[patch 02/19] mm: fix initialization of struct page for holes in memory layout

by Andrew Morton

From: Mike Rapoport <rppt(a)linux.ibm.com> Subject: mm: fix initialization of struct page for holes in memory layout There could be struct pages that are not backed by actual physical memory. This can happen when the actual memory bank is not a multiple of SECTION_SIZE or when an architecture does not register memory holes reserved by the firmware as memblock.memory. Such pages are currently initialized using init_unavailable_mem() function that iterates through PFNs in holes in memblock.memory and if there is a struct page corresponding to a PFN, the fields if this page are set to default values and the page is marked as Reserved. init_unavailable_mem() does not take into account zone and node the page belongs to and sets both zone and node links in struct page to zero. On a system that has firmware reserved holes in a zone above ZONE_DMA, for instance in a configuration below: # grep -A1 E820 /proc/iomem 7a17b000-7a216fff : Unknown E820 type 7a217000-7bffffff : System RAM unset zone link in struct page will trigger VM_BUG_ON_PAGE(!zone_spans_pfn(page_zone(page), pfn), page); because there are pages in both ZONE_DMA32 and ZONE_DMA (unset zone link in struct page) in the same pageblock. Update init_unavailable_mem() to use zone constraints defined by an architecture to properly setup the zone link and use node ID of the adjacent range in memblock.memory to set the node link.

[patch 01/19] x86/setup: don't remove E820_TYPE_RAM for pfn 0

by Andrew Morton

From: Mike Rapoport <rppt(a)linux.ibm.com> Subject: x86/setup: don't remove E820_TYPE_RAM for pfn 0 Patch series "mm: fix initialization of struct page for holes in memory layout", v3. Commit 73a6e474cb37 ("mm: memmap_init: iterate over memblock regions rather that check each PFN") exposed several issues with the memory map initialization and these patches fix those issues. Initially there were crashes during compaction that Qian Cai reported back in April [1]. It seemed back then that the problem was fixed, but a few weeks ago Andrea Arcangeli hit the same bug [2] and there was an additional discussion at [3]. [1] https://lore.kernel.org/lkml/8C537EB7-85EE-4DCF-943E-3CC0ED0DF56D@lca.pw [2] https://lore.kernel.org/lkml/20201121194506.13464-1-aarcange@redhat.com [3] https://lore.kernel.org/mm-commits/20201206005401.qKuAVgOXr%akpm@linux-foun… This patch (of 2): The first 4Kb of memory is a BIOS owned area and to avoid its allocation for the kernel it was not listed in e820 tables as memory. As the result, pfn 0 was never recognised by the generic memory management and it is not a part of neither node 0 nor ZONE_DMA. If set_pfnblock_flags_mask() would be ever called for the pageblock corresponding to the first 2Mbytes of memory, having pfn 0 outside of ZONE_DMA would trigger VM_BUG_ON_PAGE(!zone_spans_pfn(page_zone(page), pfn), page); Along with reserving the first 4Kb in e820 tables, several first pages are reserved with memblock in several places during setup_arch(). These reservations are enough to ensure the kernel does not touch the BIOS area and it is not necessary to remove E820_TYPE_RAM for pfn 0. Remove the update of e820 table that changes the type of pfn 0 and move the comment describing why it was done to trim_low_memory_range() that reserves the beginning of the memory.

This happened when shmem_fallocate(punch hole)'s unmap_mapping_range() reaches zap_pmd_range()'s call to __split_huge_pmd(). The same deadlock could occur when partially truncating a mapped huge tmpfs file, or using fallocate(FALLOC_FL_PUNCH_HOLE) on it. __split_huge_pmd()'s page lock was added in 5.8, to make sure that any concurrent use of reuse_swap_page() (holding page lock) could not catch the anon THP's mapcounts and swapcounts while they were being split. Fortunately, reuse_swap_page() is never applied to a shmem or file THP (not even by khugepaged, which checks PageSwapCache before calling), and anonymous THPs are never created in shmem or file areas: so that __split_huge_pmd()'s page lock can only be necessary for anonymous THPs, on which there is no risk of deadlock with i_mmap_rwsem.

Before the patch, a write to memory.high would first put the new limit in place for the workload, and then reclaim the requested delta. After the patch, the kernel tries to reclaim the delta before putting the new limit into place, in order to not overwhelm the workload with a sudden, large excess over the limit. However, if reclaim is actively racing with new allocations from the uncurbed workload, it can keep the write() working inside the kernel indefinitely. This is causing problems in Facebook production. A privileged system-level daemon that adjusts memory.high for various workloads running on a host can get unexpectedly stuck in the kernel and essentially turn into a sort of involuntary kswapd for one of the workloads. We've observed that daemon busy-spin in a write() for minutes at a time, neglecting its other duties on the system, and expending privileged system resources on behalf of a workload. To remedy this, we have first considered changing the reclaim logic to break out after a couple of loops - whether the workload has converged to the new limit or not - and bound the write() call this way. However, the root cause that inspired the sequence change in the first place has been fixed through other means, and so a revert back to the proven limit-setting sequence, also used by memory.max, is preferable. The sequence was changed to avoid extreme latencies in the workload when the limit was lowered: the sudden, large excess created by the limit lowering would erroneously trigger the penalty sleeping code that is meant to throttle excessive growth from below. Allocating threads could end up sleeping long after the write() had already reclaimed the delta for which they were being punished. However, erroneous throttling also caused problems in other scenarios at around the same time. This resulted in commit b3ff92916af3 ("mm, memcg: reclaim more aggressively before high allocator throttling"), included in the same release as the offending commit. When allocating threads now encounter large excess caused by a racing write() to memory.high, instead of entering punitive sleeps, they will simply be tasked with helping reclaim down the excess, and will be held no longer than it takes to accomplish that. This is in line with regular limit enforcement - i.e. if the workload allocates up against or over an otherwise unchanged limit from below. With the patch breaking userspace, and the root cause addressed by other means already, revert it again.

This doesn't seem like it will cause any big functional problems other than some excess flushing for VM_MAP_PUT_PAGES allocations. Redefine VM_MAP_PUT_PAGES to have its own value. Also, move the comment and remove whitespace for VM_KASAN such that the flags lower down are less likely to be missed in the future.
