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

2019-07-26T11:08:28+00:00

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.

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.

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.

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.

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

Plumb the new cfg80211 API for FTM responder statistics through to
the driver API in mac80211.

mac80211: Support adding duration for prepare_tx() callback

2018-05-23T09:06:10+00:00

There are specific cases, such as SAE authentication exchange, that
might require long duration to complete. For such cases, add support
for indicating to the driver the required duration of the prepare_tx()
operation, so the driver would still be able to complete the frame
exchange.

Currently, indicate the duration only for SAE authentication exchange,
as SAE authentication can take up to 2000 msec (as defined in IEEE
P802.11-REVmd D1.0 p. 3504).

As the patch modified the prepare_tx() callback API, also modify
the relevant code in iwlwifi.
