[PATCH OLK-5.10] [Backport]net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()
by Zhenzeng Su 24 Apr '24

24 Apr '24

From: Rand Deeb <rand.sec96(a)gmail.com> stable inclusion from stable-v5.10.213 commit 37fe99016b12d32100ce670216816dba6c48b309 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9HK2H CVE: CVE-2024-26855 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 06e456a05d669ca30b224b8ed962421770c1496c ] The function ice_bridge_setlink() may encounter a NULL pointer dereference if nlmsg_find_attr() returns NULL and br_spec is dereferenced subsequently in nla_for_each_nested(). To address this issue, add a check to ensure that br_spec is not NULL before proceeding with the nested attribute iteration.

[PATCH V4 OLK-6.6] mm, fs: Add BPF_READAHEAD build option for bpf readhead
by ZhaoLong Wang 24 Apr '24

24 Apr '24

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7Y9JD CVE: NA --------------------------- This patch introduces a new configuration option called BPF_READAHEAD, which is designed to optimize the read performance in Spark SQL scenarios using eBPF to implement a programmable kernel. The changes include: - Add CONFIG_BPF_READAHEAD to mm/Kconfig, which depends on CONFIG_TRACEPOINTS. - Add conditional compilation directives to fs/ext4/file.c, fs/read_write.c, fs/xfs/xfs_file.c, and include/linux/fs.h to include tracepoint-related headers and functions only when BPF_READAHEAD is enabled. - Miodify page_cache_sync_ra() in mm/readahead.c to disable forced readahead when BPF_READAHEAD is not enabled. V2: Explicitly set CONFIG_ in openeuler_defconfig. Do not add redundant macros to mm/readahead. V3: Place all macro isolation switches in the .h header file. V4: Change the macro name BPF_READAHEAD_OPTIMIZATION to BPF_READAHEAD Signed-off-by: ZhaoLong Wang <wangzhaolong1(a)huawei.com> --- arch/arm64/configs/openeuler_defconfig | 1 + arch/powerpc/configs/openeuler_defconfig | 1 + arch/riscv/configs/openeuler_defconfig | 1 + arch/x86/configs/openeuler_defconfig | 1 + fs/read_write.c | 4 ++-- include/linux/fs.h | 18 +++++++++++++----- include/trace/events/fs.h | 6 ++++++ mm/Kconfig | 9 +++++++++ 8 files changed, 34 insertions(+), 7 deletions(-) diff --git a/arch/arm64/configs/openeuler_defconfig b/arch/arm64/configs/openeuler_defconfig index 9a6ef6175717..b8bdcf53c062 100644 --- a/arch/arm64/configs/openeuler_defconfig +++ b/arch/arm64/configs/openeuler_defconfig @@ -1192,6 +1192,7 @@ CONFIG_DYNAMIC_POOL=y CONFIG_ETMEM_SCAN=m CONFIG_ETMEM_SWAP=m CONFIG_ETMEM=y +# CONFIG_BPF_READAHEAD_OPTIMIZATION is not set # # Data Access Monitoring diff --git a/arch/powerpc/configs/openeuler_defconfig b/arch/powerpc/configs/openeuler_defconfig index 152b941da1d5..793cca85862c 100644 --- a/arch/powerpc/configs/openeuler_defconfig +++ b/arch/powerpc/configs/openeuler_defconfig @@ -860,6 +860,7 @@ CONFIG_ARCH_HAS_HUGEPD=y CONFIG_USERFAULTFD=y # CONFIG_LRU_GEN is not set CONFIG_LOCK_MM_AND_FIND_VMA=y +# CONFIG_BPF_READAHEAD_OPTIMIZATION is not set # # Data Access Monitoring diff --git a/arch/riscv/configs/openeuler_defconfig b/arch/riscv/configs/openeuler_defconfig index cb132f4576da..06caed7e855a 100644 --- a/arch/riscv/configs/openeuler_defconfig +++ b/arch/riscv/configs/openeuler_defconfig @@ -825,6 +825,7 @@ CONFIG_ARCH_SUPPORTS_PER_VMA_LOCK=y CONFIG_PER_VMA_LOCK=y CONFIG_LOCK_MM_AND_FIND_VMA=y # CONFIG_PAGE_CACHE_LIMIT is not set +# CONFIG_BPF_READAHEAD_OPTIMIZATION is not set # # Data Access Monitoring diff --git a/arch/x86/configs/openeuler_defconfig b/arch/x86/configs/openeuler_defconfig index 1d20beb4bb6d..3338dc1c7037 100644 --- a/arch/x86/configs/openeuler_defconfig +++ b/arch/x86/configs/openeuler_defconfig @@ -1179,6 +1179,7 @@ CONFIG_DYNAMIC_POOL=y CONFIG_ETMEM_SCAN=m CONFIG_ETMEM_SWAP=m CONFIG_ETMEM=y +# CONFIG_BPF_READAHEAD_OPTIMIZATION is not set # # Data Access Monitoring diff --git a/fs/read_write.c b/fs/read_write.c index 3d69fb284d10..265e40589be8 100644 --- a/fs/read_write.c +++ b/fs/read_write.c @@ -1721,7 +1721,7 @@ int generic_file_rw_checks(struct file *file_in, struct file *file_out) return 0; } -#ifdef CONFIG_TRACEPOINTS +#ifdef CONFIG_BPF_READAHEAD_OPTIMIZATION static void fs_file_read_ctx_init(struct fs_file_read_ctx *ctx, struct file *filp, loff_t pos) { @@ -1752,7 +1752,7 @@ void fs_file_read_update_args_by_trace(struct kiocb *iocb) filp->f_ctl_mode &= ~(ctx.clr_f_mode & FS_FILE_READ_MODE_MASK); } EXPORT_SYMBOL_GPL(fs_file_read_update_args_by_trace); -#endif EXPORT_TRACEPOINT_SYMBOL_GPL(fs_file_read); EXPORT_TRACEPOINT_SYMBOL_GPL(fs_file_release); +#endif diff --git a/include/linux/fs.h b/include/linux/fs.h index d74314a8fa94..2702d38b57ab 100644 --- a/include/linux/fs.h +++ b/include/linux/fs.h @@ -43,7 +43,9 @@ #include <linux/cred.h> #include <linux/mnt_idmapping.h> #include <linux/slab.h> +#ifdef CONFIG_BPF_READAHEAD_OPTIMIZATION #include <linux/tracepoint-defs.h> +#endif #include <linux/kabi.h> #include <asm/byteorder.h> @@ -190,11 +192,16 @@ typedef int (dio_iodone_t)(struct kiocb *iocb, loff_t offset, /* File supports async nowait buffered writes */ #define FMODE_BUF_WASYNC ((__force fmode_t)0x80000000) +#ifdef CONFIG_BPF_READAHEAD_OPTIMIZATION /* File mode control flag, expect random access pattern */ #define FMODE_CTL_RANDOM ((__force fmode_t)0x1000) /* File mode control flag, will try to read head of the file into pagecache */ #define FMODE_CTL_WILLNEED ((__force fmode_t)0x400000) +#else +#define FMODE_CTL_RANDOM 0 +#define FMODE_CTL_WILLNEED 0 +#endif /* * Attribute flags.

