[PATCH OLK-6.6] userfaultfd: don't BUG_ON() if khugepaged yanks our page table
by Liu Shixin 10 Oct '24

10 Oct '24

From: Jann Horn <jannh(a)google.com> stable inclusion from stable-v6.6.51 commit 4a594acc12d5954cdc71d4450a386748bf3d136a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9P2 CVE: CVE-2024-46838 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4828d207dc5161dc7ddf9a4f6dcfd80c7dd7d20a upstream. Since khugepaged was changed to allow retracting page tables in file mappings without holding the mmap lock, these BUG_ON()s are wrong - get rid of them. We could also remove the preceding "if (unlikely(...))" block, but then we could reach pte_offset_map_lock() with transhuge pages not just for file mappings but also for anonymous mappings - which would probably be fine but I think is not necessarily expected.

In walk_down_proc we also BUG_ON(refs == 0), which could happen if we have extent tree corruption. Change that to return -EUCLEAN. In do_walk_down() we catch this case and handle it correctly, however we return -EIO, which -EUCLEAN is a more appropriate error code.

[PATCH openEuler-1.0-LTS] platform/x86: panasonic-laptop: Fix SINF array out of bounds accesses
by Wupeng Ma 09 Oct '24

09 Oct '24

From: Hans de Goede <hdegoede(a)redhat.com> stable inclusion from stable-v6.6.52 commit 6821a82616f60aa72c5909b3e252ad97fb9f7e2a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAUA6B CVE: CVE-2024-46859 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f52e98d16e9bd7dd2b3aef8e38db5cbc9899d6a4 upstream. The panasonic laptop code in various places uses the SINF array with index values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array is big enough. Not all panasonic laptops have this many SINF array entries, for example the Toughbook CF-18 model only has 10 SINF array entries. So it only supports the AC+DC brightness entries and mute. Check that the SINF array has a minimum size which covers all AC+DC brightness entries and refuse to load if the SINF array is smaller. For higher SINF indexes hide the sysfs attributes when the SINF array does not contain an entry for that attribute, avoiding show()/store() accessing the array out of bounds and add bounds checking to the probe() and resume() code accessing these.

[PATCH OLK-6.6] cpufreq: intel_pstate: Revise global turbo disable check
by Yipeng Zou 09 Oct '24

09 Oct '24

From: Srinivas Pandruvada <srinivas.pandruvada(a)linux.intel.com> mainline inclusion from mainline-v6.7-rc1 commit 37b6ddba967c601479bea418a7ac6ff16b6232b7 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAVI54 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Setting global turbo flag based on CPU 0 P-state limits is problematic as it limits max P-state request on every CPU on the system just based on its P-state limits. There are two cases in which global.turbo_disabled flag is set: - When the MSR_IA32_MISC_ENABLE_TURBO_DISABLE bit is set to 1 in the MSR MSR_IA32_MISC_ENABLE. This bit can be only changed by the system BIOS before power up. - When the max non turbo P-state is same as max turbo P-state for CPU 0. The second check is not a valid to decide global turbo state based on the CPU 0. CPU 0 max turbo P-state can be same as max non turbo P-state, but for other CPUs this may not be true. There is no guarantee that max P-state limits are same for every CPU. This is possible that during fusing max P-state for a CPU is constrained. Also with the Intel Speed Select performance profile, CPU 0 may not be present in all profiles. In this case the max non turbo and turbo P-state can be set to the lowest possible P-state by the hardware when switched to such profile. Since max non turbo and turbo P-state is same, global.turbo_disabled flag will be set. Once global.turbo_disabled is set, any scaling max and min frequency update for any CPU will result in its max P-state constrained to the max non turbo P-state. Hence remove the check of max non turbo P-state equal to max turbo P-state of CPU 0 to set global turbo disabled flag.

