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.

env variable.
Ref #5062
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

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.

* 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.

* 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,

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

* 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

* Native usb_block_drv
* black_hole component
* Port of libusb, including smartcard and usb_webcam driver depending on it
* Port of Qemu XHCI model library, including vbox5 & vbox6 depending on it

Commit "menu_view: ignore zero-sized widgets in box layout" introduces
zero-sized child widgets as a special case but defined zero-sized as
zero covered pixels (w*h == 0). However, for layouting, a widget with a
non-zero height and zero width is not zero-sized.
This patch refines the zero-size condition such that only widgets with
both zero width and zero height are considered as zero-sized.
It thereby solves the missing display of empty lines in the text_area
component.
This is a follow-up fix for commit "sculpt: apply Dialog API to diag,
panel, and graph", which happened to render the legacy dialogs (network
and settings) inaccessible.
The patch avoids the use of clack seq numbers for the 'popup_opened'
condition (which happens on click, not clack). It also overrides old
click information on the arrival of a new click, avoiding the evaluation
of stale click sequence numbers in distant_runtime.cc. Furthermore, it
reduces the rate of 'Distant_runtime::_try_handle_click_and_clack'.

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.

<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

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.

* 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.

* 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

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.

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.
