* avoid remote buffer overrun on hostbuf[]. From: Joost Pol <joost@pine.nl>OPENBSD_2_9millert2002-06-261-34/+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. From: itojun this fix is critical.
* avoid buffer overrun on too-long reply for NIS hostname lookup.itojun2000-07-301-7/+9

* _THREAD_PRIVATE_* macros changedd2000-01-061-2/+2
|
* 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.
* sizeof("string") includes 0 byte; aazubel@tatu.cnba.uba.arderaadt1999-09-031-2/+2

* Ignore SIGs in the answer section for now as we don't use them (yet).jakob1999-07-031-1/+6
| | | | 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.
* Revertion of last change, which was due to emacs' stupid ideaniklas1999-05-301-9/+1
| | | | | of keeping the "*Shell Command Output*" buffer's wd from its creation instead of using the last command's wd!!!!

* Do not provide gethostby.*_r for now, as configure scripts findniklas1999-04-281-4/+4
| | | | | the functions using nm(1), but then no prototypes exist and things break. d@ will contemplate over the issue and resolve it for real later :-)
* Add thread-safety to libc, so that libc_r will build (on i386 at least).d1998-11-201-8/+76
| | | | | | | | | | | | | All POSIX libc api now there (to P1003.1c/D10) (more md stuff is needed for other libc/arch/*) (setlogin is no longer a special syscall) Add -pthread option to gcc (that makes it use -lc_r and -D_POSIX_THREADS). Doc some re-entrant routines Add libc_r to intro(3) dig() uses some libc srcs and an extra -I was needed there. Add more md stuff to libc_r. Update includes for the pthreads api Update libc_r TODO

* yp_prot.h lies -> use yp.h (from yp.x) instead, change lots of structurederaadt1996-04-241-1/+1
| | | | | | | | | accesses to match. change xdr_domainname() and some other functions to take "char **" instead of "char *", as rpcgen intended -- helps programs linking against rpcgen output of yp.x. yp_all() should not free it's return value. split xdryp.c and yplib.c into ~20 files so binaries like "csh" need not link in functions like yp_maplist(). NIS+'s YP emulation code lacks YPPROC_ORDER... attempt to deal nicely.
