git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Complete rework of garbage collection of AF_UNIX sockets. AF_UNIX is prone to forming reference count cycles due to fd passing functionality. New method based on Tarjan's Strongly Connected Components algorithm should be both faster and remove a lot of workarounds we accumulated over the years. - Add TCP fraglist GRO support, allowing chaining multiple TCP packets and forwarding them together. Useful for small switches / routers which lack basic checksum offload in some scenarios (e.g. PPPoE). - Support using SMP threads for handling packet backlog i.e. packet processing from software interfaces and old drivers which don't use NAPI. This helps move the processing out of the softirq jumble. - Continue work of converting from rtnl lock to RCU protection. Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link information available via rtnetlink. - Small optimizations from Eric to UDP wake up handling, memory accounting, RPS/RFS implementation, TCP packet sizing etc. - Allow direct page recycling in the bulk API used by XDP, for +2% PPS. - Support peek with an offset on TCP sockets. - Add MPTCP APIs for querying last time packets were received/sent/acked and whether MPTCP "upgrade" succeeded on a TCP socket. - Add intra-node communication shortcut to improve SMC performance. - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver. - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver. - Add reset reasons for tracing what caused a TCP reset to be sent. - Introduce direction attribute for xfrm (IPSec) states. State can be used either for input or output packet processing. Things we sprinkled into general kernel code: - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS(). This required touch-ups and renaming of a few existing users. - Add Endian-dependent __counted_by_{le,be} annotations. - Make building selftests "quieter" by printing summaries like "CC object.o" rather than full commands with all the arguments. Netfilter: - Use GFP_KERNEL to clone elements, to deal better with OOM situations and avoid failures in the .commit step. BPF: - Add eBPF JIT for ARCv2 CPUs. - Support attaching kprobe BPF programs through kprobe_multi link in a session mode, meaning, a BPF program is attached to both function entry and return, the entry program can decide if the return program gets executed and the entry program can share u64 cookie value with return program. "Session mode" is a common use-case for tetragon and bpftrace. - Add the ability to specify and retrieve BPF cookie for raw tracepoint programs in order to ease migration from classic to raw tracepoints. - Add an internal-only BPF per-CPU instruction for resolving per-CPU memory addresses and implement support in x86, ARM64 and RISC-V JITs. This allows inlining functions which need to access per-CPU state. - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various atomics in bpf_arena which can be JITed as a single x86 instruction. Support BPF arena on ARM64. - Add a new bpf_wq API for deferring events and refactor process-context bpf_timer code to keep common code where possible. - Harden the BPF verifier's and/or/xor value tracking. - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs. - Support bpf_tail_call_static() helper for BPF programs with GCC 13. - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF program to have code sections where preemption is disabled. Driver API: - Skip software TC processing completely if all installed rules are marked as HW-only, instead of checking the HW-only flag rule by rule. - Add support for configuring PoE (Power over Ethernet), similar to the already existing support for PoDL (Power over Data Line) config. - Initial bits of a queue control API, for now allowing a single queue to be reset without disturbing packet flow to other queues. - Common (ethtool) statistics for hardware timestamping. Tests and tooling: - Remove the need to create a config file to run the net forwarding tests so that a naive "make run_tests" can exercise them. - Define a method of writing tests which require an external endpoint to communicate with (to send/receive data towards the test machine). Add a few such tests. - Create a shared code library for writing Python tests. Expose the YAML Netlink library from tools/ to the tests for easy Netlink access. - Move netfilter tests under net/, extend them, separate performance tests from correctness tests, and iron out issues found by running them "on every commit". - Refactor BPF selftests to use common network helpers. - Further work filling in YAML definitions of Netlink messages for: nftables, team driver, bonding interfaces, vlan interfaces, VF info, TC u32 mark, TC police action. - Teach Python YAML Netlink to decode attribute policies. - Extend the definition of the "indexed array" construct in the specs to cover arrays of scalars rather than just nests. - Add hyperlinks between definitions in generated Netlink docs. Drivers: - Make sure unsupported flower control flags are rejected by drivers, and make more drivers report errors directly to the application rather than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen). - Ethernet high-speed NICs: - Broadcom (bnxt): - support multiple RSS contexts and steering traffic to them - support XDP metadata - make page pool allocations more NUMA aware - Intel (100G, ice, idpf): - extract datapath code common among Intel drivers into a library - use fewer resources in switchdev by sharing queues with the PF - add PFCP filter support - add Ethernet filter support - use a spinlock instead of HW lock in PTP clock ops - support 5 layer Tx scheduler topology - nVidia/Mellanox: - 800G link modes and 100G SerDes speeds - per-queue IRQ coalescing configuration - Marvell Octeon: - support offloading TC packet mark action - Ethernet NICs consumer, embedded and virtual: - stop lying about skb->truesize in USB Ethernet drivers, it messes up TCP memory calculations - Google cloud vNIC: - support changing ring size via ethtool - support ring reset using the queue control API - VirtIO net: - expose flow hash from RSS to XDP - per-queue statistics - add selftests - Synopsys (stmmac): - support controllers which require an RX clock signal from the MII bus to perform their hardware initialization - TI: - icssg_prueth: support ICSSG-based Ethernet on AM65x SR1.0 devices - icssg_prueth: add SW TX / RX Coalescing based on hrtimers - cpsw: minimal XDP support - Renesas (ravb): - support describing the MDIO bus - Realtek (r8169): - add support for RTL8168M - Microchip Sparx5: - matchall and flower actions mirred and redirect - Ethernet switches: - nVidia/Mellanox: - improve events processing performance - Marvell: - add support for MV88E6250 family internal PHYs - Microchip: - add DCB and DSCP mapping support for KSZ switches - vsc73xx: convert to PHYLINK - Realtek: - rtl8226b/rtl8221b: add C45 instances and SerDes switching - Many driver changes related to PHYLIB and PHYLINK deprecated API cleanup - Ethernet PHYs: - Add a new driver for Airoha EN8811H 2.5 Gigabit PHY. - micrel: lan8814: add support for PPS out and external timestamp trigger - WiFi: - Disable Wireless Extensions (WEXT) in all Wi-Fi 7 devices drivers.

