Use getnameinfo to extract port number string. (remote_addr, remote_port, local_addr, local_port): Make buffers bigger. (doit): Use sockaddr_storage for local address. Get rid of all settings of non_privileged, since it's never used. Don't copy remote address to local variable. Use getnameinfo instead of inet_ntoa to format addresses and port numbers for environment variables. Create secondary channel socket in same address family as primary channel socket; use rresvport_af if available. * kcmd.c (setup_secondary_channel): Use select to time out after 10 minutes, or notice the primary channel being closed or receiving data while we wait for the secondary one to be set up. * compat_recv.c: New file, moved from lib/krb5util. * Makefile.in (SRCS, OBJS): Include it.

Actually save errno value when preparing error text to print. Free address info before returning. 2002-03-08 Ken Raeburn <raeburn@mit.edu> * kcmd.c: Include fake-addrinfo.c once again. (kcmd_connect): Use getaddrinfo instead of gethostbyname, but only get AF_INET addresses for now. Add new argument, pointer to where to store local socket address used; call getsockname to fill it in. Always call getport with the address family from the current address. Retry connection to the same remote address if the error returned was EADDRINUSE; that applies to the local address. (setup_socket): New function. (getport): Use setup_socket. When selecting an address family to use, fall through in the last case instead of calling getport recursively. (kcmd, k4cmd): Don't call getsockname, let kcmd_connect do it. Delete unused variables. Don't set *fd2p before calling setup_secondary_channel. (setup_secondary_channel): No cleanup is needed, just return error indications rather than branching to end of function. If fd2p is non-null, initialize the pointed-to value to -1. * rcp.M: Document -f and -t options as internal use only. 2002-03-07 Ken Raeburn <raeburn@mit.edu> * kcmd.c: Revert 2002-02-10 changes except those related to getport.

Should get cleaned up at some later point to actually I_PUSH "pckt" or equivalent and do translation between STREAMS and BSD style packet mode. 2001-05-10 Tom Yu <tlyu@mit.edu> * defines.h: Fix k4cmd prototype to match kcmd.c. * kcmd.c (k4cmd): Fix to not use a narrow type. * krlogin.c: Fix prototypes so they don't include narrow types. 2001-04-26 Ken Raeburn <raeburn@mit.edu> * configure.in: Don't use KRB5_CHECK_PROTOS. 2001-04-02 Tom Yu <tlyu@mit.edu> * login.M: Don't include "= 0" as part of the "accept_passwd" config option.

[patch from David MacKenzie krb5-appl/913] 2001-01-23 Tom Yu <tlyu@mit.edu> * forward.c (rd_and_store_for_creds): Overwrite any existing value of the KRB5CCNAME environment variable. 2001-01-16 Ken Raeburn <raeburn@mit.edu> * krcp.c (error): Always declare with ellipsis. 2001-01-13 Sam Hartman <hartmans@mit.edu> * configure.in: Force SunOS to not use termios. 2001-01-12 Sam Hartman <hartmans@mit.edu> * krlogin.c: Previously, we only used TIOCGLTC on systems with termios. This is sort of silly since its a BSD 4.[23] IOCTL. We then go out of our way not to use it on IRIX, Solaris or HPUX. I think all this comes about because you really want to use BSD IOCTLS on Sunos rather than termios. I propose to do that and never use BSD IOCTLs on Sunos. 2000-12-15 Ken Raeburn <raeburn@mit.edu> * krlogin.c (main): Add new "-4" option, to use krb4 authentication only; useful for testing. * rlogin.M: Updated. 2000-12-06 Ken Raeburn <raeburn@mit.edu> * krlogind.c (doit): Cast first argument to pty_make_sane_hostname to sockaddr pointer. * krshd.c (doit): Likewise. 2000-11-01 Ezra Peisach <epeisach@mit.edu> * configure.in: Update to autoconf 2 macro names: AC_FORK->AC_FUNC_VFORK, AC_CONST->AC_C_CONST, AC_HEADER_CHECK -> AC_CHECK_HEADER.

Handle case where we have gotten v5 creds via password being entered and don't crash in that case, since previous code was assuming that v5 creds were always being provided. Adapted from patch by Bob Basch. 2000-06-10 Ken Raeburn <raeburn@mit.edu> * krcp.c (main): Fix logic again, this time in the "success" case. If there's a problem retrieving the new-protocol subkey, print a message and exit, don't fall back. * krsh.c (main): Ditto; don't look at enctype to try to guess protocol version. Delete unused variable "similar". 2000-06-09 Ken Raeburn <raeburn@mit.edu> * krlogin.c (main): Rework fallback logic. Fall back to k4cmd unless encryption and the new protocol were both requested. * krsh.c (main): Rework fallback logic. Fall back to k4cmd if new protocol wasn't requested. * krcp.c (main): Revert setting of AP_OPTS_MUTUAL_REQUIRED unconditionally, which was added by mistake with last set of patches. If kcmd fails and the new protocol is requested, don't fall back to v4. 2000-05-31 Ken Raeburn <raeburn@mit.edu> * Makefile.in (kcmd.o, krcp.o, krlogin.o, krlogind.o, krsh.o, krshd.o): Depend on defines.h. * krlogind.c: Include defines.h. * krcp.c: Ditto. * defines.h (enum kcmd_proto): New type.

(doit): Cast pointer argument to getsockname. (recvauth): Do krb4 stuff only if KRB5_KRB4_COMPAT is defined; otherwise, skip it and call krb5_recvauth. * kcmd.c (do_lencheck): Define even if !KRB5_KRB4_COMPAT. 1999-07-26 Ken Raeburn <raeburn@mit.edu> * login.c (main): Fix typo in computing strncpy length for shell name. Sat Jul 24 08:50:39 1999 Ezra Peisach <epeisach@mit.edu> * Makefile.in (kshd): Add $(LOGINLIBS). 1999-07-09 Ken Raeburn <raeburn@mit.edu> AIX 4.3.2 changes based on bug report from Joshua Lackey, lackeyj@austin.ibm.com: * configure.in: Check for rmufile function. * login.c (update_ref_count) [! HAVE_RMUFILE]: Call putgroupattr with SEC_DELETE before SEC_COMMIT; don't call rmufile. Fri Mar 12 19:01:35 1999 Tom Yu <tlyu@mit.edu> * Makefile.in (kshd): Add $(LOGINLIBS). Mon Mar 8 19:21:23 1999 Tom Yu <tlyu@mit.edu> * kshd.M: Resync manpage. * krshd.c: Rework hostname logging. Wed Feb 24 20:05:40 1999 Tom Yu <tlyu@mit.edu> * klogind.M: Resync manpage. * krlogind.c: Rework flags for hostname logging. Mon Feb 22 22:26:32 1999 Tom Yu <tlyu@mit.edu> * kcmd.c (kcmd): Fix up to not call sname_to_principal until after all the addresses in hp have been iterated through to avoid smashing. [krb5-appl/516] * kcmd.c (k4cmd): Move call to krb_realmofhost() to avoid smashing hp. Wed Feb 17 17:24:11 1999 Tom Yu <tlyu@mit.edu> * klogind.M: Document things a little better, including new options controlling hostname manipulation. * krlogind.c: Make use of pty_make_sane_hostname() for purposes of manipulating hostname to pass to login. Also unconditionally syslog IP address and full hostname of remote host. Add command line options to control such behavior. * configure.in: Add arpa/nameser.h to CHECK_HEADERS. Wed Jan 20 21:42:41 1999 Tom Yu <tlyu@mit.edu> * login.c (main): Call setluid(). * krshd.c (doit): Call setluid(). * configure.in: Check for setluid() rather than main() in libsecurity. 1998-11-28 Sam Hartman <hartmans@mesas.com> * krshd.c krsh.c: Use RCMD_BUFSIZ not RSH_BUFSIZE [krb5-appl/678] * kcmd.c: Move RCMD_BUFSIZ into defines.h 1998-11-16 Geoffrey King <gjking@mit.edu> * login.c (login_get_kconf): Also test whether *kconf_val is null rather than just kconf_val before passing *kconf_val to conf_affirmative (where strcasecmp will choke on it if it is in fact null). 1998-11-13 Theodore Ts'o <tytso@rsts-11.mit.edu> * Makefile.in: Set the myfulldir and mydir variables (which are relative to buildtop and thisconfigdir, respectively.) 1998-10-24 Marc Horowitz <marc@mit.edu> * login.c: update to new get_creds API * krlogin.c (main, oob, server_message, control), krlogind.c (sendoob, protocol, recvauth): If the enctype is not similar to DES, use an inband signalling protocol instead of MSG_OOB data to indicate status changes. * kcmd.c (rcmd_stream_init_krb5, v5_des_read, v5_des_write): update to new crypto API. Add ivec chaining to encryption when the enctype is not similar to DES as part of the new protocol. 1998-10-06 Theodore Ts'o <tytso@rsts-11.mit.edu> * krshd.c (doit): Apply ghudson's patch so that rshd passes the port numbers for the local and foreign addresses so that the V4 encrypted RCP will work correctly. [krb5-appl/638] * v4rcp.c (answer_auth): Apply ghudson's patch so that if KRB5LOCALPORT and KRB5REMOTEPORT are set, use them to set the foreign and local ports so that encrypted rcp for the same machine. [krb5-appl/638] Tue Aug 18 16:48:02 1998 Tom Yu <tlyu@mit.edu> * krlogin.c: Add <sys/filio.h> for FIONREAD. Sat Aug 15 00:01:15 1998 Geoffrey King <gjking@mit.edu> * krcp.c (error): Don't call rcmd_stream_write if iamremote is not set, because it expects a valid file descriptor [krb5-appl/359]. Also, remove mistakenly duplicated comment above the function. Mon Jul 27 00:06:20 1998 Geoffrey King <gjking@mit.edu> * krlogin.c (main): Apply ghudson's patch so that rlogin -a no longer dumps core. [krb5-appl/612] Sun Jul 26 23:46:36 1998 Sam Hartman <hartmans@utwig.mesas.com> * login.c (main): Allow krb524 conversion for forwarded tickets (try_convert524): Don't check to see if we have tickets here; caller does that and actually gets it right. 1998-05-26 Theodore Ts'o <tytso@rsts-11.mit.edu> * login.c (dolastlog): BSD 4.4 systems don't have lastlog.h, but still define struct lastlog somewhere. Included from Dima Ruban's FreeBSD patches. * krlogin.c: Include sys/ioctl_compat.h if it is present (instead of just for 386BSD). * loginpaths.h (LPATH): If the OS provides _PATH_DEFPATH, use it to define LPATH and RPATH. * login.c: #include paths.h if present, and use it to set the pathnames for certain common files. * configure.in (withval): Check for <sys/ioctl_compat.h> and <paths.h> Sat May 16 16:07:42 1998 Tom Yu <tlyu@mit.edu> * login.c: Replace strcpy with strncpy in places. Add nul termination to some existing invocations of strncpy. 1998-05-06 Theodore Ts'o <tytso@rsts-11.mit.edu> * configure.in: Add a check for the header file krb4-proto.h. Replace file existence tests for /etc/environment and /etc/TIMEZONE with K5_AC_CHECK_FILES. * login.c (main): * krshd.c (main): * krlogind.c (main): POSIX states that getopt returns -1 when it is done parsing options, not EOF. Sat Feb 28 10:44:46 1998 Theodore Ts'o <tytso@rsts-11.mit.edu> * configure.in: Clean up configure script. Check $cross_compiling instead of (no longer correct) cache variable; remove obsolete AC_C_CROSS. Use AC_CHECK_FUNCS instead of individual AC_FUNC_CHECK calls for speed. Change checks for strsave and utimes to use AC_CHECK_FUNCS * krcp.c, v4rcp.c: Change usages of HAS_STRSAVE and HAS_UTIMES to HAVE_*. Tue Feb 24 14:52:33 1998 Tom Yu <tlyu@mit.edu> * kcmd.c: Integrate ghudson's changes for client-side krb4 compatibility. [krb5-appl/483] * krcp.c: Integrate ghudson's changes for client-side krb4 compatibility. [krb5-appl/483] * krlogin.c: Integrate ghudson's changes for client-side krb4 compatibility. [krb5-appl/483] * krlogind.c: Integrate ghudson's changes for client-side krb4 compatibility. [krb5-appl/483] * krsh.c: Integrate ghudson's changes for client-side krb4 compatibility. [krb5-appl/483] * krshd.c: Integrate ghudson's changes for client-side krb4 compatibility. [krb5-appl/483] Sun Feb 22 19:16:12 1998 Tom Yu <tlyu@mit.edu> * v4rcp.c: Punt nastiness to redefine setreuid, as we don't use it. * krcp.c: Use krb5_seteuid(). [krb5-libs/505] Fix up inclusions to use <> rather than "". Wed Feb 18 15:26:52 1998 Tom Yu <tlyu@mit.edu> * Makefile.in: Remove trailing slash from thisconfigdir. Fix up BUILDTOP for new conventions. Mon Feb 2 17:02:29 1998 Theodore Ts'o <tytso@rsts-11.mit.edu> * Makefile.in: Define BUILDTOP and thisconfigdir in the Makefile Tue Jan 20 21:42:06 1998 Tom Yu <tlyu@mit.edu> * krlogind.c (protocol): Declare pibuf and fibuf as being BUFSIZ bytes long, rather than 1024. Fixes an Irix bug. [krb5-appl/527] Fri Dec 19 18:19:42 1997 Dan Winship <danw@mit.edu> * login.c (try_afscall): try_afscall doesn't work / isn't needed on systems without SIGSYS Thu Dec 11 23:20:20 1997 Tom Yu <tlyu@mit.edu> * krlogind.c: * krshd.c: * login.c: * v4rcp.c: Don't include netdb.h or sys/socket.h if krb.h is included; this works around an Ultrix bug where those headers aren't protected against multiple inclusion. Thu Nov 20 16:42:54 1997 Tom Yu <tlyu@mit.edu> * krlogind.c (recvauth): Fix args in call to rd_and_store_for_creds. [krb5-appl/502] Mon Nov 17 20:55:31 1997 Tom Yu <tlyu@mit.edu> * krshd.c: Don't set checksum_ignored to 1 if checksum_required is 0; also, if a krb5 client passes in a checksum, check it regardless of whether checksum_required is true. [krb5-appl/500] Wed Nov 12 19:03:02 1997 Tom Yu <tlyu@mit.edu> * forward.c (rd_and_store_for_creds): Don't do the chown. Avoids a security hole. [krb5-appl/494] * krshd.c (recvauth): chown the ccache explicitly, as rd_and_store_for_creds no longer does so. [krb5-appl/494] Thu Nov 6 22:04:26 1997 Theodore Y. Ts'o <tytso@mit.edu> * v4rcp.c: Use error_message(errno) instead of using sys_errlist[errno]. This avoids the hair of deciding whether or not we need to declare sys_errlist or use strerror(), etc., since com_err has all of that complexity anyway. Also fixed lots of -Wall nits. Mon Nov 3 15:25:48 1997 Tom Yu <tlyu@mit.edu> * krlogind.c (doit): Fix up potential buffer overrun. [krb5-appl/488] * krlogin.c (main): Fix up potential buffer overrun. * krcp.c (hosteq): Fix up potential buffer overrun. Tue Oct 7 18:01:15 1997 Theodore Y. Ts'o <tytso@mit.edu> * v4rcp.M: Removed useless .so to a non-existent macro file. Tue Sep 2 19:44:21 1997 Tom Yu <tlyu@mit.edu> * krlogind.c (main): Changes to allow for standalone daemon operation. Use the "-f" flag to enable. This automagically figures out which port to bind to if you don't specify it. Mon Jun 30 13:21:34 1997 Kevin L Mitchell <klmitch@mit.edu> * login.c (dofork): Solaris 2.4 puts killpg in the bsd compatibility libraries. Autoconf correctly determined that it wasn't available, but it wasn't conditionalized out. Added the conditional, using kill(-child, SIGHUP) as a replacement, as suggested by tlyu Thu Jun 5 15:56:54 1997 Theodore Ts'o <tytso@rsts-11.mit.edu> * login.c: Always use the new tty line discpline. [krb5-appl/428] * login.c: If a hangup signal is received, pass it onto the child. [krb5-appl/432] Fri Mar 28 01:05:27 1997 Theodore Y. Ts'o <tytso@mit.edu> * login.c (NO_MOTD): If we're on an SGI machine, don't do the MOTD or MAILCHECK thing, since it's done by /etc/cshrc magic. (SGI's don't define __SVR4, even though it's SVR4 derived). [krb5-appl/158] * krlogin.c (try_normal): When falling back to the normal rlogin, clear the signal mask, so that the child rlogin handles SIGUSR1 (which is used for window size changes) correctly. [krb5-appl/335] Tue Mar 18 12:34:03 1997 Sam Hartman <hartmans@luminous.MIT.EDU> [326] * login.c(doit): Preserve terminal even without -p. Thu Feb 27 10:58:07 1997 Sam Hartman <hartmans@luminous.MIT.EDU> * krshd.c: Allow user to login with / as home directory if homedir not found. [167] Sat Feb 22 00:54:06 1997 Sam Hartman <hartmans@luminous.MIT.EDU> * krlogin.c (mode): Clean up Posix terminal handling for NetBSD. Tue Feb 18 18:03:55 1997 Richard Basch <basch@lehman.com> * krcp.c: Replace krb5_xfree with krb5_free_data_contents * kcmd.c krlogind.c krshd.c: Use free instead of internal krb5_xfree * krlogin.c: Fixed 8bit character flow under Solaris * kcmd.c: getport() lets the OS pick the port rather than scanning * krshd.c: Don't bother to set lport before calling getport(&lport) Sat Dec 28 21:06:43 1996 Sam Hartman <hartmans@luminous.MIT.EDU> * login.c: Force environment variables like HOME to be set even if -p given. Wed Feb 5 20:56:03 1997 Tom Yu <tlyu@mit.edu> * Makefile.in: * configure.in: Update to new program build procedure. Tue Dec 24 16:08:41 1996 Tom Yu <tlyu@mit.edu> * configure.in: Fix up "test $ac_cv_c_cross" to deal with autoconf-2.12, since that variable can be set to a null string. Fri Dec 6 00:53:08 1996 Theodore Y. Ts'o <tytso@mit.edu> * v4rcp.c: Extend the platform-specific braindamage so that FreeBSD works. This whole file is eventually going to need serious rototilling to make it even vaguely correct. [PR #284] Fri Dec 6 00:02:25 1996 Tom Yu <tlyu@mit.edu> * loginpaths.h: Add catch-all entries for LPATH and RPATH in case we run across something that we haven't hardcoded paths for yet. [267] Thu Dec 5 21:58:28 1996 Tom Yu <tlyu@mit.edu> * login.M: v5srvtab -> krb5.keytab [279] Sun Nov 24 23:35:22 1996 Ezra Peisach <epeisach@mit.edu> * login.c (try_afscall): Change to take pointer to function instead of only calling setpag(). [krb5-appl/190] Fri Nov 22 15:46:46 1996 unknown <bjaspan@mit.edu> * kcmd.c (kcmd): use sizeof instead of h_length to determine number of bytes of addr to copy from DNS response [krb5-misc/211] Thu Nov 14 14:30:28 1996 Barry Jaspan <bjaspan@mit.edu> * krcp.c: don't print our own error message if kcmd returns -1 (it always printed something in that case, and error_message(-1) prints a mess [krb5-appl/70] Mon Nov 11 23:38:05 1996 Mark Eichin <eichin@cygnus.com> * krshd "plumbing" fixes Tue Jun 25 19:51:07 1996 Mark Eichin <eichin@cygnus.com> * krshd.c (doit): ignore SIGPIPE in the child, check the return status of write instead. Added comments labelling the various file descriptors. Cleaned up formatting somewhat. Check for failure of write to child stdin pipe, and stop reading. Check for output from child before checking for input from net, to reduce potential for missed output. (cleanup): moved before doit, to eliminate need for declaration. Added an argument, to allow reporting of what signal kshd died on, and report that the daemon terminated, not the shell. Thu Jun 20 18:54:04 1996 Mark Eichin <eichin@cygnus.com> * krshd.c: fix global-change typo in !KERBEROS branch. Mon Nov 11 15:00:25 1996 Mark Eichin <eichin@cygnus.com> * Makefile.in, configure.in, krshd.c, v4rcp.M, v4rcp.c: added kerberos V4 rcp -x support from Cygnus tree. * Makefile.in, configure.in: added support for not building v4rcp if --without-krb4 is used. Sun Aug 11 17:30:39 1996 Chris Provenzano <proven@cygnus.com> * v4rcp.c : #include <fcntl.h> for O_* flags. Mon Jul 8 13:44:39 1996 Mark Eichin <eichin@cygnus.com> * v4rcp.c (getdtablesize): eliminate local copy. (kstream_write): eliminate srandom/random in favor of krb5_random_confounder. Add sys/socket.h to includes (v4 had it internal to krb.h.) (utimes): clone utimes-emulation from v5 krcp.c (should perhaps be changed to use AC_REPLACE_FUNC...) Declare getenv. Sat Jul 6 16:39:28 1996 Mark W. Eichin <eichin@kitten.gen.ma.us> * v4rcp.c (answer_auth): use inet_aton only if we have it; otherwise fake it with inet_addr. * configure.in: check_func for inet_aton. Tue Jul 2 19:37:52 1996 Mark Eichin <eichin@cygnus.com> * krshd.c (envinit): clarified initializations, labeled all slot reservations (SAVEENVPAD, KRBPAD, ADDRPAD are lists of zeroes.) Move TZ to always be slot 5, even on the cray. Added space for the local and remote addresses. (doit): add a getsockname to save the correct local address for the child. Set KRB5LOCALADDR and KRB5REMOTEADDR to literal IP addresses since the child is on the wrong side of a pipe and can't recover them directly. * v4rcp.c (kstream): add common "writelen" field for the length of inbuf and outbuf. (kstream_create_rcp_from_fd): initialze new fields. (kstream_write): grab a big enough buffer (since this is called with chunks that may correspond to the *filesystem* blocksize, which is usually larger than BUFSIZ.) Also skip the first four bytes of outbuf so that the encryption is done on an 8 byte boundary (if malloc is correctly aligned, malloc+8 should also be.) (answer_auth): don't try to getpeername or getsockname, since we're run under a pipe; just use KRB5LOCALADDR and KRB5REMOTEADDR which are now provided by kshd (and fail if they are not present.) This is safe because if they're wrong, it just means that the mutual authentication will fail. Thu Jun 27 23:32:41 1996 Mark Eichin <eichin@cygnus.com> * Makefile.in (all, clean, install, v4rcp): add v4rcp installation and build rules. * krshd.c: if we got a V4 connection and the command is rcp, use the v4rcp backend to handle encryption. * v4rcp.c: based on Cygnus CNS V4 rcp, stripped down to eliminate user commands (and truncated usage message.) Includes a fake subset of the kstream interface that only handles "rcp -x" mode. * v4rcp.M: new file, documents v4rcp support. Sat Nov 9 10:49:36 1996 Sam Hartman <hartmans@mit.edu> * login.c: Re-arrange to deal with compiling without krb4 support. [148] Fri Nov 8 20:59:27 1996 Tom Yu <tlyu@mit.edu> * login.c (k_init): Set up KRBTKFILE if converting krb5 tickets to krb4 but not getting them via password. Wed Nov 6 11:32:36 1996 Theodore Ts'o <tytso@rsts-11.mit.edu> * login.c (destroy_tickets): Just use global kcontext instead of creating a new krb5 context for no good reason. * krshd.c (main): * krsh.c (main): * krlogind.c (main): * krlogin.c (main): * krcp.c(main): Check the error return from krb5_init_context(), and print an error message if necessary. Fri Nov 1 23:11:21 1996 Sam Hartman <hartmans@planet-zorp.MIT.EDU> * login.c: print out system error if -1 returns. (destroy_tickets): Destroy krb4 tickets if we are converting as well as just for initial tickets. Fri Nov 1 21:00:01 1996 Sam Hartman <hartmans@mit.edu> * login.c: Have the this call must succeed comment before setuid, not the AIX login uid setting. Thu Oct 31 22:14:00 1996 Sam Hartman <hartmans@planet-zorp.MIT.EDU> * krlogind.c (doit): Remove tab3 because it isn't very useful and isn't always present. Thu Oct 31 19:19:54 1996 Sam Hartman <hartmans@mit.edu> * klogind.M kshd.M: document -r goes away [138] * krshd.c (doit): Do not support rhosts authentication. This was never used by any clients and the cruft in kcmd.c was creating problems. [138] * krlogind.c (do_krb_login): Remove broken rhosts support. [138] * kcmd.c: Remove ruserok and associated cruft along with killpg. [138] Tue Oct 29 10:09:39 1996 Theodore Y. Ts'o <tytso@mit.edu> * login.c: Make the defaults be to *not* to get Kerberos V4 tickets. There are currently bad interactions between defaulting and the default Kerberos V4 realm (which is still hard-coded to be ATHENA.MIT.EDU). Also added some miscellaneous code cleanups. Mon Oct 21 13:44:53 1996 Barry Jaspan <bjaspan@mit.edu> * kcmd.c: don't retry (and waste 7 seconds) on ECONNREFUSED, just fail immediately [krb5-appl/120] Fri Oct 18 17:26:51 1996 Barry Jaspan <bjaspan@mit.edu> * krsh.c, krlogin.c: don't print our own error message if kcmd returns -1 (it always printed something in that case, and error_message(-1) prints a mess [krb5-appl/70] Mon Sep 30 17:15:14 1996 Sam Hartman <hartmans@mit.edu> * login.c: Allow login -f to let you log in as root. Mon Sep 30 16:22:48 1996 Sam Hartman <hartmans@tertius.mit.edu> * login.c (stypeof): If TERM environment variable set, use it. * krlogind.c (doit): Do not use login -E; no one supports it besides login.krb5which also supports -f. Sun Sep 29 20:49:47 1996 Sam Hartman <hartmans@mit.edu> * login.c: Fix so it works with --without-krb4 option Fri Sep 20 18:23:53 1996 Sam Hartman <hartmans@planet-zorp.MIT.EDU> * login.c: Update so that we try to convert krb524 tickets after we setuid(), and so that we don't hard fail if cache writeout fail. Fri Sep 20 17:35:22 1996 Sam Hartman <hartmans@mit.edu> * login.c: Check to see if we got krb5 tickets at all times, regardless of wether we are converting to krb4. This helps us know when to kdestroy. Wed Sep 11 17:27:02 1996 Barry Jaspan <bjaspan@mit.edu> * login.c: fix a security-threating race condition: chown'ing the ccache to the user can be bad if the user can delete the file first and make it a symlink to something else. The solution is to re-create the ccache after login as setuid() to the user. Tue Sep 10 14:03:53 1996 Tom Yu <tlyu@mit.edu> * klogind.M, kshd.M, login.M, rcp.M, rlogin.M, rsh.M: remove ".so man1/header.doc" Fri Sep 6 13:22:46 1996 Theodore Y. Ts'o <tytso@mit.edu> * login.M: Document that login_krb4_convert is off by default. * login.c: Turn login_krb4_convert off by default, since it causes problems if you don't have krb524d running on the KDC. This is necessary because a Solaris socket bug causes login to hang for 45 seconds if krb524d isn't present on the KDC. Mon Sep 2 12:03:53 1996 Sam Hartman <hartmans@mit.edu> * krlogind.c rlogin.c (v5_des_write): Write out length plus encrypted data as one packet; this reduces latency by one RTT for interactive traffic with kernels that support schemes similar to RFC896, and reduces the number of packets with most other TCP stacks. Sat Aug 10 16:22:34 1996 Sam Hartman <hartmans@mit.edu> * krcp.c (source): Cast stb.st_size to a long before printing it. On NetBSD, it's a quad, so the following pointer is ignored and all files look null. We could special case NetBSD, but casting is somewhat cleaner if we aren't dealing with 2g+ files. e Mon Jun 24 09:48:11 1996 Theodore Ts'o <tytso@rsts-11.mit.edu> * krsh.c (main): Fix typo so that krsh doesn't exit when using the default port. Fri Jun 21 21:12:52 1996 Sam Hartman <hartmans@mit.edu> * configure.in : Make sure it works with the built-in libkrb4.a again. Fri Jun 14 13:19:30 1996 Sam Hartman <hartmans@mit.edu> * login.c: Add define to deal with krb_save_credentials possibly being called save_credentials, and to define krb_get_err_text if it is not defined by the krb4 library. * configure.in : check for krb_save_credentials and krb_get_err_text Thu Jun 13 14:24:50 1996 Sam Hartman <hartmans@mit.edu> * krlogind.c (doit): If using vendor login, make sure output flags are reasonable. Sat Jun 15 04:03:32 1996 Ezra Peisach <epeisach@kangaroo.mit.edu> * configure.in: Cleanup of tests whose results are not longer used with the pty library in place. Mon Jun 3 21:26:34 1996 Tom Yu <tlyu@mit.edu> * login.c: Ezra's patches to trim unsed arg from verify_krb_v5_tgt, etc. * Makefile.in,configure.in: allow compilation w/o krb4 (Ezra's patches) Sun May 19 15:22:06 1996 Sam Hartman <hartmans@mit.edu> * login.c (destroy_tickets main): Use a secure context Wed May 22 22:46:40 1996 Richard Basch <basch@lehman.com> * login.c (k_init): Set the default KRB5CCNAME environment variable consistently with other applications - FILE:/tmp/krb5cc_p<pid> Thu May 9 00:09:14 1996 Richard Basch <basch@lehman.com> * krlogind.c krshd.c: Use the replay cache associated with the default server name (rc_host*), like telnetd does. Mon May 6 14:06:21 1996 Richard Basch <basch@lehman.com> * login.c: SVR4 logins do not do motd or mailcheck normally; that is a function of /etc/profile. login.krb should act the same... Mon Apr 29 17:02:44 1996 Ken Raeburn <raeburn@cygnus.com> Merge with Cygnus sources, changes from Mark Eichin, Marc Horowitz, Chris Provenzano and me: * Makefile.in (install): Install correct set of man pages, and check for failures. * kshd.M, klogind.M: Renamed from kr*.M versions. * login.M: New file. Man page for login with some description of new features. * rlogin.M: Remove references to using program with target hostname as argv[0]. * rsh.M: Ditto. Also document -f, -F, -x options. * login.c: Massive changes. Split much functionality out of main and into separate file sections: terminal flag settings, Kerberos 4 and 5 support, UNIX password support, mail check, signal handler handling, some other support routines. Revamp controlling tty and process group handling. For AFS configuration, use setpag and run aklog. Try validating password using krb5. Always set tty flags, not just for rlogin session. When validating tickets, treat an existing key file that doesn't contain the key we think we want (possibly because DNS was spoofed) as an error condition. * Makefile.in (LOGINLIBS): List libkrb524.a here. (LIBOBJS): Not here. (login.krb5): Reverse the order of LIBOBJS and LOGINLIBS. * configure.in: Check for --with-afs. Add AFS libs and define SETPAG if supplied. * login.c (KRB5_GET_TICKETS, KRB4_GET_TICKETS, KRB_RUN_AKLOG): new macros selecting single signon options. krb5.conf profile support for control over authentication options, above the compile time selection. (conf_affirmative): new function, recognize yes/no in profile value. (login_get_kconf): new function, look for all [login] flags and set them in appropriate globals (via login_conf_set array.) (main, sleepexit, destroy_tickets): Check the new login_* flags. (main): rename KRB4_USE_524 to KRB4_CONVERT. * configure.in: Added checks for tcsetpgrp, tcgetpgrp, setpgid. * krlogind.c (control): Use tcgetpgrp if it's available. * loginpaths.h (RPATH, LPATH, LPATH_root): Define HP/UX 9.04 versions, conditionalized on __hpux and !hpux. * login.c and configure.in: instead of checking _IBMR2 