git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== This is a batch of updates intended for 3.7. The ath9k, mwifiex, and b43 drivers get the bulk of the commits this time, with a handful of other driver bits thrown-in. It is mostly just minor fixes and cleanups, etc. Also included is a Bluetooth pull, with a lot of refactoring. Gustavo says: "These are the changes I queued for 3.7. There are a many small fixes/improvements by Andre Guedes. A l2cap channel refcounting refactor by Jaganath. Bluetooth sockets now appears in /proc/net, by Masatake Yamato and Sachin Kamat changes ours drivers to use devm_kzalloc()." ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

There are a handle of state machine functions primarily those dealing with processing INIT packets where there is neither a valid endpoint nor a valid assoication from which to derive a struct net.

2012-08-15sctp: Make the port hash table use struct net in it's key.Eric W. Biederman3-11/+16
- Add struct net into the port hash table hash calculation - Add struct net inot the struct sctp_bind_bucket so there is a memory of which network namespace a port is allocated in. No need for a ref count because sctp_bind_bucket only exists when there are sockets in the hash table and sockets can not change their network namspace, and sockets already ref count their network namespace. - Add struct net into the key comparison when we are testing to see if we have found the port hash table entry we are looking for. With these changes lookups in the port hash table becomes safe to use in multiple network namespaces. Signed-off-by: "Eric W.

2012-08-15packet: Diag core and basic socket info dumpingPavel Emelyanov5-0/+139
The diag module can be built independently from the af_packet.ko one, just like it's done in unix sockets. The core dumping message carries the info available at socket creation time, i.e. family, type and protocol (in the same byte order as shown in the proc file). The socket inode number and cookie is reserved for future per-socket info retrieving. The per-protocol filtering is also reserved for future by requiring the sdiag_protocol to be zero.

2012-08-13mac80211: fix unnecessary beacon update after peering status changeMarco Porsch3-34/+33
ieee80211_bss_info_change_notify is called everytime a peer link is established or closed, because the accepting_plinks flag in the meshconf IE *might* have changed. With this patch the corresponding functions return the BSS_CHANGED_BEACON flag when a beacon update is necessary. Also it makes mesh_accept_plinks_update the common place to update the accepting_plinks flag. mesh_accept_plinks_update is called upon plink change and also periodically from ieee80211_mesh_housekeeping. Thus, it also picks up changes of local->num_sta. Signed-off-by: Marco Porsch <marco.porsch@etit.tu-chemnitz.de> Acked-by: Thomas Pedersen <thomas@cozybit.com> Signed-off-by: John W.

The brcmsmac driver requests firmware but doesn't document the dependency. This means that software that analyzes the modules to determine if firmware is needed won't detect it.
