2012-04-09nl80211: ensure interface is up in various APIsJohannes Berg
The nl80211 handling code should ensure as much as it can that the interface is in a valid state, it can certainly ensure the interface is running. Not doing so can cause calls through mac80211 into the driver that result in warnings and unspecified behaviour in the driver.

Merge batch of fixes from Andrew Morton: "The simple_open() cleanup was held back while I wanted for laggards to merge things. I still need to send a few checkpoint/restore patches. I've been wobbly about merging them because I'm wobbly about the overall prospects for success of the project. But after speaking with Pavel at the LSF conference, it sounds like they're further toward completion than I feared - apparently davem is at the "has stopped complaining" stage regarding the net changes.

2012-04-05simple_open: automatically convert to simple_open()Stephen Boyd
Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-03-26cfg80211: allow CFG80211_SIGNAL_TYPE_UNSPEC in station_infoJohn W. Linville
The station_info struct had demanded dBm signal values, but the cfg80211 wireless extensions implementation was also accepting "unspecified" (i.e. RSSI) unit values while the nl80211 code was completely unaware of them.

2012-03-05cfg80211: Add an attribute to set inactivity timeout in AP modeVasanthakumar Thiagarajan
This patch adds an attribute, NL80211_ATTR_INACTIVITY_TIMEOUT, to set the inactivity timeout which can be used to remove the station in AP mode. This can be passed in NL80211_CMD_START_AP and used by the drivers which have AP MLME in firmware but don't support get_station() properly. To disable inactivity timer in userspace, wpa_s for example, there is a new flag, NL80211_FEATURE_INACTIVITY_TIMER, in nl80211_feature_flags through which drivers can register their capability to use the inactivity timeout to free the stations.

Mesh peer links are established only if average rssi of the peer candidate satisfies the threshold. This is not in 802.11s specification but was requested by David Fulgham, an open80211s user.

2012-02-06cfg80211: stop tracking authenticated stateJohannes Berg
To track authenticated state seems to have been a design mistake in cfg80211. It is possible to have out of band authentication (FT), tracking multiple authentications caused more problems than it ever helped, and the implementation in mac80211 is too complex. Remove all this complexity, and let userspace do whatever it wants to, mac80211 can deal with that just fine. Association is still tracked of course, but authentication no longer is. Local auth state changes are thus no longer of value, so ignore them completely. This will also help implement SAE -- asking the driver to do an authentication is now almost equivalent to sending an authentication frame, with the exception of shared key authentication which is still handled completely.

Following the tradition we have had with ath5k, ath9k, CRDA, wireless-regdb I'd like to license this code under the permissive ISC license for the code sharing purposes with other OSes, it'd sure be nice to help the landscape in this area. Although I am %82.89 owner of the regulatory code I have asked every contributor to the regulatory code and have receieved positive Acked-bys from everyone except two deceased entities: o Frans Pop RIP 2010 [0] - Frans Pop <elendil@planet.nl> - Frans Pop <fjp@debian.org> o Nokia RIP February, 11, 2011 [1], [2] - ext-yuri.ershov@nokia.com - kalle.valo@nokia.com Frans Pop's contribution was a simple patch 55f98938, titled, "wireless: remove trailing space in messages" which just add a \n to some printk lines. I'm going to treat these additions as uncopyrightable. As for the contributions made by employees on behalf of Nokia my contact point was Petri Karhula <petri.karhula@nokia.com> but after one month he noted he had not been able to get traction from the legal department on this request, as such it I proceeded by replacing their contributions in previous patches. The end goal is to help a clean rewrite that starts in userspace that is shared under ISC license which currently is taking place with the regulatory simulator [3].

2011-12-16cfg80211: allow following country IE power for custom regdom cardsLuis R. Rodriguez
By definition WIPHY_FLAG_STRICT_REGULATORY was intended to allow the wiphy to adjust itself to the country IE power information if the card had no regulatory data but we had no way to tell cfg80211 that if the card also had its own custom regulatory domain (these are typically custom world regulatory domains) that we want to follow the country IE's noted values for power for each channel. We add support for this and document it. This is not a critical fix but a performance optimization for cards with custom regulatory domains that associate to an AP with sends out country IEs with a higher EIRP than the one on the custom regulatory domain. In practice the only driver affected right now are the Atheros drivers as they are the only drivers using both WIPHY_FLAG_STRICT_REGULATORY and WIPHY_FLAG_CUSTOM_REGULATORY -- used on cards that have an Atheros world regulatory domain. Cards that have been programmed to follow a country specifically will not follow the country IE power. So although not a stable fix distributions should consider cherry picking this.

2011-12-13cfg80211: Fix race in bss timeoutVasanthakumar Thiagarajan
It is quite possible to run into a race in bss timeout where the drivers see the bss entry just before notifying cfg80211 of a roaming event but it got timed out by the time rdev->event_work got scehduled from cfg80211_wq. This would result in the following WARN-ON() along with the failure to notify the user space of the roaming. The other situation which is happening with ath6kl that runs into issue is when the driver reports roam to same AP event where the AP bss entry already got expired. To fix this, move cfg80211_get_bss() from __cfg80211_roamed() to cfg80211_roamed().

2011-12-07wireless: disable wext sysfs by defaultJohannes Berg
This code has been on the list to remove for a long time, so disable it by default, add a warning to its Kconfig, and schedule it for removal in 3.5. The only known dependency, hal, has not required it since its 0.5.12 release, which was in early 2009 and hal has since been deprecated completely.

2011-11-30cfg80211: amend regulatory NULL dereference fixLuis R. Rodriguez
Johannes' patch for "cfg80211: fix regulatory NULL dereference" broke user regulaotry hints and it did not address the fact that last_request was left populated even if the previous regulatory hint was stale due to the wiphy disappearing. Fix user reguluatory hints by only bailing out if for those regulatory hints where a request_wiphy is expected. The stale last_request considerations are addressed through the previous fixes on last_request where we reset the last_request to a static world regdom request upon reset_regdomains(). In this case though we further enhance the effect by simply restoring reguluatory settings completely. Cc: stable@vger.kernel.org Cc: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luis R.

2011-11-30cfg80211: fix race on init and driver registrationLuis R. Rodriguez
There is a theoretical race that if hit will trigger a crash. The race is between when we issue the first regulatory hint, regulatory_hint_core(), gets processed by the workqueue and between when the first device gets registered to the wireless core. This is not easy to reproduce but it was easy to do so through the regulatory simulator I have been working on. This is a port of the fix I implemented there [1].
