This patch includes many places, that only required replacing the ctl_table-s with appropriate ctl_paths and call register_sysctl_paths(). Nothing special was done with them. Signed-off-by:

- The DNAT (Destination NAT) is not implemented in IPV4. - This patch remove the code which checks these flags in net/ipv4/arp.c and net/ipv4/route.c. The RTCF_NAT and RTCF_NAT should stay in the header (linux/in_route.h) because they are used in DECnet. Signed-off-by:

The file net/tipc/port.c takes a lock using the function tipc_port_lock and then releases the lock sometimes using tipc_port_unlock and sometimes using spin_unlock_bh(p_ptr->publ.lock). tipc_port_unlock simply does the spin_unlock_bh, but it seems cleaner to use it everywhere. The problem was fixed using the following semantic patch. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct port *p_ptr; @@ p_ptr = tipc_port_lock(...) ... ( p_ptr = tipc_port_lock(...); | ?- spin_unlock_bh(p_ptr->publ.lock); + tipc_port_unlock(p_ptr); ) // </smpl> Signed-off-by:

Some devices have a seperate LED which indicates if the radio is enabled or not. This adds a LED trigger to mac80211 where drivers can hook into when they are interested in radio status changes. v2: Check hw.conf.radio_enabled when calling start(). Signed-off-by:

I would argue that mac80211 should handle fixed rates outside the rate control code, which would also allow them to take effect immediately instead of during the rate control callback, but this is pretty close to correct. Signed-Off-By:

This patch changes mac80211's Kconfig/Makefile to: * select between the PID and the SIMPLE rate control algorithm as default * always allow tri-state for the rate control algorithms, building those that are selected 'y' into the mac80211 module (if that is a module, otherwise all into the kernel) * force the default rate control algorithm to be built into mac80211 It also makes both rate control algorithms proper modules again with MODULE_LICENSE etc. Only if EMBEDDED is the user allowed to select "NONE" as default which will cause no algorithm to be selected, this will work only when the driver brings one itself (e.g. iwlwifi drivers).

This patch handles the reordering of the Rx A-MPDU. This issue occurs when the sequence of the internal MPDUs is not in the right order. such a case can be encountered for example when some MPDUs from previous aggregations were recieved, while others failed, so current A-MPDU will contain a mix of re-transmited MPDUs and new ones.

This patch makes a separation between Rx frame pre-handling which stays in __ieee80211_rx and Rx frame handlers, moving to __ieee80211_rx_handle_packet. Although this separation has no affect in regular mode of operation, this kind of mechanism will be used in A-MPDU frames reordering as it allows accumulation of frames during pre-handling, dispatching them to later handling when necessary.

This patch fixes a problem with rx handling on multiple interfaces. Especially when using hardware-scanning and a wireless driver (i.e. iwlwifi) which is able to receive data while scanning. The rx handlers can modify the skb and the frame control field (see ieee80211_rx_h_remove_qos_control) but since every interface gets its own copy of the skb each should get its own copy of rx.fc too. In my case the wlan0-interface did not remove the qos-control from the frame because the corresponding flag in rx.fc was already removed while processing the frame on the master interface. Therefore somehow corrupted frames were passed to the userspace. Signed-off-by:

The function sockfd_lookup uses fget on the value that is stored in the file field of the returned structure, so fput should ultimately be applied to this value. This can be done directly, but it seems better to use the specific macro sockfd_put, which does the same thing. The problem was fixed using the following semantic patch. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression s; @@ s = sockfd_lookup(...) ... + sockfd_put(s); ?- fput(s->file); // </smpl> Signed-off-by:

Since __xfrm_policy_destroy is used to destory the resources allocated by xfrm_policy_alloc. So using the name __xfrm_policy_destroy is not correspond with xfrm_policy_alloc. Rename it to xfrm_policy_destroy. And along with some instances that call xfrm_policy_alloc but not using xfrm_policy_destroy to destroy the resource, fix them. Signed-off-by:
