[to-be-updated] x86-kexec-fix-potential-cmem-ranges-out-of-bounds.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: x86/kexec: fix potential cmem->ranges out of bounds has been removed from the -mm tree. Its filename was x86-kexec-fix-potential-cmem-ranges-out-of-bounds.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: fuqiang wang <fuqiang.wang(a)easystack.cn> Subject: x86/kexec: fix potential cmem->ranges out of bounds Date: Mon, 8 Jan 2024 21:06:47 +0800 In memmap_exclude_ranges(), elfheader will be excluded from crashk_res. In the current x86 architecture code, the elfheader is always allocated at crashk_res.start. It seems that there won't be a new split range. But it depends on the allocation position of elfheader in crashk_res. To avoid potential out of bounds in future, add a extra slot. The similar issue also exists in fill_up_crash_elf_data(). The range to be excluded is [0, 1M], start (0) is special and will not appear in the middle of existing cmem->ranges[]. But in cast the low 1M could be changed in the future, add a extra slot too.

[PATCH 1/2] iio: Fix scan mask subset check logic

by Fabio Estevam

From: Fabio Estevam <festevam(a)denx.de> Since commit 2718f15403fb ("iio: sanity check available_scan_masks array"), verbose and misleading warnings are printed for devices like the MAX11601: max1363 1-0064: available_scan_mask 8 subset of 0. Never used max1363 1-0064: available_scan_mask 9 subset of 0. Never used max1363 1-0064: available_scan_mask 10 subset of 0. Never used max1363 1-0064: available_scan_mask 11 subset of 0. Never used max1363 1-0064: available_scan_mask 12 subset of 0. Never used max1363 1-0064: available_scan_mask 13 subset of 0. Never used ... [warnings continue] Fix the available_scan_masks sanity check logic so that it only prints the warning when an element of available_scan_mask is in fact a subset of a previous one. These warnings incorrectly report that later scan masks are subsets of the first one, even when they are not. The issue lies in the logic that checks for subset relationships between scan masks. Fix the subset detection to correctly compare each mask only against previous masks, and only warn when a true subset is found. With this fix, the warning output becomes both correct and more informative: max1363 1-0064: Mask 7 (0xc) is a subset of mask 6 (0xf) and will be ignored Cc: stable(a)vger.kernel.org Fixes: 2718f15403fb ("iio: sanity check available_scan_masks array") Signed-off-by: Fabio Estevam <festevam(a)denx.de> --- drivers/iio/industrialio-core.c | 23 ++++++++++------------- 1 file changed, 10 insertions(+), 13 deletions(-) diff --git a/drivers/iio/industrialio-core.c b/drivers/iio/industrialio-core.c index 6a6568d4a2cb..855d5fd3e6b2 100644 --- a/drivers/iio/industrialio-core.c +++ b/drivers/iio/industrialio-core.c @@ -1904,6 +1904,11 @@ static int iio_check_extended_name(const struct iio_dev *indio_dev) static const struct iio_buffer_setup_ops noop_ring_setup_ops; +static int is_subset(unsigned long a, unsigned long b) +{ + return (a & ~b) == 0; +} + static void iio_sanity_check_avail_scan_masks(struct iio_dev *indio_dev) { unsigned int num_masks, masklength, longs_per_mask; @@ -1947,21 +1952,13 @@ static void iio_sanity_check_avail_scan_masks(struct iio_dev *indio_dev) * available masks in the order of preference (presumably the least * costy to access masks first). */ - for (i = 0; i < num_masks - 1; i++) { - const unsigned long *mask1; - int j; - mask1 = av_masks + i * longs_per_mask; - for (j = i + 1; j < num_masks; j++) { - const unsigned long *mask2; - - mask2 = av_masks + j * longs_per_mask; - if (bitmap_subset(mask2, mask1, masklength)) + for (i = 1; i < num_masks; ++i) + for (int j = 0; j < i; ++j) + if (is_subset(av_masks[i], av_masks[j])) dev_warn(indio_dev->dev.parent, - "available_scan_mask %d subset of %d.

[PATCH v2] drm/bridge: cdns-dsi: Replace deprecated UNIVERSAL_DEV_PM_OPS()

by Vitor Soares

From: Vitor Soares <vitor.soares(a)toradex.com> The deprecated UNIVERSAL_DEV_PM_OPS() macro uses the provided callbacks for both runtime PM and system sleep.

[PATCH] ACPI: PPTT: Fix processor subtable walk

by Jeremy Linton

The original PPTT code had a bug where the processor subtable length was not correctly validated when encountering a truncated acpi_pptt_processor node. Commit 7ab4f0e37a0f4 ("ACPI PPTT: Fix coding mistakes in a couple of sizeof() calls") attempted to fix this by validating the size is as large as the acpi_pptt_processor node structure. This introduced a regression where the last processor node in the PPTT table is ignored if it doesn't contain any private resources. That results errors like: ACPI PPTT: PPTT table found, but unable to locate core XX (XX) ACPI: SPE must be homogeneous Furthermore, it fail in a common case where the node length isn't equal to the acpi_pptt_processor structure size, leaving the original bug in a modified form. Correct the regression by adjusting the loop termination conditions as suggested by the bug reporters. An additional check performed after the subtable node type is detected, validates the acpi_pptt_processor node is fully contained in the PPTT table. Repeating the check in acpi_pptt_leaf_node() is largely redundant as the node is already known to be fully contained in the table. The case where a final truncated node's parent property is accepted, but the node itself is rejected should not be considered a bug.
