This patch set implements a bugfix for kernel.org bugzilla #12323, allowing
MSG_PEEK to return all queued data on the unix domain socket, not just the
data contained in a single SKB.
This is the v3 version of this patch, which includes a suggested modification
by Eric Dumazet to convert the unix_sk() conversion macro to a static inline
function. These patches are independent and can be applied separately.
This set was tested over a 24-hour period, utilizing a loop continually
executing the bugzilla issue attached python code. It was instrumented with
a pr_err_once() ([ 13.798683] unix: went there at least one time).
v2->v3:
- Added Eric Dumazet's suggestion for #define to static inline
- Fixed an issue calling unix_state_lock() with an invalid argument
v3->v4:
- Eliminated an XXX comment
- Changed from goto unlock to explicit unix_state_unlock() and break
