Brad House	3a46457deb	replace all usages of inet_addr() with ares_inet_pton() which is more proper (#312 ) Replace usage of inet_addr() with ares_inet_pton() which is more appropriate and fixes issues with legitimate addresses like 255.255.255.0. IPv6 already used this. Fixes #309 Fix By: Brad House (@bradh352)	5 years ago
tjwalton	287bde0558	ares_gethostbyname: Return ENODATA if no valid A or AAAA record found (#304 ) ares_gethostbyname() was returning ESUCCESS when no A or AAAA record was found but a CNAME pointing nowhere was present. ENODATA should be returned instead, however the hosts pointer will still be present to provide the alias list. * Return ENODATA if no valid A or AAAA record found * Fix and update test ParseAReplyNoData. * Add test for new ENODATA behaviour in ares_gethostbyname. Fixes Bug #303 Fix By: @tjwalton	5 years ago
Brad House	9f1fdbf5dd	Fix c89 compilation support broken by .onion rejection changes Move .onion check lower after all variables have been declared. Bug: #246	6 years ago
Ben Noordhuis	955df983d7	Report ARES_ENOTFOUND for .onion domain names as per RFC7686. (#228 ) Quoting RFC 7686: Name Resolution APIs and Libraries (...) MUST either respond to requests for .onion names by resolving them according to [tor-rendezvous] or by responding with NXDOMAIN. A legacy client may inadvertently attempt to resolve a .onion name through the DNS. This causes a disclosure that the client is attempting to use Tor to reach a specific service. Malicious resolvers could be engineered to capture and record such leaks, which might have very adverse consequences for the well-being of the user. Bug: #196 Fix By: Ben Noordhuis @bnoordhuis	6 years ago
Gergely Nagy	2a9e231396	Force using the ANSI versions of WinAPI functions (#142 ) When compiling c-ares with a build system that defines UNICODE, bad versions of WinAPI functions are used causing failures or even crashes. When windows.h is included in MBCS mode (like in the default build system), the ..A versions are the same as using the one without any suffix.	7 years ago
David Drysdale	f1bcfa1122	api: Allow injection of user-specified malloc/free functions Add a new ares_library_init_mem() initialization function for the library which allows the library user to specify their own malloc, realloc & free equivalents for use library-wide. Store these function pointers in library-wide global variables, defaulting to libc's malloc(), realloc() and free(). Change all calls to malloc, realloc and free to use the function pointer instead. Also ensure that ares_strdup() is always available (even if the local environment includes strdup(3)), and change the library code to always use it. Convert calls to calloc() to use ares_malloc() + memset	9 years ago
David Drysdale	52c9bc57bd	ares_gethostbyname: don't leak valid-but-empty hostent If an AF_UNSPEC query gets a valid response to its AAAA query, but which has no IPv6 addresses in it, then the code chains on to a A record query. However, the hostent from the AAAA response was being leaked along the way (because it gets replaced before the follow-on end_hquery() invocation).	9 years ago
Jakub Hrozek	c1fe47f6d9	host_callback: Fall back to AF_INET on searching with AF_UNSPEC Previously, when an ares_gethostbyname() searched with AF_UNSPEC and the first AF_INET6 call only returned CNAMEs, the host_callback never retried AF_INET. This patch makes sure than on ARES_SUCCESS, the result of AF_INET6 is taken as authoritative only if the result contains some addresses.	10 years ago
Daniel Stenberg	cf7ad9758d	ares_inet_pton/ntop: cleanup Make sure that the symbols are always exported and present in c-ares. Make the headers prefixed with 'ares'. Removed the inet_ntop.h version as it no longer features any content.	12 years ago

Yang Tse	a1035276c1	Header inclusion clean-up Remove header inclusions already done in setup_once.h	12 years ago
Yang Tse	14eb79f660	warnings: fix some 'conversion may lose significant bits' compiler warnings	13 years ago

Jakub Hrozek	159b82c056	Revert "Only fall back to AF_INET searches when looking for AF_UNSPEC addresses" This reverts commit `b5823d6570`. This patch was not reviewed properly before pushing	14 years ago

Steinar H. Gunderson	cef560e871	Support lookup of IPv4 literals in ares_gethostbyname(), even when the address family is set to AF_INET6.	15 years ago
Yang Tse	737707bf4b	fix compiler warning: implicit conversion shortens 64-bit value into a 32-bit value	16 years ago
Phil Blundell	3f7fc80ab5	* February 3 2009 (Phil Blundell) - If the server returns garbage or nothing at all in response to an AAAA query, go on and ask for A records anyway.	16 years ago
Daniel Stenberg	1ce8e6583e	- ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving either AF_INET6 or AF_INET. It works by accepting any of the looksups in the hosts file, and it resolves the AAAA field with a fallback to A.	16 years ago
Gisle Vanem	f94afa4fdc	Constified some arguments in local functions.	16 years ago
Yang Tse	aa1534eb20	In preparation for the upcomming IPv6 nameservers patch, the internal ares_addr union is now changed into an internal struct which also holds the address family.	16 years ago
Daniel Stenberg	acf5ca090a	use unsigned short better intead of mixing with ints to prevent compiler warnings	16 years ago
Daniel Stenberg	8a6b51d560	- Brad Spencer brought the new function ares_gethostbyname_file() which simply resolves a host name from the given file, using the regular hosts syntax.	16 years ago

Yang Tse	f2582d6949	include header file only when available	16 years ago
Yang Tse	2cb5cbba34	move inclusion of ares_private.h last	16 years ago
Daniel Stenberg	93e7573628	- Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and the target host has only A records, it automatically falls back to an AF_INET lookup and gives you the A results. However, if the target host has a CNAME record, this behaviour is defeated since the original query does return some data even though ares_parse_aaa_reply() doesn't consider it relevant. Here's a small patch to make it behave the same with and without the CNAME.	17 years ago
Daniel Stenberg	7829b79768	check for strings.h in configure and use it for the strcasecmp() proto	17 years ago

Steinar H. Gunderson	d9dd239771	When looking up in DNS and then in the hosts file, return the error code from DNS if both fail, instead of returning the error code from the hosts file, as today. Patch from the Google tree.	17 years ago
Steinar H. Gunderson	b4bdb6d4d7	Return TTL data from ares_parse_{a,aaaa}_reply, if the user is so inclined. Patch from the Google tree.	17 years ago
Daniel Stenberg	338d59bd0b	Fixed the problem where next_lookup would use 'status' uninitialized. Now it gets passed the initial value as an argument.	17 years ago

Steinar H. Gunderson	50ba81cd23	Make the query callbacks return the number of timeouts that happened during the execution of a query, and update documentation accordingly. (Patch from the Google tree.)	17 years ago
