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.

Pull 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.

  Drivers:

   - Software:
       - Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit)
       - bonding: add knob to strictly follow 802.3ad for link state

   - New drivers:
       - Alibaba Elastic Ethernet Adaptor (cloud vNIC).
       - NXP NETC switch within i.MX94.

             60% win for LRO on slow CPUs like ARM64 V2)
           - expose more per-queue stats over the standard API
           - support additional, unprivileged PFs in the DPU
             configuration
           - support Socket Direct (multi-PF) with switchdev offloads
           - add a pool / frag allocator for DMA mapped buffers for
             control objects, save memory on systems with 64kB page size
           - take advantage of the ability to dynamically change RSS
             table size, even when table is configured by the user
           - increase the max RSS table size for even traffic
             distribution
