>Description:
Kernel panics immediately when calling the SIOCAUTHW ioctl for /dev/ipauth device. As far as I managed to understand in happens because the fr_authwait() functions tries to release the ipf_global lock which is not actually held.

The problem has been introduced by the post-4.1.28 fixes.

>How-To-Repeat:
Open the /dev/ipauth device and call SIOCAUTHW ioctl.
