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.

README

This package contains Linux man pages for sections 1 through 8.  Some
more information is given in the 'man-pages-x.y.Announce' file.

Homepage

For information about the Linux man-pages project, see
http://www.kernel.org/doc/man-pages/index.html.

Bug reports and contributing
============================
If you have corrections and additions to suggest, see
http://www.kernel.org/doc/man-pages/contributing.html
(Although there is a mirror of this repository on GitHub,
please don't report issues via the GitHub issue tracker!)

For further information on contributing, see the CONTRIBUTING file.

Installing and uninstalling
===========================
"make install" will copy these man pages to /usr/share/man/man[1-8].

To install to a path different from /usr, use
"make install prefix=/install/path".

"make remove" or "make uninstall" will remove any man page in this
distribution from its destination.  Use with caution, and remember to
use "prefix" if desired, as with the "install" target.

"make" or "make all" will perform "make uninstall" followed by "make
install".
