Subject: [9.20] fix: usr: Prevent a crash when using both dns64 and filter-aaaa
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ddcacbc5a84f43daa1cc80a2565b7336a1290744;p=thirdparty%2Fbind9.git

[9.20] fix: usr: Prevent a crash when using both dns64 and filter-aaaa

An assertion failure could be triggered if both `dns64` and the `filter-aaaa` plugin were in use simultaneously. This happened if the plugin triggered a second recursion process, which then attempted to store DNS64 state information in a pointer that had already been set by the original recursion process. This has been fixed.

Closes #5854
