Merge tag 'net-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking changes from Jakub Kicinski: "WiFi 7 and sendpage changes are the biggest pieces of work for this release. The latter will definitely require fixes but I think that we got it to a reasonable point.
Core:
- Rework the sendpage & splice implementations
Instead of feeding data into sockets page by page extend sendmsg handlers to support taking a reference on the data, controlled by a new flag called MSG_SPLICE_PAGES
Rework the handling of unexpected-end-of-file to invoke an additional callback instead of trying to predict what the right combination of MORE/NOTLAST flags is
Remove the MSG_SENDPAGE_NOTLAST flag completely
- Implement SCM_PIDFD, a new type of CMSG type analogous to SCM_CREDENTIALS, but it contains pidfd instead of plain pid
- Enable socket busy polling with CONFIG_RT
- Improve reliability and efficiency of reporting for ref_tracker
- Auto-generate a user space C library for various Netlink families
Protocols:
- Allow TCP to shrink the advertised window when necessary, prevent sk_rcvbuf auto-tuning from growing the window all the way up to tcp_rmem[2]
- Use per-VMA locking for "page-flipping" TCP receive zerocopy
- Prepare TCP for device-to-device data transfers, by making sure that payloads are always attached to skbs as page frags
- Make the backoff time for the first N TCP SYN retransmissions linear. Exponential backoff is unnecessarily conservative
- Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO)
- Avoid waking up applications using TLS sockets until we have a full record
- Allow using kernel memory for protocol ioctl callbacks, paving the way to issuing ioctls over io_uring
- Add nolocalbypass option to VxLAN, forcing packets to be fully encapsulated even if they are destined for a local IP address
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure in-kernel ECMP implementation (e.g. Open vSwitch) select the same link for all packets. Support L4 symmetric hashing in Open vSwitch
- PPPoE: make number of hash bits configurable
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client (ipconfig)
- Add layer 2 miss indication and filtering, allowing higher layers (e.g. ACL filters) to make forwarding decisions based on whether packet matched forwarding state in lower devices (bridge)
- Support matching on Connectivity Fault Management (CFM) packets
- Hide the "link becomes ready" IPv6 messages by demoting their printk level to debug
- HSR: don't enable promiscuous mode if device offloads the proto
- Support active scanning in IEEE 802.15.4
- Continue work on Multi-Link Operation for WiFi 7
BPF:
- Add precision propagation for subprogs and callbacks. This allows maintaining verification efficiency when subprograms are used, or in fact passing the verifier at all for complex programs, especially those using open-coded iterators
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF assumed the length is always equal to the amount of written data. But some protos allow passing a NULL buffer to discover what the output buffer *should* be, without writing anything
- Accept dynptr memory as memory arguments passed to helpers
- Add routing table ID to bpf_fib_lookup BPF helper
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark maps as read-only)
- Show target_{obj,btf}_id in tracing link fdinfo
- Addition of several new kfuncs (most of the names are self-explanatory): - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(), bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size() and bpf_dynptr_clone(). - bpf_task_under_cgroup() - bpf_sock_destroy() - force closing sockets - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter:
- Relax set/map validation checks in nf_tables. Allow checking presence of an entry in a map without using the value
- Increase ip_vs_conn_tab_bits range for 64BIT builds
- Allow updating size of a set
- Improve NAT tuple selection when connection is closing
Driver API:
- Integrate netdev with LED subsystem, to allow configuring HW "offloaded" blinking of LEDs based on link state and activity (i.e. packets coming in and out)
- Support configuring rate selection pins of SFP modules
- Factor Clause 73 auto-negotiation code out of the drivers, provide common helper routines
- Add more fool-proof helpers for managing lifetime of MDIO devices associated with the PCS layer
- Allow drivers to report advanced statistics related to Time Aware scheduler offload (taprio)
- Allow opting out of VF statistics in link dump, to allow more VFs to fit into the message
- Split devlink instance and devlink port operations
New hardware / drivers:
- Ethernet: - Synopsys EMAC4 IP support (stmmac) - Marvell 88E6361 8 port (5x1GE + 3x2.5GE) switches - Marvell 88E6250 7 port switches - Microchip LAN8650/1 Rev.B0 PHYs - MediaTek MT7981/MT7988 built-in 1GE PHY driver
- WiFi: - Realtek RTL8192FU, 2.4 GHz, b/g/n mode, 2T2R, 300 Mbps - Realtek RTL8723DS (SDIO variant) - Realtek RTL8851BE
- CAN: - Fintek F81604

