This commit was followed by a fix (for SLOB, since SLUB/SLAB were not affected) Check commit bc417e30f8df (net: Add back alignment for size for __alloc_skb) If current kernel still crash, I believe there is a problem elsewhere (a refcounting problem) that makes underlying page being reused : The ksize(skb->head) call in pskb_expand_head() assumes skb->head is a valid zone, not an already freed one... By the way, we probably can remove (almost dead) code from pskb_expand_head() since we now place struct skb_shared_info at the end of skb->head at skb creation. I'll send this patch later for net-next diff --git a/net/core/skbuff.c b/net/core/skbuff.c index 18a3ceb..5fd67a8 100644 --- a/net/core/skbuff.c +++ b/net/core/skbuff.c @@ -892,17 +892,6 @@ int pskb_expand_head(struct sk_buff *skb, int nhead, int ntail, fastpath = atomic_read(&skb_shinfo(skb)->dataref) == delta; } - if (fastpath && - size + sizeof(struct skb_shared_info) <= ksize(skb->head)) { - memmove(skb->head + size, skb_shinfo(skb), - offsetof(struct skb_shared_info, - frags[skb_shinfo(skb)->nr_frags])); - memmove(skb->head + nhead, skb->head, - skb_tail_pointer(skb) - skb->head); - off = nhead; - goto adjust_others; - } - data = kmalloc(size + sizeof(struct skb_shared_info), gfp_mask); if (!data) goto nodata; @@ -935,7 +924,6 @@ int pskb_expand_head(struct sk_buff *skb, int nhead, int ntail, off = (data + nhead) - skb->head; skb->head = data; -adjust_others: skb->data += off; #ifdef NET_SKBUFF_DATA_USES_OFFSET skb->end = size; -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.

Has this by any chance been resolved or stopped happening? This looks for all of the world like something is stomping your sysfs dirents. I haven't seen anyone else complaining so this seems like the problem is unique to your configuration. Which suggests that it is not sysfs itself that is wrong. I have been through the code a time or two and I haven't seen anything obviously wrong. Everything that sysfs does is protected by the sysfs_mutex so the locking is very very simple. My best guess of why now is that the rbtree code make a sysfs dirent 48 bytes larger. And so it is much more exposed to these kinds of problems.

Sorry, but your subsystem was just accidentally hit by a bug in the Radeon driver, that sometimes randomly writes 0 dwords somewhere to memory after a kexec boot (see the rest of this huge thread).

Awesome. I guess that means I am only responsible for the Radeon driver having the opportunity to take that code path. It is nice to see kexec being used and being well known enough I didn't have to get involved. Eric -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.

[ After rcu lookup, we must get a stable reference, then recheck the key , or else we can manipulate something that was queued for deletion.] An example of a correct RCU conversion was done in commit 8af088710d1 (posix-timers: RCU conversion) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.

We haven't hit the poison checks, more like bad pointer derefs, almost always in SLUB coming from skb alloc or free. In my case, it's not easy to reproduce, so a bisection would be error-prone.

(ie, keyboard is working ? If it's usb it won't but if it's adb it will). You probably landed there too late tho, after the corruption happened. What would be useful would be to see if you can reproduce with SLAB and/or after backing out the cpu partial functionality.

I'm currently running with SLUB again but with /sys/kernel/slab/*/cpu_partial all set to "0" (affecting ~250 files). The box is running for some hours now and pretty loaded with both CPU and disk i/o (load 6-7, which is pretty high for this machine) and it did not oops yet. Looks like setting cpu_partial to 0 does make a difference.

Christian and I are on ppc, which uses the generic implementation of this_cpu_cmpxchg() which is not irq safe. So the above patch is needed regardless.

Sorry, I should have been clearer in that mail: the high "load" value isn't a problem - the intermittent panics are. What I meant to say was: the panics usually occur when lots of disk & cpu IO is in progress (rsync to an external but local disk over firewire). While doing this the load is usally at 3-5, but that's "normal" and expected for a machine of that age. But then the machine crashes with recent kernels. After setting the cpu_partial files to 0 I tried to reproduce the same I/O pattern, *plus* a bit more, to really stress the machine, so load went up to 6-7 and the machine did not crash. So the load of 6-7 was expected and I'm glad that the machine did not crash with that workaround. I don't know of the implications of setting cpu_partial to 0 though. As soon as the build with Christoph's one-liner is done I'll test w/o setting cpu_partial to 0 and see what it gives.

