Subject: fix: dev: Check if logconfig is NULL before using it in isc_log_doit()
X-Git-Tag: v9.21.1~45
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=ebd669a830307385d4aeefde2246cedbefa1fc33;p=thirdparty%2Fbind9.git

fix: dev: Check if logconfig is NULL before using it in isc_log_doit()

Check if 'lctx->logconfig' is NULL before using it in isc_log_doit(),
because it's possible that isc_log_destroy() was already called, e.g.
when a 'call_rcu' function wants to log a message during shutdown.

Closes #4842

Merge branch '4842-shutdown-crash-in-isc_log_doit' into 'main'

Closes #4842
