2021-11-01RDMA/irdma: optimize rx path by removing unnecessary copyZhu Yanjun3-64/+39
In the function irdma_post_recv, the function irdma_copy_sg_list is not needed since the struct irdma_sge and ib_sge have the similar member variables. The struct irdma_sge can be replaced with the struct ib_sge totally. This can increase the rx performance of irdma.

2021-10-31perf script: Fix PERF_SAMPLE_WEIGHT_STRUCT supportKan Liang1-1/+1
-F weight in perf script is broken. # ./perf mem record # ./perf script -F weight Samples for 'dummy:HG' event do not have WEIGHT attribute set. Cannot print 'weight' field. The sample type, PERF_SAMPLE_WEIGHT_STRUCT, is an alternative of the PERF_SAMPLE_WEIGHT sample type. They share the same space, weight. The lower 32 bits are exactly the same for both sample type. The higher 32 bits may be different for different architecture. For a new kernel on x86, the PERF_SAMPLE_WEIGHT_STRUCT is used. For an old kernel or other ARCHs, the PERF_SAMPLE_WEIGHT is used. With -F weight, current perf script will only check the input string "weight" with the PERF_SAMPLE_WEIGHT sample type. Because the commit ea8d0ed6eae3 ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT") didn't update the PERF_SAMPLE_WEIGHT_STRUCT sample type for perf script. For a new kernel on x86, the check fails. Use PERF_SAMPLE_WEIGHT_TYPE, which supports both sample types, to replace PERF_SAMPLE_WEIGHT Fixes: ea8d0ed6eae37b01 ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT") Reported-by: Joe Mario <[email protected]> Reviewed-by: Kajol Jain <[email protected]> Signed-off-by: Kan Liang <[email protected]> Tested-by: Jiri Olsa <[email protected]> Tested-by: Joe Mario <[email protected]> Acked-by: Jiri Olsa <[email protected]> Acked-by: Joe Mario <[email protected]> Cc: Andi Kleen <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>

2021-10-31perf script: Check session->header.env.arch before using itSong Liu1-4/+8
When perf.data is not written cleanly, we would like to process existing data as much as possible (please see f_header.data.size == 0 condition in perf_session__read_header). However, perf.data with partial data may crash perf. Specifically, we see crash in 'perf script' for NULL session->header.env.arch. Fix this by checking session->header.env.arch before using it to determine native_arch. Also split the if condition so it is easier to read. Committer notes: If it is a pipe, we already assume is a native arch, so no need to check session->header.env.arch.

2021-10-30scsi: ufs: ufshpb: Remove HPB2.0 flowsAvri Altman3-288/+4
The Host Performance Buffer feature allows UFS read commands to carry the physical media addresses along with the LBAs, thus allowing less internal L2P-table switches in the device. HPB1.0 allowed a single LBA, while HPB2.0 increases this capacity up to 255 blocks. Carrying more than a single record, the read operation is no longer purely of type "read" but a "hybrid" command: Writing the physical address to the device in one operation and reading back the required payload in another. The JEDEC HPB spec defines two commands for this operation: HPB-WRITE-BUFFER (0x2) to write the physical addresses to device, and HPB-READ to read the payload. With the current HPB design the UFS driver has no alternative but to divide the READ request into 2 separate commands: HPB-WRITE-BUFFER and HPB-READ. This causes a great deal of aggravation to the block layer guys who demanded that we completely revert the entire HPB driver regardless of the huge amount of corporate effort already invested in it. As a compromise, remove only the pieces that implement the 2.0 specification. This is done as a matter of urgency for the final 5.15 release.

2021-10-29scsi: mpt3sas: Fix reference tag handling for WRITE_INSERTMartin K. Petersen1-3/+6
Testing revealed a problem with how the reference tag was handled for a WRITE_INSERT operation. The SCSI_PROT_REF_CHECK flag is not set when the controller is asked to generate the protection information (i.e. not DIX). And as a result the initial reference tag would not be set in the WRITE_INSERT case. Separate handling of the REF_CHECK and REF_INCREMENT flags to align with both the DIX spec and the MPI implementation.

