[PATCH v5 01/16] x86/stackprotector: Work around strict Clang TLS symbol requirements

by Brian Gerst

From: Ard Biesheuvel <ardb(a)kernel.org> GCC and Clang both implement stack protector support based on Thread Local Storage (TLS) variables, and this is used in the kernel to implement per-task stack cookies, by copying a task's stack cookie into a per-CPU variable every time it is scheduled in. Both now also implement -mstack-protector-guard-symbol=, which permits the TLS variable to be specified directly. This is useful because it will allow us to move away from using a fixed offset of 40 bytes into the per-CPU area on x86_64, which requires a lot of special handling in the per-CPU code and the runtime relocation code. However, while GCC is rather lax in its implementation of this command line option, Clang actually requires that the provided symbol name refers to a TLS variable (i.e., one declared with __thread), although it also permits the variable to be undeclared entirely, in which case it will use an implicit declaration of the right type. The upshot of this is that Clang will emit the correct references to the stack cookie variable in most cases, e.g., 10d: 64 a1 00 00 00 00 mov %fs:0x0,%eax 10f: R_386_32 __stack_chk_guard However, if a non-TLS definition of the symbol in question is visible in the same compilation unit (which amounts to the whole of vmlinux if LTO is enabled), it will drop the per-CPU prefix and emit a load from a bogus address. Work around this by using a symbol name that never occurs in C code, and emit it as an alias in the linker script.

[PATCH 5.10 1/1] ASoC: ops: Check for negative values before reading them

by d.privalov

From: Mark Brown <broonie(a)kernel.org> commit 1601033da2dd2052e0489137f7788a46a8fcd82f upstream. The controls allow inputs to be specified as negative but our manipulating them into register fields need to be done on unsigned variables so the checks for negative numbers weren't taking effect properly. Do the checks for negative values on the variable in the ABI struct rather than on our local unsigned copy.

[PATCH v3 1/2] PCI: Fix wrong length of devres array

by Philipp Stanner

The array for the iomapping cookie addresses has a length of PCI_STD_NUM_BARS. This constant, however, only describes standard BARs; while PCI can allow for additional, special BARs. The total number of PCI resources is described by constant PCI_NUM_RESOURCES, which is also used in, e.g., pci_select_bars(). Thus, the devres array has so far been too small. Change the length of the devres array to PCI_NUM_RESOURCES.

[PATCH 07/11] drm/amd/display: Use HW lock mgr for PSR1 when only one eDP

by Alex Hung

From: Mario Limonciello <mario.limonciello(a)amd.com> [WHY] DMUB locking is important to make sure that registers aren't accessed while in PSR. Previously it was enabled but caused a deadlock in situations with multiple eDP panels. [HOW] Detect if multiple eDP panels are in use to decide whether to use lock. Refactor the function so that the first check is for PSR-SU and then replay is in use to prevent having to look up number of eDP panels for those configurations.

[PATCH] mm: introduce include/linux/pgalloc.h

by Gwan-gyeong Mun

The include/linux/pgalloc.h is going to be the home of generic page table population functions. Start with including asm/pgalloc.h to include/linux/pgalloc.h and adding functions that if an architecture needs to synchronize global pgds when populating the init_mm's pgd. The newly introduced p4d_populate_kernel() and pgd_populate_kernel() functions synchronize global pgds after populating init_mm's p4d/pgd. If the architecture requires to synchronize global pgds, add ARCH_USE_SYNC_GLOBAL_PGDS to the Kconfig of the required architecture and implement arch_sync_global_p4ds() and arch_sync_global_pgds() to the architecture. And this patch adds an implementation to the x86 architecture. Through using new introduced p4d_populate_kernel() and pgd_populate_kernel() functions, it addresses an Oops issues when performing test of loading XE GPU driver module after applying the GPU SVM and Xe SVM patch series[1] and the Dept patch series[2]. The issue occurs when loading the xe driver via modprobe [3], which adds a struct page for device memory via devm_memremap_pages(). When a process leads the addition of a struct page to vmemmap (e.g. hot-plug), the page table update for the newly added vmemmap-based virtual address is updated first in init_mm's page table and then synchronized later. If the vmemmap-based virtual address is accessed through the process's page table before this sync, a page fault will occur. This addresses the issue by synchronizing with the global pgds immediately after populating the init_mm's pgd.

Until then, all watermarks are set to zero. This causes cond_accept_memory() to incorrectly skip memory acceptance because a watermark of 0 is always met. This can lead to a premature OOM on boot. To ensure progress, accept one MAX_ORDER page if the watermark is zero.

[PATCH] kbuild: deb-pkg: don't set KBUILD_BUILD_VERSION indiscriminately

by Alexandru Gagniuc

In ThinPro, we use the convention <upstream_ver>+hp<patchlevel> for the kernel package. This does not have a dash in the name or version. This is built by editing ".version" before a build, and setting EXTRAVERSION="+hp" and KDEB_PKGVERSION make variables: echo 68 > .version make -j<n> EXTRAVERSION="+hp" bindeb-pkg KDEB_PKGVERSION=6.6.6+hp69 .deb name: linux-image-6.6.6+hp_6.6.6+hp69_amd64.deb Since commit 7d4f07d5cb71 ("kbuild: deb-pkg: squash scripts/package/deb-build-option to debian/rules"), this no longer works. The deb build logic changed, even though, the commit message implies that the logic should be unmodified. Before, KBUILD_BUILD_VERSION was not set if the KDEB_PKGVERSION did not contain a dash. After the change KBUILD_BUILD_VERSION is always set to KDEB_PKGVERSION. Since this determines UTS_VERSION,the uname output to look off: (now) uname -a: version 6.6.6+hp ... #6.6.6+hp69 (expected) uname -a: version 6.6.6+hp ... #69 Update the debian/rules logic to restore the original behavior.

[PATCH] memcg: drain obj stock on cpu hotplug teardown

by Shakeel Butt

Currently on cpu hotplug teardown, only memcg stock is drained but we need to drain the obj stock as well otherwise we will miss the stats accumulated on the target cpu as well as the nr_bytes cached. The stats include MEMCG_KMEM, NR_SLAB_RECLAIMABLE_B & NR_SLAB_UNRECLAIMABLE_B. In addition we are leaking reference to struct obj_cgroup object.
