2014-03-14prefix structure names to avoid ambiguity and possible collisions whenEric Faurot
the API gets public. ok deraadt@
2014-03-03fix support for HOSTALIASES.Eric Faurot
reported by tedu@ ok tedu@ deraadt@
2014-02-26need more #include files for resolv.h, for the non-YP case, which happensTheo de Raadt
on the install media... ok eric
2014-02-26Do not restrict chars in dname during label expansion, but validate resultingEric Faurot
hostnames before returning them to the caller. ok deraadt@
2014-02-24make res_search() report NO_DATA instead of HOST_NOT_FOUND in some cases.Eric Faurot
issue reported by matthieu@ ok matthieu@ deraadt@
2014-02-17Better search strategy for getaddrinfo. The address family loop mustEric Faurot
be done "inside" the search domain loop, not the other way round.
2014-02-17report extra PTR records as aliasesEric Faurot
2014-01-15Initialise _res.nsaddr_list in res_init(), fixing some programs which dependStuart Henderson
on bind resolver internals. Note, the list will not be updated if resolv.conf is changed while the program runs unless the caller resets the RES_INIT flag. Approach suggested by otto@, original diff from Kapetanakis Giannis, fix suggested by tedu@ and dug up again by Riccardo Mottola. Looks ok to eric@.

2013-06-01Move search domain iteration code in res_search_async.c where it belongs.Eric Faurot
2013-06-01Make hostaliases work for gethostbyname() and getaddrinfo() whenEric Faurot
looking into /etc/hosts. Remove the alias check from the search domain iteration. Instead, take a shortcut to res_query_async_ctx() in res_search_async_ctx().
2013-06-01Update asr_hostaliases() to make all necessary checks in the function.Eric Faurot
Explicitely check for issetguid() before calling getenv(). Also make asr_hostalias() callable from other parts of asr too.
2013-06-01iterating over the ns list only matters for res_send_async.c, so moveEric Faurot
things around.
2013-05-29use paramaters instead of static storage in _gethostbyname()Eric Faurot
2013-05-27Add minimal support for _res setup and update.Eric Faurot
Change res_init() to initialize the _res structure on first call, and udpate the global async context if changes were made by the user. All resolver functions now call res_init() internally. fixes issue spotted by otto@
2013-04-30various small fixes;Jason McIntyre
2013-04-30Do not take external buffers for storing DNS responses in the internalEric Faurot
async API. That is actually useless and it makes the code more complicated. The required buffers are always allocated when needed.

2013-04-08Do not fail if the user buffer is too short to hold the packet: fill it upEric Faurot
