Merge branch 'mac80211' into mac80211-next

2015-07-17T13:39:41+00:00

This is necessary to merge the new TDLS and mesh patches, as they depend on some fixes. Signed-off-by: Johannes Berg

cfg80211: allow mgmt_frame_register callback to sleep

2015-07-17T13:38:26+00:00

This callback is currently not allowed to sleep, which makes it more difficult to implement proper driver methods in mac80211 than it has to be. Instead of doing asynchronous work here in mac80211, make it possible for the callback to sleep by doing some asynchronous work in cfg80211. This also enables improvements to other drivers, like ath6kl, that would like to sleep in this callback. While at it, also fix the code to call the driver on the implicit unregistration when an interface is removed, and do that also when a P2P-Device wdev is destroyed (otherwise we leak the structs.)

cfg80211: use RTNL locked reg_can_beacon for IR-relaxation

2015-07-17T13:02:02+00:00

The RTNL is required to check for IR-relaxation conditions that allow more channels to beacon. Export an RTNL locked version of reg_can_beacon and use it where possible in AP/STA interface type flows, where IR-relaxation may be applicable.

cfg80211: properly send NL80211_ATTR_DISCONNECTED_BY_AP in disconnect

2015-05-26T13:21:27+00:00

When we disconnect from the AP, drivers call cfg80211_disconnect(). This doesn't know whether the disconnection was initiated locally or by the AP though, which can cause problems with the supplicant, for example with WPS. This issue obviously doesn't show up with any mac80211 based driver since mac80211 doesn't call this function. Fix this by requiring drivers to indicate whether the disconnect is locally generated or not. I've tried to update the drivers, but may not have gotten the values correct, and some drivers may currently not be able to report correct values. In case of doubt I left it at false, which is the current behaviour. For libertas, make adjustments as indicated by Dan Williams.

cfg80211: change GO_CONCURRENT to IR_CONCURRENT for STA

2015-05-06T13:50:02+00:00

The GO_CONCURRENT regulatory definition can be extended to station interfaces requesting to IR as part of TDLS off-channel operations. Rename the GO_CONCURRENT flag to IR_CONCURRENT and allow the added use-case. Change internal users of GO_CONCURRENT to use the new definition.

cfg80211: move IE split utilities here from mac80211

2015-04-07T11:56:41+00:00

As the next patch will require the IE splitting utility functions in cfg80211, move them there from mac80211. Signed-off-by: Johannes Berg

2015-03-31T20:39:04+00:00

Johannes Berg says: ==================== Lots of updates for net-next; along with the usual flurry of small fixes, cleanups and internal features we have: * VHT support for TDLS and IBSS (conditional on drivers though) * first TX performance improvements (the biggest will come later) * many suspend/resume (race) fixes * name_assign_type support from Tom Gundersen ==================== Signed-off-by: David S.

cfg80211: pass name_assign_type to rdev_add_virtual_intf()

2015-03-30T08:36:17+00:00

This will expose in /sys whether the ifname of a device is set by userspace or generated by the kernel. The latter kind (wlanX, etc) is not deterministic, so userspace needs to rename these devices to names that are guaranteed to stay the same between reboots. The former, however should never be renamed, so userspace needs to be able to reliably tell the difference.

cfg/mac80211: add regulatory classes IE during TDLS setup

2015-03-30T08:26:36+00:00

Seems Broadcom TDLS peers (Nexus 5, Xperia Z3) refuse to allow TDLS connection when channel-switching is supported but the regulatory classes IE is missing from the setup request. Add a chandef to reg-class translation function to cfg80211 and use it to add the required IE during setup. For now add only the current regulatory class as supported - it is enough to resolve the compatibility issue.

net: Introduce possible_net_t

2015-03-12T18:39:40+00:00

Having to say > #ifdef CONFIG_NET_NS > struct net *net; > #endif in structures is a little bit wordy and a little bit error prone. Instead it is possible to say: > typedef struct { > #ifdef CONFIG_NET_NS > struct net *net; > #endif > } possible_net_t; And then in a header say: > possible_net_t net; Which is cleaner and easier to use and easier to test, as the possible_net_t is always there no matter what the compile options. Further this allows read_pnet and write_pnet to be functions in all cases which is better at catching typos. This change adds possible_net_t, updates the definitions of read_pnet and write_pnet, updates optional struct net * variables that write_pnet uses on to have the type possible_net_t, and finally fixes up the b0rked users of read_pnet and write_pnet.
