tcp: Fix bind() regression for v4-mapped-v6 wildcard address.
Andrei Vagin reported bind() regression with strace logs.
If we bind() a TCPv6 socket to ::FFFF:0.0.0.0 and then bind() a TCPv4 socket to 127.0.0.1, the 2nd bind() should fail but now succeeds.
from socket import *
s1 = socket(AF_INET6, SOCK_STREAM) s1.bind(('::ffff:0.0.0.0', 0))
s2 = socket(AF_INET, SOCK_STREAM) s2.bind(('127.0.0.1', s1.getsockname()[1]))
During the 2nd bind(), if tb->family is AF_INET6 and sk->sk_family is AF_INET in inet_bind2_bucket_match_addr_any(), we still need to check if tb has the v4-mapped-v6 wildcard address.
The example above does not work after commit 5456262d2baa ("net: Fix incorrect address comparison when searching for a bind2 bucket"), but the blamed change is not the commit.
Before the commit, the leading zeros of ::FFFF:0.0.0.0 were treated as 0.0.0.0, and the sequence above worked by chance. Technically, this case has been broken since bhash2 was introduced.
Note that if we bind() two sockets to 127.0.0.1 and then ::FFFF:0.0.0.0, the 2nd bind() fails properly because we fall back to using bhash to detect conflicts for the v4-mapped-v6 address.

Merge tag 'sysctl-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux
Pull sysctl updates from Luis Chamberlain: "Long ago we set out to remove the kitchen sink on kernel/sysctl.c arrays and placings sysctls to their own sybsystem or file to help avoid merge conflicts. Matthew Wilcox pointed out though that if we're going to do that we might as well also *save* space while at it and try to remove the extra last sysctl entry added at the end of each array, a sentintel, instead of bloating the kernel by adding a new sentinel with each array moved.
Doing that was not so trivial, and has required slowing down the moves of kernel/sysctl.c arrays and measuring the impact on size by each new move.
The complex part of the effort to help reduce the size of each sysctl is being done by the patient work of el señor Don Joel Granados. A lot of this is truly painful code refactoring and testing and then trying to measure the savings of each move and removing the sentinels. Although Joel already has code which does most of this work, experience with sysctl moves in the past shows is we need to be careful due to the slew of odd build failures that are possible due to the amount of random Kconfig options sysctls use.
To that end Joel's work is split by first addressing the major housekeeping needed to remove the sentinels, which is part of this merge request. The rest of the work to actually remove the sentinels will be done later in future kernel releases.
The preliminary math is showing this will all help reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array where we are able to remove each sentinel in the future. That also means there is no more bloating the kernel with the extra ~64 bytes per array moved as no new sentinels are created"

In this series, I converted 20 bits in "struct inet_sock" and made them truly atomic.
This allows to implement many IP_ socket options in a lockless fashion (no need to acquire socket lock), and fixes data-races that were showing up in various KCSAN reports.
I also took care of IP_TTL/IP_MINTTL, but left few other options for another series.

networking: Update to register_net_sysctl_sz
Move from register_net_sysctl to register_net_sysctl_sz for all the networking related files. Do this while making sure to mirror the NULL assignments with a table_size of zero for the unprivileged users.
We need to move to the new function in preparation for when we change SIZE_MAX to ARRAY_SIZE() in the register_net_sysctl macro. Failing to do so would erroneously allow ARRAY_SIZE() to be called on a pointer. We hold off the SIZE_MAX to ARRAY_SIZE change until we have migrated all the relevant net sysctl registering functions to register_net_sysctl_sz in subsequent commits.
An additional size function was added to the following files in order to calculate the size of an array that is defined in another file: include/net/ipv6.h net/ipv6/icmp.c net/ipv6/route.c net/ipv6/sysctl_net_ipv6.c

Merge branch 'mptcp-remove-msk-subflow'
Matthieu Baerts says:
==================== mptcp: get rid of msk->subflow
The MPTCP protocol maintains an additional struct socket per connection, mainly to be able to easily use tcp-level struct socket operations.
This leads to several side effects, beyond the quite unfortunate / confusing 'subflow' field name:
- active and passive sockets behaviour is inconsistent: only active ones have a not NULL msk->subflow, leading to different error handling and different error code returned to the user-space in several places.
- active sockets uses an unneeded, larger amount of memory
- passive sockets can't successfully go through accept(), disconnect(), accept() sequence, see [1] for more details.
The 13 first patches of this series are from Paolo and address all the above, finally getting rid of the blamed field:
- The first patch is a minor clean-up.
- In the next 11 patches, msk->subflow usage is systematically removed from the MPTCP protocol, replacing it with direct msk->first usage, eventually introducing new core helpers when needed.
- The 13th patch finally disposes the field, and it's the only patch in the series intended to produce functional changes.
The last and 14th patch is from Kuniyuki and it is not linked to the previous ones: it is a small clean-up to get rid of an unnecessary check in mptcp_init_sock().

net: factor out inet{,6}_bind_sk helpers
The mptcp protocol maintains an additional socket just to easily invoke a few stream operations on the first subflow. One of them is bind().
Factor out the helpers operating directly on the struct sock, to allow get rid of the above dependency in the next patch without duplicating the existing code.
No functional changes intended.
