[PATCH v7 OLK-5.10 0/3] arm64: support page mapping percpu first chunk allocator
by Kaixiong Yu 13 Nov '24

13 Nov '24

Percpu embedded first chunk allocator is the firstly option, but it could fails on ARM64 when turning on numa with CONFIG_KASAN=y. Let's implement page mapping percpu first chunk allocator as a fallback to the embedding allocator to increase the robustness of the system. Also fix a crash when both NEED_PER_CPU_PAGE_FIRST_CHUNK and KASAN_VMALLOC enabled. After merging this patch set, the ARM64 machine can start and work normally.

Ensure that direct file execution (e.g. ./script.sh) and indirect file execution (e.g. sh script.sh) lead to the same result to support script protection. Gu Bowen (2): IMA support script execution check fix kabi breakage due to exec is_check Kees Cook (1): exec: Check __FMODE_EXEC instead of in_execve for LSMs Linus Torvalds (2): execve: open the executable file before doing anything else uselib: remove use of __FMODE_EXEC Mickaël Salaün (1): exec: Add a new AT_CHECK flag to execveat(2) V2: Add a new patch to fix kabi breakage. Align with the original variables to prevent others from inserting new variables before is_check in the future. V3: Add a mainline patch to fix commit 4759ff71f23e(exec: __FMODE_EXEC instead of in_execve for LSMs). V4: Since openEuler has a more standardised way of using KABI_FILL_HOLE to fix kabi breakage, replace it. fs/exec.c | 89 ++++++++++++++++++------------- include/linux/binfmts.h | 5 ++ include/linux/ima.h | 1 + include/uapi/linux/fcntl.h | 31 +++++++++++ kernel/audit.h | 1 + kernel/auditsc.c | 1 + security/apparmor/lsm.c | 4 +- security/integrity/ima/ima_main.c | 11 ++++ security/security.c | 17 +++++- security/tomoyo/tomoyo.c | 3 +- 10 files changed, 123 insertions(+), 40 deletions(-) -- 2.25.1

[PATCH openEuler-1.0-LTS] irqchip/i8259: Fix shutdown order by moving syscore_ops registration
by Zhang Kunbo 13 Nov '24

13 Nov '24

From: Aaro Koskinen <aaro.koskinen(a)iki.fi> mainline inclusion from mainline-v5.1-rc1 commit 518bfe84ec417318b2470652cdb27978ddfeaa59 category: bugfix bugzilla: 190379 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When using cpufreq on Loongson 2F MIPS platform, "poweroff" command gets frequently stuck in syscore_shutdown(). The reason is that i8259A_shutdown() gets called before cpufreq_suspend(), and if we have pending work then irq_work_sync() in cpufreq_dbs_governor_stop() gets stuck forever as we have all interrupts masked already. irq-i8259 is registering syscore_ops using device_initcall(), while cpufreq uses core_initcall(). Fix the shutdown order simply by registering the irq syscore_ops during the early IRQ init instead of using a separate initcall at later stage.

[PATCH OLK-6.6 0/6] Script execution control
by Gu Bowen 13 Nov '24

13 Nov '24

Ensure that direct file execution (e.g. ./script.sh) and indirect file execution (e.g. sh script.sh) lead to the same result to support script protection. Gu Bowen (2): IMA support script execution check fix kabi breakage due to exec is_check Kees Cook (1): exec: Check __FMODE_EXEC instead of in_execve for LSMs Linus Torvalds (2): execve: open the executable file before doing anything else uselib: remove use of __FMODE_EXEC Mickaël Salaün (1): exec: Add a new AT_CHECK flag to execveat(2) V2: Add a new patch to fix kabi breakage. Align with the original variables to prevent others from inserting new variables before is_check in the future. V3: Add a mainline patch to fix commit 4759ff71f23e(exec: __FMODE_EXEC instead of in_execve for LSMs). V4: Since openEuler has a more standardised way of using KABI_FILL_HOLE to fix kabi breakage, replace it. fs/exec.c | 89 ++++++++++++++++++------------- include/linux/binfmts.h | 5 ++ include/linux/ima.h | 1 + include/uapi/linux/fcntl.h | 31 +++++++++++ kernel/audit.h | 1 + kernel/auditsc.c | 1 + security/apparmor/lsm.c | 4 +- security/integrity/ima/ima_main.c | 11 ++++ security/security.c | 17 +++++- security/tomoyo/tomoyo.c | 3 +- 10 files changed, 123 insertions(+), 40 deletions(-) -- 2.25.1
