1 Wed Apr 5 16:41:41 1995 Keith Vetter (keithv@fusion.com)
3 * los-proto.h, func-proto.h: moved krb5_us_timeofday and
4 krb5_sname_to_principal from the former to the latter.
5 * base-def.h: added FAR to pointer types for the PC.
6 * func-proto.h: added FAR to pointer types in prototypes but
7 only for functions which are exported.
9 Fri Mar 31 19:34:47 1995 Keith Vetter (keithv@fusion.com)
11 * k5-config.h: defined dup to _dup for STDC stuff on Windows
13 Fri Mar 31 16:12:28 1995 Theodore Y. Ts'o (tytso@dcl)
15 * configure.in (CONFIG_RULES): Replaced.
17 Thu Mar 30 15:57:22 1995 Keith Vetter (keithv@fusion.com)
19 * func-proto.h: added 2 missing prototypes dealing with auth_con.
21 Tue Mar 28 19:53:09 1995 Keith Vetter (keithv@fusion.com)
23 * Makefile.in: changed to reflect deletion of stock/osconf.win.
24 * k5-config.h: added constants for reading default values
25 out of Windows ini files.
26 * los-proto.h: added new prototype for Windows ini stuff.
28 Tue Mar 28 18:02:41 1995 John Gilmore (gnu at toad.com)
30 * Makefile.in (KRB5_HEADERS, install): Account for file renames.
32 * configure.in (CONFIG_RULES): Remove.
33 (krb5_sigtype): Define as either void or int.
34 * encryption.h: Insert parentheses in macros to avoid mis-expansion.
35 * k5-config.h: Further parameterize socket support.
36 * macsock.h: Support connect(), recv(), send(), getmyipaddr().
37 (WSAGetLastError): Fix typo -- there's no argument to this macro.
39 * k5-errors.h: Rename errors.h (which duplicated a standard Mac
40 header name, causing a problem).
41 * AddressXlation.h, GetMyIPAddr.h, MacTCPCommonTypes.h, TCPPB.h,
42 UDPPB.h: Add MacTCP header files.
44 Mon Mar 27 09:33:10 1995 Chris Provenzano (proven@mit.edu)
46 * func-proto.h (krb5_rd_req(), krb5_rd_req_decode(), krb5_mk_rep(),
47 krb5_recvauth(), and krb5_compat_recvauth(). Added a
48 krb5_auth_context argument and eliminated many of the
49 other arguments because they are included in the
50 krb5_auth_context structure.
52 Fri Mar 24 14:15:51 1995 <tytso@rsx-11.mit.edu>
54 * adm_defs.h (ADM5_DEFAULT_PORT): Add definition of default
57 * Makefile.in (install): Delete the destination header files
58 before copying in the new ones. Also install autoconf.h.
59 Only install header files if the header file has changed.
61 Wed Mar 22 11:37:24 1995 Keith Vetter (keithv@fusion.com)
63 * k5-config.h: added HAVE_SYS_TYPES_H. Cleaned up the loading
64 of sys/types.h which john added earlier. Specifically, we always
65 have it and it's missing some typedefs used by this code.
67 Tue Mar 21 18:42:23 1995 Keith Vetter (keithv@fusion.com)
69 * k5-config.h: PC: NO_PASSWORD defined and files opened in binary mode.
70 * func-proto.h: added new prototype for notify programs when the
71 ccache changes, and moved krb5_get_default_realm from los-proto.h.
72 * los-proto.h: moved krb5_get_default_realm into func-proto.h.
74 Sun Mar 19 12:51:59 1995 John Gilmore (gnu at toad.com)
76 * base-defs.h: Fix comment that referred to STDARG_PROTOTYPES.
78 Fri Mar 17 19:12:13 1995 John Gilmore (gnu at toad.com)
80 * k5-config.h: Move <sys/types.h> handling from ../krb5.h to
81 here, because we need <sys/types.h> or the u_* types to be defined
82 before we include the Unix socket include files a little later in
83 k5-config.h. We actually add this code twice, once in the MSDOS
84 section and once in the Unix/Mac section.
