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.

On configs with CONFIG_HAVE_ARCH_USERFAULTFD_MINOR=y (selected by CONFIG_ARM64 when CONFIG_USERFAULTFD=y), VM_UFFD_MINOR is _also_ bit 38. This bit being shared by two different VMA flags could lead to all sorts of unintended behaviors. Presumably, a process could maybe call into userfaultfd in a way that disables the shadow stack vma flag. I can't think of any attack where this would help (presumably, if an attacker tries to disable shadow stacks, they are trying to hijack control flow so can't arbitrarily call into userfaultfd yet anyway) but this still feels somewhat scary.

This is also done if CONFIG_TRANSPARENT_HUGEPAGE is not defined. But in that case, the VM_NOHUGEPAGE does not make sense. I discovered this issue when trying to use the tool CRIU to checkpoint and restore a container. Our running kernel is compiled without CONFIG_TRANSPARENT_HUGEPAGE. CRIU parses the output of /proc/<pid>/smaps and saves the "nh" flag. When trying to restore the container, CRIU fails to restore the "nh" mappings, since madvise() MADV_NOHUGEPAGE always returns an error because CONFIG_TRANSPARENT_HUGEPAGE is not defined.

Borislav and Thomas pointed out that the tracking is racy: operations on static_branch are not serialized against adding/removing unaccepted pages to/from the zone. Sanity checks inside static_branch machinery detects it: WARNING: CPU: 0 PID: 10 at kernel/jump_label.c:276 __static_key_slow_dec_cpuslocked+0x8e/0xa0 The comment around the WARN() explains the problem: /* * Warn about the '-1' case though; since that means a * decrement is concurrent with a first (0->1) increment.

[PATCH net] net: qede: Initialize qede_ll_ops with designated initializer

by Nathan Chancellor

After a recent change [1] in clang's randstruct implementation to randomize structures that only contain function pointers, there is an error because qede_ll_ops get randomized but does not use a designated initializer for the first member: drivers/net/ethernet/qlogic/qede/qede_main.c:206:2: error: a randomized struct can only be initialized with a designated initializer 206 | { | ^ Explicitly initialize the common member using a designated initializer to fix the build.

[PATCH v3 3/3] media: omap3isp: use sgtable-based scatterlist wrappers

by Marek Szyprowski

Use common wrappers operating directly on the struct sg_table objects to fix incorrect use of scatterlists sync calls. dma_sync_sg_for_*() functions have to be called with the number of elements originally passed to dma_map_sg_*() function, not the one returned in sgtable's nents.

[PATCH] ACPI/PPTT: fix off-by-one error

by Heyne, Maximilian

Commit 7ab4f0e37a0f ("ACPI PPTT: Fix coding mistakes in a couple of sizeof() calls") corrects the processer entry size but unmasked a longer standing bug where the last entry in the structure can get skipped due to an off-by-one mistake if the last entry ends exactly at the end of the ACPI subtable.

[PATCH v3] NFSD: Implement FATTR4_CLONE_BLKSIZE attribute

by cel＠kernel.org

From: Chuck Lever <chuck.lever(a)oracle.com> RFC 7862 states that if an NFS server implements a CLONE operation, it MUST also implement FATTR4_CLONE_BLKSIZE. NFSD implements CLONE, but does not implement FATTR4_CLONE_BLKSIZE. Note that in Section 12.2, RFC 7862 claims that FATTR4_CLONE_BLKSIZE is RECOMMENDED, not REQUIRED. Likely this is because a minor version is not permitted to add a REQUIRED attribute. Confusing. We assume this attribute reports a block size as a count of bytes, as RFC 7862 does not specify a unit.

[PATCH v2] drm/tegra: Assign plane type before registration

by Aaron Kling via B4 Relay

From: Thierry Reding <treding(a)nvidia.com> Changes to a plane's type after it has been registered aren't propagated to userspace automatically. This could possibly be achieved by updating the property, but since we can already determine which type this should be before the registration, passing in the right type from the start is a much better solution.
