[PATCH OLK-6.6] bpf: Check rcu_read_lock_trace_held() in bpf_map_lookup_percpu_elem()

From: Hou Tao <houtao1(a)huawei.com> stable inclusion from stable-v6.6.95 commit 7bf4461f1c97207fda757014690d55a447ce859f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICK4OG CVE: CVE-2025-38022 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit d4965578267e2e81f67c86e2608481e77e9c8569 ] bpf_map_lookup_percpu_elem() helper is also available for sleepable bpf program. When BPF JIT is disabled or under 32-bit host, bpf_map_lookup_percpu_elem() will not be inlined. Using it in a sleepable bpf program will trigger the warning in bpf_map_lookup_percpu_elem(), because the bpf program only holds rcu_read_lock_trace lock. Therefore, add the missed check.

[PATCH OLK-6.6 v2] mm: respect mmap hint address when aligning for THP
by Tong Tiangen 07 Jul '25

07 Jul '25

From: Kalesh Singh <kaleshsingh(a)google.com> mainline inclusion from mainline-v6.13-rc2 commit 249608ee47132cab3b1adacd9e463548f57bd316 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICK7OL Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP boundaries") updated __get_unmapped_area() to align the start address for the VMA to a PMD boundary if CONFIG_TRANSPARENT_HUGEPAGE=y. It does this by effectively looking up a region that is of size, request_size + PMD_SIZE, and aligning up the start to a PMD boundary. Commit 4ef9ad19e176 ("mm: huge_memory: don't force huge page alignment on 32 bit") opted out of this for 32bit due to regressions in mmap base randomization. Commit d4148aeab412 ("mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes") restricted this to only mmap sizes that are multiples of the PMD_SIZE due to reported regressions in some performance benchmarks -- which seemed mostly due to the reduced spatial locality of related mappings due to the forced PMD-alignment. Another unintended side effect has emerged: When a user specifies an mmap hint address, the THP alignment logic modifies the behavior, potentially ignoring the hint even if a sufficiently large gap exists at the requested hint location. Example Scenario: Consider the following simplified virtual address (VA) space: ... 0x200000-0x400000 --- VMA A 0x400000-0x600000 --- Hole 0x600000-0x800000 --- VMA B ... A call to mmap() with hint=0x400000 and len=0x200000 behaves differently: - Before THP alignment: The requested region (size 0x200000) fits into the gap at 0x400000, so the hint is respected. - After alignment: The logic searches for a region of size 0x400000 (len + PMD_SIZE) starting at 0x400000. This search fails due to the mapping at 0x600000 (VMA B), and the hint is ignored, falling back to arch_get_unmapped_area[_topdown](). In general the hint is effectively ignored, if there is any existing mapping in the below range: [mmap_hint + mmap_size, mmap_hint + mmap_size + PMD_SIZE) This changes the semantics of mmap hint; from ""Respect the hint if a sufficiently large gap exists at the requested location" to "Respect the hint only if an additional PMD-sized gap exists beyond the requested size". This has performance implications for allocators that allocate their heap using mmap but try to keep it "as contiguous as possible" by using the end of the exisiting heap as the address hint. With the new behavior it's more likely to get a much less contiguous heap, adding extra fragmentation and performance overhead. To restore the expected behavior; don't use thp_get_unmapped_area_vmflags() when the user provided a hint address, for anonymous mappings. Note: As Yang Shi pointed out: the issue still remains for filesystems which are using thp_get_unmapped_area() for their get_unmapped_area() op. It is unclear what worklaods will regress for if we ignore THP alignment when the hint address is provided for such file backed mappings -- so this fix will be handled separately.

[PATCH OLK-6.6] octeon_ep: Fix host hang issue during device reboot

From: Sathesh B Edara <sedara(a)marvell.com> stable inclusion from stable-v6.6.90 commit 7e1ca1bed3f66e00377f7d2147be390144924276 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC991M CVE: CVE-2025-37933 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 34f42736b325287a7b2ce37e415838f539767bda ] When the host loses heartbeat messages from the device, the driver calls the device-specific ndo_stop function, which frees the resources. If the driver is unloaded in this scenario, it calls ndo_stop again, attempting to free resources that have already been freed, leading to a host hang issue. To resolve this, dev_close should be called instead of the device-specific stop function.dev_close internally calls ndo_stop to stop the network interface and performs additional cleanup tasks. During the driver unload process, if the device is already down, ndo_stop is not called.

