Brad House	b5235416fc	cast-align warnings are false for struct sockaddr, silence Create a macro to silence false cast-align warnings when casting struct sockaddr * to struct sockaddr_in * and struct sockaddr_in6 *. Fix By: Brad House (@bradh352)	5 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
Dionna Glaze	e47cfb44b8	Simple changes to appease stricter compilers. ares_process.c uses htonl, which needs <arpa/inet.h> included. ares_getnameinfo.c uses a dynamically selected format string for sprintf, which -Wformat-literal doesn't like. Usually one would use inttypes.h and a format string "%" PRIu32, but C99 is too new for some supported platforms.	8 years ago
David Drysdale	d311c47920	Explicitly clear struct servent before use On a build where MSAN has been manually set up (which involves using an MSAN-instrumented version of the standard C++ library, see https://github.com/google/sanitizers/wiki/MemorySanitizerLibcxxHowTo) there's a warning about use of uninitialized memory here. It might be a false positive, but the fix is trivial so include it.	9 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	d493e9b17c	api: Add option to expose some internal functions Purely for testing, add --enable-expose-statics option to configure which converts some static internal functions to be externally visible.	9 years ago
David Drysdale	87ff25049c	Mark unhittable lines Add comments for the benefit of the lcov tool, marking lines that cannot be hit. Typically these are fall-back protection arms that are already covered by earlier checks, and so it's not worth taking out the unhittable code (in case someone changes the code between the two places in future).	9 years ago
David Drysdale	de04975c48	ares_striendstr: fix so non-NULL return can happen This looks to have been broken since it was first introduced in 2005 in commit `aba0b775ea` ("Added ares_getnameinfo which mimics the getnameinfo API")	9 years ago
