This prevents diagnostic messages like
Error: partial write detected 0 vs 31
for writes into already released socket directories due to a still-open
handle to the socket data file.
We need to update the blueprint pkg path as well in case the start node
is changed. Otherwise the query tool will keep using the initially
configured pkg path.
In case the signature file is corrupt, e.g. it could not be downloaded
successfully, the gnupg code just prints an error message but will not
return the error to the user. So we patch the code to return the error
and check the value in the calling code.
The sinfo API now also exports PCI devices without logical IRQs.
Therefore, explicitly check interrupt count in get_msi_params() function
and ignore such devices.
- Use latest Muen version
- Sync VirtualBox Muen subject state
- Drop unneccessary subject IP patch
- Adapt Muen RUN_OPTs
- Update documentation
Note: the GPL 2017 toolchain is now required and as the debug output
format has changed the mulog-subject.py script must be updated on
autopilot instances.
Remove the dependency on the deprecated LwIP libary.
Remove the progress logging callback. Should a progress indicator be
desired, a progress report would be more appropriate.
Fix#2684
This patch improves the error handling for the case where the depot
lacks the content of the to-be-deployed pkg. Instead of infinitely
reattempting to obtain blueprints for such content, the deploy tool
prints a single message.
This patch adds two key remappings for the magic keys of the sculpt
scenario. KEY_DASHBOARD toggles the leitzentrale. KEY_RESTART resets
the noux-control subsystem of the leitzentrale.
Issue #2676
If only a single AHCI device is present, the block service provided by
the drivers subsystem allows the client to refer to this block device
via the label 'default'.
Issue #2676
This patch adds a safety check to nit_fb to ensures that nit_fb never
runs out of RAM. Should the available RAM not suffice for resizing the
virtual framebuffer to a new mode, it keeps the current mode.
The Dir_file_system uses static cast to convert handles from the
application to a plugin local type. For this reason, only the local
handle type may be returned from 'opendir' or 'open'. This fixes the
unexpected behavior when opening directories as files.
Fix#2533
This patch removes the notion of partial writes from the file-system
servers. Since write operations are asynchronously submitted, they are
expected to succeed completely, except for I/O errors. I/O errors are
propagated with the write acknowledgement but those are usually handled
out of band at the client side. Partial writes must never occur because
they would go undetected by clients, which usually don't wait for the
completion of each single write operation.
Until now, most file-system servers returned the number of written bytes
in the acknowledgement packet. If a server managed to write a part of
the request only, it issued the acknowledgement immediately where it
should have cared about writing the remaining part first.
The patch detects such misbehaving server-side code. If partial writes
unexpectedly occur, it prints a message and leaves the corresponding
request unacknowdleged.
Issue #2672
File_system clients may now watch files and directories for changes by
opening a 'Watch_handle' rather than submitting a 'CONTENT_CHANGED'
packet to the server. When a change happens at a node with an open
Watch_handle a CONTENT_CHANGED packet will be sent from the server to
the client. This serializes registration with other handle operations
and separates I/O handle state from notification handle state.
Test at run/fs_rom_update.

Catch out of RAM and capability exceptions and return error values.
Abort opening a composite directory at Dir_file_system where an
opendir call on any child file-system returns an OUT_OF_RAM or
OUT_OF_CAPS error.
Ref #2642
This change enables the use of negative values for the 'initial_width'
and 'initial_height' attributes to specify values that are relative to
the screen size. This is consistent with the meaning of the 'width' and
'height' attributes.
This patch changes the 'depot_deploy' tool to spawn any number of
runtimes. In contrast to the original version, which merely consumed a
blueprint generated by a pre-configured 'depot_query' instance, the new
version actively generates queries as needed. So there is a feedback
loop between 'depot_deploy' and 'depot_query'. The instantiation of
subsystems is controlled by the '<start>' nodes of the 'depot_deploy'
configuration. For each start node, the tool tries to determine the
ingredients (provided by the depot) by asking the 'depot_query' tool.
Once the information is complete, a corresponding start node of the
dynamic init instance is generated.
This patch introduces the subnodes <provides>, <requires>, and
<content> to the <runtime> node. All <rom> sessions that are
expected from the depot appear within the <content> node, which
sets them nicely apart from <rom> sessions that may be required
as runtime arguments.
Note that the <requires> and <provides> nodes do not appear in the
patch because the existing depot_deploy tool does not interpret this
information (the pkg/test-fs_report runtime does not provide any
service, and the timer session is provided as a common route).
This patch adds the config attribute 'query'. If set to the value "rom",
the query information is obtained from a ROM session labeled "query".
Otherwise, the query information is expected to be part of the config.
This enables us to use the component in two different scenarios. In
one scenario, 'depot_query' is embedded in a managed dynamic init.
