Hello,
With Linus' kernel v5.0-rc2 the blktests nvmeof-mp tests trigger the
complaint shown below. Is this a known issue?
Thanks,
Bart.

(+Paul) I'm not sure. Paul, are you perhaps aware of any open issues in the RCU infrastructure?

You may want to know that this test was run against kernel v5.0-rc5 and that that debugging option was enabled in the kernel config before I ran this test: $ grep RCU_HEAD .config CONFIG_DEBUG_OBJECTS_RCU_HEAD=y Bart. ^ permalink raw reply [flat|nested] 35+ messages in thread

I enabled CONFIG_DEBUG_OBJECTS_RCU_HEAD=y in August 2018 in the kernel config of the VM that I use to run this test. That option has been left enabled since then every time I upgraded and rebuilt the kernel. The call trace was reported while running the following shell code: git clone https://github.com/bvanassche/blktests cd blktests sudo ./check -q nvmeof-mp Gdb translates the address inside srcu_invoke_callbacks() from the call trace as follows: (gdb) list *(srcu_invoke_callbacks+0x209) 0xffffffff81181b79 is in srcu_invoke_callbacks (./include/linux/compiler.h:193). 188 }) 189 190 static __always_inline 191 void __read_once_size(const volatile void *p, void *res, int size) 192 { 193 __READ_ONCE_SIZE; 194 } 195 196 #ifdef CONFIG_KASAN 197 /* (gdb) list *(srcu_invoke_callbacks+0x1fc) 0xffffffff81181b6c is in srcu_invoke_callbacks (kernel/rcu/srcutree.c:1218). 1213 /* 1214 * Update counts, accelerate new callbacks, and if needed, 1215 * schedule another round of callback invocation. 1216 */ 1217 spin_lock_irq_rcu_node(sdp); 1218 rcu_segcblist_insert_count(&sdp->srcu_cblist, &ready_cbs); 1219 (void)rcu_segcblist_accelerate(&sdp->srcu_cblist, 1220 rcu_seq_snap(&ssp->srcu_gp_seq)); 1221 sdp->srcu_cblist_invoking = false; 1222 more = rcu_segcblist_ready_cbs(&sdp->srcu_cblist); Please let me know if you need more information.

Which explains why CONFIG_DEBUG_OBJECTS_RCU_HEAD=y wasn't helping at all, because it checks for issues in the callback lists, not in on-stack or in per-CPU structures. I believe that we can eliminate the on-stack ready_cbs variable from consideration, which leaves the per-CPU structure that is referenced by sdp. > Please let me know if you need more information. It looks to me like you need an srcu_barrier(&head->srcu) just before the call to cleanup_srcu_struct_quiesced() in nvme_free_ns_head(). Or maybe earlier in the cleanup flow, but most definitely -after- the last invocation of call_srcu(). Does that help? Or is there a call to srcu_barrier() somewhere that I am blind to?

McKenney <paulmck at linux.ibm.com> Date: Tue Feb 12 10:44:33 2019 -0800 srcu: Check for in-flight callbacks in _cleanup_srcu_struct() If someone fails to drain the corresponding SRCU callbacks (for example, by failing to invoke srcu_barrier()) before invoking either cleanup_srcu_struct() or cleanup_srcu_struct_quiesced(), the resulting diagnostic is an ambiguous use-after-free diagnostic, and even then only if you are running something like KASAN. This commit therefore improves SRCU diagnostics by adding checks for in-flight callbacks at _cleanup_srcu_struct() time. Note that these diagnostics can still be defeated, for example, by invoking call_srcu() concurrently with cleanup_srcu_struct(). Which is a really bad idea, but sometimes all too easy to do. But even then, these diagnostics have at least some probability of catching the problem.

Hmmm... I don't see how the KASAN warning could happen without srcu_struct_cleanup() or srcu_struct_cleanup_quiesced() being called. Perhaps a failure of imagination on my part. So does it seem plausible to you that one of those two has been called at the time the KASAN complaint is emitted? Thanx, Paul ^ permalink raw reply [flat|nested] 35+ messages in thread

You are getting the KASAN warning at the same place each time? This would force me to hypothesize that you are invoking srcu_struct_cleanup_quiesced() from a workqueue spawned from an SRCU callback.

