* | | | mac80211: reassign channel contexts before stationsJohannes Berg2012-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since channel contexts are usually present before stations can be added to an interface, reassign before stations them in reconfiguration as well. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* | | | mac80211: clarify interface iteration and make it configurableJohannes Berg2012-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During hardware restart, all interfaces are iterated even though they haven't been re-added to the driver, document this behaviour. The same also happens during resume, which is even more confusing since all of the interfaces were previously removed from the driver. Make this optional so drivers relying on the current behaviour can still use it, but to let drivers that don't want this behaviour disable it. Also convert all API users, keeping the old semantics except in hwsim, where the new normal ones are desired. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* | | | mac80211: call driver method when restart completesJohannes Berg2012-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the driver requests a restart (reconfiguration) it gets all the normal method calls, but can't really tell why they're happening. Call a new restart_complete op in the driver when the restart completes, so it could keep its own state about the restart and clear it there. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* | | | mac80211: send deauth only with channel contextJohannes Berg2012-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When userspace asks to deauthenticate and we're just authenticated (or still authenticating) send a deauth frame instead of deleting the auth request. On the other hand, if we've just disassociated and therefore deleted all our state already, drop the deauth request because we no longer have a channel context to send it on.

* | | | mac80211: use a counter for remain-on-channel cookieJohannes Berg2012-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using the pointer which can be re-used fairly quickly due to allocator patterns and then makes debugging difficult, maintain a counter and use its value. Since it's a 64-bit value it can't really wrap, but catch that case anyway since it most likely points to a bug somewhere. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* | | | mac80211: combine status/drop reportingJohannes Berg2012-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TX status reporting is done for both the nl80211 report as well as the socket option. The socket option is also reported when an skb is dropped to guarantee that the copy in the IDR tree is freed and status is reported to userspace. However, when a frame is dropped, no nl80211 status is reported. This can cause userspace to stop making progress while waiting for a status notification. Combine the nl80211 and socket option status reporting into a new function and call it in both places -- when the status comes in from the driver and when the skb is dropped. While at it, also simplify the code in the nl80211 portion a bit. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* | | | mac80211: handle TX power per virtual interfaceJohannes Berg2012-10-30

The channel context introduction completely broke this though and in fact I had disabled TX power configuration there for drivers using channel contexts. Change everything to track TX power per interface so that different user settings and different channel maxima are treated correctly. Also continue tracking the global TX power though for compatibility with applications that attempt to configure the wiphy's TX power globally. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* | | | cfg80211: allow per interface TX power settingJohannes Berg2012-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TX power setting is currently per wiphy (hardware device) but with multi-channel capabilities that doesn't make much sense any more. Allow drivers (and mac80211) to advertise support for per-interface TX power configuration. When the TX power is configured for the wiphy, the wdev will be NULL and the driver can still handle that, but when a wdev is given the TX power can be set only for that wdev now.

| | | * | | mac80211: Fix FC masking in BIP AAD generationJouni Malinen2012-10-01

Fix this and to mask the correct fields. While doing so, convert the code to mask the full FC using IEEE80211_FCTL_* defines similarly to how CCMP AAD is built. Since BIP is used only with broadcast/multicast management frames, the Retry field is always 0 in these frames. The Protected field is also zero to maintain backwards compatibility. As such, the incorrect mask here does not really cause any problems for valid frames. In theory, an invalid BIP frame with Retry or Protected field set to 1 could be rejected because of BIP validation. However, no such frame should show up with standard compliant implementations, so this does not cause problems in normal BIP use.

* | | mac80211: make client powersave independent of interface typeMarco Porsch2012-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch prepares mac80211 for a later implementation of mesh or ad-hoc powersave clients. The structures related to powersave (buffer, TIM map, counters) are moved from the AP-specific interface structure to a generic structure that can be embedded into any interface type. The functions related to powersave are prepared to allow easy extension with different interface types. For example with: + } else if (sta->sdata->vif.type == NL80211_IFTYPE_MESH_POINT) { + ps = &sdata->u.mesh.ps; Some references to the AP's beacon structure are removed where they were obviously not used. The patch compiles without warning and has been briefly tested as AP interface with one client in PS mode.

* | | nl/cfg80211: force scan using an AP vif if requestedAntonio Quartulli2012-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the user wants to scan using a vif configured as AP, cfg80211 must give him a chance to do it, even if this will disrupt the stations performance due to off-channel scanning. To do so, this patch adds a 'force' flag to the SCAN_TRIGGER command which tells cfg80211 to perform the scanning operation even if the vif is an AP and the beaconing has already started.
