Well, it looks like we f*cked up something after -rc5 since I'm starting to see lockdep splats all over the place which I didn't see before. I'm running rc6 + tip/master. There was one in r8169 yesterday: https://lkml.kernel.org/r/20140722081840.GA6462@pd.tnic and now I'm seeing the following in a kvm guest. I'm adding some more lists to CC which look like might be related, judging from the stack traces. --- ...

But I'm not seeing it. The "shortest dependencies" thing seems to imply __set_task_comm(), but that only takes task_lock. Unless there is something in tip/master. Can you check that this is actually in plain -rc6? Or maybe I'm just blind. Those lockdep splats are easy to get wrong.

I don't think it's anything that's sitting in tip/master nor is it something that was introduced during this merge window. I think this has been the behavior dating back to commit 94dfd7edfd5c ("USB: HCD: support giveback of URB in tasklet context"). ^ permalink raw reply [flat|nested] 17+ messages in thread

It does not trigger everytime so you need to try a couple of iterations. I'm attaching my .config. Also, here the splats I'm seeing on my machines: https://lkml.kernel.org/r/20140722081840.GA6462@pd.tnic https://lkml.kernel.org/r/20140723095327.GA23131@pd.tnic Thanks. -- Regards/Gruss, Boris.

Well, it makes the report go away.. I'm currently leaning towards that the report is valid. We did after all change rwlock semantics, and that lockdep patch is making lockdep match those new semantics. Of course, its also possible the lockdep patch is wrong. But I'm leaning towards that the report is valid. So going by the nifty picture rostedt made: [ 61.454336] CPU0 CPU1 [ 61.454336] ---- ---- [ 61.454336] lock(&(&p->alloc_lock)->rlock); [ 61.454336] local_irq_disable(); [ 61.454336] lock(tasklist_lock); [ 61.454336] lock(&(&p->alloc_lock)->rlock); [ 61.454336] <Interrupt> [ 61.454336] lock(tasklist_lock); the fact that CPU1 holds tasklist_lock for reading, does not automagically allow CPU0 to acquire tasklist_lock for reading too, for example if CPU2 (not in the picture) is waiting to acquire tasklist_lock for writing, CPU0's read acquire is made to wait. The only kind of recursion that's safe is same CPU interrupt. Of course we should have made the lockdep change before merging qrwlock, and that's entirely my fail, but with qrwlock in these new semantics are already a reality. We could of course disable qrwlock until all such issues are cleared up (its the safe option)...

So we leave in the lockdep change and disable qrwlock ontop of tip/locking/core. Nothing's hurt yet as this whole pile is queued for 3.17 anyway. -- Regards/Gruss, Boris.

It always has been in the past, and it was certainly the *intention* that it should continue to work with qrwlock, even in the presense of pending writers on other cpu's. The qrwlock rules are that a read-lock in an interrupt is still going to be unfair and succeed if there are other readers. > the fact that CPU1 holds tasklist_lock for reading, does not > automagically allow CPU0 to acquire tasklist_lock for reading too, for > example if CPU2 (not in the picture) is waiting to acquire tasklist_lock > for writing, CPU0's read acquire is made to wait. No. That is true for qrwlock in general. But *not* in interrupt context. In interrupt context, it's unfair. At least that was the _intent_ of the code, maybe that got screwed up some way. > The only kind of recursion that's safe is same CPU interrupt. Any read-lock from an irq should still be unfair, no "same CPU" rules. See queue_read_lock_slowpath(), where it will just wait for any actual write lockers (not *waiting* writers) to go away. So by definition, of somebody else (not just the current CPU) holds the lock for reading, taking it for reading is safe on all cpu's in irq context, because we obviously won't be waiting for any actual write lock holders. So it sounds to me like the new lockdep rules in tip/master are too strict and are throwing a false positive. Linus ^ permalink raw reply [flat|nested] 17+ messages in thread

Yes, I think I may have a solution for that.

It is too late here for me to test anything but the ingridients to reproduce are nothing special. Just grab a kvm guest and pick out the locking or so options out of the .config I sent previously. Then boot it a couple of times, it triggers pretty easy after a couple of tries. -- Regards/Gruss, Boris. Sent from a fat crate under my desk.

However, I saw the following lockdep warning on a mutex when I enabled CONFIG_PROVE_LOCKING=y and CONFIG_LOCKDEP=y. My virtual machine is based on RHEL 7 beta with xfs filesystem, and the error happens for both plain 3.16-rc6 and tip/master+3.16-rc6.

The problem is you cannot use in_interrupt() in check_deadlock(). Check_deadlock() must be context invariant, it should only test the chain state and not rely on where or when its called.

Now my question is whether to do it as a new patch on top of the existing one in tip or a total replacement. I also intend to use symbolic names for the read states for better readability as suggested by John. -Longman ^ permalink raw reply [flat|nested] 17+ messages in thread

I don't care too much about the symbolic thing, partly because the actual value is not irrelevant seeing how we're peddling with bitfields. Also, its an unrelated cleanup at best. When you do re-submit extend the locking self test scenarios to cover the new semantics as well.