and __sgi__, write configure tests to check for the existence of /etc/environment and /etc/TIMEZONE files, respectively. * forward.c (rd_and_store_for_creds) : If chown fails then only pass failure back if owner is different than intended owner. This is to make rsh.exp test work without requiring root privlidges. * login.c (main): Don't set TERM to an empty value. (stypeof) [__hpux]: Return null if unknown. * krlogin.c (catchild): remove hp/ux kludge because of aclocal.m4 fix. (speeds): test __hpux for hpux speed list. (main): test __hpux for use of FIOSSAIOSTAT and FIOSSAIOOWN (USE_TERMIO): test __hpux for bsdtty/ptyio headers. * krlogind.c: test __hpux for bsdtty/ptyio headers. (doit): test __hpux for use of setpgrp2. * krcp.c (main): test __hpux as well for remsh vs. rsh. * krcp.c (des_write): Make sure the buffer for the encrypted data is large enough. Only return an error in malloc fails. * krsh.c (main): Always turn on anyport -A option. * krlogind.c (ptsname): Declare if it's going to be used. * krshd.c (main): Use basename of argv[0] for progname. * login.c (dofork): On linux, TIOCNOTTY causes us to die on a SIGHUP, so don't even try it. Sun Apr 21 12:52:35 1996 Richard Basch <basch@lehman.com> * krshd.c: If checksumming is required & ALWAYS_V5_KUSEROK is defined, incorrect messages were being displayed for V4 clients. Additionally, various errors were not being displayed with the trailing newline. Also, one could not specify -c in inetd.conf, because of the variable initialization; initialization has been corrected to allow either checksumming or ignoring the checksum. Sun Apr 21 00:30:28 1996 Sam Hartman <hartmans@mit.edu> * krshd.c krlogind.c: Implement -i. Rewrite error message having to do with checksums. * krshd.Mkrlogind.M : Document -i, remove documentation about taking options from name of daemon. Clean up checksum documentation. * krlogind.c (do_krb_login): Fix up error messages for checksums. Configuration errors are presented for situations where -c and -i are used together, or where -4 and -c are used together. Thu Apr 18 19:48:47 1996 Sam Hartman <hartmans@mit.edu> * Makefile.in: Fix spaces by converting to tabs. * krlogind.c: Take patches from Doug Engert <deengert@anl.gov> to allow login to work with vendor logins. Also, fix packet-mode bug; we have some hope of working on non-Solaris streams pty code. Wed Apr 17 13:46:57 1996 Theodore Y. Ts'o <tytso@mit.edu> * configure.in (LOGINLIBS): Remove DECLARE_SYS_ERRLIST since it's no longer necessary. * krcp.c (verifydir, allocbuf, rsource, source, sink): Don't use sys_errlist[]; just call error_message() instead, since we depend on com_err anyway. * krshd.c (recvauth): * krlogind.c (recvauth): Don't actually check the checksum unless it is required. Old (pre-beta 5) clients sent a checksum of random garbage (such as their pid) which is impossible to actually check on the server side. (Grad student stupidity strikes again.) (fatalperror): Don't use sys_errlist[] to get the right error message; just depend on com_err instead, since we're using it anyway. * krshd.c (doit): * krlogind.c (do_krb_login): Fix logic so that if checksums are required, and the checksum is valid, don't syslog the stupid warning message about "Checksums are only required for v5 clients...." * krcp.c, krshd.c, krlogind.c: Miscellaneous -Wall cleanups * krlogind.c (getpty): Removed dead code. Tue Apr 16 11:33:33 1996 Sam Hartman <hartmans@mit.edu> * krlogind.c kshd.c (main): Drop support for handling options in rlogind's name. Sun Apr 14 03:41:49 1996 Sam Hartman <hartmans@zygorthian-space-raiders.MIT.EDU> * krlogind.c (fatalperror): Only declar sys_errlist if needed. Sat Apr 13 17:47:36 1996 Sam Hartman <hartmans@mit.edu> * krshd.c (doit): Use setsid instead of setpgrp if you have it. Note this doesn't work for Ultrix. * krlogind.c (doit): Don't call setpgrp or setsid; let pty library do that for us. Fri Apr 12 23:38:25 1996 Richard Basch <basch@lehman.com> * krlogind.c (cleanup): Destroy any forwarded credentials at the end of the login session (they were placed in an unusual location anyway, so the chance that someone will be trying to reuse those credentials is minimal) Thu Apr 11 00:22:51 1996 Richard Basch <basch@lehman.com> * kcmd.c: Cleaned up whitespace and removed commented & unused cruft * krlogind.c, krshd.c: Allow the recvauth routine to find any key in the keytab for which the user is trying to login. The host may be known as many names. Additionally, for krlogind, clean up the error handling for bad authentication (potential null dereference and a misleading message because of the wrong authentication system being used) Sun Apr 7 22:46:07 1996 Ezra Peisach <epeisach@kangaroo.mit.edu> * krshd.c: Add an option -L to pass certain environment variables to the client. Wed Apr 3 17:09:19 1996 Richard Basch <basch@lehman.com> * krlogind.c: Under Solaris, when the connection pipe goes away, zero bytes are returned. Since we are using blocking read calls, and the net_read function deals with interrupted/resumed reads, consider zero bytes to be be a terminated connection, so as not to spin. Mon Apr 1 10:12:44 1996 Richard Basch <basch@lehman.com> * loginpaths.h: Leading/trailing colons should not be there based on the variable usage in the code. Also, the tests for Solaris were incorrect. Fri Mar 29 16:22:18 1996 Richard Basch <basch@lehman.com> * kcmd.c, krlogin.c, krsh.c, krcp.c: Allow for a proxy forwarder to be specified Sat Mar 23 17:20:00 1996 Sam Hartman <hartmans@tertius.mit.edu> * krcp.c (des_write): Use krb5_net_write instead of write, because most parts of rcp that call this code ignore the return value and we want to reblock properly. * krshd.c (doit): Don't use non-blocking IO; it is unnecessary and may cause problems. Fri Mar 22 13:27:40 1996 Richard Basch <basch@lehman.com> * krshd.c: use the library routines to do v4 to v5 principal translation, for a more accurate representation. Wed Mar 20 19:36:21 1996 Richard Basch <basch@lehman.com> * krlogind.c: use the library routines to do v4 to v5 principal translation, for a more accurate representation. Tue Mar 19 20:11:28 1996 Richard Basch <basch@lehman.com> * kcmd.c (ruserok): declare the function as taking const char * instead of char * (Solaris 2.5 refuses to compile it, otherwise). Tue Mar 12 23:42:50 1996 Ken Raeburn <raeburn@cygnus.com> * configure.in: Use AC_HEADER_STDARG. Tue Mar 12 17:52:08 1996 Ezra Peisach <epeisach@kangaroo.mit.edu> * krshd.c (doit): For encrypted rcp, fix logic in determining executable to run. Mon Feb 26 03:28:44 1996 Sam Hartman <hartmans@tertius.mit.edu> * configure.in: call USE_ANAME. Sun Feb 25 18:50:45 1996 Sam Hartman <hartmans@tertius.mit.edu> * krlogind.c (v5_des_read): Fix server side of bug in detecing eof on the network connection. Same as client change: v5_des_read needs to return 0 if read returns <= 0, notjust a strict inequality. Mon Feb 12 22:41:06 1996 Theodore Y. Ts'o <tytso@dcl> * kcmd.c (kcmd): Fix lint flame (added missing cast). Fri Feb 9 21:43:50 1996 Sam Hartman <hartmans@hartman.mit.edu> * krsh.c (main): Only print secure_message if encrypt_flag set. Fri Feb 9 20:18:48 1996 <hartmans@mit.edu> * krlogind.c (recvauth): Fix v4 incompatability created by checksum code; if using v4, don't try to verify a v5 checksum. Fri Feb 2 16:10:56 1996 Sam Hartman <hartmans@tertius.mit.edu> * configure.in (save_path): Look for "ucb" varients in /usr/athena/bin if --enable-athena specified. * krsh.c krlogin.c krcp.c (try_normal): If --enable-athena, don't quit just because we are encrypted. Thu Feb 1 00:09:13 1996 Sam Hartman <hartmans@tertius.mit.edu> * rcp.M: Fix typo. * krcp.c (des_write): If rcp tries to write to stdin, redirect it to stdout. That way it works with pipes; the right thing is for rcp to not try and do this, but introducing remread and remwrite as variables is significantly more work for only slightly better code. (main): Use rsh encryption; not user-to-user. Note that we still support the answer_auth mechanism for incoming connections so older clients work, but this is depricated. (send_auth): expunged with pleasure; answer_auth should go in a a version or two. Wed Jan 31 16:24:50 1996 Sam Hartman <hartmans@tertius.mit.edu> * krsh.c (main): Print SECURE_MESSAGE when appropriate. * krshd.c (doit): Fork and handle pipes either if stderr signal processing is enabled *or* encryption is enabled. Rsh always enables stderr, but rcp won't. (SECURE_MESSAGE): Moving to client where it belongs, so the stderr channel doesn't get corrupted for rcp. Besides, the client can determine if it is talking to a tty and only print this message to a tty. * krlogind.c (recvauth): Pas ccache to rd_and_store_for_creds * krshd.c (recvauth): Pass address of ccache to rd_and_store_for_creds (ccache): new global variable. (cleanup): Destroy ccache if we have one. (doit): Destroy cache on normal terination. * forward.c (rd_and_store_for_creds): Take a pointer to a ccache; we should provide the caller with a way of destroying forwarded credentials. Tue Jan 30 17:56:49 1996 Sam Hartman <hartmans@tertius.mit.edu> * krshd.c (envinit): Expand to have space KRB5_CCNAME (doit): Put krb5_ccname at the end of envinit; this is handled differently that other variables, because TZ may or may not beset, so our position cannot be fixed. Sat Jan 27 18:40:31 1996 Sam Hartman <hartmans@tertius.mit.edu> * kcmd.c (kcmd): We no longer need F_SETOWN as nothing in appl/bsd handles oob data with signals any more. Fri Jan 26 00:37:23 1996 Sam Hartman <hartmans@tertius.mit.edu> * krlogin.c (reader): Deal with exceptions even while writing. (reader): Fix bogus select bug; actually select on writing Wed Jan 24 00:34:42 1996 Sam Hartman <hartmans@tertius.mit.edu> * krlogind.M krshd.M: Update to document new options. * Makefile.in (install): Install as kshd and klogind not krshd and krlogind. * krshd.c (main): Use krlogind-style options (-54kce) * krlogind.c (main): Change option parsing to support new format. (do_krb_login): Use auth_ok and auth_sent masks instead of passed_* Tue Jan 23 18:10:55 1996 Sam Hartman <hartmans@tertius.mit.edu> * krshd.c (recvauth): Use the correct username in strlen call for allocating chksumbuf. * krlogind.c (recvauth): Code to copy checksum verification code. Mon Jan 22 15:14:11 1996 Sam Hartman <hartmans@tertius.mit.edu> * krshd.c (recvauth): Update to expect port in checksum. * kcmd.c (kcmd): Include port in string of checksumed data to distinguish between encrypted and unencrypted rlogin. Mon Jan 22 18:14:05 1996 Ezra Peisach <epeisach@kangaroo.mit.edu> * krcp.c: Use KRB5_STDARG_P. * configure.in: Add KRB5_CHECK_PROTOS for prototyps definitions. Fri Jan 19 10:45:29 1996 Sam Hartman <hartmans@tertius.mit.edu> * krshd.c (recvauth): Verify checksum against command line and remote user. (recvauth): Fix accidental memory leak with authenticator and fix include correct username in checksum * kcmd.c: Send authenticator with checksum of command line and remote user. * krlogin.c (des_read): Return 0 or -1 on close/error respectively. Wed Jan 17 15:14:33 1996 Sam Hartman <hartmans@tertius.mit.edu> * krlogin.c (reader): Use select to find out-of-band data, not signals. (oob): No longer a signal handler; just a function. (writer): get rid of copytochild setup as sigurg no longer needed (main): Don't block SIGURG * configure.in : Include sys/time.h check Mon Jan 15 16:16:07 1996 Sam Hartman <hartmans@tertius.mit.edu> * login.c (main): ttyslot usable here as well * krlogind.c (doit): update_utmp can use ttyslot. Thu Jan 11 12:40:08 1996 Ezra Peisach (epeisach@paris) * krsh.c, krlogin.c: (main): Ultrix cc does not support automatic aggregate initiailzation of structures. Thu Jan 11 11:27:04 1996 Ezra Peisach <epeisach@kangaroo.mit.edu> * krcp.c (error): Convert to use varargs. * configure.in: Check for stdarg.h Wed Jan 10 21:26:20 1996 Theodore Y. Ts'o <tytso@dcl> * kcmd.c (getport): Clear the sin structure to be zero. (From Doug Engert.) * krsh.c (main): Added code to default port to 544 if service not found. (From Doug Engert.) * krlogin.c (main): Added code to default port to 543 or 2105 if service not found. (From Doug Engert.) * login.c (main): Save KRB5CCNAME environment variable, which may have been set by forward.c. Add code for SGI to set environment for its /etc/TIMEZONE (untested). Don't print MOTD twice on Suns, added #ifdef NO_MOTD. (Patches from Doug Engert). * kcmd.c: Removed extern global of krb5_kdc_req_sumtype, which wasn't being used anyway. Tue Jan 9 22:51:16 1996 Theodore Y. Ts'o <tytso@dcl> * forward.c (get_for_creds): Removed no longer used function. * kcmd.c (kcmd): Convert from using get_for_creds() from forward.c to using the official library routine, krb5_fwd_tgt_creds(). Fri Dec 22 17:42:11 1995 Theodore Y. Ts'o <tytso@dcl> * login.c (main): If HAVE_SHADOW is defined, and no shadow password entry is availble, try using the password entry in the password file. Tue Dec 19 17:11:37 1995 Theodore Y. Ts'o <tytso@dcl> * kcmd.c: Also include unistd.h, if it's available. Tue Dec 5 20:44:39 1995 Ezra Peisach <epeisach@kangaroo.mit.edu> * configure.in: Use krb5util library. * login.c (main): Change two-argument call to syslog to three arguments to handle screw cases in hostnames. Fri Dec 1 17:25:02 1995 Theodore Y. Ts'o <tytso@dcl> * login.c (main, dofork): Applied patch from Scott Schwartz <schwartz@galapagos.cse.psu.edu> Under SunOS, and maybe other systems, there is a a problem with krlogind.c and a similar problem with login.c as distributed with K5.5. The bug is that rlogind forks a child but retains a controlling tty. If the child is in the same process group as the parent, which is will if you don't use a job control shell (chsh /bin/rc), keyboard signals will kill the daemon. telnetd dissociates itself properly, but then login.krb5 waits for the shell to finish, but login.krb5 has the same ctty as the shell and is in the same process group, so it has the same problem. In BSD you used to be able to give up your ctty at will, but SunOS seems to have setsid as the only mechanism to perform that action, and setsid can only succeed in limited circumstances. Rlogind ought to be fixed to behave more like telnetd, but independent of that, login.krb5 needs to be patched if kerberos is to work properly under SunOS. Sun Nov 12 12:39:23 1995 Sam Hartman <hartmans@tertius.mit.edu> * krlogind.c (doit): Clear iextn for NetBSD and other 4.4-based systems so that ctrl-o isn't special. Sat Oct 21 17:33:37 1995 Sam Hartman <hartmans@tertius.mit.edu> * login.c (main): Don't set LOGNAME twice. Sun Nov 12 04:44:50 1995 Mark W. Eichin <eichin@cygnus.com> * krshd.c (doit): drag TZ= from parent environment into envinit to pass to child. (envinit, TZENV): add one more slot for optional TZ, and mark it. Thu Nov 2 16:16:47 1995 Ezra Peisach <epeisach@kangaroo.mit.edu> * krlogin.c, krcp.c, krsh.c (main): If invoked with -D port, do not die if entry is missing from /etc/services. Mon Oct 16 17:27:43 1995 Sam Hartman <hartmans@tertius.mit.edu> * login.c (main): Don't print warning about no tickets obtained if we didn't ask for a password. Also, define LOGNAME for so sysvish systems are happy. Patch from ramus@nersc.gov. Wed Sep 06 14:20:57 1995 Chris Provenzano (proven@mit.edu) * krcp.c, krlogin.c, krlogind.c, krsh.c, krshd.c : s/keytype/enctype/g, s/KEYTYPE/ENCTYPE/g Sun Aug 27 15:35:04 1995 Ezra Peisach <epeisach@kangaroo.mit.edu> * rlogin.M: Document -f and -F options. Mon Aug 7 17:32:29 1995 Sam Hartman <hartmans@tertius.mit.edu> * krlogind.c: Close the write side of the syncpipe in the parent so we get SIGPIPE if child dies. * login.c (main): Use new interface to pty_update_utmp * configure.in (LOGINLIBS): Check for utmp.h and utmpx.h. * krlogind.c (doit): Use new format for pty_update_utmp * Include utmp.h because libpty.h no longer does. Fri Aug 4 00:50:41 1995 Tom Yu <tlyu@dragons-lair.MIT.EDU> * krlogind.c: don't include utmp.h, since libty.h grabs it. Wed Aug 2 13:06:02 1995 Sam Hartman <hartmans@tertius.mit.edu> * krlogind.c (main): call pty_init()call pty_init() Tue Aug 1 08:43:22 1995 Sam Hartman <hartmans@tertius.mit.edu> * Makefile.in : Remove references to logutil.c and logutil.o * krshd.c (doit): Replace logwtmp with pty_logwtmp * login.c (main): use pty_update_utmp not update_utmp * logutil.c: Removed because all its functionality is incorperated into libpty. * krlogind.c (doit): Pass length of line to pty_getpty Mon Jul 31 17:07:59 1995 Sam Hartman <hartmans@tertius.mit.edu> * login.c (main): Don't call TIOCSETD under Posix. * Include iexten in terminal flags. * krlogin.c: Don't include termio.h here either. * login.c: Remove special casing of AIX to include termio.h; it breaks almost all terminal handling, because it's the compatibility file for applications written for the RT. Instead, just define CNUL if not already defined by ttychars.h Sat Jul 29 04:37:33 1995 Tom Yu <tlyu@dragons-lair.MIT.EDU> * configure.in: Don't link with -lkadm Fri Jul 28 16:49:02 1995 Sam Hartman <hartmans@tertius.mit.edu> * Makefile.in (LOCAL_LIBRARIES): include -lpty; also included in DEPLOCAL_LIBRARIES. * krlogind.c (doit): Use pipe for synchronization so pty can be opened in slave. Use libpty for pty handling. (cleanup): Use pty_cleanup to do most work. Thu Jul 27 15:02:03 EDT 1995 Paul Park (pjpark@mit.edu) * krshd.c - Check for interrupted select. Should fix bug #1555. Thu Jul 13 17:49:54 1995 Sam Hartman <hartmans@tertius.mit.edu> * configure.in : Short circuit the streams test for AIX to false because AIX strops.h trashes definition of _IO from sys/ioctl.h. I think this is fixed in AIX4, so the test is only bypassed for AIX3. Tue Jul 11 12:50:16 1995 Sam Hartman <hartmans@tertius.mit.edu> * krlogind.c (getpty): Use ptsname before ttyname; it has a higher chance of doing what we want. Fri Jul 7 15:40:42 EDT 1995 Paul Park (pjpark@mit.edu) * Makefile.in - Remove all explcitit library handling. * configure.in - Add USE_<mumble> and KRB5_LIBRARIES. Wed Jul 5 20:03:37 1995 Theodore Y. Ts'o (tytso@dcl) * krcp.c, krlogin.c, krlogind.c, krshd.c, login.c: Remove declaration of errno altoghether. "extern int errno;" is always wrong. * login.c (main): Don't use the TIOCLSET ioctl unless we're not using POSIX_TERMIOS. Don't just blindly set the file status flags to 0. Instead, do a fcntl(0, F_GETFL), and then reset the nonblocking flags. Sun Jul 2 19:48:27 1995 Sam Hartman <hartmans@tertius.mit.edu> * krcp.c: make errno extern * krshd.c: errno should be extern so it doesn't mask the libc definition in AIX. Tue Jun 27 23:50:56 1995 Tom Yu (tlyu@dragons-lair) * krlogin.c: don't redeclare noltc, defltc if we happen to have TIOCGLTC in addition to POSIX_TERMIOS Tue Jun 27 16:18:49 EDT 1995 Paul Park (pjpark@mit.edu) * configure.in - When checking number/type of arguments to {get,set}pgrp attempt to set __STDC__ in a vain attempt to ensure that we get function prototype checking turned on. OSF/1's native compiler didn't really care what's passed as arguments unless __STDC__'s set. * krcp.c - Change usage of BUFSIZ to RCP_BUFSIZ. Remove & from in front of