由 Rostislav Lisovy 提交于
This patch adds 802.11p OCB (Outside the Context of a BSS) mode support. When communicating in OCB mode a mandatory wildcard BSSID (48 '1' bits) is used. The EDCA parameters handling function was changed to support 802.11p specific values. The insertion of a newly discovered STAs is done in the similar way as in the IBSS mode -- through the deferred insertion. The OCB mode uses a periodic 'housekeeping task' for expiration of disconnected STAs (in the similar manner as in the MESH mode). New Kconfig option for verbose OCB debugging outputs is added.

When the new CONFIG_MAC80211_RC_MINSTREL_VHT is not set (default 'N'), there is no behavioral change including in sampling and MCS_GROUP_RATES remains 8. Otherwise MCS_GROUP_RATES is 10, and a module parameter *vht_only* (default 'true'), restricts the rates selection to VHT when VHT is supported. Regarding the debugfs stats buffer: It is explicitly increased from 8k to 32k to fit every rates incl. when both HT and VHT rates are enabled, as for the format, before: type rate tpt eprob *prob ret *ok(*cum) ok( cum) HT20/LGI ABCDP MCS0 0.0 0.0 0.0 1 0( 0) 0( 0) after: type rate tpt eprob *prob ret *ok(*cum) ok( cum) HT20/LGI ABCDP MCS0 0.0 0.0 0.0 1 0( 0) 0( 0) VHT40/LGI MCS5/2 0.0 0.0 0.0 0 0( 0) 0( 0) Signed-off-by: NKarl Beldan <karl.beldan@rivierawaves.com> Cc: Felix Fietkau <nbd@openwrt.org> Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Add routines to - maintain a PS mode for each peer and a non-peer PS mode - indicate own PS mode in transmitted frames - track neighbor STAs power modes - buffer frames when neighbors are in PS mode - add TIM and Awake Window IE to beacons - release frames in Mesh Peer Service Periods Add local_pm to sta_info to represent the link-specific power mode at this station towards the remote station. When a peer link is established, use the default power mode stored in mesh config. Update the PS status if the peering status of a neighbor changes. Maintain a mesh power mode for non-peer mesh STAs. Set the non-peer power mode to active mode during peering. Authenticated mesh peering is currently not working when either node is configured to be in power save mode. Indicate the current power mode in transmitted frames. Use QoS Nulls to indicate mesh power mode transitions. For performance reasons, calls to the function setting the frame flags are placed in HWMP routing routines, as there the STA pointer is already available. Add peer_pm to sta_info to represent the peer's link-specific power mode towards the local station. Add nonpeer_pm to represent the peer's power mode towards all non-peer stations. Track power modes based on received frames. Add the ps_data structure to ieee80211_if_mesh (for TIM map, PS neighbor counter and group-addressed frame buffer). Set WLAN_STA_PS flag for STA in PS mode to use the unicast frame buffering routines in the tx path. Update num_sta_ps to buffer and release group-addressed frames after DTIM beacons. Announce the awake window duration in beacons if in light or deep sleep mode towards any peer or non-peer. Create a TIM IE similarly to AP mode and add it to mesh beacons. Parse received Awake Window IEs and check TIM IEs for buffered frames. Release frames towards peers in mesh Peer Service Periods. Use the corresponding trigger frames and monitor the MPSP status. Append a QoS Null as trigger frame if neccessary to properly end the MPSP. Currently, in HT channels MPSPs behave imperfectly and show large delay spikes and frame losses.

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: NMarco Porsch <marco.porsch@s2005.tu-chemnitz.de> Signed-off-by: NPavel Zubarev <pavel.zubarev@gmail.com> Signed-off-by: NJavier Cardona <javier@cozybit.com> Signed-off-by: NJohn W.

The only thing that using crypto_blkcipher with ecb does over just using arc4 directly is wrapping the encrypt/decrypt function into a for loop, looping over each individual character.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack and drivers w/ no rate control algorithm. For drivers like RTL8187 that don't supply their own RC algorithms, this will cause ieee80211_register_hw to fail (making the driver unusable). This will tell kconfig to provide a warning if no rate control algorithms have been selected. That'll at least warn the user; users that know that their drivers supply a rate control algorithm can safely ignore the warning, and those who don't know (or who expect to be using multiple drivers) can select a default RC algorithm.

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: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>
