1OpenPAM Micrampelis                                             2012-05-26
2
3 - FEATURE: Add an openpam_readword(3) function which reads the next
4   word from an input stream, applying shell quoting and escaping
5   rules.  Add numerous unit tests for openpam_readword(3).
6
7 - FEATURE: Add an openpam_readlinev(3) function which uses the
8   openpam_readword(3) function to read words from an input stream one
9   at a time until it reaches an unquoted, unescaped newline, and
10   returns an array of those words.  Add several unit tests for
11   openpam_readlinev(3).
12
13 - FEATURE: Add a PAM_HOST item which pam_start(3) initializes to the
14   machine's hostname.  This was implemented in Lycopsida but
15   inadvertantly left out of the release notes.
16
17 - FEATURE: In pam_get_authtok(3), if neither the application nor the
18   module have specified a prompt and PAM_HOST and PAM_RHOST are both
19   defined but not equal, use a different default prompt that includes
20   PAM_USER and PAM_HOST.
21
22 - ENHANCE: Rewrite the policy parser to used openpam_readlinev(),
23   which greatly simplifies the code.
24
25 - ENHANCE: The previous implementation of the policy parser relied on
26   the openpam_readline(3) function, which (by design) munges
27   whitespace and understands neither quotes nor backslash escapes.
28   As a result of the aforementioned rewrite, whitespace, quotes and
29   backslash escapes in policy files are now handled in a consistent
30   and predictable manner.
31
32 - ENHANCE: On platforms that have it, use fdlopen(3) to load modules.
33   This closes the race between the ownership / permission check and
34   the dlopen(3) call.
35
36 - ENHANCE: Reduce the amount of pointless error messages generated
37   while searching for a module.
38
39 - ENHANCE: Numerous documentation improvements, both in content and
40   formatting.
41
42 - BUGFIX: A patch incorporated in Lycopsida inadvertantly changed
43   OpenPAM's behavior when several policies exist for the same
44   service, from ignoring all but the first to concatenating them all.
45   Revert to the original behavior.
46
47 - BUGFIX: Plug a memory leak in the policy parser.
48============================================================================
49OpenPAM Lycopsida                                               2011-12-18
50
51 - ENHANCE: removed static build autodetection, which didn't work
52   anyway.  Use an explicit, user-specified preprocessor variable
53   instead.
54
55 - ENHANCE: cleaned up the documentation a bit.
56
57 - ENHANCE: added openpam_subst(3), allowing certain PAM items to be
58   embedded in strings such as prompts.  Apply it to the prompts used
59   by pam_get_user(3) and pam_get_authtok(3).
60
61 - ENHANCE: added support for the user_prompt, authtok_prompt and
62   oldauthtok_prompt module options, which override the prompts passed
63   by the module to pam_set_user(3) and pam_get_authtok(3).
64
65 - ENHANCE: rewrote the policy parser to support quoted option values.
66
67 - ENHANCE: added pamtest(1), a tool for testing modules and policies.
68
69 - ENHANCE: added code to check the ownership and permissions of a
70   module before loading it.
71
72 - ENHANCE: added / improved input validation in many cases, including
73   the policy file and some function arguments.
74============================================================================
75OpenPAM Hydrangea                                               2007-12-21
76
77 - ENHANCE: when compiling with GCC, mark up API functions with GCC
78   attributes where appropriate.
79
80 - BUGFIX: fixed numerous warnings uncovered by GCC 4.
81
82 - ENHANCE: building the documentation is now optional.
83
84 - ENHANCE: corrected a number of mistakes and style issues in the
85   build system.
86
87 - ENHANCE: API function arguments are now const where appropriate, to
88   match corresponding changes in the Solaris PAM and Linux-PAM APIs.
89
90 - ENHANCE: corrected a number of C namespace violations.
91
92 - ENHANCE: the module cache has been removed, allowing long-lived
93   applications to pick up module changes.  This also allows multiple
94   threads to use PAM simultaneously (as long as they use separate PAM
95   contexts), since the module cache was the only part of OpenPAM that
96   was not thread-safe.

