The previous value of 30 minutes used to cache the ADB names and entries
was quite long. Change the value to 60 seconds for faster recovery
after cached intermittent failure of the remote nameservers.
The algorithm from the previous commit[1] is now used to calculate all
the expiration values through the code (ncache results, cname/dname
targets).
1. ISC_MIN(cur, ISC_MAX(now + ADB_ENTRY_WINDOW, now + rdataset->ttl))
Correct the logic to set the expiration period of expire_{v4,v6} as
follows:
1. If the trust is ultimate (local entry), immediately set the entry as
expired, so the changes to the local zones have immediate effect.
3. If the expiration is already set and smaller than the new value, then
leave the expiration value as it is.
2. Otherwise pick larger of `now + ADB_ENTRY_WINDOW` and `now + TTL` as
the new expiration value.
When ADB entry was created it was set to never expire. If we never
called any of the functions that adjust the expiration, it could linger
in the ADB forever.
Set the expiration (.expires) to now + ADB_ENTRY_WINDOW when creating
the new ADB entry to ensure the ADB entry will always expire.
In the past, our CI infrastructure was more sensitive to the number of
CI jobs running on it. We tried to limit long-running jobs in merge
request-triggered pipelines, as there are many of them, and spawned them
only in daily scheduled ones. Moving most of the CI infrastructure to
AWS has made it way better to run jobs in parallel, and the existence of
short respdiff jobs has lost its original merit. It can also be harmful
as some problems are detected only by the longer respdiff variant when a
faulty merge request has already been merged. We should run all long
respdiff tests in merge request-triggered pipelines.
Also, move the former respdiff-long job (now just "respdiff") to AWS as
old instance memory constraints (see
f09cf69594) are no longer an issue.
We now have ctx.kskflag, ctx.zskflag, and ctx.revflag, but zskflag is
not quite like the other two, as it doesn't have a special bit in the
DNS packet, and is used as a boolean.
This patch changes so that we use booleans for all three, and
construct the flags based on which ones are set.

Add test cases for the 'request' command. Reuse the earlier
pregenerated ZSKs. We also need to set up some KSK files, that can
be done with 'dnssec-keygen -k <policy> -fK' now.
The 'check_keys()' function is adjusted such that the expected active
time of the successor key is set to the inactive time of the
predecessor. Some additional information is saved to make 'request'
testing easier.
Add code that can create a Key Signing Request (KSR) given a DNSSEC
policy, a set of keys and an interval.
Multiple keys that match the bundle and kasp parameters are sorted by
keytag, mainly for testing purposes.
Create some helper functions for code that is going to be reused by the
other commands (request, sign), such as setting and checking the context
parameters, and retrieving the dnssec-policy/kasp.
The 'dnssec-keygen' tool now allows the options '-k <dnssec-policy>'
and '-f <flags>' together to create keys from a DNSSEC policy that only
match the given role. Allow setting '-fZ' to only create ZSKs, while
'-fK' will only create KSKs.
Add a system test for testing dnssec-ksr, initally for the keygen
command. This should be able to create or select key files given a
DNSSEC policy and a time window.
Introduce a new DNSSEC tool, dnssec-ksr, for creating signed key
response (SKR) files, given one or more key signing requests (KSRs).
For now it is just a dummy tool, but the future purpose of this utility
is to pregenerate ZSKs and signed RRsets for DNSKEY, CDNSKEY, and CDS
for a given period that a KSK is to be offline.
Previously, only a single controlconf message would be processed from a
single TCP read even if the TCP read buffer contained multiple messages.
Refactor the isccc_ccmsg unit to store the extra buffer in the internal
buffer and use the already read data first before reading from the
network again.

The xmlGetGlobalState allocates per-thread memory that is not properly
cleaned up when the libxml2 is used from offloaded threads. Add the
function the the LeakSanitizer suppression list.
