In the Linux kernel, the following vulnerability has been resolved:

ocfs2: remove entry once instead of null-ptr-dereference in ocfs2xaremove()

Syzkaller is able to provoke null-ptr-dereference in ocfs2xaremove():

[ 57.319872] (a.out,1161,7):ocfs2xaremove:2028 ERROR: status = -12 [ 57.320420] (a.out,1161,7):ocfs2xacleanupvaluetruncate:1999 ERROR: Partial truncate while removing xattr overlay.upper.

Reproducer uses faultinject facility to fail ocfs2xaremove() -> ocfs2xavaluetruncate() with -ENOMEM.

In this case the comment mentions that we can return 0 if ocfs2xacleanupvaluetruncate() is going to wipe the entry anyway. But the following 'rc' check is wrong and execution flow do 'ocfs2xaremoveentry(loc);' twice: 1st: in ocfs2xacleanupvaluetruncate(); 2nd: returning back to ocfs2xaremove() instead of going to 'out'.

Fix this by skipping the 2nd removal of the same entry and making syzkaller repro happy.
