* iwi: migrate to new net80211 encryption key APIAdrian Chadd2026-02-261-2/+3

* net80211: convert the rest of the native net80211 drivers to SEQNO_OFFLOADAdrian Chadd2025-09-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | * 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.)

| | | | | | | | | | | | | | | | | | | | | | | - 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.

| | | | | | | | | | | | | | | | | | Uses of mallocarray(9). The use of mallocarray(9) has rocketed the required swap to build FreeBSD. This is likely caused by the allocation size attributes which put extra pressure on the compiler. Given that most of these checks are superfluous we have to choose better where to use mallocarray(9). We still have more uses of mallocarray(9) but hopefully this is enough to bring swap usage to a reasonable level. Reported by: wosch PR: 225197 Notes: svn path=/head/; revision=328218
* dev: make some use of mallocarray(9).Pedro F. Giffuni2018-01-131-2/+2
| | | | | | | | | | | | | | Focus on code where we are doing multiplications within malloc(9). None of these is likely to overflow, however the change is still useful as some static checkers can benefit from the allocation attributes we use for mallocarray. This initial sweep only covers malloc(9) calls with M_NOWAIT. No good reason but I started doing the changes before r327796 and at that time it was convenient to make sure the sorrounding code could handle NULL values. Notes: svn path=/head/; revision=327949
* [net80211] convert all of the WME use over to a temporary copy of WME info.Adrian Chadd2018-01-021-5/+5
| | | | | | | | | | | | | | | | | | | | This removes the direct WME info access in the ieee80211com struct and instead provides a method of fetching the data. Right now it's a no-op but eventually it'll turn into a per-VAP method for drivers that support it (eg iwn, iwm, upcoming ath10k work) as things like p2p support require this kind of behaviour. Tested: * ath(4), STA and AP mode TODO: * yes, this is slightly stack size-y, but it is an important first step to get drivers migrated over to a sensible WME API. A lot of per-phy things need to be converted to per-VAP before P2P, 11ac firmware, etc stuff shows up. Notes: svn path=/head/; revision=327479
* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-273-0/+6
| | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