OK, with Christoph's patch applied, 3.2.0-rc2-00274-g6fe4c6d-dirty survives on this machine, with the disk & cpu workload that caused the machine to panic w/o the patch. Load was at 4-5 this time, which is expected for this box. I'll run a few more tests later on, but it seems ok for now. I couldn't resist and ran "slabinfo" anyway (after the workload!) - the box survived, nothing was printed in syslog either. Output attached. Thanks!

Allright there is an obvious issue if debugging is off since the lockless paths do not take the page lock in that case but the validation logic does. Did you run the test with debugging on or off? Not sure what the solution is but the simplest would be to disable validation if lockless is active. ^ permalink raw reply [flat|nested] 108+ messages in thread

The Redzoning (and the general object pad initialization) is outside of the slab_lock now. So I get wrong positives on those now. That is already in 3.1 as far as I know. To solve that we would have to cover a much wider area in the alloc and free with the slab lock. But I do not get the count mismatches that you saw. Maybe related to preemption. Will try that next.

It may be easier to simply disable interrupts early in __slab_free if debugging is on. Doesnt look nice right now.

Subject: slub: Lockout validation scans during freeing of object Slab validation can run right now while the slab free paths prepare the redzone fields etc around the objects in preparation of the actual freeing of the object. This can lead to false positives. Take the node lock unconditionally during free so that the validation can examine objects without them being disturbed by freeing operations.

You're using unsigned ints in: snprintf(dist_str, 40, "%lu/%lu/%d", s->slabs - s->cpu_slabs, s->partial, s->cpu_slabs); and (s->slabs - s->cpu_slabs) can get negative.

And that calculation is broken it seems. It adds up the number of objects instead of the number of slab pages. So much for review and having that stuff in -next for a long time. Sigh. Subject: slub: Fix per cpu partial statistics Support for SO_OBJECTS was not properly added to show_slab_objects(). If SO_OBJECTS is not set then the number of slab pages needs to be returned not the number of objects in the partial slabs. We do not have that number so just return 1 until we find a better way to determine that.

Some slabs are not on the partial list and are neither on the full list since they are currently on the per cpu partial lists. Thats an accounting issue introduced in 3.2 with the per cpu pages. Need to find some way to count the per cpu partial pages correctly. Could just force the per cpu pages to be empty? Subject: Switch per cpu partial page support off for debugging Otherwise we have accounting issues.

OK "slabinfo -v" is useless then. But that doesn't invalidate the BUGs that I saw during boot.

Also the use of debugging disables the use of cmpxchg_double() but not this_cpu_cmpxchg() use. See cmpxchg_double_slab() and kmem_cache_open()s determination of the __CMPXCHG_DOUBLE flag. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.

I tried to reproduce with rc3+ & rc4+ with slub or slab, did more then 20 kexec cycle with same kernel parameter and no issue. To confirm that radeon or drm is not to blame can you trigger the issue by using nomodeset kernel option (your fb rotate option is then useless). If with nomodeset you can trigger the issue can you then try to trigger it with KMS enabled and with attached patch (real ugly printk debuging) Note that i walked over the drm mode init code and i believe the root issue is that some code in the kernel do a double idr_remove/destroy which trigger the idr slub/slab error. It just happen that radeon/drm is call after the idr double free but is not the one guilty. Note that i don't understand the idr code much, so my theory can be completely wrong but attached patch might help to shed some light.

Thanks for the debugging patch Jerome. I couldn't trigger the issue with the »nomodeset« kernel option yet. But I've triggered it with KMS enabled and your patch applied: Linux version 3.2.0-rc4-00089-g621fc1e-dirty (markus@x4.trippels.de) (gcc version 4.7.0 20111201 (experimental) (GCC) ) #137 SMP PREEMPT Sat Dec 3 06:43:05 CET 2011 Command line: root=PARTUUID=6d6a4009-3a90-40df-806a-e63f48189719 init=/sbin/minit rootflags=logbsize=262144 fbcon=rotate:3 drm_kms_helper.poll=0 quiet KERNEL supported cpus: AMD AuthenticAMD BIOS-provided physical RAM map: BIOS-e820: 0000000000000100 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000e6000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 00000000dfe90000 (usable) BIOS-e820: 00000000dfe90000 - 00000000dfea8000 (ACPI data) BIOS-e820: 00000000dfea8000 - 00000000dfed0000 (ACPI NVS) BIOS-e820: 00000000dfed0000 - 00000000dff00000 (reserved) BIOS-e820: 00000000fff00000 - 0000000100000000 (reserved) BIOS-e820: 0000000100000000 - 0000000220000000 (usable) NX (Execute Disable) protection: active DMI present.

