Merge tag 'net-next-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls)

- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.

- Support collecting TCP timestamps (data submitted, sent, acked) in
BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.

- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.

- Optimize MPTCP performance in single subflow mode by 29%.

- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream
performance up to 2x.

- Improve performance of contended connect() by 200% by searching for
an available 4-tuple under RCU rather than a spin lock. Bring an
additional 229% improvement by tweaking hash distribution.

- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.

- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.

- Avoid FIB lookup in netfilter if socket is available, 20% perf win.

- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles. There are up to 4
namespace roles but we used to have just 2 netns pointer arguments,
interpreted differently based on context.

- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.

- Add a new sysctl and sockopt for capping max retransmit timeout in
TCP.

- Support masking port and DSCP in routing rule matches.

- Support dumping IPv4 multicast addresses with RTM_GETMULTICAST.

- Support specifying at what time packet should be sent on AF_XDP
sockets.

- Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin
users.

- Add Netlink YAML spec for WiFi (nl80211) and conntrack.

- Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols
which only need to be exported when IPv6 support is built as a
module.

- Age FDB entries based on Rx not Tx traffic in VxLAN, similar to
normal bridging.

- Allow users to specify source port range for GENEVE tunnels.

- netconsole: allow attaching kernel release, CPU ID and task name to
messages as metadata

Driver API:

- Continue rework / fixing of Energy Efficient Ethernet (EEE) across
the SW layers. Delegate the responsibilities to phylink where
possible. Improve its handling in phylib.

Merge branch 'eth-mlx4-use-the-page-pool-for-rx-buffers'

Jakub Kicinski says:

====================
eth: mlx4: use the page pool for Rx buffers

Convert mlx4 to page pool. I've been sitting on these patches for
over a year, and Jonathan Lemon had a similar series years before.
We never deployed it or sent upstream because it didn't really show
much perf win under normal load (admittedly I think the real testing
was done before Ilias's work on recycling).

During the v6.9 kernel rollout Meta's CDN team noticed that machines
with CX3 Pro (mlx4) are prone to overloads (double digit % of CPU time
spent mapping buffers in the IOMMU). The problem does not occur with
modern NICs, so I dusted off this series and reportedly it still works.
And it makes the problem go away, no overloads, perf back in line with
older kernels. Something must have changed in IOMMU code, I guess.

This series is very simple, and can very likely be optimized further.
Thing is, I don't have access to any CX3 Pro NICs. They only exist
in CDN locations which haven't had a HW refresh for a while. So I can
say this series survives a week under traffic w/ XDP enabled, but
my ability to iterate and improve is a bit limited.

eth: mlx4: create a page pool for Rx

Create a pool per rx queue. Subsequent patches will make use of it.

Move fcs_del to a hole to make space for the pointer.

Per common "wisdom" base the page pool size on the ring size.
Note that the page pool cache size is in full pages, so just
round up the effective buffer size to pages.
