[PATCH v5 1/2] dma-mapping: benchmark: Restore padding to ensure uABI remained consistent

by Qinxin Xia

The padding field in the structure was previously reserved to maintain a stable interface for potential new fields, ensuring compatibility with user-space shared data structures. However,it was accidentally removed by tiantao in a prior commit, which may lead to incompatibility between user space and the kernel. This patch reinstates the padding to restore the original structure layout and preserve compatibility.

[PATCH v2 1/2] PCI: Allow per function PCI slots

by Farhan Ali

On s390 systems, which use a machine level hypervisor, PCI devices are always accessed through a form of PCI pass-through which fundamentally operates on a per PCI function granularity. This is also reflected in the s390 PCI hotplug driver which creates hotplug slots for individual PCI functions. Its reset_slot() function, which is a wrapper for zpci_hot_reset_device(), thus also resets individual functions. Currently, the kernel's PCI_SLOT() macro assigns the same pci_slot object to multifunction devices. This approach worked fine on s390 systems that only exposed virtual functions as individual PCI domains to the operating system. Since commit 44510d6fa0c0 ("s390/pci: Handling multifunctions") s390 supports exposing the topology of multifunction PCI devices by grouping them in a shared PCI domain. When attempting to reset a function through the hotplug driver, the shared slot assignment causes the wrong function to be reset instead of the intended one. It also leaks memory as we do create a pci_slot object for the function, but don't correctly free it in pci_slot_release(). Add a flag for struct pci_slot to allow per function PCI slots for functions managed through a hypervisor, which exposes individual PCI functions while retaining the topology.

[PATCH net] virtio-net: calculate header alignment mask based on features

by Jason Wang

Commit 56a06bd40fab ("virtio_net: enable gso over UDP tunnel support.") switches to check the alignment of the virtio_net_hdr_v1_hash_tunnel even when doing the transmission even if the feature is not negotiated. This will cause a series performance degradation of pktgen as the skb->data can't satisfy the alignment requirement due to the increase of the header size then virtio-net must prepare at least 2 sgs with indirect descriptors which will introduce overheads in the device. Fixing this by calculate the header alignment during probe so when tunnel gso is not negotiated, we can less strict. Pktgen in guest + XDP_DROP on TAP + vhost_net shows the TX PPS is recovered from 2.4Mpps to 4.45Mpps. Note that we still need a way to recover the performance when tunnel gso is enabled, probably a new vnet header format. Fixes: 56a06bd40fab ("virtio_net: enable gso over UDP tunnel support.")

[PATCH] drm/mediatek: Fix device node reference leak in mtk_dp_dt_parse()

by Miaoqian Lin

The function mtk_dp_dt_parse() calls of_graph_get_endpoint_by_regs() to get the endpoint device node, but fails to call of_node_put() to release the reference when the function returns. This results in a device node reference leak. Fix this by adding the missing of_node_put() call before returning from the function. Found via static analysis and code review.

[PATCH] powerpc/kexec: Enable SMT before waking offline CPUs

by Nysal Jan K.A.

If SMT is disabled or a partial SMT state is enabled, when a new kernel image is loaded for kexec, on reboot the following warning is observed: kexec: Waking offline cpu 228. WARNING: CPU: 0 PID: 9062 at arch/powerpc/kexec/core_64.c:223 kexec_prepare_cpus+0x1b0/0x1bc [snip] NIP kexec_prepare_cpus+0x1b0/0x1bc LR kexec_prepare_cpus+0x1a0/0x1bc Call Trace: kexec_prepare_cpus+0x1a0/0x1bc (unreliable) default_machine_kexec+0x160/0x19c machine_kexec+0x80/0x88 kernel_kexec+0xd0/0x118 __do_sys_reboot+0x210/0x2c4 system_call_exception+0x124/0x320 system_call_vectored_common+0x15c/0x2ec This occurs as add_cpu() fails due to cpu_bootable() returning false for CPUs that fail the cpu_smt_thread_allowed() check or non primary threads if SMT is disabled. Fix the issue by enabling SMT and resetting the number of SMT threads to the number of threads per core, before attempting to wake up all present CPUs.

[PATCH v2] codetag: debug: handle existing CODETAG_EMPTY in mark_objexts_empty for slabobj_ext

by Hao Ge

From: Hao Ge <gehao(a)kylinos.cn> When alloc_slab_obj_exts() fails and then later succeeds in allocating a slab extension vector, it calls handle_failed_objexts_alloc() to mark all objects in the vector as empty. As a result all objects in this slab (slabA) will have their extensions set to CODETAG_EMPTY. Later on if this slabA is used to allocate a slabobj_ext vector for another slab (slabB), we end up with the slabB->obj_exts pointing to a slabobj_ext vector that itself has a non-NULL slabobj_ext equal to CODETAG_EMPTY. When slabB gets freed, free_slab_obj_exts() is called to free slabB->obj_exts vector. free_slab_obj_exts() calls mark_objexts_empty(slabB->obj_exts) which will generate a warning because it expects slabobj_ext vectors to have a NULL obj_ext, not CODETAG_EMPTY. Modify mark_objexts_empty() to skip the warning and setting the obj_ext value if it's already set to CODETAG_EMPTY.

+ codetag-debug-handle-existing-codetag_empty-in-mark_objexts_empty-for-slabobj_ext.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: codetag: debug: handle existing CODETAG_EMPTY in mark_objexts_empty for slabobj_ext has been added to the -mm mm-hotfixes-unstable branch. Its filename is codetag-debug-handle-existing-codetag_empty-in-mark_objexts_empty-for-slabobj_ext.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Hao Ge <gehao(a)kylinos.cn> Subject: codetag: debug: handle existing CODETAG_EMPTY in mark_objexts_empty for slabobj_ext Date: Wed, 29 Oct 2025 09:43:17 +0800 When alloc_slab_obj_exts() fails and then later succeeds in allocating a slab extension vector, it calls handle_failed_objexts_alloc() to mark all objects in the vector as empty. As a result all objects in this slab (slabA) will have their extensions set to CODETAG_EMPTY. Later on if this slabA is used to allocate a slabobj_ext vector for another slab (slabB), we end up with the slabB->obj_exts pointing to a slabobj_ext vector that itself has a non-NULL slabobj_ext equal to CODETAG_EMPTY. When slabB gets freed, free_slab_obj_exts() is called to free slabB->obj_exts vector. free_slab_obj_exts() calls mark_objexts_empty(slabB->obj_exts) which will generate a warning because it expects slabobj_ext vectors to have a NULL obj_ext, not CODETAG_EMPTY. Modify mark_objexts_empty() to skip the warning and setting the obj_ext value if it's already set to CODETAG_EMPTY. To quickly detect this WARN, I modified the code from:WARN_ON(slab_exts[offs].ref.ct) to WARN_ON(slab_exts[offs].ref.ct == 1); We then obtained this message: [21630.898561] ------------[ cut here ]------------ [21630.898596] kernel BUG at mm/slub.c:2050!
