timer has the highest priority whereas all other components use the
priority band -1.
Issue #5174
The nightly Qemu tests that don't use KVM require more time for completing the
unlock-and-access phase of the test. If the lock phase starts to early, the
file access is interrupted and the output isn't as expected.
Furthermore, on FOC, the cap quota was insufficient.
Ref #5148
This substantially slims down the test in order to reduce the number nightly
tests that fail due to timeouts. Now, the extended test steps (maximum trees
and benchmarks) are only run on Linux. The synchronous access, snapshot
management, rekeying, and resizing tests were removed.
Ref #5148
This patch equips the menu-view component with the ability to present
more than one dialog at a time. The dialogs must be declared in the
<config> node as follows.
<config>
...
<dialog name="settings"/>
</config
For each dialog, menu view requests a dedicated ROM session labeled after
the dialog name. The corresponding GUI session is also labeled as such.
Note that only one hover report is generated responding to all dialogs.
The hover report can be correlated with the hovered dialog by inspecting
the the 'name' attribute of the hover report's <dialog> sub node.
The former global config attributes 'xpos', 'ypos', 'width', 'height',
'opaque', and 'background' have become attributes of the <dialog> node.
Fixes#5170
GPU drivers always reside in the runtime subsystem now.
This patch eliminates the risk of requesting a GPU session at the
drivers subsystem, which never gets established.
Issue #5150
On some platforms like qemu/x86_64/sel4, accessing the file system is so
slow that it used to hit the timeout of this phase in the run script.
Ref #5148
The new 'manager' config allows for the passing of configuration data the
sculpt manager without the need to modify the config/leitzentrale subsystem.
Issue #5166
The move of block, USB, and input drivers from the drivers subsystem to
the runtime alleviates the need for routing those sessions between the
subsystems.
Issue #5150
This patch moves SoC-specific framebuffer and touchscreen drivers
(PinePhone) to the runtime subsystem. They are enabled for the
phone_manager.
Issue #5150
This commit moves the USB and USB HID driver from the drivers subsystem
into the runtime. The former special USB node of the graph corresponds
now to the USB host-controller driver (named "usb"). The management
options for USB storage devices are available inside this component
node now.
Issue #5150
By moving the event_filter and the numlock_remap_rom from the drivers
subsystem to the static system, the filtering can be applied to drivers
hosted in the runtime and drivers hosted in the drivers subsystem.
This is a preparatory step for moving the USB host and HID drivers to
the runtime.

* replace tresor_init-local configuration type with simpler and more conformant
configuration type in tresor/types.h that does also XML-parsing and
XML-generation of configurations
* raise min degree to 2 because a degree of 1 is not practical und would
require additional logic

tree levels
Ref #5077
Adds a new command attribute "uninitialized_data" to the Tresor Tester
configuration. If a <request op="read"> command has this attribute set to "yes"
it assumes the read blocks to be uninitialized and therefore contain only 0's.
Note, that a command that has "uninitialized_data" set to "yes" cannot have the
attribute "salt".
Ref #5077
* differentiates request types that where merged formerly per module;
e.g. instead of type Superblock_control::Request, there are now types
* Superblock_control::Read_vbas
* Superblock_control::Write_vbas
* Superblock_control::Rekey
* Superblock_control::Initialize
* ...
each holding only the state and functionality that is required for exactly
that request
* removes all classes of the Tresor module framework and adapts all
Tresor- and File-Vault- related libs, apps, and tests accordingly
* the former "channel" state is merged into the new request types, meaning, a
request manages no longer only the "call" to a functionality but
also the execution of that functionality; every request has a lifetime
equal to the "call" and an execute method to be driven forward
* state that is used by a request but has a longer lifetime (e.g. VFS file
handles in Tresor::Crypto) is managed by the top level
of the user and handed over via the execute arguments; however, the
synchronization of multiple requests on this state is done by the module
(e.g. Tresor::Crypto)
* requests are now driven explicitly as first argument of the (overloaded)
execute method of their module; the module can, however, stall a request
by returning false without doing anything (used for synchronization on
resources)
* introduces Request_helper, Generated_request and Generatable_request in the
Tresor namespace in order to avoid the redundancy of sub-request generation
and execution
* moves access to Client-Data pointers up to Tresor::Virtual_block_device in
order to simplify Tresor::Block_io and Tresor::Crypto
* removes Tresor::Client_data and introduces pure interface
Client_data_interface in order to remove Tresor::Client_data and
move management of Client Data to the top level of a Tresor user
* introduces pure interface Crypto_files_interface in order to move management
of Crypto files to the top level of a Tresor user
* moves management of Block-IO and Trust-Anchor files to the top level of a
Tresor user
* adapts all execute methods, so, that they return the progress state
instead of modifying a reference argument
* removes Tresor::Request_and Tresor:Request and instead implements
scheduling at the top level of the Tresor user
* the Tresor Tester uses a list as schedule that holds Command objects; this
list ensures, that commands are started in the order of configuration
the Command type is a merge of the state of all possible commands that can
be configured at the Tresor Tester; the actual Tresor requests (if any) are
then allocated on-demand only
* the Tresor VFS plugin does not use a dynamic data structure for scheduling;
the plugin has 5 members that each reflect a distinct type of operation:
* initialize operation
* deinitialize operation
* data operation
* extend operation
* rekey operation
consequently, of each type, there can be only one operation in-flight at a
time; at the user front-end each operation (except "initialize") can be
controlled through a dedicated VFS file; for each of these files, the VFS
expects only one handle to be open at a time and only one file operation
(read, write, sync) active at a time; once an operation gets started it is
finished without preemtion (except of the interleaving at rekey and
extend); when multiple operations are waiting to be started the plugin
follows a static priority scheme:
init op > deinit op > data op > extend op > rekey op
there are some operation-specific details
* the initialize operation is started only by the plugin itself on startup
and will be driven as side effect by subsequent user calls to file
operations
* the data file is the only contiguous file in the front end and the file
operations work as on usual data files
* the other 3 files are transactional files and the user is expected to
follow this scheme when operating on them
1) stat (to determine file size)
2) seek to offset 0
3) read entire file once (this will be queued until there is no operation
of this type pending anymore and return the last result:
"none" | "failed" | "succeeded"; used primarily for synchronization)
4) write operation parameters (this returns immediately and marks the
operation as "requested")
5) read entire file once (the same as above but this time in order to
determine the operation result)
* the rekey op and deinitialize op are requested by writing "true"
* the extend op is requested by writing "tree=[TREE], blocks=[BLOCKS]"
where TREE is either "vbd" or "ft" and BLOCKS is the number of physical
4K blocks by which the physical range of the tresor container expands
(the physical range always starts at block address 0 and is always
expanded upwards)
* replaces the former <trust-anchor op="initialize"> command at the Tresor
Tester with <initialize-trust-achor> as there are no other trust anchor
operations that can be requested through the Tester config anyway
* removes the "sync" attribute from all commands at the Tresor Tester except
from <request op="rekey">, <request "extend_ft">, <request op="extend_vbd">;
as the Tester controls scheduling now, requests are generally synchronous;
at the rekeying and extension commands, the "sync" attribute determines
wether subsequent commands are interleaved with the execution of these
commands (if possible)
* removes "debug" config attribute from Tresor VFS plugin and reworks "verbose"
attribute to generate more sensible output
* removes NONCOPYABLE macro and instead uses Genode::Noncopyable and in-place
Constructors deletion
* introduces types Attr and Execute_attr where a constructor or execute method
have many arguments in order to raise readability
* renames the "hashsum" file that is provided by the Tresor Trust-Anchor VFS
plugin to "hash" in order to become conformant with the wording in the Tresor
lib
* makes the VFS Tresor test an automated test by merging in the functionality
of vfs_tresor_init.run and removing the interactive front end; removes
vfs_tresor_init.run as it is not needed anymore; adds consideration for
autopilot file structure in the Test and adds it to autopilot.list
* removes all snapshot controls and the progress files for rekeying and
extending from the Tresor VFS plugin; both functionalities were tested
only rudimentary by the VFS Tresor test and are not supported with the only
real user, the File Vault
* use /* .. */ instead of // ..
* use (..) instead of { .. } in init lists
Ref #5148
The virtual block device module used to hand over the wrong VBA as
parameter "rekeying VBA" to the Free Tree when allocating PBAs for data
access during rekeying. In certain constellations, this caused the Free
Tree to alloc PBAs that were still in use. The Free Tree PBA selection
algorithm, however, is just fine. When fixing the call parameter, it works
as desired. This re-enables the async rekeying test.
Ref #5075
The script tests the use of an encrypted file system that is created and
provided via the File Vault.
Furthermore the script can be used for test-driving existing File-Vault
containers (created with potentially older File-Vault versions) under the
current File-Vault version. This is done via the "LX_FS_DIR_TEMPLATE"
env variable.
