On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which wipes out any stale state. But the per CPU cached xfd value is not reset, which brings them out of sync. As a consequence a subsequent xfd_update_state() might fail to update the MSR which in turn can result in XRSTOR raising a #NM in kernel space, which crashes the kernel. To fix this, introduce xfd_set_state() to write xfd_state together with MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD.

This is incorrect usage of the API, which leads to the following warning [1]. Fix by returning if the lists are empty as there is nothing to migrate in this case.

[PATCH OLK-5.10] loop: use lo->lo_disk for kobject_uevent
by Li Nan 21 May '24

21 May '24

hulk inclusion category: bugfix bugzilla: 189922, https://gitee.com/openeuler/kernel/issues/I9PXKA CVE: NA -------------------------------- The current implimentation of partitions for loop has several issues. 'loop_device' is at the gendisk level, but it uses 'lo_device' to store block_device. A gendisk can have multiple block_devices, and 'lo_device' can be set to anyone of them through loop_configure(). This usage can lead to a null-ptr-deref issue. If 'lo_device' is set to a block_device of partition, this partition is closed and 'bd_openers' is dec to 0, the 'bd_disk' of that block_device will be set to NULL in __blkdev_put(). In this case, Accessing 'lo_device->bd_disk' will trigger the issue. The problem can be reproduced as follows: 1. create loop device loop0 and create a partition loop0p1. 2. submit the ioctl LOOP_CLR_FD by loop0. 3. submit the ioctl LOOP_SET_FD by loop0p1. 4. submit ioctl such as LOOP_SET_STATUS by loop0. Fix it by using 'lo->lo_disk' instead of 'lo->lo_device->bd_disk' for kobject_uevent().

The arithmetic implies adding together a 64-bit register with a int offset. The register was checked to be below 1<<29 when it was variable, but not when it was fixed. The offset either comes from an instruction (in which case it is 16 bit), from another register (in which case the caller checked it to be below 1<<29 [1]), or from the size of an argument to a kfunc (in which case it can be a u32 [2]).

[PATCH openEuler-22.03-LTS] bpf: Guard stack limits against 32bit overflow

From: Andrei Matei <andreimatei1(a)gmail.com> mainline inclusion from mainline-v6.8-rc1 commit 1d38a9ee81570c4bd61f557832dead4d6f816760 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q9EW CVE: CVE-2023-52676 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- This patch promotes the arithmetic around checking stack bounds to be done in the 64-bit domain, instead of the current 32bit. The arithmetic implies adding together a 64-bit register with a int offset. The register was checked to be below 1<<29 when it was variable, but not when it was fixed. The offset either comes from an instruction (in which case it is 16 bit), from another register (in which case the caller checked it to be below 1<<29 [1]), or from the size of an argument to a kfunc (in which case it can be a u32 [2]).

With having more then 2^32 blocks resize_inode is turned off by default by mke2fs. The issue can be reproduced on a smaller file system for convenience by explicitly turning off resize_inode. An on-line resize across an 8 GiB boundary (the size of a meta block group in this setup) then leads to a corruption: dev=/dev/<some_dev> # should be >= 16 GiB mkdir -p /corruption /sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15)) mount -t ext4 $dev /corruption dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15)) sha1sum /corruption/test # 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test /sbin/resize2fs $dev $((2*2**21)) # drop page cache to force reload the block from disk echo 1 > /proc/sys/vm/drop_caches sha1sum /corruption/test # 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test 2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks per block group and 2^6 are the number of block groups that make a meta block group. The last checksum might be different depending on how the file is laid out across the physical blocks. The actual corruption occurs at physical block 63*2^15 = 2064384 which would be the location of the backup of the meta block group's block descriptor. During the on-line resize the file system will be converted to meta_bg starting at s_first_meta_bg which is 2 in the example - meaning all block groups after 16 GiB. However, in ext4_flex_group_add we might add block groups that are not part of the first meta block group yet. In the reproducer we achieved this by substracting the size of a whole block group from the point where the meta block group would start. This must be considered when updating the backup block group descriptors to follow the non-meta_bg layout. The fix is to add a test whether the group to add is already part of the meta block group or not.

[PATCH openEuler-1.0-LTS] arm64: asm-bug: Add .align 2 to the end of __BUG_ENTRY
by Li Zetao 21 May '24

