cfg80211

Regulatory

Issues

  • make scan timeout variable depending on scan length, in case scans take longer than the current 15 seconds

mac80211

Mesh

  • If a mesh join request does not come with a frequency, initiate scan for suitable neighbor MBSS frequency first.

AP support

Issues

  • drivers with IV offload do not correctly report IV/PN to nl80211
  • Need to stop TX/RX when a radar is detected for the duration of scan for a new channel.

Improvements

  • reset the connection and beacon monitor timers when we are able to successfully TX data to an AP (we currently do it on RX)
  • move survey caching code from ath9k to mac80211 so that other drivers can simply update channel survey data once and all cached data can be sent back to userspace as ath9k does it
  • improve roaming time by collapsing synchronize_rcu() (or even getting rid of it by using call_rcu()) in station/key management

power saving

  • move checking for broadcast / multicast frames to mac80211 before going to PS. ath9k already has some code for this, this should be moved to mac80211. Or just extend documentation to indicate drivers are required to do this.
  • 11v support (eventually)
  • implement a PS library, a la described in http://marc.info/?l=linux-wireless&m=135838252227053

Offchannel work

  • optimise "offchannel" to not stop beaconing/traffic/etc. when using the operating channel
  • implement addBA in terms off "offchannel" on the operating channel so it blocks other offchannel while waiting for a response
  • don't time out RX BA agreements while offchannel
  • do TX flushing as appropriate
  • Wait for DTIM beacon and multicast traffic before going offchannel

drivers

testing

  • client powersave testing

  • q/a procedure for stack
  • winlab
  • info on test coverage
  • tests themselves need to be documented
  • instructions how to run tests

wireless.kernel.org site

  • fix CSS colours, for example link colours (if you want to start, look at the files in moin/linuxwireless/css/ and send diffs to <johannes AT sipsolutions DOT net>)

  • fix print view to include a black&white logo
