4
5- Fixes to AUT_SOCKUNIX token parsing.
6- IPv6 support for au_to_me(3).
7- Improved robustness in the parsing of audit_control, especially long
8 flags/naflags strings and whitespace in all fields.
9- Add missing conversion of a number of FreeBSD/Mac OS X errnos to/from BSM
10 error number space.
11
12OpenBSM 1.1
13
14- Change auditon(2) parameters and data structures to be 32/64-bit architecture
15 independent. Add more information to man page about auditon(2) parameters.
16- Add wrapper functions for auditon(2) to use legacy commands when the new
17 commands are not supported.
18- Add default for 'expire-after' in audit_control to expire trail files when
19 the audit directory is more than 10 megabytes ('10M').
20- Interface to convert between local and BSM fcntl(2) command values has been
21 added: au_bsm_to_fcntl_cmd(3) and au_fcntl_cmd_to_bsm(3), along with
22 definitions of constants in audit_fcntl.h.
23- A bug, introduced in OpenBSM 1.1 alpha 4, in which AUT_RETURN32 tokens
24 generated by audit_submit(3) were improperly encoded has been fixed.
25- Fix example in audit_submit(3) man page. Also, make it clear that we want
26 the audit ID as the argument.
27- A new audit event class 'aa', for post-login authentication and
28 authorization events, has been added.
29
30OpenBSM 1.1 beta 1
31
32- The filesz parameter in audit_control(5) now accepts suffixes: 'B' for
33 Bytes, 'K' for Kilobytes, 'M' for Megabytes, and 'G' for Gigabytes.
34 For legacy support no suffix defaults to bytes.
35- Audit trail log expiration support added. It is configured in
36 audit_control(5) with the expire-after parameter. If there is no
37 expire-after parameter in audit_control(5), the default, then the audit
38 trail files are not expired and removed. See audit_control(5) for
39 more information.
40- Change defaults in audit_control: warn at 5% rather than 20% free for audit
41 partitions, rotate automatically at 2mb, and set the default policy to
42 cnt,argv rather than cnt so that execve(2) arguments are captured if
43 AUE_EXECVE events are audited. These may provide more usable defaults for
44 many users.
45- Use au_domain_to_bsm(3) and au_socket_type_to_bsm(3) to convert
46 au_to_socket_ex(3) arguments to BSM format.
47- Fix error encoding AUT_IPC_PERM tokens.
48
49OpenBSM 1.1 alpha 5
50
51- Stub libauditd(3) man page added.
52- All BSM error number constants with BSM_ERRNO_.
53- Interfaces to convert between local and BSM socket types and protocol
54 families have been added: au_bsm_to_domain(3), au_bsm_to_socket_type(3),
55 au_domain_to_bsm(3), and au_socket_type_to_bsm(3), along with definitions
56 of constants in audit_domain.h and audit_socket_type.h. This improves
57 interoperability by converting local constant spaces, which vary by OS, to
58 and from Solaris constants (where available) or OpenBSM constants for
59 protocol domains not present in Solaris (a fair number). These routines
60 should be used when generating and interpreting extended socket tokens.
61- Fix build warnings with full gcc warnings enabled on most supported
62 platforms.
63- Don't compile error strings into bsm_errno.c when building it in the kernel
64 environment.
65- When started by launchd, use the label com.apple.auditd rather than
66 org.trustedbsd.auditd.
67
68OpenBSM 1.1 alpha 4
69
70- With the addition of BSM error number mapping, we also need to map the
71 local error number passed to audit_submit(3) to a BSM error number, rather
72 than have the caller perform that conversion.
73- Reallocate user audit events to avoid collisions with Solaris; adopt a more
74 formal allocation scheme, and add some events allocated in Solaris that
75 will be of immediate use on other platforms.
76- Add an event for Calife.
77- Add au_strerror(3), which allows generating strings for BSM errors
78 directly, rather than requiring applications to map to the local error
79 space, which might not be able to entirely represent the BSM error number
80 space.
81- Major auditd rewrite for launchd(8) support. Add libauditd library that is
82 shared between launchd and auditd.
83- Add AUDIT_TRIGGER_INITIALIZE trigger (sent via 'audit -i') for (re)starting
84 auditing under launchd(8) on Mac OS X.
85- Add 'current' symlink to active audit trail.
86- Add crash recovery of previous audit trail file when detected on audit
87 startup that it has not been properly terminated.
88- Add the event AUE_audit_recovery to indicated when an audit trail file has
89 been recovered from not being properly terminated. This event is stored
90 in the new audit trail file and includes the path of recovered audit trail
91 file.
