The direct execution of application-level code by a watch handler is
troublesome because those handlers are executed at the I/O signal level.
In the concrete case, the watch handler got recursively called because
the handler called _handle_config (application-code), which called the
VFS, which in turn performed a wait_and_dispatch_one_io_signal, which
again invoked the watch handler.
The patch works around the problem by letting the watch notification
trigger the application-level signal for the _config_handler.
Fixes#4091
* The device XML information dataspace is only provided,
when the client's policy states `info="yes"`
* The device XM information gets changed to include the
physical resource names (I/O memory and IRQ addresses)
instead of virtual ids and page offset
Fix#4077
This API rework eases the access to memory-mapped I/O registers and
interrupts when using the platform driver. It introduces the notions of
- Platform::Device - one device obtained from a platform session
- Platform::Device::Mmio - locally-mapped MMIO registers of a device
- Platform::Device::Irq - interface for receiving device interrupts
The patch touches several drivers. Some drivers would require a
significant structural change to adopt the new API (e.g., net/virtio,
dde_linux drivers, imx gpio). In these cases, the patch adds
compatibility shims meant to be temporary. In other cases (e.g., imx
i2c), the adaptation was simple enough to carry through.
Fixes#4075
This patch adjusts the matching of the IP address such that the external
IP address is used as opposed the the NAT-local address. It is follow-up
fix of the conversion to the uplink session interface.

Apparently the skewed motion timings came from the issue fixed by
"timer: restore semantics of periodic timeout 0". With the current
version of the timer, the original motion parameters work just fine.
This patch restores the ability to launch nitpicker within a gui_fb
window. It is a follow-up fix for "nitpicker: make framebuffer and input
optional".
Issue #3812
This patch enables sculpt to utilize the CPU reset mechanism via the
PS/2 controller as well as the information provided via the ACPI FADT
information. Whenever the /config/system file is changed to <system
state="reset"/>, both mechanisms are triggered.
Supporting both mechanisms is useful because the PS/2-based reset does
not work reliably on modern machines. The PS/2-based reset is useful in
the case when the FADT reset information refers to the PS/2 command
port. In this case, the platform driver is unable to access this port
because it is already handed out to the PS/2 driver. In this case, the
PS/2 driver kicks in.
Issue #2726
This patch adds the handling neccessary for clients to upgrade the cap
quota of their GUI session. Until now, the upgrade mechanism supported
only RAM quota.
The limitation became visible once a client - in the particular case the
motif_decorator - attempted the cap upgrade of its GUI session. The cap
quota would arrive at the wm, but the wm would keep it instead of
forwarding the quota to nitpicker. This resulted in an infinite retry
loop at the motif_decorator, ultimatedly depleting all its cap quota.
The window manager infers the overall state from the intercepted input
events for the decorator and all GUI clients. However, each of those
parties have an independent input-event stream. Whereas the order of
events within one GUI session is strict, the order of events between GUI
sessions is arbitrary. The window manager wrongly relied on a global
event ordering to track the pointed-at GUI session.
The patch removes the assumption of a global event order by tracking the
relevant pointer state for each GUI session independently and evaluating
these states when propagating the pointer position to the decorator.
Fixes#4059
The addition of further keyboard layouts would otherwise pollute the
config/ directory too much.
Caution: When updating Sculpt OS, don't reuse your existing
config/event_filter file unmodified! You need to replace the chargen
includes, pointing to the new location, e.g.,
<include rom="en_us.chargen"/>
<include rom="special.chargen"/>
must be changed to
<include rom="keyboard/en_us"/>
<include rom="keyboard/special"/>
Issue #4055
This patch extends the settings dialog with the ability to select the
keyboard layout between the options that are included in the sculpt
image. The manual configuration is of course still possible by editing
the /config/event_filter directly.
If both the fonts configuration and the event-filter configuration are
managed manually, the settings button and window are not displayed.
Fixes#4055
By sorting the reported output, all consumers of the reports become able
to rely on a deterministic order. For example, the file browser of
Sculpt OS, the launcher menu items, and the depot-selection items will
appear in a predictable order.
Fixes#4054
This patch adds session-routing options to connect components to the
capture/event interfaces of the global nitpicker GUI server or the
leitzentrale GUI server. It thereby enables the implementation of screen
capturing components, remote management tools, or virtual keyboards.
Since those services are very powerful, they are subsumed under the
"hardware" category of the component graph as opposed to the GUI
category, which guarantees the separation of clients.
Fixes#4053
This patch adds 4 priority levels to the runtime subsystem. The highest
priority is used for components that are critical for the operation of
Sculpt, in particular the Leitzentrale GUI. All regularly deployed
components are assigned the lowest priority by default.
With priorities available in the runtime subsystem, this patch flattens
the priority levels at the top-level init to only two levels and
overlays the priority bands of the drivers, leitzentrale, and runtime
subsystems into one priority band. This has three benenfits:
- This change prevents the starvation of the Leitzentrale GUI from a
spinning high-priority driver (issue #3997).
- The change will also ease the hosting of latency-critical components
in the runtime subsystem that are prioritized higher than regular
components, the storage stack, and the network stack.
- The Leitzentrale GUI remains always perfectly responsive regardless
of the workloads deployed from packages. In the previous version,
the runtime graph was sometimes stuttering on high system load.
Issue #4045
This patch triggers the immediate removal of part_block once the
discovery of a fresh inserted USB stick has completed. Without the
patch, part_block was retained until the runtime was reconfigured the
next time for other reasons (e.g., toggling an inspect view). Until the
next reconfituration, part_block tended to stand in the way of directly
assigning the USB device to a VM.
This patch increases the RAM quota of the nitpicker instance for the
leitzentrale to make it suffice for the buffering of content during
resize operations. This fixes a flickering artifact when having an
inspect view open while entering a WLAN passphrase. When the connect
button appears or disappears (depending on the number of written
characters), some parts of the inspect terminal would flicker sometimes.
This prevents the log terminal from adjusting itself to the whole screen
size before the leitzentrale window layout is applied. This intermediate
size can otherwise exhaust the 8 MiB of RAM quota of the log terminal.
Issue #3970
This commit improves the performance of the pipe plugin by using local
signal handling and avoiding sending a signal during write when pipe
buffer is full.
Issue #3583
All pipe-ends were notified at the same time which leads to dead-locks.
This commit mitigates this by having a signal handler for each pipe and
each pipe-end respectively.

