2025-07-03netfilter: conntrack: remove DCCP protocol supportPablo Neira Ayuso
The DCCP socket family has now been removed from this tree, see: 8bb3212be4b4 ("Merge branch 'net-retire-dccp-socket'") Remove connection tracking and NAT support for this protocol, this should not pose a problem because no DCCP traffic is expected to be seen on the wire. As for the code for matching on dccp header for iptables and nftables, mark it as deprecated and keep it in place. Ruleset restoration is an atomic operation. Without dccp matching support, an astray match on dccp could break this operation leaving your computer with no policy in place, so let's follow a more conservative approach for matches. Add CONFIG_NFT_EXTHDR_DCCP which is set to 'n' by default to deprecate dccp extension support. Similarly, label CONFIG_NETFILTER_XT_MATCH_DCCP as deprecated too and also set it to 'n' by default. Code to match on DCCP protocol from ebtables also remains in place, this is just a few checks on IPPROTO_DCCP from _check() path which is exercised when ruleset is loaded. There is another use of IPPROTO_DCCP from the _check() path in the iptables multiport match. Another check for IPPROTO_DCCP from the packet in the reject target is also removed. So let's schedule removal of the dccp matching for a second stage, this should not interfer with the dccp retirement since this is only matching on the dccp header. Cc: "David S.

2025-07-03MIPS: Don't crash in stack_top() for tasks without ABI or vDSOThomas Weißschuh
Not all tasks have an ABI associated or vDSO mapped, for example kthreads never do. If such a task ever ends up calling stack_top(), it will derefence the NULL ABI pointer and crash. This can for example happen when using kunit: mips_stack_top+0x28/0xc0 arch_pick_mmap_layout+0x190/0x220 kunit_vm_mmap_init+0xf8/0x138 __kunit_add_resource+0x40/0xa8 kunit_vm_mmap+0x88/0xd8 usercopy_test_init+0xb8/0x240 kunit_try_run_case+0x5c/0x1a8 kunit_generic_run_threadfn_adapter+0x28/0x50 kthread+0x118/0x240 ret_from_kernel_thread+0x14/0x1c Only dereference the ABI point if it is set. The GIC page is also included as it is specific to the vDSO. Also move the randomization adjustment into the same conditional.

2025-07-02fs: introduce file_getattr and file_setattr syscallsAndrey Albershteyn
Introduce file_getattr() and file_setattr() syscalls to manipulate inode extended attributes. The syscalls takes pair of file descriptor and pathname. Then it operates on inode opened accroding to openat() semantics. The struct file_attr is passed to obtain/change extended attributes. This is an alternative to FS_IOC_FSSETXATTR ioctl with a difference that file don't need to be open as we can reference it with a path instead of fd. By having this we can manipulated inode extended attributes not only on regular files but also on special ones. This is not possible with FS_IOC_FSSETXATTR ioctl as with special files we can not call ioctl() directly on the filesystem inode using fd. This patch adds two new syscalls which allows userspace to get/set extended inode attributes on special files by using parent directory and a path - *at() like syscall.

Move the contents of arch/mips/lib/crypto/ into lib/crypto/mips/. The new code organization makes a lot more sense for how this code actually works and is developed. In particular, it makes it possible to build each algorithm as a single module, with better inlining and dead code elimination. For a more detailed explanation, see the patchset which did this for the CRC library code: https://lore.kernel.org/r/20250607200454.73587-1-ebiggers@kernel.org/. Also see the patchset which did this for SHA-512: https://lore.kernel.org/linux-crypto/20250616014019.415791-1-ebiggers@kernel.org/ This is just a preparatory commit, which does the move to get the files into their new location but keeps them building the same way as before. Later commits will make the actual improvements to the way the arch-optimized code is integrated for each algorithm. Add a gitignore entry for the removed directory arch/mips/lib/crypto/ so that people don't accidentally commit leftover generated files.

2025-06-30lib/crypto: mips/sha512: Migrate optimized SHA-512 code to libraryEric Biggers
Instead of exposing the mips-optimized SHA-512 code via mips-specific crypto_shash algorithms, instead just implement the sha512_blocks() library function. This is much simpler, it makes the SHA-512 (and SHA-384) library functions be mips-optimized, and it fixes the longstanding issue where the mips-optimized SHA-512 code was disabled by default. SHA-512 still remains available through crypto_shash, but individual architectures no longer need to handle it.

This fixes swap/swapoff problems on Alpha due pte_swp_exclusive not returning correct values when _PAGE_SWP_EXCLUSIVE bit resides in upper 32-bits of PTE (like on alpha).

