Trusty now has the bug because it does not have the revert of commit
d45d44e:

Trusty only has the one bad commit:
d9ff970 af_unix: Revert 'lock_interruptible' in stream receive code

Wily has the bad commit and the revert to fix it:
26a432a Revert "af_unix: Revert 'lock_interruptible' in stream receive code"
b7a8f5d af_unix: Revert 'lock_interruptible' in stream receive code

Xenial has the bad commit and the revert to fix it:
d45d44e Revert "af_unix: Revert 'lock_interruptible' in stream receive code"
3822b5c af_unix: Revert 'lock_interruptible' in stream receive code


This may be fixed upstream by the following commit:
commit 1b92ee3d03af6643df395300ba7748f19ecdb0c5
Author: Rainer Weikusat 
Date:   Mon Feb 8 18:47:19 2016 +

I built a Xenial test kernel with this commit reverted.  I confirmed
this test kernel resolves the bug on my setup.  It would be great if
others can test this kernel to confirm it resolves the bug.  It can be
downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1540731/Commit3822b5cReverted/

Note, with this test kernel, you need to install both the linux-image
and linux-image-extra .deb packages.

If it is confirmed reverting this commit solves the bug, I will ping
upstream and have this commit reverted or fixed.

This is the commit that introduced this regression in V4.4-rc6:


commit 3822b5c2fc62e3de8a0f33806ff279fb7df92432
Author: Rainer Weikusat 
Date:   Wed Dec 16 20:09:25 2015 +

af_unix: Revert 'lock_interruptible' in stream receive code

With b3ca9b02b00704053a38bfe4c31dbbb9c13595d0, the AF_UNIX SOCK_STREAM
receive code was changed from using mutex_lock(>readlock) to
mutex_lock_interruptible(>readlock) to prevent signals from being
delayed for an indefinite time if a thread sleeping on the mutex
happened to be selected for handling the signal. But this was never a
problem with the stream receive code (as opposed to its datagram
counterpart) as that never went to sleep waiting for new messages with the
mutex held and thus, wouldn't cause secondary readers to block on the
mutex waiting for the sleeping primary reader. As the interruptible
locking makes the code more complicated in exchange for no benefit,
change it back to using mutex_lock.
