Title
tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().
Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().
Anderson Nascimento reported a use-after-free splat in tcp_twsk_unique()
with nice analysis.
Since commit ec94c2696f0b ("tcp/dccp: avoid one atomic operation for
timewait hashdance"), inet_twsk_hashdance() sets TIME-WAIT socket's
sk_refcnt after putting it into ehash and releasing the bucket lock.
Thus, there is a small race window where other threads could try to
reuse the port during connect() and call sock_hold() in tcp_twsk_unique()
for the TIME-WAIT socket with zero refcnt.
If that happens, the refcnt taken by tcp_twsk_unique() is overwritten
and sock_put() will cause underflow, triggering a real use-after-free
somewhere else.
To avoid the use-after-free, we need to use refcount_inc_not_zero() in
tcp_twsk_unique() and give up on reusing the port if it returns false.
[0]:
refcount_t: addition on 0; use-after-free.

Title
gfs2: Fix potential glock use-after-free on unmount
Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix potential glock use-after-free on unmount
When a DLM lockspace is released and there ares still locks in that
lockspace, DLM will unlock those locks automatically. Commit
fb6791d100d1b started exploiting this behavior to speed up filesystem
unmount: gfs2 would simply free glocks it didn't want to unlock and then
release the lockspace. This didn't take the bast callbacks for
asynchronous lock contention notifications into account, which remain
active until until a lock is unlocked or its lockspace is released.
To prevent those callbacks from accessing deallocated objects, put the
glocks that should not be unlocked on the sd_dead_glocks list, release
the lockspace, and only then free those glocks.
As an additional measure, ignore unexpected ast and bast callbacks if
the receiving glock is dead.
