[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.

[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.

[PATCH OLK-6.6] btrfs: fix race between direct IO write and fsync when using same fd
by Xiongfeng Wang 27 Sep '24

From: Filipe Manana <fdmanana(a)suse.com> stable inclusion from stable-v6.6.51 commit 7b5595f33c3c273613b590892a578d78186bb400 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IARY1Z CVE: CVE-2024-46734 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit cd9253c23aedd61eb5ff11f37a36247cd46faf86 upstream. If we have 2 threads that are using the same file descriptor and one of them is doing direct IO writes while the other is doing fsync, we have a race where we can end up either: 1) Attempt a fsync without holding the inode's lock, triggering an assertion failures when assertions are enabled; 2) Do an invalid memory access from the fsync task because the file private points to memory allocated on stack by the direct IO task and it may be used by the fsync task after the stack was destroyed. The race happens like this: 1) A user space program opens a file descriptor with O_DIRECT; 2) The program spawns 2 threads using libpthread for example; 3) One of the threads uses the file descriptor to do direct IO writes, while the other calls fsync using the same file descriptor. 4) Call task A the thread doing direct IO writes and task B the thread doing fsyncs; 5) Task A does a direct IO write, and at btrfs_direct_write() sets the file's private to an on stack allocated private with the member 'fsync_skip_inode_lock' set to true; 6) Task B enters btrfs_sync_file() and sees that there's a private structure associated to the file which has 'fsync_skip_inode_lock' set to true, so it skips locking the inode's VFS lock; 7) Task A completes the direct IO write, and resets the file's private to NULL since it had no prior private and our private was stack allocated. Then it unlocks the inode's VFS lock; 8) Task B enters btrfs_get_ordered_extents_for_logging(), then the assertion that checks the inode's VFS lock is held fails, since task B never locked it and task A has already unlocked it.

This issue, triggering the assertion, was observed with QEMU workloads by two users in the Link tags below. Fix this by not relying on a file's private to pass information to fsync that it should skip locking the inode and instead pass this information through a special value stored in current->journal_info. This is safe because in the relevant section of the direct IO write path we are not holding a transaction handle, so current->journal_info is NULL. The following C program triggers the issue: $ cat repro.c /* Get the O_DIRECT definition. */ #ifndef _GNU_SOURCE #define _GNU_SOURCE #endif #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <stdint.h> #include <fcntl.h> #include <errno.h> #include <string.h> #include <pthread.h> static int fd; static ssize_t do_write(int fd, const void *buf, size_t count, off_t offset) { while (count > 0) { ssize_t ret; ret = pwrite(fd, buf, count, offset); if (ret < 0) { if (errno == EINTR) continue; return ret; } count -= ret; buf += ret; } return 0; } static void *fsync_loop(void *arg) { while (1) { int ret; ret = fsync(fd); if (ret != 0) { perror("Fsync failed"); exit(6); } } } int main(int argc, char *argv[]) { long pagesize; void *write_buf; pthread_t fsyncer; int ret; if (argc != 2) { fprintf(stderr, "Use: %s <file path>\n", argv[0]); return 1; } fd = open(argv[1], O_WRONLY | O_CREAT | O_TRUNC | O_DIRECT, 0666); if (fd == -1) { perror("Failed to open/create file"); return 1; } pagesize = sysconf(_SC_PAGE_SIZE); if (pagesize == -1) { perror("Failed to get page size"); return 2; } ret = posix_memalign(&write_buf, pagesize, pagesize); if (ret) { perror("Failed to allocate buffer"); return 3; } ret = pthread_create(&fsyncer, NULL, fsync_loop, NULL); if (ret != 0) { fprintf(stderr, "Failed to create writer thread: %d\n", ret); return 4; } while (1) { ret = do_write(fd, write_buf, pagesize, 0); if (ret != 0) { perror("Write failed"); exit(5); } } return 0; } $ mkfs.btrfs -f /dev/sdi $ mount /dev/sdi /mnt/sdi $ timeout 10 ./repro /mnt/sdi/foo Usually the race is triggered within less than 1 second.

From: Paulo Alcantara <pc(a)manguebit.com> stable inclusion from stable-v6.6.51 commit 5a72d1edb0843e4c927a4096f81e631031c25c28 category: kasan bugzilla: https://gitee.com/src-openeuler/kernel/issues/IARWCG CVE: CVE-2024-46796 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f9c169b51b6ce20394594ef674d6b10efba31220 upstream. If smb2_compound_op() is called with a valid @cfile and returned -EINVAL, we need to call cifs_get_writable_path() before retrying it as the reference of @cfile was already dropped by previous call.

From: Olivier Sobrie <olivier(a)sobrie.be> stable inclusion from stable-v6.6.51 commit 60dc4ee0428d70bcbb41436b6729d29f1cbdfb89 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IARV9S?from=project-issue CVE: CVE-2024-46746 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 97155021ae17b86985121b33cf8098bcde00d497 ] HID driver callbacks aren't called anymore once hid_destroy_device() has been called.