21 May '24

From: Jiangfeng Xiao <xiaojiangfeng(a)huawei.com> Offering: HULK hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9R0VC Reference: https://lore.kernel.org/all/1716212077-43826-1-git-send-email-xiaojiangfeng… ---------------------------------------- When CONFIG_DEBUG_BUGVERBOSE=n, we fail to add necessary padding bytes to bug_table entries, and as a result the last entry in a bug table will be ignored, potentially leading to an unexpected panic(). All prior entries in the table will be handled correctly. The arm64 ABI requires that struct fields of up to 8 bytes are naturally-aligned, with padding added within a struct such that struct are suitably aligned within arrays. When CONFIG_DEBUG_BUGVERPOSE=y, the layout of a bug_entry is: struct bug_entry { signed int bug_addr_disp; // 4 bytes signed int file_disp; // 4 bytes unsigned short line; // 2 bytes unsigned short flags; // 2 bytes } ... with 12 bytes total, requiring 4-byte alignment. When CONFIG_DEBUG_BUGVERBOSE=n, the layout of a bug_entry is: struct bug_entry { signed int bug_addr_disp; // 4 bytes unsigned short flags; // 2 bytes < implicit padding > // 2 bytes } ... with 8 bytes total, with 6 bytes of data and 2 bytes of trailing padding, requiring 4-byte alginment. When we create a bug_entry in assembly, we align the start of the entry to 4 bytes, which implicitly handles padding for any prior entries. However, we do not align the end of the entry, and so when CONFIG_DEBUG_BUGVERBOSE=n, the final entry lacks the trailing padding bytes. For the main kernel image this is not a problem as find_bug() doesn't depend on the trailing padding bytes when searching for entries: for (bug = __start___bug_table; bug < __stop___bug_table; ++bug) if (bugaddr == bug_addr(bug)) return bug; However for modules, module_bug_finalize() depends on the trailing bytes when calculating the number of entries: mod->num_bugs = sechdrs[i].sh_size / sizeof(struct bug_entry); ... and as the last bug_entry lacks the necessary padding bytes, this entry will not be counted, e.g. in the case of a single entry: sechdrs[i].sh_size == 6 sizeof(struct bug_entry) == 8; sechdrs[i].sh_size / sizeof(struct bug_entry) == 0; Consequently module_find_bug() will miss the last bug_entry when it does: for (i = 0; i < mod->num_bugs; ++i, ++bug) if (bugaddr == bug_addr(bug)) goto out; ... which can lead to a kenrel panic due to an unhandled bug. This can be demonstrated with the following module: static int __init buginit(void) { WARN(1, "hello\n"); return 0; } static void __exit bugexit(void) { } module_init(buginit); module_exit(bugexit); MODULE_LICENSE("GPL"); ... which will trigger a kernel panic when loaded: ------------[ cut here ]------------ hello Unexpected kernel BRK exception at EL1 Internal error: BRK handler: 00000000f2000800 [#1] PREEMPT SMP Modules linked in: hello(O+) CPU: 0 PID: 50 Comm: insmod Tainted: G O 6.9.1 #8 Hardware name: linux,dummy-virt (DT) pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : buginit+0x18/0x1000 [hello] lr : buginit+0x18/0x1000 [hello] sp : ffff800080533ae0 x29: ffff800080533ae0 x28: 0000000000000000 x27: 0000000000000000 x26: ffffaba8c4e70510 x25: ffff800080533c30 x24: ffffaba8c4a28a58 x23: 0000000000000000 x22: 0000000000000000 x21: ffff3947c0eab3c0 x20: ffffaba8c4e3f000 x19: ffffaba846464000 x18: 0000000000000006 x17: 0000000000000000 x16: ffffaba8c2492834 x15: 0720072007200720 x14: 0720072007200720 x13: ffffaba8c49b27c8 x12: 0000000000000312 x11: 0000000000000106 x10: ffffaba8c4a0a7c8 x9 : ffffaba8c49b27c8 x8 : 00000000ffffefff x7 : ffffaba8c4a0a7c8 x6 : 80000000fffff000 x5 : 0000000000000107 x4 : 0000000000000000 x3 : 0000000000000000 x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff3947c0eab3c0 Call trace: buginit+0x18/0x1000 [hello] do_one_initcall+0x80/0x1c8 do_init_module+0x60/0x218 load_module+0x1ba4/0x1d70 __do_sys_init_module+0x198/0x1d0 __arm64_sys_init_module+0x1c/0x28 invoke_syscall+0x48/0x114 el0_svc_common.constprop.0+0x40/0xe0 do_el0_svc+0x1c/0x28 el0_svc+0x34/0xd8 el0t_64_sync_handler+0x120/0x12c el0t_64_sync+0x190/0x194 Code: d0ffffe0 910003fd 91000000 9400000b (d4210000) ---[ end trace 0000000000000000 ]--- Kernel panic - not syncing: BRK handler: Fatal exception Fix this by always aligning the end of a bug_entry to 4 bytes, which is correct regardless of CONFIG_DEBUG_BUGVERBOSE.

With having more then 2^32 blocks resize_inode is turned off by default by mke2fs. The issue can be reproduced on a smaller file system for convenience by explicitly turning off resize_inode.

During the on-line resize the file system will be converted to meta_bg starting at s_first_meta_bg which is 2 in the example - meaning all block groups after 16 GiB. However, in ext4_flex_group_add we might add block groups that are not part of the first meta block group yet.

[PATCH openEuler-1.0-LTS] ext4: fix corruption during on-line resize

From: Maximilian Heyne <mheyne(a)amazon.de> stable inclusion from stable-v5.10.215 commit e8e8b197317228b5089ed9e7802dadf3ccaa027a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q9CF CVE: CVE-2024-35807 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit a6b3bfe176e8a5b05ec4447404e412c2a3fc92cc ] We observed a corruption during on-line resize of a file system that is larger than 16 TiB with 4k block size. With having more then 2^32 blocks resize_inode is turned off by default by mke2fs. The issue can be reproduced on a smaller file system for convenience by explicitly turning off resize_inode. An on-line resize across an 8 GiB boundary (the size of a meta block group in this setup) then leads to a corruption: dev=/dev/<some_dev> # should be >= 16 GiB mkdir -p /corruption /sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15)) mount -t ext4 $dev /corruption dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15)) sha1sum /corruption/test # 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test /sbin/resize2fs $dev $((2*2**21)) # drop page cache to force reload the block from disk echo 1 > /proc/sys/vm/drop_caches sha1sum /corruption/test # 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test 2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks per block group and 2^6 are the number of block groups that make a meta block group. The last checksum might be different depending on how the file is laid out across the physical blocks. The actual corruption occurs at physical block 63*2^15 = 2064384 which would be the location of the backup of the meta block group's block descriptor. During the on-line resize the file system will be converted to meta_bg starting at s_first_meta_bg which is 2 in the example - meaning all block groups after 16 GiB. However, in ext4_flex_group_add we might add block groups that are not part of the first meta block group yet. In the reproducer we achieved this by substracting the size of a whole block group from the point where the meta block group would start. This must be considered when updating the backup block group descriptors to follow the non-meta_bg layout. The fix is to add a test whether the group to add is already part of the meta block group or not.

[PATCH OLK-5.10] ext4: fix corruption during on-line resize
by Zhihao Cheng 21 May '24

21 May '24

From: Maximilian Heyne <mheyne(a)amazon.de> stable inclusion from stable-v5.10.215 commit e8e8b197317228b5089ed9e7802dadf3ccaa027a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q9CF CVE: CVE-2024-35807 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit a6b3bfe176e8a5b05ec4447404e412c2a3fc92cc ] We observed a corruption during on-line resize of a file system that is larger than 16 TiB with 4k block size. With having more then 2^32 blocks resize_inode is turned off by default by mke2fs. The issue can be reproduced on a smaller file system for convenience by explicitly turning off resize_inode. An on-line resize across an 8 GiB boundary (the size of a meta block group in this setup) then leads to a corruption: dev=/dev/<some_dev> # should be >= 16 GiB mkdir -p /corruption /sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15)) mount -t ext4 $dev /corruption dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15)) sha1sum /corruption/test # 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test /sbin/resize2fs $dev $((2*2**21)) # drop page cache to force reload the block from disk echo 1 > /proc/sys/vm/drop_caches sha1sum /corruption/test # 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test 2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks per block group and 2^6 are the number of block groups that make a meta block group. The last checksum might be different depending on how the file is laid out across the physical blocks. The actual corruption occurs at physical block 63*2^15 = 2064384 which would be the location of the backup of the meta block group's block descriptor. During the on-line resize the file system will be converted to meta_bg starting at s_first_meta_bg which is 2 in the example - meaning all block groups after 16 GiB. However, in ext4_flex_group_add we might add block groups that are not part of the first meta block group yet. In the reproducer we achieved this by substracting the size of a whole block group from the point where the meta block group would start. This must be considered when updating the backup block group descriptors to follow the non-meta_bg layout. The fix is to add a test whether the group to add is already part of the meta block group or not.

