Description Manisha Saini 2018-04-02 12:54:37 UTC 
Description of problem:

Ganesha process got crashed while extracting files of the diskfill utility zip folder.


Version-Release number of selected component (if applicable):

# rpm -qa | grep ganesha
nfs-ganesha-2.5.5-3.el7rhgs.x86_64
nfs-ganesha-gluster-2.5.5-3.el7rhgs.x86_64
glusterfs-ganesha-3.12.2-6.el7rhgs.x86_64


How reproducible:
3/3

Steps to Reproduce:
1.Create 4 node ganesha cluster
2.Create 4*3 Distributed-Replicate volume and export the volume via ganesha
3.Mount the volume on windows client
#mount \\10.70.46.37\Ganesha1 N:
4.Mount the same volume on linux client and change permission of nfs share to chmod 777
5.Now copy the diskfill utility zip file on windows NFS mount point
6.Try extracting content of zip folder

Actual results:

Ganesha got crashed (on the node from which the volume was exported) while extracting content of zip folder

=================================
Comment 4 Frank Filz 2018-04-03 04:00:21 UTC 
I think I can recreate this, will work on a fix.
Comment 5 Frank Filz 2018-04-05 05:49:42 UTC 
I strongly suspect this will be fixed by the following series of patches:

I have a set of 4 patches developed while I tried to work this out:

https://review.gerrithub.io/#/c/406501/
https://review.gerrithub.io/#/c/406502/
https://review.gerrithub.io/#/c/406503/
https://review.gerrithub.io/#/c/406504/

https://review.gerrithub.io/#/c/406502/ specifically fixes a refcount problem that results in use after free which most probably causes the issue. The other patches are sort of gravy on top of this.
