The comment is interesting. /* * page_zone is not safe to call in this context when * CONFIG_HOLES_IN_ZONE is set. This bug check is probably redundant * anyway as we check zone boundaries in move_freepages_block(). * Remove at a later date when no bug reports exist related to * grouping pages by mobility */ but we should work out why we're suddenly getting a range which crosses zones before we just zap it.

Honestly, I think VM_BUG_ON() is complete garbage to begin with. We know the code can't depend on it, since it's only enabled for VM developers. And if it ever triggers, it doesn't get logged because the machine is dead (since the VM code almost always holds critical locks). So it's exactly the worst kind of BUG_ON. Can we turn VM_BUG_ON() into "WARN_ON_ONCE()" and be done with it? The VM developers will actually get better reports, and non-vm-developers don't have dead machines.

Sometimes, however, it is better to crash. Examples include the possibility of user data getting corrupted, and security vulnerabilities. Once, kernel gets into a broken state, such as invalid pagetable entries, but continues executing data written to disk, nvram, or sent over network is unreliable. Another example include crash dumps that are hard to analyze as the corruption is long passed. Pavel ^ permalink raw reply [flat|nested] 24+ messages in thread

What were the qemu arguments if so? No, this is actually on raw hardware. I've had a unstable machine for the last couple of weeks, and it just hung with no sign of where. I finally reproduced it reliably by booting with less memory ("mem=6G") and then putting the machine under memory pressure and then I could get it on the console when the machine died. Before that it was just an occasional hung machine randomly every other day or whatever. If it reproduces in emulation, that will certainly make it easier to see the messages. But since I suspect it might be related to having that odd (read: real life) e820 table setup, it might not reproduce in emulation. At least when I boot up in lkvm-run, I don't see those ACPI tables and ACPI NVS sections, which seems to be related to this. I'm attaching my kernel-config (this is the non-debug one - it does have CONFIG_DEBUG_VM, but none of the other debug options I ran with for the last few days in the hope of catching it earlier).

I believe, the problem was narrowed down to this commit: 124049decbb1 x86/e820: put !E820_TYPE_RAM regions into memblock.reserved The commit intends to zero memmap (struct pages) for every hole in e820 ranges by marking them reserved in memblock. Later zero_resv_unavail() walks through memmap ranges and zeroes struct pages for every page that is reserved, but does not have a physical backing known by kernel.

That just looks incoredibly buggy. You can't just memset() the 'struct page' to zero after it's been set up. That also zeroes page->flags, but page->flags contains things like the zone and node ID. That would explain the completely bogus "DMA" zone. That's not the real zone, it's just that page_zonenr() returns 0 because of an incorrect clearing of page->flags. And it would also completely bugger pfn_to_page() for CONFIG_DISCONTIGMEM, because the way that works is that it looks up the node using page_to_nid(), and then looks up the pfn by using the per-node pglist_data ->node_mem_map (that the 'struct page' is supposed to be a pointer into). So zerong the page->flags after it has been set up is completely wrong as far as I can see. It literally invalidates 'struct page' and makes various core VM function assumptions stop working. As an example, it makes "page_to_pfn -> pfn_to_page" not be the identity transformation, which could result in totally random behavior. And it definitely explains the whole "oh, now the zone ID doesn't match" issue. It &*should* have been zone #1 ("DMA32"), but it got cleared and that made it zone #0 ("DMA"). So yeah, this looks like the cause of it. And it could result in any number of really odd problems, so this could easily explain the syzbot failures and reboots at bootup too. Who knows what happens when pfn_to_page() doesn't work any more. Should we perhaps just revert 124049decbb1 x86/e820: put !E820_TYPE_RAM regions into memblock.reserved f7f99100d8d9 mm: stop zeroing memory during allocation in vmemmap it still reverts fairly cleanly (there's a trivial conflict with the older commit).

That should not be happening, unless there is a bug. zero_resv_unavail() is supposed be zeroing struct pages that were not setup. Struct pages are configured here: free_area_init_nodes() free_area_init_node() free_area_init_core() memmap_init() memmap_init_zone() if (pfn_valid(pfn)) <--- Actually few more checks: early_pfn_valid(pfn), early_pfn_in_nid(pfn, nid) __init_single_page(pfn_to_page(pfn)) mm_zero_struct_page(page); set the other fields in struct page zero_resv_unavail(); <-- is called at the end of free_area_init_nodes() if (!pfn_valid(pfn)) mm_zero_struct_page(pfn_to_page(pfn)); <- So the idea that we zero only the part of memmap that was not initialized in __init_single_page(). We want to zero those struct pages so we do not have uninitialized data accessed by various parts of the code that rounds down large pages and access the first page in section without verifying that the page is valid.

Well, it does seem to happen. My memory stress-tester has been running for about half an hour now with the revert I posted - it used to trigger the problem in maybe ~5 minutes before. So I do think that revert fixes it for me. No guarantees, but since I figured out how to trigger it, it's been fairly reliable. > We want to zero those struct pages so we do not have uninitialized > data accessed by various parts of the code that rounds down large > pages and access the first page in section without verifying that the > page is valid. The example of this is described in commit that > introduced zero_resv_unavail() I'm attaching the relevant (?) parts of dmesg, which has the node ranges, maybe you can see what the problem with the code is. (NOTE! This dmesg is with that "mem=6G" command line option, which causes that e820: remove [mem 0x180000000-0xfffffffffffffffe] usable line - that's just because it's my stress-test boot. It happens with or without it, but without the "mem=6G" it took days to trigger). I'm more than willing to test patches (either for added information or for testing fixes), although I think I'm getting off the computer for today.

