[PATCH v2 1/2] multipathd: fix null pointer dereference in uev_update_path

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The Auto-resize code added a check that deferences pp->mpp without
checking that it's non-NULL. Fix it.

Fixes: 981b83ad1 ("multipathd: Add auto_resize config option")