The vfs pipe plugin can now be used as named pipe which anables data
transfer via file handles from one component to another. E.g. if one

The deadlock reported in #3236 could be reproduced via the wm.run script
and the modification of test/nitpicker in commit "nitpicker: fix destroy

This patch fixes the deadlock by releasing the locked pointer early in
the destruction path, which is legitimate as the wm is single-threaded.

Let the NIC router provide an Uplink service besides the Nic service that it
already provided. Requests for an Uplink session towards the NIC router are
assigned to Domains using the same <policy> configuration tags that are used in
order to assign Nic session requests. The MAC addresses of Uplink session
components are _NOT_ considered during the allocation of MAC addresses for NIC
session components at the same Domain. The task of avoiding MAC address clashes
between Uplink session components and Nic session components is therefore left
to the integrator. Apart from that, Uplink session components are treated by
the NIC router like any other interface.

This patch complements the commit "nitpicker: defer hover changed while
dragging" with fixes of the window layouter and motif decorator.
- Handling of empty pointer model (after unhovering a decoration)
instead of not updating it.
- Re-applying the hover model to the window layout when leaving the
drag state. This addresses the corner case that the hover model
changed during the drag operation (which is rightfully not handled
while dragging).
- Letting the window layouter enter the drag state only if a dragged
window is defined.

Originally the outgoing buffer was flush when the terminal was
detached. Since we cannot do that at this point, make the flushing
part of the common cleanup procedure.
Issue #3682.
Rather than calling 'ssh_disconnect' from within the Terminal session,
flag the detached terminal in the session and let the event loop do the
cleanup. Otherwise it might happen that the 'ep' (handling the Terminal
session) as well as the 'pthread.0' (executing the ssh event loop) end
up both triggering the cleanup concurrently.

The CBE repository contained a lot of Genode-specific code despite the fact
that the CBE core logic is not bound to Genode in any way. Therefore the
Genode-specific CBE code is moved to the 'gems' repository to form part of
Genode mainline. The remaining CBE code becomes a port in Genode instead of
being invoked as sub-repository.
The commit combines the following work steps:
* add all files removed from CBE repository
* add CBE port files
* make all CBE libs and targets build again
* make all CBE run scripts succeed again
* make all CBE recipes build again

- Show "..." for resource-assignment menu entry because it leads
to a sub menu.
- Avoid dialog changes when clicking on "Add component" while a
routing or resource dialog is unfolded.
The initial implementation of the affinity configuration in
"depot_deploy: support affinity configuration" added the affinity
location attributes to the <start> node of the deploy config. This patch
moves the information into a dedicated <affinity> sub node as done by
the init configuration. So the context of the attributes 'xpos', 'ypos',
'width' and 'height' becomes clear.
It also fixes a usability issue in Sculpt that occurred during testing:
When configuring multiple components with custom affinities, the
resources dialog of later components would wrongly display the state of
earlier components instead of displaying the fresh (default) state. The
resulting configuration would then not match the displayed information.
This is fixed by resetting the dialog state.
As another minor cosmetic change, the patch adds a line break in front
of copied <config> or <heartbeat> nodes.
Issue #3597
With the move of the storage-management dialogs to the graph in Sculpt
version 20.02, the ability to unselect the buttons for destructive
storage operations such as format or expand disappeared. This patch

This patch allows the use of the VFS watch mechanism for the glyph file

Issue #3875
By default, Vim renames a written file to a backup file suffixed with
"~" before writing the current buffer to a new file. Consequently, there
exists an intermediate state when no file exists. Should a client watch
such a file to obtain dynamic configuration info, it observes the empty
state.
Some components have builtin heuristics for such a situation. In
particular, the window layouter falls back to a predefined default
'rules' if no rules are provided as a file. So when interactively
editing window-layouter rules using Vim, it can happen that the manually
maintained rules get overwritten by the default rules.
By setting 'set nowritebackup', we can sidestep this issue by preventing
Vim from producing the bad intermediate state.
Introduce the managing_system privilege for components like the

With this patch, sculpt uses init's heartbeat-monitoring mechanism to

The check prevents the Ttf_font from violating the bounding box in the
presence of very small scale values. This can happen during the startup
of Sculpt. Before the framebuffer driver is up, Sculpt bases its dynamic
font-size setting on a screen resolution of 1x1.
Issue #3812
The sculpt manager used to defer the initialization of the GUI until
nitpicker's first display report became ready. This way, Sculpt was able
to run headlessly even if the framebuffer driver failed to start up.
Thanks to #3827, nitpicker no longer depends on a working framebuffer
driver. So the sculpt manager is safe to rely on nitpicker in any case,
simplifying the code.

