Merge tag 'net-next-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull networking updates from Jakub Kicinski: "One of the 'small improvements all over the place' releases for us. It's hard to draw any direct comparisons because summer vacations disrupted our patch processing (and presumably - generation) quite a bit. Quick and dirty count suggests we (Paolo and I) merged a very similar number of net (632) and net-next (648) patches. This is not telling the full story either because 1/3 to 1/2 of the net-next patches also *seem* like AI-driven low priority fixes, cleanups and clarifications. We are completely overwhelmed, of course. The glimmer of hope is that we secured sufficient LLM budget and access (thank you Meta!) to run reviews with multiple frontier models on each patch. This eliminates some hallucinations. That said, in terms of review, the LLMs can only do so much. The sad truth is that our APIs (especially for rare events like PCIe errors, timeouts etc) have always been racy, and now LLMs don't let us ignore that. I expect our direction for the next release will be to tweak the reviews a little bit more, but start shifting focus to letting the LLMs take care of the busy work - managing patchwork, automating common process complaints, editing commit messages, and maybe applying patches which already got "reviewed-by" tags from people we trust... Core & protocols: - A few steps lowering rtnl_lock dependence: - per-netns netdev unregistration for select SW drivers (e.g. veth, ipvlan, tunnels) - rtnl_lock-less FIB rule changes (RTM_NEWRULE and RTM_DELRULE) - prepare software drivers and TC qdiscs for rtnl_lock-less GET - Support BIG TCP (>64kB TSO) in UDP tunnels (vxlan, geneve) - Support buffers larger than PAGE_SIZE in devmem zero-copy API - Improve MPTCP handling of extreme memory pressure handling, when out-of-order queue had to be pruned - Report the per-group user count via RTM_GETMULTICAST - Expose the route deletion reason in RTM_DELROUTE - Add a SO_RIGHTS_NOTRUNC option to UNIX sockets to enable more useful handling of LSM denials when receiving SCM_RIGHTS messages: instead of truncating the message at the first blocked fd, keep every fd slot and store the LSM errno in the blocked slot - IPv6 Segment Routing - support looking up the post-encap SID (address) in a different/specified routing table - Support PRP RedBox (interlink) creation - Support per-nexthop UDP dst port in VXLAN - Continue converting getsockopt callbacks in a number of protocols to iov_iter Ethernet: -

Thu, 13 Aug 2026 21:02:40 +0200

net: dsa: initial MT7628 tagging driverAdd support for the MT7628 embedded switch's tag.The MT7628 tag is merged with the VLAN TPID field when a VLAN isappended by the switch hardware. It is not installed if the VLAN tag isalready there on ingress. Due to this hardware quirk the tag cannot betrusted for port 0 if we don't know that the VLAN was added by thehardware. As a workaround for this the switch is configured to alwaysappend the port PVID tag even if the incoming packet is already tagged.The tagging driver can then trust that the tag is always accurate andthe whole VLAN tag can be removed on ingress as it's only metadata forthe tagger.On egress the MT7628 tag allows precise TX, but the correct VLAN tagfrom tag_8021q is still appended or the switch will not forward thepacket.Signed-off-by: Joris Vaisvila Link: https://patch.msgid.link/20260813190241.789323-4-joey@tinyisr.comSigned-off-by: Paolo Abeni List of files: /linux/net/dsa/Makefile