[PATCH OLK-6.6] arm64/mpam: Fix L2 monitor issue under CDP mode
by Zeng Heng 07 Jul '25

07 Jul '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IC30P1 -------------------------------- The L2 monitor counters always reset to 0 under CDP working mode. This occurs because the L2 monitor employs cumulative statistics, and monitors a single partid within each statistical cycle. After completing the configuration for the new partid monitoring, the monitor instance starts a new monitoring cycle and resets the counter to zero. Since MPAM implements the CDP feature by allocating two partids, switching the monitor's target partid during a monitoring cycle falsely triggers a "new control group" assumption, leading to erroneous counter resets. To resolve this, use the real partid % num_mon to ensure distinct monitor instances track different partids under the CDP control group, preventing unintended resets.

The possible case should be in f2fs_do_truncate_blocks(), we try to truncate inode size to zero, however, dn.ofs_in_node is zero and dn.node_page is not an inode page, so it fails to truncate inode page, and then pass zeroed free_from to f2fs_truncate_inode_blocks(), result in this issue. if (dn.ofs_in_node || IS_INODE(dn.node_page)) { f2fs_truncate_data_blocks_range(&dn, count); free_from += count; } I guess the reason why dn.node_page is not an inode page could be: there are multiple nat entries share the same node block address, once the node block address was reused, f2fs_get_node_page() may load a non-inode block. Let's add a sanity check for such condition to avoid out-of-bounds access issue.

Because jiffies are never updated, as we are in a context with interrupts disabled, we never exit that loop and have a deadlock. That deadlock was noticed on a sama5d4 device that stayed locked for days. Use retries instead of jiffies so that the timeout really works and we do not have a deadlock anymore.

[PATCH OLK-6.6] mm: respect mmap hint address when aligning for THP
by Tong Tiangen 07 Jul '25

07 Jul '25

From: Kalesh Singh <kaleshsingh(a)google.com> mainline inclusion from mainline-v6.13-rc2 commit 249608ee47132cab3b1adacd9e463548f57bd316 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICK7OL Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP boundaries") updated __get_unmapped_area() to align the start address for the VMA to a PMD boundary if CONFIG_TRANSPARENT_HUGEPAGE=y. It does this by effectively looking up a region that is of size, request_size + PMD_SIZE, and aligning up the start to a PMD boundary. Commit 4ef9ad19e176 ("mm: huge_memory: don't force huge page alignment on 32 bit") opted out of this for 32bit due to regressions in mmap base randomization. Commit d4148aeab412 ("mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes") restricted this to only mmap sizes that are multiples of the PMD_SIZE due to reported regressions in some performance benchmarks -- which seemed mostly due to the reduced spatial locality of related mappings due to the forced PMD-alignment. Another unintended side effect has emerged: When a user specifies an mmap hint address, the THP alignment logic modifies the behavior, potentially ignoring the hint even if a sufficiently large gap exists at the requested hint location. Example Scenario: Consider the following simplified virtual address (VA) space: ... 0x200000-0x400000 --- VMA A 0x400000-0x600000 --- Hole 0x600000-0x800000 --- VMA B ... A call to mmap() with hint=0x400000 and len=0x200000 behaves differently: - Before THP alignment: The requested region (size 0x200000) fits into the gap at 0x400000, so the hint is respected. - After alignment: The logic searches for a region of size 0x400000 (len + PMD_SIZE) starting at 0x400000. This search fails due to the mapping at 0x600000 (VMA B), and the hint is ignored, falling back to arch_get_unmapped_area[_topdown](). In general the hint is effectively ignored, if there is any existing mapping in the below range: [mmap_hint + mmap_size, mmap_hint + mmap_size + PMD_SIZE) This changes the semantics of mmap hint; from ""Respect the hint if a sufficiently large gap exists at the requested location" to "Respect the hint only if an additional PMD-sized gap exists beyond the requested size". This has performance implications for allocators that allocate their heap using mmap but try to keep it "as contiguous as possible" by using the end of the exisiting heap as the address hint. With the new behavior it's more likely to get a much less contiguous heap, adding extra fragmentation and performance overhead. To restore the expected behavior; don't use thp_get_unmapped_area_vmflags() when the user provided a hint address, for anonymous mappings. Note: As Yang Shi pointed out: the issue still remains for filesystems which are using thp_get_unmapped_area() for their get_unmapped_area() op. It is unclear what worklaods will regress for if we ignore THP alignment when the hint address is provided for such file backed mappings -- so this fix will be handled separately.

If this happens in the middle of a concurrent gup_fast(), gup_fast() could end up walking the page tables of another process. While I don't see any way in which that immediately leads to kernel memory corruption, it is really weird and unexpected. Fix it with an explicit broadcast IPI through tlb_remove_table_sync_one(), just like we do in khugepaged when removing page tables for a THP collapse.

