BUFSIZ (512 bytes on Windows) may not be enough to fit the status of a
DNSSEC policy and three DNSSEC keys.
Set the size of the relevant buffer to a hardcoded value of 4096 bytes,
which should be enough for most scenarios.
(cherry picked from commit 9347e7db7e)
While the creation and publication times of the various keys
in this policy are nearly at the same time there is a chance that
one key is created a second later than the other.
The `set_keytimes_algorithm_policy` mistakenly set the keytimes
for KEY3 based of the "published" time from KEY2.

Commit b580eb2fb3 inadvertently caused the
man pages for symlinked BIND tools (named-compilezone, tsig-keygen) to
no longer be installed by "make install". Fix by restoring the commands
which ensure that.
Commit b580eb2fb3 inadvertently caused
dnstap-related man pages to be installed unconditionally. Ensure they
are only installed for dnstap-enabled builds.
When we're coming back from recursion fetch_callback does not accept
DNS_R_NXDOMAIN as an rcode - query_gotanswer calls query_nxdomain in
which an assertion fails on qctx->is_zone. Yet, under some
circumstances, qname minimization will return an DNS_R_NXDOMAIN - when
root zone mirror is not yet loaded. The fix changes the DNS_R_NXDOMAIN
answer to DNS_R_SERVFAIL.
This test ensures that named will correctly shutdown
when receiving multiple control connections after processing
of either "rncd stop" or "kill -SIGTERM" commands.
Before the fix, named was crashing due to a race condition happening
between two threads, one running shutdown logic in named/server.c
and other handling control logic in controlconf.c.
This test tries to reproduce the above scenario by issuing multiple
queries to a target named instance, issuing either rndc stop or kill
-SIGTERM command to the same named instance, then starting multiple rndc
status connections to ensure it is not crashing anymore.
(cherry picked from commit 042e509753)
Due to lack of synchronization, whenever named was being requested to
stop using rndc, controlconf.c module could be trying to access an already
released pointer through named_g_server->interfacemgr in a separate
thread.
The race could only be triggered if named was being shutdown and more
rndc connections were ocurring at the same time.
This fix correctly checks if the server is shutting down before opening
a new rndc connection.

When a library is examined, an object file within it can be left out
of the link if it does not provide symbols that the symbol table
needs. Introducing `isc_stdtime_tostring` caused a build failure for
`update_test` because it now requires `libisc.a(stdtime.o)` and that
also exports the `isc_stdtime_get` symbol, meaning we have a
multiple definition error.
Add a local version of `isc_stdtime_tostring`, so that the linker
will not search for it in available object files.
Implement the 'rndc dnssec -status' command that will output
some information about the key states, such as which policy is
used for the zone, what keys are in use, and when rollover is
scheduled.
Add loose testing in the kasp system test, the actual times are
already tested via key file inspection.
(cherry picked from commit 19ce9ec1d4)
Add the code and documentation required to provide DNSSEC signing
status through rndc. This does not yet show any useful information,
just provide the command that will output some dummy string.
(cherry picked from commit e1ba1bea7c)
I'd like to use the same functionality (pretty print the datetime
of keytime metadata) in the 'rndc dnssec -status' command. So it is
better that this logic is done in a separate function.
Since the stdtime.c code have differernt files for unix and win32,
I think the "#ifdef WIN32" define can be dropped.

the blackhole ACL was accidentally disabled with respect to client
queries during the netmgr conversion.
in order to make this work for TCP, it was necessary to add a return
code to the accept callback functions passed to isc_nm_listentcp() and
isc_nm_listentcpdns().

Make yaml.load_all() use yaml.SafeLoader to address a warning currently
emitted when bin/tests/system/dnstap/ydump.py is run:
ydump.py:28: YAMLLoadWarning: calling yaml.load_all() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
for l in yaml.load_all(f.stdout):
The `rndc` argument was always overridden by the static configuration,
because the logic for handling the number of dnstap files to retain
was both backwards and a bit redundant.
