the superblock that was secured, it was renamed 'superblock_hash'.

By now, the symmetric keys were only XOR'ed with the private key as placeholder
for a real encryption. Now they are encrypted using AES256 with the TA's
private key as key
Ref #4032.
A private key of 256 bits is generated pseudo-randomly using the jitterentropy
VFS plugin on initialization. The private key is stored in the key file
encrypted via AES256 using the SHA256 hash of the users passphrase. When
unlocking the CBE device, the encrypted private key is read from the key file
and decrypted with the hash of the users passphrase.
Ref #4032
Instead of using the user passphrase directly, use its SHA256 hash calculated
using libcrypto. The passphrase hash is still stored in the key file to be
used as base for the very primitive way of generating the private key.

Closing the keyfile handle after a write operation wasn't synchronised to the
actual end of the write operation.
Issuing a write operation at the back end returns successfull as soon as the
back end has acknowledged that it will execute the operation. However, the
actual writing of the data might still be in progress at this point. But the
plugin used to close the file handle and declare the operation finished at this
point which led to warnings about acks on unknown file handles and leaking
resources. Now, the plugin issues a sync operation directly after the write
operation and waits for the sync to complete. This ensures that the plugin
doesn't declare the operation finished too early.
Ref #4032
The unlocking operation in the trust anchor was broken wich caused bad keys in
the CBE. This rewrites the whole operation to work as desired. Note that this
doesn't make it more safe! The private key is still almost the same as the
passphrase and stored plaintext.

The plugin used to close file handles via the 'vfs_env.root_dir.close'.
However, this lead to resource leaks and apparently isn't the right way to
do it. Other VFS plugins do it by calling 'close' directly on the handle and
doing it in the trust anchor plugin also, fixes the leaks.

There were no means for issuing a Deinitialize request at the CBE using the
CBE VFS plugin. The new control/deinitialize file fixes this. When writing
"true" to the file, a Deinitialize request is submitted at the CBE. When
reading the file, the state of the operation is returned as a string of the
format "[current_state] last-result: [last_result]" where [current_state] can
be "idle" or "in-progress" and [last_result] can be "none", "success", or
"failed".
Ref #4032
When discarding a snapshot, the CBE VFS plugin didn't communicate the ID of
the snapshot to the CBE. Instead it set the ID argument to 0. Therefore the
operation never had any effect.
Ref #4032
The snapshots file system used to return the number of snapshots on
'num_dirent' when called for the root directory although it was expected to
return 1. This confused the tooling ontop of the VFS.
Ref #4032
Despite being readable, the files control/extend and control/rekey proclaimed
that they were not when asked. This caused the fs_query tool to not report the
content of the files although it could have.
Ref #4032
Stat calls on the control/extend and control/rekey files returned a bogus file
size that led to an error in the VFS File_content tool. The tool complained
that the size of the file determined while reading the content differs from the
one reported by the stat operation. Now, the stat call will always determine
the actual size of what would be read. However, it isn't guaranteed that this
size doesn't change in the time after the stat operation and before the read
operation.

Both, trace_logger and vfs_trace had their own trace_buffer.h. This

WARNING: BREAKS CONFIG COMPATIBILITY!
This commit changes the configuration interface of the NIC router in a way that
may break systems that use the component without proper adjustment!
How to adjust:
At each occurrence of the 'dns_server_from' attribute in a NIC router
configuration replace the attribute name with 'dns_config_from'. The attribute
value remains unaltered.
DETAILED DESCRIPTION
The new attribute name 'dns_config_from' reflects that also other aspects of
the DNS configuration of the denominated domain are used by the DHCP server
that holds the attribute. This commit is a preparation for forwarding also the
domain name (DHCP option 15) with the mechanism behind the attribute.

Adapts Dir_file_system::open_composite_dirs in a way that it returns "success"
when the leaf node of the path is an empty directory but "lookup failed", as
usual, if one of the other directories on the way to the leaf node is empty.
I couldn't find a technical reason why we used to return "lookup failed" when
only the leaf node was empty.
The commit also adds a test for en empty root directory and empty
sub-directories to the fs_query run script.
Fixes#4198
The fs_query component used to exit with an uncaught exception if a queried
directory didn't exist. Now, fs_query will catch this event and simply skip the
affected query, thereby indicating to the user the inexistence of the
queried directory.

If no window has ever been focused, next() always returns an invalid
window id. As a consequence, there is no way to cycle through the focus
history without an explicit focus event (e.g. mouse hover).
Instead, next() should return the first window from the focus history if the
currently focused window is not present.

Adds the <new-file> operation to the fs_tool. When configured, the
<new-file path="...">...</new-file> tag will cause creation or overwriting of
the file given through the 'path' attribute. The file will contain the text
content of the tag.

This patch moves the utility from the app/text_area to os/vfs.h to make
it easier to use by other components. By hosting the 'New_file' as a
friend alongside the 'Directory', we can now pass a 'Directory' as
constructor argument, which is consistent with other utilities such as
'File_content'.
As a further improvement, the new version supports the implicit creation
of the directory hierarchy leading to the new file.

By adding an attribute 'size="yes"' to a query, one instructs fs_query to

The fs_query component used to try watching all files it found resulting in
errors on files that are not watchable. For some files, however, the watch-
feature doesn't make sense as they are not readable (no content, no size).
Now, fs_query will check first whether a file is readable and skip watching
if it isn't.

The default size is on most kernels 512M. On OKL4 we have to use 800M,

This patch fixes a GCC-10 compile error. Even though the optimization
was quite effective - I measured a speedup of factor 2 - it is not all

pthread.0 acquires a write buffer mutex and calls potentially
blocking fs operations. The EP thread handles session requests and tries to
acquire the same write buffer lock. IO progress events for pthread.0 are
handled by the EP thread, which however is blocking on the write buffer mutex.
The commit uses two write buffers, one which is filled by the EP and a second
which is used by pthread.0. The two buffers are swapped protected by a mutex
without invoking blocking fs operations.

Was still using the event_filter.config from drivers_interactive-pc
although a dedicated file is present in the raw archive.
The fix is just for consistency reasons, as sculpt manager is generating the
event_filter.config anyway.
This patch increases the RAM quota of the top-level nitpicker instance
to 12 MiB so that resize operations can be buffered for resolutions up
to 2560x1080. It mutes diagnostic messages of the form "Warning: Gui
(...) not enough RAM to preserve buffer content during resize" and
improves the window-resize experience.
With this patch, the user is able to re-gain access to the inspect view
by toggling the inspect button of a file system unrelated to the failed
USB storage device.
Fixes#4090
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

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.

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

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.

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.

The vfs pipe plugin can now be used as named pipe which anables data