Ref #3848
This patch prevents nitpicker from requesting a framebuffer and input
session by default because the regular use of nitpicker relies on the
capture-session and event-session interfaces by now.
For supporting the nested use of nitpicker via the gui_fb component, it
is still possible to enable the traditional behavior by explicitely
setting the 'request_input' and 'request_framebuffer' config attributes
to "yes".
Issue #3812
This commit applies the transition from the "Input" session to the "Event"
session to the event-filtering mechansim. The functionality of the
input_filter is now provided by the event_filter. The event filter
requests only one "Event" session as destination for the filter result,
which is usually routed to the nitpicker GUI server. It provides an
"Event" service to which any number of event sources can connect.
The configuration of the filter chain remains almost the same. Only the
declaration of the <input> nodes is no longer needed. Instead, the
configuration must specify <policy> nodes, which define the mapping of
"Event" clients (event sources) to the inputs used in the filter chain.
The patch adjusts all uses of the nitpicker GUI server accordingly such
that the event filter reports events to nitpicker's event service
instead of having nitpicker request an "Input" session. This dissolves
the dependency of nitpicker from input drivers.
Issue #3827
This patch replaces the use of the "Framebuffer" session interface by
the new "Capture" session interface in all framebuffer drivers. Thanks
to this change, those drivers have become mere clients of the nitpicker
GUI server now, and are no longer critical for the liveliness of the GUI
server.
The patch touches the following areas:
- The actual driver components. The new versions of all drivers have
been tested on the respective hardware. Generally, the drivers
have become simpler.
- The drivers_interactive packages for various boards. The drivers
subsystem no longer provides a "Framebuffer" service but needs a
valid route to the "Capture" service provided by nitpicker.
- The driver manager of Sculpt OS.
- This patch changes the role of the test-framebuffer component from a
framebuffer client to a capture server so that drivers (capture clients)
can be directly connected to the test component without the nitpicker
server.
- Framebuffer driver no longer support the unbuffered mode.
- The fb_bench.run script is no longer very meaningful because it
interplays solely with nitpicker, not with the driver directly.
- All run scripts for graphical scenarios and the related depot
archives got adapted to the change.
Fixes#3813
Until now, Genode's framebuffer session interface was based on the
RGB565 pixel format. This patch changes the pixel format to 32-bit
XRGB where the X part is ignored. It adapts all graphical applications
and device drivers accordingly.
The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.
Fixes#3784
This commit fixes the 'Out_of_caps' handling. The previous version
mistakenly upgraded the RAM instead the caps as response. The problem

If a "cat" tool as simple as the removed one is needed, it should be

did not!
The 'WHITESPACE' case of the _calc_len method wrongly accessed the

This patch removes old 'Allocator_guard' utility and replaces its use
with the modern 'Constrained_ram_allocator'.
The adjustment of core in this respect has the side effect of a more
accurate capability accounting in core's CPU, TRACE, and RM services.
In particular, the dataspace capabilities needed for core-internal
allocations via the 'Sliced_heap' are accounted to the client now.
The same goes for nitpicker and nic_dump as other former users of the
allocator guard. Hence, the patch also touches code at the client and
server sides related to these services.
The only remaining user of the 'Allocator_guard' is the Intel GPU
driver. As the adaptation of this component would be too invasive
without testing, this patch leaves this component unchanged by keeping a
copy of the 'allocator_guard.h' locally at the component.

The value range supported by the 'Animated_rect' utility is constrained
to 2^11 by the used 32-bit integer type. The interpolation is performed
on fixpoint numbers with a fractional precision of 10 bits. The
non-linear interpolation as performed by the 'Lazy_value' utility
involves squaring the values. Hence, the interpolated integral values
must not exceed 2^11 (2*11 bits for the square plus 10 bit for the
fractional part require 32 bits). This range is too small for
high-resolution displays. Hence this patch replaces the 32-bit integer
type by a 64-bit integer type.
Fixes#3627
The wm used to remember the last pointer position when observing a leave
event. With such a stale pointer position, the wm would eventually
wrongly create an artifical motion event when a supposedly hovered
window changes its position (during an animated move). This can lead to
the propagation of the stale pointer position to the wm client, which,
in turn, may interpret the outdated position (e.g., the menu view would
report a wrong hover state).
This patch removes the stale state by resetting the '_pointer_pos' when
observing a leave event.

This patch is a follow-up fix for "ttf_font: prevent out-of-bounds
access", which produced sporadic single-pixel artifacts with large font
sizes, e.g., with the monospaced font set to 24px in Sculpt.
The artifacts occurred only for some horizontal sub-pixel positions, in
combination with the font cache, and after the rendering of '>'
characters. They were ultimately caused by the missed clearning of the
first pixel of a glyph where x0 is 1 (e.g., the character 'd'). In this
case, a pixel from the previously evicted cache entry (the '>') shined
through. The patch fixes the problem by clearing the glyph starting from
the first, not the x0's, pixel.

