Folks,
I do get errors like the following when running a new testcase in our KVM CI.
The test basically unloads kvm, reloads with with hpage=1 (enable huge page
support for guests on s390) start a guest with libvirt and hugepages, shut the
guest down and unload the kvm module.

# first bad commit: [f0a3a24b532d9a7e56a33c5112b2a212ed6ec580] mm: memcg/slab: rework non-root kmem_cache lifecycle management
unmounting /sys/fs/cgroup/memory/ before the test makes the problem go away so
it really seems to be related to the new percpu-refs from this patch.
Any ideas?

It also crashes without large pages. The trigger is really that the time between "guest is going away" and rmmod kvm is really short. i > > WARNING: CPU: 8 PID: 208 at lib/percpu-refcount.c:108 percpu_ref_exit+0x50/0x58 > Modules linked in: kvm(-) xt_CHECKSUM xt_MASQUERADE bonding xt_tcpudp ip6t_rpfilter ip6t_REJECT nf_reject_ipv6 ipt_REJECT nf_reject_ipv4 xt_conntrack ip6table_na> > CPU: 8 PID: 208 Comm: kworker/8:1 Not tainted 5.2.0+ #66 > Hardware name: IBM 2964 NC9 712 (LPAR) > Workqueue: events sysfs_slab_remove_workfn > Krnl PSW : 0704e00180000000 0000001529746850 (percpu_ref_exit+0x50/0x58) > R:0 T:1 IO:1 EX:1 Key:0 M:1 W:0 P:0 AS:3 CC:2 PM:0 RI:0 EA:3 > Krnl GPRS: 00000000ffff8808 0000001529746740 000003f4e30e8e18 0036008100000000 > 0000001f00000000 0035008100000000 0000001fb3573ab8 0000000000000000 > 0000001fbdb6de00 0000000000000000 0000001529f01328 0000001fb3573b00 > 0000001fbb27e000 0000001fbdb69300 000003e009263d00 000003e009263cd0 > Krnl Code: 0000001529746842: f0a0000407fe srp 4(11,%r0),2046,0 > 0000001529746848: 47000700 bc 0,1792 > #000000152974684c: a7f40001 brc 15,152974684e > >0000001529746850: a7f4fff2 brc 15,1529746834 > 0000001529746854: 0707 bcr 0,%r7 > 0000001529746856: 0707 bcr 0,%r7 > 0000001529746858: eb8ff0580024 stmg %r8,%r15,88(%r15) > 000000152974685e: a738ffff lhi %r3,-1 > Call Trace: > ([<000003e009263d00>] 0x3e009263d00) > [<00000015293252ea>] slab_kmem_cache_release+0x3a/0x70 > [<0000001529b04882>] kobject_put+0xaa/0xe8 > [<000000152918cf28>] process_one_work+0x1e8/0x428 > [<000000152918d1b0>] worker_thread+0x48/0x460 > [<00000015291942c6>] kthread+0x126/0x160 > [<0000001529b22344>] ret_from_fork+0x28/0x30 > [<0000001529b2234c>] kernel_thread_starter+0x0/0x10 > Last Breaking-Event-Address: > [<000000152974684c>] percpu_ref_exit+0x4c/0x58 > ---[ end trace b035e7da5788eb09 ]--- > > I have bisected this to > # first bad commit: [f0a3a24b532d9a7e56a33c5112b2a212ed6ec580] mm: memcg/slab: rework non-root kmem_cache lifecycle management > > unmounting /sys/fs/cgroup/memory/ before the test makes the problem go away so > it really seems to be related to the new percpu-refs from this patch. > > Any ideas? > > Christian >

Hello, Christian! It seems to be a race between releasing of the root kmem_cache (caused by rmmod) and a memcg kmem_cache. Does delaying rmmod for say, a minute, "resolve" the issue? I'll take a look at this code path. Thanks!

Do you know, which kmem_cache it is? If not, can you, please, figure it out? I tried to reproduce the issue, but wasn't successful so far. So I wonder what can make your case special. Thanks!

I do not know either, but have a guess. My guess would be that either the slab object or the slab page is RCU freed, and the kmem_cache destruction is called before that RCU callback has completed.

The only question is if it's the same or different issues. As soon as I'll have a fix, I'll post it here to test. Thanks!

Ah, no, the issue I've reproduced is already fixed by commit b749ecfaf6c5 ("mm: memcg/slab: fix panic in __free_slab() caused by premature memcg pointer release"). Christian, can you, please, confirm that you have this one in your tree? Also, can you, please, provide you config? And you mentioned some panics, but didn't send any dmesg messages. Can you, please, provide them? Thanks!

Those were all the WARN_ONs from percpu_ref_exit, I just had panic_on_warn enabled.

Good point! At this moment the list of children caches can't grow, only shrink.

Currently each charged slab page holds a reference to the cgroup to which it's charged. Kmem_caches are held by the memcg and are released all together with the memory cgroup. It means that none of kmem_caches are released unless at least one reference to the memcg exists, which is very far from optimal. Let's rework it in a way that allows releasing individual kmem_caches as soon as the cgroup is offline, the kmem_cache is empty and there are no pending allocations. To make it possible, let's introduce a new percpu refcounter for non-root kmem caches. The counter is initialized to the percpu mode, and is switched to the atomic mode during kmem_cache deactivation. The counter is bumped for every charged page and also for every running allocation. So the kmem_cache can't be released unless all allocations complete. To shutdown non-active empty kmem_caches, let's reuse the work queue, previously used for the kmem_cache deactivation. Once the reference counter reaches 0, let's schedule an asynchronous kmem_cache release. * I used the following simple approach to test the performance (stolen from another patchset by T. Harding): time find / -name fname-no-exist echo 2 > /proc/sys/vm/drop_caches repeat 10 times Results: orig patched real 0m1.455s real 0m1.355s user 0m0.206s user 0m0.219s sys 0m0.855s sys 0m0.807s real 0m1.487s real 0m1.699s user 0m0.221s user 0m0.256s sys 0m0.806s sys 0m0.948s real 0m1.515s real 0m1.505s user 0m0.183s user 0m0.215s sys 0m0.876s sys 0m0.858s real 0m1.291s real 0m1.380s user 0m0.193s user 0m0.198s sys 0m0.843s sys 0m0.786s real 0m1.364s real 0m1.374s user 0m0.180s user 0m0.182s sys 0m0.868s sys 0m0.806s real 0m1.352s real 0m1.312s user 0m0.201s user 0m0.212s sys 0m0.820s sys 0m0.761s real 0m1.302s real 0m1.349s user 0m0.205s user 0m0.203s sys 0m0.803s sys 0m0.792s real 0m1.334s real 0m1.301s user 0m0.194s user 0m0.201s sys 0m0.806s sys 0m0.779s real 0m1.426s real 0m1.434s user 0m0.216s user 0m0.181s sys 0m0.824s sys 0m0.864s real 0m1.350s real 0m1.295s user 0m0.200s user 0m0.190s sys 0m0.842s sys 0m0.811s So it looks like the difference is not noticeable in this test.
