[PATCH v2 0/3] cfg80211: respin reprocessing pending requests

[Luis R. Rodriguez]

Here's a respin. There are no code changes, I just adjusted the
commit logs as that's all the feedback I got from them, and on
the last patch I just don't think a timer is best. If a timer
is desired let me know how much time you want to set it for,
I just don't see how that's any better.

The commit log on the other ones should help let people make
decisions if the implications of not merging this, I'll let
folks make the call about whether or not some of these belong
to stable, I personally don't think so -- but some others may
disagree.

[PATCH 1/3] cfg80211: allow reprocessing of pending requests

[Luis R. Rodriguez]

In certain situations we want to trigger reprocessing
of the last regulatory hint. One situation in which
this makes sense is the case where the cfg80211 was
built-in to the kernel, CFG80211_INTERNAL_REGDB was not
enabled and the CRDA binary is on a partition not availble
during early boot. In such a case we want to be able to
re-process the same request at some other point.

When we are asked to re-process the same request we need
to be careful to not kfree it, addresses that.

This looks OK, I've applied it, but I've renamed the function since it
no longer has anything to do with the last request.

[PATCH 2/3] cfg80211: fix processing world regdomain when non modular

[Luis R. Rodriguez]

This allows processing of the last regulatory request when
we determine its still pending. Without this if a regulatory
request failed to get processed by userspace we wouldn't
be able to re-process it later. An example situation that can
lead to an unprocessed last_request is enabling cfg80211 to
be built-in to the kernel, not enabling CFG80211_INTERNAL_REGDB
and the CRDA binary not being available at the time the udev
rule that kicks of CRDA triggers.

In such a situation we want to let some cfg80211 triggers
eventually kick CRDA for us again. Without this if the first
cycle attempt to kick off CRDA failed we'd be stuck without
the ability to change process any further regulatory domains.

cfg80211 will trigger re-processing of the regulatory queue
whenever schedule_work(&reg_work) is called, currently this
happens when:

  * suspend / resume
  * disconnect
  * a beacon hint gets triggered (non DFS 5 GHz AP found)
  * a regulatory request gets added to the queue

We don't have any specific opportunistic late boot triggers
to address a late mount of where CRDA resides though, adding
that should be done separately through another patch.
Without an opportunistic fix then this fix relies at least
one of the triggeres above to happen.

Ok, applied. (with that typo there fixed)

Re: [PATCH 2/3] cfg80211: fix processing world regdomain when non modular

[Colleen T]

Hi guys,

This commit -- 5a970df8990d173e7e4092952f2e3da1de69b27d -- is causing
a regression on mac80211-next/master in our mesh test framework on
qemu.  We are using cfg80211 as a module.

In /etc/default/crda, I have:
REGDOMAIN=US

I can trigger the oops by loading mac80211_hwsim with three or more radios:

> modprobe mac80211_hwsim radios=3

It seems to be caused by updating the pending regulatory_requests
while new regulatory requests are still being added.

Here's the dmesg output which shows warnings, followed by an oops:

After that, qemu locks hard.  Seems like there might be a free on an
invalid pointer.  The crash doesn't occur with this commit reverted.

Any advice?

Thanks,
Colleen

Thanks for reporting this, I'll take a look at this right away. Are
you using wireless-testing or mac80211-next? What sha1sum are you on?

I tried to reproduce by just merging the fixes in question onto Linus'
tree and using radios=3 but no go. Can you provide the full kernel
log, I'm particularly interested in what happened before. The
COUNTRY=US on debian, which I believe you're on, should just trigger a
regulatory domain setting to US upon initialization. Depending on how
Debian does it this could either trigger as a module parameter or as a
userspace event *after* the world regdom get set.

