[GIT PULL] selinux/selinux-pr-20240911

[Paul Moore <paul@paul-moore.com>]

Linus,

A number of small SELinux patches for the v6.12 merge window:

* Ensure that both IPv4 and IPv6 connections are properly initialized

While we always properly initialized IPv4 connections early in their
life, we missed the necessary IPv6 change when we were adding IPv6
support.

* Annotate the SELinux inode revalidation function to quiet KCSAN 

KCSAN correctly identifyies a race in __inode_security_revalidate() when
we check to see if an inode's SELinux has been properly initialized.
While KCSAN is correct, it is an intentional choice made for performance
reasons; if necessary, we check the state a second time, this time with a
lock held, before initializing the inode's state.

* Code cleanups, simplification, etc.

A handful of individual patches to simplify some SELinux kernel logic,
improve return code granularity via ERR_PTR(), follow the guidance on
using KMEM_CACHE(), and correct some minor style problems.

-Paul
