Add initial 802.11ac (VHT) support to net80211. Add VHT capability and operation IE definitions to ieee80211.h. Introduce channel flags to identify 80MHz and 160MHz capable channels. Parse VHT IEs in beacons, announce the driver's VHT capabilities in probe requests and assoc requests, and hop into 11ac mode after association to the AP if possible. Enable VHT by default if the driver announces support for it. ok claudio@

Defer rtm_80211info() call from ieee80211_set_link_state() to a task context. Sending routing messages requires a socket lock which may sleep. ieee80211_set_link_state() is called from interrupts and timeouts where sleeping is not allowed. mvs@ pointed out that if_link_state_change() is already using a task for this reason. Should fix a witness-related panic reported by cheloha@ ok mvs@ tobhe@ florian@

Make wireless drivers call if_input() only once per interrupt. This reduces drops caused by the ifq pressure drop mechanism and hence increases throughput. Such drops are visible with e.g. 'netstat -dnI iwm0'. Not all affected drivers have been tested yet but these changes are largely mechanical and should be safe. As usual, please report any regressions. With help from dlg@ and mpi@ Problem found by robert@ Tested by robert, jmc, Tracey Emer, Matthias Schmidt, florian, Björn Ketelaars ok mpi@

Add support for 802.11n Tx aggregation to net80211 and the iwn(4) driver. In particular, add Tx block ack session management to net80211, with enough funcionality to support Tx aggregation on devices which perform A-MPDU subframe scheduling in firmware. Make use of the iwn(4) firmware Tx scheduler to build A-MPDUs. net80211's QoS support code is now enabled and used by Tx aggregation. A-MSDU frames inside A-MPDUs have been tested and work in principle. For now, this feature is disabled because unfair TCP connection sharing was observed during testing, where bursts of TCP Ack frames for a single tcpbench(1) connection arriving in A-MSDUs made other TCP connections stall. Switch off support for A-MSDUs inside A-MPDUs on the Rx side as well. Tested on iwn chipsets 1000, 4965, 5100, 5300, 2200, 6200, 6205, 6300 (committed version of tested diff has all debug printfs removed) tests/ok benno kmos mlarkin kevlo

Add a new function hook to struct ieee80211com which wireless drivers can use to process, and then acknowledge or reject, incoming AUTH requests in hostap mode. net80211 accepts an AUTH request from any STA which fits into the node cache. This behaviour doesn't work for devices which have a lower limit on concurrent STAs they can serve, so such drivers need an override. This will be used by our athn(4) USB driver soon. ok kevlo@

When processing an ADDBA request, iwm(4) runs a task which sends a command to the firmware and waits for confirmation. This command can fail and there was no way we could recover from such an error. Allow drivers to return EBUSY from their ic_ampdu_rx_start() handler to tell the stack not to send a confirmation just yet. The stack provides functions which the driver can call to accept or refuse the request. There is no functional change yet. This just shuffles code around so drivers may insert themselves into the process. ok mpi@

Block Ack agreements are unidirectional. Maintain state for both originator and recipient roles separately. Do not allocate receive reordering buffer in addba_request().

Add some initial HT bits (not enabled yet) based on 802.11n Draft 7.01: - implement A-MPDU frames buffering and reordering - implement A-MSDU decapsulation - process/send ADDBA Request, ADDBA Response and DELBA action frames - process Block Ack Request control frames (including MTBAR) - implement PBAC support (Protected Block Ack) - add some incomplete HT Capabilities and HT Operation IEs parsing Add more Management Frame Protection bits based on 802.11w Draft 7.0: - implement SA Query procedure (both AP and STA) - cleanup BIP Fix some bugs: - fix check for WEP key length that otherwise caused a stack smash in ieee80211_wep_encrypt (pointed out by Xavier Santolaria on macppc) - properly stop EAPOL timeout: fixes a panic that occured in HostAP mode when turning the interface down while a 4-way handshake is in progress (pointed out by Doughertys) Did some code cleanup too. The HT bits are currently not compiled in (IEEE80211_NO_HT is defined) because they won't be ready until after the next release and I didn't want to grow the kernel or to inadvertently introduce new bugs. They are here such that other people can look at the code. Notice that I had to add an extra parameter to ic_send_mgmt() for action frames, that is why there are small changes in drivers defining their own ic_send_mgmt() handler. Sorry for the not very incremental diff but this has been sitting in my tree for too long now.

Add ieee80211_get_qos() inline function to extract the QoS control field of an 802.11 header instead of duplicating the same scary code everywhere (the location of this field depends on the presence of an Address 4 field). Export ieee80211_up_to_ac() so that drivers can select the access category to use based on the TID subfield of the QoS Control field. Define more QoS-related bits for the RSN Capabilities field of RSN IE (will be used later).

Change the way we process EAPOL-Key frames. Free the mbuf in the ieee80211_eapol_key_input() function. Do not assume the frame is contiguous, call m_pullup2() if it is not. We need the frame to be contiguous to process KDEs efficiently in EAPOL-Key frames (just like we process IEs in management frames). However, there are drivers like upgt(4) that use m_devget() in the RX path. m_devget() can return fragmented mbuf chains. Notice that we should do the same m_pullup2() for management frames. This will be done later. Remove the ic_recv_eapol callback.

Kernel implementation of the 4-way handshake and group-key handshake protocols (both supplicant and authenticator state machines) as defined in the IEEE 802.11i standard. Software implementation of the TKIP (Temporal Key Integrity Protocol) and CCMP (CTR with CBC-MAC Protocol) protocols. This diff doesn't implement any of the 802.1X authentication protocols and thus only PSK authentication (using pre-shared keys) is currently supported. In concrete terms, this adds support for WPA-PSK and WPA2-PSK protocols, both in station and hostap modes. The following drivers are marked as WPA-capable and should work: bwi(4), malo(4), ral(4), iwn(4), wpi(4), ural(4), rum(4), upgt(4), and zyd(4) The following options have been added to ifconfig(8): wpa, wpapsk, wpaprotos, wpaakms, wpaciphers, wpagroupcipher wpa-psk(8) can be used to generate keys from passphrases. tested by many@ ok deraadt@

From dyoung@NetBSD: ieee80211.h r 1.9 #define the difference in microseconds between a fast and a slow preamble and PLCP header. ieee80211_output.c r 1.19 Fix a bug in ieee80211_compute_duration: the 802.11 Duration field in an 802.11 unicast data packet is equal to the duration of the SIFS and Acknowledgement. That is, the amount of time reserved *after* the packet has finished transmitting. Change the arguments to ieee80211_compute_duration: pass the entire packet length, not just the payload length. Add a 'debug' argument to ieee80211_compute_duration and its helper subroutine, ieee80211_compute_duration1. If debug != 0, ieee80211_compute_duration printfs its arguments and several local variables. In rtw(4), load the 802.11 Duration field with the result from ieee80211_compute_duration.

From dyoung@NetBSD: Define for more bits in the Service field of the 802.11 PLCP Header. For use by the subroutine ieee80211_compute_duration, add struct ieee80211_duration, and #define a number of microsecond constants used for the transmit timing of 802.11 packets. Add the subroutine ieee80211_compute_duration, which computes for any packet the appropriate 802.11 Duration field, the PLCP Length field, as well as the Duration and Length fields for an RTS frame. atw(4), rtw(4), future drivers, and possibly ath(4) will share ieee80211_compute_duration. ok millert@