92- Mac OS X and FreeBSD dependent code in auditd.c is separated into
93 auditd_darwin.c and auditd_fbsd.c files.
94- Add an event for the posix_spawn(2) and fsgetpath(2) Mac OS X system calls.
95- For Mac OS X, we use ASL(3) instead of syslog(3) for logging.
96- Add support for NOTICE level logging.
97
98OpenBSM 1.1 alpha 3
99
100- Add two new functions, au_bsm_to_errno() and au_errno_to_bsm(), to map
101 between BSM error numbers (largely the Solaris definitions) and local
102 errno(2) values for 32-bit and 64-bit return tokens. This is required as
103 operating systems don't agree on some of the values of more recent error
104 numbers.
105- Fix a bug how au_to_exec_args(3) and au_to_exec_env(3) calculates the total
106 size for the token. This bug resulted in "unknown" tokens being printed
107 after the exec args/env tokens.
108- Support for AUT_SOCKET_EX extended socket tokens, which describe a socket
109 using a pair of IPv4/IPv6 and port tuples.
110- OpenBSM BSM file header version bumped for 1.1 release.
111- Deprecated Darwin constants, such as TRAILER_PAD_MAGIC, removed.
112
113OpenBSM 1.1 alpha 2
114
115- Include files in OpenBSM are now broken out into two parts: library builds
116 required solely for user space, and system includes, which may also be
117 required for use in the kernels of systems integrating OpenBSM. Submitted
118 by Stacey Son.
119- Configure option --with-native-includes allows forcing the use of native
120 include for system includes, rather than the versions bundled with OpenBSM.
121 This is intended specifically for platforms that ship OpenBSM, have adapted
122 versions of the system includes in a kernel source tree, and will use the
123 OpenBSM build infrastructure with an unmodified OpenBSM distribution,
124 allowing the customized system includes to be used with the OpenBSM build.
125 Submitted by Stacey Son.
126- Various strcpy()'s/strcat()'s have been changed to strlcpy()'s/strlcat()'s
127 or asprintf(). Added compat/strlcpy.h for Linux.
128- Remove compatibility defines for old Darwin token constant names; now only
129 BSM token names are provided and used.
130- Add support for extended header tokens, which contain space for information
131 on the host generating the record.
132- Add support for setting extended host information in the kernel, which is
133 used for setting host information in extended header tokens. The
134 audit_control file now supports a "host" parameter which can be used by
135 auditd to set the information; if not present, the kernel parameters won't
136 be set and auditd uses unextended headers for records that it generates.
137
138OpenBSM 1.1 alpha 1
139
140- Add option to auditreduce(1) which allows users to invert sense of
141 matching, such that BSM records that do not match, are selected.
142- Fix bug in audit_write() where we commit an incomplete record in the
143 event there is an error writing the subject token. This was submitted
144 by Diego Giagio.
145- Build support for Mac OS X 10.5.1 submitted by Eric Hall.
146- Fix a bug which resulted in host XML attributes not being printed
147 while processing extended header tokens. This patch was submitted by
148 Martin Voros.
149- Constification of function arguments so that const strings can be passed
150 as arguments to tokens. This patch was submitted by Xin LI.
151- Modify the -m option so users can select more then one audit event.
152- For Mac OS X, added Mach IPC support for audit trigger messages.
153- Fixed a bug in getacna() which resulted in a locking problem on Mac OS X.
154- Added LOG_PERROR flag to openlog when -d option is used with auditd.
155- AUE events added for Mac OS X Leopard system calls.
156
157OpenBSM 1.0
158
159- Fix bug in auditreduce(1) which resulted in a memory fault/crash when
160 the user specified an event name with -m.
161- Remove AU_.* hard-coded audit class constants, as audit classes are now
162 entirely dynamically configured using /etc/security/audit_class.
163
164OpenBSM 1.0 alpha 15
165
166- Fix bug when processing in_addr_ex tokens.
167- Restore the behavior of printing the string/text specified while
168 auditing arg32 tokens.
169- Synchronized audit event list to Solaris, picking up the *at(2) system call
170 definitions, now required for FreeBSD and Linux. Added additional events
171 for *at(2) system calls not present in Solaris.
172- Bugs in auditreduce(1) fixed allowing partial date strings to be used in
173 filtering events.
174
175OpenBSM 1.0 alpha 14
176
177- Fix endian issues when processing IPv6 addresses for extended subject
178 and process tokens.
179- gcc41 warnings clean.
180- Teach audit_submit(3) about getaudit_addr(2).