[PATCH openEuler-1.0-LTS] arm64: asm-bug: Add .align 2 to the end of __BUG_ENTRY
by Li Zetao 21 May '24

21 May '24

From: Jiangfeng Xiao <xiaojiangfeng(a)huawei.com> Offering: HULK hulk inclusion category: bugfix bugzilla: NA Reference: https://lore.kernel.org/all/1716212077-43826-1-git-send-email-xiaojiangfeng… ---------------------------------------- When CONFIG_DEBUG_BUGVERBOSE=n, we fail to add necessary padding bytes to bug_table entries, and as a result the last entry in a bug table will be ignored, potentially leading to an unexpected panic(). All prior entries in the table will be handled correctly. The arm64 ABI requires that struct fields of up to 8 bytes are naturally-aligned, with padding added within a struct such that struct are suitably aligned within arrays. When CONFIG_DEBUG_BUGVERPOSE=y, the layout of a bug_entry is: struct bug_entry { signed int bug_addr_disp; // 4 bytes signed int file_disp; // 4 bytes unsigned short line; // 2 bytes unsigned short flags; // 2 bytes } ... with 12 bytes total, requiring 4-byte alignment. When CONFIG_DEBUG_BUGVERBOSE=n, the layout of a bug_entry is: struct bug_entry { signed int bug_addr_disp; // 4 bytes unsigned short flags; // 2 bytes < implicit padding > // 2 bytes } ... with 8 bytes total, with 6 bytes of data and 2 bytes of trailing padding, requiring 4-byte alginment. When we create a bug_entry in assembly, we align the start of the entry to 4 bytes, which implicitly handles padding for any prior entries. However, we do not align the end of the entry, and so when CONFIG_DEBUG_BUGVERBOSE=n, the final entry lacks the trailing padding bytes. For the main kernel image this is not a problem as find_bug() doesn't depend on the trailing padding bytes when searching for entries: for (bug = __start___bug_table; bug < __stop___bug_table; ++bug) if (bugaddr == bug_addr(bug)) return bug; However for modules, module_bug_finalize() depends on the trailing bytes when calculating the number of entries: mod->num_bugs = sechdrs[i].sh_size / sizeof(struct bug_entry); ... and as the last bug_entry lacks the necessary padding bytes, this entry will not be counted, e.g. in the case of a single entry: sechdrs[i].sh_size == 6 sizeof(struct bug_entry) == 8; sechdrs[i].sh_size / sizeof(struct bug_entry) == 0; Consequently module_find_bug() will miss the last bug_entry when it does: for (i = 0; i < mod->num_bugs; ++i, ++bug) if (bugaddr == bug_addr(bug)) goto out; ... which can lead to a kenrel panic due to an unhandled bug. This can be demonstrated with the following module: static int __init buginit(void) { WARN(1, "hello\n"); return 0; } static void __exit bugexit(void) { } module_init(buginit); module_exit(bugexit); MODULE_LICENSE("GPL"); ... which will trigger a kernel panic when loaded: ------------[ cut here ]------------ hello Unexpected kernel BRK exception at EL1 Internal error: BRK handler: 00000000f2000800 [#1] PREEMPT SMP Modules linked in: hello(O+) CPU: 0 PID: 50 Comm: insmod Tainted: G O 6.9.1 #8 Hardware name: linux,dummy-virt (DT) pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : buginit+0x18/0x1000 [hello] lr : buginit+0x18/0x1000 [hello] sp : ffff800080533ae0 x29: ffff800080533ae0 x28: 0000000000000000 x27: 0000000000000000 x26: ffffaba8c4e70510 x25: ffff800080533c30 x24: ffffaba8c4a28a58 x23: 0000000000000000 x22: 0000000000000000 x21: ffff3947c0eab3c0 x20: ffffaba8c4e3f000 x19: ffffaba846464000 x18: 0000000000000006 x17: 0000000000000000 x16: ffffaba8c2492834 x15: 0720072007200720 x14: 0720072007200720 x13: ffffaba8c49b27c8 x12: 0000000000000312 x11: 0000000000000106 x10: ffffaba8c4a0a7c8 x9 : ffffaba8c49b27c8 x8 : 00000000ffffefff x7 : ffffaba8c4a0a7c8 x6 : 80000000fffff000 x5 : 0000000000000107 x4 : 0000000000000000 x3 : 0000000000000000 x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff3947c0eab3c0 Call trace: buginit+0x18/0x1000 [hello] do_one_initcall+0x80/0x1c8 do_init_module+0x60/0x218 load_module+0x1ba4/0x1d70 __do_sys_init_module+0x198/0x1d0 __arm64_sys_init_module+0x1c/0x28 invoke_syscall+0x48/0x114 el0_svc_common.constprop.0+0x40/0xe0 do_el0_svc+0x1c/0x28 el0_svc+0x34/0xd8 el0t_64_sync_handler+0x120/0x12c el0t_64_sync+0x190/0x194 Code: d0ffffe0 910003fd 91000000 9400000b (d4210000) ---[ end trace 0000000000000000 ]--- Kernel panic - not syncing: BRK handler: Fatal exception Fix this by always aligning the end of a bug_entry to 4 bytes, which is correct regardless of CONFIG_DEBUG_BUGVERBOSE.

