The missing l3num initialization is enough for this, this patch changes it to use AF_UNSPEC to make it more explicit though.

We now have a report of a system fitted with an EEPROM containing all zeros where we expect the MAC address to be, and we currently handle this as an error condition. Turns out, on this system the BIOS writes a valid MAC address to the NIC's MAC Station Address register, but we never try to read it because we return an error when we find the all- zeros address in EEPROM. This patch relaxes the error check and continues looking for a MAC address even if it finds an illegal one in EEPROM.

This routine is used by both SOCK_DGRAM and SOCK_SEQPACKET sockets. The poll-implementation for these socket types is datagram_poll from core/datagram.c. A socket is deemed to be writeable by this routine when the memory presently consumed by datagrams owned by it is less than the configured socket send buffer size. This is always wrong for connected PF_UNIX non-stream sockets when the abovementioned receive queue is currently considered to be full. 'poll' will then return, indicating that the socket is writeable, but a subsequent write result in EAGAIN, effectively causing an (usual) application to 'poll for writeability by repeated send request with O_NONBLOCK set' until it has consumed its time quantum. The change below uses a suitably modified variant of the datagram_poll routines for both type of PF_UNIX sockets, which tests if the recv-queue of the peer a socket is connected to is presently considered to be 'full' as part of the 'is this socket writeable'-checking code. The socket being polled is additionally put onto the peer_wait wait queue associated with its peer, because the unix_dgram_sendmsg routine does a wake up on this queue after a datagram was received and the 'other wakeup call' is done implicitly as part of skb destruction, meaning, a process blocked in poll because of a full peer receive queue could otherwise sleep forever if no datagram owned by its socket was already sitting on this queue. Among this change is a small (inline) helper routine named 'unix_recvq_full', which consolidates the actual testing code (in three different places) into a single location.

The problem is that the mac80211 stack not only needs to be able to muck with the link-level headers, it also might need to mangle all of the packet data if doing sw wireless encryption. This fixes kernel bugzilla #10903. Thanks to Didier Raboud (for the bugzilla report), Andrew Prince (for bisecting), Johannes Berg (for bringing this bisection analysis to my attention), and Ilpo (for trying to analyze this purely from the TCP side). In 2.6.27 we can take another stab at this, by using something like skb_cow_data() when the TX path of mac80211 ends up with a non-NULL tx->key. The ESP protocol code in the IPSEC stack can be used as a model for implementation. Signed-off-by: David S.