181- Add support for zonename tokens.
182
183OpenBSM 1.0 alpha 13
184
185- compat/clock_gettime.h now provides a compatibility implementation of
186 clock_gettime(), which fixes building on Mac OS X.
187- Countless man page improvements, markup fixes, content fixs, etc.
188- XML printing support via "praudit -x".
189- audit.log.5 expanded to include additional BSM token types.
190- Added encoding and decoding routines for process64_ex, process32_ex,
191 subject32_ex, header64, and attr64 tokens.
192- Additional audit event identifiers for listen, mlockall/munlockall,
193 getpath, POSIX message queues, and mandatory access control.
194
195OpenBSM 1.0 alpha 12
196
197- Correct bug in auditreduce which prevented the -c option from working
198 correctly when the user specifies to process successful or failed events.
199 The problem stemmed from not having access to the return token at the time
200 the initial preselection occurred, but now a second preselection process
201 occurs while processing the return token.
202- getacfilesz(3) API added to read new audit_control(5) filesz setting,
203 which auditd(8) now sets the kernel audit trail rotation size to.
204- auditreduce(1) now uses stdin if no file names are specified on the command
205 line; this was the documented behavior previously, but it was not
206 implemented. Be more specific in auditreduce(1)'s examples section about
207 what might be done with the output of auditreduce.
208- Add audit_warn(5) closefile event so that administrators can hook
209 termination of an audit trail file. For example, this might be used to
210 compress the trail file after it is closed.
211- auditreduce(1) now uses regular expressions for pathname matching. Users can
212 now supply one or more (comma delimited) regular expressions for searching
213 the pathnames. If one of the regular expressions is prefixed with a tilde
214 (~), and a path matches, it will be excluded from the search results.
215
216OpenBSM 1.0 alpha 11
217
218- Reclassify certain read/write operations as having no class rather than the
219 fr/fw class; our default classes audit intent (open) not operations (read,
220 write).
221- Introduce AUE_SYSCTL_WRITE event so that BSD/Darwin systems can audit reads
222 and writes of sysctls as separate events. Add additional kernel
223 environment and jail events for FreeBSD.
224- Break AUDIT_TRIGGER_OPEN_NEW into two events, AUDIT_TRIGGER_ROTATE_USER
225 (issued by the user audit(8) tool) and AUDIT_TRIGGER_ROTATE_KERNEL (issued
226 by the kernel audit implementation) so that they can be distinguished.
227- Disable rate limiting of rotate requests; as the kernel doesn't retransmit
228 a dropped request, the log file will otherwise grow indefinitely if the
229 trigger is dropped.
230- Improve auditd debugging output.
231- Fix a number of threading related bugs in audit_control file reading
232 routines.
233- Add APIs au_poltostr() and au_strtopol() to convert between text
234 representations of audit_control policy flags and the flags passed to
235 auditon(A_SETPOLICY) and retrieved from auditon(A_GETPOLICY).
236- Add API getacpol() to return the 'policy:' entry from audit_control, an
237 extension to the Solaris file format to allow specification of policy
238 persistent flags.
239- Update audump to print the audit_control policy field.
240- Update auditd to read the audit_control policy field and set the kernel
241 policy to match it when configuring/reconfiguring. Remove the -s and -h
242 arguments as these policies are now set via the configuration file. If a
243 policy line is not found in the configuration file, continue with the
244 current default of setting AUDIT_CNT.
245- Fix bugs in the parsing of large execve(2) arguments and environmental
246 variable tokens; increase maximum parsed argument and variable count.
247- configure now detects strlcat(), used by policy-related functions.
248- Reference token and record sample files added to test tree.
249
250OpenBSM 1.0 alpha 10
251
252- auditd now generates complete audit records for its events, as required for
253 application-submitted audit records in the FreeBSD kernel audit
254 implementation.
255
256OpenBSM 1.0 alpha 9
257
258- Rename many OpenBSM-specific constants and API elements containing the
259 strings "BSM" and "bsm" to "AUDIT" and "audit", observing that this is true
260 for almost all existing constants and APIs.
261- Instead of passing a per-instance cookie directly into all audit filter
262 APIs, pass in the audit filter daemon state pointer, which is then used by
263 the module using an audit_filter_{get,set}cookie() API. This will allow
264 future service APIs provided by the filter daemon to maintain their own
265 state -- for example, per-module preselection state.
266
267OpenBSM 1.0 alpha 8
268
269- Correct typo in definition of AUR_INT.
270- Adopt OpenSolaris constant values for AUDIT_* configuration flags.
271- Arguments to au_to_exec_args() and au_to_exec_env() no longer const.
272- Add kernel versions of au_to_exec_args() and au_to_exec_env().
273- Fix exec argument type that is printed for env strings from 'arg' to 'env'.
274- New OpenBSM token version number assigned, constants added for other
275 commonly seen version numbers.
276- OpenBSM-specific events assigned numbers in the 43xxx range to avoid future
277 collisions with Solaris. Darwin events renamed to AUE_DARWIN_foo, as they
278 are now deprecated numberings.
279- autoconf now detects clock_gettime(), which is not available on Darwin.
280- praudit output fixes relating to arg32 and arg64 tokens.
281- Maximum record size updated to 64k-1 to match Solaris record size limit.
282- Various style and comment cleanups in include files.
283
284OpenBSM 1.0 alpha 7
285
286- Adopted Solaris-compatible format for subject32_ex and subject64_ex
287 tokens, which previously did not correctly implement variable length
288 address storage.
289- Prefer inttypes.h to stdint.h; enhance queue.h detection to test for
290 TAILQ_FOREACH_SAFE(), which is present in recent BSD queue.h's, but not
291 older ones. OpenBSM now builds on some FreeBSD 4.x versions.
292- New event types for extended attributes, ACLs, and scheduling.
293
294OpenBSM 1.0 alpha 6
295
296- Use AU_TO_WRITE and AU_NO_TO_WRITE for the 'keep' argument to au_close();
297 previously we used hard-coded 0 and 1 values.
298- Add man page for au_open(), au_write(), au_close(), and
299 au_close_buffer().
300- Support a more complete range of data types for the arbitrary data token:
301 add AUR_CHAR (alias to AUR_BYTE), remove AUR_LONG, add AUR_INT32 (alias
302 to AUR_INT), add AUR_INT64.
303- Add au_close_token(), which allows writing a single token_t to a memory
304 buffer. Not likely to be used much by applications, but useful for
305 writing test tools.
306- Modify au_to_file() so that it accepts a timeval in user space, not just
307 kernel -- this is not a Solaris BSM API so can be modified without
308 causing compatibility issues.
309- Define a new API, au_to_header32_tm(), which adds a struct timeval
310 argument to the ordinary au_to_header32(), which is now implemented by
311 wrapping au_to_header32_tm() and calling gettimeofday(). #ifndef KERNEL
312 the APIs that invoke gettimeofday(), rather than having a variable
313 definition. Don't try to retrieve time zone information using
314 gettimeofday(), as it's not needed, and introduces possible failure
315 modes.
316- Don't perform byte order transformations on the addr/machine fields of
317 the terminal ID that appears in the process32/subject32 tokens. These
318 are assumed to be IP addresses, and as such, to be in network byte
319 order.
320- Universally, APIs now assume that IP addresses and ports are provided
321 in network byte order. APIs now generally provide these types in
322 network byte order when decoding.
323- Beginnings of an OpenBSM test framework can now be found in openbsm/test.
324 This code is not built or installed by default.
325- auditd now assigns more appropriate syslog levels to its debugging and
326 error information.
327- Support for audit filters introduced: audit filters are dynamically
328 loaded shared objects that run in the context of a new daemon,
329 auditfilterd. The daemon reads from an audit pipe and feeds both BSM and
330 parsed versions of records to shared objects using a module API. This
331 will provide a framework for the writing of intrusion detection services.
332- New utility API, audit_submit(), added to capture common elements of audit
333 record submission for many applications.
334
335OpenBSM 1.0 alpha 5
336
337- Update install notes to indicate /etc files are to be installed manually.
338- On systems without LOG_SECURITY, use LOG_AUTH.
339- Convert to autoconf/automake in order to move to a more portable (not
340 BSD-specific) build infrastructure, and more easy conditional building of
341 components. Currently, the primary feature loss is that automake does
342 not have native support for manual symlinks. This will be addressed in a
343 future OpenBSM release.
344- Add compat/queue.h, to be used on systems dated BSD queue macro libraries
345 (as found on Linux).
346- Rename CHANGELOG to HISTORY, as our change log doesn't follow some of the
347 existing conventions for a CHANGELOG.
348- Some private data structures moved from audit.h to audit_internal.h to
349 prevent inappropriate use by applications and name space pollution.
350- Improved detection and use of endian macros using autoconf.
351- Avoid non-portable use of struct in6_addr, which is largely opaque.
352- Avoid leaking BSD kernel socket related token code to user space in
353 bsm_token.c.
