[PATCH OLK-5.10] ACPI: APEI: Handle repeated SEA error interrupts storm
by Junxian Huang 22 Jan '26

22 Jan '26

From: Junhao He <hejunhao3(a)h-partners.com> driver inclusion category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/8377 --------------------------------------------------------------------------- The do_sea() function defaults to using firmware-first mode, if supported. It invoke acpi/apei/ghes ghes_notify_sea() to report and handling the SEA error, The GHES uses a buffer to cache the most recent 4 kinds of SEA errors. If the same kind SEA error occurs again, GHES will skip to reporting this SEA error and will not add it to the "ghes_estatus_llist" list until the cache times out after 10 seconds, at which point the SEA error will be reprocessed. The GHES invoke ghes_proc_in_irq() to handle the SEA error, which ultimately executes memory_failure to process the page with hardware memory corruption. If the same SEA error appears multiple times consecutively, it indicates that the previous handling was incomplete or unable to resolve the fault. In such cases, it is more appropriate to return a failure when encountering the same error again, and then proceed to arm64_do_kernel_sea for further processing. When hardware memory corruption occurs, a memory error interrupt is triggered. If the kernel accesses this erroneous data, it will trigget the SEA error exception handler. All such handlers will call memory_failure() to handle the faulty page. If a memory error interrupt occurs first, followed by an SEA error interrupt, the faulty page is first marked as poisoned by the memory error interrupt process, and then the SEA error interrupt handling process will send a SIGBUS signel to the process accessing the poisoned page. However, if the SEA interrupt is reported first, the following exceptional scenario occurs: When a user process directly requests and accesses a page with hardware memory corruption via mmap (such as with devmem), the page containing this address may still be in a free buddy state in the kernel. At this point, the page is marked as "poisoned" during the SEA claim memory_failure(). However, since the process does not request the page through the kernel's MMU, the kernel cannot send SIGBUS signel to the processes. And the memory error interrupt handling process not support send SIGBUS signel. As a result, these processes continues to access the faulty page, causing repeated entries into the SEA exception handler. At this time, it lead to an SEA error interrupt storm. The following error logs is explained using the devmem process: NOTICE: SEA Handle NOTICE: SpsrEl3 = 0x60001000, ELR_EL3 = 0xffffc6ab42671400 NOTICE: skt[0x0]die[0x0]cluster[0x0]core[0x1] NOTICE: EsrEl3 = 0x92000410 NOTICE: PA is valid: 0x1000093c00 NOTICE: Hest Set GenericError Data [ 1419.542401][ C1] {57}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 9 [ 1419.551435][ C1] {57}[Hardware Error]: event severity: recoverable [ 1419.557865][ C1] {57}[Hardware Error]: Error 0, type: recoverable [ 1419.564295][ C1] {57}[Hardware Error]: section_type: ARM processor error [ 1419.571421][ C1] {57}[Hardware Error]: MIDR: 0x0000000000000000 [ 1419.571434][ C1] {57}[Hardware Error]: Multiprocessor Affinity Register (MPIDR): 0x0000000081000100 [ 1419.586813][ C1] {57}[Hardware Error]: error affinity level: 0 [ 1419.586821][ C1] {57}[Hardware Error]: running state: 0x1 [ 1419.602714][ C1] {57}[Hardware Error]: Power State Coordination Interface state: 0 [ 1419.602724][ C1] {57}[Hardware Error]: Error info structure 0: [ 1419.614797][ C1] {57}[Hardware Error]: num errors: 1 [ 1419.614804][ C1] {57}[Hardware Error]: error_type: 0, cache error [ 1419.629226][ C1] {57}[Hardware Error]: error_info: 0x0000000020400014 [ 1419.629234][ C1] {57}[Hardware Error]: cache level: 1 [ 1419.642006][ C1] {57}[Hardware Error]: the error has not been corrected [ 1419.642013][ C1] {57}[Hardware Error]: physical fault address: 0x0000001000093c00 [ 1419.654001][ C1] {57}[Hardware Error]: Vendor specific error info has 48 bytes: [ 1419.654014][ C1] {57}[Hardware Error]: 00000000: 00000000 00000000 00000000 00000000 ................

[PATCH OLK-5.10] [Backport] scsi: qla2xxx: Fix premature hw access after PCI error

22 Jan '26

From: Quinn Tran <qutran(a)marvell.com> stable inclusion from stable-v5.15.33 commit 5ef6319f9882699613d5182fbd7929b017e8c5ab category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/296 CVE: CVE-2022-49157 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit e35920ab7874d5e2faeb4f958a74bfa793f1ce5a upstream. After a recoverable PCI error has been detected and recovered, qla driver needs to check to see if the error condition still persist and/or wait for the OS to give the resume signal.

From: Bard Liao <yung-chuan.liao(a)linux.intel.com> stable inclusion from stable-v6.12.14 commit e012a77e4d7632cf615ba9625b1600ed8985c3b5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/30 CVE: CVE-2024-58012 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 569922b82ca660f8b24e705f6cf674e6b1f99cc7 ] Each cpu DAI should associate with a widget. However, the topology might not create the right number of DAI widgets for aggregated amps. And it will cause NULL pointer deference. Check that the DAI widget associated with the CPU DAI is valid to prevent NULL pointer deference due to missing DAI widgets in topologies with aggregated amps.
