304cb290d9 nic_router: rework quota accounting
* 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)

bd77bb41df nic_router: improve handling of TCP termination
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.

d6c6549354 nic_router: destroy links on insufficient resource
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.

d909715f1b input/ps2: drop fake right-shift scancodes
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.

7e08bba25c Cached_fs_rom: fix congestion error
When the cached_fs_rom saturates the packet stream of its File_system
session it will call the session request handler recursively as pending
transfers are completed. This is bad because the content of the XML node
currently being processed will change.

The session request handler can no longer be called directly, but the
"schedule" method will submit a signal to the request handler, and
requests will be processed after the current operation has completed.

Calling 'handle_io_response()' in a regular VFS function (in contrast to a
post-signal hook) can cause problems if the caller of the VFS function holds
a lock which prevents the io response handler from returning.

With this commit, the user of the VFS becomes responsible for unblocking
threads which might be blocking after a failed 'queue_read()', 'queue_sync()'
or 'write()' call.

59ac5b10c7 Plugin for importing VFS content

moment the copying of symlinks is not enabled, and the resources
obtained by the import file-system may not be freed after the import is
finished.

4b46abf813 base: rm first-class support for static binaries
This patch removes the detection of statically linked executables from
the base framework. It thereby fixes the corner cases encountered with
Sculpt when obtaining the binaries of the runtime from the depot_rom
service that is hosted within the runtime.

Statically linked binaries and hybrid Linux/Genode (lx_hybrid) binaries
can still be started by relabeling the ROM-session route of "ld.lib.so"
to the binary name, pretending that the binary is the dynamic linker.
This can be achieved via init's label rewriting mechanism:

  <route>
    <service name="ROM" unscoped_label="ld.lib.so">
      <parent label="test-platform"/> </service>
  </route>

However, as this is quite cryptic and would need to be applied for all
lx_hybrid components, the patch adds a shortcut to init's configuration.
One can simply add the 'ld="no"' attribute to the <start> node of the
corresponding component:

  <start name="test-platform" ld="no"/>

3bbeacad20 init: preserve final state of exited children
This is a follow-up patch of "init: avoid too eager child restart". On
each config update of init, init re-applies child-specific configuration
changes. In the case of an already exited child, this re-evaluation
wrongly marked such a child as abandoned because the child's environment
sessions do no longer exist. Abandoning the child, in turn, triggers the
destruction and subseqent restart (because the <start> node of the
configuration still exists). The latter is bad for two reasons.

First, the exit state of the original instance becomes lost. Second, the
restart may have unexpected side effects due to sessions created by the
new instance. I.e., when resizing a partition in sculpt, init would
wrongly restart the gpt-write tool after the tool successfully exited.
This collides with a newly started instance of part_blk/resize2fs, which
now competes with the second gpt-write instance for the exclusive access
of the targeted block device.

The patch prevents init from re-applying configurations to exited
children. The accompanied test case covers the corner case.

49a3a0e0d0 nic_router: multiple uplinks
Introduce the uplink tag:

! <config>

!    <uplink label="wired" domain="wired_bridge">
!    <uplink               domain="wired_bridge">
! <config/>

For each uplink tag, the NIC router requests a NIC session with the
corresponding label or an empty label if there is no label attribute.
These NIC sessions get attached to the domain that is set in their
uplink tag as soon as the domain appears. This means their lifetime is
not bound to the domain. Uplink NIC sessions can be safely moved from
one domain to another without being closed by reconfiguring the
corresponding domain attribute.

Attention: This may render previously valid NIC router configurations
useless. A domain named "uplink" doesn't automatically request a NIC
session anymore. To fix these configurations, just add

! <uplink domain="uplink"/>

or

! <uplink label="[LABEL]" domain="uplink"/>

as direct subtag of the <config> tag.

6491ba0589 init: avoid too eager child restart
This patch weakens the aggressive restart of a child with incomplete
environment sessions. The restart check is performed each time
the init configuration changes. In sculpt, this is not a rare special
case anymore but a frequent case when using the depot_rom as provider
for environment ROM sessions. In particular when starting a chain of
inter-depending children, the sculpt-manager quickly generates a
sequence of configurations with successively added start nodes.

97ea513122 nic_router: fix pure virtual call in ~Interface()
The interface destructor called pure virtual methods at least when
cancelling ARP- waiting states. The implementations were made by the
deriving classes Session_component respectively Uplink. This led to an
abort of the NIC router as the destruction of the derived class was
already done. A similar problem already occured in the past during the
construction of Interface and was back then solved by introducing a
separate init() method. This commit, however, solved the problem by
making Interface a member of the other classes. Therefore, the init()
method could be removed again. Furthermore, the interface polica could be
moved from Session_component_base to Session_component. The commit also
had to generalize the way the link state of an interface is determined.

b96f0fa2df init: defer immediate restart of abandoned child
While a child is abandoned, we must limit the start of anothers with
the same name. Otherwise - of the child has startup problems - a number
of abandoned children with the same name may queue up. This becomes a
problem whenever the child destruction depends on an asynchronous
service that provides an env session for the children. If the service is
unable to keep up with the session requests (both create and close),
the queue of abandoned children becomes unbounded. Limiting the child
creation rate to one abandoned child per name mitigates this problem.

4630c4b9ff nic_router: fix domain invalidation during init
Previously we were doing the initialization once over all domains,
remembered which of them became invalid and destroyed those afterwards.
This isn't sufficient. As soon as one domain becomes invalid we have to
dissolve/destroy this one, deinitialize all other domains again (as they
could contain references to the invalid domain) and retry to initialize
them from the beginning. We proceed with this until we have one run
without a domain becoming invalid. Then we can be sure that the last
initialization run did not create references to any invalid domain.

I doubt that use cases exist where the inital empty-report mimic is

ba348b73e2 nic_router: re-use dynamic IPv4 config if possible
When re-configuring the NIC router, determine for each domain if at least one
interface stays with the domain. If a domain fullfills this and has a
dynamic IP config (received via a DHCP client), keep the IP config.

To achieve this, the following changes have been made to the existing NIC
router code:

* Split-up Interface::handle_config into three steps:

  1) Determine for each interface if its domain can keep its IP config or
     or if it has to mark it invalid. This must be done before (re-)attaching
     any interface because during "attach" several decisions are made based on
     the validity of the IP config of corresponding the domain.
     (E.g. whether to participate in sending DHCP DISCOVERs {IP config
     invalid} or whether to participate in sending pending ARP REQUESTs
     {IP config valid} ).

  2) Detach, attach, or re-attach each interface according to the
     configuration. This must be done before re-considering the temporary
     state objects of each interface because the latter might have effects
     on the interfaces of remote domains which must then be in place already.

  3) Re-consider temporary state objects of each interface. (E.g. transport
     layer connection states)

* Re-work IP-config setter in a way that it works as follows:

  1) If the old IP config is valid, let all local interfaces as well as remote
     interfaces that depend on the IP config of the domain detach from the old
     IP config.

  2) Overwrite with new IP config

  3) If the new IP config is valid, let all local interfaces as well as remote
     interfaces that depend on the IP config of the domain attach to the new
     IP config.

ce57319e4b nic_router: bind uplink session lifetime to domain
Normally, the NIC sessions are independent from the domain tags.
However, by now the uplink session, in contrast to the sessions of the
other domains, is still not a server but a client. This means that only
the NIC router itself can decide when to open and close uplink sessions
and how many. Thus, with this commit, we break with the pattern that
session lifetime is independent from domains by letting the NIC router
create the uplink session when the uplink domain appears and close the
session when the domain disappears.

7085640f05 nic_router: remove 'mac_first' attribute
Since the router MAC is allocated like the donwlink MACs it can't happen
anymore that these MACs clash, for instance due to nested routers. Thus,
the range of the MAC allocators of nested routers must not be exclusive
anymore which deprecates the 'mac_first' configuration attribute.

41dbad13e4 nic_router/nic_bridge: re-work Mac_allocator
The old MAC allocator had several drawbacks:

* the address base was a public static that could and must have been written
  directly from outside the class
* the in-use-flag array was based on unsigned values consuming 4 bytes each
  for only one bit of information
* it was a public header that we actually don't want to expose to all
  components but only to the few networking components
* it used the not-so-safe bit notation for integer members of GCC

The new version fixes all these drawbacks.

980f3e9c5c net: use Size_guard for packet-data accessors
Instead of handing over the maximum available size to the packet data
accessors, hand over a size guard that keeps track of the packets
boundaries.

This commit also moves the size-guard utilitiy header of Ping and NIC
Router to the include/net directory making it a part of the net library.
It applies the new approach to all net-lib users in the basic repositories.

Ping looses its configurability regarding the ICMP data size as this would
require an additional method in the size guard which would be used only by
Ping.

The size guard was also re-worked to fit the fact that a packet can
bring a tail as well as a header (Ethernet).

11a297b557 net: consider tail of Ethernet frame
The Ethernet payload may be followed by padding of variable length and
the FCS (Frame Check Sequence). Thus, we should consider the value
"Ethernet-frame size minus Ethernet-header size" to be only the maximum
size of the encapsulated IP packet. But until now, we considered it to
be also the actual size of the encapsulated IP packet. This commit fixes
the problem for all affected components of the Genode base-repository.

373134c4e7 net: safer access to packet data
Replace packet method 'T *data' by the new methods 'T &reinterpret_data'
for parsing or modifying existing sub-protocol packets and 'T
&construct_at_data' for composing a new sub-protocol packet. This has
the advantage that, when composing a new packet, the default constructor
that zero-fills the packet is always called first.

6389434222 input_filter: rm input selection in output node
This patch largely reverts the feature of selecting parts of input nodes
from within the output node (as originally introduced by commit
7263cae5a18b4f1f2293d031f9bafcf05ba51146). The selection of content
should be consistently performed by input nodes instead. The principle
ability of copying input nodes verbatim into the output stays available.

1f1302e185 terminal: use VFS-based font handling
This patch replaces the terminal's formerly built-in fonts with the new
VFS-based font handling.

To avoid the copying of the terminal's font configuration across run
scripts, this patch adds the new terminal/pkg runtime package, which
includes everything needed for instantiating a terminal: the actual
terminal component, the library dependencies (vfs_ttf, which in turn
depends on the libc), a font (bitstream-vera), and a reasonable default
configuration.

6a12a6b4ba vfs: reduce ROM-update rate Rom_file_system::stat
The 'stat' method is called for all paths, not just the specific file
system node of the ROM module. The ROM update is needed only in the
latter case.

Otherwise, when always updating the ROM on stat, stat calls on the VFS
become very expensive in the presence of a mounted ROM module if the ROM
is obtained from fs_rom (which re-watches the file and all its
individual path elements whenever the 'update' RPC function is called).
