Michael Kerrisk 14dd128c7c syscalls.2: Move system calls from discontinued ports out of main syscall list 
Various ports that had their own indigenous system calls have
been discontinued. Remove those system calls (none of which had
manual pages!) to a separate part of the page, to avoid
cluttering the main list of system calls.

Stephen Smalley 755b3ecb73 ip.7: Document IP_PASSSEC for UDP sockets 
Document the IP_PASSSEC socket option and SCM_SECURITY
ancillary/control message type for UDP sockets.

IP_PASSSEC for UDP sockets was introduced in Linux 2.6.17 [1].

Example NetLabel and IPSEC configurations and usage of this
option can be found in the SELinux Notebook [2] and SELinux
testsuite [3].

Stephen Smalley 3c63603499 socket.7,ip.7: Document SO_PEERSEC for AF_INET sockets 
Augment the description of SO_PEERSEC to cover AF_INET sockets in
addition to the prior description for AF_UNIX.

SO_PEERSEC for TCP sockets was introduced in Linux 2.6.17 [1], and
SO_PEERSEC for SCTP sockets was introduced in Linux 4.17 [2].

This does not cover usage of SCM_SECURITY for UDP sockets, which
was also introduced in the same commit for 2.6.17.

Examples of the necessary labeled IPSEC and NetLabel
configurations to enable use of SO_PEERSEC for TCP and SCTP
sockets can be found in the SELinux Notebook [3] and the
selinux-testsuite [4].

Stephen Smalley e6f90c3fb2 socket.7, unix.7: Add initial description for SO_PEERSEC 
SO_PEERSEC was introduced for AF_UNIX stream sockets connected via
connect(2) in Linux 2.6.2 [1] and later augmented to support
AF_UNIX stream and datagram sockets created via socketpair(2) in
Linux 4.18 [2].  Document SO_PEERSEC in the socket.7 and unix.7
man pages following the example of the existing SO_PEERCRED
descriptions.  SO_PEERSEC is also supported on AF_INET sockets
when using labeled IPSEC or NetLabel but defer adding a
description of that support to a separate patch.

The module-independent description of the security context
returned by SO_PEERSEC is from Simon McVittie.
