* remove dead fileseric2013-11-121-1131/+0
| | | | ok deraadt@
* More shrinkage, a bit for ramdisks but mostly for static binaries:guenther2009-11-181-1/+3
| | | | | | | | | | | | | | | | | - wrap with #ifndef NO_LOG_BAD_DNS_RESPONSES libc code that uses p_class() and p_type() for diagnostics, then add that define to libstub to avoid pulling in res_debug_syms.o - split rcmd() and ruserok() into separate files, as nothing uses both - split readdir_r() to its own file - split syslog_r() from syslog(), as the latter needs localtime(); many binaries no longer need to pull in all the time code after this; switch from usleep() to nanosleep() while we're at it (The profit of analysis of -Wl,-M,--cref output) Chops 888kB from /bin and /sbin on i386 ok deraadt@, miod@
* use RRSIG instead of SIG for DNSSEC. ok djm@jakob2007-10-111-2/+2

* Wrap some functions, labels, and variables in #ifdefs correspondingray2007-05-161-1/+5
| | | | | | | to #ifdefs where they are used. Found by lint by bret dot lambert at gmail. OK deraadt@.
* strlen(3) returns size_t, not int.ray2007-02-181-14/+16
| | | | | | Suggested by itojun@ in response to my getaddrinfo fixes. OK millert@.
* remove size_t and int mixup. same as getaddrinfo.c 1.30 -> 1.31.itojun2007-02-141-5/+2

* zap rcsid.espie2005-08-061-4/+1
| | | | | | | split functions off res_debug.c so that getnetnamadr.c does not pull it all when it's used. okay deraadt@, krw@

* backout gethostent changes for now -- there is fallout, discovered by ottojaredy2005-07-271-10/+22

* In _gethtent() ignore host.h_length if it is set to 0. Previouslymillert2005-07-241-10/+7
| | | | | | we only ignored it if host.h_addrtype was AF_UNSPEC. Set host.h_length to 0 in _gethtbyname2() since that function does not take a length argument. Problem found by jaredy@
* *hostent() fixes:jaredy2005-07-231-22/+13
| | | | | | | | | | | | - Make _gethtent() static - _gethtbyname() is dead code (succeeded by _gethtbyname2), kill it - _gethtent() requires setting the address family field of the file-scope variable `host' to that of the desired type of the entry being searched for. Change the behavior to enforce this if it is not AF_UNSPEC, which will now allow stepping through entries, and set it to specific values everywhere else. help & ok millert
* Make gethostbyaddr() prototype match POSIX. This means len is nowmillert2005-06-081-14/+13

* thread safer libc (note: safer, not safe)marc2003-01-281-31/+29
| | | | | | | | | | Access to the global _res structure replaced by pointers to a per thread instance. If unthreaded the pointer is to the global structure. Also replaced a 64k stack array with malloc-ed memory so threaded aps (with a default 64k stack) have a chance at working. ok deraadt@

* avoid remote buffer overrun on hostbuf[]. From: Joost Pol <joost@pine.nl>itojun2002-06-261-34/+23
| | | | | | | | correct bad practice in the code - it uses two changing variables to manage buffer (buf and buflen). we eliminate buflen and use fixed point (ep) as the ending pointer. this fix is critical.

* always enable IPv6 address in /etc/hosts (via _gethtent()).itojun2000-01-031-3/+2
| | | | | clarify RES_USE_INET6. the use of this bit is not meaningful on openbsd (as we don't have mapped addr support in kernel).
* prevent bogus reverse query for 1.0.0.0.in-addr.arpa.itojun1999-12-111-7/+5
| | | | this occurs by mixing up ::1 as IPv6 auto-tunnel address like ::10.1.1.1.
* fix gethostbyname2(foo, AF_INET6).itojun1999-12-111-1/+9
| | | | | on /etc/hosts lookup, file static variable "hosts" was damaged and prevented lookup of IPv6 hostnames.

| | | | OK'd by deraadt.
* Be consistent about the relaxation of invalid host name checking.niklas1999-06-041-1/+9
| | | | | This allows CNAMEs to PTRs with names including slashes, something not really RFC-compliant but still in general use.
