* Make ifconfig(8) display whether bwfm(4) firmware is using 802.11ac.stsp2019-02-191-1/+2

* Rename some data frame subtype macros to make the difference betweenstsp2019-01-151-7/+7
| | | | | | "data" and "no data" frames more obvious. These renamed macros aren't actually used anywhere in net80211 yet. cross-checked with 802.11 specs by myself and Lauri Tirkkonen

* ADDBA frames have a parameter set which we check against our own capabilitiesstsp2016-01-041-1/+11
| | | | | | but we were checking bits in these parameters with the wrong set of bitmasks. Negotiating A-MPDUs with some APs failed because of this bug. ok kettenis@

| | | | | | | ieee80211com and move them inside #ifndef IEEE80211_NO_HT without breaking the build in rsu(4) for RAMDISK_CD. Also declare 11n protection modes and MCS count. ok deraadt mpi kettenis guenther

* In ieee80211.h update references to standard sections to 802.11-2012.stsp2015-07-141-46/+200
| | | | | | | | Add missing element IDs (and remove some non-standard ones), action field categories and values, some 11n related stuff, and other small things. Use the same element ID symbolic names as FreeBSD where applicable as suggested by millert. ok mpi millert

* Block Ack agreements are unidirectional.damien2009-01-281-2/+7
| | | | | | | | | | Maintain state for both originator and recipient roles separately. Do not allocate receive reordering buffer in addba_request(). Test the "initiator" bit in incoming DELBA frames and set it appropriately in outgoing DELBA frames. Separate callbacks for Tx/Rx too. no binary change since all this is #ifdef'ed out.
* Add some initial HT bits (not enabled yet) based on 802.11n Draft 7.01:damien2009-01-261-12/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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 some inline functions to test the presence of optional 802.11damien2008-09-271-1/+55
| | | | | | | | | | | | | | | | header fields (Sequence Control, Address 4, QoS Control, +HTC) and use them where appropriate. 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).
* add ic_tid_noack bitmap to indicate a per-TID ACK policy (1=no ack,damien2008-09-011-2/+7
| | | | | | 0=normal ack). all bits are currently set to 0. use this bitmap to set the ACK policy of the QoS control field of outgoing QoS frames.
* move definitions of channels attributes away from ieee80211.h suchdamien2008-08-271-32/+1
| | | | | | | | | | that ieee80211.h contains only definitions that are part of the 802.11 standard and not constants used internally by net80211. because channels attributes are exported to userland through the radiotap BPF interface, add the definitions to ieee80211_radiotap.h too (which must be kept in sync with what is used in net80211). also, do not export combinations of channel attributes to userland so that noone get stupid ideas.
* add a couple of new definitions (action frames, new subtypes for controldamien2008-08-121-4/+37
| | | | frames, new IEs etc...)
* add/process group integrity cipher suite in RSN IEs.damien2008-08-121-2/+4
| | | | add support for MFP negotiation during association.
* add support for EAPOL-Key v3 descriptors (similar to v2 except that thedamien2008-08-121-1/+2
| | | | | MIC is computed using AES-128-CMAC instead of HMAC-SHA1). add a SHA-256 based key derivation function (not used yet).

* process IGTK KDEs in EAPOL-Key frames and install integrity group keysdamien2008-08-121-2/+3

* Welcome BIP: the Broadcast/Multicast Integrity Protocol defineddamien2008-08-121-1/+3
| | | | | | | in Draft IEEE P802.11w. It provides data integrity and replay protection for broadcast/ multicast robust management frames (not used yet) using AES-128 in CMAC mode.

* Kernel implementation of the 4-way handshake and group-keydamien2008-04-161-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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@

* all WPA implementations i have tested use EAPOL-Key frames version 1,damien2007-08-011-2/+6
| | | | | | | | | so use that too and remove a check in ieee80211_recv_eapol(). WPA1 stores the group key id into bits 4-5 of the EAPOL-Key frame info field and uses bit 6 to indicate if the key is Rx/Tx or Rx only. remove a check in ieee80211_eapol_key_decrypt() because WPA1 encrypts the payload of message 1 of the group-key handshake without setting the encrypted bit in the info field.
* WPA1 uses its own (non-standard) EAPOL-Key descriptor type.damien2007-07-281-4/+17

| | | | | | | | | | functions into the two drivers that use them (atw and rtw.) this code is not generic enough to be used by other drivers and there is no chance that it will ever be used in newer driver since it supports 802.11b only. plus, it hurts my eyes each time i look into ieee80211_output.c.