This test covers the situation where depot_query evaluates depot content

When copying config/managed/deploy to config/deploy, the latter may
temporarily result in an empty configuration. Such an intermediate
state should be ignored to keep the currently running scenario in tact
instead of restarting it.
Add a new plugin for creating pipes between pairs of VFS handles. It is
intended to replace the libc_pipe plugin, one of the last remaining libc
plugins.
In contrast to the libc_pipe plugin, this plugin defers cross-handle
notification until I/O signal handling rather than block and unblock
readers using a semaphore. This is a performance regression in the case
of multiple threads blocking on a pipe, but shall be an intermediate
mechanism pending renovations within the libc VFS and threading layers.
As a side effect, threads blocked on a pipe might not be resumed until
the main thread suspends and dispatches I/O signals.
The "test-libc_pipe" test has been adjusted to use the VFS pipe plugin

Fix#2303
Nowadays, we use standard command-line tools like vim to edit init
configurations dynamically, which alleviates the need for a custom CLI.
The CLI-monitor component was too limited for use cases like Sculpt
anyway.
The patch also removes the ancient (and untested for long time)
terminal_mux.run script, which used to be the only remaining user of the
CLI monitor.
Issue #3512
This patch extends the 'File_system::Status',
'File_system::Directory_entry', and the related 'Vfs' types with
the following additional information:
- Distinction between continuous and transactional files (Node_type)
(issue #3507)
- Readable, writeable, and executable attributes (Node_rwx),
replacing the former 'mode' bits
(issue #3030)
The types 'Node_rwx', 'Node_type' are defined twice,
once for the VFS (vfs/types.h) and once for the 'File_system'
session (file_system_session/file_system_session.h).
Similarly, there is a direct correspondance between
'Vfs::Directory_service::Dirent' and 'File_system::Directory_entry'.
This duplication of types follows the existing pattern of keeping the
VFS and file-system session independent from each other.
Moving the handling into the input-session clients enables more
sophisticated implementations (like Qt5) to apply key-symbol based
handling of those modifiers like correct CTRL-A with QWERTY and AZERTY
layouts and distinction of CTRL-J and Return.
Issue #3483
With the added modification-time support in the libc, the extract tool
requires a timer session, which is not plausible for the purpose of the
program.
This behavior stems from the fact that the libc implicitly writes the
mtime when closing a written file. For this update, it implicitly calls
'clock_gettime', which in turn initializes the timer subsystem within
the libc (creating a timer session).
For the extract tool, the implicitly updated mtime is useless because
the extract tool overwrites this modification time with the mtime stored
in the archive anyway. However, the dependency from a timer service
remains.
This patch explicitly disables the libc's implicit updating of the
file-modification when closing a written file.

This patch handles the situation where the usb_block_drv exits for any
reason, in particular when the driver fails to initialize the device. In
such cases, the usb_block_drv used to stay stale in the system,
effectively preventing the device from being passed to a VM. With the
patch, the USB storage device gets flagged as failed, the usb_block_drv
is removed from the runtime, and the condition is reflected at the user
interface.
This situation occurred on the attempt to access an iomega zip drive
with a version of the usb_block_drv without support for the START-STOP
command, but it may potentially also occur in other circumstances.
Fixes#3468
This commit implements the ssh exec channel request. It also handles
some shortcommings on the interactive channel like exit and concurrent

Pipes into the channel do not work yet. E.g.:
echo foobar | ssh noux@localhost -p 5555 "cat > /rw/test.txt"
The issue described with FIXME in Ssh::Server::incoming_connection()
could not be reproduced and might have been fixed with the improved
file descriptor handling.

