[PATCH openEuler-22.03-LTS-SP1] perf/x86/intel: Limit the period on Haswell

From: Kan Liang <kan.liang(a)linux.intel.com> mainline inclusion from mainline-v6.11-rc7 commit 25dfc9e357af8aed1ca79b318a73f2c59c1f0b2b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAR511 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Running the ltp test cve-2015-3290 concurrently reports the following warnings. perfevents: irq loop stuck!

(For the details, please refer https://lore.kernel.org/lkml/87plq9l5d2.ffs@tglx/) The HSW11 requires a period larger than 100 for the INST_RETIRED.ALL event, but the initial period in the freq mode is 1. The erratum is the same as the BDM11, which has been supported in the kernel. A minimum period of 128 is enforced as well on HSW. HSW143 is regarding that the fixed counter 1 may overcount 32 with the Hyper-Threading is enabled. However, based on the test, the hardware has more issues than it tells. Besides the fixed counter 1, the message 'interrupt took too long' can be observed on any counter which was armed with a period < 32 and two events expired in the same NMI. A minimum period of 32 is enforced for the rest of the events. The recommended workaround code of the HSW143 is not implemented. Because it only addresses the issue for the fixed counter. It brings extra overhead through extra MSR writing. No related overcounting issue has been reported so far.

[PATCH openEuler-22.03-LTS-SP1] [Backport] s390/dasd: fix error recovery leading to data corruption on ESE devices

From: Stefan Haberland <sth(a)linux.ibm.com> stable inclusion from stable-v5.10.225 commit e245a18281c252c8dbc467492e09bb5d4b012118 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAQOID CVE: CVE-2024-45026 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 7db4042336580dfd75cb5faa82c12cd51098c90b upstream. Extent Space Efficient (ESE) or thin provisioned volumes need to be formatted on demand during usual IO processing. The dasd_ese_needs_format function checks for error codes that signal the non existence of a proper track format. The check for incorrect length is to imprecise since other error cases leading to transport of insufficient data also have this flag set. This might lead to data corruption in certain error cases for example during a storage server warmstart. Fix by removing the check for incorrect length and replacing by explicitly checking for invalid track format in transport mode. Also remove the check for file protected since this is not a valid ESE handling case.

[PATCH OLK-5.10] serial: sc16is7xx: fix invalid FIFO access with special register set

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> mainline inclusion from mainline-v6.11-rc3 commit 7d3b793faaab1305994ce568b59d61927235f57b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAOY1A CVE: CVE-2024-44950 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- When enabling access to the special register set, Receiver time-out and RHR interrupts can happen. In this case, the IRQ handler will try to read from the FIFO thru the RHR register at address 0x00, but address 0x00 is mapped to DLL register, resulting in erroneous FIFO reading. Call graph example: sc16is7xx_startup(): entry sc16is7xx_ms_proc(): entry sc16is7xx_set_termios(): entry sc16is7xx_set_baud(): DLH/DLL = $009C --> access special register set sc16is7xx_port_irq() entry --> IIR is 0x0C sc16is7xx_handle_rx() entry sc16is7xx_fifo_read(): --> unable to access FIFO (RHR) because it is mapped to DLL (LCR=LCR_CONF_MODE_A) sc16is7xx_set_baud(): exit --> Restore access to general register set Fix the problem by claiming the efr_lock mutex when accessing the Special register set.

(For the details, please refer https://lore.kernel.org/lkml/87plq9l5d2.ffs@tglx/) The HSW11 requires a period larger than 100 for the INST_RETIRED.ALL event, but the initial period in the freq mode is 1. The erratum is the same as the BDM11, which has been supported in the kernel. A minimum period of 128 is enforced as well on HSW. HSW143 is regarding that the fixed counter 1 may overcount 32 with the Hyper-Threading is enabled. However, based on the test, the hardware has more issues than it tells. Besides the fixed counter 1, the message 'interrupt took too long' can be observed on any counter which was armed with a period < 32 and two events expired in the same NMI. A minimum period of 32 is enforced for the rest of the events. The recommended workaround code of the HSW143 is not implemented. Because it only addresses the issue for the fixed counter. It brings extra overhead through extra MSR writing. No related overcounting issue has been reported so far.