By using a WARN_ON_ONCE() we at least give the user a chance to report any bugs triggered here - instead of getting silent hangs. None of these WARN_ON_ONCE()s are supposed to trigger, ever - so we ignore cases where a NULL check is done via a BUG_ON() and we let a NULL pointer through after a WARN_ON_ONCE(). There's one exception: WARN_ON_ONCE() arguments with side-effects, such as locking - in this case we use the return value of the WARN_ON_ONCE(), such as in: - BUG_ON(!lock_task_sighand(p, &flags)); + if (WARN_ON_ONCE(!lock_task_sighand(p, &flags))) + return; Suggested-by: Linus Torvalds <torvalds(a)linux-foundation.org> Signed-off-by: Ingo Molnar <mingo(a)kernel.org> Link: https://lore.kernel.org/r/YvSsKcAXISmshtHo@gmail.com Conflicts: kernel/sched/deadline.c kernel/sched/fair.c kernel/sched/core.c kernel/sched/sched.h [Some contexts around BUG_ON are different.

[PATCH OLK-5.10] bpf: Guard stack limits against 32bit overflow
by Pu Lehui 21 May '24

21 May '24

From: Andrei Matei <andreimatei1(a)gmail.com> mainline inclusion from mainline-v6.8-rc1 commit 1d38a9ee81570c4bd61f557832dead4d6f816760 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q9EW CVE: CVE-2023-52676 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- This patch promotes the arithmetic around checking stack bounds to be done in the 64-bit domain, instead of the current 32bit. The arithmetic implies adding together a 64-bit register with a int offset. The register was checked to be below 1<<29 when it was variable, but not when it was fixed. The offset either comes from an instruction (in which case it is 16 bit), from another register (in which case the caller checked it to be below 1<<29 [1]), or from the size of an argument to a kfunc (in which case it can be a u32 [2]). Between the register being inconsistently checked to be below 1<<29, and the offset being up to an u32, it appears that we were open to overflowing the `int`s which were currently used for arithmetic.

[PATCH openEuler-1.0-LTS] sched/all: Change all BUG_ON() instances in the scheduler to WARN_ON_ONCE()
by Zhao Wenhui 21 May '24

21 May '24

From: Ingo Molnar <mingo(a)kernel.org> mainline inclusion from mainline-v6.1-rc1 commit 09348d75a6ce60eec85c86dd0ab7babc4db3caf6 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9QW75 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- There's no good reason to crash a user's system with a BUG_ON(), chances are high that they'll never even see the crash message on Xorg, and it won't make it into the syslog either. By using a WARN_ON_ONCE() we at least give the user a chance to report any bugs triggered here - instead of getting silent hangs. None of these WARN_ON_ONCE()s are supposed to trigger, ever - so we ignore cases where a NULL check is done via a BUG_ON() and we let a NULL pointer through after a WARN_ON_ONCE(). There's one exception: WARN_ON_ONCE() arguments with side-effects, such as locking - in this case we use the return value of the WARN_ON_ONCE(), such as in: - BUG_ON(!lock_task_sighand(p, &flags)); + if (WARN_ON_ONCE(!lock_task_sighand(p, &flags))) + return; Suggested-by: Linus Torvalds <torvalds(a)linux-foundation.org> Signed-off-by: Ingo Molnar <mingo(a)kernel.org> Link: https://lore.kernel.org/r/YvSsKcAXISmshtHo@gmail.com Conflicts: kernel/sched/deadline.c kernel/sched/fair.c kernel/sched/core.c kernel/sched/sched.h [Some contexts around BUG_ON are different.

[PATCH OLK-5.10 v3] KVM: SVM: Flush pages under kvm->lock to fix UAF in svm_register_enc_region()
by Ye Bin 21 May '24

21 May '24

From: Sean Christopherson <seanjc(a)google.com> mainline inclusion from mainline-v6.8 commit 5ef1d8c1ddbf696e47b226e11888eaf8d9e8e807 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q8ZA CVE: CVE-2024-35791 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Do the cache flush of converted pages in svm_register_enc_region() before dropping kvm->lock to fix use-after-free issues where region and/or its array of pages could be freed by a different task, e.g. if userspace has __unregister_enc_region_locked() already queued up for the region. Note, the "obvious" alternative of using local variables doesn't fully resolve the bug, as region->pages is also dynamically allocated.

From: Ziqi Zhao <astrajoan(a)yahoo.com> mainline inclusion from mainline-v6.8-rc5 commit 6cdedc18ba7b9dacc36466e27e3267d201948c8d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2GX CVE: CVE-2023-52638 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The following 3 locks would race against each other, causing the deadlock situation in the Syzbot bug report: - j1939_socks_lock - active_session_list_lock - sk_session_queue_lock A reasonable fix is to change j1939_socks_lock to an rwlock, since in the rare situations where a write lock is required for the linked list that j1939_socks_lock is protecting, the code does not attempt to acquire any more locks. This would break the circular lock dependency, where, for example, the current thread already locks j1939_socks_lock and attempts to acquire sk_session_queue_lock, and at the same time, another thread attempts to acquire j1939_socks_lock while holding sk_session_queue_lock. NOTE: This patch along does not fix the unregister_netdevice bug reported by Syzbot; instead, it solves a deadlock situation to prepare for one or more further patches to actually fix the Syzbot bug, which appears to be a reference counting problem within the j1939 codebase.

The splat occurs because skb->data points past skb->head allocated area. This is because neigh layer does: __skb_pull(skb, skb_network_offset(skb)); ... but skb_network_offset() returns a negative offset and __skb_pull() arg is unsigned. IOW, we skb->data gets "adjusted" by a huge value. The negative value is returned because skb->head and skb->data distance is more than 64k and skb->network_header (u16) has wrapped around. The bug is in the ip_tunnel infrastructure, which can cause dev->needed_headroom to increment ad infinitum. The syzkaller reproducer consists of packets getting routed via a gre tunnel, and route of gre encapsulated packets pointing at another (ipip) tunnel. The ipip encapsulation finds gre0 as next output device. This results in the following pattern: 1). First packet is to be sent out via gre0. Route lookup found an output device, ipip0. 2). ip_tunnel_xmit for gre0 bumps gre0->needed_headroom based on the future output device, rt.dev->needed_headroom (ipip0). 3). ip output / start_xmit moves skb on to ipip0. which runs the same code path again (xmit recursion). 4). Routing step for the post-gre0-encap packet finds gre0 as output device to use for ipip0 encapsulated packet. tunl0->needed_headroom is then incremented based on the (already bumped) gre0 device headroom. This repeats for every future packet: gre0->needed_headroom gets inflated because previous packets' ipip0 step incremented rt->dev (gre0) headroom, and ipip0 incremented because gre0 needed_headroom was increased. For each subsequent packet, gre/ipip0->needed_headroom grows until post-expand-head reallocations result in a skb->head/data distance of more than 64k. Once that happens, skb->network_header (u16) wraps around when pskb_expand_head tries to make sure that skb_network_offset() is unchanged after the headroom expansion/reallocation. After this skb_network_offset(skb) returns a different (and negative) result post headroom expansion. The next trip to neigh layer (or anything else that would __skb_pull the network header) makes skb->data point to a memory location outside skb->head area. v2: Cap the needed_headroom update to an arbitarily chosen upperlimit to prevent perpetual increase instead of dropping the headroom increment completely.

