The box layout evenly distributes the child widgets according to the
number of children. This is not desired in the special case where a
child widget has a size of zero. The patch changes the layout algorithm
such that zero-sized widgets are not taken into account for distributing
residual space.
This patch replaces the former implicit "phonyness" of the rule by an
explicit .PHONY and installs a symlink from the target's build directory
to bin/ as is the usual practice for regular targets.

The parent-provides model is destroyed if no <parent-provides> node is
found in the configuration, which resulted in
Warning: list model not empty at destruction time
and leaking memory for the allocated nodes. The commit now explicitly
empties the list model in the destructor of ~Parent_provides_model.
Note, the case is implicitly tested in pkg/test-init by step "denial of
forwarded session request" and <init_config version="empty">.
Thanks to Peter for reporting this issue.

Whenever a domain looses all its interfaces or the link state of all attached
interfaces is down at once, the domain potentially moves to another Ethernet
segment and should therefore consider its ARP cache to be outdated.
RFC 826 states that "... If a host moves, any connections initiated by that
host will work, assuming its own address resolution table is cleared when it
moves. ...".
Therefore, this commit introduces clearing the ARP cache and the initially
stated events.
This commit was motivated by an issue with the PinePhone Modem and USB NIC.
On the PinePhone, the Modem has its own OS and acts as direct gateway to the
outer world for the USB NIC that is driven by Genode. However, whenever the
Modem gets restarted, Modem and USB NIC receive a new MAC address. This used
to conflict with the NIC routers ARP entry for the Modem that didn't cease to
be valid.
With this commit, the integrator of such a scenario at least has a convenient
way of fixing this by ensuring that all interfaces at the USB NIC domain go
down when resetting (e.g. by ensuring that the USB NIC is the only interface at
that domain).

When creating a socket, fd flags can be specified by ORing them with the
socket type. Most importantly, the flag SOCK_NONBLOCK must be propagated
to the Socket_fs::Context in order to support non-blocking recv/send.

The 'iput()' function is called from '__sock_release()' when the sock
object has no valid file object. The release function on the other hand
is called when the supplicant closes a socket.

Replaces the former use of the 'find_by_name' method of the AVL string tree.
This method returned a reference to the found object and threw an exception if
no matching object was found.
The locally implemented replacement doesn't return anything and doesn't throw
exceptions. It takes two lambda arguments instead. One for handling the case
that a match was found with a reference to the matching object as argument and
another for handling the case that no object matches.
This way, expensive exception handling can be avoided and object references
stay in a local scope.
Furthermore, this commit modifies the local wrapper for the insert method of
the AVL string tree, so, that it follows the above mentioned concept as well.

Furthermore, the commit introduces a convenience wrapper for finding the best
matching pair of transport rule and corresponding permit rule for a given
destination IP and port. This method as well follows the above mentioned

The 'with_libc' call at this point is not necessary and could be
harmful as it forces the usage of the user stack for the driver.
All code depending on this distinction should only be executed
from within the pthread.
Issue #4537.
Querying the RFKILL state led to execution of the Lx_kit::scheduler by
the pthread running the wpa_supplicant. As this may not happen the
RFKILL state is now solely managed by the driver and only the cached
state is read by the supplicant.
Fixes#4537.
Just add riscv spec files. The riscv versions should use MMIO transport
as ARM versions do. They also should work fine for riscv_qemu machine
from genode-riscv repository.
To not integrate referenced depot packages when building a sculpt image,
just set the environment variable DEPOT= to be empty. This allows to produce
slim images to the price that you have to publish the packages yourself.
In that case the sculpt run-script reminds you, and prints the package
versions.

On connector unplug the overall resolution of all available active connectors

connection with smaller resolution size. Additionally, update the documentation.
Issue #4531
acpica and the Intel display driver tries to use the Intel Opregion
simultaneously on Genode, which is not supported nor wanted for IO_MEM region as
which it is handled.
Attempts to remove the access to the region was not successful, since some
SSDT table contains ACPI AML code which is executed regularly and read/write
the Opregion.
The patch adds support to read in a copy of the Intel Opregion done by the
acpi_drv component. The copy was sufficient to make the Intel display driver
working to find and lookup the Intel VBT (video bios table) information to
setup all connectors on a Fujitsu U7411 docking station.
