The USB host controller gets restarted during the suspend-resume cycle.
Hence, don't offer suspend while any USB storage device is in use, in
particular when deploying Sculpt from a USB stick.
Suspend/resume is not supposed to work with any framebuffer driver other
than intel_fb. Therefore, offer the suspend feature only when using intel_fb.
Issue #5174
The automatic restart of intel_fb got lost during the transition from
the driver manager. This commit restores the heartbeat monitoring of
this driver.
Issue #5174
This patch enhances the sculpt manager to drive the system state
and manage the lifecycle of driver components during suspend-
resume cycles.
The new Power options can be found in the System menu. The suspend
and power-off controls are presented only when the acpi-support
option is activated.
Note that the USB controller is hard restarted when resuming from
suspend. Hence, all components that depend on USB are restarted
implicitely.

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.

To differentiate between the legacy and the current VFS OSS plugin both

Issue #5167.
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 hard resource limit introduced by "sculpt: upper limit for automatic
quota upgrading" is too conservative for typical use cases of the RAM
fs. This commit makes the limit adjustable per managed component and
relaxes the limit for the RAM fs and depot_rom from 256 MiB to 2 GiB.
Issue #5174
Allow tweaking the driver selection using the manager config:
- The new attribute 'ps2="no"' suppresses the selection of the PS/2 driver.
- The new attribute 'intel_gpu="no"'suppresses the selection of the
Intel GPU and fb drivers, letting Sculpt fall back to VESA or boot-fb.
Note that the dynamic change of those attributes is handled in principle
but not advisable. E.g., disabling the intel driver after startup leaves
the hardware in a state that the VESA driver cannot cope with. However,
when statically defining the attributes in sculpt/manager/default, it is
now possible to build an image that uses VESA on an intel machine.
Issue #5174
The existing allocation scheme of window IDs has the unwelcome effect
that a re-appearing window would not always result in a visible change
of the window list. In such cases, the layouter and decorator would not
be prompted to do their job. This effect could be observered with the
multi-dialog version of menu view in Sculpt OS when manually enforcing
the restart of the runtime_view. Sometimes the panel would not re-appear
after the restart.
This patch changes the allocation of window ID such that new windows get
fresh IDs instead of reusing an ID of a recently disappeared window.
Issue #5170
This patch replaces the former use of one menu-view component per dialog
by a single menu view presenting all dialogs. This change reduces the
runtime config by about 20%, improves the boot time, and lowers RAM and
CPU usage at runtime.
Issue #5170
The font pointers cached in labels can become dangling when the style
database is updated, as happens when changing the font size dynamically.
This patch orderly updates the cached pointers before removing
out-of-date font entries from the style database.
Related to issue #5170
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
The new VFS OSS plugin utilizes the Record and Play session. For the
time being it is a drop-in replacement for the old plugin and shares
its limitations.
In contrast to the old plugin it is possible to force a client to
use a configured fragment size. Some clients work best with larger
fragments, e.g. VBox, where raising the minimal fragment size is
beneficial.
Please look at the README file for more information.
Issue genodelabs/genode#5167.
This patch lays the selection of the used storage target into the hands
of the config/manager file. By default, Sculpt selects the target by its
built-in heuristics, probing for a Sculpt partition. However, by
specifying a <target> node, one can explicitly select a storage target.
E.g., for using the 2nd partition of the SATA disk connected to port 1
of the AHCI controller, one can now specify:
<target driver="ahci" port="1" partition="2"/>
For selecting the ram_fs as target:
<target driver="ram_fs"/>
The latter case is particularly useful for custom Sculpt scenarios
deployed entirely from RAM. For such scenarios, add two lines to
your .sculpt file:
ram_fs: depot
manager: use_ram_fs
The first line configures the ram_fs such that the depot is mounted
as a tar archive. The second line configures the sculpt manager to
select the ram_fs as storage target. You can find this feature
exemplified in default-linux.sculpt scenario.
build/x86_64$ make run/sculpt_test KERNEL=linux BOARD=linux
It is worth noting that the configuration can be changed at runtime.
This allows for switching between different storage targets on the fly.
Issue #5166
This patch replaces the dynamic use of Attached_rom_dataspace by a
new Rom_handler utility, which implicitly covers the initial import of
content (safely using 'local_submit'), the registration of the signal
handler, passes the Xml_node to the handler function (no need to
manually call 'update'), and provides scoped access to the content via a
'with_xml' method. The latter reinforces a programming style that does
not need to copy Xml_node objects.
Issue #5150
This patch removes the remains of the original block-device discovery as
done by the former driver manager. Block sessions are now always
provided by components hosted in the runtime subsytem. The storage node
of the graph is no more.
Issue #5150
This patch harmonizes the driver management between the sculpt manager
and the phone manager by hosting the individual drivers in a new
'Drivers' class with a narrow interface towards 'Sculpt::Main'. The
patch also introduces a clean separation of the 'Board_info' between
features detected at runtime (on PC hardware), statically
known/managed features (phone hardware), and options that can be
toggled at runtime.
With common patterns for managing drivers in place now, this commit
also moves the former runtime/wifi_drv.cc and runtime/nic_drv.cc
code to driver/wifi.h and driver/nic.h. The _drv suffix of the wifi
and nic driver components have been dropped.
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
As the NVMe driver was the last remaining driver controlled by the
driver manager, this patch removes the 'drivers -> dynamic' subsystem
along with the driver manager from sculpt/drivers/pc.
Issue #5150
This patch moves the AHCI driver from the 'drivers -> dynamic'
subsystem to the runtime, managed by the sculpt_manager. One
implication of this change is the new need to supplement a device
port number to the 'Storage_target', in addition to the existing
label and partition. Previously, each block device was addressed by
merely a label specified for a parent session. The meanings of the
'Storage_target' elements are now as follows.
- The label corresponds to the driver component providing the storage.
- The port is used as block-session label when opening the session
at the driver.
- The partition(s) denote the partition information contained in
the block session.
Components operating as clients of the AHCI driver (e.g., a file system)
refer to their storage target as <label>-<port>.<partition> when a port
is defined (for AHCI). For drivers w/o ports, like USB storage where
each USB-block driver correponds to only one device, the storage target
is denoted as <label>.<partition>. When no partition table is present,
the '.<partition>' part is omitted.
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.