Merge tag 'net-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull networking updates from Jakub Kicinski: "Core & protocols: - Work on removing rtnl_lock protection throughout the stack continues. In this chapter: - don't use rtnl_lock for IPv6 multicast routing configuration - don't take rtnl_lock in ethtool for modern drivers - prepare Qdisc dump callbacks for rtnl_lock removal - Support dumping just ifindex + name of all interfaces, under RCU. It's a common operation for Netlink CLI tools (when translating names to ifindexes) and previously required full rtnl_lock. - Support dumping qdiscs and page pools for a specific netdev. Even tho user space wants a dump of all netdevs, most of the time, the OOO programming model results in repeating the dump for each netdev. Which, in absence of a cache, leads to a O(n^2) behavior. - Flush nexthops once on multi-nexthop removal (e.g. when device goes down), another O(n^2) -> O(n) improvement. - Rehash locally generated traffic to a different nexthop on retransmit timeout. - Honor oif when choosing nexthop for locally generated IPv6 traffic. - Convert TCP Auth Option to crypto library, and drop non-RFC algos. - Increase subflow limits in MPTCP to 64 and endpoint limit to 256. - Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need to selectively skip reporting of the standard TCP Timestamp option, because they won't fit into the header space together (12 + 30 > 40). - Support using bridge neighbor suppression, Duplicate Address Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN deployments, e.g. VXLAN fabrics (IPv4 and IPv6). - Improve link state reporting for upper netdevs (e.g. macvlan) over tunnel devices (again, mostly for EVPN deployments). - Support binding GENEVE tunnels to a local address. - Speed up UDP tunnel destruction (remove one synchronize_rcu()). - Support exponential field encoding in multicast (IGMPv3 and MLDv2). - Support attaching PSP crypto offload to containers (veth, netkit). - Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows migrating individual IPsec SAs independently of their policies. The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA migration, lacks SPI for unique SA identification, and cannot express reqid changes or migrate Transport mode selectors. The new interface identifies the SA via SPI and mark, supports reqid changes, address family changes, encap removal, and uses an atomic create+install flow under x->lock to prevent SN/IV reuse during AEAD SA migration. - Implement GRO/GSO support for PPPoE. - Convert sockopt callbacks in a number of protocols to iov_iter. Cross-tree stuff: - Remove support for Crypto TFM cloning (unblocked after the TCP Auth Option rework). This feature regressed performance for all crypto API users, since it changed crypto transformation objects into reference-counted objects. - Add FCrypt-PCBC implementation to rxrpc and remove it from the global crypto API as obsolete and insecure. Wireless: - Major rework of station bandwidth handling, fixing issues with lower capability than AP. - Cleanups for EMLSR spec issues (drafts differed). - More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast, schedule improvements, multi-station etc.) - Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work (e.g. non-primary channel access, UHR DBE support). - Fine Timing Measurement ranging (i.e. distance measurement) APIs. Netfilter: - Use per-rule hash initval in nf_conncount. This avoids unnecessary lock contention with short keys (e.g. conntrack zones) in different namespaces. - Various safety improvements, both in packet parsing and object lifetimes. Notably add refcounts to conntrack timeout policy. Deletions: - Remove TLS + sockmap integration. TLS wants to pin user pages to avoid a copy, and sockmap wants to write to the input stream. More work on this integration is clearly needed, and we can't find any users (original author admitted that they never deployed it). - Remove support for TLS offload with TCP Offload Engine (the far more common opportunistic offload is retained). The locking looks unfixable (driver sleeps under TCP spin locks) and people from the vendor that added this are AWOL. - Remove more ATM code, trying to leave behind only what PPPoATM needs, AAL5 and br2684 with permanent circuits. - Remove AppleTalk. Let it join hamradio in our out of tree protocol graveyard, I mean, repository. - Disable 32-bit x_tables compatibility (32bit binaries on 64bit kernel) interface in user namespaces. To be deleted completely, soon. - Remove 5/10 MHz support from cfg80211/mac80211.