Hi Paul, The KASAN warning indeed occurs at the same place each time. Have you noticed that there are no call_srcu() calls at all in the NVMe code? Since I'm not an RCU expert: what causes the SRCU code to invoke srcu_invoke_callbacks() if call_srcu() is not used? Thanks, Bart. ^ permalink raw reply [flat|nested] 35+ messages in thread

The trick is that synchronize_srcu() internally does a call_srcu(), or close enough, anyway. The reason you are using srcu_struct_cleanup_quiesced() is to avoid workqueue deadlocks?

Hi Paul, This patch introduced the srcu_struct_cleanup_quiesced() call: commit 4317228ad9b86f094d70c951f9210a8a9b2816be Author: Nitzan Carmi <nitzanc at mellanox.com> Date: Mon Apr 9 17:50:26 2018 +0300 nvme: Avoid flush dependency in delete controller flow The nvme_delete_ctrl() function queues a work item on a MEM_RECLAIM queue (nvme_delete_wq), which eventually calls cleanup_srcu_struct(), which in turn flushes a delayed work from an !MEM_RECLAIM queue. This is unsafe as we might trigger deadlocks under severe memory pressure. Since we don't ever invoke call_srcu(), it is safe to use the shiny new _quiesced() version of srcu cleanup, thus avoiding that flush dependency. This commit makes that change.

Thanx, Paul ------------------------------------------------------------------------ commit 65f1b53aeb25a9bddabd08e37bb4c7246320f993 Author: Paul E. McKenney <paulmck at linux.ibm.com> Date: Wed Feb 13 13:54:37 2019 -0800 srcu: Remove cleanup_srcu_struct_quiesced() The cleanup_srcu_struct_quiesced() function was added because NVME used WQ_MEM_RECLAIM workqueues and SRCU did not, which meant that NVME workqueues waiting on SRCU workqueues could result in deadlocks during low-memory conditions. However, SRCU now also has WQ_MEM_RECLAIM workqueues, so there is no longer a potential for deadlock. Furthermore, it turns out to be extremely hard to use cleanup_srcu_struct_quiesced() correctly due to the fact that SRCU callback invocation accesses the srcu_struct structure's per-CPU data area just after callbacks are invoked. Therefore, the usual practice of using srcu_barrier() to wait for callbacks to be invoked before invoking cleanup_srcu_struct_quiesced() fails because SRCU's callback-invocation workqueue handler might be delayed, which can result in cleanup_srcu_struct_quiesced() being invoked (and thus freeing the per-CPU data) before the SRCU's callback-invocation workqueue handler is finished using that per-CPU data. Nor is this a theoretical problem: KASAN emitted use-after-free warnings because of this problem on actual runs. In short, NVME can now safely invoke cleanup_srcu_struct(), which avoids the use-after-free scenario. And cleanup_srcu_struct_quiesced() is quite difficult to use safely. This commit therefore removes cleanup_srcu_struct_quiesced(), switching its sole user back to cleanup_srcu_struct().

But if you want me to try to push this into v5.1, I need you to very explicitly tell me that you want me to do this. Sorry to be picky, but my normal process cut off contributions to v5.0 more than a month ago, and my usual position is that a backport to -stable covers almost all use cases and reduces risk to those using mainline. Yes, RCU patches do start off under a considerable cloud of suspicion. Which is one of the reasons that RCU works at all. ;-) So again, if you need me to try to push this into v5.1, I do need an explicit request from you.

Hi Paul, If this patch will only be sent to Linus during the v5.2 merge window, will a "Cc: stable # v..." tag be added to this patch that causes this patch to be applied to kernel versions before v5.2 on which it is safe to apply this patch?