* fixes two places, where the free tree module used to continue to process a
request after actually having determined that the request fails
* moves the functionality of checking the hash of a read block and decoding it
to a dedicated method in order to improve readability
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
Snapshots must only be removed when securing the superblock. Otherwise, the
last secured superblock might get corrupted. The Free Tree allocation algorithm
would not consider the deleted snapshots anymore although they are still active
in the secured superblock and re-use their blocks. This would render the tresor
container unusable if the superblock with the deleted snapshots is not secured
in the end (driver crash, power down, ...).
Ref #5077
Superblock_control::Initialize used to decode a read superblock before checking
its hash. This is not necessary but may cause the operation to end up in a
decoding error on a superblock that is not the desired one anyway.
Ref #5077
Instead of iterating over all superblocks and checking each valid one,
check only the one whose hash matches the hash stored in the trust anchor.
I.e., the last one that was secured to the trust anchor. We must assume that
the other superblocks were corrupted in the meantime by operating the Tresor
container and, anyway, these Superblocks are not used anymore.
Ref #5077
The request of extending a tree used to halt when it found that
it could not add more levels to the tree because the maximum level index was
reached. Now, the library simply marks the request as failed, leaving it to
the user to handle the error condition.
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
During one of the many re-factorization steps that were applied to the Tresor
library and its predecessor, the CBE library, one of the main features of the
project, the integrity check, accidentally received a grave regression. The
most recent version of the Tresor still used to check all hashes of meta-data
blocks but ignored the hashes of the actual data blocks.
With this commit, the hashes of all but yet uninitialized data blocks get
checked. The reason for ignoring uninitialized blocks is that they are not
actually read from disc but simply generated as an all-zeros block in the
driver in order to prevent having to initialize them all to zero in
Tresor-Init. That said, the integrity of these blocks cannot be compomised.
The according hashes in the meta data remain unset until the data block gets
written for the first time.
Ref #5062
The request classes Block_io::Read_client_data and Block_io::Write_client_data
used to receive a block reference for no reason. This commit removes these
args.
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.

