27730c8 | Kan Liang | 29 September 2021, 15:38:13 UTC | perf script: Fix PERF_SAMPLE_WEIGHT_STRUCT support -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 <jmario@redhat.com> Reviewed-by: Kajol Jain <kjain@linux.ibm.com> Signed-off-by: Kan Liang <kan.liang@linux.intel.com> Tested-by: Jiri Olsa <jolsa@redhat.com> Tested-by: Joe Mario <jmario@redhat.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Acked-by: Joe Mario <jmario@redhat.com> Cc: Andi Kleen <ak@linux.intel.com> Link: https://lore.kernel.org/r/1632929894-102778-1-git-send-email-kan.liang@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> | 31 October 2021, 15:51:41 UTC |

29c7755 | Song Liu | 04 October 2021, 05:32:38 UTC | perf script: Check session->header.env.arch before using it 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.

09d9e4d | Avri Altman | 30 October 2021, 06:23:01 UTC | scsi: ufs: ufshpb: Remove HPB2.0 flows 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.

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.

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.

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."

337546e | Suren Baghdasaryan | 28 October 2021, 21:36:14 UTC | mm/oom_kill.c: prevent a race between process_mrelease and exit_mmap 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.

eac96c3 | Yang Shi | 28 October 2021, 21:36:11 UTC | mm: filemap: check if THP has hwpoisoned subpage for PMD page fault 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.

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.

e77bcdd | Rakesh Babu | 27 October 2021, 17:32:33 UTC | octeontx2-af: Display all enabled PF VF rsrc_alloc entries. Currently, we are using a fixed buffer size of length 2048 to display rsrc_alloc output. As a result a maximum of 2048 characters of rsrc_alloc output is displayed, which may lead sometimes to display only partial output. This patch fixes this dependency on max limit of buffer size and displays all PF VF entries. Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12 characters to print the list of LFs of each block for a PF/VF. If the length of list of LFs of a block exceeds this fixed width then the list gets truncated and displays only a part of the list. This patch fixes this by using the maximum possible length of list of LFs among all blocks of all PFs and VFs entries as the width size.

f29da40 | Yufeng Mo | 27 October 2021, 12:11:44 UTC | net: hns3: change hclge/hclgevf workqueue to WQ_UNBOUND mode Currently, the workqueue of hclge/hclgevf is executed on the CPU that initiates scheduling requests by default. In stress scenarios, the CPU may be busy and workqueue scheduling is completed after a long period of time. To avoid this situation and implement proper scheduling, use the WQ_UNBOUND mode instead. In this way, the workqueue can be performed on a relatively idle CPU. Signed-off-by: Yufeng Mo <moyufeng@huawei.com> Signed-off-by: Guangbin Huang <huangguangbin2@huawei.com> Signed-off-by: David S.

3bda2e5 | Guangbin Huang | 27 October 2021, 12:11:43 UTC | net: hns3: fix pause config problem after autoneg disabled If a TP port is configured by follow steps: 1.ethtool -s ethx autoneg off speed 100 duplex full 2.ethtool -A ethx rx on tx on 3.ethtool -s ethx autoneg on(rx&tx negotiated pause results are off) 4.ethtool -s ethx autoneg off speed 100 duplex full In step 3, driver will set rx&tx pause parameters of hardware to off as pause parameters negotiated with link partner are off. After step 4, the "ethtool -a ethx" command shows both rx and tx pause parameters are on. However, pause parameters of hardware are still off and port has no flow control function actually. To fix this problem, if autoneg is disabled, driver uses its saved parameters to restore pause of hardware. If the speed is not changed in this case, there is no link state changed for phy, it will cause the pause parameter is not taken effect, so we need to force phy to go down and up.

e0c60d0 | Shin'ichiro Kawasaki | 26 October 2021, 06:01:15 UTC | block: Fix partition check for host-aware zoned block devices Commit a33df75c6328 ("block: use an xarray for disk->part_tbl") modified the method to check partition existence in host-aware zoned block devices from disk_has_partitions() helper function call to empty check of xarray disk->part_tbl. However, disk->part_tbl always has single entry for disk->part0 and never becomes empty. This resulted in the host-aware zoned devices always judged to have partitions, and it made the sysfs queue/zoned attribute to be "none" instead of "host-aware" regardless of partition existence in the devices. This also caused DEBUG_LOCKS_WARN_ON(lock->magic != lock) for sdkp->rev_mutex in scsi layer when the kernel detects host-aware zoned device. Since block layer handled the host-aware zoned devices as non- zoned devices, scsi layer did not have chance to initialize the mutex for zone revalidation. Therefore, the warning was triggered. To fix the issues, call the helper function disk_has_partitions() in place of disk->part_tbl empty check. Since the function was removed with the commit a33df75c6328, reimplement it to walk through entries in the xarray disk->part_tbl.

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.