[PATCH OLK-5.10] irqchip/gic-v3-its: Prevent double free on error
by Liu Mingrui 21 May '24

21 May '24

From: Guanrui Huang <guanrui.huang(a)linux.alibaba.com> stable inclusion from stable-v5.10.216 commit aa44d21574751a7d6bca892eb8e0e9ac68372e52 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q9HX CVE: CVE-2024-35847 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit c26591afd33adce296c022e3480dea4282b7ef91 upstream. The error handling path in its_vpe_irq_domain_alloc() causes a double free when its_vpe_init() fails after successfully allocating at least one interrupt.

[PATCH OLK-6.6] jbd2: speed up jbd2_transaction_committed()
by Zhang Yi 20 May '24

20 May '24

hulk inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/I9QSJ5 CVE: NA -------------------------------- jbd2_transaction_committed() is used to check whether a transaction with the given tid has already committed, it holds j_state_lock in read mode and check the tid of current running transaction and committing transaction, but holding the j_state_lock is expensive. We have already stored the sequence number of the most recently committed transaction in journal t->j_commit_sequence, we could do this check by comparing it with the given tid instead. If the given tid isn't smaller than j_commit_sequence, we can ensure that the given transaction has been committed. That way we could drop the expensive lock and achieve about 10% ~ 20% performance gains in concurrent DIOs on may virtual machine with 100G ramdisk. fio -filename=/mnt/foo -direct=1 -iodepth=10 -rw=$rw -ioengine=libaio \ -bs=4k -size=10G -numjobs=10 -runtime=60 -overwrite=1 -name=test \ -group_reporting Before: overwrite IOPS=88.2k, BW=344MiB/s read IOPS=95.7k, BW=374MiB/s rand overwrite IOPS=98.7k, BW=386MiB/s randread IOPS=102k, BW=397MiB/s After: overwrite IOPS=105k, BW=410MiB/s read IOPS=112k, BW=436MiB/s rand overwrite IOPS=104k, BW=404MiB/s randread IOPS=111k, BW=432MiB/s CC: Dave Chinner <david(a)fromorbit.com> Suggested-by: Dave Chinner <david(a)fromorbit.com> Link: https://lore.kernel.org/linux-ext4/ZjILCPNZRHeazSqV@dread.disaster.area/ Signed-off-by: Zhang Yi <yi.zhang(a)huawei.com> Reviewed-by: Jan Kara <jack(a)suse.cz> --- fs/jbd2/commit.c | 2 +- fs/jbd2/journal.c | 12 +----------- 2 files changed, 2 insertions(+), 12 deletions(-) diff --git a/fs/jbd2/commit.c b/fs/jbd2/commit.c index 5e122586e06e..8244cab17688 100644 --- a/fs/jbd2/commit.c +++ b/fs/jbd2/commit.c @@ -1108,7 +1108,7 @@ void jbd2_journal_commit_transaction(journal_t *journal) commit_transaction->t_state = T_COMMIT_CALLBACK; J_ASSERT(commit_transaction == journal->j_committing_transaction); - journal->j_commit_sequence = commit_transaction->t_tid; + WRITE_ONCE(journal->j_commit_sequence, commit_transaction->t_tid); journal->j_committing_transaction = NULL; commit_time = ktime_to_ns(ktime_sub(ktime_get(), start_time)); diff --git a/fs/jbd2/journal.c b/fs/jbd2/journal.c index 19c69229ac6e..fc4c7a2bf6d5 100644 --- a/fs/jbd2/journal.c +++ b/fs/jbd2/journal.c @@ -789,17 +789,7 @@ EXPORT_SYMBOL(jbd2_fc_end_commit_fallback); /* Return 1 when transaction with given tid has already committed. */ int jbd2_transaction_committed(journal_t *journal, tid_t tid) { - int ret = 1; - - read_lock(&journal->j_state_lock); - if (journal->j_running_transaction && - journal->j_running_transaction->t_tid == tid) - ret = 0; - if (journal->j_committing_transaction && - journal->j_committing_transaction->t_tid == tid) - ret = 0; - read_unlock(&journal->j_state_lock); - return ret; + return tid_geq(READ_ONCE(journal->j_commit_sequence), tid); } EXPORT_SYMBOL(jbd2_transaction_committed); -- 2.39.2

The error handling path in its_vpe_irq_domain_alloc() causes a double free when its_vpe_init() fails after successfully allocating at least one interrupt. This happens because its_vpe_irq_domain_free() frees the interrupts along with the area bitmap and the vprop_page and its_vpe_irq_domain_alloc() subsequently frees the area bitmap and the vprop_page again. Fix this by unconditionally invoking its_vpe_irq_domain_free() which handles all cases correctly and by removing the bitmap/vprop_page freeing from its_vpe_irq_domain_alloc().

[PATCH OLK-5.10] mm/swapfile: fix infinite loop in get_swap_pages after set memory.swapfile

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9QRNR CVE: NA -------------------------------- In get_swap_pages(), we select the swap device based on the priority by default. If two or more devices have the same priority, their positions in the avail_lists will move in a circle in plist_requeue(). After set memory.swapfile in a memory cgroup and the priority of the matched swap is less than the priority of these swap, the loop will be confined to these swaps with same priority and can't select the specified swap forever.

