Subject: [PATCH 265/271] Glusterfsd: brick crash during get-state
|
|
|
|
back-port of: https://review.gluster.org/#/c/19977/
|
|
|
|
The xprt's dereferencing wasn't checked before using it for the
|
|
strcmp, which caused the segfault and crashed the brick process.
|
|
|
|
fix: Check every deferenced variable before using it.