85 (NEED_SOCKETS): Also include <net/if.h>, for localaddr.c.
86 * Makefile.in (clean-mac): Add.
88 Tue Mar 14 16:50:54 1995 <tytso@rsx-11.mit.edu>
90 * Makefile.in: Delete definition for KRB5ROOT and KRB5_INCDIR,
91 since those are defined in pre/config.in.
93 Thu Mar 16 20:58:22 1995 John Gilmore (gnu at toad.com)
95 * configure.in: Replace nonstandard CHECK_STDARG with
96 AC_CHECK_HEADERS. Also check for header file macsock.h, which
97 is a dummy test -- it's false on Unix and PC's, but on the Mac
98 we hand-configure it to be true, to indicate that we want Mac
99 socket support rather than Unix socket support.
100 * base-defs.h, k5-config.h: Use HAVE_STDARG_H, not STDARG_PROTOTYPES.
101 * k5-config.h (NEED_SOCKETS): Add new section which brings in
102 socket include files for the appropriate compilation environment
103 (Mac or Unix; Windows already did this).
104 * macsock.h: New include file, derived from Cygnus Network Security
105 Mac K4 release, for simulating sockets under MacTCP.
107 Thu Mar 16 12:12:17 1995 Keith Vetter (keithv@fusion.com)
109 * k5-config.h: PC change, getting sys_nerr and sys_errlist to work.
111 Tue Mar 14 17:38:28 1995 Keith Vetter (keithv@fusion.com)
113 * k5-config.h: more PC changes, mostly dealing with chmod not
114 working as it should on the PC.
115 * func-proto.h, los-proto.h: moved prototypes for krb5_timeofday and
116 krb5_os_localaddr from los-proto to func-proto. They are needed by
117 the outside world, specifically kinit.c
119 Fri Mar 10 14:23:12 1995 Theodore Y. Ts'o <tytso@dcl>
121 * sysincl.h: Removed definition of FD_SETSIZE, FD_SET, FD_CLR,
122 FD_ISSET, and FD_ZERO. Defining them in favor of using
123 the system include files is almost always wrong.
125 Fri Mar 10 10:04:41 1995 Chris Provenzano (proven@mit.edu)
127 * func-proto.h (krb5_mk_req(), krb5_mk_req_extended(), krb5_rd_rep(),
128 krb5_sendauth(), krb5_mk_priv(), krb5_rd_priv(), krb5_mk_safe(),
129 and krb5_rd_safe()). Added a krb5_auth_context argument and
130 eliminated many of the other arguments because they are
131 included in the krb5_auth_context structure.
133 * fieldbits.h Added #define AP_OPTS_USE_SUBKEY 0x00000001 for a
134 new option to an ap req message. This is mainly a clean way
135 to inform krb5_mk_req() and krb5_mk_req_extended() to
136 create the subkey without adding an extra argument.
138 * safepriv.h Replace safe/priv flags with flags for krb5_auth_context
139 and add krb5_replay_data structure for when the appilication
140 want to do it's own replay detection for safe and priv calls.
143 Thu Mar 9 18:29:24 1995 Mark Eichin <eichin@cygnus.com>
145 * Makefile.in (all-windows): tabs, not spaces.
147 Tue Mar 7 14:54:02 1995 Keith Vetter (keithv@fusion.com)
149 * ccache.h: added windows INTERFACE keyword to all functions.
150 * encryption.h: more segment games for the PC--added NEAR to three
151 external data objects.
152 * wordsize.h: added constants VALID_INT_BTIS and VALID_UINT_BITS for
153 detecting overflow when casting a long to an int.
154 * k5-config.h: numerous PC changes such as adding NEED_LOWLEVEL_IO
155 which enables the read/write level of I/O.
156 * Makefile.in: osconf.h now pulled in from stock/osconf.win.
