mac80211: handle channel frequency offset

2020-04-24T10:33:43+00:00

cfg80211_chan_def and ieee80211_channel recently gained a frequency offset component. Handle this where it makes sense (potentially required by S1G channels). For IBSS, TDLS, CSA, and ROC we return -EOPNOTSUPP if a channel with frequency offset is passed, since they may or may not work. Once someone tests and verifies these commands work on thos types of channels, we can remove that error. join_ocb and join_mesh look harmless because they use a simple ieee80211_vif_use_channel(), which is using an already verified channel, so we let those through.

ftrace: Rework event_create_dir()

2019-11-27T06:44:25+00:00

Rework event_create_dir() to use an array of static data instead of function pointers where possible. The problem is that it would call the function pointer on module load before parse_args(), possibly even before jump_labels were initialized. Luckily the generated functions don't use jump_labels but it still seems fragile. It also gets in the way of changing when we make the module map executable. The generated function are basically calling trace_define_field() with a bunch of static arguments. So instead of a function, capture these arguments in a static array, avoiding the function call. Now there are a number of cases where the fields are dynamic (syscall arguments, kprobes and uprobes), in which case a static array does not work, for these we preserve the function call. Luckily all these cases are not related to modules and so we can retain the function call for them. Also fix up all broken tracepoint definitions that now generate a compile error.

mac80211: pass the vif to cancel_remain_on_channel

This low level driver can find it useful to get the vif when a remain on channel session is cancelled. iwlwifi will need this soon. Signed-off-by: Emmanuel Grumbach Link: https://lore.kernel.org/r/20190723180001.5828-1-emmanuel.grumbach@intel.com Signed-off-by: Johannes Berg

mac80211: store tx power value from user to station

2019-04-26T11:02:11+00:00

This patch introduce a new driver callback drv_sta_set_txpwr. This API will copy the transmit power value passed from user space and call the driver callback to set the tx power for the station.

mac80211: notify driver on subsequent CSA beacons

2019-02-22T12:45:51+00:00

Some drivers may want to track further the CSA beacons, for example to compensate for buggy APs that change the beacon count or quiet mode during CSA flow. Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: abort CSA if beacon does not include CSA IEs

In case we receive a beacon without CSA IE while we are in the middle of channel switch - abort the operation. Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: allow drivers to use peer measurement API

2018-11-09T10:20:34+00:00

There's nothing much for mac80211 to do, so only pass through the requests with minimal checks and tracing. The driver must call cfg80211's results APIs. Signed-off-by: Johannes Berg

mac80211: tracing: avoid 'idx' variable

2018-11-09T10:11:36+00:00

This variable shadows something that gets generated inside the tracing macros, which causes sparse to warn. Avoid it so sparse output is more readable, even if it doesn't seem to cause any trouble. Signed-off-by: Johannes Berg

mac80211: support FTM responder configuration/statistics

2018-10-12T10:46:09+00:00

New bss param ftm_responder is used to notify the driver to enable fine timing request (FTM) responder role in AP mode. Plumb the new cfg80211 API for FTM responder statistics through to the driver API in mac80211.
