[PATCH] ACPI: APEI: set memory failure flags as MF_ACTION_REQUIRED on action required events

by Shuai Xue

There are two major types of uncorrected error (UC) : - Action Required: The error is detected and the processor already consumes the memory. OS requires to take action (for example, offline failure page/kill failure thread) to recover this uncorrectable error. - Action Optional: The error is detected out of processor execution context. Some data in the memory are corrupted. But the data have not been consumed. OS is optional to take action to recover this uncorrectable error. For X86 platforms, we can easily distinguish between these two types based on the MCA Bank. While for arm64 platform, the memory failure flags for all UCs which severity are GHES_SEV_RECOVERABLE are set as 0, a.k.a, Action Optional now. If UC is detected by a background scrubber, it is obviously an Action Optional error. For other errors, we should conservatively regard them as Action Required. cper_sec_mem_err::error_type identifies the type of error that occurred if CPER_MEM_VALID_ERROR_TYPE is set. So, set memory failure flags as 0 for Scrub Uncorrected Error (type 14). Otherwise, set memory failure flags as MF_ACTION_REQUIRED.

[RFT 1/2] RISC-V: handle missing "no-map" properties for OpenSBI's PMP protected regions

by Conor Dooley

Add an erratum for versions [v0.8 to v1.3) of OpenSBI which fail to add the "no-map" property to the reserved memory nodes for the regions it has protected using PMPs. Our existing fix sweeping hibernation under the carpet by marking it NONPORTABLE is insufficient as there are other ways to generate accesses to these reserved memory regions, as Petr discovered [1] while testing crash kernels & kdump. Intercede during the boot process when the afflicted versions of OpenSBI are present & set the "no-map" property in all "mmode_resv" nodes before the kernel does its reserved memory region initialisation.

[PATCH v2 1/6] PCI/ASPM: Add locked helper for enabling link state

by Johan Hovold

Add a helper for enabling link states that can be used in contexts where a pci_bus_sem read lock is already held (e.g. from pci_walk_bus()). This helper will be used to fix a couple of potential deadlocks where the current helper is called with the lock already held, hence the CC stable tag.

[PATCH v5] block: add check that partition length needs to be aligned with block size

by Min Li

Before calling add partition or resize partition, there is no check on whether the length is aligned with the logical block size. If the logical block size of the disk is larger than 512 bytes, then the partition size maybe not the multiple of the logical block size, and when the last sector is read, bio_truncate() will adjust the bio size, resulting in an IO error if the size of the read command is smaller than the logical block size.If integrity data is supported, this will also result in a null pointer dereference when calling bio_integrity_free.

Changes from v2: - Add the assignment on the first line and merge the two lines into one. Changes from v3: - Change the blksz to unsigned int. - Add check if p.start and p.length are negative. Changes from v4: - Remove the local variable blksz and use bdev_logical_block_size(bdev) directly. --- block/ioctl.c | 11 +++++++---- 1 file changed, 7 insertions(+), 4 deletions(-) diff --git a/block/ioctl.c b/block/ioctl.c index 3be11941fb2d..0e8723c1a807 100644 --- a/block/ioctl.c +++ b/block/ioctl.c @@ -18,7 +18,7 @@ static int blkpg_do_ioctl(struct block_device *bdev, { struct gendisk *disk = bdev->bd_disk; struct blkpg_partition p; - long long start, length; + sector_t start, length; if (!capable(CAP_SYS_ADMIN)) return -EACCES; @@ -33,14 +33,17 @@ static int blkpg_do_ioctl(struct block_device *bdev, if (op == BLKPG_DEL_PARTITION) return bdev_del_partition(disk, p.pno); + if (p.start < 0 || p.length <= 0 || p.start + p.length < 0) + return -EINVAL; + /* Check that the partition is aligned to the block size */ + if (!IS_ALIGNED(p.start | p.length, bdev_logical_block_size(bdev))) + return -EINVAL; + start = p.start >> SECTOR_SHIFT; length = p.length >> SECTOR_SHIFT; switch (op) { case BLKPG_ADD_PARTITION: - /* check if partition is aligned to blocksize */ - if (p.start & (bdev_logical_block_size(bdev) - 1)) - return -EINVAL; return bdev_add_partition(disk, p.pno, start, length); case BLKPG_RESIZE_PARTITION: return bdev_resize_partition(disk, p.pno, start, length); -- 2.34.1
