Optionally with "dynamic" traffic selectors resolved. A new method
is added for those cases where we actually want to select potentially
narrowed traffic selectors using a supplied list. The latter now also
always logs details, while the former does not.
Previously, the logger installed by the controller always announced
LEVEL_PRIVATE(4), which produced completely useless logging calls with
the common clients (vici/stroke) whose default log level is LEVEL_CTRL(1).
This can produce quite some overhead if there are e.g. a lot of concurrent
initiate() calls.
mallinfo() is deprecated because it uses `int` for the members of the
returned struct, whereas mallinfo2() uses `size_t`. It's available
since glibc 2.33.
While combining the actions could cause duplicates (while the SA is
initiated, traffic might trigger the trap and the initiation of another
CHILD_SA), the previous commit should avoid most duplicates. If reuse_ikesa
is disabled, duplicates can't be prevented, though.
This avoids having to register certificates with authority/ca backends
beforehand, which is tricky for intermediate CA certificates loaded
themselves via authority/ca sections. On the other hand, the form of
these URLs can't be determined by config backends anymore (not an issue
for the two current implementations, no idea if custom implementations
ever made use of that possibility). If that became necessary, we could
perhaps pass the certificate to the CDP enumerator or add a new method
to the credential_set_t interface.
If the key type was specified but the ID was NULL or matched a subject, it
was possible that a certificate was returned that didn't actually match
the requested key type.
Closesstrongswan/strongswan#141.
Although being already logged on level 2, these messages are usually just
confusing if they pop up randomly in the log when e.g. querying the configs
or installing traps. So after this the log messages will only be logged when
actually proposing or selecting traffic selectors during IKE.
Reqids for the same traffic selectors are now stable so we don't have to
pass reqids of previously installed CHILD_SAs. Likewise, we don't need
to know the reqid of the newly installed trap policy as we now uninstall
by name.
If users want to associate secrets with any identity, let 'em. This is
also possible with vici and might help if e.g. the remote identity is
actually %any as that would match a PSK with local IP and %any better
than one with local and different remote IP.
Fixes#2497.
This way updates to the mediation config are respected and the order in
which configs are configured/loaded does not matter.
The SQL plugin currently maintains the strong relationship between
mediated and mediation connection (we could theoretically change that to a
string too).
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.
This also restores the charon.signature_authentication_constraints
functionality, that is, if no explicit IKE signature schemes are
configured we apply all regular signature constraints as IKE constraints.
