[PATCH 0/2] [SRU][Trusty] Fix for CVE-2017-6345

[Paolo Pisati]

https://people.canonical.com/~ubuntu-security/cve/2017/CVE-2017-6345.html

Patch 01 is a clean cherry-pick and correspond to the upstream fix.
Patch 02 is a partial backport, and contains a prerequisite (sock_efree()).

Instead of importing sock_efree() i could have used sock_edemux() since the two
behave similarly, except when the passed socket is a TCP socket in the
TCP_TIME_WAIT state. But since the TCP states are represented using an enum and
the field sk_state is reused by every protocol, i preferred to avoid introducing
a subtle mistake and use the original sock_efree() function.
