* Make wireless drivers call if_input() only once per interrupt.stsp2019-09-121-2/+4
| | | | | | | | | | | | | | This reduces drops caused by the ifq pressure drop mechanism and hence increases throughput. Such drops are visible with e.g. 'netstat -dnI iwm0'. Not all affected drivers have been tested yet but these changes are largely mechanical and should be safe. As usual, please report any regressions.

* replace IFF_OACTIVE manipulation with mpsafe operations.dlg2015-11-251-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | there are two things shared between the network stack and drivers in the send path: the send queue and the IFF_OACTIVE flag. the send queue is now protected by a mutex. this diff makes the oactive functionality mpsafe too. IFF_OACTIVE is part of if_flags. there are two problems with that. firstly, if_flags is a short and we dont have any MI atomic operations to manipulate a short. secondly, while we could make the IFF_OACTIVE operates mpsafe, all changes to other flags would have to be made safe at the same time, otherwise a read-modify-write cycle on their updates could clobber the oactive change. instead, this moves the oactive mark into struct ifqueue and provides an API for changing it. there's ifq_set_oactive, ifq_clr_oactive, and ifq_is_oactive. these are modelled on ifsq_set_oactive, ifsq_clr_oactive, and ifsq_is_oactive in dragonflybsd. this diff includes changes to all the drivers manipulating IFF_OACTIVE to now use the ifsq_{set,clr_is}_oactive API too. ok kettenis@ mpi@ jmatthew@ deraadt@

| | | | | | | | | remove IBSS and HostAP support from net80211 and 802.11 drivers. it can be used to shrink RAMDISK kernels for instance (like what was done for wi(4)). it also has the benefit of highlighting what is specific to IBSS and HostAP modes in the code. the cost is that we now have two code paths to maintain.

* Kernel implementation of the 4-way handshake and group-keydamien2008-04-161-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | handshake protocols (both supplicant and authenticator state machines) as defined in the IEEE 802.11i standard. Software implementation of the TKIP (Temporal Key Integrity Protocol) and CCMP (CTR with CBC-MAC Protocol) protocols. This diff doesn't implement any of the 802.1X authentication protocols and thus only PSK authentication (using pre-shared keys) is currently supported. In concrete terms, this adds support for WPA-PSK and WPA2-PSK protocols, both in station and hostap modes. The following drivers are marked as WPA-capable and should work: bwi(4), malo(4), ral(4), iwn(4), wpi(4), ural(4), rum(4), upgt(4), and zyd(4) The following options have been added to ifconfig(8): wpa, wpapsk, wpaprotos, wpaakms, wpaciphers, wpagroupcipher wpa-psk(8) can be used to generate keys from passphrases. tested by many@ ok deraadt@
