git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "The most significant set of changes is the per netns RTNL. The new behavior is disabled by default, regression risk should be contained. Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its default value from PTP_1588_CLOCK_KVM, as the first is intended to be a more reliable replacement for the latter. Core: - Started a very large, in-progress, effort to make the RTNL lock scope per network-namespace, thus reducing the lock contention significantly in the containerized use-case, comprising: - RCU-ified some relevant slices of the FIB control path - introduce basic per netns locking helpers - namespacified the IPv4 address hash table - remove rtnl_register{,_module}() in favour of rtnl_register_many() - refactor rtnl_{new,del,set}link() moving as much validation as possible out of RTNL lock - convert all phonet doit() and dumpit() handlers to RCU - convert IPv4 addresses manipulation to per-netns RTNL - convert virtual interface creation to per-netns RTNL the per-netns lock infrastructure is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim. - Introduce NAPI suspension, to efficiently switching between busy polling (NAPI processing suspended) and normal processing. - Migrate the IPv4 routing input, output and control path from direct ToS usage to DSCP macros. This is a work in progress to make ECN handling consistent and reliable. - Add drop reasons support to the IPv4 rotue input path, allowing better introspection in case of packets drop. - Make FIB seqnum lockless, dropping RTNL protection for read access. - Make inet{,v6} addresses hashing less predicable. - Allow providing timestamp OPT_ID via cmsg, to correlate TX packets and timestamps Things we sprinkled into general kernel code: - Add small file operations for debugfs, to reduce the struct ops size. - Refactoring and optimization for the implementation of page_frag API, This is a preparatory work to consolidate the page_frag implementation. Netfilter: - Optimize set element transactions to reduce memory consumption - Extended netlink error reporting for attribute parser failure. - Make legacy xtables configs user selectable, giving users the option to configure iptables without enabling any other config. - Address a lot of false-positive RCU issues, pointed by recent CI improvements. BPF: - Put xsk sockets on a struct diet and add various cleanups. Overall, this helps to bump performance by 12% for some workloads. - Extend BPF selftests to increase coverage of XDP features in combination with BPF cpumap. - Optimize and homogenize bpf_csum_diff helper for all archs and also add a batch of new BPF selftests for it. - Extend netkit with an option to delegate skb->{mark,priority} scrubbing to its BPF program. - Make the bpf_get_netns_cookie() helper available also to tc(x) BPF programs. Protocols: - Introduces 4-tuple hash for connected udp sockets, speeding-up significantly connected sockets lookup. - Add a fastpath for some TCP timers that usually expires after close, the socket lock contention. - Add inbound and outbound xfrm state caches to speed up state lookups. - Avoid sending MPTCP advertisements on stale subflows, reducing risks on loosing them. - Make neighbours table flushing more scalable, maintaining per device neigh lists. Driver API: - Introduce a unified interface to configure transmission H/W shaping, and expose it to user-space via generic-netlink. - Add support for per-NAPI config via netlink. This makes napi configuration persistent across queues removal and re-creation. Requires driver updates, currently supported drivers are: nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice. - Add ethtool support for writing SFP / PHY firmware blocks. - Track RSS context allocation from ethtool core. - Implement support for mirroring to DSA CPU port, via TC mirror offload. - Consolidate FDB updates notification, to avoid duplicates on device-specific entries. - Expose DPLL clock quality level to the user-space. - Support master-slave PHY config via device tree. Tests and tooling: - forwarding: introduce deferred commands, to simplify the cleanup phase Drivers: - Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic, Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the IRQs and queues