354- Teach System V IPC calls to look for Linux naming variations for certain
355 struct ipc_perm fields.
356- Test for audit system calls, and if not present, don't build
357 bsm_wrappers.c, bsm_notify.c, audit(8), and auditd(8), which rely on
358 those system calls.
359- au_close() is not implemented on systems that don't have audit system
360 calls, but au_close_buffer() is.
361- Work around missing BSDisms in bsm_wrapper.c.
362- Fix nested includes so including libbsm.h in an application on Linux
363 picks up the necessary definitions.
364
365OpenBSM 1.0 alpha 4
366
367- Remove "audit" user example from audit_user, as it's not present on most
368 systems.
369- Add cannot_audit() function non-Darwin systems that wraps auditon();
370 required by OpenSSH BSM support. Convert Darwin cannot_audit() into a
371 function rather than a macro.
372- Library build fixed on Darwin following include file tweaks. The native
373 Darwin sys/audit.h conflicts with bsm/audit.h due to duplicate types, so
374 for now we force bsm_wrappers.c to not perform a nested include of
375 sys/audit.h.
376
377OpenBSM 1.0 alpha 3
378
379- Man page formatting, cross reference, mlinks, and accuracy improvements.
380- auditd and tools now compile and run on FreeBSD/arm.
381- auditd will now fchown() the trail file to the audit review group, if
382 defined at compile-time.
383- Added AUE_SYSARCH for FreeBSD.
384- Definition of AUE_SETFSGID fixed for Linux.
385
386OpenBSM 1.0 alpha 2
387
388- Man page formatting improvements.
389- A number of new audit event identifiers for FreeBSD, Linux, and POSIX.1b
390 events.
391- Remove 'tfm' class, unused in OpenBSM.
392
393OpenBSM 1.0 alpha 1
394
395- Import of Darwin74 BSM drop
396- Use 'syslog' for audit log warnings, rather than echoing to a file in
397 audit_warn.
398- Compile using BSD make infrastructure.
399- Integrate bsm/ include files from Darwin74 XNU drop into OpenBSM.
400- Narrow set of symbols and defines that are exposed in user space: don't
401 compile in code relying on kernel-only types such as 'struct socket'.
402- Add README, including basic build documentation.
403- Compilation of Apple-specific notify and Machroutines now #ifdef __APPLE__.
404- Staticize libbsm global variables to avoid leakage into applications.
405- Add free_au_user_ent() so that au_user_ent's don't have to be leaked.
406- Clean up bogus nul-termination checks in libbsm.
407- Add libbsm API man pages: au_class.3 au_control.3 au_event.3
408 au_free_token.3 au_io.3 au_mask.3 au_token.3 au_user.3 libbsm.3.
409- Add man pages for BSM system calls: audit.2 auditctl.2 auditon.2 getaudit.2
410 getauid.2 setaudit.2 setauid.2
411- Modify various libbsm interfaces to more consistently return 'errno' values
412 on failure.
413- Break out au_close() into constituent parts, allowing records to be written
414 to memory as well as files.
415- Prefix various defines with 'BSM_' to reduce name space pollution.
416- Added audit_internal.h, which can be used by a kernel audit implementation
417 wanting to rely on libbsm components.
418- Build with warnings, and eliminate warnings.
419- Make libbsm endian-independent, storing and reading BSM are big endian
420 (network byte order) rather than native byte order. More consistently
421 print IP addresses using the IP address print routine. These changes
422 make use of sys/endian.h from *BSD; since this isn't present on Darwin,
423 add it to OpenBSM as compat/endian.h, which is used only on Darwin.
424- Import of Darwin80 BSM drop, including 64-bit file IDs, better
425 documentation of private APIs, and bug fixes.
426- White space cleanup.
427- Add audit.log.5, a first cut at a man page documenting the BSM file format.
428- Teach au_read_rec() to recognize stand-alone file tokens, which are present
429 at the beginning and end of Solaris audit trails. Technically, these
430 appear to violate the high level BSM spec, which suggests that all tokens
431 are present in records, but need to be supported.
432- Implement HEADER64, ATTR64, SUBJECT64 token types, which make it possible
433 to run praudit(1) on basic Solaris BSM streams.
434- Switched to Solaris spelling of token names; Darwin spellings are now
435 deprecated and will be removed in a future version of OpenBSM.
436- Adopt Solaris model for representing IPv4 and IPv6 addresses.
437- Prefer C99 types.
438- Attempt to universally adopt the BSD style(9) coding style for
439 consistency.
440- auditreduce(1) now has a usage message.
