The caif_hsi.c, on the other hand, was not. It's a conflict between 1c385f1fdf6f9c66d982802cd74349c040980b50 ("caif-hsi: Replace platform device with ops structure.") in the net-next tree and commit 39abbaef19cd0a30be93794aa4773c779c3eb1f3 ("caif-hsi: Postpone init of HIS until open()") in the net tree. I did my best with that one and will ask Sjur to check it out. Signed-off-by: David S. Miller <davem@davemloft.net>

Avinash Patil gives us a fix for for a memory leak in mwifiex. Dan Rosenberg offers an NFC NCI fix to enforce some message length limits to prevent buffer overflows. Eliad Peller provides a mac80211 fix to prevent some frames from being built with an invalid BSSID. Eric Dumazet sends an NFC fix to prevent a BUG caused by a NULL pointer dereference. Felix Fietkau has an ath9k fix for a regression causing LEAP-authenticated connection failures. Johannes Berg provides an iwlwifi fix that eliminates some log SPAM after an authentication/association timeout. He also provides a mac80211 fix to prevent incorrectly addressing certain action frames (and in so doing, to comply with the 802.11 specs). Larry Finger provides a few USB IDs for the rtl8192cu driver -- should be harmless. Panayiotis Karabassis provices a one-liner to fix kernel bug 42903 (a system freeze). Randy Dunlap provides a one-line Kconfig change to prevent build failures with some configurations. Stone Piao provides an mwifiex sequence numbering fix and a fix to prevent mwifiex from attempting to include eapol frames in an aggregation frame. Finally, Tom Hughes provides an ath9k fix for a NULL pointer dereference. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | | * mac80211: correct behaviour on unrecognised action framesJohannes Berg2012-06-271-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When receiving an "individually addressed" action frame, the receiver is required to return it to the sender. mac80211 gets this wrong as it also returns group addressed (mcast) frames to the sender. Fix this and update the reference to the new 802.11 standards version since things were shuffled around significantly.

Fix it by clearing ifmgd->bssid only after building all the needed frames. After this change, we no longer need to save the bssid (before clearing it), so remove the local array.

This is a bug since those ops aren't defined to be ceph_con_get/put. This breaks refcounting on the ceph_osd structs that contain the ceph_connections, and could lead to all manner of strangeness. The purpose of the ->get and ->put methods in a ceph connection are to allow the connection to indicate it has a reference to something external to the messaging system, *not* to indicate something external has a reference to the connection.

In this case the node would add two events to the events list (that is going to be sent appended to the next OGM). A DEL one and an ADD one. Obviously they will only increase the overhead (either in the air and on the receiver side) and eventually trigger wrong states/events without producing any real effect. For this reason we can safely delete any ADD event with its related DEL one. Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: Sven Eckelmann <sven@narfation.org>

Usually this is the original packet source address, but if we are responding to a multicast or broadcast packet we have to use something different. Specifically we must use the source address we would use if we were to send a packet to the unicast source of the original packet. The routing cache precomputes this value, but we want to remove that precomputation because it creates a hard dependency on the expensive rpfilter source address validation which we'd like to make cheaper. There are only three places where this matters: 1) ICMP replies. 2) pktinfo CMSG 3) IP options Now there will be no real users of rt->rt_spec_dst and we can simply remove it altogether.