[PATCH OLK-5.10] netfilter: ipset: fix performance regression in swap operation
by Guo Mengqi 20 May '24

20 May '24

From: Jozsef Kadlecsik <kadlec(a)netfilter.org> stable inclusion from stable-v5.10.210 commit a24d5f2ac8ef702a58e55ec276aad29b4bd97e05 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9HL6P Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- commit 97f7cf1cd80eeed3b7c808b7c12463295c751001 upstream. The patch "netfilter: ipset: fix race condition between swap/destroy and kernel side add/del/test", commit 28628fa9 fixes a race condition. But the synchronize_rcu() added to the swap function unnecessarily slows it down: it can safely be moved to destroy and use call_rcu() instead. Eric Dumazet pointed out that simply calling the destroy functions as rcu callback does not work: sets with timeout use garbage collectors which need cancelling at destroy which can wait. Therefore the destroy functions are split into two: cancelling garbage collectors safely at executing the command received by netlink and moving the remaining part only into the rcu callback.

From: Meng Li <Meng.Li(a)windriver.com> stable inclusion from stable-v5.10.146 commit 657803b918e097e47d99d1489da83a603c36bcdd category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9KHLI Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 69bef19d6b9700e96285f4b4e28691cda3dcd0d1 upstream. When running gpio test on nxp-ls1028 platform with below command gpiomon --num-events=3 --rising-edge gpiochip1 25 There will be a warning trace as below: Call trace: free_irq+0x204/0x360 lineevent_free+0x64/0x70 gpio_ioctl+0x598/0x6a0 __arm64_sys_ioctl+0xb4/0x100 invoke_syscall+0x5c/0x130 ...... el0t_64_sync+0x1a0/0x1a4 The reason of this issue is that calling request_threaded_irq() function failed, and then lineevent_free() is invoked to release the resource. Since the lineevent_state::irq was already set, so the subsequent invocation of free_irq() would trigger the above warning call trace. To fix this issue, set the lineevent_state::irq after the IRQ register successfully.

Like the call trace shown above, rcu_node->lock will not be released until all the stalled cpus' backtrace finished in nmi_cpu_backtrace() or 10s timeout in nmi_trigger_cpumask_backtrace(), if there are pending IPI callbacks in the smp call_single_queue ahead of the ipi_cpu_backtrace callback contending for the same rcu_node->lock, deadlock will be inevitable. To avoid such problems, shorten the critical section that rcu_node->lock protects to avoid waiting for the backtrace process finish.

Like the call trace shown above, rcu_node->lock will not be released until all the stalled cpus' backtrace finished in nmi_cpu_backtrace() or 10s timeout in nmi_trigger_cpumask_backtrace(), if there are pending IPI callbacks in the smp call_single_queue ahead of the ipi_cpu_backtrace callback contending for the same rcu_node->lock, deadlock will be inevitable. To avoid such problems, shorten the critical section that rcu_node->lock protects to avoid waiting for the backtrace process finish.

[PATCH OLK-6.6 00/18] arm64: perf: Add support for event counting threshold
by Junhao He 17 May '24

17 May '24

counting of PMU events depending on how much the event increments on a single cycle. Two new config fields for perf_event_open have been added, and a PMU cap file for reading the max_threshold. See the second commit message and the docs in the last commit for more details. The feature is not currently supported on KVM guests, and PMMIR is set to read as zero, so it's not advertised as available. But it can be added at a later time. Writes to PMEVTYPER.TC and TH from guests are already RES0. The change has been validated on the Arm FVP model: # Zero values, works as expected (as before). $ perf stat -e dtlb_walk/threshold=0,threshold_compare=0/ -- true 5962 dtlb_walk/threshold=0,threshold_compare=0/ # Threshold >= 255 causes count to be 0 because dtlb_walk doesn't # increase by more than 1 per cycle. $ perf stat -e dtlb_walk/threshold=255,threshold_compare=2/ -- true 0 dtlb_walk/threshold=255,threshold_compare=2/ # Keeping comparison as >= but lowering the threshold to 1 makes the # count return. $ perf stat -e dtlb_walk/threshold=1,threshold_compare=2/ -- true 6329 dtlb_walk/threshold=1,threshold_compare=2/ Anshuman Khandual (3): drivers: perf: arm_pmuv3: Read PMMIR_EL1 unconditionally drivers: perf: arm_pmuv3: Drop some unused arguments from armv8_pmu_init() drivers: perf: arm_pmuv3: Add new macro PMUV3_INIT_MAP_EVENT() James Clark (11): arm: perf: Remove inlines from arm_pmuv3.c arm: perf/kvm: Use GENMASK for ARMV8_PMU_PMCR_N arm: perf: Use GENMASK for PMMIR fields arm: perf: Convert remaining fields to use GENMASK arm64: perf: Include threshold control fields in PMEVTYPER mask arm: pmu: Share user ABI format mechanism with SPE perf/arm_dmc620: Remove duplicate format attribute #defines arm: pmu: Move error message and -EOPNOTSUPP to individual PMUs arm64: perf: Add support for event counting threshold Documentation: arm64: Document the PMU event counting threshold feature arm: perf: Fix ARCH=arm build with GCC Oliver Upton (2): KVM: arm64: Make PMEVTYPER<n>_EL0.NSH RES0 if EL2 isn't advertised KVM: arm64: Add PMU event filter bits required if EL3 is implemented Reiji Watanabe (1): KVM: arm64: PMU: Add a helper to read a vCPU's PMCR_EL0 Will Deacon (1): Revert "perf/arm_dmc620: Remove duplicate format attribute #defines" Documentation/arch/arm64/perf.rst | 72 ++++++++ arch/arm/kernel/perf_event_v7.c | 6 +- arch/arm64/kvm/arm.c | 3 +- arch/arm64/kvm/pmu-emul.c | 58 +++++-- arch/arm64/kvm/sys_regs.c | 21 ++- drivers/perf/apple_m1_cpu_pmu.c | 6 +- drivers/perf/arm_pmu.c | 11 +- drivers/perf/arm_pmuv3.c | 266 ++++++++++++++++++------------ drivers/perf/arm_spe_pmu.c | 22 --- include/kvm/arm_pmu.h | 11 ++ include/linux/perf/arm_pmu.h | 22 +++ include/linux/perf/arm_pmuv3.h | 43 +++-- 12 files changed, 359 insertions(+), 182 deletions(-) -- 2.33.0

[PATCH OLK-5.10] drm/i915/gt: Reset queue_priority_hint on parking
by Wenyu Huang 17 May '24

