2021-01-24proc_sysctl: fix oops caused by incorrect command parametersXiaoming Ni1-1/+6
The process_sysctl_arg() does not check whether val is empty before invoking strlen(val). If the command line parameter () is incorrectly configured and val is empty, oops is triggered. For example: "hung_task_panic=1" is incorrectly written as "hung_task_panic", oops is triggered. The call stack is as follows: Kernel command line: .... hung_task_panic ...... Call trace: __pi_strlen+0x10/0x98 parse_args+0x278/0x344 do_sysctl_args+0x8c/0xfc kernel_init+0x5c/0xf4 ret_from_fork+0x10/0x30 To fix it, check whether "val" is empty when "phram" is a sysctl field. Error codes are returned in the failure branch, and error logs are generated by parse_args().

2021-01-24sparc/mm/highmem: flush cache and TLBThomas Gleixner1-4/+5
Patch series "mm/highmem: Fix fallout from generic kmap_local conversions". The kmap_local conversion wreckaged sparc, mips and powerpc as it missed some of the details in the original implementation. This patch (of 4): The recent conversion to the generic kmap_local infrastructure failed to assign the proper pre/post map/unmap flush operations for sparc. Sparc requires cache flush before map/unmap and tlb flush afterwards.

2021-01-24mm: fix page reference leak in soft_offline_page()Dan Williams1-4/+16
The conversion to move pfn_to_online_page() internal to soft_offline_page() missed that the get_user_pages() reference taken by the madvise() path needs to be dropped when pfn_to_online_page() fails. Note the direct sysfs-path to soft_offline_page() does not perform a get_user_pages() lookup. When soft_offline_page() is handed a pfn_valid() && !pfn_to_online_page() pfn the kernel hangs at dax-device shutdown due to a leaked reference.

2021-01-24kasan, mm: fix resetting page_alloc tags for HW_TAGSAndrey Konovalov1-0/+2
A previous commit added resetting KASAN page tags to kernel_init_free_pages() to avoid false-positives due to accesses to metadata with the hardware tag-based mode. That commit did reset page tags before the metadata access, but didn't restore them after. As the result, KASAN fails to detect bad accesses to page_alloc allocations on some configurations. Fix this by recovering the tag after the metadata access.

2021-01-24kasan: fix HW_TAGS boot parametersAndrey Konovalov2-66/+38
The initially proposed KASAN command line parameters are redundant. This change drops the complex "kasan.mode=off/prod/full" parameter and adds a simpler kill switch "kasan=off/on" instead. The new parameter together with the already existing ones provides a cleaner way to express the same set of features. The full set of parameters with this change: kasan=off/on - whether KASAN is enabled kasan.fault=report/panic - whether to only print a report or also panic kasan.stacktrace=off/on - whether to collect alloc/free stack traces Default values: kasan=on kasan.fault=report kasan.stacktrace=on (if CONFIG_DEBUG_KERNEL=y) kasan.stacktrace=off (otherwise) Link: https://linux-review.googlesource.com/id/Ib3694ed90b1e8ccac6cf77dfd301847af4aba7b8 Link: https://lkml.kernel.org/r/4e9c4a4bdcadc168317deb2419144582a9be6e61.1610736745.git.andreyknvl@google.com Signed-off-by: Andrey Konovalov <andreyknvl@google.com> Reviewed-by: Vincenzo Frascino <vincenzo.frascino@arm.com> Reviewed-by: Marco Elver <elver@google.com> Cc: Dmitry Vyukov <dvyukov@google.com> Cc: Alexander Potapenko <glider@google.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Will Deacon <will.deacon@arm.com> Cc: Andrey Ryabinin <aryabinin@virtuozzo.com> Cc: Peter Collingbourne <pcc@google.com> Cc: Evgenii Stepanov <eugenis@google.com> Cc: Branislav Rankov <Branislav.Rankov@arm.com> Cc: Kevin Brodsky <kevin.brodsky@arm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

In the test case for kasan_remove_zero_shadow(): shadow_start: 0xffffffb802000000, shadow end: 0xffffffbfbe000000 3-level page table: PUD_SIZE: 0x40000000 PMD_SIZE: 0x200000 PAGE_SIZE: 4K 0xffffffbf80000000 ~ 0xffffffbfbdf80000 will not be removed because in kasan_remove_pud_table(), kasan_pmd_table(*pud) is true but the next address is 0xffffffbfbdf80000 which is not aligned to PUD_SIZE. In the correct condition, this should fallback to the next level kasan_remove_pmd_table() but the condition flow always continue to skip the unaligned part. Fix by correcting the condition when next and addr are neither aligned.

