| * mac80211: allow reservation of a running chanctxLuciano Coelho2014-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With single-channel drivers, we need to be able to change a running chanctx if we want to use chanctx reservation. Not all drivers may be able to do this, so add a flag that indicates support for it. Changing a running chanctx can also be used as an optimization in multi-channel drivers when the context needs to be reserved for future usage. Introduce IEEE80211_CHANCTX_RESERVED chanctx mode to mark a channel as reserved so nobody else can use it (since we know it's going to change). In the future, we may allow several vifs to use the same reservation as long as they plan to use the chanctx on the same future channel.

| * mac80211: implement chanctx reservationLuciano Coelho2014-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support channel switch with multiple vifs and multiple contexts, we implement a concept of channel context reservation. This allows us to reserve a channel context to be used later. The reservation functionality is not tied directly to channel switch and may be used in other situations (eg. reserving a channel context during IBSS join). We first check if an existing compatible context exists and if it does, we reserve it. If there is no compatible context we create a new one and reserve it. Additionally, split ieee80211_vif_copy_chanctx_to_vlans() so we can call it while already holding the chanctx mutex.

| * mac80211: refactor ieee80211_assign/unassign_vif_chanctx into oneLuciano Coelho2014-04-09
| | | | | | | | | | | | | | | | | | | | | | Combine the functions into one, so that we can switch from one context to the other without having to unassign and assign separately. This is needed by the channel reservation functionality because otherwise we have a small period of time when the chanctx is set to NULL, which can cause problems if someone else is trying to dereference it.

| * mac80211: split ieee80211_vif_change_channel in twoLuciano Coelho2014-04-09
| | | | | | | | | | | | | | | | | | | | ieee80211_vif_change_channel() locks chanctx_mtx. When implementing channel reservation for CS, we will need to call the function to change channel when the lock is already held, so split the part that requires the lock out and leave the locking in the original function.

| * mac80211: protect AP VLAN list with local->mtxMichal Kazior2014-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was impossible to change chanctx of master AP for AP VLANs because the copy function requires RTNL which can't be simply taken in mac80211 code due to possible deadlocks. This is required for future chanctx reservation that re-bind vifs to new chanctx. This requires safe AP VLAN iteration without RTNL. Now VLANs can be iterated while holding either RTNL or local->mtx because the list is modified while holding both of these locks.

| * cfg80211/mac80211: move more combination checks to mac80211Luciano Coelho2014-04-09

With this patch all interface combination checks are now out of cfg80211 (except for the channel switch case which will be addressed in a future commit). Additionally, modify the ieee80211_check_combinations() function so that an undefined chandef can be passed, in order to use it before a channel is defined.

| * cfg80211: Enable GO operation on additional channelsIlan Peer2014-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow GO operation on a channel marked with IEEE80211_CHAN_GO_CONCURRENT iff there is an active station interface that is associated to an AP operating on the same channel in the 2 GHz band or the same UNII band (in the 5 GHz band). This relaxation is not allowed if the channel is marked with IEEE80211_CHAN_RADAR. Note that this is a permissive approach to the FCC definitions, that require a clear assessment that the device operating the AP is an authorized master, i.e., with radar detection and DFS capabilities. It is assumed that such restrictions are enforced by user space. Furthermore, it is assumed, that if the conditions that allowed for the operation of the GO on such a channel change, i.e., the station interface disconnected from the AP, it is the responsibility of user space to evacuate the GO from the channel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If chandef had non-HT width it was possible for radar_enabled update to not be propagated properly through drv_config(). This happened because ieee80211_hw_conf_chan() would never see different local->hw.conf.chandef and local->_oper_chandef. This wasn't a problem with HT chandefs because _oper_chandef width is reset to non-HT in ieee80211_free_chanctx() making ieee80211_hw_conf_chan() to kick in. This problem led (at least) ath10k to not start CAC if prior CAC was cancelled and both CACs were requested for identical non-HT chandefs.

* | mac80211: fix software remain-on-channel implementationJohannes Berg2014-04-09
|/ | | | | | | | | | | | | | | | | | | Jouni reported that when doing off-channel transmissions mixed with on-channel transmissions, the on-channel ones ended up on the off-channel in some cases. The reason for that is that during the refactoring of the off- channel code, I lost the part that stopped all activity and as a consequence the on-channel frames (including data frames) were no longer queued but would be transmitted on the temporary channel. Fix this by simply restoring the lost activity stop call.

This means that we can hear beacons or probe responses from adjacent channels. These frames will have a significant lower RSSI which will feed all kinds of logic with inaccurate data. An obvious example is the roaming algorithm that will think our AP is getting weak and will try to move to another AP. In order to avoid this, update the signal only if the frame has been heard on the same channel as the one advertised by the AP in its DS / HT IEs. We refrain from updating the values only if the AP is already in the BSS list so that we will still have a valid (but inaccurate) value if the AP was heard on an adjacent channel only. To achieve this, stop taking the channel from DS / HT IEs in mac80211. The DS / HT IEs is taken into account to discard the frame if it was received on a disabled channel. This can happen due to the same phenomenon: the frame is sent on channel 12, but heard on channel 11 while channel 12 can be disabled on certain devices. Since this check is done in cfg80211, stop even checking this in mac80211.

No driver ever used it, so that was fine. Now I'm adding support for NAPI to our driver, so add some code to mac80211 again to support NAPI. John was originally wrapping some (but not nearly all NAPI-related functions), but that doesn't scale very well with the number of functions that are there, some of which are even only inlines. Thus, instead of doing that, let the drivers manage the NAPI struct, except for napi_add() which is needed so mac80211 knows how to call napi_gro_receive(). Also remove some no longer needed definitions that were left when NAPI support was removed.

If we already got an ack, there's no reason to continue disconnecting. this can help devices that supports IEEE80211_HW_CONNECTION_MONITOR only partially (e.g. take care of keep alives, but does not probe the ap. In case the device wants to disconnect without probing, it can just call ieee80211_connection_loss.
