fsstress - Watchdog detected hard LOCKUP on cpu 0

Bug Blocker Resolved Fixed nasf Cliff White Thu, 26 Jan 2012 20:44:10 +0000 Fri, 17 Feb 2012 13:39:05 +0000 Thu, 9 Feb 2012 08:22:05 +0000 Lustre 2.2.0 Lustre 2.2.0 0 1 <p>Fanyong</p> <p>Oleg wonders whether this might be related to the multi threaded ptlrpcd changes.</p> <p>Could you please advise whether this is the case?</p> <p>Thanks</p> <p>Peter</p> <p>From the stack, it seems that when ptlrpcd_8 tried to wakeup some other thread which was waiting for ldlm callback interpret, it found the wait queue (arg-&gt;waitq) lock was recursively locked as following:</p> <p>=======================<br/> void fastcall __wake_up(wait_queue_head_t *q, unsigned int mode,<br/> int nr_exclusive, void *key)<br/> {<br/> unsigned long flags;</p> <p>====&gt; spin_lock_irqsave(&amp;q-&gt;lock, flags);<br/> __wake_up_common(q, mode, nr_exclusive, 0, key);<br/> spin_unlock_irqrestore(&amp;q-&gt;lock, flags);<br/> }<br/> ======================</p> <p>After checking Lustre code, I do not think Lustre code can trigger recursive lock on the wait queue. But if the wait queue was released or invalid before ptlrpcd_8 called "wake_up()", then it maybe misguide the system and cause unknown behavior.</p> <p>Thread1 (some lock blocking/completion callback) was in "ldlm_run_ast_work()":<br/> ========================<br/> int ldlm_run_ast_work(struct ldlm_namespace *ns, cfs_list_t *rpc_list,<br/> ldlm_desc_ast_t ast_type)<br/> {</p> <p> struct ldlm_cb_set_arg arg = </p> { 0 } <p>;<br/> ...</p> <p> arg.threshold = 1;<br/> (step2) l_wait_event(arg.waitq, cfs_atomic_read(&amp;arg.rpcs) == 0, &amp;lwi);</p> <p>(step3) RETURN(cfs_atomic_read(&amp;arg.restart) ? -ERESTART : 0);<br/> }<br/> ========================</p> <p>Thread2 (ptlrpcd_8) was in "ldlm_cb_interpret()"<br/> ========================<br/> static int ldlm_cb_interpret(const struct lu_env *env,<br/> struct ptlrpc_request *req, void *data, int rc)<br/> {<br/> struct ldlm_cb_async_args *ca = data;<br/> struct ldlm_lock *lock = ca-&gt;ca_lock;<br/> struct ldlm_cb_set_arg *arg = ca-&gt;ca_set_arg;<br/> ...<br/> (step1) if (cfs_atomic_dec_return(&amp;arg-&gt;rpcs) &lt; arg-&gt;threshold)<br/> (step4) cfs_waitq_signal(&amp;arg-&gt;waitq);<br/> RETURN(0);<br/> }<br/> ========================</p> <p>The real processing flow maybe like:<br/> 1) thread2::step1 on CPU0<br/> 2) thread1::step2 on CPUX<br/> 3) thread1::step3 on CPUX<br/> 4) thread2::step4 on CPU0</p> <p>So when thread2 tried to wake up thread1 on the wait queue by step4, thread1 already exited the function "ldlm_run_ast_work()", so the wait queue (allocated on the stack of "ldlm_run_ast_work()") "arg-&gt;waitq" was already invalid and maybe re-allocated to other functions.</p> <p>If above case occurred, then when thread2(ptlrpcd_8) tried to perform "spin_lock_irqsave(&amp;q-&gt;lock, flags);" in function of "__wake_up()", it may be misguided to think as hard LOCKUP on cpu 0.</p> <p>Currently, there are not enough logs to prove that it is just such reason caused the failure. Anyway, above race condition should be fixed.</p> <p>The patch for above race condition:</p> <p><a href="http://review.whamcloud.com/#change,2065" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,2065</a></p> <p>FanYong</p> <p>Could you please rebase your patch on the tip of master to pickup the fix for LU797?</p> <p>Thanks</p> <p>Peter</p> <p>The patch against latest master branch with <a href="https://jira.whamcloud.com/browse/LU-797" title="Test failure on test suite ost-pools, subtest test_14, test_18, test_23" class="issue-link" data-issue-key="LU-797"><del>LU-797</del></a> fixed.</p> <p><a href="http://review.whamcloud.com/#change,2065,set2" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,2065,set2</a></p> <p>Integrated in <span class="image-wrap" style=""><img src="http://build.whamcloud.com/images/16x16/blue.png" style="border: 0px solid black" /></span> <a href="http://build.whamcloud.com/job/lustre-master/./arch=x86_64,build_type=client,distro=el5,ib_stack=ofa/462/" class="external-link" target="_blank" rel="nofollow noopener">lustre-master » x86_64,client,el5,ofa #462</a><br/> <a href="https://jira.whamcloud.com/browse/LU-1046" title=" fsstress -
