This includes an ath(4) update, some run(4) 11n support, 11n for otus(4), A-MPDU, A-MSDU, A-MPDU+A-MSDU and Fast frames options, scanning fixes, enahnced PRIV checks for jails, restored parent device name printing, improvements for upcoming VHT support, lots of under-the-hood infrastructure improvements, new device ID, debug tools updates, some whistespace changes (to make future MFCs easier). This does not include (nost) epoch(9) related changes as too much other infrastructure was not merged for that. Bump __FreeBSD_veresion as this changes the priv(9) names (not know to be used externally), and net80211 structures. Tested on: some ath(4) AP, run(4) STA, and rtwn(4) STA Discussed with: adrian (extremly briefly) Sponsored by: Rubicon Communications, LLC (d/b/a "Netgate") [partially] Relnotes: yes

Both an and wi don't do the modern cyrpto needed to use these cards on secure wifi networks. an needs firmware from Cisco, which I don't think was ever produced. wi could in theory do it with raw frames and on-host encryption, but nobody has written that in the 15 years since WEP was cracked.

Fix ieee80211_radiotap(9) usage in wireless drivers: - Alignment issues: * Add missing __packed attributes + padding across all drivers; in most places there was an assumption that padding will be always minimally suitable; in few places - e.g., in urtw(4) / rtwn(4) - padding was just missing. * Add __aligned(8) attribute for all Rx radiotap headers since they can contain 64-bit TSF timestamp; it cannot appear in Tx radiotap headers, so just drop the attribute here. Refresh ieee80211_radiotap(9) man page accordingly. - Since net80211 automatically updates channel frequency / flags in ieee80211_radiotap_chan_change() drop duplicate setup for these fields in drivers.

spdx: initial adoption of licensing ID tags.

2017-11-18T14:26:50Z

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Initially, only tag files that use BSD 4-Clause "Original" license. RelNotes: yes Differential Revision: https://reviews.freebsd.org/D13133