441- Update support for auditctl(2) system call to support FreeBSD.
442- Add support for /dev/audit as the trigger source on FreeBSD.
443- Add additional event types for Darwin, FreeBSD, and Solaris. Annotate
444 conflicts (there are a few, unfortunately). Correct spellings, comment,
445 sort, etc. These include {get,set}res[ug]id(), sendfile(), lchflags(),
446 eaccess(), kqueue(), kevent(), poll(), lchmod().
447- Relicensed under a BSD license, many thanks to Apple, Inc!
448- Many bug fixes, cleanups, thread safety in the class, control, event,
449 and user system audit databases. Annotate some persisting atomicity
450 bugs associated with the API and implementation.
451- Add audump test tool.
452- Adopt OpenSolaris BSM API memory semantics: caller allocates memory,
453 or static memory is returned for non-_r() versions of API calls.
454 _free() calls dropped as a result, and source code compatibility with
455 OpenSolaris improved significantly.
456- Annotate BSM events with origin OS and compatibility information.
457- auditd(8), audit(8) added to the OpenBSM distribution. auditd extended
458 to support reloading of kernel event table.
459- Allow comments in /etc/security configuration files.

11- Fixes to AUT_SOCKUNIX token parsing.
12- IPv6 support for au_to_me(3).
13- Improved robustness in the parsing of audit_control, especially long
14 flags/naflags strings and whitespace in all fields.
15- Add missing conversion of a number of FreeBSD/Mac OS X errnos to/from BSM
16 error number space.
17
18OpenBSM 1.1
19
20- Change auditon(2) parameters and data structures to be 32/64-bit architecture
21 independent. Add more information to man page about auditon(2) parameters.
22- Add wrapper functions for auditon(2) to use legacy commands when the new
23 commands are not supported.
24- Add default for 'expire-after' in audit_control to expire trail files when
25 the audit directory is more than 10 megabytes ('10M').
26- Interface to convert between local and BSM fcntl(2) command values has been
27 added: au_bsm_to_fcntl_cmd(3) and au_fcntl_cmd_to_bsm(3), along with
28 definitions of constants in audit_fcntl.h.
29- A bug, introduced in OpenBSM 1.1 alpha 4, in which AUT_RETURN32 tokens
30 generated by audit_submit(3) were improperly encoded has been fixed.
31- Fix example in audit_submit(3) man page. Also, make it clear that we want
32 the audit ID as the argument.
33- A new audit event class 'aa', for post-login authentication and
34 authorization events, has been added.
35
36OpenBSM 1.1 beta 1
37
38- The filesz parameter in audit_control(5) now accepts suffixes: 'B' for
39 Bytes, 'K' for Kilobytes, 'M' for Megabytes, and 'G' for Gigabytes.
40 For legacy support no suffix defaults to bytes.
41- Audit trail log expiration support added. It is configured in
42 audit_control(5) with the expire-after parameter. If there is no
43 expire-after parameter in audit_control(5), the default, then the audit
44 trail files are not expired and removed. See audit_control(5) for
45 more information.
46- Change defaults in audit_control: warn at 5% rather than 20% free for audit
47 partitions, rotate automatically at 2mb, and set the default policy to
48 cnt,argv rather than cnt so that execve(2) arguments are captured if
49 AUE_EXECVE events are audited. These may provide more usable defaults for
50 many users.
51- Use au_domain_to_bsm(3) and au_socket_type_to_bsm(3) to convert
52 au_to_socket_ex(3) arguments to BSM format.
53- Fix error encoding AUT_IPC_PERM tokens.
54
55OpenBSM 1.1 alpha 5
56
57- Stub libauditd(3) man page added.
58- All BSM error number constants with BSM_ERRNO_.
59- Interfaces to convert between local and BSM socket types and protocol
60 families have been added: au_bsm_to_domain(3), au_bsm_to_socket_type(3),
61 au_domain_to_bsm(3), and au_socket_type_to_bsm(3), along with definitions
62 of constants in audit_domain.h and audit_socket_type.h. This improves
63 interoperability by converting local constant spaces, which vary by OS, to
64 and from Solaris constants (where available) or OpenBSM constants for
65 protocol domains not present in Solaris (a fair number). These routines
66 should be used when generating and interpreting extended socket tokens.
67- Fix build warnings with full gcc warnings enabled on most supported
68 platforms.
69- Don't compile error strings into bsm_errno.c when building it in the kernel
70 environment.
71- When started by launchd, use the label com.apple.auditd rather than
72 org.trustedbsd.auditd.