158 Thu Mar 2 23:21:46 1995 John Gilmore (gnu at toad.com)
160 Make include files start to work on the Macintosh.
162 * configure.in: Add checks for sys/types.h and sys/stat.h.
163 * k5-config.h: Remove krb5/ from #include.
164 * sysincl.h: Avoid <sys/types.h>. Conditional-include <sys/stat.h>.
166 Thu Mar 2 13:30:00 1995 Keith Vetter (keithv@fusion.com)
168 * k5-config.h: changed NEED_WINSOCK_H to NEED_SOCKETS
170 Wed Mar 1 20:00:00 1995 Keith Vetter (keithv@fusion.com)
172 * func-proto.h: fixed up a const attribute to krb5_send_tgs.
174 Wed Mar 1 17:40:00 1995 Keith Vetter (keithv@fusion.com)
176 * func-proto.h: added missing prototype for krb5_mk_cred.
177 * los-proto.h: added windows INTERFACE keyword to all functions,
178 plus added 2 missing prototypes: krb5_os_init_context and
179 krb5_os_free_context.
181 Wed Mar 1 12:48:20 1995 Keith Vetter (keithv@fusion.com)
183 * config.h: added defines to pull in winsock.h as needed
184 * rcache.h: added windows INTERFACE keyword to all functions
185 * winsock.h: new file--for windows socket stuff
187 Wed Mar 1 17:45:13 1995 Theodore Y. Ts'o <tytso@dcl>
189 * configure.in, k5-config.h: Only define labs(x) -> abs(x) if
190 labs() is not defined elsewhere. (This really shouldn't
191 be here at all, but is the expedient way to deal with lack
194 * Makefile.in: Change config.h -> k5-config.h and free.h ->
195 k5-free.h to reflect renamed header files for Mac/PC port.
197 Mon Feb 27 23:47:58 1995 John Gilmore (gnu at toad.com)
199 * Makefile.in (osconf.h): Remove temp file osconf.new.
201 * krb5.h: Rename to ../krb5.h so it can be #included by end users
202 without the use of slashes or extra -I options. First step in
203 making it stand alone without a train of a dozen other include
204 files tagging along behind.
206 * base-defs.h, dbm.h, error_def.h, sysincl.h: Avoid #include
207 <krb5/...> form; use "..." form.
209 * config.h: Rename to k5-config.h. This is too common a
210 name, now that we use -I..../include/krb5.
211 * free.h: Rename to k5-free.h.
213 * configure.in (AC_INIT): Use another file (not krb5.h) as src test.
215 Mon Feb 27 11:35:49 1995 Keith Vetter (keithv@fusion.com)
217 * config.h: added windows interface keyword for varargs functions,
218 added defines to allows <windows.h> to be stdc compliant.
219 * func-proto.h: added windows INTERFACE_C keyword for functions
220 with varargs, and fixed const in prototype for krb5_send_tgs.
221 * preauth.h: added windows INTERFACE keyword to prototypes
223 Wed Feb 22 17:39:46 1995 Chris Provenzano (proven@mit.edu)
225 * func-proto.h (krb5_get_credentials(), krb5_get_cred_from_kdc(),
226 and krb5_sendauth()) replaced krb5_cred * IN/OUT arg with
227 a krb5_cred * IN and a krb5_cred ** OUT arg.
228 * func-proto.h (krb5_mk_req_extended()) Remove kdc_options flag arg
229 and krb5_ccache arg. They are no longer necessary.
231 Wed Feb 22 01:45:17 1995 Keith Vetter (keithv@fusion.com)
233 * keytab.h: added windows INTERFACE keyword to prototypes
235 Tue Feb 21 17:31:06 1995 Keith Vetter (keithv@fusion.com)
237 * config.h: added HAVE_ERRNO for the windows section
238 changed windows manifest constant from __windows__
239 to _MSDOS so that DOS test programs will compile.
241 Tue Feb 21 12:00:32 1995 Keith Vetter (keithv@fusion.com)
243 * asn1.h: added windows INTERFACE keyword to all functions.
245 Tue Feb 21 17:49:41 1995 Mark Eichin (eichin@cygnus.com)
247 * config.h: get krb5/autoconf.h.
248 * Makefile.in (KRB5_HEADERS): add config.h, remove rsa-md4.h and
249 crc-32.h which aren't here anymore.
251 Tue Feb 21 0:0:32 1995 Keith Vetter (keithv@fusion.com)
253 * func-proto.h: added windows INTERFACE keyword to all functions.
254 * krb5.h: moved two typedefs before inclusion of func-proto.h
256 Mon Feb 20 16:54:51 1995 Keith Vetter (keithv@fusion.com)
258 * encryption.h, los-proto.h, rsa-md5.h: added windows
260 * Makefile.in: removed isode cruft ala Feb 10 changes but for windows
262 Mon Feb 20 12:32:34 1995 John Gilmore (gnu at toad.com)
264 * configure.in: Flip again. Use AC_CHECK_HEADERS, but default the
265 symbol-setting. This is Modern Autoconf Style.
267 * config.h: Create from stock/config.h and stock/config.win.
268 * Makefile.in (BUILT_HEADERS): Remove config.h.
269 (CONF_REPLACE, CONFSRC, config.h rule): Remove. Config.h is
270 a static header file, ever since imake died. Now it really is.
271 (clean): Don't remove config.new any more.
273 Thu Feb 16 20:12:23 1995 John Gilmore (gnu at toad.com)
275 * configure.in: Use AC_HAVE_HEADER rather than AC_HEADER_CHECK.
276 (Fixes resulting #define names to HAVE_XXX rather than HAS_XXX,
277 which is not only consistent but also matches what's in sysincl.h.)
279 Mon Feb 6 19:42:7 1995 Keith Vetter (keithv@fusion.com)
281 * configure.in: added header checks for sys/param.h and sys/file.h.
282 * encryption.h: added typedef prototype for sum_func function
283 with the windows api to make microsoft compiler happy.
284 * sysincl.h: conditionally include sys/file.h and sys/param.h since
285 windows doesn't have them.
287 - changed macros with ${...} to $(...) since nmake barfs on {}.
288 - added windows only make preamble
289 - split the all target into unix and windows branches
291 Fri Feb 10 14:54:26 1995 Theodore Y. Ts'o <tytso@dcl>
293 * asn1.h: Removed ISODE cruft -- moved included .h files into
294 asn1.h, to simplify the krb5 header file structure.
296 * Makefile.in (ET_HEADERS): Remove isode cruft.
298 Mon Feb 06 17:19:04 1995 Chris Provenzano (proven@mit.edu)
300 * func-proto.h (krb5_get_in_tkt()) Changed key_proc args to be the
301 following (krb5_context, const krb5_keytype, krb5_data *,
302 krb5_const_pointer, krb5_keyblock **)
304 * func-proto.h (krb5_get_in_tkt_*()) Removed krb5_keytype, changed
305 krb5_enctype to krb5_enctype *, changed krb5_preauthtype to
308 * func-proto.h Added new routine krb5_get_in_tkt_with_keytab().
310 Fri Feb 3 07:57:31 1995 Theodore Y. Ts'o (tytso@dcl)
312 * configure.in: Use politically correct name of AC_CHECK_SIZEOF
313 instead of AC_SIZEOF_TYPE.
316 * wordsize.h: Don't use BITS16, BITS32, etc. anymore. Use
317 autoconf's SIZEOF_INT and SIZEOF_LONG definitions to make
320 Mon Jan 30 15:43:19 1995 Chris Provenzano (proven@mit.edu)
322 * func-proto.h Added krb5_keytype arg to rb5_rdreq_key_proc.
324 * func-proto.h (krb5_send_tgs()) Changed krb5_enctype arg to
325 krb5_enctype *, a NULL terminated array of encryption types.
