[PATCH OLK-6.6 v3] arm64: Do not enable hardware xcall/xint in guest temporarily
by Jinjie Ruan 18 Sep '25

18 Sep '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/release-management/issues/IBV2E4 -------------------------------- In guest VM, ID register is needed to do VM migration, but currently 920G do not have an ID register to identify hardware xcall/xint feature, which will be supported by AIDR_EL1.xcall in the next generation, so check the bit for non-920G hardware and do not enable xcall/xint in guest for 920G to avoid the problem in guest.

[PATCH OLK-6.6] vsock/virtio: Validate length in packet header before skb_put()
by Ziming Du 17 Sep '25

17 Sep '25

From: Will Deacon <will(a)kernel.org> mainline inclusion from mainline-v6.17-rc1 commit 0dab92484474587b82e8e0455839eaf5ac7bf894 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICWO1M CVE: CVE-2025-39718 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- When receiving a vsock packet in the guest, only the virtqueue buffer size is validated prior to virtio_vsock_skb_rx_put(). Unfortunately, virtio_vsock_skb_rx_put() uses the length from the packet header as the length argument to skb_put(), potentially resulting in SKB overflow if the host has gone wonky. Validate the length as advertised by the packet header before calling virtio_vsock_skb_rx_put().

[PATCH OLK-5.10] trace/fgraph: Fix error handling
by Tengda Wu 16 Sep '25

16 Sep '25

From: Guenter Roeck <linux(a)roeck-us.net> mainline inclusion from mainline-v6.17-rc4 commit ab1396af7595e7d49a3850481b24d7fe7cbdfd31 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICYBCS Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Commit edede7a6dcd7 ("trace/fgraph: Fix the warning caused by missing unregister notifier") added a call to unregister the PM notifier if register_ftrace_graph() failed. It does so unconditionally. However, the PM notifier is only registered with the first call to register_ftrace_graph(). If the first registration was successful and a subsequent registration failed, the notifier is now unregistered even if ftrace graphs are still registered. Fix the problem by only unregistering the PM notifier during error handling if there are no active fgraph registrations.