73
74OpenBSM 1.1 alpha 4
75
76- With the addition of BSM error number mapping, we also need to map the
77 local error number passed to audit_submit(3) to a BSM error number, rather
78 than have the caller perform that conversion.
79- Reallocate user audit events to avoid collisions with Solaris; adopt a more
80 formal allocation scheme, and add some events allocated in Solaris that
81 will be of immediate use on other platforms.
82- Add an event for Calife.
83- Add au_strerror(3), which allows generating strings for BSM errors
84 directly, rather than requiring applications to map to the local error
85 space, which might not be able to entirely represent the BSM error number
86 space.
87- Major auditd rewrite for launchd(8) support. Add libauditd library that is
88 shared between launchd and auditd.
89- Add AUDIT_TRIGGER_INITIALIZE trigger (sent via 'audit -i') for (re)starting
90 auditing under launchd(8) on Mac OS X.
91- Add 'current' symlink to active audit trail.
92- Add crash recovery of previous audit trail file when detected on audit
93 startup that it has not been properly terminated.
94- Add the event AUE_audit_recovery to indicated when an audit trail file has
95 been recovered from not being properly terminated. This event is stored
96 in the new audit trail file and includes the path of recovered audit trail
97 file.
98- Mac OS X and FreeBSD dependent code in auditd.c is separated into
99 auditd_darwin.c and auditd_fbsd.c files.
100- Add an event for the posix_spawn(2) and fsgetpath(2) Mac OS X system calls.
101- For Mac OS X, we use ASL(3) instead of syslog(3) for logging.
102- Add support for NOTICE level logging.
103
104OpenBSM 1.1 alpha 3
105
106- Add two new functions, au_bsm_to_errno() and au_errno_to_bsm(), to map
107 between BSM error numbers (largely the Solaris definitions) and local
108 errno(2) values for 32-bit and 64-bit return tokens. This is required as
109 operating systems don't agree on some of the values of more recent error
110 numbers.
111- Fix a bug how au_to_exec_args(3) and au_to_exec_env(3) calculates the total
112 size for the token. This bug resulted in "unknown" tokens being printed
113 after the exec args/env tokens.
114- Support for AUT_SOCKET_EX extended socket tokens, which describe a socket
115 using a pair of IPv4/IPv6 and port tuples.
116- OpenBSM BSM file header version bumped for 1.1 release.
117- Deprecated Darwin constants, such as TRAILER_PAD_MAGIC, removed.
118
119OpenBSM 1.1 alpha 2
120
121- Include files in OpenBSM are now broken out into two parts: library builds
122 required solely for user space, and system includes, which may also be
123 required for use in the kernels of systems integrating OpenBSM. Submitted
124 by Stacey Son.
125- Configure option --with-native-includes allows forcing the use of native
126 include for system includes, rather than the versions bundled with OpenBSM.
127 This is intended specifically for platforms that ship OpenBSM, have adapted
128 versions of the system includes in a kernel source tree, and will use the
129 OpenBSM build infrastructure with an unmodified OpenBSM distribution,
130 allowing the customized system includes to be used with the OpenBSM build.
131 Submitted by Stacey Son.
132- Various strcpy()'s/strcat()'s have been changed to strlcpy()'s/strlcat()'s
133 or asprintf(). Added compat/strlcpy.h for Linux.
134- Remove compatibility defines for old Darwin token constant names; now only
135 BSM token names are provided and used.
136- Add support for extended header tokens, which contain space for information
137 on the host generating the record.
138- Add support for setting extended host information in the kernel, which is
139 used for setting host information in extended header tokens. The
140 audit_control file now supports a "host" parameter which can be used by
141 auditd to set the information; if not present, the kernel parameters won't
142 be set and auditd uses unextended headers for records that it generates.
143
144OpenBSM 1.1 alpha 1
145
146- Add option to auditreduce(1) which allows users to invert sense of
147 matching, such that BSM records that do not match, are selected.
148- Fix bug in audit_write() where we commit an incomplete record in the
149 event there is an error writing the subject token. This was submitted
150 by Diego Giagio.
151- Build support for Mac OS X 10.5.1 submitted by Eric Hall.
152- Fix a bug which resulted in host XML attributes not being printed
153 while processing extended header tokens. This patch was submitted by
154 Martin Voros.
155- Constification of function arguments so that const strings can be passed
156 as arguments to tokens. This patch was submitted by Xin LI.
157- Modify the -m option so users can select more then one audit event.
158- For Mac OS X, added Mach IPC support for audit trigger messages.