[PATCH OLK-6.6] dma-buf: heaps: Fix off-by-one in CMA heap fault handler
by Xiongfeng Wang 07 Oct '24

07 Oct '24

From: "T.J. Mercier" <tjmercier(a)google.com> stable inclusion from stable-v6.6.52 commit eb7fc8b65cea22f9038c52398c8b22849e9620ea category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9M8 CVE: CVE-2024-46852 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit ea5ff5d351b520524019f7ff7f9ce418de2dad87 upstream. Until VM_DONTEXPAND was added in commit 1c1914d6e8c6 ("dma-buf: heaps: Don't track CMA dma-buf pages under RssFile") it was possible to obtain a mapping larger than the buffer size via mremap and bypass the overflow check in dma_buf_mmap_internal. When using such a mapping to attempt to fault past the end of the buffer, the CMA heap fault handler also checks the fault offset against the buffer size, but gets the boundary wrong by 1. Fix the boundary check so that we don't read off the end of the pages array and insert an arbitrary page in the mapping. Reported-by: Xingyu Jin <xingyuj(a)google.com> Fixes: a5d2d29e24be ("dma-buf: heaps: Move heap-helper logic into the cma_heap implementation") Cc: stable(a)vger.kernel.org # Applicable >= 5.10.

[PATCH OLK-6.6] dma-buf: heaps: Fix off-by-one in CMA heap fault handler

From: "T.J. Mercier" <tjmercier(a)google.com> mainline inclusion from mainline-v6.11 commit ea5ff5d351b520524019f7ff7f9ce418de2dad87 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9M8 CVE: CVE-2024-46852 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Until VM_DONTEXPAND was added in commit 1c1914d6e8c6 ("dma-buf: heaps: Don't track CMA dma-buf pages under RssFile") it was possible to obtain a mapping larger than the buffer size via mremap and bypass the overflow check in dma_buf_mmap_internal. When using such a mapping to attempt to fault past the end of the buffer, the CMA heap fault handler also checks the fault offset against the buffer size, but gets the boundary wrong by 1. Fix the boundary check so that we don't read off the end of the pages array and insert an arbitrary page in the mapping.

[PATCH OLK-6.6] spi: rockchip: Resolve unbalanced runtime PM / system PM handling

From: Brian Norris <briannorris(a)chromium.org> stable inclusion from stable-v6.6.51 commit d034bff62faea1a2219e0d2f3d17263265f24087 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9NV CVE: CVE-2024-46846 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit be721b451affbecc4ba4eaac3b71cdbdcade1b1b upstream. Commit e882575efc77 ("spi: rockchip: Suspend and resume the bus during NOIRQ_SYSTEM_SLEEP_PM ops") stopped respecting runtime PM status and simply disabled clocks unconditionally when suspending the system. This causes problems when the device is already runtime suspended when we go to sleep -- in which case we double-disable clocks and produce a WARNing. Switch back to pm_runtime_force_{suspend,resume}(), because that still seems like the right thing to do, and the aforementioned commit makes no explanation why it stopped using it. Also, refactor some of the resume() error handling, because it's not actually a good idea to re-disable clocks on failure.

[PATCH OLK-6.6] scsi: lpfc: Handle mailbox timeouts in lpfc_get_sfp_info
by Zheng Qixing 30 Sep '24

30 Sep '24

From: Justin Tee <justin.tee(a)broadcom.com> mainline inclusion from mainline-v6.11-rc1 commit ede596b1434b57c0b3fd5c02b326efe5c54f6e48 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9N8 CVE: CVE-2024-46842 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The MBX_TIMEOUT return code is not handled in lpfc_get_sfp_info and the routine unconditionally frees submitted mailbox commands regardless of return status. The issue is that for MBX_TIMEOUT cases, when firmware returns SFP information at a later time, that same mailbox memory region references previously freed memory in its cmpl routine. Fix by adding checks for the MBX_TIMEOUT return code. During mailbox resource cleanup, check the mbox flag to make sure that the wait did not timeout. If the MBOX_WAKE flag is not set, then do not free the resources because it will be freed when firmware completes the mailbox at a later time in its cmpl routine.
