Bug Fixes

Tweak and reword release notes

- Previously, zone maintenance DNS queries retried forever if the
destination server was unreachable. These queries included outgoing
Ensure that dns_request_createvia() has a retry limit There are a couple of problems with dns_request_createvia(): a UDP retry count of zero means unlimited retries (it should mean no retries), and the overall request timeout is not enforced. The combination of these bugs means that requests can be retried forever. This change alters calls to dns_request_createvia() to avoid the infinite retry bug by providing an explicit retry count. Previously, the calls specified infinite retries and relied on the limit implied by the overall request timeout and the UDP timeout (which did not work because the overall timeout is not enforced). The `udpretries` argument is also changed to be the number of retries; previously, zero was interpreted as infinity because of an underflow to UINT_MAX, which appeared to be a mistake. And `mdig` is updated to match the change in retry accounting. The bug could be triggered by zone maintenance queries, including NOTIFY messages, DS parental checks, refresh SOA queries and stub zone nameserver lookups. It could also occur with `nsupdate -r 0`. (But `mdig` had its own code to avoid the bug.) (cherry picked from commit 71ce8b0a51bc028ed46541d274965e7e4b5fc832)

zone NS queries. For example, if a zone had any nameservers with IPv6
addresses and a secondary server without IPv6 connectivity, that
server would keep trying to send a growing amount of NOTIFY traffic
over IPv6. This futile traffic was not logged. This excessive retry
behavior has been fixed. :gl:`#3242`

- Handling of TCP write timeouts has been improved to track the timeout
for each TCP write separately, leading to a faster connection teardown
in case the other party is not reading the data. :gl:`#3200`
