April backports
In April we had a rule for the v9_16 branch that only security and QA-approved backports are allowed. This attempted to ensure stability of the 9.16 release, but broke the general rule that backports happen in the same month. The following merge request were not backported in April (but were tagged as such) and should be backported in the future (i.e. in May).
- !4862 (merged): "Change default stale-answer-client-timeout to off" (May may be too early)
- !4834 (merged): "Resolve "Make calling generic rdata methods consistent""
- !4628 (merged): "Improve reliability of the netmgr unit tests"
- !4792 (merged): "Load full certificate chain from a certificate chain file"
- !4851 (merged): "TLS transport code refactoring and unit tests"
- !4840 (merged): "Do not require config.h to use isc/util.h"
- !4834 (merged): "Resolve "Make calling generic rdata methods consistent""
- !4824 (merged): "Call isc__nm_tlsdns_failed_read on tls_error to cleanup the socket"
- !4820 (merged): "Fix dangling uvreq when data is sent from tlsdns_cycle()"
- !4809 (merged): "Fix memory accounting bug in TLSDNS"
- !4803 (merged): "Fix a XoT crash"
MRs should be checked off when backported or crossed out and labels fixed in the MR if not meant to be backported.