- Virtual NICs: - Microsoft vNIC: - size the Rx indirection table based on requested configuration - support VLAN tagging - Amazon vNIC: - try to reuse Rx buffers if not fully consumed, useful for ARM servers running with 16kB pages - Google vNIC: - support TCP segmentation of >64kB frames
- Ethernet embedded switches: - Marvell (mv88e6xxx): - enable USXGMII (88E6191X) - Microchip: - lan966x: add support for Egress Stage 0 ACL engine - lan966x: support mapping packet priority to internal switch priority (based on PCP or DSCP)
- Ethernet PHYs: - Broadcom PHYs: - support for Wake-on-LAN for BCM54210E/B50212E - report LPI counter - Microsemi PHYs: support RGMII delay configuration (VSC85xx) - Micrel PHYs: receive timestamp in the frame (LAN8841) - Realtek PHYs: support optional external PHY clock - Altera TSE PCS: merge the driver into Lynx PCS which it is a variant of
- CAN: Kvaser PCIEcan: - support packet timestamping
- WiFi: - Intel (iwlwifi): - major update for new firmware and Multi-Link Operation (MLO) - configuration rework to drop test devices and split the different families - support for segmented PNVM images and power tables - new vendor entries for PPAG (platform antenna gain) feature - Qualcomm 802.11ax (ath11k): - Multiple Basic Service Set Identifier (MBSSID) and Enhanced MBSSID Advertisement (EMA) support in AP mode - support factory test mode - RealTek (rtw89): - add RSSI based antenna diversity - support U-NII-4 channels on 5 GHz band - RealTek (rtl8xxxu): - AP mode support for 8188f - support USB RX aggregation for the newer chips"

Merge tag '5.17-net-next' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski: "Core ----
- Defer freeing TCP skbs to the BH handler, whenever possible, or at least perform the freeing outside of the socket lock section to decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice and net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via appropriate helpers to allow us to keep addresses in ordered data structures.
- Replace unix_table_lock with per-hash locks, improving performance of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF ---
- New helpers: - bpf_find_vma(), find and inspect VMAs for profiling use cases - bpf_loop(), runtime-bounded loop helper trading some execution time for much faster (if at all converging) verification - bpf_strncmp(), improve performance, avoid compiler flakiness - bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt() for tracing programs, all inlined by the verifier
- Support BPF relocations (CO-RE) in the kernel loader.
- Further the support for BTF_TYPE_TAG annotations.
- Allow access to local storage in sleepable helpers.
- Convert verifier argument types to a composable form with different attributes which can be shared across types (ro, maybe-null).
- Prepare libbpf for upcoming v1.0 release by cleaning up APIs, creating new, extensible ones where missing and deprecating those to be removed.
Protocols ---------
- WiFi (mac80211/cfg80211): - notify user space about long "come back in N" AP responses, allow it to react to such temporary rejections - allow non-standard VHT MCS 10/11 rates - use coarse time in airtime fairness code to save CPU cycles
- Bluetooth: - rework of HCI command execution serialization to use a common queue and work struct, and improve handling errors reported in the middle of a batch of commands - rework HCI event handling to use skb_pull_data, avoiding packet parsing pitfalls - support AOSP Bluetooth Quality Report
- SMC: - support net namespaces, following the RDMA model - improve connection establishment latency by pre-clearing buffers - introduce TCP ULP for automatic redirection to SMC
- Multi-Path TCP: - support ioctls: SIOCINQ, OUTQ, and OUTQNSD - support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT, IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY - support cmsgs: TCP_INQ - improvements in the data scheduler (assigning data to subflows) - support fastclose option (quick shutdown of the full MPTCP connection, similar to TCP RST in regular TCP)
- MCTP (Management Component Transport) over serial, as defined by DMTF spec DSP0253 - "MCTP Serial Transport Binding".
Driver API ----------
- Support timestamping on bond interfaces in active/passive mode.
- Introduce generic phylink link mode validation for drivers which don't have any quirks and where MAC capability bits fully express what's supported. Allow PCS layer to participate in the validation. Convert a number of drivers.

Merge branch 'introduce bpf_strncmp() helper'
Hou Tao says:
====================
Hi,
The motivation for introducing bpf_strncmp() helper comes from two aspects:
(1) clang doesn't always replace strncmp() automatically In tracing program, sometimes we need to using a home-made strncmp() to check whether or not the file name is expected.
(2) the performance of home-made strncmp is not so good As shown in the benchmark in patch #4, the performance of bpf_strncmp() helper is 18% or 33% better than home-made strncmp() under x86-64 or arm64 when the compared string length is 64. When the string length grows to 4095, the performance win will be 179% or 600% under x86-64 or arm64.
Any comments are welcome. Regards, Tao
Change Log: v2: * rebased on bpf-next * drop patch "selftests/bpf: factor out common helpers for benchmarks" (suggested by Andrii) * remove unnecessary inline functions and add comments for programs which will be rejected by verifier in patch 4 (suggested by Andrii) * rename variables used in will-fail programs to clarify the purposes.
v1: https://lore.kernel.org/bpf/20211130142215.1237217-1-houtao1@huawei.com * change API to bpf_strncmp(const char *s1, u32 s1_sz, const char *s2) * add benchmark refactor and benchmark between bpf_strncmp() and strncmp()
