	---[ end Kernel panic - not syncing: Fatal exception in interrupt ]---

We first encountered this issue under huge network traffic (system image
download), and I was able to reproduce by simply sending a big packet
with `ping -s 65507 <ip>`, which crashes the kernel every single time.

The BUG only happens when using `slub_debug=F` on the command-line (to
enable SLAB_CONSISTENCY_CHECKS), otherwise the double free is not
reported and the system keeps running.

The code path is:
	net_rx_action
	  __kfree_skb_flush
		kmem_cache_free_bulk()  # skbuff_head_cache
		  slab_free()
			do_slab_free()
			  __slab_free()
				free_debug_processing()
				  free_consistency_check()
					object_err()    # "Object already free"
					  print_trailer()
						print_tracking()    # !(s->flags & SLAB_STORE_USER) => return;
						print_page_info()   # "INFO: Slab ..."
						pr_err("INFO: Object ...", ..., get_freepointer(s, p))
						  get_freepointer()
						    freelist_dereference() # NULL pointer dereference

Enabling KASAN shows less info because the NULL pointer dereference then
apparently happens before reaching free_debug_processing().

Bisection points to the following commit: 1b7e816fc80e ("mm: slub: Fix
slab walking for init_on_free"), and indeed the BUG is not triggered
when init_on_free is disabled.

Since you have a repro, could you start a bisection ?

Thanks !

From my previous email:

	"Bisection points to the following commit: 1b7e816fc80e ("mm: slub:
	Fix slab walking for init_on_free"), and indeed the BUG is not
	triggered when init_on_free is disabled."

Or are you meaning something else?

You could change slub_debug parameter to:
slub_debug=FU,skbuff_head_cache

That will also print out who previously allocated and freed the double
freed object. And limit all the tracking just to the affected cache.

That could be either buggy SLUB code, or the commit somehow exposed a
real bug in skbuff users.

Could you please give more specific reproduction steps?
I've checked out v5.3.8 from
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git, ran
`make defconfig` and added CONFIG_SLUB_DEBUG_ON=y.
Then I've built the kernel, ran it on QEMU with slub_debug=F and
init_on_free=1, SSHed into the machine and executed `ping -s 65507
127.0.0.1`
This however didn't trigger any crashes.
Am I missing something?

Thanks, I did not know about that.

However, as kind of expected, I get a BUG due to a NULL pointer
dereference in print_track():

I tried reverting 1b7e816fc80e ("mm: slub: Fix slab walking for
init_on_free") or disabling init_on_free, but then again I cannot
reproduce the bug and nothing is logged.

Right. At first I thought about some incompatibility between
init_on_free and SLAB_CONSISTENCY_CHECKS, but in that case why would it
only happen with skbuff_head_cache? On the other hand, if it's a bug in
skbuff users, why is the on_freelist() check in free_consistency_check()
not detecting anything when init_on_free is disabled?

Ah, I didn't read properly your initial mail, that there's a null
pointer deference during the consistency check.

That's curious, yeah.

I vaguely suspect the code in the commit 1b7e816fc80e you bisected,
where in slab_free_freelist_hook() in the first iteration, we have void
*p = NULL; and set_freepointer(s, object, p); will thus write NULL into
the freelist. Is is the NULL we are crashing on? The code seems to
assume that the freelist is rewritten later in the function, but that
part is only active with some CONFIG_ option(s), none of which might be
enabled in your case?
But I don't really understand what exactly this function is supposed to
do. Laura, does my theory make sense?

Thanks,
Vlastimil

I cannot reproduce either when pinging the loopback interface. Please
try pinging another machine.

I also attached the kernel configuration I use in a QEMU VM to reproduce
the bug, as well as the VM's settings.

Loaded modules listed in the kernel panic trace are:
	virtio_scsi virtio_net net_failover failover virtio_mmio
	virtio_input virtio_gpu virtio_crypto crypto_engine virtio_console
	virtio_balloon uhci_hcd uas usb_storage rtc_cmos qxl qemu_fw_cfg
	psmouse mousedev ehci_pci ehci_hcd button bochs_drm drm_vram_helper
	ttm virtio_rng

Hope this helps,

The note about getting re-written is referring to the fact that the trick
with the bulk free is that we build the detached freelist and then when
we do the cmpxchg it's getting (correctly) updated there.

But looking at this again, I realize this function still has a more
fundamental problem: walking the freelist like this means we actually
end up reversing the list so head and tail are no longer pointing
to the correct blocks. I was able to reproduce the issue by writing a
simple kmem_cache_bulk_alloc/kmem_cache_bulk_free function. I'm
guessing that the test of ping with an unusual size was enough to
regularly trigger a non-trivial bulk alloc/free.

The fix I gave before fixed part of the problem but not all of it.
At this point we're basically duplicating the work of the loop
below so I think we can just combine it. Was there a reason this
wasn't just combined in the first place?

Good catch about the freelist inversion, I was actually starting to
wonder whether it was really intended. Anyway, I tested your patch (see
one tiny inline comment below) and it seems to run fine for now, without
me being able to reproduce the bug anymore.