Issue #3437
The triggering of a new depot query can happen more than once per
activation of the sculpt manager if multiple conditions call for updated
information about the depot. When this happens, the depot-query
component produces intermediate results, which are not consumed by the
sculpt manager. By deferring depot queries for a few milliseconds, we
avoid such intermediate queries, relieving the workload of the
depot-query component at system boot time.
Issue #3436
The diagnostic messages presented in the runtime dialog lacked the name
if the subsystem was created from a launcher, e.g., the 'vm'. Instead of
determining the subsystem name from the start-XML-node (a launcher has
no 'name' attribute but the name corresponds to the launcher's file
name), the name is now passed as a dedicated argument.
The labels of clipboard ROM and clipboard report sessions of WM clients
must be consistent with the client's nitpicker label. Hence, we must
route those sessions through the window manager, analogously to the
approach taken for shape reports in #3165.
Issue #3437
This patch introduces two caches to the depot-query tool.
- A stat cache remembers the results of 'Directory::file_exists'
calls.
- The 'Cached_rom_query' caches the result of scanning the depot
for a given ROM module and pkg path. To elminates the need to
parse 'archive' files of pkgs referenced from other pkgs or
for the repeated instantation of the same pkg.
Both caches are bypassed whenever referring to the 'local' depot user.
Fixes#3427
When resizing windows of clients that respond very slowly to resize
requests, the window's size sometimes snapped back to its original size
immediately after finishing the drag operation.
The problem was caused by the interplay of the layout rules (obtained
via the 'rules' ROM, generated by the 'rules' report) and the
temporary interactive state that occurs during drag operations.
The rules are updated only at the time of releasing the button to keep
the overhead while dragging the window low. However, when releasing the
mouse, the (now outdated) rules kicked back into effect, triggering
resize requests for the window to its old size.
The patch solves this problem by decoupling the dragged state of a
window from the physical release of the button. The button release
triggers a transition from a DRAGGING to a SETTLING state and programs
a timer. In the SETTLING state, the windows behave as in DRAGGING state,
giving the interactive geometry precedence over the rules-dictated
geometry. During this state, further responses of window-resize requests
may come in and are handled like dragging was still in progress. After a
timeout, however, the current window layout is conserved as a new rules
report and the state goes back to IDLE.
For clients that takes a very long time (in particular, VirtualBox when
resizing the desktop, which takes sometimes multiple seconds), the
snap-back artifact can still occur, but the effect is reduced.
This problem surfaced with the new tool chain that changes the stack
layout. A pointer to the the config XML data was kept in the main object
but pointed to a stack variable. This patch fixes it by removing the
pointer.
Fixes#3416
This patch adds the missing propagation of the maximized state from the
layout rules to the internal representation of a window. Without this
patch this state could be toggled by clicking on the maximizer button
only.
The decorator's detection of the hovered window element was inaccurate,
which resulted in "jumping" windows in some situations, ultimately
caused by a combination of three different mechanisms.
First, when moving the pointer into the area of a window, the decorator
would detect the hovering of the left border whenever the distance of
the pointer from the border was less than the half of the theme texture
(e.g., 64x64 pixels for the default theme). However, if the left border
margin is set to a small value (e.g., 1), there is an overlap of the
sensitive resize border area and the content. Hence, chances were quite
high that - when moving the pointer from the left into the window - the
hover report would contain the hovering of the left border.
Second, the window manager tries to hide pointer movements from the
decorator if possible. It informs the decorator of the pointer position
if any decoration is hovered or if a new window is hovered. But it does
not expose pointer movements within a window to the decorator. For this
reason, the decorator would not update the hover report as long as the
pointer stays within a once hovered window. In the situation described
above, the hover report would still contain the stale information about
the hovering of the left resize border.
Third, when the user clicks on the window, the decorator examines the
most recent hover report and - in the situation described above - finds
the left border hovered. Consequently, it initiates a window-drag
operation. While resizing the window with the left border, the window
layouter pins the right border of the window to its current position.
All window-size changes of the client will be applied towards the left
(dragged) border. In the case of the top view, which continuously
resizes the window by itself, the window would "jump". In reality, it
actually tries to respond an interactive resize operation. The window
layouter cannot guess that the client is not responding to window
layouter's resize request but is acting independently.
This patch fixes the jumping window problem for the case where the
pointer hovers the overlapping area of the resize border and the
content. However, when trying the to interactively resize the top window
via the bottom-left corner, the "jumping" can still be observed.
Fixes#3303
By decoupling the leitzentrale from the (contended) boot CPU, the fading

There are still nightly tests like test-tcp_bulk_lxip on sel4 x86_64 qemu
that manage to hit the test timeout of the run script although the test was
successful. So, raise the extra time added by the run script to 30 seconds.
Ref #3411
Some platforms (sel4 imx6/imx7) cannot manage to execute all tests in a single
boot. Thus, we re-boot them periodically after a given maximum number of tests
to avoid that arbitrary tests always fail due to the long uptime and not due to
the tests themselves.
If the maximum number of tests is set to 0, no limit is applied.

The terminal now got a configurable palette for 16 colors (8 normal, 8

Note, the old (undocumented) <color index="..." bg="..."> configuration
scheme is no longer supported.
Also, this commit adds a pleasing default palette that ensures
readability of ViM's standard hightlighting.
Fixes#3406
It might happen, in CPU intensive tests (like TCP bulk lxip), or when
printing debugging output after a failed test (as done currently on
staging), that the run script on the host gives up and reboots the
platform too early. Thus, we raise the buffer time. A reboot should
be necessary only in rare cases anyway.

This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.

