[PATCH OLK-5.10] iomap: Ensure sub-page dirty state is set during mmap writes
by Long Li 03 Jun '24

03 Jun '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9UNQS CVE: NA ------------------------------------------ While running xfstests, specifically test xfs/032, the following errors were reported: XFS (sdb): ino 4a data fork has delalloc extent at [0x3c:0x10] XFS: Assertion failed: 0, file: fs/xfs/xfs_icache.c, line: 1854 The issue stems from the dirty state of sub-pages not being set during mmap writes. This behavior was observed after the introduction of the commit 99e9a55ba32b ("iomap: add support to track dirty state of sub-pages"), which enabled iomap to track the dirty state of sub-pages when the block size is smaller than the page size. Currently, iomap updates the sub-page dirty state only in `__iomap_write_end()`. However, the mmap write path does not invoke this function, resulting in dirty pages created by mmap writes not being scheduled for write-back. This patch fixes the issue by ensuring that the sub-page dirty state is set during mmap writes.

[PATCH OLK-5.10 v3 00/11] Memory access profiler(SPE) driven NUMA balancing
by Ze Zuo 03 Jun '24

03 Jun '24

Hi, In Arm processors, there is a hardware PMU (Performance Monitoring Unit) facility called Statistical Profiling Extension (SPE) that can gather memory access metrics. In this patchset, SPE is exploited as an access information sampling approach to drive NUMA balancing. This sampling approach is introducedto replace the method based on address space scanning and hint faults with the access information provided by the hardware. With this, it is no longer necessary for NUMA balancing to scan over the address space periodically and rely on task-to-page association built by NUMA hint faults. Instead, the access samples obtained from hardware PMU are fed to NUMA balancing as equivalents to page fault. Except for the replaced sampling approach, the rest of the NUMA balancing policy is retained to do pages and tasks migrations according to the samples. Profiling based on SPE is an valid alternative sampling approach in NUMA balancing for the optimal page and task placement. This can be also extended to other architectures as long as there is a hardware PMU that supports memory access profiling. An abstract layer mem_sampling is introduced to reserve support for other kernel features and different types of hardware PMU. To help evaluate performance of this approach in system, syctl interfaces are added to enable/disable hardware mem sampling. NUMA balancing sampling approach can be also switched back to hint-faults- based approach dynamically.

The set/test_bit() functions take a bit number instead of a shifted value. Passing a shifted value is a double shift bug like doing BIT(BIT(1)). The double shift bug doesn't cause a problem here because we are only checking 0 and 1 but if the value was 5 or above then it can lead to a buffer overflow.

The function udf_tgetblk is defined in udf/misc.c and returns the value of sb_getblk function that could be NULL. Then, epos.bh is used without any check, causing a possible NULL pointer dereference when sb_getblk fails. This fix adds a check to validate the value of epos.bh.

[PATCH OLK-6.6] fix mlock in OLK-6.6
by Wupeng Ma 03 Jun '24

03 Jun '24

From: Ma Wupeng <mawupeng1(a)huawei.com> While testing mlock, we have a problem if the len of mlock is ULONG_MAX. The return value of mlock is zero. But nothing will be locked since the len in do_mlock overflows to zero due to the following code in mlock: len = PAGE_ALIGN(len + (offset_in_page(start))); The same problem happens in munlock. Fix it by return -EINVAL if len overflows. Ma Wupeng (1): mm/mlock: return EINVAL for illegal user memory range in mlock mm/mlock.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) -- 2.25.1

[PATCH openEuler-1.0-LTS] arm64: asm-bug: Add .align 2 to the end of __BUG_ENTRY
by Li Zetao 03 Jun '24

03 Jun '24

From: Jiangfeng Xiao <xiaojiangfeng(a)huawei.com> mainline inclusion from mainline-v6.10-rc1 commit ffbf4fb9b5c12ff878a10ea17997147ea4ebea6f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9R0VC CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- 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.

[PATCH OLK-5.10 1/2] iommu/iova: free iovas on each cpu in flush queue
by Zhang Zekun 03 Jun '24

03 Jun '24

During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference. For ex: on platforms where PCI speed change is supported through ACPI ATCS method, the link speed of current state needs to be queried before deciding on changing to final power state's link speed. The logic to query ATCS-support was broken on certain platforms. The issue became visible when broken ATCS-support logic got fixed with commit f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

[PATCH OLK-5.10 v2 00/11] Memory access profiler(SPE) driven NUMA balancing
by Ze Zuo 02 Jun '24

02 Jun '24

Hi, In Arm processors, there is a hardware PMU (Performance Monitoring Unit) facility called Statistical Profiling Extension (SPE) that can gather memory access metrics. In this patchset, SPE is exploited as an access information sampling approach to drive NUMA balancing. This sampling approach is introducedto replace the method based on address space scanning and hint faults with the access information provided by the hardware. With this, it is no longer necessary for NUMA balancing to scan over the address space periodically and rely on task-to-page association built by NUMA hint faults. Instead, the access samples obtained from hardware PMU are fed to NUMA balancing as equivalents to page fault. Except for the replaced sampling approach, the rest of the NUMA balancing policy is retained to do pages and tasks migrations according to the samples. Profiling based on SPE is an valid alternative sampling approach in NUMA balancing for the optimal page and task placement. This can be also extended to other architectures as long as there is a hardware PMU that supports memory access profiling. An abstract layer mem_sampling is introduced to reserve support for other kernel features and different types of hardware PMU. To help evaluate performance of this approach in system, syctl interfaces are added to enable/disable hardware mem sampling. NUMA balancing sampling approach can be also switched back to hint-faults- based approach dynamically. TODOs Currently, SPE for NUMA balance does not support PMD-level page migration, but it will be supported in later version. Changes since v1: -- clean code, no functional change.

[PATCH openEuler-1.0-LTS] comedi: dt9812: fix DMA buffers on stack
by Wang Hai 01 Jun '24

01 Jun '24

From: Johan Hovold <johan(a)kernel.org> stable inclusion from stable-v4.19.217 commit 39ea61037ae78f14fa121228dd962ea3280eacf3 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RD6O CVE: CVE-2021-47477 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 536de747bc48262225889a533db6650731ab25d3 upstream. USB transfer buffers are typically mapped for DMA and must not be allocated on the stack or transfers will fail. Allocate proper transfer buffers in the various command helpers and return an error on short transfers instead of acting on random stack data. Note that this also fixes a stack info leak on systems where DMA is not used as 32 bytes are always sent to the device regardless of how short the command is.

This might cause memory corruption should wmi_char_open() be unable to find its driver, something which can happen when the associated WMI device is deleted in wmi_free_devices().

[PATCH openEuler-1.0-LTS] drm/amd/pm: Update intermediate power state for SI
by Liu Chuang 31 May '24

31 May '24

From: Lijo Lazar <lijo.lazar(a)amd.com> mainline inclusion from mainline-v5.15-rc3 commit ab39d3cef526ba09c4c6923b4cd7e6ec1c5d4faa category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9TKIT CVE: CVE-2021-47362 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Update the current state as boot state during dpm initialization. During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference. For ex: on platforms where PCI speed change is supported through ACPI ATCS method, the link speed of current state needs to be queried before deciding on changing to final power state's link speed. The logic to query ATCS-support was broken on certain platforms. The issue became visible when broken ATCS-support logic got fixed with commit f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").
