glibc/posix/gai.conf
Ulrich Drepper 77dd4c3be8 * sysdeps/posix/getaddrinfo.c: Implement configuration file
handling.  /etc/gai.conf can contain replacements for the label
	and precedence table.  Fix byte order of default label and
	precedence table.
	* posix/gai.conf: New file.
	* posix/tst-rfc3484.c: Adjust for changes to getaddrinfo.c.
	* posix/tst-rfc3484-2.c: Likewise.

# Configuration for getaddrinfo(3).
#
# So far only configuration for the destination address sorting is needed.
# RFC 3484 governs the sorting. But the RFC also says that system
# administrators should be able to overwrite the defaults. This can be
# achieved here.
#
# All lines have an initial identifier specifying the option followed by
# up to two values. Information specified in this file replaces the
# default information. Complete absence of data of one kind causes the
# appropriate default information to be used. The supported commands include:
#
# reload <yes|no>
# If set to yes, each getaddrinfo(3) call will check whether this file
# changed and if necessary reload. This option should not really be
# used. There are possible runtime problems. The default is no.
#
# label <mask> <value>
# Add another rule to the RFC 3484 label table. See section 2.1 in
# RFC 3484. The default is:
#
#label ::1/128 0
#label ::/0 1
#label 2002::/16 2
#label ::/96 3
#label ::ffff:0:0/96 4
#
# precedence <mask> <value>
# Add another rule the to RFC 3484 precendence table. See section 2.1
# and 10.3 in RFC 3484. The default is:
#
#precendence ::1/128 50
#precendence ::/0 40
#precendence 2002::/16 30
#precendence ::/96 20
#precendence ::ffff:0:0/96 10
#
# For sites which prefer IPv4 connections change the last line to
#
#precendence ::ffff:0:0/96 100
