- * 5-Oct-2000 W. Greathouse wgreathouse@smva.com
|
|
|
- * Fix memory leak and memory corruption.
|
|
|
- * -- Every name resolution resulted in
|
|
|
- * a new parse of resolv.conf and new
|
|
|
- * copy of nameservers allocated by
|
|
|
- * strdup.
|
|
|
- * -- Every name resolution resulted in
|
|
|
- * a new read of resolv.conf without
|
|
|
- * resetting index from prior read...
|
|
|
- * resulting in exceeding array bounds.
|
|
|
- *
|
|
|
- * Limit nameservers read from resolv.conf.
|
|
|
- * Add "search" domains from resolv.conf.
|
|
|
- * Some systems will return a security
|
|
|
- * signature along with query answer for
|
|
|
- * dynamic DNS entries -- skip/ignore this answer.
|
|
|
- * Include arpa/nameser.h for defines.
|
|
|
- * General cleanup.
|
|
|

|
|
|
- * 20-Jun-2001 Michal Moskal <malekith@pld.org.pl>
|
|
|
- * partial IPv6 support (i.e. gethostbyname2() and resolve_address2()
|
|
|
- * functions added), IPv6 nameservers are also supported.
|
|
|
- *
|
|
|
- * 6-Oct-2001 Jari Korva <jari.korva@iki.fi>
|
|
|
- * more IPv6 support (IPv6 support for gethostbyaddr();
|
|
|
- * address family parameter and improved IPv6 support for get_hosts_byname
|
|
|
- * and read_etc_hosts; getnameinfo() port from glibc; defined
|
|
|
- * defined ip6addr_any and in6addr_loopback)
|
|
|
- *
|
|
|
- * 2-Feb-2002 Erik Andersen <andersen@codepoet.org>
|
|
|
- * Added gethostent(), sethostent(), and endhostent()
|
|
|
- *
|
|
|
- * 17-Aug-2002 Manuel Novoa III <mjn3@codepoet.org>
|
|
|
- * Fixed __read_etc_hosts_r to return alias list, and modified buffer
|
|
|
- * allocation accordingly. See MAX_ALIASES and ALIAS_DIM below.
|
|
|
- * This fixes the segfault in the Python 2.2.1 socket test.

|

|
|
|
- * 04-Jan-2003 Jay Kulpinski <jskulpin@berkshire.rr.com>
|
|
|
- * Fixed __decode_dotted to count the terminating null character
|
|
|
- * in a host name.
|
|
|
- *
|
|
|
- * 02-Oct-2003 Tony J. White <tjw@tjw.org>
|
|
|
- * Lifted dn_expand() and dependent ns_name_uncompress(), ns_name_unpack(),
|
|
|
- * and ns_name_ntop() from glibc 2.3.2 for compatibility with ipsec-tools
|
|
|
- * and openldap.
|
|
|
- *
|
|
|
- * 7-Sep-2004 Erik Andersen <andersen@codepoet.org>
|
|
|
- * Added gethostent_r()
|
|
|
- *
|
|
|
- * 2008, 2009 Denys Vlasenko <vda.linux@googlemail.com>
|
|
|
- * Cleanups, fixes, readability, more cleanups and more fixes.
|
|
|
- *
|
|
|
- * March 2010 Bernhard Reutner-Fischer
|
|
|
- * Switch to common config parser

-/* Nota bene:
|
|
|
- * The whole resolver code has several (severe) problems:
|
|
|
- * - it doesn't even build without IPv4, i.e. !UCLIBC_HAS_IPV4 but only IPv6
|
|
|
- * - it is way too big
|
|
|
- *
|
|
|
- * Both points above are considered bugs, patches/reimplementations welcome.