Here, taking the query from the config is easy. In the other scenario,
'depot_query' is running as a daemon with a once-configured VFS but
varying queries. The queries originate from a component that does not
control the 'depot_query' config.
The new 'Terminal_session::size_changed_sigh' RPC function registers a
signal handler that is triggered each time when the terminal size
changes. It enables the client to adjust itself to the new size by
subsequently calling the 'size' RPC function. Of all terminal servers,
only the graphical terminal triggers this signal.
- handle line wraps in 'ech()'
- take (1,1) origin into account in 'hpa()' and 'vpa()'
- unify handling of SGR escape sequences of different lengths
- accept the '[?2004h' and '[?2004l' escape sequences (used by midnight commander)
Fixes#2671
The 'Expanding_reporter' wrapper for the 'Reporter' eliminates
the burden of handling 'Xml_generator::Buffer_exceeded' exceptions
from components that generate reports.
Fixes#2655
Instead of having a lot of platform specific quirks in the run test,
and to also test it on platforms currently missing a NIC driver,
this commit removes hardware drivers from the nic_router and
nic_bridge run scripts, and uses the nic_loopback server instead.
AVL trees can't be copied with the default copy constructor as the
parent pointer of the first item of both of the resulting trees would
point to the original tree. Copying an AVL node, however, generally
violates the integrity of the corresponding tree. The copy constructor
of Avl_tree is used in some places but in those places it can be
replaced easily. So, this commit deletes the copy constructor of
Avl_node_base which makes Avl_node and Avl_tree non-copyable.
Issue #2654
On platforms without nic or audio driver support, the corresponding
functions to return the correct names should return a meaningful
name instead of an empty list. Otherwise, in an erroneous run-script
that calls those functions to append names to the boot modules
the whole 'bin' directory is appended instead, which leads to big
image files or errors when linking the boot modules to core.
This patch adds hooks for customizing the location of the configure
script within the package, the build target, as well as the install
step. This is useful for packages like tcl that deviate from the
usual layout of source packages.
Issue #2648
The 'trace_logger' component can be used to easily gather, process and export
different types of tracing data. Which subjects to select is configurable via
session label policies and thread names. Which data to collect from the
selected subjects can be configured for each subject individually, for groups
of subjects, or for all subjects. The gathered data can be exported as log
output.
This is an example configuration of the 'trace_logger' component which shows
the default value for each attribute except the policy.thread and
policy.label:
! <config verbose="no"
! session_ram="10M"
! session_arg_buffer="4K"
! session_parent_levels="0"
! period_sec="5"
! activity="no"
! affinity="no"
! default_policy="null"
! default_buffer="4K">
!
! <policy label="init -> timer" />
! <policy label_suffix=" -> ram_fs" />
! <policy label_prefix="init -> encryption -> "
! thread="worker"
! buffer="4K"
! policy="null" />
! </config>

Fixes#2654
Building this policy was disabled by a REQUIRES = riscv_toolchain_bugfix
to prevent compiler crashes on nightly test builds. Since the latest
RISCV toolchain update, test builds for RISCV crash at much more places
which makes this single work-around senseless.
Issue #2654
Previously, base/trace/buffer.h included base/thread.h which includes
base/trace/logger.h which includes base/trace/buffer.h.
Removed the base/thread.h include in base/trace/buffer.h as it is not
needed.
Issue #2654
The 'Buffered_xml' utility is used by three components and a fourth is
on the way. To avoid another duplication of the code, this patch makes
it publicly available at 'os/buffered_xml.h'.
This patch replaces the 'Heap' by a 'Sliced_heap' to avoid the
allocation of a 16 KiB memory block when 'dummy' acts as a server. On
seL4, such an allocation would exceed the 1M quota as assigned by the
init.run script.
The 'initial_width' and 'initial_height' attributes were added to
accomodate the use-case to set the initial dimensions whenever 'nit_fb'
is used in a dynamic fashion, e.g, in combination with a window manager.
These attributes may not be mixed with the 'width' and 'height'
attributes, which are mostly used when a static size configuration is
desired.
When a NIC session is destructed at the router, we have to remove all ARP
cache entries that match the MAC address of that session. Otherwise the
outdated entries might be re-applied later, leading to wrong destination
MAC addresses in routed packets.
Fixes#2637
By specifying the 'config' of a '<runtime>' as an attribute, we can
distinguish the case where the config is obtained from a ROM session
from the case where the config is specified inline as a '<config>' node.
The new 'verify' component facilitates the code of GnuPG to verify
detached OpenPGP signatures against public keys.
Since GnuPG depends on libgcrypt and libgpg-error, the patch adds these
libraries to the libports repository.
Fixes#2640
This fix handles the case where the focused domain loses its focus
because the currently focused client vanishes. In this case, the focus
will be undefined and the non-focused views of the domain become
tinted again. The refresh should take effect immediately as soon as the
client vanishes.