The radios=3 alone would not do anything other than add new radios so
I see no contention on the last_request by increasing or decreasing
that. last_request is also protected by rtnl and although I was
considering a possible race against processing the same last_request
twice if you see how we call reg_process_pending_hints() on reg_todo()
its protected by rtnl_lock() so I'm a bit puzzled as to how this is
being triggered as those operations should be atomic. The other corner
case I thought of was that for userspace requests which sets a
timeout, but our when the timeout hits we also rtnl_lock() under
reg_timeout_work().

The other corner I thought of was when we reset_regdomains() but all
callers are rtnl_lock()'d. This is also the same for callers of
set_regdom().

Do you get different results if you reduce the number of radios? If so
where's the trigger point?

Just guessing, try add this one if not included in mac80211-next yet.

[PATCH 1/2] cfg80211: regulatory, reset regdomain in case of error -
this goes to 3.14 directly.

Thanks for poingint that out Janusz, that patch is not in
mac80211-next. Colleen it'd be curious if that fixes your issue but I
don't see how given that I don't see how your situation would hit the
error case. It is certainly worth trying. In any case please do
provide the full kernel log and please try the other things I
mentioned, the more detail the better.

I'm attaching a full kernel log that shows the warning being
triggered.  You are correct, I'm on debian.  In the attached case I
ran:
$ modprobe mac80211_hwsim radios=4
 I pulled the fixes onto Linus' tree and I end up with the same result.

I never see a problem for one radio or two radios.  In doing some
additional testing, I noticed I don't *always* hit this warning, but I
*usually* get it.  If I remove and load the mac80211_hwsim module
again (with three or four radios), I can quickly achieve the invalid
initiator warning.  The number of the invalid initiator is not always
the same from one run to another.

Janusz, thanks for the patch idea.  I did try it, but I'm going down a
different code path, so it didn't fix my issue.  Luis, please let me
know if there is other information that would help you.

Seems I might have found the culprit - reg_todo is called while the
request to CRDA is in flight and the patch in question causes the
already-in-process user-request to be handled again. Since it's the
same regdomain as the last request (it's the last request itself), we
get this:

treatment = __reg_process_hint_user(user_request);
if (treatment == REG_REQ_IGNORE ||
   treatment == REG_REQ_ALREADY_SET) {
kfree(user_request); <------
return treatment;
}

Can you try adding the attached patch? It just replaced relevant
kfree-s with a function that avoids freeing the last request.

Also, in the current scheme of things, CRDA might be called twice for
the same request in some corner cases, but that's not a problem, since
reg_is_valid_request() will block the second set_regdom().

Regards,
Arik

Subject: [PATCH] cfg80211: avoid freeing last_request while in flight

Avoid freeing the last request while it is being processed. This can
happen in some cases if reg_work is kicked for some reason while the
currently pending request is in flight.

+static void reg_free_last_request(struct regulatory_request *lr)

Isn't it odd to pass the last request to a function called
reg_free_last_request()?

It makes sense to me. Non-last requests are freed using kfree. The
last request needs RCU.

Yeah but there can only be one "last request", so why pass it?

oh. well that was weird before as well. :)
let's wait to see if it solves the bug? I can respin it without the arg later.

Well that's a comment for Luis I guess. Removing the print is not
really part of my patch.

[PATCH 3/3] cfg80211: processing regulatory requests on netdev notifier

[Luis R. Rodriguez]

This adds a trigger to review any pending regulatory
requests whenever an 802.11 device interface is brought
down or up. We use this as an opportunistic trigger
for checking the regulatory work queues as otherwise
they they're only checked upon an initial regulatory
request or when beacon hints are found.

This opportunistic mechanism can be used to trigger
kicking the queues regulatory queues at any time from
userspace without having to change the regulatory state.

A timer just waiting upon init is not that appropriate
as when it should be triggered will depend on systems,
a much better approach is to use and add opportunistic
triggers. The interface coming up is typically a good
indicator that filesystems have been mounted since
firmware is required for some devices.

I tested the original series and these fixed my problem and i did not
notice any regressions. Since there are no code changes:

Thanks Luis !
Hopefully it is going somewhere now after so many months.
