a15c894385 file_system_session: increase TX_QUEUE_SIZE to 32
The change of the queue size from 16 to 32 has negligible costs (4 KiB
instead of 2 KiB for the packet-stream queues) while facilitating the
batching of many small consecutive write operations.

10aa5ebf03 pci_decode: report devices from ACPI info
Although we do not have the full ACPI information parsed yet, to
announce non-PCI devices derived from the ACPI tables, the device
description of the assumed devices is now integral-part of pci_decode.
Formerly, the information was gained separatedly as boot-module, whereby
we lost synchronization in between ACPI/PCI parsing, BIOS handover, and
PS/2 emulation code already acting.

4bacba431b nvme_drv: do not mask interrupts
During interrupt handling the driver masked and cleared interrupts as
recommended in the spec to prevent spurious or unnecessary interrupts
from occurring.

Due to the way the current implementation operates new Block requests
got submitted while handling completions for already finished ones.
Since interrupts where masked at this point the controller did not
generate interrupts when the newly submitted requests got completed.

As the mask/clear optimization is apparently not strictly needed and
according to the spec undefined when using MSI-X it is removed.

49b4b8597d os/pin_driver: support for time-multiplexed in/out
This patch equips the pin-driver framework with support for the
time-multiplexed operation of a pin as output or input. This is needed
when implementing I2C communication via a bit-banging driver.

To operate pin in both directions, a driver obtains both a pin-state and
a pin-control session for the same pin. The pin-state session can be
used to sense the current pin state. The control session allows the
client to set the pin to high or low (using the 'state' method), or to
set it to high-impedance via the 'yield' method. Once switched to
high-impedance, the pin can be used as input.

c83f307b62 nic_router: consider DHCP client optimization
Some DHCP clients (Debian VM in Sculpt) persistently store the last lease they
obtained and try to directly DHCP REQUEST it on a new startup whithout doing
DHCP DISCOVER beforehand. In case the NIC router doesn't know about the lease
anymore (timeout, new router instance), the router used to just ignore the DHCP
REQUEST. This led to significant delays in the network startup of the client
(delayed retries until give-up and DHCP DISCOVER). With this commit, the router
answers such packets with a DHCP NAK instead, causing the client to directly
switch to DHCP DISCOVER.

99254b4d52 nic_router: bind link state to remote DNS config
The NIC router README claims that the 'dns_config_from' attribute in a DHCP
server configuration binds the propagated link state of all interfaces at the
domain of the server to the validity of the IP config of the domain that is
given through 'dns_config_from'.

However, this was not true. The router missed to implement this detail which
led to clients of such a DHCP server sending DHCP DISCOVER packets too early.
These early DHCP DISCOVER packets were dropped by the router potentially
causing a big delay until the client started a new attempt. Unnecessary long
network boot-up delays were observed with at least the lwip run script and
Sculpt on the PinePhone and could be tracked down to this former
inconsistency in the router.

This commit fixes the inconsistency.

The new 'Dictionary' provides an easy way to access objects using
strings as key. The 'String' received the 'operator >' to simplify the
organization of strings in an AVL tree.

The patch removes the former definition of the 'operator >' from the
platform driver because it would be ambigious now.

907641f6ea lx_fs: improve safety when using dir handles
This patch consolidates the repetitive error handling across the RPC
functions, which take node handles or directory handles as arguments.

During this change, I noticed that directory handles - which are values
provided by the client - were not checked for their type before being
used. A misbehaving client may open a file, manually construct a
directory handle using the number of the file handle, and invoke a
directory operation at lx_fs, which would then wrongly access a file
node as directory node.

This patch solves this issue by introducing two distinct methods
_with_open_node and _with_open_dir_node, which perform the respective
safety checks.

79cc9af212 nic_router: intf. con/destruct reports link state
Creating and destructing an interface was not considered a change of its real
link state as defined in the description of the <report link_state_triggers="">
config attribute in the router's README. In case of Uplink sessions this is
obviously a problem as they communicate their real link state through session
lifetime. But also in case of NIC sessions it's a possible to create an
interface that is immediately "up" after creation or destruct an interface
without its link state going "down" beforehand.

Taking into account also the practical application of the
<report link_state_triggers=""> attribute, reporting only on destruction and
construction of interfaces that are "up" seems shorthanded. This is because a
report-receiver most likely needs to be able to synchronize the lifetime of
the objects that keep track of the link states with the lifetime of the
corresponding sessions.

That said, with this commit, the router triggers a report update on each
session construction/destruction when <report link_state_triggers=""> is
set.

aff1db1543 nic_router: generate reports asynchronously
The NIC router used to generate reports triggered by IP config changes or link
state changes synchonously, i.e., inline with the activation context that
caused the change. This has two disadvantages. First, it can lead to an
excessive number of report updates in situations with quick bursts of
triggering changes. In such situations it is preferable to collect the changes
and reflect them with only one final report update.

Second, synchronous reporting may happen while the router is in a state that
leads to an incorrect report (e.g. during reconfiguration). To prevent this
from happening, the router so far explicitely switched off reporting when
entering incoherent states and back on when leaving them. However, this
solution is error-prone as the exclusion windows must be maintained manually.

Both issues can be solved by not directly generating a report when necessary
but instead submitting a signal and letting the signal handler do the work in
a dedicated activation context.

cc9368ccb4 os: add File_system_session::num_entries RPC
This patch splits the querying of the number of directory entries from
the directory's 'status' information. Subsuming the number of directory
entries as part of the status makes 'stat' calls too costly for some
file systems that need to read a directory for determining the number of
entries. So when stat'ing the entries of one directory that contains sub
directories, all entries of each sub directory are visited.

Thanks to Cedric Degea for pointing out this performance bottleneck!

With this change, the 'status' function returns a 'Status::size' value
of 0 when called for a directory handle.

b82d83e271 nic_router: handle bad DNS in DHCP ACK gracefully
The DHCP client of the NIC router used to end up in an uncaught exception if
an IP address in the DNS server option of a DHCP ACK was invalid. This commit
makes the 'Dns_server' constructor (where the exception originated from)
private and instead introduces a public lambda method 'construct' that calls
one lambda argument on success and another on failure. This is also in line
with the most recent changes to the 'find_by_*' methods of other classes in
the NIC router and contributes to the goal of reducing expensive exception
handling.

054990aafa nic_router: fix net session aliases
The Interface class of the router is an abstraction for NIC client sessions,
NIC server sessions, and Uplink sessions. Nonetheless, Interface generally used
to use the packet stream types of the Nic namespace and it worked because the
Uplink packet stream types are factually the same (the are typedef'd from the
same base type templates with the same parameters).

The initial intention of this issue was to remove dependency on the diverse
packet stream stream types from Interface. However, this turned out to be more
tricky than thought. The Interface class calls function templates on the packet
stream types, making a generic virtual interface impossible. And moving the
calling code to the session classes as well would produce a lot of redundancy.

Therefore, this commit removes only the use of the Nic namespace in the
interface.* files by typedef'ing the packet stream types from the generic
Genode type templates with the same parameters as in Nic and Uplink.

7d143087c9 xml_node: change with_sub_node signature
The `with_sub_node` method is renamed to `with_optional_sub_node` to
better reflect that the non-existence of a sub node with the desired type is
ignored.
At the same time, the new `with_sub_node` now takes a second functor that is
called when no sub node of the desired type exists.