17 May '24

From: Chris Wilson <chris(a)chris-wilson.co.uk> stable inclusion from stable-v5.10.216 commit fe34587acc995e7b1d7a5d3444a0736721ec32b3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L5FX CVE: CVE-2024-26937 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 4a3859ea5240365d21f6053ee219bb240d520895 upstream. Originally, with strict in order execution, we could complete execution only when the queue was empty. Preempt-to-busy allows replacement of an active request that may complete before the preemption is processed by HW. If that happens, the request is retired from the queue, but the queue_priority_hint remains set, preventing direct submission until after the next CS interrupt is processed. This preempt-to-busy race can be triggered by the heartbeat, which will also act as the power-management barrier and upon completion allow us to idle the HW. We may process the completion of the heartbeat, and begin parking the engine before the CS event that restores the queue_priority_hint, causing us to fail the assertion that it is MIN. <3>[ 166.210729] __engine_park:283 GEM_BUG_ON(engine->sched_engine->queue_priority_hint != (-((int)(~0U >> 1)) - 1)) <0>[ 166.210781] Dumping ftrace buffer: <0>[ 166.210795] --------------------------------- ... <0>[ 167.302811] drm_fdin-1097 2..s1. 165741070us : trace_ports: 0000:00:02.0 rcs0: promote { ccid:20 1217:2 prio 0 } <0>[ 167.302861] drm_fdin-1097 2d.s2. 165741072us : execlists_submission_tasklet: 0000:00:02.0 rcs0: preempting last=1217:2, prio=0, hint=2147483646 <0>[ 167.302928] drm_fdin-1097 2d.s2. 165741072us : __i915_request_unsubmit: 0000:00:02.0 rcs0: fence 1217:2, current 0 <0>[ 167.302992] drm_fdin-1097 2d.s2. 165741073us : __i915_request_submit: 0000:00:02.0 rcs0: fence 3:4660, current 4659 <0>[ 167.303044] drm_fdin-1097 2d.s1. 165741076us : execlists_submission_tasklet: 0000:00:02.0 rcs0: context:3 schedule-in, ccid:40 <0>[ 167.303095] drm_fdin-1097 2d.s1. 165741077us : trace_ports: 0000:00:02.0 rcs0: submit { ccid:40 3:4660* prio 2147483646 } <0>[ 167.303159] kworker/-89 11..... 165741139us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence c90:2, current 2 <0>[ 167.303208] kworker/-89 11..... 165741148us : __intel_context_do_unpin: 0000:00:02.0 rcs0: context:c90 unpin <0>[ 167.303272] kworker/-89 11..... 165741159us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence 1217:2, current 2 <0>[ 167.303321] kworker/-89 11..... 165741166us : __intel_context_do_unpin: 0000:00:02.0 rcs0: context:1217 unpin <0>[ 167.303384] kworker/-89 11..... 165741170us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence 3:4660, current 4660 <0>[ 167.303434] kworker/-89 11d..1. 165741172us : __intel_context_retire: 0000:00:02.0 rcs0: context:1216 retire runtime: { total:56028ns, avg:56028ns } <0>[ 167.303484] kworker/-89 11..... 165741198us : __engine_park: 0000:00:02.0 rcs0: parked <0>[ 167.303534] <idle>-0 5d.H3. 165741207us : execlists_irq_handler: 0000:00:02.0 rcs0: semaphore yield: 00000040 <0>[ 167.303583] kworker/-89 11..... 165741397us : __intel_context_retire: 0000:00:02.0 rcs0: context:1217 retire runtime: { total:325575ns, avg:0ns } <0>[ 167.303756] kworker/-89 11..... 165741777us : __intel_context_retire: 0000:00:02.0 rcs0: context:c90 retire runtime: { total:0ns, avg:0ns } <0>[ 167.303806] kworker/-89 11..... 165742017us : __engine_park: __engine_park:283 GEM_BUG_ON(engine->sched_engine->queue_priority_hint != (-((int)(~0U >> 1)) - 1)) <0>[ 167.303811] --------------------------------- <4>[ 167.304722] ------------[ cut here ]------------ <2>[ 167.304725] kernel BUG at drivers/gpu/drm/i915/gt/intel_engine_pm.c:283! <4>[ 167.304731] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI <4>[ 167.304734] CPU: 11 PID: 89 Comm: kworker/11:1 Tainted: G W 6.8.0-rc2-CI_DRM_14193-gc655e0fd2804+ #1 <4>[ 167.304736] Hardware name: Intel Corporation Rocket Lake Client Platform/RocketLake S UDIMM 6L RVP, BIOS RKLSFWI1.R00.3173.A03.2204210138 04/21/2022 <4>[ 167.304738] Workqueue: i915-unordered retire_work_handler [i915] <4>[ 167.304839] RIP: 0010:__engine_park+0x3fd/0x680 [i915] <4>[ 167.304937] Code: 00 48 c7 c2 b0 e5 86 a0 48 8d 3d 00 00 00 00 e8 79 48 d4 e0 bf 01 00 00 00 e8 ef 0a d4 e0 31 f6 bf 09 00 00 00 e8 03 49 c0 e0 <0f> 0b 0f 0b be 01 00 00 00 e8 f5 61 fd ff 31 c0 e9 34 fd ff ff 48 <4>[ 167.304940] RSP: 0018:ffffc9000059fce0 EFLAGS: 00010246 <4>[ 167.304942] RAX: 0000000000000200 RBX: 0000000000000000 RCX: 0000000000000006 <4>[ 167.304944] RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000009 <4>[ 167.304946] RBP: ffff8881330ca1b0 R08: 0000000000000001 R09: 0000000000000001 <4>[ 167.304947] R10: 0000000000000001 R11: 0000000000000001 R12: ffff8881330ca000 <4>[ 167.304948] R13: ffff888110f02aa0 R14: ffff88812d1d0205 R15: ffff88811277d4f0 <4>[ 167.304950] FS: 0000000000000000(0000) GS:ffff88844f780000(0000) knlGS:0000000000000000 <4>[ 167.304952] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 <4>[ 167.304953] CR2: 00007fc362200c40 CR3: 000000013306e003 CR4: 0000000000770ef0 <4>[ 167.304955] PKRU: 55555554 <4>[ 167.304957] Call Trace: <4>[ 167.304958] <TASK> <4>[ 167.305573] ____intel_wakeref_put_last+0x1d/0x80 [i915] <4>[ 167.305685] i915_request_retire.part.0+0x34f/0x600 [i915] <4>[ 167.305800] retire_requests+0x51/0x80 [i915] <4>[ 167.305892] intel_gt_retire_requests_timeout+0x27f/0x700 [i915] <4>[ 167.305985] process_scheduled_works+0x2db/0x530 <4>[ 167.305990] worker_thread+0x18c/0x350 <4>[ 167.305993] kthread+0xfe/0x130 <4>[ 167.305997] ret_from_fork+0x2c/0x50 <4>[ 167.306001] ret_from_fork_asm+0x1b/0x30 <4>[ 167.306004] </TASK> It is necessary for the queue_priority_hint to be lower than the next request submission upon waking up, as we rely on the hint to decide when to kick the tasklet to submit that first request.

