Subject: [PATCH] Clear qctx->zversion
|
||
|
|
|
||
|
|
Clear qctx->zversion when clearing qctx->zrdataset et al in
|
||
|
|
lib/ns/query.c:qctx_freedata. The uncleared pointer could lead to
|
||
|
|
an assertion failure if zone data needed to be re-saved which could
|
||
|
|
happen with stale data support enabled.
|
||
|
|
|
||
|
|
(cherry picked from commit 179fb3532ab8d4898ab070b2db54c0ce872ef709)