to NAPI IDs, allowing busy polling and better introspection. - Ethernet high-speed NICs: - nVidia/Mellanox: - mlx5: - a large refactor to implement support for cross E-Switch scheduling - refactor H/W conter management to let it scale better - H/W GRO cleanups - Intel (100G, ice):: - add support for ethtool reset - implement support for per TX queue H/W shaping - AMD/Solarflare: - implement per device queue stats support - Broadcom (bnxt): - improve wildcard l4proto on IPv4/IPv6 ntuple rules - Marvell Octeon: - Add representor support for each Resource Virtualization Unit (RVU) device. - Hisilicon: - add support for the BMC Gigabit Ethernet - IBM (EMAC): - driver cleanup and modernization - Cisco (VIC): - raise the queues number limit to 256 - Ethernet virtual: - Google vNIC: - implement page pool support - macsec: - inherit lower device's features and TSO limits when offloading - virtio_net: - enable premapped mode by default - support for XDP socket(AF_XDP) zerocopy TX - wireguard: - set the TSO max size to be GSO_MAX_SIZE, to aggregate larger packets. - Ethernet NICs embedded and virtual: - Broadcom ASP: - enable software timestamping - Freescale: - add enetc4 PF driver - MediaTek: Airoha SoC: - implement BQL support - RealTek r8169: - enable TSO by default on r8168/r8125 - implement extended ethtool stats - Renesas AVB: - enable TX checksum offload - Synopsys (stmmac): - support header splitting for vlan tagged packets - move common code for DWMAC4 and DWXGMAC into a separate FPE module. - add dwmac driver support for T-HEAD TH1520 SoC - Synopsys (xpcs): - driver refactor and cleanup - TI: - icssg_prueth: add VLAN offload support - Xilinx emaclite: - add clock support - Ethernet switches: - Microchip: - implement support for the lan969x Ethernet switch family - add LAN9646 switch support to KSZ DSA driver - Ethernet PHYs: - Marvel: 88q2x: enable auto negotiation - Microchip: add support for LAN865X Rev B1 and LAN867X Rev C1/C2 - PTP: - Add support for the Amazon virtual clock device - Add PtP driver for s390 clocks - WiFi: - mac80211 - EHT 1024 aggregation size for transmissions - new operation to indicate that a new interface is to be added - support radio separation of multi-band devices - move wireless extension spy implementation to libiw - Broadcom: - brcmfmac: optional LPO clock support - Microchip: - add support for Atmel WILC3000 - Qualcomm (ath12k): - firmware coredump collection support - add debugfs support for a multitude of statistics - Qualcomm (ath5k): - Arcadyan ARV45XX AR2417 & Gigaset SX76[23] AR241[34]A support - Realtek: - rtw88: 8821au and 8812au USB adapters support - rtw89: add thermal protection - rtw89: fine tune BT-coexsitence to improve user experience - rtw89: firmware secure boot for WiFi 6 chip - Bluetooth - add Qualcomm WCN785x support for ids Foxconn 0xe0fc/0xe0f3 and 0x13d3:0x3623 - add Realtek RTL8852BE support for id Foxconn 0xe123 - add MediaTek MT7920 support for wireless module ids - btintel_pcie: add handshake between driver and firmware - btintel_pcie: add recovery mechanism - btnxpuart: add GPIO support to power save feature" * tag 'net-next-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1475 commits) mm: page_frag: fix a compile error when kernel is not compiled Documentation: tipc: fix formatting issue in tipc.rst selftests: nic_performance: Add selftest for performance of NIC driver selftests: nic_link_layer: Add selftest case for speed and duplex states selftests: nic_link_layer: Add link layer selftest for NIC driver bnxt_en: Add FW trace coredump segments to the coredump bnxt_en: Add a new ethtool -W dump flag bnxt_en: Add 2 parameters to bnxt_fill_coredump_seg_hdr() bnxt_en: Add functions to copy host context memory bnxt_en: Do not free FW log context memory bnxt_en: Manage the FW trace context memory bnxt_en: Allocate backing store memory for FW trace logs bnxt_en: Add a 'force' parameter to bnxt_free_ctx_mem() bnxt_en: Refactor bnxt_free_ctx_mem() bnxt_en: Add mem_valid bit to struct bnxt_ctx_mem_type bnxt_en: Update firmware interface spec to 1.10.3.85 selftests/bpf: Add some tests with sockmap SK_PASS bpf: fix recursive lock when verdict program return SK_PASS wireguard: device: support big tcp GSO wireguard: selftests: load nf_conntrack if not present ...

