2020-11-06mac80211: add radiotap flag to assure frames are not reorderedMathy Vanhoef1-0/+1
Add a new radiotap flag to indicate injected frames must not be reordered relative to other frames that also have this flag set, independent of priority field values in the transmitted frame. Parse this radiotap flag and define and set a corresponding Tx control flag. Note that this flag has recently been standardized as part of an update to radiotap.

2020-07-31mac80211: add radiotap flag to prevent sequence number overwriteMathy Vanhoef1-0/+1
The radiotap specification contains a flag to indicate that the sequence number of an injected frame should not be overwritten. Parse this flag and define and set a corresponding Tx control flag.

2019-02-22Merge tag 'wireless-drivers-next-for-davem-2019-02-22' of ↵David S. Miller1-0/+6
git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for 5.1 Most likely the last set of patches for 5.1. WPA3 support to ath10k and qtnfmac. FTM support to iwlwifi and ath10k. And of course other new features and bugfixes. wireless-drivers was merged due to dependency in mt76. Major changes: iwlwifi * HE radiotap * FTM (Fine Timing Measurement) initiator and responder implementation * bump supported firmware API to 46 * VHT extended NSS support * new PCI IDs for 9260 and 22000 series ath10k * change QMI interface to support the new (and backwards incompatible) interface from HL3.1 and used in recent HL2.0 branch firmware releases * support WPA3 with WCN3990 * support for mac80211 airtime fairness based on transmit rate estimation, the firmware needs to support WMI_SERVICE_PEER_STATS to enable this * report transmit airtime to mac80211 with firmwares having WMI_SERVICE_REPORT_AIRTIME feature, this to have more accurate airtime fairness based on real transmit time (instead of just estimated from transmit rate) * support Fine Timing Measurement (FTM) responder role * add dynamic VLAN support with firmware having WMI_SERVICE_PER_PACKET_SW_ENCRYPT * switch to use SPDX license identifiers ath * add new country codes for US brcmfmac * support monitor frames with the hardware/ucode header qtnfmac * enable WPA3 SAE and OWE support mt76 * beacon support for USB devices (mesh+ad-hoc only) rtlwifi * convert to use SPDX license identifiers libertas_tf * get the MAC address before registering the device ==================== Signed-off-by: David S.

2018-09-05mac80211: support reporting 0-length PSDU in radiotapShaul Triebitz1-0/+6
For certain sounding frames, it may be useful to report them to userspace even though they don't have a PSDU in order to determine the PHY parameters (e.g. VHT rate/stream config.)

2017-01-25wireless: radiotap: rewrite the radiotap header fileJohannes Berg1-298/+157
The header file has grown a lot of #define's etc, but they are nicer as enums, so rewrite the file from the documentation as such. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2016-09-12mac80211: add support for radiotap timestamp fieldJohannes Berg1-0/+21
Use the existing device timestamp from the RX status information to add support for the new radiotap timestamp field. Currently only 32-bit counters are supported, but we also add the radiotap mactime where applicable. This new field allows more flexibility in where the timestamp is taken etc. The non-timestamp data in the field is taken from a new field in the hw struct.

2014-02-06mac80211: propagate STBC / LDPC flags to radiotapEmmanuel Grumbach1-0/+4
This capabilities weren't propagated to the radiotap header. We don't set here the VHT_KNOWN / MCS_HAVE flag because not all the low level drivers will know how to properly flag the frames, hence the low level driver will be in charge of setting IEEE80211_RADIOTAP_MCS_HAVE_FEC, IEEE80211_RADIOTAP_MCS_HAVE_STBC and / or IEEE80211_RADIOTAP_VHT_KNOWN_STBC according to its capabilities.

2013-07-16mac80211: add radiotap flag and handling for 5/10 MHzSimon Wunderlich1-0/+4
Wireshark already defines radiotap channel flags for 5 and 10 MHz, so just use them in Linux radiotap too. Furthermore, add rx status flags to allow drivers to report when they received data on 5 or 10 MHz channels.

2013-05-24mac80211: add STBC flag for radiotapOleksij Rempel1-0/+7
Some chips can tell us if received frame was encoded with STBC or not. To make this information available in user space we can use updated radiotap specification: http://www.radiotap.org/defined-fields/MCS This patch will set number of STBC encoded spatial streams (Nss). The HAVE_STBC flag should be provided by driver. Signed-off-by: Oleksij Rempel <linux@rempel-privat.de> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2011-11-11wireless: move ieee80211chan2mhz macroJohannes Berg1-8/+0

2010-02-08wireless: update radiotap parserJohannes Berg1-0/+4
Upstream radiotap has adopted the namespace proposal David Young made and I then took care of, for which I had adapted the radiotap parser as a library outside the kernel.

2009-10-30mac80211: fix radiotap header generationJohannes Berg1-1/+1
In commit 601ae7f25aea58f208a7f640f6174aac0652403a Author: Bruno Randolf <br1@einfach.org> Date: Thu May 8 19:22:43 2008 +0200 mac80211: make rx radiotap header more flexible code was added that tried to align the radiotap header position in memory based on the radiotap header length. Quite obviously, that is completely useless. Instead of trying to do that, use unaligned accesses to generate the radiotap header. To properly do that, we also need to mark struct ieee80211_radiotap_header packed, but that is fine since it's already packed (and it should be marked packed anyway since its a wire format).
