wifi: cfg80211: add regulatory flag to allow VLP AP operation

2024-06-12T11:04:25+00:00

Add a regulatory flag to allow VLP AP operation even on
channels otherwise marked NO_IR, which may be possible
in some regulatory domains/countries.

Note that this requires checking also when the beacon is
changed, since that may change the regulatory power type.

wifi: cfg80211: add tracing for wiphy work

2024-05-23T08:21:22+00:00

Add trace events to trace when wiphy works are queued (or
delayed ones scheduled), and other APIs are called. Also
add an event when the worker starts, before acquiring the
mutex, to be able to see potential delays due to locking.

wifi: cfg80211: sort trace events again

2024-05-23T08:21:20+00:00

They were meant to be split into ops and APIs, but some
ops were added in the wrong place. Fix that.

tracing/treewide: Remove second parameter of __assign_str()

2024-05-23T00:14:47+00:00

With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.

This means that with:

  __string(field, mystring)

Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.

There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:

  git grep -l __assign_str | while read a ; do
      sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
      mv /tmp/test-file $a;
  done

I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.

Note, the same updates will need to be done for:

  __assign_str_len()
  __assign_rel_str()
  __assign_rel_str_len()

I tested this with both an allmodconfig and an allyesconfig (build only for both).

wifi: cfg80211: handle color change per link

2024-05-03T08:18:03+00:00

Currently, during color change, no link id information is passed down.
In order to support color change during Multi Link Operation, it is
required to pass link id as well.
Additionally, update notification APIs to allow drivers/mac80211 to
pass the link ID.

wifi: cfg80211: print flags in tracing in hex

2024-03-04T13:31:14+00:00

It's confusing to see decimal, e.g. 20, here. Printing
the flags in hex (0x14 == 20) is much clearer.

wifi: cfg80211: add support for link id attribute in NL80211_CMD_DEL_STATION

2024-02-12T20:11:24+00:00

Currently whenever NL80211_CMD_DEL_STATION command is called without any
MAC address, all stations present on that interface are flushed.
However with MLO there is a need to flush such stations only which are
using at least a particular link from the AP MLD interface.

For example - 2 GHz and 5 GHz are part of an AP MLD.
To this interface, following stations are connected -
   1. One non-EHT STA on 2 GHz link.
   2. One non-EHT STA on 5 GHz link.
   3. One Multi-Link STA having 2 GHz and 5 GHz as active links.

Now if currently, NL80211_CMD_DEL_STATION is issued by the 2 GHz link
without any MAC address, it would flush all station entries. However,
flushing of station entry #2 at least is not desireable since it
is connected to 5 GHz link alone.

Hence, add an option to pass link ID as well in the command so that if link
ID is passed, stations using that passed link ID alone would be flushed
and others will not.

So after this, station entries #1 and #3 alone would be flushed and #2 will
remain as it is.
