[PATCH OLK-6.6 V1] sched/fair: Prefer physical cores when migrating tasks
by Cheng Yu 30 Oct '25

30 Oct '25

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAJEHU -------------------------------- When cpu hyperthreading is enabled, one physical core can virtualize multiple logical cpus. Assume that physical core0 virtualizes two logical cpus, cpu0 and cpu1. Only when the load of cpu0 exceeds the set ratio to the capacity of cpu0, the task will be migrated to the cpu1, otherwise the task will not be migrated and the cpu0 will still be used. External impacts: 1) default config: CONFIG_SCHED_KEEP_ON_CORE=y 2) sysctl: /proc/sys/kernel/sched_util_ratio 3) sched features: KEEP_ON_CORE (default NO_KEEP_ON_CORE) Signed-off-by: Cheng Yu <serein.chengyu(a)huawei.com> --- arch/arm64/Kconfig | 1 + arch/arm64/configs/openeuler_defconfig | 1 + init/Kconfig | 19 ++++++++++ kernel/sched/fair.c | 48 +++++++++++++++++++++++++- kernel/sched/features.h | 4 +++ 5 files changed, 72 insertions(+), 1 deletion(-) diff --git a/arch/arm64/Kconfig b/arch/arm64/Kconfig index dec41d9fa054..8ad5692a460c 100644 --- a/arch/arm64/Kconfig +++ b/arch/arm64/Kconfig @@ -107,6 +107,7 @@ config ARM64 select ARCH_SUPPORTS_NUMA_BALANCING select ARCH_SUPPORTS_SCHED_PARAL select ARCH_SUPPORTS_SCHED_SOFT_QUOTA + select ARCH_SUPPORTS_SCHED_KEEP_ON_CORE select ARCH_SUPPORTS_PAGE_TABLE_CHECK select ARCH_SUPPORTS_PER_VMA_LOCK select ARCH_WANT_BATCHED_UNMAP_TLB_FLUSH diff --git a/arch/arm64/configs/openeuler_defconfig b/arch/arm64/configs/openeuler_defconfig index ce292ed39752..57dcf692d82e 100644 --- a/arch/arm64/configs/openeuler_defconfig +++ b/arch/arm64/configs/openeuler_defconfig @@ -211,6 +211,7 @@ CONFIG_NET_NS=y CONFIG_SCHED_STEAL=y CONFIG_SCHED_PARAL=y CONFIG_SCHED_SOFT_QUOTA=y +CONFIG_SCHED_KEEP_ON_CORE=y CONFIG_CHECKPOINT_RESTORE=y CONFIG_SCHED_AUTOGROUP=y CONFIG_RELAY=y diff --git a/init/Kconfig b/init/Kconfig index 2720083aaa17..2322830cb4ce 100644 --- a/init/Kconfig +++ b/init/Kconfig @@ -1192,6 +1192,25 @@ config SCHED_SOFT_QUOTA restrictions on the use of the CPU quota, such as some commercial scenarios that charge based on the use of CPU quota. +# +# For architectures that want to enable the support for SCHED_KEEP_ON_CORE +# +config ARCH_SUPPORTS_SCHED_KEEP_ON_CORE + bool + +config SCHED_KEEP_ON_CORE + bool "Prefer physical cores when migrating tasks" + depends on ARCH_SUPPORTS_SCHED_KEEP_ON_CORE + depends on SCHED_SMT + default n + help + When cpu hyperthreading is enabled, one physical core can virtualize + multiple logical cpus.

[PATCH OLK-6.6] netfilter: ipset: fix region locking in hash types
by Zhang Changzhong 30 Oct '25

30 Oct '25

From: Jozsef Kadlecsik <kadlec(a)netfilter.org> stable inclusion from stable-v6.6.91 commit a3dfec485401943e315c394c29afe2db8f9481d6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICBIZM CVE: CVE-2025-37997 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 8478a729c0462273188263136880480729e9efca ] Region locking introduced in v5.6-rc4 contained three macros to handle the region locks: ahash_bucket_start(), ahash_bucket_end() which gave back the start and end hash bucket values belonging to a given region lock and ahash_region() which should give back the region lock belonging to a given hash bucket. The latter was incorrect which can lead to a race condition between the garbage collector and adding new elements when a hash type of set is defined with timeouts.

[PATCH OLK-5.10] netfilter: ipset: fix region locking in hash types
by Zhang Changzhong 30 Oct '25

30 Oct '25

From: Jozsef Kadlecsik <kadlec(a)netfilter.org> stable inclusion from stable-v5.10.238 commit 226ce0ec38316d9e3739e73a64b6b8304646c658 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICBIZM CVE: CVE-2025-37997 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 8478a729c0462273188263136880480729e9efca ] Region locking introduced in v5.6-rc4 contained three macros to handle the region locks: ahash_bucket_start(), ahash_bucket_end() which gave back the start and end hash bucket values belonging to a given region lock and ahash_region() which should give back the region lock belonging to a given hash bucket. The latter was incorrect which can lead to a race condition between the garbage collector and adding new elements when a hash type of set is defined with timeouts.
