Subject: CVE request: kernel: bluetooth: l2cap and rfcomm: fix 1 byte infoleak
 to userspace

>From Marek Kroemeke and Filip Palian, structures "l2cap_conninfo" and
"rfcomm_conninfo" have one padding byte each. This byte in "cinfo" is
copied to userspace uninitialized.

l2cap: since 99f4808d (v2.6.39-rc1), also in l2cap.c prior to that
history:e9df2323 (v2.5.14)
rfcomm: since history:9363d05d (v2.6.11-rc2)