2024-03-28net: remove gfp_mask from napi_alloc_skb()Jakub Kicinski
__napi_alloc_skb() is napi_alloc_skb() with the added flexibility of choosing gfp_mask. This is a NAPI function, so GFP_ATOMIC is implied. The only practical choice the caller has is whether to set __GFP_NOWARN. But that's a false choice, too, allocation failures in atomic context will happen, and printing warnings in logs, effectively for a packet drop, is both too much and very likely non-actionable. This leads me to a conclusion that most uses of napi_alloc_skb() are simply misguided, and should use __GFP_NOWARN in the first place. We also have a "standard" way of reporting allocation failures via the queue stat API (qstats::rx-alloc-fail). The direct motivation for this patch is that one of the drivers used at Meta calls napi_alloc_skb() (so prior to this patch without __GFP_NOWARN), and the resulting OOM warning is the top networking warning in our fleet.

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - Sumanth Korikkar has taught s390 to allocate hotplug-time page frames from hotplugged memory rather than only from main memory. Series "implement "memmap on memory" feature on s390". - More folio conversions from Matthew Wilcox in the series "Convert memcontrol charge moving to use folios" "mm: convert mm counter to take a folio" - Chengming Zhou has optimized zswap's rbtree locking, providing significant reductions in system time and modest but measurable reductions in overall runtimes. The series is "mm/zswap: optimize the scalability of zswap rb-tree". - Chengming Zhou has also provided the series "mm/zswap: optimize zswap lru list" which provides measurable runtime benefits in some swap-intensive situations. - And Chengming Zhou further optimizes zswap in the series "mm/zswap: optimize for dynamic zswap_pools". Measured improvements are modest. - zswap cleanups and simplifications from Yosry Ahmed in the series "mm: zswap: simplify zswap_swapoff()". - In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has contributed several DAX cleanups as well as adding a sysfs tunable to control the memmap_on_memory setting when the dax device is hotplugged as system memory. - Johannes Weiner has added the large series "mm: zswap: cleanups", which does that. - More DAMON work from SeongJae Park in the series "mm/damon: make DAMON debugfs interface deprecation unignorable" "selftests/damon: add more tests for core functionalities and corner cases" "Docs/mm/damon: misc readability improvements" "mm/damon: let DAMOS feeds and tame/auto-tune itself" - In the series "mm/mempolicy: weighted interleave mempolicy and sysfs extension" Rakie Kim has developed a new mempolicy interleaving policy wherein we allocate memory across nodes in a weighted fashion rather than uniformly. This is beneficial in heterogeneous memory environments appearing with CXL. - Christophe Leroy has contributed some cleanup and consolidation work against the ARM pagetable dumping code in the series "mm: ptdump: Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute". - Luis Chamberlain has added some additional xarray selftesting in the series "test_xarray: advanced API multi-index tests". - Muhammad Usama Anjum has reworked the selftest code to make its human-readable output conform to the TAP ("Test Anything Protocol") format. Amongst other things, this opens up the use of third-party tools to parse and process out selftesting results. - Ryan Roberts has added fork()-time PTE batching of THP ptes in the series "mm/memory: optimize fork() with PTE-mapped THP". Mainly targeted at arm64, this significantly speeds up fork() when the process has a large number of pte-mapped folios. - David Hildenbrand also gets in on the THP pte batching game in his series "mm/memory: optimize unmap/zap with PTE-mapped THP". It implements batching during munmap() and other pte teardown situations. The microbenchmark improvements are nice. - And in the series "Transparent Contiguous PTEs for User Mappings" Ryan Roberts further utilizes arm's pte's contiguous bit ("contpte mappings"). Kernel build times on arm64 improved nicely. Ryan's series "Address some contpte nits" provides some followup work. - In the series "mm/hugetlb: Restore the reservation" Breno Leitao has fixed an obscure hugetlb race which was causing unnecessary page faults. He has also added a reproducer under the selftest code. - In the series "selftests/mm: Output cleanups for the compaction test", Mark Brown did what the title claims. - Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring". - Even more zswap material from Nhat Pham. The series "fix and extend zswap kselftests" does as claimed. - In the series "Introduce cpu_dcache_is_aliasing() to fix DAX regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in our handling of DAX on archiecctures which have virtually aliasing data caches. The arm architecture is the main beneficiary. - Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic improvements in worst-case mmap_lock hold times during certain userfaultfd operations. - Some page_owner enhancements and maintenance work from Oscar Salvador in his series "page_owner: print stacks and their outstanding allocations" "page_owner: Fixup and cleanup" - Uladzislau Rezki has contributed some vmalloc scalability improvements in his series "Mitigate a vmap lock contention". It realizes a 12x improvement for a certain microbenchmark. - Some kexec/crash cleanup work from Baoquan He in the series "Split crash out from kexec and clean up related config items". - Some zsmalloc maintenance work from Chengming Zhou in the series "mm/zsmalloc: fix and optimize objects/page migration" "mm/zsmalloc: some cleanup for get/set_zspage_mapping()" - Zi Yan has taught the MM to perform compaction on folios larger than order=0. This a step along the path to implementaton of the merging of large anonymous folios. The series is named "Enable >0 order folio memory compaction". - Christoph Hellwig has done quite a lot of cleanup work in the pagecache writeback code in his series "convert write_cache_pages() to an iterator". - Some modest hugetlb cleanups and speedups in Vishal Moola's series "Handle hugetlb faults under the VMA lock". - Zi Yan has changed the page splitting code so we can split huge pages into sizes other than order-0 to better utilize large folios. The series is named "Split a folio to any lower order folios". - David Hildenbrand has contributed the series "mm: remove total_mapcount()", a cleanup. - Matthew Wilcox has sought to improve the performance of bulk memory freeing in his series "Rearrange batched folio freeing". - Gang Li's series "hugetlb: parallelize hugetlb page init on boot" provides large improvements in bootup times on large machines which are configured to use large numbers of hugetlb pages. - Matthew Wilcox's series "PageFlags cleanups" does that. - Qi Zheng's series "minor fixes and supplement for ptdesc" does that also. S390 is affected. - Cleanups to our pagemap utility functions from Peter Xu in his series "mm/treewide: Replace pXd_large() with pXd_leaf()". - Nico Pache has fixed a few things with our hugepage selftests in his series "selftests/mm: Improve Hugepage Test Handling in MM Selftests". - Also, of course, many singleton patches to many things.

2024-03-12sched/balancing: Rename load_balance() => sched_balance_rq()Ingo Molnar
Standardize scheduler load-balancing function names on the sched_balance_() prefix. Also load_balance() has become somewhat of a misnomer: historically it was the first and primary load-balancing function that was called, but with the introduction of sched domains, it's become a lower layer function that balances runqueues. Rename it to sched_balance_rq() accordingly.

2024-03-12sched/balancing: Rename scheduler_tick() => sched_tick()Ingo Molnar
- Standardize on prefixing scheduler-internal functions defined in <linux/sched.h> with sched_*() prefix. scheduler_tick() was the only function using the scheduler_ prefix. Harmonize it. - The other reason to rename it is the NOHZ scheduler tick handling functions are already named sched_tick_*(). Make the 'git grep sched_tick' more meaningful.

run_rebalance_domains() is a misnomer, as it doesn't only run rebalance_domains(), but since the introduction of the NOHZ code it also runs nohz_idle_balance(). Rename it to sched_balance_softirq(), reflecting its more generic purpose and that it's a softirq handler.
