[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

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-5.10] perf cpumap: Wrapper for CPU map indices
by Yushan Wang 30 Sep '24

30 Sep '24

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAQFZR CVE: NA ---------------------------------------------------------------------- Linux mainline changed the type of perf CPU map into struct perf_cpu to avoid confuses of CPU maps from cpu. The change affects a lot of infrastructures of Perf tool which this patchset depends on to fix perf undesirably scrutinizing events on offline CPUs issue[1]. This patch, with the purpose of adapting of following patches from Linux mainline to openeuler, is a mere copy of the patch [2] which changes the type of perf CPU map with careful refaction of affected code.

[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. Also, increase the timeout from 30 to 60 seconds to accommodate boot scripts requiring longer timeouts.

This issue arises when EHT-PHY capabilities shows support for a bandwidth and MCS-NSS set for that particular bandwidth is filled by zeros and due to this, driver obtains peer_nss as 0 and sending this value to firmware causes crash. Address this issue by implementing a validation step for the peer_nss value before passing it to the firmware. If the value is greater than zero, proceed with forwarding it to the firmware. However, if the value is invalid, reject the association request to prevent potential firmware crashes.

[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.

Adding the following warning ... WARN_ON_ONCE(msk->pm.add_addr_accepted == 0) ... before decrementing the add_addr_accepted counter helped to find a bug when running the "remove single subflow" subtest from the mptcp_join.sh selftest. Removing a 'subflow' endpoint will first trigger a RM_ADDR, then the subflow closure. Before this patch, and upon the reception of the RM_ADDR, the other peer will then try to decrement this add_addr_accepted. That's not correct because the attached subflows have not been created upon the reception of an ADD_ADDR. A way to solve that is to decrement the counter only if the attached subflow was an MP_JOIN to a remote id that was not 0, and initiated by the host receiving the RM_ADDR.

[PATCH OLK-5.10] KVM: arm64: Make ICC_*SGI*_EL1 undef in the absence of a vGICv3
by Zhang Zekun 29 Sep '24

29 Sep '24

From: Marc Zyngier <maz(a)kernel.org> stable inclusion from stable-v5.10.225 commit 15818af2f7aa55eff375333cb7689df15d3f24ef category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAR5D2 CVE: CVE-2024-46707 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------------------------- commit 3e6245ebe7ef341639e9a7e402b3ade8ad45a19f upstream. On a system with a GICv3, if a guest hasn't been configured with GICv3 and that the host is not capable of GICv2 emulation, a write to any of the ICC_*SGI*_EL1 registers is trapped to EL2. We therefore try to emulate the SGI access, only to hit a NULL pointer as no private interrupt is allocated (no GIC, remember?). The obvious fix is to give the guest what it deserves, in the shape of a UNDEF exception.
