checkbashisms warns about possible reliance on HOSTNAME environmental
variable which Bash sets to the name of the current host, and some
commands may leverage it:
possible bashism in builtin/tests.sh line 199 ($HOST(TYPE|NAME)):
grep "^\"$HOSTNAME\"$" dig.out.ns1.$n > /dev/null || ret=1
possible bashism in builtin/tests.sh line 221 ($HOST(TYPE|NAME)):
grep "^\"$HOSTNAME\"$" dig.out.ns2.$n > /dev/null || ret=1
possible bashism in builtin/tests.sh line 228 ($HOST(TYPE|NAME)):
grep "^; NSID: .* (\"$HOSTNAME\")$" dig.out.ns2.$n > /dev/null || ret=1
We don't use the variable this way but rename it to HOST_NAME to silence
the tool.

"next_key_event_threshold" is assigned with
"next_key_event_threshold+i", but "i" is empty (never set, nor used
afterwards).
posh, the Policy-compliant Ordinary SHell, failed on this assignment

There were a number of places where the zone table should have been
locked, but wasn't, when dns_zt_apply was called.
Added a isc_rwlocktype_t type parameter to dns_zt_apply and adjusted
all calls to using it. Removed locks in callers.

Firefox 90+ apparently sends more than 10 headers, so we need to bump
the number to some higher number. Bump it to 100 just to be on a save
side, this is for internal use only anyway.

If 'set -x' is in effect file.prev gets populated with debugging output.
To prevent this open descriptor 3 and redirect stderr from the awk
command to descriptor 3. Debugging output will stay directed to stderr.

Using the -x option for cherry pick makes it easy to link commits across
branches and it is recommended to use for all backport commits (with
exceptions -- thus a warning level rather than failure).

To avoid accidentally merging unfinished work, detect prohibited
keywords at the start of the subject line. If the first word is any of
the following, fail the check:
WIP, wip, DROP, drop, TODO, todo
The only slightly controversial is the lowercase "drop" which might have
a legitimate use - seems like four commits in the history used it as a
start of a sentence. However, since people commonly use "drop" to
indicate a commit should be dropped before merging, let's prohibit it as
well. In case of false-positive, "Drop" with a capitalized first letter
can always be used.

Since the LGTM label was deprecated in favor of using the Approve button
in gitlab, adjust the detection in danger bot.
Unfortunately, danger-python seems no longer maintained since 2020 and
MR approvals aren't available in its Python API (even though they're
supported in its Ruby/JS APIs). Going forward, let's use the more
comprehensive python-gitlab API.
It still makes sense to utilize the danger-python, since it handles the
integration with gitlab which doesn't need to be reimplemented as long
as it works - same with the other checks.

From now on all per-version notes link to the global list

The zone_refreshkeys() could run before the zone_shutdown(), but after
the last .erefs has been "detached" causing assertion failure when doing
dns_zone_attach(). Remove the use of .erefs (dns_zone_attach/detach)
and replace it with using the .irefs and additional checks whether the
zone is exiting in the callbacks.

If after a reconfig a zone is not reusable because inline-signing
was turned on/off, trigger a full resign. This is necessary because
otherwise the zone maintenance may decide to only apply the changes
in the journal, leaving the zone in an inconsistent DNSSEC state.
(cherry picked from commit 4d143f2cc4)
There was an exception for dnssec-policy that allowed DNSSEC in the
unsigned version of the zone. This however causes a crash if the
zone switches from dynamic to inline-signing in the case of NSEC3,
because we are now trying to add an NSEC3 record to a non-NSEC3 node.
This is because BIND expects none of the records in the unsigned
version of the zone to be NSEC3.
Remove the exception for dnssec-policy when copying non DNSSEC
records, but do allow for DNSKEY as this may be a published DNSKEY
from a different provider.
(cherry picked from commit 332b98ae49)
The changes in the code have the side effect that the CDNSKEY and CDS
records in the secure version of the zone are not reusable and thus
are thrashed from the zone. Remove the apex checks for this use case.
We only care about that the zone is not immediately goes bogus, but
a user really should use the built-in "insecure" policy when unsigning
a zone.
(cherry picked from commit bc703a12e7)
Similar to an attempt to add NSEC through dynamic update, add a test
case that tries to add NSEC3 through zone transfer.
(cherry picked from commit ef1cb9935c)
Add one more case that tests reconfiguring a zone to turn off
inline-signing. It should still be a valid DNSSEC zone and the NSEC3
parameters should not change.
Add another test to ensure that you cannot update the zone with a
NSEC3 record.
(cherry picked from commit 4cd8e8e9c3)
We no longer accept copying DNSSEC records from the raw zone to
the secure zone, so update the kasp system test that relies on this
accordingly.
Also add more debugging and store the dnssec-verify results in a file.
(cherry picked from commit 57ea9e08c6)
Add a kasp system test that reconfigures a dnssec-policy zone from
maintaining DNSSEC records directly to the zone to using inline-signing.
Add a similar test case to the nsec3 system test, testing the same
thing but now with NSEC3 in use.
(cherry picked from commit 9018fbb205)
When named starts it creates an empty KEYDATA record in the managed-keys
zone as a placeholder, then schedules a key refresh. If key refresh
fails for some reason (e.g. connectivity problems), named will load the
placeholder key into secroots as a trusted key during the next startup,
which will break the chain of trust, and named will never recover from
that state until managed-keys.bind and managed-keys.bind.jnl files are
manually deleted before (re)starting named again.
Before calling load_secroots(), check that we are not dealing with a
placeholder.
(cherry picked from commit 354ae2d7e3)
Add a dnssec test to make sure that named can correctly process a
managed-keys zone with a placeholder KEYDATA record.
(cherry picked from commit 8c48eabbc1)
Because dns_resolver_createfetch() locks the view, it was necessary
to unlock the zone in zone_refreshkeys() before calling it in order
to maintain the lock order, and relock afterward. this permitted a race
with dns_zone_synckeyzone().
This commit moves the call to dns_resolver_createfetch() into a separate
function which is called asynchronously after the zone has been
unlocked.
The keyfetch object now attaches to the zone to ensure that
it won't be shut down before the asynchronous call completes.
This necessitated refactoring dns_zone_detach() so it always runs
unlocked. For managed zones it schedules zone_shutdown() to
run asynchronously; for unmanaged zones there is no task.
The NetBSD system allocator is in fact based on the jemalloc, but it
doesn't export the extended interface, so we can't use that. Remove
the jemalloc enforcement for the NetBSD.
