Commit 6623e3b2 (ipv4: IP defragmentation must be ECN aware) was an attempt to not lose "Congestion Experienced" (CE) indications when performing datagram defragmentation. Stefanos Harhalakis raised the point that RFC 3168 requirements were not completely met by this commit. In particular, we MUST detect invalid combinations and eventually drop illegal frames.

Currently the devices that have already stripped IEEE 802.11 header from the AMSDU SKB can not use ieee80211_amsdu_to_8023s routine. This patch enhances ieee80211_amsdu_to_8023s() API by changing mandatory removing of IEEE 802.11 header from AMSDU to optional.

some times the rssi control descriptor for the main antenna may be negative like that of alternate antenna, hence before incrementing packet counts/rssi of main/alternate antenna make sure both main_rssi and alt_rssi are positive only. this avoids wrong selection of antenna due to diversity Cc: Gabriel Tseng <Gabriel.Tseng@Atheros.com> Cc: Senthilkumar Balasubramanian <Senthilkumar.Balasubramanian@Atheros.com> Signed-off-by: NMohammed Shafi Shajakhan <mshajakhan@atheros.com> Signed-off-by: NJohn W.

The list_for_each_entry loop can fail, in which case the list element is not removed from the list rfkill_fds. Since this list is not accessed by the loop, the addition of &data->list into the list is just moved after the loop.

This adds sparse RCU annotations to most of mac80211, only the mesh code remains to be done. Due the the previous patches, the annotations are pretty simple. The only thing that this actually changes is removing the RCU usage of key->sta in debugfs since this pointer isn't actually an RCU-managed pointer (it only has a single assignment done before the key even goes live). As that is otherwise harmless, I decided to make it part of this patch. Signed-off-by: NJohannes Berg <johannes.berg@intel.com> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

During my quest to make mac80211 not have any RCU warnings from sparse, I came across the a-MPDU code again and it wasn't quite clear why it isn't racy. So instead of assigning the tid_tx array with just the spinlock held in ieee80211_start_tx_ba_session use a separate temporary array protected only by the spinlock and protect all assignments to the "live" array by both the spinlock and the mutex so that other code is easily verified to be correct. Due to pointer assignment atomicity I don't think this is a real issue, but I'm not sure, especially on Alpha the current code might be problematic.

Add the ability to advertise interface combinations in nl80211. This allows the driver to indicate what the combinations are that it supports. "Combinations" of just a single interface are implicit, as previously. Note that cfg80211 will enforce that the restrictions are met, but not for all drivers yet (once all drivers are updated, we can remove the flag and enforce for all). When no combinations are actually supported, an empty list will be exported so that userspace can know if the kernel exported this info or not (although it isn't clear to me what tools using the info should do if the kernel didn't export it). Since some interface types are purely virtual/software and don't fit the restrictions, those are exposed in a new list of pure SW types, not subject to restrictions. This mainly exists to handle AP-VLAN and monitor interfaces in mac80211. Signed-off-by: NJohannes Berg <johannes.berg@intel.com> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

udp_ioctl() really handles UDP and UDPLite protocols. 1) It can increment UDP_MIB_INERRORS in case first_packet_length() finds a frame with bad checksum. 2) It has a dependency on sizeof(struct udphdr), not applicable to ICMP/PING If ping sockets need to handle SIOCINQ/SIOCOUTQ ioctl, this should be done differently.
