[v3,00/11] wifi: cfg80211/mac80211: improve support for multiple radios

Message

Felix Fietkau Oct. 4, 2024, 8:21 p.m. UTC

This series adds support for restricting vifs to a set of radios.
The allowed radios mask is used to restrict scanning, off-channel activity,
and can be used by the driver to selectively enable monitoring and manage
radio state.
It also adds support for monitoring on multiple channels at the same time.

Changes since RFC:
 - split cfg80211 and mac80211 changes
 - remove mac80211 per-radio tracking for monitor state
 - remove per-radio start/stop calls
 - remove radio index from rx status
 - rewrite multi-channel monitor support

Changes since PATCH:
 - fix commit commit descriptions regarding remain-on-channel
 - fix return code in ibss scan change
 - fix wdev->radio_mask initialization

Changes since PATCH v2:
 - fix build error with tracing on .set_monitor_channel change

Felix Fietkau (11):
  wifi: cfg80211: add option for vif allowed radios
  wifi: mac80211: use vif radio mask to limit ibss scan frequencies
  wifi: mac80211: use vif radio mask to limit creating chanctx
  wifi: cfg80211: report per wiphy radio antenna mask
  wifi: mac80211: remove status->ampdu_delimiter_crc
  wifi: cfg80211: pass net_device to .set_monitor_channel
  wifi: mac80211: add flag to opt out of virtual monitor support
  wifi: cfg80211: add monitor SKIP_TX flag
  wifi: mac80211: add support for the monitor SKIP_TX flag
  wifi: mac80211: refactor ieee80211_rx_monitor
  wifi: mac80211: filter on monitor interfaces based on configured channel
