* WiFi: fix ieee80211_media_change() callersBjoern A. Zeeb2020-09-071-11/+2
| | | | | | | | | | | | | | | | | | | | | In r178354 with the introduction of multi-bss ("vap") support factoring out started and with r193340 ieee80211_media_change() no longer returned ENETRESET but only 0 or error. As ieee80211(9) tells the ieee80211_media_change() function should not be called directly but is registered with ieee80211_vap_attach() instead. Some drivers have not been fully converted. After fixing the return checking some of these functions were simply wrappers between ieee80211_vap_attach() and ieee80211_media_change(), so remove the extra function, where possible as well.

* Widen EPOCH(9) usage in PCI WLAN drivers.Hans Petter Selasky2020-01-301-0/+3
| | | | | | | | | | | | | | Make sure all occurrences of ieee80211_input_xxx() in sys/dev are covered by a network epoch section. Do not depend on the interrupt handler nor any taskqueues being in a network epoch section. This patch should unbreak the PCI WLAN drivers after r357004.

* Fix ieee80211_radiotap(9) usage in wireless drivers:Andriy Voskoboinyk2019-03-112-11/+2
| | | | | | | | | | | | | | | | | | | | | | | - 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.

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

* net80211: ieee80211_ratectl*: switch to reusable KPIAndriy Voskoboinyk2016-10-021-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace various void * / int argument combinations with common structures: - ieee80211_ratectl_tx_status for *_tx_complete(); - ieee80211_ratectl_tx_stats for *_tx_update(); While here, improve amrr_tx_update() for a bit: 1. In case, if receiver is not known (typical for Ralink USB drivers), refresh Tx rate for all nodes on the interface. 2. There was a misuse: - otus(4) sends non-decreasing counters (as originally intended); - but ural(4), rum(4) and run(4) are using 'read & clear' registers to obtain statistics for some period of time (and those 'last period' values are used as arguments for tx_update()). If arguments are not big enough, they are just discarded after the next call. Fix: move counting into *_tx_update() (now otus(4) will zero out all node counters after every tx_update() call) Tested with: - Intel 3945BG (wpi(4)), STA mode. - WUSB54GC (rum(4)), STA / HOSTAP mode. - RTL8188EU (urtwn(4)), STA mode.

* Replay r286410. Change KPI of how device drivers that provide wirelessGleb Smirnoff2015-08-275-276/+201
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Only if a driver calls ieee80211_ratectl_init() check if the NONE algo is still selected and try to use AMRR in that case. Drivers are still free to use any other algo by calling ieee80211_ratectl_set() prior to the ieee80211_ratectl_init() call. After this change it is now safe to assume that a ratectl algo is always available and selected, which renders the IEEE80211_C_RATECTL flag pretty much useless. Therefore revert r211314 and 211546.
