Recently, IPV6_ADDRFORM has received many AI-driven bug reports.
Fixing them properly would needlessly churn the fast paths in TCP
and UDP.
IPV6_ADDRFORM was initially introduced in RFC 2133 in 1997,
but only two years later, it was removed from RFC 2553 in 1999.
In 2026, modern applications natively support dual-stack sockets;
notably, systemd's socket activation does not use IPV6_ADDRFORM.
Also, getsockopt(IPV6_ADDRFORM) can be replaced with SO_DOMAIN.
Let's remove IPV6_ADDRFORM.
Later, we can remove sk->sk_prot_creator and revert commit
c26c192c3d ("udp: properly deal with xfrm encap and ADDRFORM").

Nikolay Aleksandrov says:
====================
net: bridge: vlan: minor cleanups and annotations
In preparation for a complete vlan fast-path re-work, this set cleans up
a few minor things - removing legacy code barriers that don't help,
annotating lockless accesses and using proper helpers.
No functional changes are intended. Sashiko will find many pre-existing
problems, none of them are related to this set. I will try to fix
everything pre-existing separately in -net, there will probably be a few
critical items. So if there are missed places to annotate, or if there're
actual functional changes, these obviously should be addressed in this set.

The vlan state can change under RTNL or RCU (mst), so use the helper
to get the state properly throughout the bridge driver.

These memory barriers are legacy code from the old vlan implementation
that is not needed anymore. They're also affecting the fast-path.
The pvid is changed under lock and is read with rcu only in the fast-path
there is no need for a barrier, nothing to commit prior to changing it nor
invalidate prior to reading.

The issue was discovered via smatch static analyzer:
make CHECK="smatch -p=kernel" C=2 drivers/net/phy/microchip_t1.o
CHECK scripts/mod/empty.c
DESCEND objtool
CHECK drivers/net/phy/microchip_t1.c
drivers/net/phy/microchip_t1.c:1295 lan887x_phy_init() warn: 'priv->clock' can also be NULL
mchp_rds_ptp_probe() returns NULL when CONFIG_MICROCHIP_PHY_RDS_PTP or
CONFIG_PTP_1588_CLOCK is disabled. However, lan887x_phy_init() only checks
for an error pointer before using the returned clock to configure the
periodic output pin, which can result in a NULL pointer dereference.
Handle the NULL return as PTP being unavailable and skip the event pin
configuration in that case. Smatch no longer reports the NULL dereference
warning after the change.