array. It's redundant. * krlogin.c - Change usage of BUFSIZ to RLOGIN_BUFSIZ. Add signal name parameter to signal handlers to conform to prototype. * krlogind.c - Change usage of BUFSIZ to RLOGIND_BUFSIZ. Cast 4th argument to setsockopt(2) to be const char *. * krsh.c - Change usage of BUFSIZ to RSH_BUFSIZ. Cast 4th argument to setsockopt(2) to be const char *. * krshd.c - Change usage of BUFSIZ to RSHD_BUFSIZ. Thu Jun 22 14:36:46 1995 Theodore Y. Ts'o <tytso@dcl> * configure.in: Change AC_HAVE_HEADERS with AC_CHECK_HEADERS, and check for string.h as well. * krsh.c: Don't include ext-proto.h; move the #include of the header files which we actually needed into krsh.c, using the autoconf standard define's. Wed Jun 21 17:29:27 1995 Ezra Peisach <epeisach@kangaroo.mit.edu> * login.c: Change RETSIGTYPE to krb5_sigtype to be consistant. * configure.in (LOGINLIBS): Add KRB5_SIGTYPE to declare krb5_sigtype. Tue Jun 20 13:00:25 1995 Tom Yu (tlyu@dragons-lair) * krlogin.c: HAS_STDLIB_H -> HAVE_STDLIB_H Mon Jun 19 13:34:23 EDT 1995 Paul Park (pjpark@mit.edu) * login.c - Change setluid call to check for luid and then set it if it fails, also make this logic conditional under HAVE_SETLUID. * configure.in - For OSF/1 systems where libsecurity is present, set HAVE_SETLUID. We'll need to determine similar tests for other extended security systems that we are to support in the future. Thu Jun 15 17:32:20 EDT 1995 Paul Park (pjpark@mit.edu) * Makefile.in - Change explicit library names to -l<lib> form, and change target link line to use $(LD) and associated flags. Also, remove DBMLIB, it was not used. Also, for K4, use KRB4_LIB and KRB4_CRYPTO_LIB, these were split out. * configure.in - Remove dbm library checks, these are no longer needed with the Berkeley database code. Also, add shared library usage check. Sat Jun 10 22:56:10 1995 Tom Yu (tlyu@dragons-lair) * forward.c, kcmd.c, krcp.c, krlogind.c, krshd.c: krb5_auth_context redefinitions Fri Jun 9 18:26:30 1995 <tytso@rsx-11.mit.edu> * configure.in: Remove standardized set of autoconf macros, which are now handled by CONFIG_RULES. Wed May 31 17:16:44 1995 Tom Yu (tlyu@dragons-lair) * loginpaths.h: #ifdef ultrix => #ifdef __ultrix Sun May 21 16:36:39 1995 Ezra Peisach <epeisach@kangaroo.mit.edu> * loginpaths.h: Add NetBSD paths. * login.c: Define TAB3 to 0 if non existant * krlogin.c (mode): ifdef code based on TABDLY existing on machine. (netbsd lacks this). * krcp.c: Declare sys_errlist only if needed by the OS. * configure.in: Add DECLARE_SYS_ERRLIST Check for libcrypt defining the function crypt Mon May 15 10:43:30 1995 <tytso@rsx-11.mit.edu> * login.c (main): Only try to use TIOCSETD if it is defined (instead of relying on _IBMR2 *not* being defined). Only try to use TIOCNXCL if it is defined. * krcp.c: If setreuid() is emulated using setresuid(), #define HAVE_SETREUID so it gets used. Sat May 13 08:59:38 1995 Ezra Peisach <epeisach@kangaroo.mit.edu> * krshd.c (recvauth): Use krb5_auth_con_genaddrs to set the port on the connection so that credential forwarding works. Tue May 9 08:17:18 1995 Ezra Peisach (epeisach@kangaroo.mit.edu) * krshd.c (main): Cast a sockaddr_in * to sockaddr * in call to accept. * kcmd.c: Add <stdlib.h> * krcp.c: Add <stdlib.h>. Sat May 6 18:12:37 1995 Ezra Peisach <epeisach@kangaroo.mit.edu> * krcp.c (answer_auth): Added const declaration to filenames. Fri May 05 09:16:16 1995 Chris Provenzano (proven@mit.edu) * krcp.c (answer_auth()): Requires two new args that are passed from the command line. The first -c is to pass the filename of the remote credential cache. The second -C is to pass the filename of the remote krb5.conf file. Thu May 04 23:53:23 1995 Chris Provenzano (proven@mit.edu) * krcp.c (answer_auth()): Don't destroy the credential cache. Wed May 03 20:10:39 1995 Chris Provenzano (proven@mit.edu) * krcp.c (answer_auth()): Set auth_context = NULL before using it. Wed May 03 03:30:51 1995 Chris Provenzano (proven@mit.edu) * krlogind.c, krshd.c: (krb5_compat_recvauth()): No longer needs the rc_type arg. Tue May 2 22:12:39 1995 Theodore Y. Ts'o (tytso@dcl) * krcp.c (main): Don't try to play uid swapping games if the effective uid is not zero. * kcmd.c (kcmd): Bug fix to jik's bug fix. (Caused by our code drift since jik's changes went in, and not sufficiently careful checking of jik's patches before applying it.) Mon May 01 15:56:32 1995 Chris Provenzano * kcmd.c (kcmd()): Bug fixes from jik. * krlogind.c (recvauth()): Changes to auth_context to better support full addresses, for rd_cred() and friends. Sat Apr 29 01:26:06 1995 Theodore Y. Ts'o <tytso@dcl> * Makefile.in (login.krb5): Link the libraries twice due to circular dependency in the libraries. (read_password in libdes425.a depends on krb5_read_password in libkrb5.a) Fri Apr 28 20:33:06 1995 Theodore Y. Ts'o <tytso@dcl> * login.c (main): Don't use setreuid() to play games with the real uid, since not all systems have setreuid(). This method of communicating to in_tkt what the correct owner of the ticket file is completely broken, anyway. We skip the setreuid() entirely, and then chown the ticket file to the correct owner and group afterwards. Fri Apr 28 17:59:19 1995 Mark Eichin <eichin@cygnus.com> * Makefile.in (KLIB): include KRB4_LIB directly, to satisfy both versions of the dependencies. Fri Apr 28 16:55:14 EDT 1995 Paul Park (pjpark@mit.edu) * Makefile.in - change position of KRB4_LIB for krshd and krlogind so that it links correctly for both --with-krb4 and --with-krb4=/usr/athena. Fri Apr 28 16:12:57 1995 Mark Eichin <eichin@cygnus.com> * configure.in (PATH): use internal AC_PROG_ECHO_N because change in path might change behavior of echo (example: solaris, native shell, with GNU echo (-n) in user path, but only Solaris echo (\c) in path here.) Fri Apr 28 07:52:45 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu> * login.c: Lots of lint cleanup; declare functions before they are used, add appropriate return types (int or void) to functions as necessary, etc. Thu Apr 27 21:44:17 1995 Ezra Peisach (epeisach@kangaroo.mit.edu) * login.c: Remove definition of krb_err_txt. krb.h defines it. Thu Apr 27 17:41:06 1995 Mark Eichin <eichin@cygnus.com> * Makefile.in (krshd, login.krb5, krlogind): KRB4_LIB needs to appear before KLIB since it uses des425. Thu Apr 27 14:36:54 1995 Mark Eichin <eichin@cygnus.com> * Makefile.in (LOCALINCLUDE): get kerberosIV headers for login.c (login.krb): link against krb4 libs. * configure.in: check AC_CONST so it works. Thu Apr 27 13:54:21 1995 Mark Eichin <eichin@cygnus.com> * configure.in: use WITH_KRB4 as-is. * Makefile.in (krshd, krlogind): use KRB4_LIB directly. Thu Apr 27 01:09:19 1995 Ezra Peisach <epeisach@kangaroo.mit.edu> * krcp.c (answer_auth): Should not call krb5_cc_close after krb5_cc_destroy. (encrypted rcp failed). * krlogind.c (main): -S option was not getting a keytab. (passing a char * to krb5_compat_recvauth). * krshd.c (recvauth): extract the client principal from ticket before calling krb5_kuserok on a NULL principal. (main): -S option was not getting a keytab (passing a char *). * krcp.c: (main): Missing htons on port number when specified on command line. Wed Apr 26 21:09:34 1995 Chris Provenzano (proven@mit.edu) * kcmd.c (kcmd()) : Don't use hp->h_name use host_save instead. Wed Apr 26 17:43:08 1995 Mark Eichin <eichin@cygnus.com> * logutil.c (EMPTY): linux has UT_UNKNOWN, not EMPTY. Wed Apr 26 09:41:35 1995 Ezra Peisach <epeisach@kangaroo.mit.edu> * krlogind.c (main): LOG_AUTH in openlog arguments in wrong place. (recvauth): Do not copy principal on a V4 request. The ticket portion is not set by krb5_compat_recvauth for these. * configure.in: Check for libutil. Under OSF/1, logwtmp is stored there. Wed Apr 26 07:19:18 1995 Chris Provenzano (proven@mit.edu) * krlogind.c (doit()) : If TIOCOTTY is defined unset the controlling tty before setting it to another tty. Tue Apr 25 21:23:28 1995 Chris Provenzano (proven@mit.edu) * forward.c (rd_and_store_for_creds()) : Rewritten to use auth_context and the new krb5_rd_creds(). * forward.c (get_for_creds()) : New function replacing krb5_get_for_creds() and uses auth_context and new krb5_mk_creds() routine. * kcmd.c (kcmd()): Use new get_for_creds() routine. * krlogind.c (recvauth()): Use new rd_and_store_for_creds() routine. Sat Apr 22 00:42:22 1995 Theodore Y. Ts'o (tytso@dcl) * rlogind (main, doit): The variable krb5_override_default_realm is obsolete. Use the krb5_set_default_realm function instead. * krshd.c (main, doit): The variable krb5_override_default_realm is obsolete. Use the krb5_set_default_realm function instead. Fri Apr 21 21:11:17 1995 Theodore Y. Ts'o (tytso@dcl) * krshd.c: Add #include for <sys/stat.h>, which is now needed. Fri Apr 21 17:18:57 1995 Mark Eichin <eichin@cygnus.com> rlogin testing changes from ian@cygnus.com. Fri Apr 21 17:13:48 1995 Mark Eichin <eichin@cygnus.com> More changes from ian@cygnus.com to support testing. Fri Apr 21 14:07:15 1995 Mark Eichin <eichin@cygnus.com> Added Ian's changes with minor tweaks. These are used by the testsuite. Fri Apr 07 15:46:54 1995 Chris Provenzano (proven@mit.edu) * configure.in, krlogind.c, krsh.c, krshd.c, login.c, logutil.c. A bunch of patches from Ezra to get BSD to work on The Alpha that looked reasonable. Mon Mar 27 07:56:26 1995 Chris Provenzano (proven@mit.edu) * krcp.c (send_auth()): Use new calling convention for krb5_rd_req(). * krshd.c (recvauth()): Use new calling convention for krb5_compat_recvauth(). * krlogind.c (recvauth()): Use new calling convention for krb5_compat_recvauth().

