2011-11-09nl80211: add API to probe a clientJohannes Berg
When the AP SME in hostapd is used it wants to probe the clients when they have been idle for some time. Add explicit API to support this. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-11-09nl80211: advertise device AP SMEJohannes Berg
Add the ability to advertise that the device contains the AP SME and what features it can support. There are currently no features in the bitmap -- probe response offload will be advertised by a few patches Arik is working on now (who took over from Guy Eilam) and a device with AP SME will typically implement and require response offload.

2011-11-09nl80211: allow subscribing to unexpected class3 framesJohannes Berg
To implement AP mode without monitor interfaces we need to be able to send a deauth to stations that send frames without being associated. Enable this by adding a new nl80211 event for such frames that an application can subscribe to. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2011-11-09mac80211: add helper to free TX skbJohannes Berg
Drivers that need to drop a frame before it can be transmitted will usually simply free that frame. This is currently fine, but in the future it'll be needed to tell mac80211 about this case, so add a new routine that frees a TX skb.

2011-11-09mac80211: simplify mesh frame queue mapping and QoSJavier Cardona
We only need to set the skb queue twice: 1. by the netdev, on local TX. 2. when forwarding a mesh frame. We only need to set the qos header twice: 1. by mac80211, on local TX. 2. when putting a frame on the mpath->frame_queue We also don't need the RA in order to set the proper queue mapping since all mesh STAs are QoS, indicate this and do it once when the frame is received. Also fixes an issue where the QoS header and queue mapping was not set for unicast forwarded frames.

2011-11-09mac80211: check if frame is really part of this BAThomas Pedersen
There was an an implicit assumption that any QoS data frame received from a STA/TID with an active BA session was sent to this vif as part of a BA. This is not true if IFF_PROMISC is enabled and the frame was destined for a different peer, for example. Don't treat these frames as part of a BA from the sending STA.

2011-11-09mac80211: QoS multicast frames have No Ack policyThomas Pedersen
Previously QoS multicast frames had the Normal Acknowledgment QoS control bits set. This would cause broadcast frames to be discarded by peers with which we have a BA session, since their sequence number would fall outside the allowed range. Set No Ack QoS control bits on multicast QoS frames and filter these in de-aggregation code.

2011-11-09ipv4: reduce percpu needs for icmpmsg mibsEric Dumazet
Reading /proc/net/snmp on a machine with a lot of cpus is very expensive (can be ~88000 us). This is because ICMPMSG MIB uses 4096 bytes per cpu, and folding values for all possible cpus can read 16 Mbytes of memory. ICMP messages are not considered as fast path on a typical server, and eventually few cpus handle them anyway. We can afford an atomic operation instead of using percpu data. This saves 4096 bytes per cpu and per network namespace. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-09mac80211: Avoid filling up mesh preq queue with redundant requestsJavier Cardona
Don't accept redundant PREQs for a given destination. This fixes a problem under high load: kernel: [20386.250913] mesh_queue_preq: 235 callbacks suppressed kernel: [20386.253335] Mesh HWMP (mesh0): PREQ node queue full kernel: [20386.253352] Mesh HWMP (mesh0): PREQ node queue full (...) The 802.11s protocol has a provision to limit the rate of path requests (PREQs) are transmitted (dot11MeshHWMPpreqMinInterval) but there was no limit on the rate at which PREQs were being queued up. There is a valid reason for queuing PREQs: this way we can even out PREQ bursts. But queueing multiple PREQs for the same destination is useless.

2011-11-09net: add wireless TX status socket optionJohannes Berg
The 802.1X EAPOL handshake hostapd does requires knowing whether the frame was ack'ed by the peer. Currently, we fudge this pretty badly by not even transmitting the frame as a normal data frame but injecting it with radiotap and getting the status out of radiotap monitor as well. This is rather complex, confuses users (mon.wlan0 presence) and doesn't work with all hardware. To get rid of that hack, introduce a real wifi TX status option for data frame transmissions. This works similar to the existing TX timestamping in that it reflects the SKB back to the socket's error queue with a SCM_WIFI_STATUS cmsg that has an int indicating ACK status (0/1). Since it is possible that at some point we will want to have TX timestamping and wifi status in a single errqueue SKB (there's little point in not doing that), redefine SO_EE_ORIGIN_TIMESTAMPING to SO_EE_ORIGIN_TXSTATUS which can collect more than just the timestamp; keep the old constant as an alias of course. Currently the internal APIs don't make that possible, but it wouldn't be hard to split them up in a way that makes it possible. Thanks to Neil Horman for helping me figure out the functions that add the control messages. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

The AH4/6 ahash output callbacks pass nexthdr to xfrm_output_resume instead of the error code. This appears to be a copy+paste error from the input case, where nexthdr is expected. This causes the driver to continuously add AH headers to the datagram until either an allocation fails and the packet is dropped or the ahash driver hits a synchronous fallback and the resulting monstrosity is transmitted.

2011-11-09cfg80211: fix bug on regulatory core exit on access to last_requestLuis R. Rodriguez
Commit 4d9d88d1 by Scott James Remnant <keybuk@google.com> added the .uevent() callback for the regulatory device used during the platform device registration. The change was done to account for queuing up udev change requests through udevadm triggers. The change also meant that upon regulatory core exit we will now send a uevent() but the uevent() callback, reg_device_uevent(), also accessed last_request. Right before commiting device suicide we free'd last_request but never set it to NULL so platform_device_unregister() would lead to bogus kernel paging request. Fix this and also simply supress uevents right before we commit suicide as they are pointless. This fix is required for kernels >= v2.6.39 $ git describe --contains 4d9d88d1 v2.6.39-rc1~468^2~25^2^2~21 The impact of not having this present is that a bogus paging access may occur (only read) upon cfg80211 unload time. You may also get this BUG complaint below.

If there are no cooked monitor interfaces, there's no point in building the radiotap RX header for the frame and iterating the interface list. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-11-08mac80211: fix confusing parenthesesJohannes Berg
There's an extra pair of parentheses here that is simply confusing because it implies a nesting that doesn't actually exist. Just remove it. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-11-08mac80211: call set_wmm_default only for valid vifsEliad Peller
mac80211 calls ieee80211_set_wmm_default (which in turn calls drv_conf_tx()) for every new interface, including "internal" ones (e.g. monitor interface, which the low-level driver doesn't know about). Limit this call only to valid interfaces. Reported-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W.

2011-11-08net: make ipv6 PKTINFO honour freebindMaciej Żenczykowski
This just makes it possible to spoof source IPv6 address on a socket without having to create and bind a new socket for every source IP we wish to spoof. Signed-off-by: Maciej Żenczykowski <maze@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-08net: make ipv6 bind honour freebindMaciej Żenczykowski
This makes native ipv6 bind follow the precedent set by: - native ipv4 bind behaviour - dual stack ipv4-mapped ipv6 bind behaviour. This does allow an unpriviledged process to spoof its source IPv6 address, just like it currently can spoof its source IPv4 address (for example when using UDP).