As a preparatory step for introducing the new block-client API, we have
to turn the 'Block::Connection' into a class template. The template
argument will be used to tie an application-defined job type to the
block connection.
Issue #3283
This patch replaces the formerly fixed 2 KiB data alignment within the
packet-stream buffer by a server-defined alignment. This has two
benefits.
First, when using block servers that provide small block sizes like 512
bytes, we avoid fragmenting the packet-stream buffer, which occurs when
aligning 512-byte requests at 2 KiB boundaries. This reduces meta data
costs for the packet-stream allocator and also allows fitting more
requests into the buffer.
Second, block drivers with alignment constraints dictated by the
hardware can now pass those constraints to the client, thereby easing
the use of zero-copy DMA directly into the packet stream.
The alignment is determined by the Block::Session_client at construction
time and applied by the Block::Session_client::alloc_packet method.
Block-session clients should always use this method, not the 'alloc_packet'
method of the packet stream (tx source) directly. The latter merely
applies a default alignment of 2 KiB.
At the server side, the alignment is automatically checked by
block/component.h (old API) and block/request_stream.h (new API).
Issue #3274
This patch modernizes the 'Block::Session::info' interface. Instead of
using out parameters, the 'init' RPC function returns a compound 'Info'
object now. The rather complicated 'Operations' struct is replaced by
a 'writeable' attribute in the 'Info' object.
Fixes#3275
The 'aes_cbc_4k' library is simple wrapper around libsparkcrypto to
serve as a backend for storage encryption. It operates on data chunks of
4 KiB and uses AES-CBC while incorporating the block number and the
private key as salt values.
Replace the I/O response handler that is passed to the VFS at
construction with an object that is dynamically attached to handles.
This object shall also accept read-ready notifications, and plugins are
encouraged to keep handles awaiting ready-ready notifications separate
from handles that await I/O progress.
Replace the use of handle lists in plugins with handle queues, this
makes the code easier to understand and the ordering of notifications to
the application more explicit.
These changes replace the use of the Post_signal_hook from all VFS
plugins, applications must assume that read-ready and I/O notifications
occur during I/O signal dispatch and use an Io_progress_handler at its
entrypoints to defer response until after signal dispatching.
Fix#3257
The '_currently_constructed' pointer caches the information about which
'Launched_child' is currently configured in the menu. When discarding
the runtime (e.g., when un-using a file system) at this point, this
cached pointer was not invalidated while all 'Launched_child' objects
would be freed (including the currently constructed one). On the next
attempt to construct a new child, the sculpt manager attempted to
destruct the 'Launched_child' referred by the (now outdated)
'_currently_constructed' again.
Fixes#3240
This commit handles the corner case where a package could be installed
successfully but the package's runtime definition is inconsistent with
the content delivered by the package's dependencies, i.e., the <content>
of the runtime file lists ROM modules that do not exist.
With this patch, the '+' menu shows the message "installed but
incomplete" whenever a package is in such a state.
Issue #3241
The "Vfs::Vfs_handle" type should not contain any public members that
can be initialized by the VFS internally and by the application, so
remove inheritance from the "Genode::list::Element" class. The VFS
plugins must instead use lists of "Vfs::Vfs_handle" sub-classes, the
lifetime of which are always managed by the plugin.
Ref #3036
It turns out that the commit "window layouter: allow floating apps to
resize" interplays badly with the interactive toggling of the maximize
state of windows. In contrast to the window geometry and stacking, which
is always updated through the rules-feedback mechanism, interactive
changes of the maximize state omitted this loop and instead took a local
shortcut. Because of this shortcut, the maximized geometry eventually
ended up as window size in the window's assign rule. So unmaximizing the
window failed to revert the geometry to its original state.
This patch removes this inconsistency. The maximize state adheres to the
official chain of commands through the rules mechanism now. The state is
now maintained internally without affecting the window's geometry and is
evaluated while generating the window layout only.
As a minor loosely related improvement, this patch prevents the
highlighting of resize handles for non-resizable windows.
Issue #3200
This patch improves the transition from an interactive window geometry
change (dragging a window element) to the point where the resulting
new layout rules come into effect. During this short time, no resize
request must be issued because such a resize request would be based on
stale rules.
Fixes#3227
This is a follow-up commit to "Update <provides> info in pkg runtimes",
which adapts the users of the wm pkg to the changed label of the "focus"
nitpicker session.
This patch gives applications the ability to control the size of their
window whenever the window is floating, not tiled or maximized. See the
comment in the code for the rationale.
Fixes#3200
The default rate of 100 ms keeps Sculpt too busy because the menu that
displays the percentage values is drawn completely on each update.
Limiting the rate to 1/4 seconds relieves the effect.
By clicking on a yellow checkbox in the depot selection dialog, the
corresponding index files are removed. This way, index files can
be update by removing and downloading them again.
This patch also filters out sculpt-managed components from the graph to
avoid erratic graph-position changes while the '+' menu is open.
Fixes#3193

Issue #3193
This patch refines the criterion of when the networking is considered as
ready to use. Until now, any IP reported by the NIC router was taken as
an indicator for connectivity. But as the NIC router reports an IP
0.0.0.0/32 when no network cable is plugged at the uplink, the condition
was too loose.
This patch improves the error handling of depot-download manager for the
case where a download is requested but the corresponding software
provider information is absent from the depot. Without this patch, the
update mechanism would get stuck in the failed depot-query step and
won't attempt to perform subsequent download jobs.
Fixes#3224
The storage dialog is folded when activating the runtime view (e.g., by
clicking on the Genode Logo). This should happen immediately as response
of the mouse click.
This patch improves the separation of the update and layout phases to
avoid superfluous geometry animations of its child widgets. Prior this
patch, 'Widget::geometry' was called in both phases, potentially
triggering geometry animations with intermediate values at the update
phase.
Related to issue #3221
The button widget already supported an animated transition between
hovered and unhovered states. This patch generalizes the mechanism to
allow animated transitions between arbitrary button states, including
style changes.
This way, the fade-out of non-TCB components in Sculpt CE happens not
abruptly but smooth.
Fixes#3221
The default 'Rect' constructor constructs an invalid rectangle where the
p1 coordinates are lower than the p2 coordinates. In particular, p1 is
set to (1, 1). The 'Widget' implementation uses the points individually
as input into the 'Animated_rect' mechanism. This way, widgets end up
being positioned at (1, 1) initially and are moved to (0, 0) once the
first layout update is applied. By explicitly initializing the
'_geometry' to (0x0+0+0), we avoid this initial artifact.
When entering/leaving sub menus of Sculpt's '+' menu, some parts of the
menu sometimes remain unchanged, in particular the back button.
Originally, a click would reset the hovering on clicks in the
expectation that any click would eventually result in a completely new
situation where the old hovering information does not make sense and
would only (potentially) confuse the menu. But this was apparently
overzealous. With the patch a once hovered back button stays hovered
even when actitivated and the back button of the upper-level menu
happens to stay under the current pointer position.
Issue #3209
This patch improves the hover handling in situations where the dialog
changes under the pointer. Previously, hover changes were reported
as response to user input only, which failed to cover this case. This
became a problem with Sculpt CE's '+' menu, which changes on the fly
when entering/leaving sub menus.
The patch also cleanly separates the hover handling from the focus
handling. Originally, the hovering was reset when the menu view got
unfocused. In situations like Sculpt's '+' menu where the menu view
receives a transient focus only while clicked and gets unfocused on the
button-release event (aka clack), each clack would invalidate the hover
information until a new input event comes in.
Finally, the patch introduces the clear distinction between situations
where the entire dialog is hovered or not. Previously, this state was
somehow implicitly kept by issuing an invalid hover report whenever a
leave event was observed.
Issue #3209
When a window is moved, the virtual pointer position must be updated,
taking the changed input coordinate into account. This patch propagates
such changes via absolute motion events to the client.
Without this patch, Sculpt CE's '+' menu wouldn't update the hovered
item correctly when entering/leaving sub menus (which happen to trigger
the repositioning of the menu on screen).
Issue #3209
When specifying the attribute 'dep_visible="false"' for a primary
dependency or the attribute 'visible="false"' for a secondary
dependency, the dependency is used for the layout calculation but not
displayed in the graph.
- Omit showing routes to uninteresting ROMs obtained from the parent,
i.e., the binaries requested by the sculpt-managed subsystems.
- Change the routes for the inspect subsystem such that the inspect-noux
instance is anchored at the config node (critical!) and the nit_fb
instance anchored at the used GUI.
This patch excludes the current "Construction" from the list of
"present" components in the runtime. Without the patch, a missing "wm"
would go unmissing once when the routing dialog of a new wm instance
appears. Now an already present window layouter that had a broken route
would prematurely re-appear in the config, which should not happen
because the new wm does not exist yet.
When buiding the sculpt image, the sculpt.run script used to integrate
the current version of the index of the 'depot_user' into the boot
image. At runtime, when the Sculpt partition is selected for "use" this
index - along with the 'pubkey' and 'download' files of the known
depot users - is written to the Sculpt partition.
This has the undesirable effect that a later version of the index
(published some time after the sculpt image was created) would always be
overwritten by the outdated index shipped with the boot image.
The built-in default index was actually a stop-gap solution needed
during the development of Sculpt CE, introduced when the downloading of
index files was not yet supported. Now, with the working download
mechanism, it is no longer needed. Hence, this patch removes the default
index from the sculpt image.
This commit removes most of the default launchers, which are now
superseded by the interactive component addition feature of the '+'
menu.
We keep the chroot components because we cannot easily create chroot
instances interactively yet.
The usb_devices_rom is still needed because its configuration is meant
to be edited at runtime.
It also adds a 'themed_wm' launcher to make the initial sculpt
experience easier. For knowledgeable users, the index contains all
ingredients needed to build a multi-component window manager manually.
This commit turns the '+' menu into a tool for the following tasks:
- Selecting and downloading of depot index files
- Browsing of the hierarchical depot index files
- Installation of packages found in the index files
- Interactive routing configuration of a selected package
- Deployment of configured component
Sculpt used to restrict the size of leitzentrale windows to the screen
area that is not obstructed by the menu and log. This is useful for the
runtime view and the inspect window. However, the menu should be allowed
to use the entire screen because it overlays the other content.
Before this patch, the menu wouldn't be displayed completely on small
resolutions (e.g., 1024x768 when using the VESA driver) because the log
at the bottom of the screen imposed the size constraint on the menu.
With the patch, the menu is able to overlay the log window.
This patch enhances the runtime view such that not only immediate
dependencies but also all transitive dependencies of the selected
component are displayed. This way, the graph nicely reveals the
trusted computing base of the selection.
Instead of parsing the runtime's configuration each time when generating
the graph dialog (e.g., when changing the hover state), extract the
relevant information only on configuration changes.
The runtime view, launcher query, and depot query increase the
complexity of the graph without providing a tangible value to the user.
This patch omits those components from the runtime view to make the
graph less confusing.
Append "..." to button labels whenever the button does not perform an
immediate action but merely toggles user-interface elements. This
tells the user that the button can be pressed without risk.
With this commit, the 'installation' input of the depot-download
subsystem accepts <index> nodes in addition to <archive> nodes. Each
index node refers to one index file specified via the 'path' attribute.
This commit also improves the tracking of failure states. Once an
installation job failed (due to a download of verification error),
it won't get re-scheduled. In the past, such failure states were not kept
across subsequent import iterations, which could result in infinite
re-attempts when an installation contained archives from multiple users.
The the progress of the download process is now reflected by the
"progress" attribute on the download manager's state report, which
allows the final report to contain the list of installed/failed archives
along with the overall progress/completed state. The detection of the
latter is important for the sculpt manager for reattempting the
deployment of the completed packages.
The patch enhances the depot_download.run script to stress the new
abilities. In particular, the scenario downloads a mix of index files
(one present, one missing) and archives, from two different depot users
(genodelabs and nfeske).
Issue #3172
The input for the pkg index is located at gems/run/sculpt/index.
The sculpt.run script uses this input for generating the depot index
file at depot/<user>/index/<version>.
The tool/depot/publish tool support arguments of the form
<user>/index/<version> where <version> corresponds to the Sculpt
version.
Issue #3172
This prevents the situation where the user has booted the system, has
not yet selected a storage target to "use" for Sculpt, yet clicks on the
'+' menu. Such clicks show no immediate response because Sculpt cannot
know where to deploy the selected package. But since the user is not
guided towards resolving this prerequisite, it's better to not present
the menu in the first place. The '+' appears as soon as a storage target
is selected for "use".
This error message may occur during the startup of a multi-component
application when the very first dialog is generated just after the menu
view is ready. It is not an error.
This commit adds the following styles:
button/enter - for entering a sub menu
button/back - for returning from a sub menu
button/radio - for picking one item of a list
button/checkbox - for making a selection
frame/transient - for temporary GUI elements
This message is diagnostic, but also occurs in legitimate situations
such as the wm in Sculpt's Leitzentrale where the focus is managed
completely outside the wm.
The zynq nic_drv also depends on hw, we therefore adapted the folder
structure for clarity. Also renamed the binary to 'zynq_nic_drv' to
prevent conflicts and to allow removing the cadence_gem spec.
Issue #3179
This patch simplifies the propagation of pointer shapes from
window-manager clients to the pointer. The "shape" report is routed to
the wm server, which, in turn, reports it to the pointer. This way, the
pointer can easily correlate the label of the application's "shape"
report with the label of the application's Nitpicker session. The
formerly used manual rewriting of the "shape" label is not needed
anymore.
Since the wm server provides a "Report" service now, its <provides>
declaration must cover "Report" in addition to "Nitpicker" to avoid
runtime error messages. Vice versa, the wm is now expected to request
"shape" reports, which should be routed to the pointer (using the
'label_last' routing attribute).

