path: root/src/kdc/ChangeLog

1999-06-30  Ken Raeburn  <raeburn@mit.edu>

	* Makefile.in (CFLAGS): Define NOCACHE.
	(DEFINES): Commented out, since it's unused.
	* dispatch.c (dispatch): If NOCACHE is defined, don't call
	lookaside buffer code.
	* replay.c: Disable all code if NOCACHE is defined.

1999-06-28  Tom Yu  <tlyu@mit.edu>

	* replay.c (MATCH): Fix up to compare the correct components of
	the input address.

Fri Apr 30 00:05:07 1999  Tom Yu  <tlyu@mit.edu>

	* kerberos_v4.c (kerberos_v4): Fix bug where krb_create_ticket()
	was getting called for an APPL_REQUEST even when there was no
	single-DES key, resulting in random weirdness.

Wed Feb 17 17:07:43 1999  Tom Yu  <tlyu@mit.edu>

	* do_as_req.c (process_as_req): Fix to assign kvno to
	reply.enc_part after encryption, since krb5_c_encrypt() now
	explicitly initializes all fields of a krb5_enc_data.

1998-12-17  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* kdc_preauth.c (check_padata): If preauth fails because the
		preauth data from the client was of an unknown type, and
		the principal does not require preauth, then the preauth
		should be disregarded.  [krb5-kdc/652]

Mon Jan  4 23:50:45 1999  Tom Yu  <tlyu@mit.edu>

	* configure.in (withval): Conditinalize ATHENA_DES3_KLUDGE on
	--enable-athena.

	* main.c (initialize_realms): Kludge to disable
	des3-marc-hmac-sha1 from the command line.

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.)

1998-10-27  Marc Horowitz  <marc@mit.edu>

	* do_as_req.c, do_tgs_req.c, extern.h, kdc_preauth.c, kdc_util.c,
	kerberos_v4.c, main.c: conver to new crypto api.

Fri Sep 25 19:47:26 1998  Tom Yu  <tlyu@mit.edu>

	* kerberos_v4.c (check_princ): Re-order if statements that check
	for null keys to make Purify shut up.

Thu Sep 17 18:21:51 1998  Tom Yu  <tlyu@mit.edu>

	* kdc_util.c (kdc_get_server_key): Fix to not use cached tgs key
	to prevent lossage when it might be out of date by always fetching
	the correct kvno for the ticket out of the database.

Tue Sep  1 19:34:30 1998  Tom Yu  <tlyu@mit.edu>

	* kerberos_v4.c (compat_decrypt_key): Add
 	ENCTYPE_LOCAL_DES3_HMAC_SHA1 to the list of keytypes to bash.
	(kerb_get_principal): Add ENCTYPE_LOCAL_DES3_HMAC_SHA1 to the list
 	of searched enctypes.

Wed Aug 19 13:37:00 1998  Tom Yu  <tlyu@mit.edu>

	* kerberos_v4.c (set_tgtkey): Add kvno arg to fetch an explicit
	kvno.  Also compare kvno as well as realm when caching the TGT
	key.  Declare as static.
	(kerb_get_principal): Add kvno argument to permit searching for
	an explicit kvno.
	(kerberos_v4): Extract the kvno directly out of the krb_req, since
	we know what the format is.

Wed Aug 12 18:40:08 1998  Tom Yu  <tlyu@mit.edu>

	* kerberos_v4.c: Add macro K4KDC_ENCTYPE_OK to determine whether a
	given enctype is compatible with single-DES krb4.
	(compat_decrypt_key): Declare as static.  Change call signature to
	include an output krb5_keyblock as well as an input to determine
	whether the principal should be treated as a service principal.
	Bash the enctype of the keyblock to raw des3 if it's full-blown
	des3.
	(kerb_get_principal): Add k5key and issrv arguments as in
	compat_decrypt_key, mostly to pass them on there.  Hardcode a
	search order that includes des3 for looking up service keys.
	(kerberos_v4): Call krb_create_ticket or krb_cr_tkt_krb5 as
	appropriate to the key type.  While we're at it, s/ktbtgt/krbtgt/
	just to avoid confusing people.
	(check_princ): Add k5key and issrv args for as in
	compat_decrypt_key.  Fix up null key detection to only operate if
	it's a single-des key.
	(set_tgtkey): Call krb_set_key_krb5 if appropriate.

Tue Jul 21 20:29:38 1998  Tom Yu  <tlyu@mit.edu>

	* replay.c (kdc_check_lookaside):
	(kdc_insert_lookaside): Add code to originating address of packet,
 	as krb4 initial ticket requests don't contain an address.  This
 	would cause a subtle problem wherein two simultaneous krb4 initial
 	ticket requests for the same principal originating from different
 	addresses would result in both replies containing the same
	address.

	* kdc_util.h: Modify prototype for lookaside functions.

	* dispatch.c (dispatch): Update to new calling conventions of the
	lookaside functions.

Wed Jul 15 18:32:07 1998  Tom Yu  <tlyu@mit.edu>

	* configure.in: Add CHECK_SIGNALS so that POSIX_SIGNALS gets
	defined.

	* main.c (request_hup): Remove call to signal, as this isn't
	needed on BSD-ish systems and for sysV-ish systems we use
	sigaction anyway.
	(setup_signal_handlers): Fix typo.

Sat Jul 11 01:38:05 1998  Geoffrey King  <gjking@mit.edu>

	* main.c: Added a call to signal() in request_hup()
	        so that the signal handler gets reset after
	        each SIGHUP, since this does not happen
	        automatically in System V's signal handling
	        system.

Wed Jul  8 04:36:28 1998  Geoffrey King  <gjking@mit.edu>

	* extern.h: Added declaration for new variable
	        signal_requests_hup, which is set when the KDC
	        is sent a SIGHUP
	
	* extern.c: Added definition for signal_requests_hup

	* main.c: Added new signal handling code for SIGHUP, including
	        the new function request_hup()

	* network.c: Check signal_requests_hup in the main KDC loop

Fri May  8 18:46:59 1998  Theodore Y. Ts'o  <tytso@mit.edu>

	* kerberos_v4.c (krb4_stime): Print 4 digit years in Krb4 log
	 	entries to avoid Y2K issues.

1998-05-06  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* main.c (initialize_realms): POSIX states that getopt returns -1
		when it is done parsing options, not EOF.

Fri Mar 20 17:13:46 1998  Tom Yu  <tlyu@mit.edu>

	* kdc_util.c (add_to_transited): Check lengths, fix up comma
	quoting somewhat (though things are still way broken).

Fri Feb 20 15:58:21 1998  Theodore Y. Ts'o  <tytso@mit.edu>

	* kdc_preauth.c (get_preauth_hint_list): Don't add the pseudo
		preauth type KRB5_PADATA_PW_SALT to the hint list of
		supported preauthentication systems, since it doesn't help
		to send it.  (And it may screw up Cygnus KerbNet clients.)

Wed Feb 18 16:04:22 1998  Tom Yu  <tlyu@mit.edu>

	* Makefile.in (thisconfigdir): Remove trailing slash.

Mon Feb  2 17:02:29 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* Makefile.in: Define BUILDTOP and thisconfigdir in the Makefile

Thu Feb  5 19:17:25 1998  Tom Yu  <tlyu@mit.edu>

	* kerberos_v4.c: Move macro definition of klog earlier so that it
	actually gets used inside process_v4().

Wed Feb  4 14:15:20 1998  Theodore Y. Ts'o  <tytso@mit.edu>

	* kerberos_v4.c (process_v4): Check the length of the incoming V4
		packet before copying it into the KTEXT_ST variable.
		(kerberos_v4): Make sure the strings in the V4 request
		structures aren't no longer than they are allowed to be.

Wed Jan 28 08:56:07 1998  Ezra Peisach  <epeisach@mit.edu>

	* krb5kdc.M: Document V4 mode handling [krb5-kdc/464].

Wed Jan 21 15:15:58 1998  Ezra Peisach  <epeisach@mit.edu>

	* rtest.c (main): returns int, not void. ANSI X3.159-1989
	2.1.2.2.1 says so, and gcc now warns about it.

Fri Jan 16 03:33:50 1998  Tom Yu  <tlyu@mit.edu>

	* do_tgs_req.c: Add some explicit settings of errcode so that the
 	cleanup code doesn't try to construct a bogus error reply, which
 	was causing coredumps in the lookaside code.

Thu Dec 11 23:29:41 1997  Tom Yu  <tlyu@mit.edu>

	* kerberos_v4.c: Don't include sys/socket.h or netdb.h, as krb.h
	already gets those and Ultrix doesn't protect them against
	multiple inclusion.

Mon Nov 24 19:57:48 1997  Theodore Y. Ts'o  <tytso@mit.edu>

	* do_tgs_req.c (process_tgs_req): Add check to make sure cname and
		sname are non-NULL when syslogging an error because the
		principals don't match.
	
	* kdc_util.c (limit_string): Check to make sure the input string
		is non-NULL before operating on it.

Thu Nov 13 20:40:01 1997  Theodore Y. Ts'o  <tytso@mit.edu>

	* do_tgs_req.c (process_tgs_req): Only try to return a TGT for a
		"closer" realm if the request was for a TGT in the first
		place.  [krb5-kdc/459]

Wed Nov 12 14:47:46 1997  Ezra Peisach  <epeisach@mit.edu>

	* do_as_req.c (process_as_req): Reset master key after closing and
 	 	reopening DB when KDC_UPDATES_KDB compiled
 	 	in. [krb5-kdc/495 by Tony Mione]

Mon Nov 10 20:03:14 1997  Theodore Y. Ts'o  <tytso@mit.edu>

	* kdc_util.c (kdc_process_tgs_req): If not using the reply cache,
		properly handle a failure return from
		krb5_rd_req_decode_anyflag().

Wed Oct  8 12:20:35 1997  Ezra Peisach  <epeisach@kangaroo.mit.edu>

	* main.c (main): Initialize kdc error table with
	        initialize_kdc_error_table().

Thu Sep 25 21:19:08 1997  Tom Yu  <tlyu@mit.edu>

	* network.c: Replace KRB5_USE_IENT with something more sane.

	* do_tgs_req.c: Replace KRB5_USE_INET with something more sane.

	* main.c: Replace KRB5_USE_INET with something more sane.

	* do_as_req.c: Replace KRB5_USE_INET with something more sane.

Wed Sep 24 11:56:50 1997  Ezra Peisach  <epeisach@kangaroo.mit.edu>

	* kdc_util.c (add_to_transited): Fix up memory leaks, clean out
        new memory allocated, allocate buffers to max size
        needed. [based on krb5-kdc/461 by Ken Hornstein].

	* rtest.c: Rewrite code to use context and current krb5_principal
	        structure.

	* configure.in: Add KRB5_RUN_FLAGS

	* Makefile.in (rtest): Compile rtest and run during make check.


Tue Sep 23 13:25:35 1997  Ezra Peisach  <epeisach@kangaroo.mit.edu>

	* kerberos_v4.c (check_princ): Add checks for V5 kdc flags
	        including REQUIRES_PWCHANGE, DISALLOW_ALL_TIX,
	        REQUIRES_PREAUTH. Adds support for parsing the V4 options.
		[krb5-kdc/464].

	* main.c (main): Add option -4 to specify V4 handling mode.

Mon Aug 18 12:29:08 1997  Ezra Peisach  <epeisach@mit.edu>

	* do_tgs_req.c (process_tgs_req): Initialize authtime to 0 so it
        is set before potentially used in case the packet has an error.

	* kdc_preauth.c (get_sam_edata): Remove unused variables.

