@@ -3,6 +3,24 @@ version 2.86 Thanks to Aichun Li for spotting this ommision, and the initial patch. + Fix bug which caused dnsmasq to lose track of processes forked + to handle TCP DNS connections under heavy load. The code + checked that at least one free process table slot was + available before listening on TCP sockets, but didn't take + into account that more than one TCP connection could + arrive, so that check was not sufficient to ensure that + there would be slots for all new processes. It compounded + this error by silently failing to store the process when + it did run out of slots. Even when this bug is triggered, + all the right things happen, and answers are still returned. + Only under very exceptional circumstances, does the bug + manifest itself: see + https://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2021q2/014976.html + Thanks to Tijs Van Buggenhout for finding the conditions under + which the bug manifests itself, and then working out + exactly what was going on. + + version 2.85 Fix problem with DNS retries in 2.83/2.84. |
