cfg80211: make RATE_INFO_BW_20 the default

2018-04-13T17:47:49+00:00

[ Upstream commit 842be75c77cb72ee546a2b19da9c285fb3ded660 ]

Due to the way I did the RX bitrate conversions in mac80211 with
spatch, going setting flags to setting the value, many drivers now
don't set the bandwidth value for 20 MHz, since with the flags it
wasn't necessary to (there was no 20 MHz flag, only the others.)

Rather than go through and try to fix up all the drivers, instead
renumber the enum so that 20 MHz, which is the typical bandwidth,
actually has the value 0, making those drivers all work again.

If VHT was hit used with a driver not reporting it, e.g. iwlmvm,
this manifested in hitting the bandwidth warning in
cfg80211_calculate_bitrate_vht().

cfg80211/mac80211: fix BSS leaks when abandoning assoc attempts

2017-01-09T07:32:17+00:00

commit e6f462df9acd2a3295e5d34eb29e2823220cf129 upstream.

When mac80211 abandons an association attempt, it may free
all the data structures, but inform cfg80211 and userspace
about it only by sending the deauth frame it received, in
which case cfg80211 has no link to the BSS struct that was
used and will not cfg80211_unhold_bss() it.

Fix this by providing a way to inform cfg80211 of this with
the BSS entry passed, so that it can clean up properly, and
use this ability in the appropriate places in mac80211.

This isn't ideal: some code is more or less duplicated and
tracing is missing. However, it's a fairly small change and
it's thus easier to backport - cleanups can come later.

cfg80211: add ability to check DA/SA in A-MSDU decapsulation

2016-10-12T07:19:10+00:00

We should not accept arbitrary DA/SA inside A-MSDUs, it could be used
to circumvent protections, like allowing a station to send frames and
make them seem to come from somewhere else.

Add the necessary infrastructure in cfg80211 to allow such checks, in
further patches we'll start using them.

cfg80211: let ieee80211_amsdu_to_8023s() take only header-less SKB

2016-10-12T07:19:10+00:00

There's only a single case where has_80211_header is passed as true,
which is in mac80211. Given that there's only simple code that needs
to be done before calling it, export that function from cfg80211
instead and let mac80211 call it itself.

docs-rst: sphinxify 802.11 documentation

2016-10-11T22:19:17+00:00

This is just a very basic conversion, I've split up the original
multi-book template, and also split up the multi-part mac80211
part in the original book; neither of those were handled by the
automatic pandoc conversion.

Fix errors that showed up, resulting in a much nicer rendering,
at least for the interface combinations documentation.

cfg80211: Provide an API to report NAN function termination

Provide a function that reports NAN DE function termination. The function
may be terminated due to one of the following reasons: user request,
ttl expiration or failure.