Ref #5062
The tresor_check tool became outdated back when the Tresor project was created
by re-writing its predecessor, the CBE, in C++. At this time, the check tool
was merely renamed but not updated. As there was also no autopilot test for the
tool, the tool remained outdated.
This commit rewrites the tool for the most recent Tresor version and adds an
autopilot test.
Ref #5062
* Make command pool a proper module
* The command pool used to be kind of a module but it was driven via custom
tresor-tester specific code. Now, it becomes a proper module that
is driven by the module framework instead.
* Move the code for creating and handling the module-execution progress flag
into Module_composition::execute_modules as the function is always used with
this code surrounding it.
* Reorganize files, remove deprecated files
* A new class Module_channel is introduced in the module framework and all
channel classes inherit from it. With that class in place, the formerly
module-specific implementations of the following methods are replaced by
new generic implementations in the Module framework:
* ready_to_submit_request
* submit_request
* _peek_completed_request
* _drop_completed_request
* _peek_generated_request
* _drop_generated_request
* generated_request_complete
* Module requests are now held for the duration of their lifetime at the
module they originate from and not, like before, at their target module. As
a result, modules can generate new requests inline (without having to wait
for the target module), making code much simpler to read, reducing the amount
of channel state, and allowing for non-copyable request types.
* Introduce a sub-state-machine for securing a superblock in the
superblock_control module in order to reduce redundancy.
* Some modules, like free_tree, were completely re-designed in order to make
them more readable.
* Replace all conditional exceptions by using the macros in
tresor/assertion.h .
* Move methods that are used in multiple modules but that were implemented
redundantly in each module to tresor/types.h.
* Remove verbosity node and all that was related to it from tresor tester
config as the targeted verbosity can be achieved with the
VERBOSE_MODULE_COMMUNICATION flag in tresor/verbosity.h .
* Extract the aspect of translating the byte-granular I/O-requests to
tresor-block requests from the tresor VFS-plugin and move it to a new module
called splitter.
* Rename the files and interface of the hashing back-end to not reflect the used
hashing algorithm/config anymore, while at the same time making the hashing
interface strict regarding the used types.
* Introduce the NONCOPYABLE macro that makes marking a class noncopyable short
and clear.
* Replace the former tresor/vfs_utilities.h/.cc with a new tresor/file.h
that contains the classes Read_write_file and Write_only_file. These classes
significantly simplify the modules crypto, block_io, and trust_anchor by
moving the details of file access to a sub-state machine.
* The former, rather trivial block allocator module is replaced by a normal
object of type Pba_allocator that must be provided by the client of the
Sb_initializer (reference in the Sb_initializer_request).
Ref #5062
tresor: read uninitialized vbas as all zeroes
Virtual addresses in a Tresor container that were not yet written by the user
should always return a data block that is all-zeroes. This was the concept
right from the beginning of the project. However, somehow this aspect either
never got implement or got lost along the way.
Some context for understanding the commit: The Tresor doesn't initialize the
payload data blocks of a container when creating a new container as this would
be rather expensive. Instead, it marks the leaf metadata nodes of the
virtual-block-device tree (those that reference the payload data blocks in
physical address space) with generation 0.
Now, this commit ensures that, whenever the virtual-block-device module reads
such a generation-0 leaf, instead of asking the block_io and crypto to deliver
data from disc, it directly provides the user with 4K of zeroes.
Ref #5062
The order of execution inside the Tresor lib slightly changed compared to the
previous CBE lib. AFAICT, this is nothing to worry about and related to the
now cleaner structuring. However, it can produce higher peak requirements
regarding the allocation pool in the Free Tree. Therefor, this commit extends
the dimensions of the Free Tree used in the test.
Ref #4971
* Implement requests "create snapshot" and "discard snapshot" in tresor lib.
* Adapt tresor tester in order to test the new feature.
* Remove temporary code from tresor tester that skipped such requests with
the hint that they were not supported yet.
* Add mandatory "id" attribute to <request op="create_snapshot"/> and
<request op="discard_snapshot"/> tag. A "discard snapshot" command always
refers to the snapshot created by the "create snapshot" command with the
same "id" value.
* Clean-up command pool a bit.
Fix#4971
- always assign apps/overlay to targets (visible=true/false) to
prevent 0x0 geometry, which is interpreted as close
- add QMenu as exampel to panel button
- use usb-tablet on Qemu
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.

This data structure uses an AVL tree to maintain a time-sorted set of
alarm objects. It supports the use of circular clocks of an bit width.
Issue #5138
- 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.
