The service is loaded dynamically VBoxSharedClipboard.so at runtime. The
VFS configuration mounts the shared object at /VBoxSharedClipboard.so as
the file is checked by contrib code before loading. An init
configuration in pkg/vbox6/runtime illustrates this and how to re-label
the VBoxSharedClipboard.so ROM to its real name
virtualbox6-sharedclipboard.lib.so.
During Windows 10 boot with sequential block requests, the AHCI request
worker finished earlier than the EMT thread signals hEvtProcess and
begins waiting for hEvtProcessAck indefinitely. The timeouts helps to
survive this short phase.
A better solution would use conditional variables, which are not
provided in VirtualBox's runtime.
In ROM mode the global CapsLock state is controlled by the capslock ROM
by virtual KEY_CAPSLOCK events.
Guests are easily confused by spurious KEY_CAPSLOCK input events in
caps="rom" mode. These spurious events may reach the VMM if KEY_CAPSLOCK
is not pressed as first key in a combination and, therefore, is not
filtered as global key. We filter KEY_CAPSLOCK in ROM mode in the VMM
explicitly, but let it pass in non-ROM mode.
Per default RAW mode is used and CapsLock key events are sent unfiltered
to the guest.

Revert GNU ld to the old behavior where sections with the same name in multiple
ld scripts are merged. Binutils 2.36.1 creates two sections with the same name.

Download gmp, mpc and mpfr with the download script provided by the
gcc source tree and let the gcc build system handle the build of these
libraries with the correct compile options. This fixes build issues on
armhf Linux and removes the need to maintain mpc and mpfr ports in
the Genode tree.
Issue #4094
GDB monitor re-uses internal parts of the sandbox library. It thereby
relies on the internal detail of how local headers are included (using
"" instead of the now usual practice <>). A seemingly unrelated change
"init/sandbox: avoid repetitive state reports" eventually broke the
build of the GDB monitor.
This patch makes the GDB monitor less reliant on the way of how the
sandbox includes headers internally.
It also fixes a few warnings caused by the double definition of
__GENODE__ (adding an missing include guard and making the #define
conditional).

Note, OpenSSL now comes as one combined depot archive *openssl* that
replaces the former *libssl* and *libcrypto* archives. The libraries are
still separate binaries for compatibility with legacy software.
Issue #3773
The contrib code is updated from 2.4.1 to version 5.2.0 and the used
device-model is changed to QEMU xHCI. Due to this change older guests
OSes, namely Windows 7, that relied on the NEC xHCI device-model will
not work anymore.
The 'Qemu::Controller' interface was extended by an 'info' method, which
returns the vendor and product ID. This allows for removing the
hard-coded values in the VirtualBox glue code.
Issue #4018.
The former implemention assumed that the guest physical memory is
mapped continously. This, however, is not true. Writing larger
files to an USB stick with a Windows 10 guest would therefore lead
to data corruption.
The current implementation uses a bounce buffer to copy the data
to and from the guest physical memory and leaves dealing with the
memory mappings entirely up to the VMM.
Fixes#4017.
This commit restores the diag feature for selecting diagnostic output of
services provided by core. This feature became unavailable with commit
"base: remove dependency from deprecated APIs", which hard-wired the
diag flag for core services to false.
To control this feature, three possible policies can be expressed in a
routing target of init's configuration:
* Forcing silence by specifying 'diag="no"'
* Enabling diagnostics by specifying 'diag="yes"'
* Forwarding the preference of the client by omitting the 'diag'
attribute
Fixes#3962
By default, bash brings its own version of 'getenv', named exactly like
the libc function. This becomes a problem in fork/execve scenarios if
the dynamic linker resolves 'getenv' to the bash binary instead of the
libc.
This patch fixes the generate step of the genodians.org scenario.
Issue #3882
Introduce the managing_system privilege for components like the
platform_driver to allow it to call system management functionality
that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware.
The former RAM resource configuration attribute `constrain_phys`,
which enabled to constrain the region of physical RAM to be used,
gets replaced by the new, broader managing_system configuration
attribute of a `start` node. It gets enforced by the sandbox library.

The patches disable VBOX_IGNORE_FLUSH and a sanity check in the VMDK
backend. This enables passing an explicit flush request by the guest

Fixes#3743.
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
- Since Genode::strncpy is not 100% compatible with the POSIX
strncpy function, better use a distinct name.
- Remove bogus return value from the function, easing the potential
enforcement of mandatory return-value checks later.
Fixes#3752
This patch is a workaround for the missing implementation of
'Pd_session::transfer_quota' interface by the GDB monitor's PD service.
The missing implementation becomes problematic with the changes of #3750
that enabled the cap-quota accounting for core's CPU service.
In regular scenarios without the GDB monitor, the client of
'Cpu_session::create_thread' deals with Out_of_caps or Out_of_ram by
upgrading the CPU session's cap and RAM quotas. This, in turn, results
in a sequence of 'transfer_quota' operations at the parent.
Since GDB monitor implements a custom PD service, these 'transfer_quota'
calls try to transfer quota between sessions provided by core and those
provided by the GDB monitor. This does of course not work. To fix this
issue, the GDB monitor needs a major overhaul. This patch side-steps
the problem by handing Out_of_caps and Out_of_ram from the debuging
target.
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.
Fixes#3750
This patch prefixes a few symbols in the make binary that are offered by
both the libc and the make binary. The clash of symbol names produces
confusing runtime linkage otherwise. This becomes a problem during
fork/evecve.
This patch extracts the child-management functionality from the init
component into a new library called "sandbox". The library API is
located at 'os/include/os/sandbox.h'.
The sandbox API allows for the interaction of the component with the
sandboxed children by providing locally implemented services. This
mechanism is illustrated by the new test at os/src/test/sandbox.

- Any input resets update rate to 100Hz in graphic mode, which gets

Make sure timers run at the same priority as component threads, otherwise
no timer progress can be made. See 'rtTimeNanoTSInternalRef' (timesupref.h)
and 'rtTimerLRThread' (timerlr-generic.cpp).
This is a follow-up patch for "noux: don't update mtimes for read-only
files". It eliminates warning messages during Sculpt's prepare step when
'cp' tries to update the mtimes of the source files.
This is a follow-up patch for issue #1784 that solves two
inconsistencies.
- The Vfs::Timestamp::INVALID matches File_system::Timestamp::INVALID
- The Noux libc plugin tests for Timestamp::INVALID instead of a
positive value.
The patch fixes the mtime info as shown in directory listings in
Sculpt's inspect window.

Issue #3550
This is an intermediate fix to handle sends to sockets shut down by the
peer already. A final fix in the libc would add support for the
MSG_NOSIGNAL send flag, generate SIGPIPE, and return the expected EINTR.
Then this patch is no longer required.
This commit also drops the obsolete patch for missing
sysconf(_SC_NPROCESSORS_ONLN), which is now part of libc.
