[ Analysis ]

We believe that we have found a concurrency bug in the fs/jfs module that results in a null pointer dereference. There is a closely related issue which has been fixed:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d6c1b3599b2feb5c7291f5ac3a36e5fa7cedb234

... but, unfortunately, the accepted patch appears to still be susceptible to a null pointer dereference under some interleavings.

To trigger the bug, we think that JFSSBI(ipbmap->isb)->bmap is set to NULL in dbFreeBits and then dereferenced in jfsioctrim. This bug manifests quite rarely under normal circumstances, but is triggereable from a syz-program.