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - "Add folio_mk_pte()" from Matthew Wilcox simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction. In a simple test case, the reduction of a guest VM's memory consumption was dramatic. - "Minor cleanups and improvements to swap freeing code" from Kemeng Shi provides some code cleaups and a small efficiency improvement to this part of our swap handling code. - "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin adds the ability for a ptracer to modify syscalls arguments. At this time we can alter only "system call information that are used by strace system call tampering, namely, syscall number, syscall arguments, and syscall return value. This series should have been incorporated into mm.git's "non-MM" branch, but I goofed. - "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl against /proc/pid/pagemap. This permits CRIU to more efficiently get at the info about guard regions. - "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan implements that fix. No runtime effect is expected because validate_page_before_insert() happens to fix up this error. - "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David Hildenbrand basically brings uprobe text poking into the current decade. Remove a bunch of hand-rolled implementation in favor of using more current facilities. - "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman Khandual provides enhancements and generalizations to the pte dumping code. This might be needed when 128-bit Page Table Descriptors are enabled for ARM. - "Always call constructor for kernel page tables" from Kevin Brodsky ensures that the ctor/dtor is always called for kernel pgtables, as it already is for user pgtables. This permits the addition of more functionality such as "insert hooks to protect page tables". This change does result in various architectures performing unnecesary work, but this is fixed up where it is anticipated to occur. - "Rust support for mm_struct, vm_area_struct, and mmap" from Alice Ryhl adds plumbing to permit Rust access to core MM structures. - "fix incorrectly disallowed anonymous VMA merges" from Lorenzo Stoakes takes advantage of some VMA merging opportunities which we've been missing for 15 years. - "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from SeongJae Park optimizes process_madvise()'s TLB flushing. Instead of flushing each address range in the provided iovec, we batch the flushing across all the iovec entries. The syscall's cost was approximately halved with a microbenchmark which was designed to load this particular operation. - "Track node vacancy to reduce worst case allocation counts" from Sidhartha Kumar makes the maple tree smarter about its node preallocation. stress-ng mmap performance increased by single-digit percentages and the amount of unnecessarily preallocated memory was dramaticelly reduced. - "mm/gup: Minor fix, cleanup and improvements" from Baoquan He removes a few unnecessary things which Baoquan noted when reading the code. - ""Enhance sysfs handling for memory hotplug in weighted interleave" from Rakie Kim "enhances the weighted interleave policy in the memory management subsystem by improving sysfs handling, fixing memory leaks, and introducing dynamic sysfs updates for memory hotplug support". Fixes things on error paths which we are unlikely to hit. - "mm/damon: auto-tune DAMOS for NUMA setups including tiered memory" from SeongJae Park introduces new DAMOS quota goal metrics which eliminate the manual tuning which is required when utilizing DAMON for memory tiering. - "mm/vmalloc.c: code cleanup and improvements" from Baoquan He provides cleanups and small efficiency improvements which Baoquan found via code inspection. - "vmscan: enforce mems_effective during demotion" from Gregory Price changes reclaim to respect cpuset.mems_effective during demotion when possible. because presently, reclaim explicitly ignores cpuset.mems_effective when demoting, which may cause the cpuset settings to violated. This is useful for isolating workloads on a multi-tenant system from certain classes of memory more consistently. - "Clean up split_huge_pmd_locked() and remove unnecessary folio pointers" from Gavin Guo provides minor cleanups and efficiency gains in in the huge page splitting and migrating code. - "Use kmem_cache for memcg alloc" from Huan Yang creates a slab cache for `struct mem_cgroup', yielding improved memory utilization. - "add max arg to swappiness in memory.reclaim and lru_gen" from Zhongkun He adds a new "max" argument to the "swappiness=" argument for memory.reclaim MGLRU's lru_gen. This directs proactive reclaim to reclaim from only anon folios rather than file-backed folios. - "kexec: introduce Kexec HandOver (KHO)" from Mike Rapoport is the first step on the path to permitting the kernel to maintain existing VMs while replacing the host kernel via file-based kexec. At this time only memblock's reserve_mem is preserved. - "mm: Introduce for_each_valid_pfn()" from David Woodhouse provides and uses a smarter way of looping over a pfn range. By skipping ranges of invalid pfns. - "sched/numa: Skip VMA scanning on memory pinned to one NUMA node via cpuset.mems" from Libo Chen removes a lot of pointless VMA scanning when a task is pinned a single NUMA mode. Dramatic performance benefits were seen in some real world cases. - "JFS: Implement migrate_folio for jfs_metapage_aops" from Shivank Garg addresses a warning which occurs during memory compaction when using JFS. - "move all VMA allocation, freeing and duplication logic to mm" from Lorenzo Stoakes moves some VMA code from kernel/fork.c into the more appropriate mm/vma.c. - "mm, swap: clean up swap cache mapping helper" from Kairui Song provides code consolidation and cleanups related to the folio_index() function. - "mm/gup: Cleanup memfd_pin_folios()" from Vishal Moola does that. - "memcg: Fix test_memcg_min/low test failures" from Waiman Long addresses some bogus failures which are being reported by the test_memcontrol selftest. - "eliminate mmap() retry merge, add .mmap_prepare hook" from Lorenzo Stoakes commences the deprecation of file_operations.mmap() in favor of the new file_operations.mmap_prepare(). The latter is more restrictive and prevents drivers from messing with things in ways which, amongst other problems, may defeat VMA merging. - "memcg: decouple memcg and objcg stocks"" from Shakeel Butt decouples the per-cpu memcg charge cache from the objcg's one. This is a step along the way to making memcg and objcg charging NMI-safe, which is a BPF requirement. - "mm/damon: minor fixups and improvements for code, tests, and documents" from SeongJae Park is yet another batch of miscellaneous DAMON changes. Fix and improve minor problems in code, tests and documents. - "memcg: make memcg stats irq safe" from Shakeel Butt converts memcg stats to be irq safe. Another step along the way to making memcg charging and stats updates NMI-safe, a BPF requirement. - "Let unmap_hugepage_range() and several related functions take folio instead of page" from Fan Ni provides folio conversions in the hugetlb code. * tag 'mm-stable-2025-05-31-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (285 commits) mm: pcp: increase pcp->free_count threshold to trigger free_high mm/hugetlb: convert use of struct page to folio in __unmap_hugepage_range() mm/hugetlb: refactor __unmap_hugepage_range() to take folio instead of page mm/hugetlb: refactor unmap_hugepage_range() to take folio instead of page mm/hugetlb: pass folio instead of page to unmap_ref_private() memcg: objcg stock trylock without irq disabling memcg: no stock lock for cpu hot-unplug memcg: make __mod_memcg_lruvec_state re-entrant safe against irqs memcg: make count_memcg_events re-entrant safe against irqs memcg: make mod_memcg_state re-entrant safe against irqs memcg: move preempt disable to callers of memcg_rstat_updated memcg: memcg_rstat_updated re-entrant safe against irqs mm: khugepaged: decouple SHMEM and file folios' collapse selftests/eventfd: correct test name and improve messages alloc_tag: check mem_profiling_support in alloc_tag_init Docs/damon: update titles and brief introductions to explain DAMOS selftests/damon/_damon_sysfs: read tried regions directories in order mm/damon/tests/core-kunit: add a test for damos_set_filters_default_reject() mm/damon/paddr: remove unused variable, folio_list, in damon_pa_stat() mm/damon/sysfs-schemes: fix wrong comment on damons_sysfs_quota_goal_metric_strs ...

