* fixup inactivity timers:Sam Leffler2004-12-312-5/+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 Notes: svn path=/head/; revision=139528
* Relearn how WPA keying is supposed to work and fix WPA+WME whileSam Leffler2004-12-312-111/+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 Notes: svn path=/head/; revision=139527

* Add a new network interface flag, IFF_NEEDSGIANT, which will allowRobert Watson2004-07-272-2/+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. Notes: svn path=/head/; revision=132712

| | | | | | | | | | o The ieee80211_media_status() function updates the ifi_link_state field and calls rt_ifmsg() to notify listeners on the routing socket. Approved by: sam Notes: svn path=/head/; revision=128966

* Change handling of probe response frames. Previously we always dropped theSam Leffler2004-04-021-2/+27
| | | | | | | | | | | | | | refcnt on the node but left it in the node table. This allows the node table to hold the results of scanned ap's but for ibss scans left nodes w/o any driver-private state setup and/or a bad refcnt (when the nodes were timed out they were prematurely discarded). Now we treat nodes identified for ap scanning as before but force nodes discovered when scanning for ibss neighbors to have complete/proper state and hold the refcnt on the node. Any other nodes created because of these frames are discarded directly (need to optimize this case to eliminate various work that's immediately discarded). Notes: svn path=/head/; revision=127774
* fix adhoc/ibss operation for drivers that require host support (e.g. ath):Sam Leffler2004-04-024-36/+79
| | | | | | | | | | | | | | | o remove IEEE80211_C_RCVMGT capability o on transmit craft new nodes as needed using new ieee80211_find_txnode routine o add ieee80211_find_txnode routine to lookup a node by mac address and if not present create one when operating in ibss/ahdemo mode; new nodes are dup'd from bss and the driver is told to treat the node as if a new association has been created so driver-private state (e.g. rate control handling) is setup Obtained from: netbsd (basic idea) Notes: svn path=/head/; revision=127772
