multipath-tools: check for initialized checker before
|
|
|
|
This fixes a regression added with:
|
|
015f87b16a7797a17afd514aec46e65c2a1a2f73
|
|
|
|
We can hit a race where when pathinfo is setting up a path, the path
|
|
could have gone down already. In the DI_CHECKER chunk we then do not
|
|
run
|
|
get_state and attach a checker. Later when check_path is run
|
|
path_offline could still return PATH_DOWN or PATH_REMOVED and
|
|
get_state is again not run so we do not get to attach a checker. I
|
|
was then running repair_path since the state was PATH_DOWN, and we
|
|
then
|
|
hit a segfault.
|
|
|
|
This has us test if a checker is selected before running repair.
