Subject[3.14.y][3.16.y-ckt][3.18.y][3.19.y][PATCH 0/1] n_tty: Fix read buffer overwrite when no newline
Date
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.

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.


Sincerely,

Joseph Salisbury
