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.

Device drivers:

Merge branch 'net-improve-netns-handling-in-rtnetlink'

Xiao Liang says:

====================
net: Improve netns handling in rtnetlink

This patch series includes some netns-related improvements and fixes for
rtnetlink, to make link creation more intuitive:

1) Creating link in another net namespace doesn't conflict with link
names in current one.
2) Refector rtnetlink link creation. Create link in target namespace
directly.

So that

# ip link add netns ns1 link-netns ns2 tun0 type gre ...

will create tun0 in ns1, rather than create it in ns2 and move to ns1.
And don't conflict with another interface named "tun0" in current netns.

Patch 01 avoids link name conflict in different netns.

To achieve 2), there're mainly 3 steps:

- Patch 02 packs newlink() parameters into a struct, including
the original "src_net" along with more netns context. No semantic
changes are introduced.
- Patch 03 ~ 09 converts device drivers to use the explicit netns
extracted from params.
- Patch 10 ~ 11 removes the old netns parameter, and converts
rtnetlink to create device in target netns directly.

Patch 12 ~ 13 adds some tests for link name and link netns.

---

Please note there're some issues found in current code:

- In amt_newlink() drivers/net/amt.c:

amt->net = net;
...
amt->stream_dev = dev_get_by_index(net, ...

Uses net, but amt_lookup_upper_dev() only searches in dev_net.
So the AMT device may not be properly deleted if it's in a different
netns from lower dev.

- In lowpan_newlink() in net/ieee802154/6lowpan/core.c:

wdev = dev_get_by_index(dev_net(ldev), nla_get_u32(tb[IFLA_LINK]));

Looks for IFLA_LINK in dev_net, but in theory the ifindex is defined
in link netns.

rtnetlink: Pack newlink() params into struct

There are 4 net namespaces involved when creating links:

- source netns - where the netlink socket resides,
- target netns - where to put the device being created,
- link netns - netns associated with the device (backend),
- peer netns - netns of peer device.

Currently, two nets are passed to newlink() callback - "src_net"
parameter and "dev_net" (implicitly in net_device). They are set as
follows, depending on netlink attributes in the request.

+------------+-------------------+---------+---------+
| peer netns | IFLA_LINK_NETNSID | src_net | dev_net |
+------------+-------------------+---------+---------+
| | absent | source | target |
| absent +-------------------+---------+---------+
| | present | link | link |
+------------+-------------------+---------+---------+
| | absent | peer | target |
| present +-------------------+---------+---------+
| | present | peer | link |
+------------+-------------------+---------+---------+

When IFLA_LINK_NETNSID is present, the device is created in link netns
first and then moved to target netns. This has some side effects,
including extra ifindex allocation, ifname validation and link events.
These could be avoided if we create it in target netns from
the beginning.

On the other hand, the meaning of src_net parameter is ambiguous. It
varies depending on how parameters are passed. It is the effective
link (or peer netns) by design, but some drivers ignore it and use
dev_net instead.

To provide more netns context for drivers, this patch packs existing
newlink() parameters, along with the source netns, link netns and peer
netns, into a struct. The old "src_net" is renamed to "net" to avoid
confusion with real source netns, and will be deprecated later. The use
of src_net are converted to params->net trivially.
