There's little point in this config symbol, if
tracing is disabled the overhead is negligible
and if you think it's too bad you can always
turn off tracing completely.Also remove the part where we don't have sparse
check the tracing code -- it seems that it can
now deal with it (or the code changed).Signed-off-by: Johannes Berg

Register and implement the TDLS cfg80211 callback functions.
Internally prepare and send TDLS management frames. We incorporate
local STA capabilities and supported rates with extra IEs given by
usermode. The resulting packet is either encapsulated in a data frame,
or assembled as an action frame. It is transmitted either directly or
through the AP, as mandated by the TDLS specification.Declare support for the TDLS external setup wiphy capability. This
tells usermode to handle link setup and discovery on its own, and use the
kernel driver for sending TDLS mgmt packets.Signed-off-by: Arik Nemtsov

The only thing that using crypto_blkcipher with ecb does over just using
arc4 directly is wrapping the encrypt/decrypt function into a for loop,
looping over each individual character.
To be able to do this, it pulls in around 40 kb worth of unnecessary
kernel modules (at least on a MIPS embedded device).
Using arc4 directly not only eliminates those dependencies, it also makes
the code smaller.Signed-off-by: Felix Fietkau

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.Reviewed-by: Ingo Molnar

Extend nl80211 to report an exponential weighted moving average (EWMA) of the
signal value. Since the signal value usually fluctuates between different
packets, an average can be more useful than the value of the last packet.This uses the recently added generic EWMA library function.

It's not useful to build LED triggers when there's no LEDs that can be
triggered by them. Therefore, fix up the dependencies so that this
cannot happen, and fix a few users that select triggers to depend on
LEDS_CLASS as well (there is also one user that also selects LEDS_CLASS,
which is OK).Signed-off-by: Johannes Berg

Allow selection of minstrel_ht as default rate control algorithm. At
the moment minstrel_ht can only be requested by the driver code but
not selected as default in make menuconfig. Fix this by using
minstrel_ht when minstrel was selected as default and minstrel_ht
is available.This change won't affect legacy devices as minstrel_ht falls back to
minstrel in that case.Signed-off-by: Helmut Schaa

Enhance tracing by adding tracing for a variety of
callbacks that the drivers call, and also for
internal calls (currently limited to queue status).
This can aid debugging what is going on in mac80211
in interaction with drivers, since we can now see
what drivers call and not just what mac80211 calls
in the driver.Signed-off-by: Johannes Berg

I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack
and drivers w/ no rate control algorithm. For drivers like RTL8187 that don't
supply their own RC algorithms, this will cause ieee80211_register_hw to
fail (making the driver unusable).This will tell kconfig to provide a warning if no rate control algorithms
have been selected. That'll at least warn the user; users that know that
their drivers supply a rate control algorithm can safely ignore the
warning, and those who don't know (or who expect to be using multiple
drivers) can select a default RC algorithm.Signed-off-by: Andres Salomon

The payload alignment warning enabled by MAC80211_DEBUG_PACKET_ALIGNMENT is
difficult. To fix it, a firmware change is needed but in most cases that's
very difficult. So the benefit from the warning is low and most probably
it just creates more confusion for people who just enable all warnings
(like it did for me).Remove the unaligned IP payload warning and the kconfig option. But
leave the unaligned packet warning, it will be enabled with

Finally! This is what you've all been waiting for!
This patch makes cfg80211 take care of wext emulation
_completely_ by itself, drivers that don't need things
cfg80211 doesn't do yet don't even need to be aware of
wireless extensions.
This means we can also clean up mac80211's and iwm's
Kconfig and make it possible to build them w/o wext
now!RIP wext.

My kvm instance was complaining a lot about sleeping
in atomic contexts in the mesh code, and it turns out
that both mesh_path_add() and mpp_path_add() need to
be able to sleep (they even use synchronize_rcu()!).
I put in a might_sleep() to annotate that, but I see
no way, at least right now, of actually making sure
those functions are only called from process context
since they are both called during TX and RX and the
mesh code itself even calls them with rcu_read_lock()
"held".Therefore, let's disable it completely for now.
It's possible that I'm only seeing this because the
hwsim's beaconing is broken and thus the peers aren't
discovered right away, but it is possible that this
happens even if beaconing is working, for a peer that
doesn't exist or so.It should be possible to solve this by deferring the
freeing of the tables to call_rcu() instead of using
synchronize_rcu(), and also using atomic allocations,
but maybe it makes more sense to rework the code to
not call these from atomic contexts and defer more of
the work to the workqueue. Right now, I can't work on
either of those solutions though.Signed-off-by: Johannes Berg

The old infrastructure was:
- the default algorithm is built into mac80211
- other algorithms get into their own modulesThe implementation of this complicated scheme was horrible
(just look at net/mac80211/Makefile), and anyone adding a new
algorithm would most likely not get it right at his first attempt.This patch therefore builds all enabled algorithms into the mac80211
module.The user interface for the rate control algorithms changes as follows:
- first the user can choose which algorithms to enable (currently only
MAC80211_RC_PID is available)
- if more than one algorithm is enabled (currently not possible since
only one algorithm is present) the user then chooses the default oneNote:
- MAC80211_RC_PID is always enables for CONFIG_EMBEDDED=nTechnical changes:
- all selected algorithms get into the mac80211 module
- net/mac80211/Makefile can now become much less complicated
- support for rc80211_pid_algo.c being modular is no longer required
- this includes unexporting mesh_plink_brokenSigned-off-by: Adrian Bunk
