* Simplify the logic for checking the scan candidates at the end of a scan.sam2005-01-181-20/+17
| | | | | | | | Hold a lock on the table instead of futzing with reference counts which was potentially dangerous except drivers were quiescent while we did this so the table contents never changed. Disable the hack logic for removing scan candidates with multiple association failures; it's never done the right thing and will be fixed correctly with background scanning goes in.

* fixup inactivity timers:sam2004-12-312-5/+7
| | | | | | | | | | | | | o ic_inact_auth is a bad name, it's the inactivity threshold for being associated but not authorized; use it that way o reset ni_inact when switching inactivity thresholds to minimize the race against the timer (don't want to lock for this stuff) o change the inactivity probe threshold from a one-shot to cover a range: when below this threshold but not expired send a probe each inactivity interval; should probably guard against the interval being turned way down as this could cause us to spam the net with probes
* Relearn how WPA keying is supposed to work and fix WPA+WME whilesam2004-12-312-111/+129
| | | | | | | | | | | | | | | | | we're at it: o WPA/802.11i has a unicast key and a group key; in station mode everything is sent with the unicast key--we were consulting the destination mac address and incorrectly using the group key o (perpetuate fallback use of the default tx key to maintain compatibility with the way wpa_supplicant works) o correct EAPOL encryption logic to check unicast key instead of assuming other state implies this o move QoS encapsulation up to before enmic work so TKIP has the information required to calculate the pseudo-header o do not do QoS-encapsulation of EAPOL frames as some ap's do the wrong thing with such frames (may need to revisit this if ap's start dropping non-QoS frames from stations assoc'd with QoS) o move ieee80211_mbuf_adjust closer to its caller

* Add a new network interface flag, IFF_NEEDSGIANT, which will allowrwatson2004-07-272-2/+2
| | | | | | | | | | | | | | | | | | | | | | device drivers to declare that the ifp->if_start() method implemented by the driver requires Giant in order to operate correctly. Add a 'struct task' to 'struct ifnet' that can be used to execute a deferred ifp->if_start() in the event that if_start needs to be called in a Giant-free environment. To do this, introduce if_start(), a wrapper function for ifp->if_start(). If the interface can run MPSAFE, it directly dispatches into the interface start routine. If it can't run MPSAFE, we're running with debug.mpsafenet != 0, and Giant isn't currently held, the task is queued to execute in a swi holding Giant via if_start_deferred(). Modify if_handoff() to use if_start() instead of direct dispatch. Modify 802.11 to use if_start() instead of direct dispatch. This is intended to provide increased compatibility for non-MPSAFE network device drivers in the presence of Giant-free operation via asynchronous dispatch. However, this commit does not mark any network interfaces as IFF_NEEDSGIANT.