327 * func-proto.h Added prototypes for krb5_get_for_creds(),
328 krb5_set_default_in_tkt_etypes(), and
329 krb5_get_default_in_tkt_etypes().
331 * krb5.h Added fields to krb5_context to support default etypes.
333 Fri Jan 27 00:56:12 1995 Chris Provenzano (proven@mit.edu)
335 * func-proto.h (krb5_kt_read_service_key()) Added krb5_keytype arg.
336 * keytab.h (krb5_kt_get_entry()) Add krb5_keytype arg.
338 Fri Jan 27 00:56:12 1995 Chris Provenzano (proven@mit.edu)
340 * base-defs.h Typedef krb5_boolean, krb5_msgtype, krb5_kvno,
341 krb5_addrtype, krb5_keytyp, krb5_enctype, krb5_cksumtype,
342 and krb5_authdatatype as unsigned int.
343 * kdb_dbm.h krb5_dbm_db_set_lockmode(), krb5_dbm_db_set_nonblocking()
344 Fix prototypes to use krb5_boolean and not int.
345 * kdb.h krb5_db_set_lockmode(), krb5_db_set_nonblocking()
346 Fix prototypes to use krb5_boolean and not int.
348 Wed Jan 25 19:26:57 1995 John Gilmore (gnu at toad.com)
350 * crc-32.h: Move to lib/crypto/crc32; only gets local use.
351 * rsa-md4.h: Move to lib/crypto/md4; only gets local use.
353 Wed Jan 25 20:01:36 1995 Mark Eichin (eichin@cygnus.com)
355 * configure.in: rewrote remaining tests to use AC_TRY_COMPILE and
356 caching. Added cross-compile case for ANSI stdio test.
358 Wed Jan 25 17:50:35 1995 Chris Provenzano (proven@mit.edu)
360 * Removed narrow.h and widen.h
362 Wed Jan 25 17:07:17 1995 Chris Provenzano (proven@mit.edu)
364 * Removed all narrow types and references to wide.h and narrow.h
365 * base-defs.h Typedef krb5_boolean, krb5_msgtype, krb5_kvno,
366 krb5_addrtype, krb5_keytyp, krb5_enctype, krb5_cksumtype,
367 and krb5_authdatatype as int.
368 * kdb.h Made keytype in krb5_encrypted_keyblock explicitly short
369 for backwards compatibility.
371 Sun Jan 22 18:17:06 1995 John Gilmore (gnu@cygnus.com)
373 * preauth.h, rsa-md5.h: Protect against multiple inclusion.
375 Fri Jan 13 15:23:47 1995 Chris Provenzano (proven@mit.edu)
377 * Added krb5_context to all krb5_routines
379 * Removed DECLARG and OLDDECLARG from base-defs.h (and any file that
380 was using it.) The next thing to do is make all narrow types
381 wide types and remove narrow.h and wide.h.
383 Thu Jan 12 01:55:54 1995 Mark Eichin <eichin@cygnus.com>
385 * Makefile.in (install): constructed headers come from the build
386 tree, not the source tree.
388 Fri Dec 23 22:29:43 1994 Theodore Y. Ts'o (tytso@dcl)
390 * krb5.h (krb5_cred): Add enc_part2 member which may point to the
391 unecrypted version, if it's available.
393 Mon Dec 19 21:53:33 1994 Theodore Y. Ts'o (tytso@dcl)
395 * krb5.h (krb5_context): Add new typdef for krb5_context.
397 * libos.h (krb5_os_context): Add new typedef for krb5_os_context.
399 * func-proto.h (krb5_init_context, krb5_free_context): Add new
402 * los-proto.h (krb5_init_os_context, krb5_free_os_context): Add new
405 Wed Nov 30 16:16:54 1994 Theodore Y. Ts'o (tytso@dcl)
407 * configure.in: Add support for --enable-athena and --with-krb4
408 (to set KRB5_KRB4_COMPAT).
