Adds commonly used IPv6 packet header macros similar to what is available
on NetBSD and FreeBSD in sys/netinet/ip6.h and Android in
libc/include/netinet/ip6.h
Usage example IPV6_VERSION_MASK and IPV6_VERSION:
if ((ip6->ip6_vfc & IPV6_VERSION_MASK) == IPV6_VERSION)
return true;
Usage example IPV6_FLOWINFO_MASK:
ip6->ip6_flow = (flow & IPV6_FLOWINFO_MASK);
The relevant standard is RFC2460 (Internet Protocol, Version 6
Specification). It defines the Internet Protocol version (IPV6_VERSION)
and reduced the size of the flow label field from 24 to 20 bits
(IPV6_FLOWLABEL_MASK). The traffic class and flow label fields together
make up the flow information (IPV6_FLOWINFO_MASK).
Tested on x86_64 GNU/Linux

Linux 6.11 adds a define IPPROTO_SMC to its include/uapi/linux/in.h
(commit d25a92ccae6b).
Checked on x86_64-linux-gnu.

socket: Use may_alias on sockaddr structs (bug 19622)2024-05-18T07:33:19ZFlorian Weimerfweimer@redhat.com2024-05-18T07:33:19Zurn:sha1:8d7b6b4cb27d4dec1dd5f7960298c1699275f962
This supports common coding patterns. The GCC C front end before
version 7 rejects the may_alias attribute on a struct definition
if it was not present in a previous forward declaration, so this
attribute can only be conditionally applied.
This implements the spirit of the change in Austin Group issue 1641.

Linux 6.1 adds a define IPPROTO_L2TP to its include/uapi/linux/in.h
(not strictly a new constant, since it's moved from
include/uapi/linux/l2tp.h). Add this constant to glibc's
netinet/in.h.
Tested for x86_64.

It is following both the BSD and Linux definitions.