[PATCH OLK-6.6] crypto: ecdsa - Harden against integer overflows in DIV_ROUND_UP()

Herbert instead suggests (for a division by 8): X / 8 + !!(X & 7) Based on this formula, introduce a generic DIV_ROUND_UP_POW2() macro and use it in lieu of DIV_ROUND_UP() for ->key_size() return values. Additionally, use the macro in ecc_digits_from_bytes(), whose "nbytes" parameter is a ->key_size() return value in some instances, or a user-specified ASN.1 length in the case of ecdsa_get_signature_rs().

[PATCH OLK-6.6] KVM: x86: Acquire SRCU in KVM_GET_MP_STATE to protect guest memory accesses

From: Sean Christopherson <seanjc(a)google.com> stable inclusion from stable-v6.6.88 commit 8a3df0aa1087a89f5ce55f4aba816bfcb1ecf1be category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IC8J7I CVE: CVE-2025-23141 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit ef01cac401f18647d62720cf773d7bb0541827da upstream. Acquire a lock on kvm->srcu when userspace is getting MP state to handle a rather extreme edge case where "accepting" APIC events, i.e. processing pending INIT or SIPI, can trigger accesses to guest memory. If the vCPU is in L2 with INIT *and* a TRIPLE_FAULT request pending, then getting MP state will trigger a nested VM-Exit by way of ->check_nested_events(), and emuating the nested VM-Exit can access guest memory. The splat was originally hit by syzkaller on a Google-internal kernel, and reproduced on an upstream kernel by hacking the triple_fault_event_test selftest to stuff a pending INIT, store an MSR on VM-Exit (to generate a memory access on VMX), and do vcpu_mp_state_get() to trigger the scenario. ============================= WARNING: suspicious RCU usage 6.14.0-rc3-b112d356288b-vmx/pi_lockdep_false_pos-lock #3 Not tainted ----------------------------- include/linux/kvm_host.h:1058 suspicious rcu_dereference_check() usage! other info that might help us debug this: rcu_scheduler_active = 2, debug_locks = 1 1 lock held by triple_fault_ev/1256: #0: ffff88810df5a330 (&vcpu->mutex){+.+.}-{4:4}, at: kvm_vcpu_ioctl+0x8b/0x9a0 [kvm] stack backtrace: CPU: 11 UID: 1000 PID: 1256 Comm: triple_fault_ev Not tainted 6.14.0-rc3-b112d356288b-vmx #3 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 Call Trace: <TASK> dump_stack_lvl+0x7f/0x90 lockdep_rcu_suspicious+0x144/0x190 kvm_vcpu_gfn_to_memslot+0x156/0x180 [kvm] kvm_vcpu_read_guest+0x3e/0x90 [kvm] read_and_check_msr_entry+0x2e/0x180 [kvm_intel] __nested_vmx_vmexit+0x550/0xde0 [kvm_intel] kvm_check_nested_events+0x1b/0x30 [kvm] kvm_apic_accept_events+0x33/0x100 [kvm] kvm_arch_vcpu_ioctl_get_mpstate+0x30/0x1d0 [kvm] kvm_vcpu_ioctl+0x33e/0x9a0 [kvm] __x64_sys_ioctl+0x8b/0xb0 do_syscall_64+0x6c/0x170 entry_SYSCALL_64_after_hwframe+0x4b/0x53 </TASK> Cc: stable(a)vger.kernel.org Signed-off-by: Sean Christopherson <seanjc(a)google.com> Message-ID: <20250401150504.829812-1-seanjc(a)google.com> Signed-off-by: Paolo Bonzini <pbonzini(a)redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Wang Hai <wanghai38(a)huawei.com> Signed-off-by: Chen Ridong <chenridong(a)huawei.com> --- arch/x86/kvm/x86.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/arch/x86/kvm/x86.c b/arch/x86/kvm/x86.c index 3e9d6f368eed2..7864c501b312d 100644 --- a/arch/x86/kvm/x86.c +++ b/arch/x86/kvm/x86.c @@ -11553,6 +11553,8 @@ int kvm_arch_vcpu_ioctl_get_mpstate(struct kvm_vcpu *vcpu, if (kvm_mpx_supported()) kvm_load_guest_fpu(vcpu); + kvm_vcpu_srcu_read_lock(vcpu); + r = kvm_apic_accept_events(vcpu); if (r < 0) goto out; @@ -11566,6 +11568,8 @@ int kvm_arch_vcpu_ioctl_get_mpstate(struct kvm_vcpu *vcpu, mp_state->mp_state = vcpu->arch.mp_state; out: + kvm_vcpu_srcu_read_unlock(vcpu); + if (kvm_mpx_supported()) kvm_put_guest_fpu(vcpu); vcpu_put(vcpu); -- 2.34.1

