Specifically, a VMA which has a valid pointer to vma->vm_userfaultfd_ctx, but no UFFD flags in vma->vm_flags. The inconsistency is caused in ksm_madvise(): when user calls madvise() with MADV_UNMEARGEABLE on a VMA that is registered for UFFD in MINOR mode, it accidentally clears all flags stored in the upper 32 bits of vma->vm_flags. Assuming x86_64 kernel build, unsigned long is 64-bit and unsigned int and int are 32-bit wide. This setup causes the following mishap during the &= ~VM_MERGEABLE assignment. VM_MERGEABLE is a 32-bit constant of type unsigned int, 0x8000'0000. After ~ is applied, it becomes 0x7fff'ffff unsigned int, which is then promoted to unsigned long before the & operation. This promotion fills upper 32 bits with leading 0s, as we're doing unsigned conversion (and even for a signed conversion, this wouldn't help as the leading bit is 0). & operation thus ends up AND-ing vm_flags with 0x0000'0000'7fff'ffff instead of intended 0xffff'ffff'7fff'ffff and hence accidentally clears the upper 32-bits of its value. Fix it by changing `VM_MERGEABLE` constant to unsigned long, using the BIT() macro. Note: other VM_* flags are not affected: This only happens to the VM_MERGEABLE flag, as the other VM_* flags are all constants of type int and after ~ operation, they end up with leading 1 and are thus converted to unsigned long with leading 1s. Note 2: After commit 31defc3b01d9 ("userfaultfd: remove (VM_)BUG_ON()s"), this is no longer a kernel BUG, but a WARNING at the same place: [ 45.595973] WARNING: CPU: 1 PID: 2474 at mm/userfaultfd.c:2067 but the root-cause (flag-drop) remains the same.

[PATCH 1/1] selftest/sched: skip the test if smt is not enabled

by Yifei Liu

The core scheduling is for smt enabled cpus. It is not returns failure and gives plenty of error messages and not clearly points to the smt issue if the smt is disabled. It just mention "not a core sched system" and many other messages. For example: Not a core sched system tid=210574, / tgid=210574 / pgid=210574: ffffffffffffffff Not a core sched system tid=210575, / tgid=210575 / pgid=210574: ffffffffffffffff Not a core sched system tid=210577, / tgid=210575 / pgid=210574: ffffffffffffffff (similar things many other times) In this patch, the test will first read /sys/devices/system/cpu/smt/active, if the file cannot be opened or its value is 0, the test is skipped with an explanatory message. This helps developers understand why it is skipped and avoids unnecessary attention when running the full selftest suite.

KVM: arm64: Regression in at least linux-6.1.y tree with recent FPSIMD/SVE/SME fix

by Kenneth Van Alstyne

Greetings: Sending via plain text email -- apologies if you receive this twice. If this isn't the process for reporting a regression in a LTS kernel per https://www.kernel.org/doc/html/latest/admin-guide/reporting-issues.html, I'm happy to follow another process. Kernel 6.1.149 introduced a regression, at least on our ARM Cortex A57-based platforms, via commit 8f4dc4e54eed4bebb18390305eb1f721c00457e1 in arch/arm64/kernel/fpsimd.c where booting KVM VMs eventually leads to a spinlock recursion BUG and crash of the box. Reverting that commit via the below reverts to the old (working) behavior: diff --git a/arch/arm64/kernel/fpsimd.c b/arch/arm64/kernel/fpsimd.c index 837d1937300a57..bc42163a7fd1f0 100644 --- a/arch/arm64/kernel/fpsimd.c +++ b/arch/arm64/kernel/fpsimd.c @@ -1851,10 +1851,10 @@ void fpsimd_save_and_flush_cpu_state(void) if (!system_supports_fpsimd()) return; WARN_ON(preemptible()); - get_cpu_fpsimd_context(); + __get_cpu_fpsimd_context(); fpsimd_save(); fpsimd_flush_cpu_state(); - put_cpu_fpsimd_context(); + __put_cpu_fpsimd_context(); } #ifdef CONFIG_KERNEL_MODE_NEON It's not entirely clear to me if this is specific to our firmware, specific to ARM Cortex A57, or more systemic as we lack sufficiently differentiated hardware to know. I've tested on the latest 6.1 kernel in addition to the one in the log below and have also tested a number of firmware versions available for these boxes.

[PATCH] nvme-tcp: fix usage of page_frag_cache

by Dmitry Bogdanov

nvme uses page_frag_cache to preallocate PDU for each preallocated request of block device. Block devices are created in parallel threads, consequently page_frag_cache is used in not thread-safe manner. That leads to incorrect refcounting of backstore pages and premature free. That can be catched by !sendpage_ok inside network stack: WARNING: CPU: 7 PID: 467 at ../net/core/skbuff.c:6931 skb_splice_from_iter+0xfa/0x310. tcp_sendmsg_locked+0x782/0xce0 tcp_sendmsg+0x27/0x40 sock_sendmsg+0x8b/0xa0 nvme_tcp_try_send_cmd_pdu+0x149/0x2a0 Then random panic may occur. Fix that by serializing the usage of page_frag_cache.
