marker: Fix inode value in loc, in setxattr fop
On recieving a rename fop, marker_rename() stores the, oldloc and newloc in its 'local' struct, once the rename is done, the xtime marker(last updated time) is set on the file, but sending a setxattr fop. When upcall receives the setxattr fop, the loc->inode is NULL and it crashes. The loc->inode can be NULL only in one valid case, i.e. in rename case where the inode of new loc can be NULL. Hence, marker should have filled the inode of the new_loc before issuing a setxattr. marker_rename_cbk was already fixed in a previous commit. Fixing marker_rename_done to send valid inode in this commit. Also in upcall check for NULL inode so that there is no crash. >Reviewed-on: https://review.gluster.org/16633 >Reviewed-by: Kotresh HR <khiremat@redhat.com> >Smoke: Gluster Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: soumya k <skoduri@redhat.com> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >Reviewed-by: Raghavendra G <rgowdapp@redhat.com> >(cherry picked from commit 73defab8be16b73241225bb1c2588a61e3e425d5) Change-Id: I3ed2a05118fed3367dfe3251ce4477310cb480d0 BUG: 1424937 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: https://review.gluster.org/16684 Tested-by: Atin Mukherjee <amukherj@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
