When transmitting a frame, the transmitter waits a random number of slots between 0 and cw. Thus, the contention time is (cw / 2) * t_slot which we can represent instead as (cw * t_slot) >> 1. Also fix a few other accounting bugs around contention time, and add comments. Signed-off-by:

Multiple virtual AP interfaces can currently try to use different beacon intervals, but that just leads to problems since it won't actually be done that way by drivers. Return an error in this case to make sure it won't be done wrong. Also, ignore attempts to change the DTIM period or beacon interval during the lifetime of the BSS. Signed-off-by:

Introduce NL80211_ATTR_SCHED_SCAN_INTERVAL as a required attribute for NL80211_CMD_START_SCHED_SCAN. This value informs the driver at which intervals the scheduled scan cycles should be executed. Signed-off-by:

Implement support for HW scheduled scan. The mac80211 code doesn't perform scheduled scans itself, but calls the driver to start and stop scheduled scans. This patch also creates a trace event class to be used by drv_hw_scan and the new drv_sched_scan_start and drv_sched_stop functions, in order to avoid duplicate code. Signed-off-by:

Implement new functionality for scheduled scan offload. With this feature we can scan automatically at certain intervals. The idea is that the hardware can perform scan automatically and filter on desired results without waking up the host unnecessarily. Add NL80211_CMD_START_SCHED_SCAN and NL80211_CMD_STOP_SCHED_SCAN commands to the nl80211 interface. When results are available they are reported by NL80211_CMD_SCHED_SCAN_RESULTS events. The userspace is informed when the scheduled scan has stopped with a NL80211_CMD_SCHED_SCAN_STOPPED event, which can be triggered either by the driver or by a call to NL80211_CMD_STOP_SCHED_SCAN.

The functions drv_add_interface() and drv_remove_interface() print out the same values in the traces. Combine the traces of these two functions into one event class to remove some duplicate code. Also add a new class for functions drv_set_frag_threshold() and drv_set_rts_threshold(). Cc: Johannes Berg <johannes@sipsolutions.net> Signed-off-by:

Not sure if I'm chasing a ghost here, seems like the mesh_path->size_order needs to be inside an RCU-read section to prevent that value from changing between table allocation and copying. We have observed crashes that might be caused by this. Signed-off-by:

Mesh beacons no longer use all-zeroes BSSID. Beacon frames for MBSS, infrastructure BSS, or IBSS are differentiated by the Capability Information field in the Beacon frame. A mesh STA sets the ESS and IBSS subfields to 0 in transmitted Beacon or Probe Response management frames. Signed-off-by:

Introduce a new configuration option to support AMPE from userspace. Prior to this series we only supported authentication in userspace: an authentication daemon would authenticate peer candidates in userspace and hand them over to the kernel. From that point the mesh stack would take over and establish a peer link (Mesh Peering Management). These patches introduce support for Authenticated Mesh Peering Exchange in userspace. The userspace daemon implements the AMPE protocol and on successfull completion create mesh peers and install encryption keys. Signed-off-by:

In case of pre v2.1 devices authentication request will return success immediately if the link key already exists without any authentication process. That means, it's not possible to re-authenticate the link if you already have combination key and for instance want to re-authenticate to get the high security (use 16 digit pin). Therefore, it's necessary to check security requirements on auth complete event to prevent not enough secure connection. Signed-off-by:
