mac80211: disable mesh

2009-07-21T16:07:35+00:00

My kvm instance was complaining a lot about sleeping in atomic contexts in the mesh code, and it turns out that both mesh_path_add() and mpp_path_add() need to be able to sleep (they even use synchronize_rcu()!). I put in a might_sleep() to annotate that, but I see no way, at least right now, of actually making sure those functions are only called from process context since they are both called during TX and RX and the mesh code itself even calls them with rcu_read_lock() "held". Therefore, let's disable it completely for now. It's possible that I'm only seeing this because the hwsim's beaconing is broken and thus the peers aren't discovered right away, but it is possible that this happens even if beaconing is working, for a peer that doesn't exist or so. It should be possible to solve this by deferring the freeing of the tables to call_rcu() instead of using synchronize_rcu(), and also using atomic allocations, but maybe it makes more sense to rework the code to not call these from atomic contexts and defer more of the work to the workqueue. Right now, I can't work on either of those solutions though. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

cfg80211: fix Kconfig for users of cfg80211

2009-06-03T18:09:08+00:00

* iwm doesn't depend on cfg80211 or wireless extensions * rndis wlan selects cfg80211 - needs to depend * mac80211 selects cfg80211 - needs to depend Signed-off-by: Johannes Berg Acked-by: Randy Dunlap Signed-off-by: John W. Linville

mac80211: enable PS by default

2009-04-22T20:57:16+00:00

Enable PS by default (depending on Kconfig) -- rely on drivers to control the level using pm_qos. Due to the previous patch we turn off PS when necessary due to latency requirements. This has a Kconfig symbol so people can, if they really want, configure the default in their kernels. We may want to keep it at "default y" only in wireless-testing for a while.

MAC80211: Remove unused MAC80211_VERBOSE_SPECT_MGMT_DEBUG.

2009-04-20T20:36:26+00:00

Remove this unused Kconfig variable, which Intel apparently once promised to make use of but never did. Signed-off-by: Robert P. J. Day Acked-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: make Minstrel the default rate control algorithm

2008-11-26T14:47:03+00:00

This makes minstrel the default rate control algorithm for mac80211. For more information see: http://wireless.kernel.org/en/developers/Documentation/mac80211/RateControl/minstrel If someone can come up with a better algorithm they get a prize (undisclosed).

mac80211: remove debug frame dumping

2008-09-15T20:48:26+00:00

You can just pull up a monitor interface to get much more detailed information, or, when debugging a driver, insert dump code into the driver (which usually you will have to do anyway to dump the driver-specific information). Hence this option is useless. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: Reimplement WME using ->select_queue().

2008-07-18T02:21:12+00:00

The only behavior change is that we do not drop packets under any circumstances. If that is absolutely needed, we could easily add it back. With cleanups and help from Johannes Berg. Signed-off-by: David S. Miller

We will undo this after a few changsets. Signed-off-by: David S. Miller