[PATCH openEuler-1.0-LTS] Bluetooth: Fix use-after-free bugs caused by sco_sock_timeout

From: Duoming Zhou <duoming(a)zju.edu.cn> mainline inclusion from mainline-v6.9 commit 483bc08181827fc475643272ffb69c533007e546 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9OZA9 CVE: CVE-2024-27398 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- When the sco connection is established and then, the sco socket is releasing, timeout_work will be scheduled to judge whether the sco disconnection is timeout.

[PATCH OLK-6.6] perf parse-events: Make legacy events lower priority than sysfs/JSON
by Junhao He 17 May '24

17 May '24

mainline inclusion from mainline-v6.8-rc1 commit a24d9d9dc096fc0d0bd85302c9a4fe4fe3b1107b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9Q2KV CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- The perf tool has previously made legacy events the priority so with or without a PMU the legacy event would be opened: $ perf stat -e cpu-cycles,cpu/cpu-cycles/ true Using CPUID GenuineIntel-6-8D-1 intel_pt default config: tsc,mtc,mtc_period=3,psb_period=3,pt,branch Attempting to add event pmu 'cpu' with 'cpu-cycles,' that may result in non-fatal errors After aliases, add event pmu 'cpu' with 'cpu-cycles,' that may result in non-fatal errors Control descriptor is not initialized ------------------------------------------------------------ perf_event_attr: type 0 (PERF_TYPE_HARDWARE) size 136 config 0 (PERF_COUNT_HW_CPU_CYCLES) sample_type IDENTIFIER read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING disabled 1 inherit 1 enable_on_exec 1 exclude_guest 1 ------------------------------------------------------------ sys_perf_event_open: pid 833967 cpu -1 group_fd -1 flags 0x8 = 3 ------------------------------------------------------------ perf_event_attr: type 0 (PERF_TYPE_HARDWARE) size 136 config 0 (PERF_COUNT_HW_CPU_CYCLES) sample_type IDENTIFIER read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING disabled 1 inherit 1 enable_on_exec 1 exclude_guest 1 ------------------------------------------------------------ ... Fixes to make hybrid/BIG.little PMUs behave correctly, ie as core PMUs capable of opening legacy events on each, removing hard coded "cpu_core" and "cpu_atom" Intel PMU names, etc. caused a behavioral difference on Apple/ARM due to latent issues in the PMU driver reported in: https://lore.kernel.org/lkml/08f1f185-e259-4014-9ca4-6411d5c1bc65@marcan.st/ As part of that report Mark Rutland <mark.rutland(a)arm.com> requested that legacy events not be higher in priority when a PMU is specified reversing what has until this change been perf's default behavior. With this change the above becomes: $ perf stat -e cpu-cycles,cpu/cpu-cycles/ true Using CPUID GenuineIntel-6-8D-1 Attempt to add: cpu/cpu-cycles=0/ ..after resolving event: cpu/event=0x3c/ Control descriptor is not initialized ------------------------------------------------------------ perf_event_attr: type 0 (PERF_TYPE_HARDWARE) size 136 config 0 (PERF_COUNT_HW_CPU_CYCLES) sample_type IDENTIFIER read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING disabled 1 inherit 1 enable_on_exec 1 exclude_guest 1 ------------------------------------------------------------ sys_perf_event_open: pid 827628 cpu -1 group_fd -1 flags 0x8 = 3 ------------------------------------------------------------ perf_event_attr: type 4 (PERF_TYPE_RAW) size 136 config 0x3c sample_type IDENTIFIER read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING disabled 1 inherit 1 enable_on_exec 1 exclude_guest 1 ------------------------------------------------------------ ... So the second event has become a raw event as /sys/devices/cpu/events/cpu-cycles exists. A fix was necessary to config_term_pmu in parse-events.c as check_alias expansion needs to happen after config_term_pmu, and config_term_pmu may need calling a second time because of this. config_term_pmu is updated to not use the legacy event when the PMU has such a named event (either from JSON or sysfs). The bulk of this change is updating all of the parse-events test expectations so that if a sysfs/JSON event exists for a PMU the test doesn't fail - a further sign, if it were needed, that the legacy event priority was a known and tested behavior of the perf tool.

[PATCH openEuler-1.0-LTS] firewire: nosy: ensure user_length is taken into account when fetching packet contents
by Hongbo Li 17 May '24

17 May '24

From: Thanassis Avgerinos <thanassis.avgerinos(a)gmail.com> mainline inclusion from mainline-v6.9-rc7 commit 38762a0763c10c24a4915feee722d7aa6e73eb98 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9OZA3 CVE: CVE-2024-27401 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Ensure that packet_buffer_get respects the user_length provided. If the length of the head packet exceeds the user_length, packet_buffer_get will now return 0 to signify to the user that no data were read and a larger buffer size is required.

[PATCH OLK-5.10] firewire: nosy: ensure user_length is taken into account when fetching packet contents
by Hongbo Li 17 May '24

17 May '24

From: Thanassis Avgerinos <thanassis.avgerinos(a)gmail.com> mainline inclusion from mainline-v6.9-rc7 commit 38762a0763c10c24a4915feee722d7aa6e73eb98 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9OZA3 CVE: CVE-2024-27401 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Ensure that packet_buffer_get respects the user_length provided. If the length of the head packet exceeds the user_length, packet_buffer_get will now return 0 to signify to the user that no data were read and a larger buffer size is required. Helps prevent user space overflows.
