2025-09-19net80211: convert the rest of the native net80211 drivers to SEQNO_OFFLOADAdrian Chadd
* Convert the rest of the drivers to implement driver/offloaded sequence number handling. * For drivers that implement their own sequence number space handling for A-MPDU, only call ieee80211_output_seqno_assign() if the frame isn't tagged with M_AMPDU_MPDU, which mirrors the original net80211 sequence number behaviour. (Except of course, the assignment is now happening during final encap/transmit, not early in encap.)

2019-03-11Fix ieee80211_radiotap(9) usage in wireless drivers:Andriy Voskoboinyk
- 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.

2018-09-26Reapply, with minor tweaks, r338025, from the original commit:Warner Losh
Remove unused and easy to misuse PNP macro parameter Inspired by r338025, just remove the element size parameter to the MODULE_PNP_INFO macro entirely. The 'table' parameter is now required to have correct pointer (or array) type. Since all invocations of the macro already had this property and the emitted PNP data continues to include the element size, there is no functional change. Mostly done with the coccinelle 'spatch' tool: $ cat modpnpsize0.cocci @normaltables@ identifier b,c; expression a,d,e; declarer MODULE_PNP_INFO; @@ MODULE_PNP_INFO(a,b,c,d, -sizeof(d[0]), e); @singletons@ identifier b,c,d; expression a; declarer MODULE_PNP_INFO; @@ MODULE_PNP_INFO(a,b,c,&d, -sizeof(d), 1); $ rg -l MODULE_PNP_INFO -- sys | \ xargs spatch --in-place --sp-file modpnpsize0.cocci (Note that coccinelle invokes diff(1) via a PATH search and expects diff to tolerate the -B flag, which BSD diff does not.

2017-11-27sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni
Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. 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. Notes: svn path=/head/; revision=326255

2015-08-27Replay r286410. Change KPI of how device drivers that provide wirelessGleb Smirnoff
connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers.

sleepable context for net80211 driver callbacks. This removes the need for USB and firmware based drivers to roll their own code to defer the chip programming for state changes, scan requests, channel changes and mcast/promisc updates. When a driver callback completes the hardware state is now guaranteed to have been updated and is in sync with net80211 layer. This nukes around 1300 lines of code from the wireless device drivers making them more readable and less race prone. The net80211 layer has been updated as follows - all state/channel changes are serialised on the taskqueue. - ieee80211_new_state() always queues and can now be called from any context - scanning runs from a single taskq function and executes to completion. driver callbacks are synchronous so the channel, phy mode and rx filters are guaranteed to be set in hardware before probe request frames are transmitted.
