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.
Joe Perches (2):
net: Add net_ratelimited_function and net_<level>_ratelimited macros
net: Convert net_ratelimit uses to net_<level>_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".

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 ^ permalink raw reply [flat|nested] 26+ messages in thread

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.

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. johannes ^ permalink raw reply [flat|nested] 26+ messages in thread

No, you don't want that, it's different from the networking ratelimit mechanism.

Yeah, makes sense. I wonder if it makes sense to leave these under #ifdef though?

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>. ^ permalink raw reply [flat|nested] 26+ messages in thread

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. johannes ^ permalink raw reply [flat|nested] 26+ messages in thread