The 'run_genode_until' procedure only called 'run_power_on' to reset
the target machine. That works will with the softreset module, which
is used by all x86-based test system but falls short regarding ARM
boards. The way those boards are connected requires turning the power
off and on for a complete cycle.
The situation where a 'Session_policy' is constructed for a label with
no matching policy is in almost all cases a configuration problem.
A diagnostic message eases pin-pointing such mistaks. By adding the
message to the 'Session_policy', servers don't need to manually handle
the exception to provide diagnostic information. This simplifies the
server code in many components.
In less interactive mode, the run script doesn't give up on missing test
archives but instead removes the corresponding tests and marks them "missing".
This mode avoids total failure of a platform in automated test infrastructures
when only a few archives are missing.
Fixes#3120
After a certain number of tests, presumably some resource in core is exceeded
and loading the successive test fails. This quickfix looks out for the
characteristic Core error and then reboots to avoid that all successive tests
are marked as failed.
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.
Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.
Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.
Issue #3101
This patch improves the appearance of the leitzentrale by eliminating
the (hardly visible) decorations from the GUI and graph views, and by
animating the motion of the graph position. The latter is meant to
remove the stuttering effect when the graph's size changes (and
re-centered).
This patch improves the consistency of the hover handling after
finishing a drag operation. Normally, the window manager hides pointer
updates while the user is performing a drag operation with the mouse
from the decorator. However, in the special case where a drag operation
results in a window-layout change, the decorator's hover model may be
affected. Hence, the window manager must supply the current pointer
position when leaving the drag state.

This commit adds the optional 'motion=<number>' attribute to the
decorator's <policy> nodes. The default value is 0. If a value higher
than 0 is specified, window-geometry changes are applied as an animation
where the <number> denotes the number of animation steps.
Issue #3096
This patch adds the boolean policy attribute "decoration", which
controls whether window decorations are presented or not. It is enabled
by default. By setting the attribute to "no", matching windows appear
without any border, which is desireable for Sculpt's component graph.
Issue #3096
This patch improves the window decorators in the following respects:
* Strict warnings are enabled now.
* The use of the 'List_model' makes the application of window-
layout changes more robust. This is particularly the case for
the restacking of windows.
* Display-mode changes are now supported by both decorators.
Issue #3094
Until now, decorators used to rely only on the TO_FRONT command for
propagating the window stacking to nitpicker. However, as the additional
use of the TO_BACK command allows for a more robust procedure, this
patch enhances the wm to handle both view stacking commands.
Issue #3094
Adds an config attribute to the Depot Autopilot component:
:<config repeat>:
Can be one of
"false" - process the given test list only once,
"until_forever" - endlessly repeat processing the given test list,
"until_failed" - repeat processing the given test list until it fails.
Adds an environment variable to the Depot Autopilot Run script:
:TEST_REPEAT:
Same as the <config repeat> attribute of the Depot Autopilot.
This is useful when having to debug very sporadic errors during one test
or a series of tests.
This ensures that the depot_autopilot.run script, when exiting, always prints
a result overview of the so far available test results, except the Depot
Autopilot component has managed to print the result overview up to this point.
Unequal numbers of double quotes let the XML parser of init fail,
therefore replace all double quotes when transfering previous
results after a reboot.
Ref #3027
The number of tests to run is the number of test package-archives minus the
the those that are skipped for the given platform. The number is printed
directly after checking if the given platform is supported by the run script.
It helps the surrounding test infrastructure to ensure that, for instance, a
result graph always reflects the same total number of tests, even though there
is a sporadic problem with booting the platform.
