Thu, 04 Dec 2025 02:24:33 +0100

Merge tag 'net-next-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull networking updates from Jakub Kicinski: "Core & protocols: - Replace busylock at the Tx queuing layer with a lockless list. Resulting in a 300% (4x) improvement on heavy TX workloads, sending twice the number of packets per second, for half the cpu cycles. - Allow constantly busy flows to migrate to a more suitable CPU/NIC queue. Normally we perform queue re-selection when flow comes out of idle, but under extreme circumstances the flows may be constantly busy. Add sysctl to allow periodic rehashing even if it'd risk packet reordering. - Optimize the NAPI skb cache, make it larger, use it in more paths. - Attempt returning Tx skbs to the originating CPU (like we already did for Rx skbs). - Various data structure layout and prefetch optimizations from Eric. - Remove ktime_get() from the recvmsg() fast path, ktime_get() is sadly quite expensive on recent AMD machines. - Extend threaded NAPI polling to allow the kthread busy poll for packets. - Make MPTCP use Rx backlog processing. This lowers the lock pressure, improving the Rx performance. - Support memcg accounting of MPTCP socket memory. - Allow admin to opt sockets out of global protocol memory accounting (using a sysctl or BPF-based policy). The global limits are a poor fit for modern container workloads, where limits are imposed using cgroups. - Improve heuristics for when to kick off AF_UNIX garbage collection. - Allow users to control TCP SACK compression, and default to 33% of RTT. - Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid unnecessarily aggressive rcvbuf growth and overshot when the connection RTT is low. - Preserve skb metadata space across skb_push / skb_pull operations. - Support for IPIP encapsulation in the nftables flowtable offload. - Support appending IP interface information to ICMP messages (RFC 5837). - Support setting max record size in TLS (RFC 8449). - Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL. - Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock. - Let users configure the number of write buffers in SMC. - Add new struct sockaddr_unsized for sockaddr of unknown length, from Kees. - Some conversions away from the crypto_ahash API, from Eric Biggers. - Some preparations for slimming down struct page. - YAML Netlink protocol spec for WireGuard. - Add a tool on top of YAML Netlink specs/lib for reporting commonly computed derived statistics and summarized system state. Driver API: - Add CAN XL support to the CAN Netlink interface. - Add uAPI for reporting PHY Mean Square Error (MSE) diagnostics, as defined by the OPEN Alliance's "Advanced diagnostic features for 100BASE-T1 automotive Ethernet PHYs" specification. - Add DPLL phase-adjust-gran pin attribute (and implement it in zl3073x). - Refactor xfrm_input lock to reduce contention when NIC offloads IPsec and performs RSS. - Add info to devlink params whether the current setting is the default or a user override. Allow resetting back to default. - Add standard device stats for PSP crypto offload. - Leverage DSA frame broadcast to implement simple HSR frame duplication for a lot of switches without dedicated HSR offload. - Add uAPI defines for 1.6Tbps link modes. Device drivers: - Add Motorcomm YT921x gigabit Ethernet switch support. - Add MUCSE driver for N500/N210 1GbE NIC series. - Convert drivers to support dedicated ops for timestamping control, and away from the direct IOCTL handling. While at it support GET operations for PHY timestamping. - Add (and convert most drivers to) a dedicated ethtool callback for reading the Rx ring count. - Significant refactoring efforts in the STMMAC driver, which supports Synopsys turn-key MAC IP integrated into a ton of SoCs. -

Mon, 10 Nov 2025 20:10:09 +0100

Merge branch 'net-smc-introduce-smc_hs_ctrl'D. Wythe says:====================net/smc: Introduce smc_hs_ctrlThis patch aims to introduce BPF injection capabilities for SMC andincludes a self-test to ensure code stability.Since the SMC protocol isn't ideal for every situation, especiallyshort-lived ones, most applications can't guarantee the absence ofsuch scenarios. Consequently, applications may need specific strategiesto decide whether to use SMC. For example, an application might limit SMCusage to certain IP addresses or ports.To maintain the principle of transparent replacement, we want applicationsto remain unaffected even if they need specific SMC strategies. In otherwords, they should not require recompilation of their code.Additionally, we need to ensure the scalability of strategy implementation.While using socket options or sysctl might be straightforward, it couldcomplicate future expansions.Fortunately, BPF addresses these concerns effectively. Users can writetheir own strategies in eBPF to determine whether to use SMC, and they caneasily modify those strategies in the future.This is a rework of the series from [1]. Changes since [1] are limited tothe SMC parts:1. Rename smc_ops to smc_hs_ctrl and change interface name.2. Squash SMC patches, removing standalone non-BPF hook capability.3. Fix typos[1]: https://lore.kernel.org/bpf/20250123015942.94810-1-alibuda@linux.alibaba.com/#tv2 -> v1: - Removed the fixes patch, which have already been merged on current branch. - Fixed compilation warning of smc_call_hsbpf() when CONFIG_SMC_HS_CTRL_BPF is not enabled. - Changed the default value of CONFIG_SMC_HS_CTRL_BPF to Y. - Fix typo and renamed some variablesv3 -> v2: - Removed the libbpf patch, which have already been merged on current branch. - Fixed sparse warning of smc_call_hsbpf() and xchg().v4 -> v3: - Rebased on latest bpf-next, updated SMC loopback config from SMC_LO to DIBS_LO per upstream changes.v5 -> v4: - Removed the redundant sk parameter from smc_call_hsbpf - Reject registration when bpf_link is set, link support will be added in the future. - Updated selftests with new test heplers.====================Link: https://patch.msgid.link/20251107035632.115950-1-alibuda@linux.alibaba.comSigned-off-by: Martin KaFai Lau List of files: /linux/net/smc/Makefile

Fri, 07 Nov 2025 04:56:31 +0100

net/smc: bpf: Introduce generic hook for handshake flowThe introduction of IPPROTO_SMC enables eBPF programs to determinewhether to use SMC based on the context of socket creation, such asnetwork namespaces, PID and comm name, etc.As a subsequent enhancement, to introduce a new generic hook thatallows decisions on whether to use SMC or not at runtime, includingbut not limited to local/remote IP address or ports.User can write their own implememtion via bpf_struct_ops now to choosewhether to use SMC or not before TCP 3rd handshake to be comleted.Signed-off-by: D.