Reverting "f7f99100d8d9 mm: stop zeroing memory during allocation in vmemmap" would introduce a significant boot performance regression, as we would zero the whole memmap twice during boot. Later, I will introduce a more detailed fix that will get rid of zero_resv_unavail() entirely, and instead will zero skipped struct pages in memmap_init_zone(), where it should be done.

Recently, there was a change which zeroed all memmap for all holes in e820. Unfortunately, it introduced a bug that is discussed here: https://www.spinics.net/lists/linux-mm/msg156764.html Linus, also saw this bug on his machine, and confirmed that pulling commit 124049decbb1 ("x86/e820: put !E820_TYPE_RAM regions into memblock.reserved") fixes the issue. The problem is that we incorrectly zero some struct pages after they were setup. The fix is to zero unavailable struct pages prior to initializing of struct pages. A more detailed fix should come later that would avoid double zeroing cases: one in __init_single_page(), the other one in zero_resv_unavail().

I guess it should be marked for stable, because it appears that this problem got back-ported to stable (I find that Laura reports it for 4.17.4, but not 4.17.3).

I am sorry but I simply do not see it. zero_resv_unavail should be touching only reserved memory ranges and those are not initialized anywhere. So who has reused them and put them to normal available memory to be initialized by free_area_init_node[s]? The patch itself should be safe because reserved and available memory ranges should be disjoint so the ordering shouldn't matter.

Thats exactly right, and I am also not sure why this is happening, there must be some overlapping happening that just should not. I will study it later.

Maybe a stupid question, but I do not see it from the code (this init code is just to complex to keep it cached in head so I always have to study the code again and again, sigh). So what exactly prevents memmap_init_zone to stumble over reserved regions?

Hi Michal, This is not a stupid question. I figured out how this whole thing became broken: Revert "mm: page_alloc: skip over regions of invalid pfns where possible" caused that. Because, before that was reverted, memmap_init_zone() would use memblock.memory to check that only pages that have physical backing are initialized. But, now after that was reverted zer_resv_unavail() scheme became totally broken. The concept is quite easy: zero all the allocated memmap memory that has not been initialized by memmap_init_zone(). So, I think I will modify memmap_init_zone() to zero the skipped pfns that have memmap backing. But, that requires more thinking.

I think we are not really skiping reserved regions in memmap_init_zone(). memmap_init_zone() gets just called being size the subtract of zone_end_pfn - zone_start_pfn, and I don't see that we're checking if those pfn's fall in reserved regions. To get a better insight, I just put a couple of printk's: kernel: zero_resv_unavail: start-end: 0x9f000-0x100000 kernel: zero_resv_unavail: pfn: 0x9f kernel: zero_resv_unavail: pfn: 0xa0 kernel: zero_resv_unavail: pfn: 0xa1 kernel: zero_resv_unavail: pfn: 0xa2 kernel: zero_resv_unavail: pfn: 0xa3 kernel: zero_resv_unavail: pfn: 0xa4 kernel: zero_resv_unavail: pfn: 0xa5 kernel: zero_resv_unavail: pfn: 0xa6 kernel: zero_resv_unavail: pfn: 0xa7 kernel: zero_resv_unavail: pfn: 0xa8 kernel: zero_resv_unavail: pfn: 0xa9 ... ... kernel: memmap_init_zone: pfn: 9f kernel: memmap_init_zone: pfn: a0 kernel: memmap_init_zone: pfn: a1 kernel: memmap_init_zone: pfn: a2 kernel: memmap_init_zone: pfn: a3 kernel: memmap_init_zone: pfn: a4 kernel: memmap_init_zone: pfn: a5 kernel: memmap_init_zone: pfn: a6 kernel: memmap_init_zone: pfn: a7 kernel: memmap_init_zone: pfn: a8 kernel: memmap_init_zone: pfn: a9 kernel: memmap_init_zone: pfn: aa kernel: memmap_init_zone: pfn: ab kernel: memmap_init_zone: pfn: ac kernel: memmap_init_zone: pfn: ad kernel: memmap_init_zone: pfn: ae kernel: memmap_init_zone: pfn: af kernel: memmap_init_zone: pfn: b0 kernel: memmap_init_zone: pfn: b1 kernel: memmap_init_zone: pfn: b2 The printk from memmap_init_zone has already passed the checks about early_pfn_ etc. So, reverting Pavel's fix would twist this, and we'd end up zeroing pages that are already set up in memmap_init_zone() (as we already had). -- Oscar Salvador SUSE L3 ^ permalink raw reply [flat|nested] 24+ messages in thread

WTF? That's just odd. But everything seems to work fine, and now it doesn't crash. But there's something really odd going on wrt page_zone() and/or page_to_pfn(). page_to_pfn() implies this is just regular memory in the 3GB area. It is likely related to this: BIOS-e820: [mem 0x00000000c0b33000-0x00000000c226cfff] reserved BIOS-e820: [mem 0x00000000c226d000-0x00000000c227efff] ACPI data BIOS-e820: [mem 0x00000000c227f000-0x00000000c2439fff] usable BIOS-e820: [mem 0x00000000c243a000-0x00000000c2a61fff] ACPI NVS BIOS-e820: [mem 0x00000000c2a62000-0x00000000c32fefff] reserved BIOS-e820: [mem 0x00000000c32ff000-0x00000000c32fffff] usable BIOS-e820: [mem 0x00000000c3300000-0x00000000c7ffffff] reserved I dunno.

Given that they are reserved, that by itself probably does not matter in the first place, and I'd be more interested in understanding where those intervals are coming from that start or end right in the middle of a reserved region. ^ permalink raw reply [flat|nested] 24+ messages in thread
