| | | | | | | | | | | | | The Peer-to-Peer IE is vendor-specific IE identified by WiFi Alliance OUI and specific P2P OUI type. The payload of this IE consists of so-called P2P attributes. This patch adds definitions for processing these attributes.

* mac80211: Implement mesh synchronization frameworkJavier Cardona2012-04-101-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds MBSS extensible synchronization framework (Sec. 13.13.2 of IEEE Std. 802.11-2012). The framework is implemented via an ops table which defines the following functions: rx_bcn_presp() - this is called every time a mesh beacon is received. adjust_tbtt() - this is called immediately before a beacon is about to be transmitted. The default neighbor offset synchronization defined in the standard is implemented. We also provide template functions for vendor specific methods. When neighbor offset synchronization is active (which is the default) mesh neighbors in the same MBSS will track timing offsets to each other and compensate clock drift. In our tests we observed that this mesh synchronization implementation successfully corrected drifts between stations of ~2PPM while introducing a jitter of ~20us. It is also possible to test this framework on mac80211_hwsim simulated phys to see how it behaves under different topologies, over poor links, etc. Signed-off-by: Marco Porsch <marco.porsch@s2005.tu-chemnitz.de> Signed-off-by: Pavel Zubarev <pavel.zubarev@gmail.com> Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | Arik's patch "mac80211: allow action frames with unknown BSSID in GO mode" allowed any action frames in P2P mode to go through, but only to cooked monitor interfaces as the IEEE80211_RX_RA_MATCH was still cleared. As a result my no-monitor patches broke invitation responses. Instead of allowing any action frames in P2P GO mode to go through with a wrong BSSID like that patch did, allow all public action frames. They will never be processed by mac80211, but can be reported via nl80211 then. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | Register and implement the TDLS cfg80211 callback functions. Internally prepare and send TDLS management frames. We incorporate local STA capabilities and supported rates with extra IEs given by usermode. The resulting packet is either encapsulated in a data frame, or assembled as an action frame. It is transmitted either directly or through the AP, as mandated by the TDLS specification. Declare support for the TDLS external setup wiphy capability. This tells usermode to handle link setup and discovery on its own, and use the kernel driver for sending TDLS mgmt packets.

| | | | | | | | | | | | | | | | | | | The Mesh Control header only includes 0, 1 or 2 addresses. If there is one address, it should be interpreted as Address 4. If there are 2, they are interpreted as Addresses 5 and 6 (Address 4 being the 4th address in the 802.11 header). The address extension used to hold up to 3 addresses instead of the current 2. I'm not sure which draft version changed this, but it is very unlikely that it will change again given the state of the approval process of this draft. See section 7.1.3.6.3 in current draft (8.0). Also, note that the extra address that I'm removing was not being used, so this change has no effect on over-the-air frame formats.

| | | | | | | | | | | | | | | | | | | | | This patch updates IEEE802.11 mesh constants to be consistent with newly approved values. It modifies some values, as well as adds many new constants in preparation for updating mesh code to the current 802.11s drafts. ANA numbers were taken from: https://mentor.ieee.org/802.11/dcn/09/11-09-0031-12-0000-ana-database-assigned-number-authority.xls A few notes are in order: 1. This will break backwards compatibility with existing Linux kernels as over-the-air constants have changed. 2. Some old and obsolete constants have been retained for now as the mesh code itself hasn't been updated yet to the new 802.11s draft. This was desired to keep the existing mesh scheme working until it can be updated. Adding the approved values is the first step in updating the mesh code. 3. Obsolete constants have been clearly marked. 4. All ANA approved 802.11s constants have been added. Signed-off-by: Steve deRosier <steve@cozybit.com> Signed-off-by: John W.

* mac80211: clean up/fix aggregation codeJohannes Berg2010-04-071-1/+0
| | | | | | | | | | | | | | | | | | | | | | | The aggregation code has a number of quirks, like inventing an unneeded WLAN_BACK_TIMER value and leaking memory under certain circumstances during station destruction. Fix these issues by using the regular aggregation session teardown code and blocking new aggregation sessions, all before the station is really destructed. As a side effect, this gets rid of the long code block to destroy aggregation safely. Additionally, rename tid_state_rx which can only have the values IDLE and OPERATIONAL to tid_active_rx to make it easier to understand that there is no bitwise stuff going on on the RX side -- the TX side remains because it needs to keep track of the driver and peer states.
