c8a8cbd7be run/tz_vmm: fix deprecated use of board specs
Filtering boards in a run script by specs isn't the right way anymore (the
specs do not exist anymore). Nowadays, we have to use [have_board] instead.

00e8e363d8 run/tz_vmm: fix broken network test
For unknown reasons, the former 'wget genode.org' call, that was meant to test
network in the Trustzone guest on imx53_qsb_tz, didn't succeed anymore although
the same call succeeded on my Sculpt VM Linux. However, 'ping 1.1.1.1' still
works, so, the script now uses this as test for networking instead.

8bc861ca71 nic_router: do not re-use ARP request as reply
So far, in order to create an ARP reply, the NIC router merely created a copy
of the corresponding ARP request and modified only those values that differ.
This approach has the disadvantage of re-using bad parameters from a broken
request. The specific use-case that made this visible was an early version of
the Pine board network driver that used to forward ARP requests with a greater
size than required. The ARP replies of the router re-used this size and
confused other network nodes with that. In general, the NIC router should
rely on the data of incoming packets the least possible. Therefore, with this
commit, the router creates a new ARP reply from scratch and uses only those
values required from the corresponding ARP request.

9384e075cb ipv4: get rid of C++ bitsets, add DF/MF flags
The former declaration of the IPv4 packet did not only use the questionable
tool of implementation-defined C++ bitsets but also lacked access to flags
"don't fragment" (DF) and "more fragments" (MF). This commit replaces the
C++ bitsets by using the register framework and introduces accessors for the
missing flags.

1a526e73a3 dde_linux: introduce new lx_emul/lx_kit library
The re-newed approach currently supports ARM 64-bit only.
It depends on the Platform API of the ARM architecture.
It tries to meet the original semantic of the Linux kernel
functions as far as possible. To achieve this, device drivers
using this library should reference the original Linux kernel
headers at foremost. Only the headers in `src/include/lx_emul/shadow`
have to shadow clone the original ones.

1aba330ae6 dde_linux: fix packet size calc. of Nic drivers
skb_push() already increases the skb->len by ETH_HLEN, hence adding
ETH_HLEN to the packet_size is redundant.

A too large packet size becomes a problem for large MTUs. With a maximum
MTU of 1500, adding ETH_HLEN twice will lead to a packet size of 1528.
Since this is larger than what we expect for good-old Ethernet (max. 1522),
some clients (e.g. the e1000 model in vbox5) may drop these packets.

5138aeba80 libc: fix nested monitor call in 'symlink'
The symlink implementation wrongly constructed a 'Sync' object within
the context of a monitor call. The 'Sync' constructor indirectly
depended on libc I/O for obtaining the current time, ultimately
resulting in a nested attempt of a monitor call. This could be
reproduced via the base.run script:

  $ cd /home
  $ ln -s a b

The 'ln' command resulted in the following log message:

  [init -> /bin/bash -> 7] Error: deadlock ahead, mutex=0x10ff8c70, return ip=0x500583a7

The patch fixes the problem by splitting the single monitor call into
two monitor calls and moving the construction of the 'Sync' object
in-between both monitor calls, thereby executing the constructor at the
libc application level.

688379d1ed sel4: fix segmentation fault with CCACHE=yes
Building the elfloader in kernel-sel4.inc has a problem with Genodes CCACHE
make variable. When issuing ...

! ./tool/depot/create mstein/bin/*/base-sel4-* CCACHE=yes

..., building the elfloader used to consume all memory of the host system and
then run into a segmentation fault:

! make[6]: *** [elfloader/elfloader.o] Segmentation fault (core dumped)

This is because the other build system invokes the CCACHE variable as a command
in front of the compiler command. If CCACHE is set to 'yes', the 'yes' command
is called and produces an endless output into some output file. The problem
can be fixed by locally re-setting the CCACHE variable for the
'make ... elfloader' command to 'ccache' (Genode CCACHE==yes) or '' (Genode
CCACHE!=yes).

2d017ad7b7 nic_router: guard against exception in free_ip
Adds try-catch-statement with diagnostic errors in Dhcp_server::free_ip in
order to guard against exceptions from the underlying bit allocator. These
exceptions should never happen given that the router is programmed correctly
and always feeds Dhcp_server::free_ip with sane arguments (which it should).
However, should this not be the case, we can assume that the failed IP freeing
indicates that the IP isn't allocated anyway and it's fine to continue using
the router. Furthermore, IP allocations are a mere client service and not
relevant for the integrity or safety of the router.

be644098d7 nic_router: fix exc. in Interface::handle_config_3
When Interface::handle_config_3 (third step of applying a new configuration to
interfaces) tried to detach the interface from the current IP config because
the old and new IP config differed, it did so using the new domain. The former
steps of the reconfiguration already installed the new domain reference at the
interface. Therefore, also the DHCP server of the new domain was used. This,
however caused uncaught exceptions because detaching from an IP config
includes dissolving all DHCP allocations. This dissolving of DHCP allocations
now operated on a DHCP server (the one of the new domain) that wasn't related
to the allocations and, in the worst case, caused an uncaught exception
because the IPs were out of its range.

That said, this commit ensures that detaching an interface from an IP config
is always done on the domain from which the IP config originated. Normally,
this is the domain the interface is attached to. But in the case of
Interface::handle_config_3, it is another - the former domain the interface
was attached to.

The commit also adapts the nic_router_dhcp_* tests in a way that they
reconfigure the router in a way that would trigger the uncaught exception
without the fix.

Adapts Dir_file_system::open_composite_dirs in a way that it returns "success"
when the leaf node of the path is an empty directory but "lookup failed", as
usual, if one of the other directories on the way to the leaf node is empty.

I couldn't find a technical reason why we used to return "lookup failed" when
only the leaf node was empty.

The commit also adds a test for en empty root directory and empty
sub-directories to the fs_query run script.
