Nick O'Connor (nick-oconnor) wrote : SEGFAULTs in v4.3

[ Impact ]

 * Users experience SEGFAULTs when Ganesha fails to communicate with Gluster, causing the NFS share to disappear.

 * The patch refactors how free_space() is called to avoid the null pointer deference.

[ Test Plan ]

 * The triggers for the issue are difficult to replicate and have to do with the timing of Ganesha communicating with Gluster. I have compiled the patch against version 4.3-8ubuntu1 of nfs-ganesha and it resolved the issue on my system.

[ Where problems could occur ]

 * Possible memory leaks, however this change has been part of nfs-ganesha since v5. The latest version of nfs-ganesha is 5.7. I don't know of other related issues.
