From e4cf5070694529a8779d5e1581567bcfb9307da0 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 2 Dec 1996 04:00:15 +0000 Subject: update from main archive 961201 Mon Dec 2 03:59:38 1996 Ulrich Drepper * grp/initgroups.c: Update and reformat copyright. Use __getgrent_r instead of getgrent. * inet/rcmd.c: Update and reformat copyright. Use __gethostbyname_r instead of gethostbyname. * inet/rexec.c: Likewise. * intl/finddomain.c: Correct comment about CEN sponsor and revision. * locale/findlocale.c: Likewise. * intl/l10nflist.c: Correct handling of CEN sponsor and revision. * locale/Makefile (CPPFLAGS): Add definition of LOCALEDIR. * locale/setlocale.c (setlocale): Correctly split value of LOCALE_PATH. * locale/programs/localedef.c: Use LOCALEDIR not LOCALE_PATH to find output directory. * nss/getXXbyYY.c [NEED_H_ERRNO]: Before enlarging buffer test h_errno_tmp variable. Save error value from being changed during `free' call. * nss/getXXent.c: Likewise. * nss/nss_files/files-XXX.c: Set h_errno variable to NETDB_INTERNAL before returning ERANGE error. * posix/glob.c: Use getlogin_r and getpwnam_r function when available or in GNU libc. * pwd/getpw.c: Use getpwuid_r instead of getpwuid. * sunrpc/clnt_gen.c: Use gethostbyname_r and getprotobyname_r. * sunrpc/clnt_simp.c: Likewise. * sunrpc/getrpcport.c: Likewise. * sysdeps/unix/sysv/linux/gethostid.c: Likewise. * posix/getconf.c: Treat _SC_UNIT_MAX and _SC_ULONG_MAX separately since the value might be outsode the range of the `long int'. Print string `undefined' when a value is undefined. * stdlib/l64a.c: Return correct pointer. Patch by NIIBE Yutaka . * string/Makefile (routines): Add argz-addsep. * string/argz-addsep.c: New file. * string/argz.h: Add prototypes for argz_add_sep. * string/argz-ctsep.c: Prevent memory leak. * string/strcoll.c: Correct typo in comment. Sat Nov 30 02:53:59 1996 Ulrich Drepper * sysdeps/unix/sysv/linux/sys/serial.h: Removed again. The file is not general enough to be part of the libc. * sysdeps/unix/sysv/linux/Dist: Remove sys/serial.h. * sysdeps/unix/sysv/linux/Makefile: Don't install sys/serial.h. Thu Nov 28 20:04:41 1996 Andreas Schwab * login/Makefile: Fix typo. * nss/Makefile (generated): Filter out db-alias.c. Thu Nov 28 14:44:01 1996 Andreas Schwab * time/Makefile (echo-zonenames): Don't depend on non-existing target `zonenames'. Thu Nov 28 12:34:05 1996 Andreas Schwab * link.h: New file. * nss/nsswitch.c: Use it. * printf.h: Fix file name. * stdlib/strfmon.c: Use it. --- inet/rexec.c | 27 +++++++++++++++++++++------ 1 file changed, 21 insertions(+), 6 deletions(-) (limited to 'inet/rexec.c') diff --git a/inet/rexec.c b/inet/rexec.c index f4772475fd..d91949de3c 100644 --- a/inet/rexec.c +++ b/inet/rexec.c @@ -40,6 +40,7 @@ static char sccsid[] = "@(#)rexec.c 8.1 (Berkeley) 6/4/93"; #include +#include #include #include #include @@ -56,16 +57,30 @@ rexec(ahost, rport, name, pass, cmd, fd2p) int *fd2p; { struct sockaddr_in sin, sin2, from; - struct hostent *hp; + struct hostent hostbuf, *hp; + size_t hstbuflen; + char *hsttmpbuf; u_short port; int s, timo = 1, s3; char c; + int herr; + + hstbuflen = 1024; + hsttmpbuf = __alloca (hstbuflen); + while (__gethostbyname_r (*ahost, &hostbuf, hsttmpbuf, hstbuflen, + &hp, &herr) < 0) + if (herr != NETDB_INTERNAL || errno != ERANGE) + { + herror(*ahost); + return -1; + } + else + { + /* Enlarge the buffer. */ + hstbuflen *= 2; + hsttmpbuf = __alloca (hstbuflen); + } - hp = gethostbyname(*ahost); - if (hp == 0) { - herror(*ahost); - return (-1); - } *ahost = hp->h_name; ruserpass(hp->h_name, &name, &pass); retry: -- cgit v1.2.3
