net_ratelimit() like __ratelimit() is too easy to misuse.
Add simplifying macros similar to pr_<level>_ratelimited
that combines the test of net_ratelimit and logging.

__ratelimit() can be considered an inverted bool test because
it returns true when not ratelimited. Several tests in the
kernel tree use this __ratelimit() function incorrectly.
No net_ratelimit uses are incorrect currently though.
Most uses of net_ratelimit are to log something via printk or
pr_<level>.
In order to minimize the uses of net_ratelimit, and to start
standardizing the code style used for __ratelimit() and net_ratelimit(),
add a net_ratelimited_function() macro and net_<level>_ratelimited()
logging macros similar to pr_<level>_ratelimited that use the global
net_ratelimit instead of a static per call site "struct ratelimit_state".

Standardize the net core ratelimited logging functions.
Coalesce formats, align arguments.
Change a printk then vprintk sequence to use printf extension %pV.

These look fine to me so I've applied them to net-next and am
sanity checking the build right now.

OK, but fyi, there's a possible issue with !CONFIG_DEBUG
builds because these patches converted some uses of
if (net_ratelimit())
printk(KERN_DEBUG ...
to
net_dbg_ratelimited()
These messages are no longer emitted when DEBUG isn't defined
and not using dynamic_debug. I'm not sure that's a real
problem, but it's a difference.
I could produce a net_printk_ratelimited that would keep
the original behavior if necessary.
net_printk_ratelimited(KERN_DEBUG etc...)
cheers, Joe

If you want debugging messages you would turn on dynamic_debug
via sysctl or whatever, not define DEBUG in your sources.
I don't think we should add yet another interface just to get
KERN_DEBUG in there.

I don't think it's worth the hassle, we'd rather get people
into the habit of using dynamic_debug.

But don't you have to do something in the sources to actually get
dynamic_debug enabled? I'm concerned this will make mac80211 debugging
inconsistent - the normal bits are just printk() still, and the
rate-limited bits need some special enabling? That seems odd.

You can turn them all off or on with a simple flip of a boolean switch
at run-time. Or, alternatively, you can turn them on or off in a
finer grained manner with other run-time facilities.
There should be a transition away from explicit KERN_DEBUG.

Btw, what would the difference be to just plain printk_ratelimited()?

I support that, but I think it's confusing to have things mixed. Also,
we seem to have printk_ratelimit(), so I'd prefer to have that used in
mac80211 instead until everything there moves over to newer facilities.

printk_ratelimited() drops a local ratelimit cookie into each call-site,
whereas we have a global one for the networking which these new interfaces
use.
Joe explained this completely in his 0/2 patch posting.

No, you don't want that, it's different from the networking ratelimit
mechanism. Joe explained this, and I just explaing it to you once
again in another reply.

I don't see that explicitly mentioned, but it doesn't matter much
anyway.
In the mac80211 case, messages are warnings/hints to the user, we just
don't want them to flood the logs too much. I'd rather have that kind of
change (limit cookie per callsite) in the rate limiting semantics than
the change in the when it gets printed at all.
I simply feel that obscuring the debugging even further wouldn't be a
good thing to do right now. I'd rather have somebody convert all of it
to the new debugging infrastructure but that seems a lot more effort
than changing these back to something that isn't impacted by dynamic
printk.

Then they aren't KERN_DEBUG, they are KERN_INFO or KERN_WARN.

Standardize the debugging to be able to use dynamic_debug.
Coalesce formats, align arguments.

Simplify the use of #ifdef CONFIG_MAC80211_HT_DEBUG/#endif
by adding a logging macro to encapsulate the test.
Convert the appropriate uses too.

Cc: linux-wireless, netdev, linux-kernel
Simplify the use of #ifdef CONFIG_MAC80211_IBSS_DEBUG/#endif
by adding a logging macro to encapsulate the test.
Convert the appropriate uses too.

I really think this is the right thing to do and I hope the wireless
folks integrate this.
I am well aware that you guys intend for some of these messages to be
indications and notifications the user is intended to SEE, but in the
cases where that is true KERN_DEBUG is absolutely not appropriate.
You should be using KERN_INFO or KERN_WARN in those situations
instead.
Thanks.

Yeah, makes sense. I wonder if it makes sense to leave these under
#ifdef though? Why #ifdef something if it's going to be invisible most
of the time anyway?

I don't understand your point.
#ifdef removal is a good thing.

Yeah, but you left a lot of them under ifdef, and I'm wondering why you
didn't remove them, or if you should, or ...

Those mostly use other different
#ifdef CONFIG_SOME_OTHER_CONTROL elements.
There are I think 3 that I left because they do
not use printk/pr_level but use wiphy_<level> or
netdev_<level>.

Hmm, ok. I guess I need to just look at them and decide what should be
what. Thanks for the preparation work though :)
