The BSS to associate with (in either Infrastructure or IBSS join

Association requests are passed to the necessary association functions

association/join/start setup uses settings from the request, not the
current adapter settings (which may not be valid for the requested

libata: always use polling SETXFER
Several people have reported LITE-ON LTR-48246S detection failed

reported for different controllers.
So, now we have pata_via where the controller raises IRQ before it's
ready after SETXFER and a device which does similar thing. This patch
makes libata always execute SETXFER via polling. As this only happens
during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is
also moved from issue hot path to ata_dev_set_xfermode() - the only
place where SETXFER can be issued.
Note that ATA_TFLAG_POLLING applies only to drivers which implement
SFF TF interface and use libata HSM. More advanced controllers ignore
the flag. This doesn't matter for this fix as SFF TF controllers are

[AF_UNIX]: Fix datagram connect race causing an OOPS.
Based upon an excellent bug report and initial patch by
Frederik Deweerdt.
The UNIX datagram connect code blindly dereferences other->sk_socket
via the call down to the security_unix_may_send() function.
Without locking 'other' that pointer can go NULL via unix_release_sock()
which does sock_orphan() which also marks the socket SOCK_DEAD.
So we have to lock both 'sk' and 'other' yet avoid all kinds of
potential deadlocks (connect to self is OK for datagram sockets and it
is possible for two datagram sockets to perform a simultaneous connect
to each other). So what we do is have a "double lock" function similar
to how we handle this situation in other areas of the kernel. We take
the lock of the socket pointer with the smallest address first in
order to avoid ABBA style deadlocks.
Once we have them both locked, we check to see if SOCK_DEAD is set
for 'other' and if so, drop everything and retry the lookup.