	* kdc_util.h: Added prototype for setup_server_realm().

	* main.c (get_realm_port): Removed unused function.
	         (setup_server_realm): Moved prototype to kdc_util.h

Wed Jul 30 18:29:19 1997  Tom Yu  <tlyu@mit.edu>

	* kdc_util.c: 
	* main.c: Don't use an rcache.

Fri Jul 25 15:44:07 1997  Tom Yu  <tlyu@mit.edu>

	* main.c (init_realm): Fix to use new ktkdb.

Tue Jul 15 01:55:56 1997  Tom Yu  <tlyu@mit.edu>

	* kdc_preauth.c (get_sam_edata): Don't goto cleanup if SAM is not
	used; this prevents freeing an unallocated keyblock.

Thu May 29 21:08:24 1997  Theodore Y. Ts'o  <tytso@mit.edu>

	* do_as_req.c (process_as_req), do_tgs_req (process_tgs_req): Use
		limit_string() to make sure the length of cname and sname
		are reasonable.

	* kdc_util.c (limit_string): New function which limits the strings
		that will end up in log files to "reasonable" lengths.

Tue Feb 18 09:56:16 1997  Ezra Peisach  <epeisach@mit.edu>

	* kerberos_v4.c: Remove include of krb4-proto.h

Tue Feb 18 18:51:09 1997  Richard Basch  <basch@lehman.com>

	* do_as_req.c do_tgs_req.c kdc_preauth.c kdc_util.c main.c
	replay.c kerberos_v4.c:
		Replace krb5_xfree with appropriate free routine.

Thu Feb  6 00:09:46 1997  Richard Basch  <basch@lehman.com>

	* Makefile.in: Remove logger.c target before copying over it.
		This avoids permission problems if the source is read-only
		and later changes.

Wed Jan  1 22:56:16 1997  Ezra Peisach  <epeisach@mit.edu>

	* kdc_preauth.c (get_sam_edata): Use proper interface to
		krb5_db_get_principal. Also if SAM is not an option, do
		not return as a possible type to client. [krb5-kdc/310]

Fri Jan 31 21:39:04 1997  Ezra Peisach  <epeisach@mit.edu>

	* Makefile.in (LOCALINCLUDE): Change  KRB4_INCLUDE to KRB4_INCLUDES

Fri Jan 31 19:45:13 1997  Tom Yu  <tlyu@mit.edu>

	* Makefile.in:
	* configure.in: Update to new program build procedure.

Sat Nov 23 17:26:22 1996  Mark Eichin  <eichin@kitten.gen.ma.us>

	* [krb5-libs/149] only generate requests that you can actually
	handle.
	
	Tue Sep  3 22:53:56 1996  Mark Eichin  <eichin@cygnus.com>

	* kdc_preauth.c (get_preauth_hint_list): detect ap->get_edata
	return status and don't pass back hint if it failed.
	(get_etype_info): malloc one more word in entry for end marker.

Wed Nov 20 11:25:05 1996  Barry Jaspan  <bjaspan@mit.edu>

	* main.c (initialize_realms): krb5_aprof_init can succeed while
 	leaving aprof == NULL, but krb5_aprof_finish will fail.  This is
 	just more grossness that needs to be redone when the kdc.conf
 	interface is reworked.

Thu Nov  7 12:27:21 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* kdc_preauth.c (check_padata): Fixed error handling; in order for
		check_preauth to return successfully, there must be at
		least one preauth which succeeded, and no REQUIRED preauth
		system which failed.  If a preauth is marked SUFFICIENT,
		then the rest of the preauth list aren't checked.  Fixed
		bug where when none of the preauth types were recognized,
		an error message corresponding to stack garbage was printed.

Wed Nov  6 12:00:48 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>

	* main.c (argv): Check the error return from krb5_init_context(),
 		and print an error message if necessary.

