-Subject: [PATCH] Fix infinite retries in strict-order mode.
-
- If all configured dns servers return refused in
- response to a query; dnsmasq will end up in an infinite loop
- retransmitting the dns query resulting into high CPU load.
- Problem is caused by the dns refuse retransmission logic which does
- not check for the end of a dns server list iteration in strict mode.
- Having one configured dns server returning a refused reply easily
- triggers this problem in strict order mode. This was introduced in
- 9396752c115b3ab733fa476b30da73237e12e7ba
-
- Thanks to Hans Dedecker <dedeckeh@gmail.com> for spotting this
- and the initial patch.