the hint that they were not supported yet.
* Add mandatory "id" attribute to <request op="create_snapshot"/> and

refers to the snapshot created by the "create snapshot" command with the
same "id" value.
* Clean-up command pool a bit.
Fix#4971
The re-keying state machine in the VBD module would use block data of the wrong
block for the hash update of an inner node in a certain circumstance.
On re-keying, the VBD iterates for a given VBA over all snapshots, beginning
with the newest and re-keys the VBA in each of the snapshots. At each snapshot
it therefore loads the branch of the VBA top-down, and then updates the branch
bottom-up. However, if loading a certain level of the branch of a certain
snapshot runs into the same physical block as with the last snapshot on this
level, the algorithm turns around and updates the branch from this point
upwards instead of going further down the whole way to the leaf. This is
because everything below this point has already been re-keyed in the course of
a newer snapshot.
The case where this turning around is not right above the leaf (i.e., the first
shared physical block is a metadata block) that's were the bug was located. In
this situation, we have to re-encode the highest shared metadata block into a
buffer again before starting to update. The update code acts as if the
mentioned block was just written back (which is true when going down all the
way to the leaf before updating) and consequently is present in the encoded
buffer.
Ref #4971
Until now, it was possible to use bad Free-Tree/VBD configurations with the
<initialize/> command. The tresor tester didn't complaining about it but the
tresor lib crashed or, worse, corrupted the tresor container. Now, the tresor
tester checks things, like for instance, that "nr_of_children" must be a power
of 2.
Ref #4971
The Superblock Control module now issues a snapshot garbage collection on each
incoming request. In return for that, the commit removes all calls to the
garbage collection from other modules.
Ref #4971
The Virtual Block Device module used to create a local copy of the Snapshots
array respectively Snapshot root it received with an incoming request. After
finishing the VBD operation on the copy, the source module of the request
used to back-copy the resulting Snapshot array resp. Snapshot root. This is
not only less efficient than referencing but also allowed a bug to sneak into
the new C++ implementation.
In contrast to the old Ada/SPARK implementation (CBE), the new design doesn't
allow for global objects that can be accessed by any module without receiving a
reference in a module request. Therefore, the Free Tree module has to receive a
reference to a Snapshots array with each request in order to be able to use it.
In our case, these requests are allocations for a "Write" operation from the
VBD. However, the VBD itself receives only the one Snapshot required for
writing and therefore causes the Free Tree to make bad decisions on whether or
not a block can be re-allocated or not.
With this commit, the VBD always receive a reference to the whole Snapshots
array and also propagates it this way to the Free Tree.

Replace the USB session API by one that provides a devices ROM only,
which contains information about all USB devices available for this client,
as well as methods to acquire and release a single device.
The acquisition of an USB device returns the capability to a device session

in between the client and the USB host controller driver. Moreover,
additional methods to acquire and release an USB interface can be used.
The acquisition of an USB interface returns the capability to an interface
session that includes a packet stream buffer to communicate either
bulk, interrupt, or isochronous transfers in between the client and the

This commit implements the API changes in behalf of the Genode C API's
USB server and client side. Addtionally, it provides Usb::Device,
Usb::Interface, and Usb::Endpoint utilities that can be used by native
C++ clients to use the new API and hide the sophisticated packet stream API.
The adaptations necessary target the following areas:
* lx_emul layer for USB host and client side
* Linux USB host controller driver port for PC
* Linux USB client ports: usb_hid_drv and usb_net_drv, additionally

trace monitor but the idea remained unimplemented. It is now superseded
by the use of the trace-session label as trace-subject filter.
Issue #847
The sculpt manager views only launchers in the + menu that are not present in
the runtime already. However, this check was missing when finding the right
launcher on a click event inside that menu. This could cause the manager to
try deploying an already deployed launcher a again (without any effect)
instead of deploying the launcher that was actually clicked.
Ref #5064
This patch mirrors the interface of Sculpt's distant_runtime to the
sandboxed_runtime variant, allowing the configuration of xpos, ypos,
min_width, min_height, opaque, and background color.
Issue #5008
This patch moves the text-editing facility of app/text_area to a
text-area widget as part of the dialog library. This has two benefits.
First, it simplifies app/text_area by using the dialog API. Second, the
editor can now easily be reused by other dialog-API-based applications.
Fixes#5058
The 'Dynamic_array' utility is used by the text_area as internal
representation of text. As a prerequisite step of making the text
editing features generally available as a text-area widget, the
utility must become public.