[PATCH OLK-6.6] mptcp: pm: Fix uaf in __timer_delete_sync
by Wang Liang 09 Oct '24

From: Edward Adam Davis <eadavis(a)qq.com> stable inclusion from stable-v6.6.52 commit 6452b162549c7f9ef54655d3fb9977b9192e6e5b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAU9JW CVE: CVE-2024-46858 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit b4cd80b0338945a94972ac3ed54f8338d2da2076 upstream. There are two paths to access mptcp_pm_del_add_timer, result in a race condition: CPU1 CPU2 ==== ==== net_rx_action napi_poll netlink_sendmsg __napi_poll netlink_unicast process_backlog netlink_unicast_kernel __netif_receive_skb genl_rcv __netif_receive_skb_one_core netlink_rcv_skb NF_HOOK genl_rcv_msg ip_local_deliver_finish genl_family_rcv_msg ip_protocol_deliver_rcu genl_family_rcv_msg_doit tcp_v4_rcv mptcp_pm_nl_flush_addrs_doit tcp_v4_do_rcv mptcp_nl_remove_addrs_list tcp_rcv_established mptcp_pm_remove_addrs_and_subflows tcp_data_queue remove_anno_list_by_saddr mptcp_incoming_options mptcp_pm_del_add_timer mptcp_pm_del_add_timer kfree(entry) In remove_anno_list_by_saddr(running on CPU2), after leaving the critical zone protected by "pm.lock", the entry will be released, which leads to the occurrence of uaf in the mptcp_pm_del_add_timer(running on CPU1). Keeping a reference to add_timer inside the lock, and calling sk_stop_timer_sync() with this reference, instead of "entry->add_timer". Move list_del(&entry->list) to mptcp_pm_del_add_timer and inside the pm lock, do not directly access any members of the entry outside the pm lock, which can avoid similar "entry->x" uaf.

[PATCH openEuler-22.03-LTS-SP1] perf/x86/intel: Limit the period on Haswell
by Li Huafei 08 Oct '24

08 Oct '24

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! WARNING: CPU: 31 PID: 32438 at arch/x86/events/intel/core.c:3174 intel_pmu_handle_irq+0x285/0x370 Call Trace: <NMI> ? __warn+0xa4/0x220 ? intel_pmu_handle_irq+0x285/0x370 ? __report_bug+0x123/0x130 ? intel_pmu_handle_irq+0x285/0x370 ? __report_bug+0x123/0x130 ? intel_pmu_handle_irq+0x285/0x370 ? report_bug+0x3e/0xa0 ? handle_bug+0x3c/0x70 ? exc_invalid_op+0x18/0x50 ? asm_exc_invalid_op+0x1a/0x20 ? irq_work_claim+0x1e/0x40 ? intel_pmu_handle_irq+0x285/0x370 perf_event_nmi_handler+0x3d/0x60 nmi_handle+0x104/0x330 Thanks to Thomas Gleixner's analysis, the issue is caused by the low initial period (1) of the frequency estimation algorithm, which triggers the defects of the HW, specifically erratum HSW11 and HSW143. (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-6.6] sysctl: always initialize i_uid/i_gid

From: Thomas Weißschuh <linux(a)weissschuh.net> stable inclusion from stable-v6.6.44 commit ffde3af4b29bf97d62d82e1d45275587e10a991a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAKQ93 CVE: CVE-2024-42312 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- [ Upstream commit 98ca62ba9e2be5863c7d069f84f7166b45a5b2f4 ] Always initialize i_uid/i_gid inside the sysfs core so set_ownership() can safely skip setting them. Commit 5ec27ec735ba ("fs/proc/proc_sysctl.c: fix the default values of i_uid/i_gid on /proc/sys inodes.") added defaults for i_uid/i_gid when set_ownership() was not implemented. It also missed adjusting net_ctl_set_ownership() to use the same default values in case the computation of a better value failed.

[PATCH OLK-5.10] serial: sc16is7xx: fix invalid FIFO access with special register set
by Gu Bowen 08 Oct '24

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

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.

[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.

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.
