Subject: [RFC/RFT] cfg80211: reg: track crda request

Track CRDA requests and handle timeout
when no answer from CRDA.
This could happen during startup when
crda binary is not available.

Tested using:
chmod 644 /sbin/crda

Tested scenarios:

1)
chmod 644 /sbin/crda
modprobe cfg80211
wait about 20 seconds
chmod 755 /sbin/crda
-> CORE request handled correctly after crda became
available, world regd

2)
chmod 644 /sbin/crda
modprobe cfg80211
wait about 10 seconds
modprobe ath10k_pci (DRIVER hint with US)
wait about 10 seconds
chmod 755 /sbin/crda
-> CORE request handled (world)
-> next DRIVER request handled (US)

3)
chmod 644 /sbin/crda
modprobe cfg80211
wait about 10 seconds
modprobe ath10k_pci (DRIVER hint with US)
wait about 10 seconds
iw reg set PL
wait about 10 seconds
chmod 755 /sbin/crda
-> CORE request handled
-> next DRIVER request handled (US)
-> next USER request handled (PL)

4)
chmod 644 /sbin/crda
modprobe cfg80211
wait about 10 seconds
iw reg set PL
wait about 10 seconds
modprobe ath10k_pci (DRIVER hint with US)
wait about 10 seconds
chmod 755 /sbin/crda
-> CORE request handled
-> next USER request handled (PL)
-> next DRIVER request handled (intersected DRIVER and USER)
Not sure this is as should be - intersection :)

@Sander @Colleen - could you chec this one?

Thanks for test :)
Are you using CONFIG_CFG80211_INTERNAL_REGDB?
I will check this option also (could be I miss cancel timeout in case
of internal regdb or 00 wasn't set correctly in db.txt).
Could you also send db.txt from net/wireless if INTERNAL_REGDB?

In case you don't use internal regdb, are you sure you choose/install
crda from menuconfig? It looks like you don't have /(s)bin/crda? Could
you confirm you have crda command installed and could be executed (I
could reproduce exactly same messages when remove +x from crda).

In case you don't use internal_regdb + db.txt nor crda I think Luis
patch could just hide problem while remove "Pending regulatory ..."
print.

With Luis patch what you see after:
iw reg set PL
iw reg get

I applied this as a single patch onto 3.15-mergewindow and this one doesn't work
for me (Luis patchset does work for me), somehow it doesn't seem to be able to set the initial domain:

The patch is good, but what's why not also apply Luis' original
("cfg80211: fix processing world regdomain when non modular") + my
suggested fix for the issue there?

The way I see it, the sooner we retry the better. Why should I see
this print instead of trying to re-process the hint?

Heh, I guess that's only fair.

I think this looks fine. My main complaint with Luis's patches (besides
reportedly breaking some other use cases) was that he was piggy-backing
on some completely unrelated thing to try to recover something. Here we
have an explicit delayed work struct so that seems fine.

And I really like the part where Janusz moves the delayed_work setting
where it belongs - the CRDA call function :)

Is this just a replacement for the second patch of Luis his series, or
a complete replacement for that series ?

Yes, it does. I applied this to mac80211-next and tested. No crashes
or problems on our test framework. I can load mac80211_hwsim reliably
with my reg domain in /etc/default/crda (debian qemu).

So either this or Arik's patch on top of Luis' work for me.
