2012-06-28net: Use NLMSG_DEFAULT_SIZE in combination with nlmsg_new()Thomas Graf
Using NLMSG_GOODSIZE results in multiple pages being used as nlmsg_new() will automatically add the size of the netlink header to the payload thus exceeding the page limit. NLMSG_DEFAULT_SIZE takes this into account.

2012-06-20cfg80211: fix regression in multi-vif AP startFelix Fietkau
Commit "cfg80211: provide channel to start_ap function" assumes that the channel is always passed to the NL80211_CMD_START_AP command, however in case of multi-BSSID, hostapd only passes the channel for the first vif. This makes starting beaconing on secondary vifs fail with -EINVAL. Fix this by storing the channel provided to .start_ap in wdev->preset_chan and picking the first AP vif's channel for secondary vifs if not provided.

As defined in section 13.10.9.3 Case D (802.11-2012), this control variable is used to limit the mesh STA to send only one PREQ to a root mesh STA within this interval of time (in TUs). The default value for this variable is set to 2000 TUs.

The remain-on-channel time validation shouldn't depend on the value of HZ, as it does now with the check against jiffies, since then you might use a value that works on one system but not on another.

2012-06-05cfg80211: provide channel to join_mesh functionJohannes Berg
Just like the AP mode patch, instead of setting the channel and then joining the mesh network, provide the channel to join the network on to the join_mesh() function. Like in AP mode, you can also give the channel to the join-mesh nl80211 command now. Unlike AP mode, it picks a default channel if none was given. As libertas uses mesh mode interfaces but has no join_mesh callback and we can't simply break it, keep some compatibility code for that case and configure the channel directly for it. In the non-libertas case, where we store the channel until join, allow setting it while the interface is down. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2012-06-05cfg80211: disallow setting channel on WDS interfacesJohannes Berg
If it worked (Felix says it doesn't right now), the typical use-case for WDS interfaces would be to be slaved to AP mode interfaces. Therefore, it isn't necessary to set the channel on WDS interfaces. As they don't support powersave or anything like that, they also couldn't use a different channel anyway.

2012-06-05cfg80211: provide channel to start_ap functionJohannes Berg
Instead of setting the channel first and then starting the AP, let cfg80211 store the channel and provide it as one of the AP settings. This means that now you have to set the channel before you can start an AP interface, but since hostapd/wpa_supplicant always do that we're OK with this change. Alternatively, it's now possible to give the channel as an attribute to the start-ap nl80211 command, overriding any preset channel.

Fix merge between commit 3adadc08cc1e ("net ax25: Reorder ax25_exit to remove races") and commit 0ca7a4c87d27 ("net ax25: Simplify and cleanup the ax25 sysctl handling") The former moved around the sysctl register/unregister calls, the later simply removed them.

2012-04-16cfg80211: increse bss expire timeRajkumar Manoharan
The background scan completion takes more time when the station is having heavy uplink traffic. The scan state machine decides to fall back to home channel on every off-channel visit when there are pending frames in tx queue. bgscan completion took ~30sec on dual band US regulatory card. scan period = (20 active channels * probe timeout) + (12 passive channels * passive probe timeout) + (32 * timeout on home channel) + (32 * flush timeout) Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

2012-04-16cfg80211: enforce lack of interface combinationsJohannes Berg
My grand plan to allow drivers to gradually move over to advertising virtual interface combinations and only enforce with drivers that do want it enforced doesn't seem to be working out, only Christian ever added the advertising (to carl9170), nobody else did. Begin enforcing combinations in cfg80211 so that users can rely on the information reported about a device. Cc: "Luis R.
