[Joseph Salisbury <joseph.salisbury@canonical.com>]

Hello,

Please consider including mainline commit fb5ef9e7da39968fec6d6f37f20a23d23740c75e 
in the next v3.12.y, v3.13.y-ckt, v3.14.y, 3.16.y-ckt, 3.18.y, and 3.19.y stable releases.  
It was included mainline as of v4.0-rc1.  It has been tested and confirmed to resolve
http://bugs.launchpad.net/bugs/1381005 .  This bug was introduced in v3.12-rc1 when 
commit 24a89d1 was applied.  This commit is not needed in stable kernels prior to 
v3.12.y.

    n_tty: Fix read buffer overwrite when no newline


This commit does not apply cleanly to the kernels versions mentined, so I performed 
a backport, which is in email 1/1.

The 3.12.y and 3.13.y-ckt stable releases first need a cherry pick of commit
5c32d12378313e0096ea0d450462aa638a90fb6e.  This is because in commit 5c32d123
n_tty_receive_buf and n_tty_receive_buf2 were merged into n_tty_receive_buf_common,
which is where the backport makes the needed changes. 


Sincerely,

Joseph Salisbury
