For reading the MAC address we try first to read it from the <policy> tag, and
when it is not defined in the <policy> tag, we allocate a MAC. But there was
no handling of the case that there is no appropriate <policy> tag. In this
case we want to create the session with an allocated MAC also.
This patch makes init robust against invalid routing rules that lack a
name attribute in the '<service>' node. This situation may occur when
interactively editing routes in Sculpt.
Some application code is dereferencing the pointer returned by
'packet_content' at packet streams without checking that it is valid.
Throw an exception rather than return a null pointer, except for
zero-length packets, which have somewhat implicit invalid content and
that we believe to be properly handled in all current cases.
The client-side of a packet stream cannot take corrective action if the
server-side is sending packets with invalid content, but the servers
that provide packet streams should catch this exception to detect
misbehaving clients.

Change the root of a session request into an explicit path and apply the
label-to-path conversion using the "path_prefix" policy attribute. This
is in addition to only applying a root change with a "path" attribute.

* Account all RAM/CAP quota of a session except quota for metadata used in
core. The latter is considered when asking if a session can afford to make
an operation but it does not get accounted to always be able to pay back all
quota when a session closes. The general accounting mechanism is moved from
atop of the allocators down to the level of RAM/RM session operations.
* report statistics about session objects and quota if <report stats="yes"
quota="yes"/> is configured. (default is yes if <report> is present)
Issue #2953
Like suggested by RFC 2663, reprogram the dissolve timeout of a TCP link
state to 2 times the maximum segment lifetime (by default 1 minute) when
receiving a matching packet with the FIN flag set, or with the ACK flag
set to acknowledge a FIN of the remote side.
Mark a link state as closed (no further reprogramming of the dissolve
timeout) and set the dissolve timeout to 2 times the maximum segment
lifetime when receiving a packet with the RESET flag set.
Issue #2953
If the NIC router has insufficient CAP or RAM quota for the creation of
a state object for an interface, it tries to destroy a certain amount of
existing state objects of this interface to free resources. Afterwards,
it retries handling the current packet once. If it does fail again, the
router drops the packet.
Issue #2953
Ensure that a '\0' always appears at the end of the ouput of the XML
generator. Previously, exceptions during the Node(...) constructor
might have prevented this. This commit also extends the xml_generator
test to drive a harder test on exceptions in the Xml_generator.
Issue #2953
The VFS server does not support file-system with one single-file plugin
providing the root. This is because the "leaf_path" is not universally
implemented to handle the path "/". This fix is simply to skip a
"leaf_path" check when opening the path "/".

The PS/2 driver retries to get mouse-reset results for 700 ms, sleeping
after each attempt for 10 ms. So, the driver needs a Timer session now.
Fixes#2713
This patch addresses a situation where _process_packets was called as a
side effect of watch notification (that was processed during an unlink
RPC operation). This scenario (triggered by the fs_query test)
ultimately ended up in a deadlock. Io/watch reponse handlers should
never re-enter the application logic.
The new base/xsd/config.inc defines generic XSD types such as 'Boolean' or
'Session_label'. It can be included in config XSD files by using:
! <xs:include schemaLocation="file://${GENODE_CONFIG_INC}"/>
The string ${GENODE_CONFIG_INC} is replaced by the run tool with the
above mentionened file path.
Issue #2897
Seen on X250
Description from https://www.win.tue.nl/~aeb/linux/kbd/scancodes-1.html
The ten grey keys Insert, Home, PgUp, Delete, End, PgDn, Up, Left,
Down, Right are supposed to function regardless of the state of Shift
and NumLock keys. But for an old AT keyboard the keypad keys would
produce digits when Numlock was on or Shift was down. Therefore, in
order to fool old programs, fake scancodes are sent: when LShift is
down, and Insert is pressed, e0 aa e0 52 is sent; upon release of
Insert e0 d2 e0 2a is sent. In other words, a fake LShift-up and fake
LShift-down are inserted.
Fixes#2888
