** Description changed:
== Regression details ==
Discovered in version: 3.2.0
Last known good version: 3.0.0
+ This issue was introduced in commit
+ fec11dd9a0109fe52fd631e5c510778d6cbff6cc.
+
Mounting a cifs path which is below a symlink on the server causes oops.
Consider the following tree:
- /srv/symtest
- /srv/symtest/dir
- /srv/symtest/dir/subdir
- /srv/symtest/link -> dir
+ /srv/symtest
+ /srv/symtest/dir
+ /srv/symtest/dir/subdir
+ /srv/symtest/link -> dir
this works:
# mount.cifs //smbsrv/symtest/dir/subdir/ /mnt/
this causes oops:
# mount.cifs //smbsrv/symtest/link/subdir/ /mnt/
A example of the oops may be found in