It's a regression introduced in 5.15-rc and I'd really like not let this into the final release, fixes via stable trees would add unnecessary delay.

The pages that don't come from local allocation still may be from highmem. Despite being on 32bit there's enough such ARM machines in use so it's not a marginal issue. I did full reverts of the patches one by one instead of a huge one. There's one exception for the "lzo" revert as there was an intermediate patch touching the same code to make it compatible with subpage. I can't revert that one too, so the revert in lzo.c is manual.

2021-10-29riscv: Do not re-populate shadow memory with kasan_populate_early_shadowAlexandre Ghiti1-11/+0
When calling this function, all the shadow memory is already populated with kasan_early_shadow_pte which has PAGE_KERNEL protection. kasan_populate_early_shadow write-protects the mapping of the range of addresses passed in argument in zero_pte_populate, which actually write-protects all the shadow memory mapping since kasan_early_shadow_pte is used for all the shadow memory at this point. And then when using memblock API to populate the shadow memory, the first write access to the kernel stack triggers a trap. This becomes visible with the next commit that contains a fix for asan-stack. We already manually populate all the shadow memory in kasan_early_init and we write-protect kasan_early_shadow_pte at the end of kasan_init which makes the calls to kasan_populate_early_shadow superfluous so we can remove them.

This reverts commit 8c945d32e60427cbc0859cf7045bbe6196bb03d8. The kmaps in compression code are still needed and cause crashes on 32bit machines (ARM, x86). Reproducible eg. by running fstest btrfs/004 with enabled LZO or ZSTD compression. The revert does not apply cleanly due to changes in a6e66e6f8c1b ("btrfs: rework lzo_decompress_bio() to make it subpage compatible") that reworked the page iteration so the revert is done to be equivalent to the original code.

2021-10-28mm: khugepaged: skip huge page collapse for special filesYang Shi1-8/+11
The read-only THP for filesystems will collapse THP for files opened readonly and mapped with VM_EXEC. The intended usecase is to avoid TLB misses for large text segments. But it doesn't restrict the file types so a THP could be collapsed for a non-regular file, for example, block device, if it is opened readonly and mapped with EXEC permission. This may cause bugs, like [1] and [2]. This is definitely not the intended usecase, so just collapse THP for regular files in order to close the attack surface.

2021-10-28mm, thp: bail out early in collapse_file for writeback pageRongwei Wang1-1/+6
Currently collapse_file does not explicitly check PG_writeback, instead, page_has_private and try_to_release_page are used to filter writeback pages. This does not work for xfs with blocksize equal to or larger than pagesize, because in such case xfs has no page->private. This makes collapse_file bail out early for writeback page.

Eric Dumazet reported a strange numa spreading info in [1], and found commit 121e6f3258fe ("mm/vmalloc: hugepage vmalloc mappings") introduced this issue [2]. Dig into the difference before and after this patch, page allocation has some difference: before: alloc_large_system_hash __vmalloc __vmalloc_node(..., NUMA_NO_NODE, ...) __vmalloc_node_range __vmalloc_area_node alloc_page /* because NUMA_NO_NODE, so choose alloc_page branch */ alloc_pages_current alloc_page_interleave /* can be proved by print policy mode */ after: alloc_large_system_hash __vmalloc __vmalloc_node(..., NUMA_NO_NODE, ...) __vmalloc_node_range __vmalloc_area_node alloc_pages_node /* choose nid by nuam_mem_id() */ __alloc_pages_node(nid, ....) So after commit 121e6f3258fe ("mm/vmalloc: hugepage vmalloc mappings"), it will allocate memory in current node instead of interleaving allocate memory.

