From e685e07dfa9de08cd0b671e293b94efe116349fa Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 19 Jul 2000 22:03:58 +0000 Subject: Update. 2000-07-18 Mark Kettenis Update resolver code to BIND 8.2.3-T5B. * resolv/Versions [GLIBC_2.2] (libc): Add __res_init and __res_nclose. [GLIBC_2.2] (libresolv): Add __dn_expand, __ns_samename, __res_mkquery, __res_nsend, __res_query, __res_querydomain and __res_search. * resolv/Banner: BIND-8.2.3-T5B. * resolv/base64.c: Update from BIND 8.2.3-T5B. * resolv/herror.c: Likewise. * resolv/inet_addr.c: Likewise. * resolv/inet_net_ntop.c: Likewise. * resolv/inet_net_pton.c: Likewise. * resolv/inet_neta.c: Likewise. * resolv/inet_ntop.c: Likewise. * resolv/nsap_addr.c: Likewise. * resolv/inet_pton.c: Likewise. Reject a few more more invalid IPv6 addresses (ISC bug #520). * resolv/ns_name.c: Avoid emitting RCS ID in object file. * resolv/ns_parse.c: Likewise. * resolv/ns_netint.c: Likewise. * resolv/ns_samedomain.c: Likewise. * resolv/ns_ttl.c: Likewise. * resolv/ns_print.c: Update from BIND 8.2.3-T5B. Avoid emitting RCS ID in object file. * resolv/res_debug.c: Update from BIND 8.2.3-T5B. * resolv/res_mkquery.c: Likewise. * resolv/res_query.c: Likewise. * resolv/res_init.c: Likewise. (res_setoptions): Mark internal. * resolv/res_send.c: Likewise. [_LIBC]: Fully reinstate the code that avoids the FD_SETSIZE limit by using poll instead. * resolv/res_comp.c: Likewise. [SHLIB_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_2)]: Make dn_expand a weak alias for __dn_expand. * resolv/res_data.c: Likewise. (res_close) [_LIBC]: Don't call res_nclose if RES_INIT isn't set in _res.options. Avoids a potential security risk by avoiding a close (0). [SHLIB_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_2)]: Make res_mkquery, res_query, res_querydomain adn res_search weak aliases for __res_mkquery, __res_query, __res_querydomain and __res_search. * resolv/res_libc.c: (_res): Don't initialize. Fix res_close instead to avoid close(0). (res_init): Always use the static resolver context. [SHLIB_COMPAT (libc, GLIBC_2.0, GLIBC_2_2)]: Make res_init a weak alias for __res_init. * resolv/resolv.h: Update from BIND 8.2.3-T5B. Move definition of RES_SET_H_ERRNO and accompanying comment to... * include/resolv.h: ... here. * resolv/arpa/namser.h: Update from BIND 8.2.3-T5B. * resolv/arpa/nameser_compat.h: Likewise. --- resolv/inet_ntop.c | 27 +++++++++++++++------------ 1 file changed, 15 insertions(+), 12 deletions(-) (limited to 'resolv/inet_ntop.c') diff --git a/resolv/inet_ntop.c b/resolv/inet_ntop.c index a95f684945..f99a69ba75 100644 --- a/resolv/inet_ntop.c +++ b/resolv/inet_ntop.c @@ -1,4 +1,5 @@ -/* Copyright (c) 1996 by Internet Software Consortium. +/* + * Copyright (c) 1996-1999 by Internet Software Consortium. * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above @@ -15,19 +16,20 @@ */ #if defined(LIBC_SCCS) && !defined(lint) -static char rcsid[] = "$Id$"; +static const char rcsid[] = "$BINDId: inet_ntop.c,v 1.8 1999/10/13 16:39:28 vixie Exp $"; #endif /* LIBC_SCCS and not lint */ #include #include #include + #include #include #include -#include + #include #include -#include "../conf/portability.h" +#include #ifdef SPRINTF_CHAR # define SPRINTF(x) strlen(sprintf/**/x) @@ -40,9 +42,9 @@ static char rcsid[] = "$Id$"; * sizeof(int) < 4. sizeof(int) > 4 is fine; all the world's not a VAX. */ -static const char *inet_ntop4 __P((const u_char *src, char *dst, socklen_t size)) +static const char *inet_ntop4 (const u_char *src, char *dst, socklen_t size) internal_function; -static const char *inet_ntop6 __P((const u_char *src, char *dst, socklen_t size)) +static const char *inet_ntop6 (const u_char *src, char *dst, socklen_t size) internal_function; /* char * @@ -74,7 +76,7 @@ inet_ntop(af, src, dst, size) /* const char * * inet_ntop4(src, dst, size) - * format an IPv4 address, more or less like inet_ntoa() + * format an IPv4 address * return: * `dst' (as a const) * notes: @@ -122,7 +124,7 @@ inet_ntop6(src, dst, size) */ char tmp[sizeof "ffff:ffff:ffff:ffff:ffff:ffff:255.255.255.255"], *tp; struct { int base, len; } best, cur; - u_int words[IN6ADDRSZ / INT16SZ]; + u_int words[NS_IN6ADDRSZ / NS_INT16SZ]; int i; /* @@ -131,11 +133,11 @@ inet_ntop6(src, dst, size) * Find the longest run of 0x00's in src[] for :: shorthanding. */ memset(words, '\0', sizeof words); - for (i = 0; i < IN6ADDRSZ; i += 2) + for (i = 0; i < NS_IN6ADDRSZ; i += 2) words[i / 2] = (src[i] << 8) | src[i + 1]; best.base = -1; cur.base = -1; - for (i = 0; i < (IN6ADDRSZ / INT16SZ); i++) { + for (i = 0; i < (NS_IN6ADDRSZ / NS_INT16SZ); i++) { if (words[i] == 0) { if (cur.base == -1) cur.base = i, cur.len = 1; @@ -160,7 +162,7 @@ inet_ntop6(src, dst, size) * Format the result. */ tp = tmp; - for (i = 0; i < (IN6ADDRSZ / INT16SZ); i++) { + for (i = 0; i < (NS_IN6ADDRSZ / NS_INT16SZ); i++) { /* Are we inside the best run of 0x00's? */ if (best.base != -1 && i >= best.base && i < (best.base + best.len)) { @@ -182,7 +184,8 @@ inet_ntop6(src, dst, size) tp += SPRINTF((tp, "%x", words[i])); } /* Was it a trailing run of 0x00's? */ - if (best.base != -1 && (best.base + best.len) == (IN6ADDRSZ / INT16SZ)) + if (best.base != -1 && (best.base + best.len) == + (NS_IN6ADDRSZ / NS_INT16SZ)) *tp++ = ':'; *tp++ = '\0'; -- cgit 1.4.1