Mon Nov  4 22:29:30 1996  Theodore Y. Ts'o  <tytso@mit.edu>

	* main.c (initialize_realms): Remove rather pointless use of
 		krb5.conf to find the kdc.conf used to get the default
 		port list.  It's not useful for anything else, and will
		just confuse people.
		(init_realm): Reformat function to be readable.  Add error
		checking to call of krb5_read_realm_params

Wed Sep 18 16:03:26 1996  Theodore Y. Ts'o  <tytso@mit.edu>

	* kdc_util.c: Added magic number to initializer of nolrentry.

Tue Sep 10 14:18:41 1996  Tom Yu  <tlyu@mit.edu>

	* krb5kdc.M: remove ".so man1/header.doc"

Fri Aug 23 14:22:45 1996  Sam Hartman  <hartmans@tertius.mit.edu>

	* kerberos_v4.c (check_princ): Assume an expiration date of zero means never expire.

Thu Aug  1 11:13:46 1996  Ezra Peisach  <epeisach@dumpster.rose.brandeis.edu>

	* configure.in (withval): Link -ldyn as it is needed by the kadm5
		shared library.  

Wed Jul 24 02:29:19 1996  Sam Hartman  <hartmans@mit.edu>

	* kerberos_v4.c (set_tgtkey): s/KRB4_#@/krb5_ui_4 so we work with
 	athena Kerberos.



Tue Jul 23 22:26:29 1996  Theodore Y. Ts'o  <tytso@mit.edu>

	* Makefile.in: Build logger.o from the libkadm5 directory.  This
 		is prepatory work towards eliminating the dependency on
 		libkadm5.  Ultimately we will probably need to rethink how
		the library structure for krb5....

	* configure.in: Add -lgssapi and -lgssrpc to libraries linked with
 		krb5kdc since they are needed for shared libraries.  This
 		is a horrible hack....


Thu Jun 13 22:09:34 1996  Tom Yu  <tlyu@voltage-multiplier.mit.edu>

	* configure.in: remove ref to ET_RULES

Sun Jun  9 23:03:06 1996  Ezra Peisach  <epeisach@kangaroo.mit.edu>

	* main.c (finish_realm): Do not invoke krb5_finish_key if
		encryption block is not set.

Sun May 12 01:17:05 1996  Marc Horowitz  <marc@mit.edu>

	* configure.in: USE_KADM_LIBRARY replaced by USE_KADMSRV_LIBRARY

Tue May  7 18:19:59 1996  Ken Raeburn  <raeburn@cygnus.com>

	Thu May  2 22:52:56 1996  Mark Eichin  <eichin@cygnus.com>

	* kdc_util.c (kdc_process_tgs_req): call
	krb5_rd_req_decoded_anyflag instead of krb5_rd_req_decoded, so
	that invalid tickets can be used to validate themselves. Add
	explicit check that if the ticket is TKT_FLG_INVALID, then
	KDC_OPT_VALIDATE was requested.

Mon May  6 12:15:36 1996  Richard Basch  <basch@lehman.com>

	* main.c: Fixed various abstraction violations where the code knew
	the internals of eblock->crypto_entry.

Wed Feb 28 13:07:28 1996  Ezra Peisach  <epeisach@kangaroo.mit.edu>

	* main.c: Move com_err.h after k5-int.h include.

Tue Feb 27 17:33:44 1996  Richard Basch  <basch@lehman.com>

	* main.c:
	Do not repeat random number generator initializations, as memory
	is allocated and never reclaimed.  Also fixed the V4 random number
	generator initialization (a DES_CBC_CRC random number is generated
	and used as a seed for the V4 routine, but the generation function
	was being called with the wrong arguments).

	* do_as_req.c:
	Memory was occassionally being freed twice because the pointer was
	not re-initialized to NULL after it was freed.

Sun Feb 25 16:04:10 1996  Mark W. Eichin  <eichin@cygnus.com>

	* main.c (initialize_realms): missing indirection for conf_val in
	alternate profile code. (This should really be in a library...)