107   module directory so we never call dlopen(3) with a relative path.
108
109 - ENHANCE: add a pam.conf(5) manual page.
110============================================================================
111OpenPAM Feterita                                                2005-02-01

150
151 - BUGFIX: Staticize some variables which shouldn't be global.

314 - ENHANCE: Add openpam_{borrow,restore}_cred(), for temporarily
315   switching to user credentials.
316
317 - ENHANCE: Add openpam_free_data(), a generic cleanup function for

319============================================================================
320OpenPAM Centaury                                                2002-03-14
321
322 - BUGFIX: Add missing #include <string.h> to openpam_log.c.
323
324 - BUGFIX: s/PAM_REINITIALISE_CRED/PAM_REINITIALIZE_CRED/.  XSSO uses
325   the former, but Solaris and Linux-PAM use the latter.
326
327 - BUGFIX: The dynamic loader and the module cache contained a number
328   of bugs which would cause a segmentation fault if pam_start(3) was
329   called again after pam_end(3), as happens in login(1), xdm(1) etc.
330   after a failed login.
331
332 - BUGFIX: Refer to a module by the name used in the policy file, even
333   if the module that was actually loaded was versioned.
334
335 - ENHANCE: Suppress debugging logs, unless compiled with -DDEBUG.
336============================================================================
337OpenPAM Celandine                                               2002-03-05
338
339 - BUGFIX: PAM_TRY_AGAIN is a valid return value for pam_chauthtok().
340
341 - BUGFIX: Run passwd chain twice, first with the PAM_PRELIM_CHECK
342   flag set, then with the PAM_UPDATE_AUTHTOK flag set.
343
344 - BUGFIX: Failure of a "sufficient" module should not terminate the
345   passwd chain if the PAM_PRELIM_CHECK flag is set.
346
347 - BUGFIX: Clear PAM_AUTHTOK after running the service modules.
348
349 - ENHANCE: Prevent applications from specifying the PAM_PRELIM_CHECK
350   or PAM_UPDATE_AUTHTOK flags themselves.
351
352 - BUGFIX: openpam_set_option() did not support changing the value of
353   an existing option.
354
355 - ENHANCE: Add support for module versioning.  OpenPAM will prefer a
356   module with the same version number as the library itself to one
357   with no version number at all.
358============================================================================
359OpenPAM Cantaloupe                                              2002-02-22
360
361 - BUGFIX: The proper use of PAM_SYMBOL_ERR is to indicate an invalid
362   argument to pam_[gs]et_item(3), not to indicate dlsym(3) failures.
363
364 - ENHANCE: Add in-line documentation in most source files, and a Perl
365   script that generates mdoc code from that.
366
367 - BUGFIX: The environment list was not properly NULL-terminated.
368
369 - ENHANCE: Allow the PAM_AUTHTOK_PROMPT item to override the prompt
370   specified by the module.
371
372 - BUGFIX: PAM_NUM_ITEMS was set too low.  It has been moved to
373   pam_constants.h to avoid it going stale again.
374
375 - ENHANCE: Move all code related to static modules into a separate
376   file.
377
378 - ENHANCE: openpam_ttyconv() now masks most signals while prompting the
379   user, and supports setting a timeout (which defaults to off).
380
381 - BUGFIX: Some manual pages referenced XSSO even though they
382   documented OpenPAM-specific functions.
383
384 - ENHANCE: Added openpam_get_option() and openpam_set_option().
385
386 - ENHANCE: openpam_get_authtok() now respects the echo_pass,
387   try_first_pass, and use_first_pass options.
388============================================================================
389OpenPAM Caliopsis                                               2002-02-13
390
391Fixed a number of bugs in the previous release, including:
392  - a number of bugs in and related to pam_[gs]et_item(3)
393  - off-by-one bug in pam_start.c would trim last character off certain
394    configuration lines
395  - incorrect ordering of an array in openpam_load.c would cause service
396    module functions to get mixed up
397  - missing 'continue' in openpam_dispatch.c caused successes to be
398    counted as failures
399============================================================================
400OpenPAM Calamite                                                2002-02-09