2021-10-28mm/secretmem: avoid letting secretmem_users drop to zeroKees Cook1-1/+1
Quoting Dmitry: "refcount_inc() needs to be done before fd_install(). After fd_install() finishes, the fd can be used by userspace and we can have secret data in memory before the refcount_inc(). A straightforward misuse where a user will predict the returned fd in another thread before the syscall returns and will use it to store secret data is somewhat dubious because such a user just shoots themself in the foot. But a more interesting misuse would be to close the predicted fd and decrement the refcount before the corresponding refcount_inc, this way one can briefly drop the refcount to zero while there are other users of secretmem." Move fd_install() after refcount_inc().

2021-10-28mm/oom_kill.c: prevent a race between process_mrelease and exit_mmapSuren Baghdasaryan1-11/+12
Race between process_mrelease and exit_mmap, where free_pgtables is called while __oom_reap_task_mm is in progress, leads to kernel crash during pte_offset_map_lock call. oom-reaper avoids this race by setting MMF_OOM_VICTIM flag and causing exit_mmap to take and release mmap_write_lock, blocking it until oom-reaper releases mmap_read_lock. Reusing MMF_OOM_VICTIM for process_mrelease would be the simplest way to fix this race, however that would be considered a hack. Fix this race by elevating mm->mm_users and preventing exit_mmap from executing until process_mrelease is finished. Patch slightly refactors the code to adapt for a possible mmget_not_zero failure. This fix has considerable negative impact on process_mrelease performance and will likely need later optimization.

2021-10-28mm: filemap: check if THP has hwpoisoned subpage for PMD page faultYang Shi5-1/+51
When handling shmem page fault the THP with corrupted subpage could be PMD mapped if certain conditions are satisfied. But kernel is supposed to send SIGBUS when trying to map hwpoisoned page. There are two paths which may do PMD map: fault around and regular fault. Before commit f9ce0be71d1f ("mm: Cleanup faultaround and finish_fault() codepaths") the thing was even worse in fault around path. The THP could be PMD mapped as long as the VMA fits regardless what subpage is accessed and corrupted. After this commit as long as head page is not corrupted the THP could be PMD mapped. In the regular fault path the THP could be PMD mapped as long as the corrupted page is not accessed and the VMA fits. This loophole could be fixed by iterating every subpage to check if any of them is hwpoisoned or not, but it is somewhat costly in page fault path. So introduce a new page flag called HasHWPoisoned on the first tail page. It indicates the THP has hwpoisoned subpage(s). It is set if any subpage of THP is found hwpoisoned by memory failure and after the refcount is bumped successfully, then cleared when the THP is freed or split. The soft offline path doesn't need this since soft offline handler just marks a subpage hwpoisoned when the subpage is migrated successfully. But shmem THP didn't get split then migrated at all.

2021-10-28mm: hwpoison: remove the unnecessary THP checkYang Shi1-14/+0
When handling THP hwpoison checked if the THP is in allocation or free stage since hwpoison may mistreat it as hugetlb page. After commit 415c64c1453a ("mm/memory-failure: split thp earlier in memory error handling") the problem has been fixed, so this check is no longer needed. Remove it. The side effect of the removal is hwpoison may report unsplit THP instead of unknown error for shmem THP. It seems not like a big deal. The following patch "mm: filemap: check if THP has hwpoisoned subpage for PMD page fault" depends on this, which fixes shmem THP with hwpoisoned subpage(s) are mapped PMD wrongly. So this patch needs to be backported to -stable as well.

2021-10-28memcg: page_alloc: skip bulk allocator for __GFP_ACCOUNTShakeel Butt1-0/+4
Commit 5c1f4e690eec ("mm/vmalloc: switch to bulk allocator in __vmalloc_area_node()") switched to bulk page allocator for order 0 allocation backing vmalloc. However bulk page allocator does not support __GFP_ACCOUNT allocations and there are several users of kvmalloc(__GFP_ACCOUNT). For now make __GFP_ACCOUNT allocations bypass bulk page allocator. In future if there is workload that can be significantly improved with the bulk page allocator with __GFP_ACCCOUNT support, we can revisit the decision.
