| * | cfg80211: process pending events when unregistering net deviceDaniel Drake2012-08-06
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libertas currently calls cfg80211_disconnected() when it is being brought down. This causes an event to be allocated, but since the wdev is already removed from the rdev by the time that the event processing work executes, the event is never processed or freed. http://article.gmane.org/gmane.linux.kernel.wireless.general/95666 Fix this leak, and other possible situations, by processing the event queue when a device is being unregistered.

| | | | | | | | | | | | | | | | | | | | Restore the default state to the "beacon_found" flag when the channel flags are restored. Otherwise, we can end up with a channel that we can no longer transmit on even when we can see beacons on that channel.

| * cfg80211: add channel flag to prohibit OFDM operationSeth Forshee2012-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the only way for wireless drivers to tell whether or not OFDM is allowed on the current channel is to check the regulatory information. However, this requires hodling cfg80211_mutex, which is not visible to the drivers. Other regulatory restrictions are provided as flags in the channel definition, so let's do similarly with OFDM. This patch adds a new flag, IEEE80211_CHAN_NO_OFDM, to tell drivers that OFDM on a channel is not allowed. This flag is set on any channels for which regulatory indicates that OFDM is prohibited.

That broke rt2x00 (and perhaps some other drivers) that do not set chan->max_power. It is not so easy to fix this problem correctly in rt2x00. According to commit eccc068e8 changelog, change claim only to save maximum regulatory power - changing setting of chan->max_power was side effect. This patch restore previous calculations of chan->max_power and do not touch chan->max_reg_power.

This abstraction will also be useful to support offloading P2P operations to the device, e.g. periodic listen for discoverability. Currently, the driver is responsible for assigning a MAC address to the P2P Device, but this could be changed by allowing a MAC address to be given to the NEW_INTERFACE command. As it has no associated netdev, a P2P Device can only be identified by its wdev identifier but the previous patches allowed using the wdev identifier in various APIs, e.g. remain-on-channel.

This can be done for example on a cell phone. To enable these hints we simply allow them through as user regulatory hints but we allow userspace to clasify the hint as either coming directly from the user or coming from a cellular base station. This option is only available when you enable CONFIG_CFG80211_CERTIFICATION_ONUS.

This option is also usable for researchers and experimenters looking to add code in the kernel without impacting compliant code. We'd use CONFIG_EXPERT alone but it seems that most standard Linux distributions are enabling CONFIG_EXPERT already. This allows us to define 802.11 specific kernel features under a flag that is intended by design to be disabled by standard Linux distributions, and only enabled by system integrators or distributions that have done work to ensure regulatory certification on the system with the enabled features.

| * | cfg80211: fix set_regdom() to cancel requests with same alpha2Kalle Valo2012-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While adding regulatory support to ath6kl I noticed that I easily got the regulatory code confused. The way to reproduce the bug was: 1. iw reg set FI (in userspace) 2. cfg80211 calls ath6kl_reg_notify(FI) 3. ath6kl sets regdomain in firmware 4. firmware sends regdomain event to notify about the new regdomain (FI) 5. ath6kl calls regulatory_hint(FI) And this (from FI to FI transition) confuses cfg80211 and after that I only get "Pending regulatory request, waiting for it to be processed...." messages and regdomain changes won't work anymore. The reason why ath6kl calls regulatory_hint() is that firmware can change the regulatory domain by it's own, for example due to 11d IEs. I could of course workaround this in ath6kl but I think it's better to handle the case in cfg80211. The fix is pretty simple, use a different error code if the regdomain is same and then just set the request processed so that it doesn't block new requests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert commit b78e8ceac23655e1e06b30aa95ab11742d1ac7c0 ("cfg80211: track monitor channel") and remove the set_monitor_enabled() callback. Due to the tracking happening in NETDEV_PRE_UP, it had introduced bugs because the monitor interface callback would be called before the device was started. It looks like there's no way to fix this, and using NETDEV_PRE_UP is broken anyway (since there's no NETDEV_UP_FAIL), so remove all that code, track interfaces in NETDEV_UP and also stop tracking the monitor channel in cfg80211. This mostly reverts to before the tracking, except that we keep the interface count tracking so that setting the monitor channel can be rejected properly.