Merge branch 'add-preliminary-netc-switch-support-for-i-mx94'Wei Fang says:====================Add preliminary NETC switch support for i.MX94i.MX94 NETC (v4.3) integrates 802.1Q Ethernet switch functionality, theswitch provides advanced QoS with 8 traffic classes and a full range ofTSN standards capabilities. It has 3 user ports and 1 CPU port, and theCPU port is connected to an internal ENETC through the pseduo link, soinstead of a back-to-back MAC, the lightweight "pseudo MAC" is used atboth ends of the pseudo link to transfer Ethernet frames. The pseudolink provides a zero-copy interface (no serialization delay) and lowerpower (less logic and memory).Like most Ethernet switches, the NETC switch also supports a proprietaryswitch tag, is used to carry in-band metadata information about frames.This in-band metadata information can include the source port from whichthe frame was received, what was the reason why this frame got forwardedto the entity, and for the entity to indicate the precise destinationport of a frame. The NETC switch tag is added to frames after the sourceMAC address. There are three types of switch tags, and each type has 1to 4 subtypes, more details are as follows.Forward switch tag (Type = 0): Represents forwarded frames. - SubType = 0 - Normal frame processing.To_Port switch tag (Type = 1): Represents frames that are to be sent toa specific switch port. - SubType = 0. No request to perform timestamping. - SubType = 1. Request to perform one-step timestamping. - SubType = 2. Request to perform two-step timestamping. - SubType = 3. Request to perform both one-step timestamping and two-step timestamping.To_Host switch tag (Type = 2): Represents frames redirected or copied tothe switch management port. - SubType = 0. Received frames redirected or copied to the switch management port. - SubType = 1. Received frames redirected or copied to the switch management port with captured timestamp at the switch port where the frame was received. - SubType = 2. Transmit timestamp response (two-step timestamping).Currently, this patch set supports Forward tag, SubType 0 of To_Port tagand SubType 0 of To_Host tag. More tags will be supported in the future.In addition, the switch supports NETC Table Management Protocol (NTMP),some switch functionality is controlled using control messages sent tothe hardware using BD ring interface with 32B descriptors similar to thepacket Transmit BD ring used on ENETC. This interface is referred to asthe command BD ring. This is used to configure functionality where theunderlying resources may be shared between different entities or beingtoo large to configure using direct registers.For this patch set, we have supported the following tables through thecommand BD ring interface.FDB Table: It contains forwarding and/or filtering information about MACaddresses. The FDB table is used for MAC learning lookups and MACforwarding lookups.VLAN Filter Table: It contains configuration and control information foreach VLAN configured on the switch.Buffer Pool Table: It contains buffer pool configuration and operationalinformation. Each entry corresponds to a buffer pool. Currently, we usethis table to implement flow control feature on each port.Ingress Port Filter Table: It contains a set of filters each capable ofclassifying incoming traffic using a mix of L2, L3, and L4 parsed andarbitrary field data. We use this table to implement host flood supportto the switch port.The switch also supports other tables, and we will add more advancedfeatures through them in the future.====================Link: https://patch.msgid.link/20260518082506.1318236-1-wei.fang@nxp.comSigned-off-by: Paolo Abeni List of files: /linux/net/dsa/Makefile

0850005c26d2623f3d77489cf27d342191a97b5c - net: dsa: add NETC switch tag support

Mon, 18 May 2026 10:25:00 +0200

net: dsa: add NETC switch tag supportThe NXP NETC switch tag is a proprietary header added to frames after thesource MAC address. The switch tag has 3 types, and each type has 1 ~ 4subtypes, the details are as follows.Forward NXP switch tag (Type=0): Represents forwarded frames. - SubType = 0 - Normal frame processing.To_Port NXP switch tag (Type=1): Represents frames that are to be sentto a specific switch port. - SubType = 0. No request to perform timestamping. - SubType = 1. Request to perform one-step timestamping. - SubType = 2. Request to perform two-step timestamping. - SubType = 3. Request to perform both one-step timestamping and two-step timestamping.To_Host NXP switch tag (Type=2): Represents frames redirected or copiedto the switch management port. - SubType = 0. Received frames redirected or copied to the switch management port. - SubType = 1. Received frames redirected or copied to the switch management port with captured timestamp at the switch port where the frame was received. - SubType = 2. Transmit timestamp response (two-step timestamping).In addition, the length of different type switch tag is different, theminimum length is 6 bytes, the maximum length is 14 bytes. Currently,Forward tag, SubType 0 of To_Port tag and Subtype 0 of To_Host tag aresupported. More tags will be supported in the future.Signed-off-by: Wei Fang Link: https://patch.msgid.link/20260518082506.1318236-10-wei.fang@nxp.comSigned-off-by: Paolo Abeni List of files: /linux/net/dsa/Makefile
