While trap and regular policies now often look the same (mainly because
reqids are kept constant) trap policies still need to have a lower priority
than regular policies to handle unroute/route correctly if e.g. IPComp
is used or the mode changes. But if we use a completely different
priority range that's lower than that of regular policies it is not possible
to install overlapping trap policies. By differentiating trap from
regular policies via the priority's LSB this issue is avoided while
still maintaining the proper ordering of trap and regular policies.
Fixes#1243.
If charon.prefer_configured_proposals is disabled select() is called on
the received proposal. This incorrectly set the SPI to 0 as the
configured proposal has no SPI set.
Fixes#2190.
The Optimistic Duplicate Address Detection (DAD) seems to fail in some
cases (`dadfailed` in `ip addr`) rendering the virtual IP address unusable.
Fixes#2183.
This implements rule 6 of RFC 6724 using the default priority table,
so that e.g. global addresses are preferred over ULAs (which also have
global scope) when the destination is a global address.
Fixes#2138.
By default, the kernel incorrectly uses an 8 byte alignment, which is
mandatory for IPv6 but prohibited for IPv4. For many algorithms this
doesn't matter but that's not the case for HMAC_SHA2_256_128.
Since 2.6.39 the kernel can be explicitly configured to use a 4 byte
alignment.
Otherwise, we'd end up with an empty TS list, which is not valid.
Because end->tohost is set to !end->subnets in starter the removed branch was
never used.
The Python VICI library does not check if the socket is closed.
If the daemon closes the connection, _recvall() spins forever.
Closesstrongswan/strongswan#56.
Recent research demonstrates that at least for 1024-bit DH groups, it is
possible to create specially crafted primes having a backdoor. From the
prime itself this is not detectable, creating a perfect NOBUS attack.
http://eprint.iacr.org/2016/961
For the primes defined in RFC 5114 no information is provided on how these
have been selected. In the default proposal we included one of the 2048-bit
primes only, where it is questionable if constructing a backdoored prime is
feasible. Nevertheless, this patch removes the group from the set of default
proposals as well.
The log level was incorrectly set to the same value for all groups.
Fixes: dac15e03c8 ("bus: Fix maximum log levels when mixing log/vlog
implementing loggers")
Fix for "Permission denied (you must be root)" error when calling
iptc_init(), which opens a RAW socket to communicate with the kernel,
when built with "--with-capabilities=libcap".
Closes strongswan/strongswan#53.
Fixes#2157.
A wrong variable is used (route instead of best), so much that the
returned interface belongs to the last seen route instead of the best
choice route.
get_route() may therefore return mismatching interface and gateway.
Fixes: 66e9165bc6 ("kernel-netlink: Return outbound interface in get_nexthop()")

We parse aes*gmac as encryption algorithm, which we have to map to an
integrity algorithm. We also make sure we remove all other encryption
algorithms and ensure there is an integrity algorithm.
