zone_needdump() could potentially not call zone_settimer() so
explitly call zone_settimer() as zone->resigntime could have
gone backward.
(cherry picked from commit 5ec57f31b0)
With RRSIG records no longer being signed with the full
sig-validity-interval we need to ensure the zone->resigntime
as it may need to be set to a earlier time.

The downstream distributors of BIND 9 (Debian in this case) are in
process of removing xml2-config command from the libxml2-dev package
(see Debian Bug #949056 for details). The removal of the script will
make BIND 9 to fail to build from the source when --with-libxml2=yes is
specified or not link with libxml2 when --with-libxml2=auto is specified
and then fail ABI changes (Debian Bug #949056).
When --with-libxml2=<path>, the script checks for <path>/bin/xml2-config
and uses the specified path to link with libxml2. This has been kept to
retain backwards compatibility with systems that does not ship
pkg-config.
* CKR_CRYPTOKI_ALREADY_INITIALIZED: This value can only be returned by
`C_Initialize`. It means that the Cryptoki library has already been
initialized (by a previous call to `C_Initialize` which did not have a
matching `C_Finalize` call).
* CKR_FUNCTION_NOT_SUPPORTED: The requested function is not supported by this
Cryptoki library. Even unsupported functions in the Cryptoki API should have a
"stub" in the library; this stub should simply return the value
CKR_FUNCTION_NOT_SUPPORTED.
* CKR_LIBRARY_LOAD_FAILED: The Cryptoki library could not load a dependent
shared library.

The OASIS pkcs11.h header has a restrictive license. Replace the
pkcs11.h pkcs11f.h and pkcs11t.h headers with pkcs11.h from p11-kit.
For source distribution, the license for the OASIS headers itself
doesn't pose any licensing problem when combined with MPL license, but
it possibly creates problem for downstream distributors of BIND 9.

* ctx needs to be destroyed before it is regenerated.
* emit the name of the signature to be replaced.
* cleanup memory before asserting so post longjump doesn't detect a
memory leak.
* comment code.

BSD sed does not recognize \s as a whitespace matching token. Make the
sed script in doc/arm/Makefile.in which ensures GitLab identifiers are
not split across lines portable by replacing \s with [[:space:]].

Artifacts generated by the docs:sid:amd64 job need to be retained longer
than for other jobs as they are used for building bind.isc.org contents.
If these artifacts are removed too quickly, pipelines in the pages/bind
GitLab project start failing, preventing content updates from being
published. Increase lifetime of the relevant job artifacts to prevent
this from happening.

Submissions to Coverity Scan should be limited to those originated from
release branches and only from a specific schedule which holds
COVERITY_SCAN_PROJECT_NAME and COVERITY_SCAN_TOKEN variables.
(cherry picked from commit 48530aa21395414b0f9788ea5ab158b2b09ab977)
This job requires two CI variables to be set:
- COVERITY_SCAN_PROJECT_NAME: project name, which is associated with
the BIND branch for which this job is executed, e.g. "bind-master",
- COVERITY_SCAN_TOKEN: project token.

The memory ordering in the rwlock was all wrong, I am copying excerpts
from the https://en.cppreference.com/w/c/atomic/memory_order#Relaxed_ordering
for the convenience of the reader:
Relaxed ordering
Atomic operations tagged memory_order_relaxed are not synchronization
operations; they do not impose an order among concurrent memory
accesses. They only guarantee atomicity and modification order
consistency.
Sequentially-consistent ordering
Atomic operations tagged memory_order_seq_cst not only order memory
the same way as release/acquire ordering (everything that
happened-before a store in one thread becomes a visible side effect in
the thread that did a load), but also establish a single total
modification order of all atomic operations that are so tagged.
Which basically means that we had no or weak synchronization between
threads using the same variables in the rwlock structure. There should
not be a significant performance drop because the critical sections were
already protected by:
while(1) {
if (relaxed_atomic_operation) {
break;
}
LOCK(lock);
if (!relaxed_atomic_operation) {
WAIT(sem, lock);
}
UNLOCK(lock)l
}
I would add one more thing to "Don't do your own crypto, folks.":
- Also don't do your own locking, folks.
As part of this commit, I have also cleaned up the #ifdef spaghetti,
and fixed the isc_atomic API usage.
The ThreadSanitizer found several possible data races in our rwlock
implementation. This commit convert .spins and .write_granted fields
to atomic.
