Hello, Please consider including upstream commit fb5ef9e7da39968fec6d6f37f20a23d23740c75e in the next v3.14.y, 3.16.y-ckt, 3.18.y, and 3.19.y stable releases. It was included upstream 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. commit fb5ef9e7da39968fec6d6f37f20a23d23740c75e Author: Peter Hurley <peter@xxxxxxxxxxxxxxxxxx> Date: Fri Jan 16 15:05:39 2015 -0500 n_tty: Fix read buffer overwrite when no newline This commit does not apply cleanly to the kernel versions mentined, so I performed a backport, which is in email 1/1. The 3.12.y and 3.13.y-ckt upstrem kernels can't use the cherry pick of fb5ef9e7 becuase smp_load_acquire was not introduced until 3.14-rc1. I'll look into alternative way that this bug could be fixed in 3.12.y and 3.13.y-ckt.
