We already do this in the trusted public key enumerator (which
internally uses the trusted certificate enumerator) but should do so
also when this enumerator is used directly (since the public key
enumerator has the read lock the additional call will just be skipped
there).
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.
The certificate_printer class allows the printing of certificate
information to a text file (usually stdout). This class is used
by the pki --print and swanctl --list-certs commands as well as
by the stroke plugin.
This is particularly important for single valued rules (e.g.
identities). When copying values this is already handled correctly
by the enumerator and add().
Not sure if defining multiple CA constraints and enforcing _all_ of them,
i.e. the previous behavior, makes even sense. To ensure a very specific
chain it should be enough to define the last intermediate CA. On the
other hand, the ability to define multiple CAs could simplify configuration.
This can currently only be used with swanctl/VICI based configs as `rightca`
only takes a single DN.
There is a similar function to map key_type_t and hasher_t to an OID,
but this maps schemes directly (and to use the other function we'd
have to have a function to map schemes to hash algorithms first).
Additionally generate SHA-1 fingerprints of raw BLISS subjectPublicKey
and subjectPublicKeyInfo objects.
Some basic functions used by the bliss_public_key class are shared
with the bliss_private_key class.
Previously we got no reference to the cached issuer certificate
before releasing the lock of the cache line, this allowed other
threads, or even the same thread if it replaces a cache line, to
destroy that issuer certificate in cache() (or flush()) before
get_ref() for the issuer certificate is finally called.
Due to the issue described in c641974, purge() inadvertently destroyed
CA certificates that should have been kept (while the pointer to these
objects remained in the array). This lead to incorrect reference counts
and after a few reauthentications with multiple authentication rounds,
which cause calls to purge(TRUE), to crashes.
This won't hurt as long as sets and validators are of the same class.
But as soon as one of the object's class is changed this will cause
either a compile error (best option), or result (most likely) in a
crash.