Which is what appears to be happening, again assuming that KASAN is emitting its complaint at the same place each time. Here is the sequence of events that could explain the failure, albeit with an unusual compilation and a surprisingly exact point of preemption: o nvme_ns_remove() invokes synchronize_srcu(). This causes the current context to sleep, and to be awakened from within an SRCU callback, which runs in a workqueue handler. When this callback returns, srcu_invoke_callbacks() will update callback-remaining counts in the per-CPU data associated with the srcu_struct. Let's assume that SRCU's workqueue handler is delayed just as the callback returns. o nvme_ns_remove() invokes nvme_mpath_check_last_path() and then nvme_put_ns(). o nvme_put_ns() does a kref_put(), and if the count is zero, kref_put() invokes nvme_free_ns(). o nvme_free_ns() invokes nvme_put_ns_head(), which also does a kref_put(), and if the count is zero, kref_put() invokes nvme_free_ns_head(). o nvme_free_ns_head() invokes cleanup_srcu_struct_quiesced(), which frees the per-CPU data associated with the srcu_struct. And somehow avoids the WARN_ON(rcu_segcblist_n_cbs(&sdp->srcu_cblist)). o SRCU's workqueue handler resumes, and executes this code, which references the just-freed per-CPU data: spin_lock_irq_rcu_node(sdp); rcu_segcblist_insert_count(&sdp->srcu_cblist, &ready_cbs); (void)rcu_segcblist_accelerate(&sdp->srcu_cblist, rcu_seq_snap(&ssp->srcu_gp_seq)); sdp->srcu_cblist_invoking = false; more = rcu_segcblist_ready_cbs(&sdp->srcu_cblist); spin_unlock_irq_rcu_node(sdp); But this is surprising, as it requires rcu_segcblist_insert_count() to be compiled just so: void rcu_segcblist_insert_count(struct rcu_segcblist *rsclp, struct rcu_cblist *rclp) { rsclp->len_lazy += rclp->len_lazy; /* ->len sampled locklessly. */ WRITE_ONCE(rsclp->len, rsclp->len + rclp->len); rclp->len_lazy = 0; rclp->len = 0; } To avoid the warning patch I gave you yesterday, the compiler would need to reverse the first two statements, like this: void rcu_segcblist_insert_count(struct rcu_segcblist *rsclp, struct rcu_cblist *rclp) { /* ->len sampled locklessly. */ WRITE_ONCE(rsclp->len, rsclp->len + rclp->len); rsclp->len_lazy += rclp->len_lazy; rclp->len_lazy = 0; rclp->len = 0; } Is that happening in your build? Regardless, this can happen. My usual advice would be for you to invoke cleanup_srcu_struct() instead of cleanup_srcu_struct_quiesced(), which will wait for ongoing work associated with this srcu_struct to complete. Is it possible to make this change? Thanx, Paul ^ permalink raw reply [flat|nested] 35+ messages in thread

Hi Paul, Even with this patch applied I still see the KASAN use-after-free warning: diff --git a/drivers/nvme/host/core.c b/drivers/nvme/host/core.c index 6a9dd68c0f4f..f2e47af6f8ee 100644 --- a/drivers/nvme/host/core.c +++ b/drivers/nvme/host/core.c @@ -391,6 +391,7 @@ static void nvme_free_ns_head(struct kref *ref) nvme_mpath_remove_disk(head); ida_simple_remove(&head->subsys->ns_ida, head->instance); list_del_init(&head->entry); + srcu_barrier(&head->srcu); cleanup_srcu_struct_quiesced(&head->srcu); nvme_put_subsystem(head->subsys); kfree(head); Does that mean that I misunderstood you?

That is in fact what I was asking you to do. So perhaps I misunderstood your code. Some questions: 1. Are there any other places that either cleanup_srcu_struct() or cleanup_srcu_struct_quiesced() are invoked? If so, it is possible that the others also need srcu_barrier(). 2. What prevents call_srcu() from being invoked about the time that cleanup_srcu_struct_quiesced() is called? Thanx, Paul ^ permalink raw reply [flat|nested] 35+ messages in thread