(recvauth): Pass srvtab to krb5_compat_recvauth. * krlogind.M: Document -S, -M, and -L. Fri Mar 24 15:04:25 1995 Ian Lance Taylor <ian@cygnus.com> * krcp.c (forcenet): New global vraiable. (main): Accept -D and -N arguments. Pass Kerberos realm to remote rcp execution. (hosteq): If -N specified, always return 0. * rcp.M: Document -D and -N. * krshd.c (ARGSTR): Add "P:" to KERBEROS version. (kprogdir): New global variable. (main): Handle -P. (path): Remove global variable. (path_rest): Remove explicit size. (envinit): Use 0 instead of path. (PATHENV): define. (doit): Use kprogdir variable instead of KPROGDIR macro when setting path. Build path in allocated memory rather than using a fixed size array. If the command starts with "rcp ", force use of kprogdir/rcp if it exists. * krshd.M: Document -P. Thu Mar 23 18:18:31 1995 Ian Lance Taylor <ian@cygnus.com> * krshd.c (ARGSTR): Add S:M:A to KERBEROS version. (srvtab): New global variable. (krb5_override_default_realm): Declare. (main): Handle -S, -M and -A arguments. Call SO_REUSEADDR on socket if debug_port set. (doit): If -A used, allocate a random port for the stderr stream, rather than allocating a reserved port. Don't call initgroups if not changing the uid. (recvauth): Pass srvtab to krb5_compat_recvauth. * krshd.M: Document -S, -M, and -A. * krsh.c (main): Accept -A, and pass it to kcmd. * rsh.M: Document -A. * kcmd.c (kcmd): Add new argument anyport. If it is set, permit any port for the stderr stream, rather than requiring a reserved port. Initialize ret_cred to NULL. * krcp.c (main): Pass 0 for anyport to kcmd. * krlogin.c (main): Pass 0 for anyport to kcmd. Thu Mar 23 23:23:25 1995 Theodore Y. Ts'o <tytso@dcl> * Makefile.in (krshd): Move $(K4LIB) after $(KLIB) so that if we're using des425, the V5 crypto library can be picked up. * configure.in: Use the correct path to find libdes425 Thu Mar 23 20:22:57 1995 Mark Eichin <eichin@cygnus.com> * logutil.c (update_wtmp): initialize ut from ent the way the V4 code did. Appears to handle SunOS case (when nearly all of the ifdef's are off) correctly now. Tue Mar 14 16:08:08 1995 <tytso@rsx-11.mit.edu> * Makefile.in, configure.in: Use the libdes425 library so that the DES code doesn't get dragged in twice. * krlogind.c: Include <sys/time.h> so that Linux can get the FD_SET macros. * kcmd.c (kcmd): Close the credentials cache when you're done with it. * krlogind.c (doit): Always initialize the Krb5 error table. * krlogind.c (main, doit): Minor type fixes to gethostbyname(), accept(). Tue Mar 14 12:30:23 1995 Chris Provenzano (proven@mit.edu) * kcmd.c (kcmd()): Don't pass any data to sendauth() to be checksummed. The remote side doesn't check it anyway. Fri Mar 10 18:32:22 1995 Theodore Y. Ts'o <tytso@dcl> * kcmd.c (kcmd): Initialize ret_cred to zero so that in case of an error, we don't try to free stack garbage. Fri Mar 10 11:09:34 1995 Chris Provenzano (proven@mit.edu) * kcmd.c (kcmd()) Use new calling convention for krb5_sendauth(). * krcp.c () Use new calling convention for krb5_mk_req_extended(). Thu Mar 2 12:26:29 1995 Theodore Y. Ts'o <tytso@dcl> * Makefile.in (ISODELIB): Remove reference to $(ISODELIB). Wed Mar 1 11:54:50 1995 Theodore Y. Ts'o <tytso@dcl> * configure.in: Remove ISODE_INCLUDE and ISODE_DEFS, replace check for -lsocket and -lnsl with WITH_NETLIB check. Tue Feb 28 01:41:04 1995 John Gilmore (gnu at toad.com) * forward.c, kcmd.c, krcp.c, krlogin.c, krlogind.c, krsh.c, krshd.c: Avoid <krb5/...> and <com_err.h> includes.

Wed Jan 18 01:07:56 1995 Mark Eichin <eichin@cygnus.com> * configure.in: undo streams test. It turns out that we want sunos to *fail* that test, since it doesn't have a streams PTEM module anyhow. * krlogind.c: don't include sys/tty.h and sys/ptyvar.h if we don't HAVE_STREAMS already. * krlogin.c: do the same thing. Fri Jan 13 15:23:47 1995 Chris Provenzano (proven@mit.edu) * Added krb5_context to all krb5_routines * krsh.c (main): Use htons(debug_port). Wed Jan 11 01:25:09 1995 Mark Eichin <eichin@cygnus.com> * logutil.c (update_wtmp): declare missing variables if HAVE_SETUTENT isn't set. (update_utmp): declare tty at top of function. Tue Jan 10 19:43:18 1995 Mark Eichin (eichin@cygnus.com) * krlogin.c (doit): use exit_handler for signal exits, don't use exit directly. (exit_handler): new function, avoids type collision from misusing exit directly as a signal handler. Tue Jan 10 15:23:31 1995 Richard Basch (probe@tardis) * configure.in: Streams test needs to include sys/types.h * krsh.c: Include sys/time.h (linux) Mon Jan 9 21:48:54 1995 Theodore Y. Ts'o (tytso@dcl) * kcmd.c, krlogin.c, krcp.c: Always include fcntl.h, and never sys/fcntl.h. * krshd.c: Always define the Kerberos V4 data structures.

Mon Jan 2 12:35:18 1995 Richard Basch (probe@tardis) * krsh.c * krshd.c Added encrypted rsh support. It still isn't entirely secure; as the command-line could be spoofed by an active attack, but the data sharing is... * krlogind.c Ultrix doesn't have a fully functional POSIX termios. * krshd.c Cleaned up some of the #ifdef's and code duplication. Fixed decl. of return variable for getopt() [int not char] Fri Dec 30 18:35:50 1994 Richard Basch (probe@tardis) * krlogin.c Don't need: #ifdef _AIX, #undef _BSD, #endif * Makefile.in Fixed man page installation when build tree != source tree * configure.in No need to do the fcntl check Changed GETPGRP_ONEARG detection (and assign it when it takes one argument, not void). * logutil.c * login.c Tidied up the code a bit. Do not rely on NO_UT_TYPE (it has problems with AIX headers) * krlogind.c Tidied up the code a bit. Set the controlling tty for Ultrix Do not rely on NO_UT_TYPE (it has problems with AIX headers) Thu Dec 29 10:12:48 1994 Richard Basch (probe@tardis) * krlogind.c Conditionalize grantpt/unlockpt on HAVE_GRANTPT (not just Sun) Conditionalized references to ut_type and ut_pid. Try all the methods for getting a pty... * logutil.c Conditionalized references to ut_type and ut_pid. * configure.in Conditionalize grantpt/unlockpt on HAVE_GRANTPT Corrected a minor syntactical error with extraneous "]," Thu Dec 29 01:38:17 1994 Richard Basch <probe@k9> * krlogind.c: Error checks for Solaris tty setup routines (grantpt/unlockpt) Commented out the OOB code, as it causes problems currently. Cleaned up some of the #ifdef's for logging incoming users Removed extraneous declaration of malloc() Pass a "" for the hostname rather than NULL to update_utmp. Some additional cosmetic changes. Included/excluded SYSV code (SYSV is not defined anywhere) Wed Dec 28 14:59:58 1994 Richard Basch (probe@tardis) * krlogin.c * krlogind.c * krsh.c * krshd.c Corrected the arguments to select, based on sizeof fd_set. Converted what remained to use FD_* macros, instead of bitshift * login.c Changed uid_type to uid_t, gid_type to gid_t Added shadow password support Always use cfset*speed when POSIX_TERMIOS is defined * configure.in Changed the PATH for looking for BSD r* commands Use AC_TRY_LINK instead of AC_TRY_COMPILE for the setenv test. Cache results of compile/link tests. Added shadow password support.