2024-10-04net: add IFLA_MAX_PACING_OFFLOAD_HORIZON device attributeEric Dumazet1-0/+1
Some network devices have the ability to offload EDT (Earliest Departure Time) which is the model used for TCP pacing and FQ packet scheduler. Some of them implement the timing wheel mechanism described in https://saeed.github.io/files/carousel-sigcomm17.pdf with an associated 'timing wheel horizon'. This patch adds dev->max_pacing_offload_horizon expressing this timing wheel horizon in nsec units. This is a read-only attribute. Unless a driver sets it, dev->max_pacing_offload_horizon is zero. v2: addressed Jakub feedback ( https://lore.kernel.org/netdev/20240930152304.472767-2-edumazet@google.com/T/#mf6294d714c41cc459962154cc2580ce3c9693663 ) v3: added yaml doc (also per Jakub feedback) Signed-off-by: Eric Dumazet <edumazet@google.com> Reviewed-by: Willem de Bruijn <willemb@google.com> Link: https://patch.msgid.link/20241003121219.2396589-2-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull random number generator updates from Jason Donenfeld: "Originally I'd planned on sending each of the vDSO getrandom() architecture ports to their respective arch trees. But as we started to work on this, we found lots of interesting issues in the shared code and infrastructure, the fixes for which the various archs needed to base their work. So in the end, this turned into a nice collaborative effort fixing up issues and porting to 5 new architectures -- arm64, powerpc64, powerpc32, s390x, and loongarch64 -- with everybody pitching in and commenting on each other's code. It was a fun development cycle. This contains: - Numerous fixups to the vDSO selftest infrastructure, getting it running successfully on more platforms, and fixing bugs in it. - Additions to the vDSO getrandom & chacha selftests. Basically every time manual review unearthed a bug in a revision of an arch patch, or an ambiguity, the tests were augmented. By the time the last arch was submitted for review, s390x, v1 of the series was essentially fine right out of the gate. - Fixes to the the generic C implementation of vDSO getrandom, to build and run successfully on all archs, decoupling it from assumptions we had (unintentionally) made on x86_64 that didn't carry through to the other architectures. - Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by Huacai Chen. - Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked by Will Deacon. - Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit varieties, from Christophe Leroy and acked by Michael Ellerman. - Port of vDSO getrandom to S390X from Heiko Carstens, the arch maintainer. While it'd be natural for there to be things to fix up over the course of the development cycle, these patches got a decent amount of review from a fairly diverse crew of folks on the mailing lists, and, for the most part, they've been cooking in linux-next, which has been helpful for ironing out build issues. In terms of architectures, I think that mostly takes care of the important 64-bit archs with hardware still being produced and running production loads in settings where vDSO getrandom is likely to help. Arguably there's still RISC-V left, and we'll see for 6.13 whether they find it useful and submit a port" * tag 'random-6.12-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: (47 commits) selftests: vDSO: check cpu caps before running chacha test s390/vdso: Wire up getrandom() vdso implementation s390/vdso: Move vdso symbol handling to separate header file s390/vdso: Allow alternatives in vdso code s390/module: Provide find_section() helper s390/facility: Let test_facility() generate static branch if possible s390/alternatives: Remove ALT_FACILITY_EARLY s390/facility: Disable compile time optimization for decompressor code selftests: vDSO: fix vdso_config for s390 selftests: vDSO: fix ELF hash table entry size for s390x powerpc/vdso: Wire up getrandom() vDSO implementation on VDSO64 powerpc/vdso: Wire up getrandom() vDSO implementation on VDSO32 powerpc/vdso: Refactor CFLAGS for CVDSO build powerpc/vdso32: Add crtsavres mm: Define VM_DROPPABLE for powerpc/32 powerpc/vdso: Fix VDSO data access when running in a non-root time namespace selftests: vDSO: don't include generated headers for chacha test arm64: vDSO: Wire up getrandom() vDSO implementation arm64: alternative: make alternative_has_cap_likely() VDSO compatible selftests: vDSO: also test counter in vdso_test_chacha ...

2024-09-16selftests: vDSO: check cpu caps before running chacha testJason A. Donenfeld1-0/+10
Some archs -- arm64 and s390x -- implemented chacha using instructions that are available most places, but aren't always available. The kernel handles this just fine, but the selftest does not. Check the hwcaps before running, and skip the test if the cpu doesn't support it. As well, on s390x, always emit the fallback instructions of an alternative block, to ensure maximum compatibility.

It's not correct to use $(top_srcdir) for generated header files, for builds that are done out of tree via O=, and $(objtree) isn't valid in the selftests context. Instead, just obviate the need for these generated header files by defining empty stubs in tools/include, which is the same thing that's done for rwlock.h.

2024-09-13arm64: vDSO: Wire up getrandom() vDSO implementationAdhemerval Zanella1-0/+4
Hook up the generic vDSO implementation to the aarch64 vDSO data page. The _vdso_rng_data required data is placed within the _vdso_data vvar page, by using a offset larger than the vdso_data. The vDSO function requires a ChaCha20 implementation that does not write to the stack, and that can do an entire ChaCha20 permutation. The one provided uses NEON on the permute operation, with a fallback to the syscall for chips that do not support AdvSIMD. This also passes the vdso_test_chacha test along with vdso_test_getrandom. The vdso_test_getrandom bench-single result on Neoverse-N1 shows: vdso: 25000000 times in 0.783884250 seconds libc: 25000000 times in 8.780275399 seconds syscall: 25000000 times in 8.786581518 seconds A small fixup to arch/arm64/include/asm/mman.h was required to avoid pulling kernel code into the vDSO, similar to what's already done in arch/arm64/include/asm/rwonce.h.