Sat Feb  3 22:37:55 1996  Mark Eichin  <eichin@cygnus.com>

	* network.c (add_port): sunos realloc doesn't handle a NULL
	pointer, so protect with a macro.

Sat Feb 10 02:46:27 1996  Mark Eichin  <eichin@cygnus.com>

	* main.c (initialize_realms): look for [kdc] profile=path for
	default alternate kdc profile (environment variable still
	overrides it.)

Wed Feb 21 23:28:33 1996  Richard Basch  <basch@lehman.com>

	* kerberos_v4.c: Improve checking of DES keys

	* main.c: Do not assume the master key is DES; instead initialize
		the V4 random key generator from a random key after the
		DES_CBC_CRC generator has been initialized.

Tue Feb 20 16:50:59 1996  Theodore Y. Ts'o  <tytso@dcl>

	* kerberos_v4.c (kerberos_v4): Use strong random number generator

	* main.c (main): Initialize Kerberos V4's random number generator.

Sat Jan 27 00:53:41 1996  Mark Eichin  <eichin@cygnus.com>

	* network.c (setup_network): strtol is good enough for port
	number, and sunos doesn't have strtoul (and nothing else in the
	tree uses it.)
	(add_port): use proper old-style definition.
	
Wed Dec 13 03:51:53 1995  Chris Provenzano (proven@mit.edu)

        * kerberos_v4.c : Remove mkvno for krb5_db_entry

Tue Dec 12 01:10:34 1995  Chris Provenzano (proven@mit.edu)

	* extern.h: Added a krb5_keytab to the realm context. The keytab
		should be associated with a krb5_db_context which will
		make having a krb5_context unnecessary in the realm context.
	* kdc_util.c kdc_process_tgs_req(): Use the realm keytab instead
		of faking up a user-to-user key to pass to krb5_rd_req_decode().
	* main.c: Added code to use the new database keytab routines.

Mon Dec 11 16:58:31 1995  Chris Provenzano (proven@mit.edu)

	* kdc_preauth.c return_padata(): Initialize local variable "size" 
		to 0 before using it.

Thu Nov 30 20:57:11 1995  Tom Yu  <tlyu@dragons-lair.MIT.EDU>

	* kdc_preauth.c: #@&^(!! Ultrix cc sucks.  Typedef to function
		pointer rather than function prototype to avoid lossage.

Wed Nov 29 13:31:39 1995  Theodore Y. Ts'o  <tytso@dcl>

	* do_tgs_req.c (process_tgs_req): Removed extra eblock argument
		from call to krb5_encode_kdc_rep.

Fri Nov 17 22:41:37 1995  Theodore Y. Ts'o  <tytso@dcl>

	* do_as_req.c (process_as_req): Removed extra eblock argument from
		call to krb5_encode_kdc_rep.

Mon Nov 13 19:40:50 1995  Theodore Y. Ts'o  <tytso@dcl>

	* kdc_util.h: Added new prototypes for return_padata() and
	        check_padata().

	* kdc_preauth.c (return_padata): New function which calls out to
		each preauth type to see if it is necessary to return
		preauth data or not.
	(return_pw_salt): New function responsible for returning the
		KRB5_PW_SALT preauth information.

	* do_as_req.c (process_as_req):  Move creation of the PW_SALT
		preauthentication step into kdc_preauth.c.  Call
		return_pdata() which is responsible for all padata info
		which is returned by the KDC in the KRB_AS_REP message.

		function so that the e_data field may be passed in and
		included in the KRB_ERROR messsage which is passed back to
		the user.

Mon Aug 21 17:03:53 EDT 1995	Paul Park	(pjpark@mit.edu)

		key instead of using the key in slot 0.  Fix gcc -Wall moans.
	* kdc_util.c - Use per-realm key/salt list to determine which key to
		use from the list of server keys.  Fix gcc -Wall complaints.
	* kerberos_v4.c - Use krb5_dbe_find_keytype() to find appropriate key.

		alt_prof.c because it's now used by admin and kadmin programs.
		Remove explicit stash file handling logic and supply stash

		non-default stash file name.