(CCing the drm list) If I had to guess it looks like 0 is getting written back to some random page by the GPU maybe, it could be that the GPU is in some half setup state at boot or on a reboot does it happen from a cold boot or just warm boot or kexec? Jerome, might be worth checking the ordering for when bus master gets enabled or if we turn off the writeback producers before writeback is enabled.

This patch is done to fix the issue described in the lkml thread : WARNING: at mm/slub.c:3357, kernel BUG at mm/slub.c:3413 https://lkml.org/lkml/2011/12/5/466 Thanks to Markus Trippelsdorf for testing this. v2 follow previous sanity work done on earlier radeon, also write reg uncondionaly and disable irq too. v3 update change log Signed-off-by: Jerome Glisse <jglisse@redhat.com> Tested-by: Markus Trippelsdorf <markus@trippelsdorf.de> --- drivers/gpu/drm/radeon/evergreen.c | 2 ++ drivers/gpu/drm/radeon/ni.c | 18 ++++++++++++++++++ drivers/gpu/drm/radeon/nid.h | 19 +++++++++++++++++++ drivers/gpu/drm/radeon/r100.c | 20 ++++++-------------- drivers/gpu/drm/radeon/r520.c | 2 +- drivers/gpu/drm/radeon/r600.c | 16 ++++++++++++++++ drivers/gpu/drm/radeon/radeon_asic.h | 2 ++ drivers/gpu/drm/radeon/rs600.c | 20 +++++++++++++++++++- drivers/gpu/drm/radeon/rs600d.h | 21 +++++++++++++++++++++ drivers/gpu/drm/radeon/rs690.c | 2 +- drivers/gpu/drm/radeon/rv515.c | 2 +- drivers/gpu/drm/radeon/rv770.c | 16 ++++++++++++++++ drivers/gpu/drm/radeon/rv770d.h | 20 ++++++++++++++++++++ 13 files changed, 142 insertions(+), 18 deletions(-) diff --git a/drivers/gpu/drm/radeon/evergreen.c b/drivers/gpu/drm/radeon/evergreen.c index 1934728..6109579 100644 --- a/drivers/gpu/drm/radeon/evergreen.c +++ b/drivers/gpu/drm/radeon/evergreen.c @@ -3249,6 +3249,8 @@ int evergreen_init(struct radeon_device *rdev) { int r; + /* restore some register to sane defaults */ + rv770_restore_sanity(rdev); /* This don't do much */ r = radeon_gem_init(rdev); if (r) diff --git a/drivers/gpu/drm/radeon/ni.c b/drivers/gpu/drm/radeon/ni.c index c15fc8b..f5d7054 100644 --- a/drivers/gpu/drm/radeon/ni.c +++ b/drivers/gpu/drm/radeon/ni.c @@ -1566,6 +1566,22 @@ int cayman_suspend(struct radeon_device *rdev) return 0; } +/* + * Due to how kexec works, it can leave the hw fully initialised when it + * boots the new kernel. + */ +static void cayman_restore_sanity(struct radeon_device *rdev) +{ + /* stop possible GPU activities */ + WREG32(IH_RB_CNTL, 0); + WREG32(IH_CNTL, 0); + WREG32(CP_ME_CNTL, CP_ME_HALT | CP_PFP_HALT); + WREG32(SCRATCH_UMSK, 0); + WREG32(CP_RB0_CNTL, RB_NO_UPDATE); + WREG32(CP_RB1_CNTL, RB_NO_UPDATE); + WREG32(CP_RB2_CNTL, RB_NO_UPDATE); +} + /* Plan is to move initialization in that function and use * helper function so that radeon_device_init pretty much * do nothing more than calling asic specific function.

Cold boot seems to be fine. Sounds like the GPU is writing to physical memory from the old mappings. This can happen to other devices if they aren't completely disabled - which may not happen since the kexec case probably avoids some of the hardware resets that occurr diring a normal reboot. I remember an ethernet chip writing into its rx ring/buffer area following a reboot (and reinstall!) when connected to a quiet lan.