[PATCH openEuler-1.0-LTS] usbnet: Fix linkwatch use-after-free on disconnect
by Dong Chenchen 05 Jul '25

05 Jul '25

From: Lukas Wunner <lukas(a)wunner.de> stable inclusion from stable-v4.19.256 commit 7f77dcbc030c2faa6d8e8a594985eeb34018409e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICG9RB CVE: CVE-2022-50220 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a69e617e533edddf3fa3123149900f36e0a6dc74 upstream. usbnet uses the work usbnet_deferred_kevent() to perform tasks which may sleep. On disconnect, completion of the work was originally awaited in ->ndo_stop(). But in 2003, that was moved to ->disconnect() by historic commit "[PATCH] USB: usbnet, prevent exotic rtnl deadlock": https://git.kernel.org/tglx/history/c/0f138bbfd83c The change was made because back then, the kernel's workqueue implementation did not allow waiting for a single work. One had to wait for completion of *all* work by calling flush_scheduled_work(), and that could deadlock when waiting for usbnet_deferred_kevent() with rtnl_mutex held in ->ndo_stop(). The commit solved one problem but created another: It causes a use-after-free in USB Ethernet drivers aqc111.c, asix_devices.c, ax88179_178a.c, ch9200.c and smsc75xx.c: * If the drivers receive a link change interrupt immediately before disconnect, they raise EVENT_LINK_RESET in their (non-sleepable) ->status() callback and schedule usbnet_deferred_kevent(). * usbnet_deferred_kevent() invokes the driver's ->link_reset() callback, which calls netif_carrier_{on,off}(). * That in turn schedules the work linkwatch_event(). Because usbnet_deferred_kevent() is awaited after unregister_netdev(), netif_carrier_{on,off}() may operate on an unregistered netdev and linkwatch_event() may run after free_netdev(), causing a use-after-free. In 2010, usbnet was changed to only wait for a single instance of usbnet_deferred_kevent() instead of *all* work by commit 23f333a2bfaf ("drivers/net: don't use flush_scheduled_work()"). Unfortunately the commit neglected to move the wait back to ->ndo_stop(). Rectify that omission at long last.

[PATCH openEuler-1.0-LTS] sch_hfsc: Fix qlen accounting bug when using peek in hfsc_enqueue()
by Dong Chenchen 05 Jul '25

05 Jul '25

From: Cong Wang <xiyou.wangcong(a)gmail.com> mainline inclusion from mainline-v6.15-rc6 commit 3f981138109f63232a5fb7165938d4c945cc1b9d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICDGN6 CVE: CVE-2025-38000 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When enqueuing the first packet to an HFSC class, hfsc_enqueue() calls the child qdisc's peek() operation before incrementing sch->q.qlen and sch->qstats.backlog. If the child qdisc uses qdisc_peek_dequeued(), this may trigger an immediate dequeue and potential packet drop. In such cases, qdisc_tree_reduce_backlog() is called, but the HFSC qdisc's qlen and backlog have not yet been updated, leading to inconsistent queue accounting. This can leave an empty HFSC class in the active list, causing further consequences like use-after-free. This patch fixes the bug by moving the increment of sch->q.qlen and sch->qstats.backlog before the call to the child qdisc's peek() operation. This ensures that queue length and backlog are always accurate when packet drops or dequeues are triggered during the peek.

If an error occures before this point then the unwind will call rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task() which will oops when trying to access the uninitialized spinlock. Move the spinlock initializations earlier before any failures.

[PATCH openEuler-1.0-LTS] iavf: Fix reset error handling

05 Jul '25

From: Przemyslaw Patynowski <przemyslawx.patynowski(a)intel.com> mainline inclusion from mainline-v6.0-rc2 commit 31071173771e079f7bc08dacd61e0db913262fbf category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICGABK CVE: CVE-2022-50053 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Do not call iavf_close in iavf_reset_task error handling. Doing so can lead to double call of napi_disable, which can lead to deadlock there. Removing VF would lead to iavf_remove task being stuck, because it requires crit_lock, which is held by iavf_close. Call iavf_disable_vf if reset fail, so that driver will clean up remaining invalid resources. During rapid VF resets, HW can fail to setup VF mailbox. Wrong error handling can lead to iavf_remove being stuck with: [ 5218.999087] iavf 0000:82:01.0: Failed to init adminq: -53 ...