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "Core: - Implement the Device Memory TCP transmit path, allowing zero-copy data transmission on top of TCP from e.g. GPU memory to the wire. - Move all the IPv6 routing tables management outside the RTNL scope, under its own lock and RCU. The route control path is now 3x times faster. - Convert queue related netlink ops to instance lock, reducing again the scope of the RTNL lock. This improves the control plane scalability. - Refactor the software crc32c implementation, removing unneeded abstraction layers and improving significantly the related micro-benchmarks. - Optimize the GRO engine for UDP-tunneled traffic, for a 10% performance improvement in related stream tests. - Cover more per-CPU storage with local nested BH locking; this is a prep work to remove the current per-CPU lock in local_bh_disable() on PREMPT_RT. - Introduce and use nlmsg_payload helper, combining buffer bounds verification with accessing payload carried by netlink messages. Netfilter: - Rewrite the procfs conntrack table implementation, improving considerably the dump performance. A lot of user-space tools still use this interface. - Implement support for wildcard netdevice in netdev basechain and flowtables. - Integrate conntrack information into nft trace infrastructure. - Export set count and backend name to userspace, for better introspection. BPF: - BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops programs and can be controlled in similar way to traditional qdiscs using the "tc qdisc" command. - Refactor the UDP socket iterator, addressing long standing issues WRT duplicate hits or missed sockets. Protocols: - Improve TCP receive buffer auto-tuning and increase the default upper bound for the receive buffer; overall this improves the single flow maximum thoughput on 200Gbs link by over 60%. - Add AFS GSSAPI security class to AF_RXRPC; it provides transport security for connections to the AFS fileserver and VL server. - Improve TCP multipath routing, so that the sources address always matches the nexthop device. - Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS, and thus preventing DoS caused by passing around problematic FDs. - Retire DCCP socket. DCCP only receives updates for bugs, and major distros disable it by default. Its removal allows for better organisation of TCP fields to reduce the number of cache lines hit in the fast path. - Extend TCP drop-reason support to cover PAWS checks. Driver API: - Reorganize PTP ioctl flag support to require an explicit opt-in for the drivers, avoiding the problem of drivers not rejecting new unsupported flags. - Converted several device drivers to timestamping APIs. - Introduce per-PHY ethtool dump helpers, improving the support for dump operations targeting PHYs. Tests and tooling: - Add support for classic netlink in user space C codegen, so that ynl-c can now read, create and modify links, routes addresses and qdisc layer configuration. - Add ynl sub-types for binary attributes, allowing ynl-c to output known struct instead of raw binary data, clarifying the classic netlink output. - Extend MPTCP selftests to improve the code-coverage. - Add tests for XDP tail adjustment in AF_XDP. New hardware / drivers: - OpenVPN virtual driver: offload OpenVPN data channels processing to the kernel-space, increasing the data transfer throughput WRT the user-space implementation. - Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC. - Broadcom asp-v3.0 ethernet driver. - AMD Renoir ethernet device. - ReakTek MT9888 2.5G ethernet PHY driver. - Aeonsemi 10G C45 PHYs driver.