410 * Makefile.in: Remove remnants of unifdef support for building
411 osconf.h and config.h, left over from the imake build system.
413 Mon Nov 21 14:43:14 1994 Theodore Y. Ts'o (tytso@dcl)
415 * func-proto.h (krb5_encode_kdc_rep, krb5_encrypt_tkt_part):
416 Change to use new function prototypes.
418 * encryption.h (krb5_eblock_keytype, krb5_eblock_enctype): Define
419 new macros for finding the key type and encryption type of
422 Fri Nov 18 17:53:38 1994 Theodore Y. Ts'o (tytso@dcl)
424 * kdb.h (KRB5_KDB_SUPPORT_DESMD5): Add new attribute which defines
425 whether or not a server supports DES/MD5.
427 Fri Nov 18 01:28:47 1994 Mark Eichin <eichin@cygnus.com>
429 * Makefile.in (install): elide dependency so $(srcdir) works; use
431 (ET_HEADERS): new variable for the names of the headers that
432 lib/krb5/error_tables builds and installs here (so that they get
433 pushed out to the installed include directory.)
434 (BUILT_HEADERS): locally built headers, for all, install, and
436 (clean): delete built and et headers.
438 Fri Nov 18 01:15:00 1994 Mark Eichin <eichin@cygnus.com>
440 * configure.in: use KRB5_POSIX_LOCKS, AC_EGREP_HEADER. (from
443 Thu Nov 10 22:04:19 1994 Theodore Y. Ts'o (tytso@dcl)
445 * hostaddr.h (krb5_address): Add magic number field.
447 Tue Nov 8 17:55:47 1994 Theodore Y. Ts'o (tytso@dcl)
449 * encryption.h (krb5_string_to_key, krb5_random_key): Change
450 internal calling signature to pass in the encryption
451 block, so that the encryption type in the keyblock
452 structure can be properly initialized.
454 Thu Nov 3 16:38:44 1994 Theodore Y. Ts'o (tytso@dcl)
456 * encryption.h (krb5_keyblock): Added a field to hold an
457 encryption type in the keyblock field --- so routines have
458 a hint of which encryption type they should use.
460 * error_def.h: Add support for the kv5m error table. (For magic
463 Mon Oct 31 14:43:07 1994 Theodore Y. Ts'o (tytso@dcl)
465 * configure.in: Move WITH_CCOPTS and WITH_KRB5ROOT to the
466 beginning of the file. Otherwise the other tests won't
467 get the CCOPTS flags correct while doing the feature
470 Tue Oct 25 23:54:25 1994 Theodore Y. Ts'o (tytso@dcl)
472 * ext-proto.h (strdup): If the header files have strdup, don't try
475 Fri Oct 14 00:40:01 1994 Theodore Y. Ts'o (tytso@dcl)
477 * mit-des.h: Add declaration for krb5_des_md5_cst_entry.
479 * mit-des.h: Change name of the des_crc cryptosystem from
480 krb5_des_cst_entry to krb5_des_crc_cst_entry.
482 Tue Oct 4 14:51:32 1994 Theodore Y. Ts'o (tytso@dcl)
484 * encryption.h: Cast various potential shorts to ints. This is
485 not quite right either, but the whole encryption interface
488 * keytab.h (krb5_kt_ops.resolv): Resolve's first argument is a const.
490 * encryption.h: Add magic number to encryption structures.
492 Mon Oct 3 18:45:55 1994 Theodore Y. Ts'o (tytso@dcl)
494 * kdb.h: Add magic number to _krb5_db_entry. (This among other
495 things will cause a backwards incompatible change to the database
496 format.) The previous magic number changes also force a database
497 format change; we will eventually need to completely redo how we
498 encode the database format, so that it isn't structure layout
501 * Makefile.in: Fix install to obey ${DESTDIR}, copy conf.h and
502 osconf.h from build tree.
