Since we can't get rid of all unmet dependencies (at least not in every
possible plugin configuration) the message is more confusing than
helpful. In particular because a detailed warning about plugin features
that failed to load due to unmet dependencies is only logged on level 2.
Some tokens might not fail when creating EC public keys in the incorrect
format, but they will later not be able to use them to verify signatures.
References #872.
Some CAs don't use SHA-1 hashes of the public key as subjectKeyIdentifier and
authorityKeyIdentifier. If that's the case we can't force the
calculation of the hash to compare that to authorityKeyIdentifier in the CRL,
instead we use the subjectKeyIdentifier stored in the issuer certificate, if
available. Otherwise, we fall back to the SHA-1 hash (or comparing the
DNs) as before.
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).
While these files are generated they don't really change and are not
architecture dependant. The previous solution prevented cross-compilation
from the repository as `bliss_huffman` was built for the target system but
was then executed on the build host to create the source files, which
naturally was bound to fail.
The `recreate-bliss-huffman` make target can be used inside the bliss
directory to update the source files if needed.
Fixes#812.
While it is currently unclear why it happens, canceling threads waiting in the
new_query condvar does not work as expected. The behavior is not fully
reproducible: Either cancel(), join() or destroying the condvar hangs.
The issue has been seen in the http-fetcher unit tests, where the stream service
triggers the use of the resolver for "localhost" hosts. It is reproducible with
any cleanup following a host_create_from_dns() use on a Ubuntu 14.04 x64 system.
Further, the issue is related to the use of libunwind, as only builds with
--enable-unwind-backtraces are affected.
As we broadcast() the new_query condvar before destruction, a hard cancel() of
these threads is actually not required. Instead we let these threads clean up
themselves after receiving the condvar signal.
Unloading libraries calls any library constructor/destructor functions. Some
libraries can't handle that in our excessive unit test use. GnuTLS leaks
a /dev/urandom file descriptor, letting unit tests fail with arbitrary
out-of-resources errors.
As we now use the same reqid for multiple CHILD_SAs with the same selectors,
having marks based on the reqid makes not that much sense anymore. Instead we
use unique marks that use a custom identifier. This identifier is reused during
rekeying, keeping the marks constant for any rule relying on it (for example
installed by updown).
This also simplifies handling of reqid allocation, as we do not have to query
the marks that is not yet assigned for an unknown reqid.
