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
