New versions of Bind limit the maximum UDP message size to 1232 bytes,
which is the same that newer versions of libunbound propose as maximum via
EDNS in requests, so increasing the limit on the server wouldn't help.
Instead we allow DNS via TCP so the client can switch after receiving the
truncated UDP response.
This also restores the test as it was before the referenced commit so it
again, as written in the description, demonstrates that venus is unable
to ping sun without IPsec tunnel.
Fixes: f27fb58ae0 ("testing: Update description and test evaluation of host2host-transport-nat")
Note that the mobike-nat test has been removed as it basically did the same
as the mobike-virtual-ip-nat test. Instead, the mobike-nat-mapping scenario
is added, which simulates a NAT router restart.
For documentation purposes the new folders ikev1-algs, ikev2-algs,
ikev1-multi-ca and ikev2-multi-ca have been created. Most of the
test cases have now been converted to the vici interface. The
remaining legacy stroke scenarios yet to be converted have been put
into the ikev2-stroke-bye folder.
For documentation purposes some legacy stroke scenarios will be kept
in the ikev1-stroke, ikev2-stroke and ipv6-stroke folders.
To align with RFC 4519, section 2.31/32, the abbreviation for surname
is changed to "SN" that was previously used for serialNumber, which does
not have an abbreviation.
This mapping had its origins in the X.509 patch for FreeS/WAN that was
started in 2000. It was aligned with how OpenSSL did this in earlier
versions. However, there it was changed already in March 2002 (commit
ffbe98b7630d604263cfb1118c67ca2617a8e222) to make it compatible with
RFC 2256 (predecessor of RFC 4519).

Also includes some changes for jessie's version of FreeRADIUS 2 (was
previously a custom version).
Besides the move to a subdir the config files were adapted for 3.0.
The rlm_sim_files module was removed with FreeRADIUS 3 and Debian's
package of FreeRADIUS 2 does not ship it, so we now replicate it using
the files module (via users file, which is actually a symlink to
mods-config/files/authorize in the default installation of FreeRADIUS 3).
Another approach was tried using rlm_passwd, however, that module does
not read binary/hex data, only printable strings, which would require
changing the triplets.
For 2.x a hack in the site config is necessary to make the attributes
available to the EAP-SIM module.
The client identifier serves as unique identifier just like a unique MAC
address would, so even with identity_leases disabled some DHCP servers
might assign unique leases per identity.
DHCP servers will respond to port 67 if giaddr is non-zero, which we set
if we are not broadcasting. While such messages are received fine via
RAW socket the kernel will respond with an ICMP port unreachable if no
socket is bound to that port. Instead of opening a dummy socket on port
67 just to avoid the ICMPs we can also just operate with a single
socket, bind it to port 67 and send our requests from that port.
Since SO_REUSEADDR behaves on Linux like SO_REUSEPORT does on other
systems we can bind that port even if a DHCP server is running on the
same host as the daemon (this might have to be adapted to make this work
on other systems, but due to the raw socket the plugin is not that portable
anyway).