Thu Jul 13 19:51:33 1995  Sam Hartman  <hartmans@tertius.mit.edu>

	* main.c: Include netinet/in.h if we're using IP.

		from network.c.  Add -s flag and change meaning of -p flag to
		be the default if none specified in KDC or Kerberos profile.

Thu Jun 29 06:50:08 1995  Mark Eichin  <eichin@cygnus.com>

	* kerberos_v4.c (check_princ): delete master_key_version check,
	since we never actually set it.
	(main): elide original V4 server code to avoid confusion when
	looking for variable references.
	(type_2_v5err): reformat for 79 columns instead of 80 and
	conditionalize out since it is unused (though still informative.)

		is to avoid having to rewrite everything to pass a pointer to
		the active realm.
	* kdc_util.c - Change "kdc_context" to "kcontext" because of #defines
		in extern.h.  Also add logic after call to rd_req_decoded
		to see if it failed because of a rcache error.  If so, then
		reinitialize the replay cache and retry it.
		Also change KDB_CONVERT_KEY_OUTOF_DB to decrypt_key.
	* kerberos_v4.c - Remove extraneous definition of master_encblock.
	* krb5kdc.M - Add definition of -p, add vague reference to kdc.conf
		manpage and describe multiple realms briefly.

                split out.
	* configure.in - Remove dbm library checks, these are no longer needed
		with the Berkeley database code.  Also, add shared library
		usage check.

Tue Jun 13 12:44:20 1995  Sam Hartman  <hartmans@tardis.MIT.EDU>

	* network.c: Base inclusion of sys/select.h on whether it exists

Fri Mar 24 14:58:07 1995    <tytso@rsx-11.mit.edu>

	* replay.c: The KDC replay cache needs to store the database
		modification time, so that if the database is modified in
		between when it receives a request and when it receives a
		replay of the same request, it knows to throw away the
		replay cache entry and generate a new response (since the
		record in the database on which the response is based may
		have been modified).

Fri Feb 10 14:35:42 1995  Theodore Y. Ts'o  <tytso@dcl>

	* do_tgs_req.c (process_tgs_req): krb5_use_keytype() was being
		called when the argument was a encryption type.   Change
		use to krb5_use_cstype().  Actually, any use of

		ticket; it will be freed as part of other structures.

	* do_tgs_req.c (process_tgs_req): Set the encryption type in the
		reply structure, and set the eblock type accordingly.

Wed Dec  7 13:36:34 1994    <tytso@rsx-11.mit.edu>

	* do_as_req.c (process_as_req): Use the list of encryption types
		passed as part of the KDC request to determine which
		encryption to use for encrypting the ticket.  The
		encryption must be one that is supported by the KDC, as
		well as being one which is marked as being supported by
		the server of the ticket.  In a AS request, also use this
		encryption for encrypting the KDC response.  In a TGS
		request, use the encryption type of the TGT authenticator
		to determine how to encrypt the KDC response. 

Tue Nov  8 17:51:30 1994  Theodore Y. Ts'o  (tytso@dcl)

	* do_tgs_req.c (process_tgs_req): Use published interface to call

Wed Sep 21 17:40:56 1994  Theodore Y. Ts'o  (tytso@dcl)

	* kdc_util.c, kdc_util.h (realm_compare): Change realm_compare so
		that both arguments are principals.  This makes it less
		confusing....

	* kdc_util.c (add_to_transited): Folded in Tony Andrea's changes
		so that add_to_transited doesn't assume that the contents
		of a krb5_data->data are null terminated.

	* do_tgs_req.c (process_tgs_req): Add the realm of the presented
	  tgt if it is different from the local realm (cross-realm) and it
	  is different than the realm of the client (since the realm of
	  the client is already implicitly part of the transited list and
	  should not be explicitly listed).

	* Makefile.in: Move optional link with $(KRB4)/lib/libdes.a to

	defined.
