Description

In the Linux kernel, the following vulnerability has been resolved:EOL][EOL]gfs2: No more self recovery[EOL][EOL]When a node withdraws and it turns out that it is the only node that has[EOL]the filesystem mounted, gfs2 currently tries to replay the local journal[EOL]to bring the filesystem back into a consistent state.  Not only is that[EOL]a very bad idea, it has also never worked because gfs2_recover_func()[EOL]will refuse to do anything during a withdraw.[EOL][EOL]However, before even getting to this point, gfs2_recover_func()[EOL]dereferences sdp->sd_jdesc->jd_inode.  This was a use-after-free before[EOL]commit 04133b607a78 ("gfs2: Prevent double iput for journal on error")[EOL]and is a NULL pointer dereference since then.[EOL][EOL]Simply get rid of self recovery to fix that.