FD_SET) to handle fd arrays Change #ifdef STREAMS to #ifdef HAVE_STREAMS Started to add SYS-V utmp handling Ripped out the old termio code. Include <unistd.h> and <stdlib.h> where available. * configure.in Combined KRB5_UT* macros into CHECK_UTMP, with more checks. Changed obsolete AC_COMPILE_CHECK to use newer macros. Mon Dec 26 13:51:20 1994 Richard Basch (probe@tardis) * Makefile.in * configure.in * krcp.c * krsh.c * krlogin.c Removed the hard-coded paths for the BSD rlogin/rcp/rsh programs. Let "configure" find the programs for us... Mon Dec 19 15:09:57 1994 Theodore Y. Ts'o (tytso@dcl) * krcp.c (des_write): * krlogin.c (des_write): * krlogind.c (v5_des_write): Fix byte swapping code (Missing shift instructions). * krlogind.c (v4_des_read, v4_des_write): Fixed byte swapping code so that V4 des compatibility works on 64 bit architectures. Fri Nov 18 01:19:13 1994 Mark Eichin <eichin@cygnus.com> * Makefile.in (install): add install rules for krlogind.M, krshd.M, rlogin.M, rcp.M, rsh.M. (Section numbers are explicit, and this should probably be changed.) (from Ted Lemon <mellon@ipd.wellsfargo.com> Fri Nov 18 01:10:34 1994 Mark Eichin <eichin@cygnus.com> * configure.in: use new macros KRB5_UTPID, KRB5_UTTYPE, and KRB5_UTHOST (from epeisach). Wed Nov 16 11:45:01 1994 Richard Basch (probe@tardis) * krlogin.c: If the system includes a SA_RESTART signal flag, use it. We want to be able to resume the read() system call after a SIGURG comes. Fri Nov 11 00:53:57 1994 Theodore Y. Ts'o (tytso@dcl) * forward.c (mk_cred, rd_cred): Move mk_cred and rd_cred to libkrb.a. Tue Nov 8 23:52:58 1994 Theodore Y. Ts'o (tytso@dcl) * krshd.c (setpgrp): Defining setpgrp(a,b) to setpgrp() if SETPGRP_TWOARG is not set can cause infinite macro recursion on some C preprocessors. Fix by putting the #ifdef for SETPGRP_TWOARG where setpgrp is actually called, instead of trying to redefine setpgrp(). Mon Nov 7 21:22:00 1994 Theodore Y. Ts'o (tytso@dcl) * configure.in: Add check for stdlib.h * configure.in: Remove unused check for HAVE_GETDTABLESIZE (especially since we replace it with AC_REPLACE_FUNCS later!) * getdtablesize.c: Use POSIX method of obtaining fd table size, if available. Wed Nov 02 22:21:00 1994 Richard Basch (probe@tardis) * configure.in: Moved POSIX signal check to aclocal.m4, and calls it (CHECK_SIGNALS) Added POSIX setjmp check (CHECK_SETJMP). Added checks for waitpid and setsid functions. * kcmd.c: Include <signal.h> not <sys/signal.h>. Don't bother declaring sigmask when POSIX_SIGNALS is set. * krcp.c: Replaced the conditionalized BITS64 code with more portable code. Use mode_t instead of int, for file modes. Use waitpid, instead of wait, where available (HAVE_WAITPID). Added POSIX signal handling (POSIX_SIGNALS). * krlogin.c: Include <unistd.h> and <stdlib.h> if available Replaced the conditionalized BITS64 code with more portable code. Use cfgetospeed() if POSIX_TERMIOS is defined. It was already being used, so there is no need to use two methods. Use waitpid, instead of wait, where available (HAVE_WAITPID). Added POSIX setjmp handling (POSIX_SETJMP) Added POSIX signal handling (POSIX_SIGNALS). * krlogind.c: Added POSIX signal handling (POSIX_SIGNALS). Corrected an error in the arguments to chmod(). Call setsid() if HAVE_SETSID is defined. Try not conditionalizing on __alpha; use other #ifdef's. Replaced the conditionalized BITS64 code with more portable code. * krsh.c: Added POSIX signal handling (POSIX_SIGNALS) * krshd.c: Declare and manipulate the file descriptor arrays properly, rather than bit shifting and passing them to select as (long *). Some systems (eg. AIX) declare them to be structs. Added POSIX signal handling (POSIX_SIGNALS) * login.c: Include <unistd.h> and <stdlib.h> if available Added POSIX setjmp handling (POSIX_SETJMP) Added POSIX signal handling (POSIX_SIGNALS) Use waitpid, instead of wait, where available (HAVE_WAITPID). * logutil.c: Don't redeclare time(); it may conflict with the system header files. Include <unistd.h> first. Thu Oct 27 20:07:03 1994 Mark Eichin (eichin@cygnus.com) * login.c (main): if CSTATUS is missing, don't set c_cc[VSTATUS] (for sunos.) Thu Oct 27 16:12:19 1994 Mark Eichin (eichin@cygnus.com) * krlogin.c (des_write): get rid of srandom, since seeding is done directly in krb5_random_confounder. get rid of unused variables. * krlogind.c (v4_des_write): use krb5_random_confounder directly. get rid of unused variables. Thu Oct 27 14:50:40 1994 Mark Eichin (eichin@cygnus.com) * login.c (main): if CDISCARD is missing, use CFLUSH instead. Thu Oct 27 14:47:41 1994 Mark Eichin (eichin@cygnus.com) * configure.in: fix typo in "use streams interface" test (ttold.h not ttyold.h) Thu Oct 27 14:31:17 1994 Mark Eichin (eichin@cygnus.com) * configure.in: check for srand48, srand, and srandom. * krlogind.c (v4_des_write): use the best available of the three random number systems for padding (based on code from lib/crypto/os/rnd_confoun.c.) Wed Oct 26 00:04:02 1994 Theodore Y. Ts'o (tytso@dcl) * krsh.c (main): * krlogind.c (protocol, v5_des_read): Check for both EAGAIN in addition to EWOULDBLOCK. Mon Oct 24 14:46:07 1994 (tytso@rsx-11) * Makefile.in: The Kerberos V4 libraries must be linked in after the V5 libraries; compat_recvauth pulls in the V4 routines. * kcmd.c (kcmd): Don't free host_save; it's supposed to be returned by kcmd to the caller! * configure.in * krlogin.c (des_write): Don't check for srand48 and then try to define srandom to be srand48. This breaks on machines which have both srandom and srand48. Instead, use krb5_random_confounder; it will do the right thing. Wed Oct 19 12:36:47 1994 Theodore Y. Ts'o (tytso@dcl) * krlogind.c (protocol): Change yet another variable to be an unsigned char. * login.c (main): Add other termios c_cc initializations for the ALPHA. * krlogind.c (protocol): Make protocol buffers be unsigned, since we're comparing against unsigned data. Tue Oct 18 15:48:37 1994 Mark Eichin (eichin@cygnus.com) * configure.in (HAVE_STREAMS): test for streams interface headers in a way that fails on sunos but works on solaris. * krlogin.c: use HAVE_STREAMS. * krlogind.c: use HAVE_STREAMS, fix TIOCPKT_* test. Tue Oct 4 17:14:38 1994 Theodore Y. Ts'o (tytso@dcl) * krcp.c (tgt_keyproc): Add widen.h and narrow.h around declaration so that argument types are widened. Mon Oct 3 13:21:51 1994 Theodore Y. Ts'o (tytso@dcl) * logutil.c (logwtmp): Remove declaration for strncpy(). Fri Sep 30 17:04:24 1994 Theodore Y. Ts'o (tytso@dcl) * krshd.c: Use ifdef for SETPGRP_TWOARG and HAVE_KILLPG * krlogind.c: Use ifdef include of HAVE_SYS_TTY_H and HAVE_SYS_PTYVAR_H (suncc doesn't #define solaris). Thu Sep 29 22:50:05 1994 Theodore Y. Ts'o (tytso@dcl) * Makefile.in: "make clean" should remove the executables * Makefile.in: Relink executables if libraries change Thu Sep 29 17:55:57 1994 Mark Eichin (eichin@tweedledumber.cygnus.com) * krlogin.c (mode): ifdef VLNEXT instead of svr4 for ^V fixing. (doit): ditto. krlogin.c, configure.in: include sys/tty.h and sys/ttold.h only if they're both there. Wed Sep 28 20:57:24 1994 Mark Eichin (eichin@tweedledumber.cygnus.com) * configure.in (srand48): check for srand48, and if it exists, substitute it for srandom (and lrand48 for random.) (K4LIB): add libdes.a, needed for des_pcbc_encrypt. Wed Sep 28 14:36:29 1994 Mark Eichin (eichin@rtl.cygnus.com) * Makefile.in: always put $(K4LIB) before $(KLIB) so that references to libcrypto.a get resolved. Thu Aug 18 18:57:44 1994 Theodore Y. Ts'o (tytso at tsx-11) * Makefile.in: * configure.in: Fix KRB4 handling; do it here in configure.in instead of in Makefile.in Thu Aug 18 18:55:36 1994 Mark Eichin (eichin@perdiem) * configure.in (LOGINLIBS): always substitute it, even if it isn't set. Thu Aug 18 17:09:36 1994 Theodore Y. Ts'o (tytso at tsx-11) * forward.c (get_for_creds): Fix bug to allow cross-realm forwarded credentials to work. * forward.c (rd_and_store_for_creds): Store the forwarded credentials in a file which is PID dependent, to allow for different sessions in an rlogin session. * Makefile: Add $(SETENVOBJ) to all programs that use forward.c Tue Aug 16 22:41:25 1994 Mark Eichin (eichin@cygnus.com) * krlogind.c: add sys/ioctl.h. Tue Aug 16 22:36:29 1994 Mark Eichin (eichin@cygnus.com) * configure.in: set LOGINLIBS to -lodm -ls -lcfg if the system has all three (and is probably an AIX system.) * Makefile.in: use LOGINLIBS for login.krb5. * krshd.c: use HAVE_SYS_SELECT_H. Tue Aug 16 17:58:09 1994 Mark Eichin (eichin@cygnus.com) * krcp.c: check HAVE_VFORK_H * configure.in: use AC_VFORK (runtime test -- consider just using fork instead.) Sat Aug 13 02:04:37 1994 Mark Eichin (eichin@perdiem) * Makefile.in (DEFINES): set LOGIN_PROGRAM correctly. Thu Aug 11 23:16:31 1994 Mark Eichin (eichin@perdiem) * krsh.c: Don't (mis)declare getpwuid ever. Sun Aug 7 04:43:24 1994 Mark Eichin (eichin@cygnus.com) * krlogin.c (oob): FWRITE (and out) not needed w/POSIX_TERMIOS * logutil.c: if EMPTY is missing, use UT_UNKNOWN instead. * login.c (main): some systems just don't have TIOCLSET Fri Aug 5 18:47:00 1994 Mark Eichin (eichin@cygnus.com) * configure.in: test for sigprocmask and sigset_t to set POSIX_SIGNALS. * krlogin.c, kcmd.c: use POSIX_SIGNALS. Fri Aug 5 15:35:54 1994 Mark Eichin (eichin@cygnus.com) * configure.in, logutil.c: check for NO_UT_PID, use it. Wed Jul 27 12:52:04 1994 Mark Eichin (eichin@cygnus.com) * krlogind.c, krlogin.c, krcp.c: define roundup if needed. * Makefile.in: add LIBOBJS, dependency for getdtablesize.o. * getdtablesize.c: new file. * configure.in: build getdtablesize.c if needed. * login.c: HAVE_TTYENT_H. * configure.in: add ttyent.h to HEADERS test. * krshd.c: HAVE_SYS_LABEL_H, which seems to be SunOS 4 specific. * krlogind.c: ditto. * configure.in: test for add sys/label.h to HEADERS test. * krcp.c (rsource): USE_DIRENT_H. * configure.in: test for HAVE_UNISTD_H. * logutil.c: use HAVE_UNISTD_H.

Sat Jul 23 08:48:50 1994 Tom Yu (tlyu@dragons-lair) * kcmd.c: * krshd.c: include ext-proto.h to avoid type warnings Sat Jul 16 02:24:31 1994 Theodore Y. Ts'o (tytso at tsx-11) * kcmd.c: * krsh.c: index->strchr, rindex->strrchr, add (char *) cast to malloc, have proper include for the string functions. Fri Jul 15 15:03:11 1994 Theodore Y. Ts'o (tytso at tsx-11) * krcp.c: add utimes() emulation for systems that only have the POSIX utime() call. Mon Jun 27 22:03:48 1994 Theodore Y.
