Subject: [PATCH] xtables-monitor: Fix segfault when tracing
|
|
|
|
This is a minimal fix extracted from upstream commit d0446ab11182f
|
|
("xtables: Review nft_init()") which was deemed too untrusive for late
|
|
inclusion into RHEL8.2.
|
|
|
|
(cherry picked from commit e6445667fd0f141ca301aeabeee312545dbf014a)
|