Currently the kernel is not correctly updating the numa stats for NR_FILE_PAGES and NR_SHMEM on THP migration. Fix that. For NR_FILE_DIRTY and NR_ZONE_WRITE_PENDING, although at the moment there is no need to handle THP migration as kernel still does not have write support for file THP but to be more future proof, this patch adds the THP support for those stats as well.

2021-01-24mm: memcg/slab: optimize objcg stock drainingRoman Gushchin1-3/+1
Imran Khan reported a 16% regression in hackbench results caused by the commit f2fe7b09a52b ("mm: memcg/slab: charge individual slab objects instead of pages"). The regression is noticeable in the case of a consequent allocation of several relatively large slab objects, e.g. skb's. As soon as the amount of stocked bytes exceeds PAGE_SIZE, drain_obj_stock() and __memcg_kmem_uncharge() are called, and it leads to a number of atomic operations in page_counter_uncharge(). The corresponding call graph is below (provided by Imran Khan): |__alloc_skb | | | |__kmalloc_reserve.isra.61 | | | | | |__kmalloc_node_track_caller | | | | | | | |slab_pre_alloc_hook.constprop.88 | | | obj_cgroup_charge | | | | | | | | | |__memcg_kmem_charge | | | | | | | | | | | |page_counter_try_charge | | | | | | | | | |refill_obj_stock | | | | | | | | | | | |drain_obj_stock.isra.68 | | | | | | | | | | | | | |__memcg_kmem_uncharge | | | | | | | | | | | | | | | |page_counter_uncharge | | | | | | | | | | | | | | | | | |page_counter_cancel | | | | | | | | | | | |__slab_alloc | | | | | | | | | |___slab_alloc | | | | | | | | |slab_post_alloc_hook Instead of directly uncharging the accounted kernel memory, it's possible to refill the generic page-sized per-cpu stock instead. It's a much faster operation, especially on a default hierarchy. As a bonus, __memcg_kmem_uncharge_page() will also get faster, so the freeing of page-sized kernel allocations (e.g. large kmallocs) will become faster. A similar change has been done earlier for the socket memory by the commit 475d0487a2ad ("mm: memcontrol: use per-cpu stocks for socket memory uncharging").

2021-01-24mm: fix initialization of struct page for holes in memory layoutMike Rapoport1-34/+50
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.

2021-01-24x86/setup: don't remove E820_TYPE_RAM for pfn 0Mike Rapoport1-11/+9
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-foundation.org 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.

RHBZ 1848178 The original intent of returning an error in this function in the patch: "CIFS: Mask off signals when sending SMB packets" was to avoid interrupting packet send in the middle of sending the data (and thus breaking an SMB connection), but we also don't want to fail the request for non-fatal signals even before we have had a chance to try to send it (the reported problem could be reproduced e.g. by exiting a child process when the parent process was in the midst of calling futimens to update a file's timestamps). In addition, since the signal may remain pending when we enter the sending loop, we may end up not sending the whole packet before TCP buffers become full. In this case the code returns -EINTR but what we need here is to return -ERESTARTSYS instead to allow system calls to be restarted.

Use of crypto as a means to prevent malicious corruption requires further changes and was never a design goal for dm-integrity's primary usecase of detecting accidental corruption. - Fix a benign dm-crypt copy-and-paste bug introduced as part of a fix that was merged for 5.11-rc4. - Fix DM core's dm_get_device() to avoid filesystem lookup to get block device (if possible). * tag 'for-5.11/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm: avoid filesystem lookup in dm_get_dev_t() dm crypt: fix copy and paste bug in crypt_alloc_req_aead dm integrity: conditionally disable "recalculate" feature dm integrity: fix a crash if "recalculate" used without "internal_hash"