[PATCH OLK-5.10] Bluetooth: Fix atomicity violation in {min,max}_key_size_set
by Liu Jian 23 Apr '24

23 Apr '24

From: Gui-Dong Han <2045gemini(a)gmail.com> stable inclusion from stable-v5.10.209 commit 394c6c0b6d9bdd7d6ebca35ca9cfbabf44c0c257 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I917MX CVE: CVE-2024-24860 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit da9065caa594d19b26e1a030fd0cc27bd365d685 upstream. In min_key_size_set(): if (val > hdev->le_max_key_size || val < SMP_MIN_ENC_KEY_SIZE) return -EINVAL; hci_dev_lock(hdev); hdev->le_min_key_size = val; hci_dev_unlock(hdev); In max_key_size_set(): if (val > SMP_MAX_ENC_KEY_SIZE || val < hdev->le_min_key_size) return -EINVAL; hci_dev_lock(hdev); hdev->le_max_key_size = val; hci_dev_unlock(hdev); The atomicity violation occurs due to concurrent execution of set_min and set_max funcs.Consider a scenario where setmin writes a new, valid 'min' value, and concurrently, setmax writes a value that is greater than the old 'min' but smaller than the new 'min'. In this case, setmax might check against the old 'min' value (before acquiring the lock) but write its value after the 'min' has been updated by setmin. This leads to a situation where the 'max' value ends up being smaller than the 'min' value, which is an inconsistency. This possible bug is found by an experimental static analysis tool developed by our team, BassCheck[1]. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported when our tool analyzes the source code of Linux 5.17. To resolve this issue, it is suggested to encompass the validity checks within the locked sections in both set_min and set_max funcs. The modification ensures that the validation of 'val' against the current min/max values is atomic, thus maintaining the integrity of the settings. With this patch applied, our tool no longer reports the bug, with the kernel configuration allyesconfig for x86_64. Due to the lack of associated hardware, we cannot test the patch in runtime testing, and just verify it according to the code logic.
