[PATCH openEuler-1.0-LTS] i40e: Fix freeing of uninitialized misc IRQ vector
by Cui GaoSheng 31 May '24

31 May '24

From: Sylwester Dziedziuch <sylwesterx.dziedziuch(a)intel.com> stable inclusion from stable-v5.10.73 commit 97aeed72af4f83ae51534f0a2473ff52f8d66236 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9R4ON CVE: CVE-2021-47424 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 2e5a20573a926302b233b0c2e1077f5debc7ab2e ] When VSI set up failed in i40e_probe() as part of PF switch set up driver was trying to free misc IRQ vectors in i40e_clear_interrupt_scheme and produced a kernel Oops: Trying to free already-free IRQ 266 WARNING: CPU: 0 PID: 5 at kernel/irq/manage.c:1731 __free_irq+0x9a/0x300 Workqueue: events work_for_cpu_fn RIP: 0010:__free_irq+0x9a/0x300 Call Trace: ? synchronize_irq+0x3a/0xa0 free_irq+0x2e/0x60 i40e_clear_interrupt_scheme+0x53/0x190 [i40e] i40e_probe.part.108+0x134b/0x1a40 [i40e] ? kmem_cache_alloc+0x158/0x1c0 ? acpi_ut_update_ref_count.part.1+0x8e/0x345 ? acpi_ut_update_object_reference+0x15e/0x1e2 ? strstr+0x21/0x70 ? irq_get_irq_data+0xa/0x20 ? mp_check_pin_attr+0x13/0xc0 ? irq_get_irq_data+0xa/0x20 ? mp_map_pin_to_irq+0xd3/0x2f0 ? acpi_register_gsi_ioapic+0x93/0x170 ? pci_conf1_read+0xa4/0x100 ? pci_bus_read_config_word+0x49/0x70 ? do_pci_enable_device+0xcc/0x100 local_pci_probe+0x41/0x90 work_for_cpu_fn+0x16/0x20 process_one_work+0x1a7/0x360 worker_thread+0x1cf/0x390 ? create_worker+0x1a0/0x1a0 kthread+0x112/0x130 ? kthread_flush_work_fn+0x10/0x10 ret_from_fork+0x1f/0x40 The problem is that at that point misc IRQ vectors were not allocated yet and we get a call trace that driver is trying to free already free IRQ vectors. Add a check in i40e_clear_interrupt_scheme for __I40E_MISC_IRQ_REQUESTED PF state before calling i40e_free_misc_vector. This state is set only if misc IRQ vectors were properly initialized.

[PATCH OLK-5.10] x86/sgx: Break up long non-preemptible delays in sgx_vepc_release()
by Xiang Yang 31 May '24

From: Jack Wang <jinpu.wang(a)ionos.com> mainline inclusion from mainline-v6.6-rc1 commit 3d7d72a34e05b23e21bafc8bfb861e73c86b31f3 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9TZZB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- On large enclaves we hit the softlockup warning with following call trace: xa_erase() sgx_vepc_release() __fput() task_work_run() do_exit() The latency issue is similar to the one fixed in: 8795359e35bc ("x86/sgx: Silence softlockup detection when releasing large enclaves") The test system has 64GB of enclave memory, and all is assigned to a single VM. Release of 'vepc' takes a longer time and causes long latencies, which triggers the softlockup warning. Add cond_resched() to give other tasks a chance to run and reduce latencies, which also avoids the softlockup detector.

[PATCH openEuler-1.0-LTS] comedi: ni_usb6501: fix NULL-deref in command paths
by Cui GaoSheng 31 May '24

31 May '24

From: Johan Hovold <johan(a)kernel.org> stable inclusion from stable-v5.10.79 commit ef143dc0c3defe56730ecd3a9de7b3e1d7e557c1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RD2V CVE: CVE-2021-47476 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 907767da8f3a925b060c740e0b5c92ea7dbec440 upstream. The driver uses endpoint-sized USB transfer buffers but had no sanity checks on the sizes. This can lead to zero-size-pointer dereferences or overflowed transfer buffers in ni6501_port_command() and ni6501_counter_command() if a (malicious) device has smaller max-packet sizes than expected (or when doing descriptor fuzz testing). Add the missing sanity checks to probe().

Mike has a fix in that path for resv uncharge but it looks like the locking criteria was overlooked: hugetlb_cgroup_uncharge_folio_rsvd() will update the cgroup pointer, so it requires to be called with the lock held.