159- Fixed a bug in getacna() which resulted in a locking problem on Mac OS X.
160- Added LOG_PERROR flag to openlog when -d option is used with auditd.
161- AUE events added for Mac OS X Leopard system calls.
162
163OpenBSM 1.0
164
165- Fix bug in auditreduce(1) which resulted in a memory fault/crash when
166 the user specified an event name with -m.
167- Remove AU_.* hard-coded audit class constants, as audit classes are now
168 entirely dynamically configured using /etc/security/audit_class.
169
170OpenBSM 1.0 alpha 15
171
172- Fix bug when processing in_addr_ex tokens.
173- Restore the behavior of printing the string/text specified while
174 auditing arg32 tokens.
175- Synchronized audit event list to Solaris, picking up the *at(2) system call
176 definitions, now required for FreeBSD and Linux. Added additional events
177 for *at(2) system calls not present in Solaris.
178- Bugs in auditreduce(1) fixed allowing partial date strings to be used in
179 filtering events.
180
181OpenBSM 1.0 alpha 14
182
183- Fix endian issues when processing IPv6 addresses for extended subject
184 and process tokens.
185- gcc41 warnings clean.
186- Teach audit_submit(3) about getaudit_addr(2).
187- Add support for zonename tokens.
188
189OpenBSM 1.0 alpha 13
190
191- compat/clock_gettime.h now provides a compatibility implementation of
192 clock_gettime(), which fixes building on Mac OS X.
193- Countless man page improvements, markup fixes, content fixs, etc.
194- XML printing support via "praudit -x".
195- audit.log.5 expanded to include additional BSM token types.
196- Added encoding and decoding routines for process64_ex, process32_ex,
197 subject32_ex, header64, and attr64 tokens.
198- Additional audit event identifiers for listen, mlockall/munlockall,
199 getpath, POSIX message queues, and mandatory access control.
200
201OpenBSM 1.0 alpha 12
202
203- Correct bug in auditreduce which prevented the -c option from working
204 correctly when the user specifies to process successful or failed events.
205 The problem stemmed from not having access to the return token at the time
206 the initial preselection occurred, but now a second preselection process
207 occurs while processing the return token.
208- getacfilesz(3) API added to read new audit_control(5) filesz setting,
209 which auditd(8) now sets the kernel audit trail rotation size to.
210- auditreduce(1) now uses stdin if no file names are specified on the command
211 line; this was the documented behavior previously, but it was not
212 implemented. Be more specific in auditreduce(1)'s examples section about
213 what might be done with the output of auditreduce.
214- Add audit_warn(5) closefile event so that administrators can hook
215 termination of an audit trail file. For example, this might be used to
216 compress the trail file after it is closed.
217- auditreduce(1) now uses regular expressions for pathname matching. Users can
218 now supply one or more (comma delimited) regular expressions for searching
219 the pathnames. If one of the regular expressions is prefixed with a tilde
220 (~), and a path matches, it will be excluded from the search results.
221
222OpenBSM 1.0 alpha 11
223
224- Reclassify certain read/write operations as having no class rather than the
225 fr/fw class; our default classes audit intent (open) not operations (read,
226 write).
227- Introduce AUE_SYSCTL_WRITE event so that BSD/Darwin systems can audit reads
228 and writes of sysctls as separate events. Add additional kernel
229 environment and jail events for FreeBSD.
230- Break AUDIT_TRIGGER_OPEN_NEW into two events, AUDIT_TRIGGER_ROTATE_USER
231 (issued by the user audit(8) tool) and AUDIT_TRIGGER_ROTATE_KERNEL (issued
232 by the kernel audit implementation) so that they can be distinguished.
233- Disable rate limiting of rotate requests; as the kernel doesn't retransmit
234 a dropped request, the log file will otherwise grow indefinitely if the
235 trigger is dropped.
236- Improve auditd debugging output.
237- Fix a number of threading related bugs in audit_control file reading
238 routines.
239- Add APIs au_poltostr() and au_strtopol() to convert between text
240 representations of audit_control policy flags and the flags passed to
241 auditon(A_SETPOLICY) and retrieved from auditon(A_GETPOLICY).
242- Add API getacpol() to return the 'policy:' entry from audit_control, an
243 extension to the Solaris file format to allow specification of policy
244 persistent flags.
245- Update audump to print the audit_control policy field.
246- Update auditd to read the audit_control policy field and set the kernel
247 policy to match it when configuring/reconfiguring. Remove the -s and -h
248 arguments as these policies are now set via the configuration file. If a
249 policy line is not found in the configuration file, continue with the
250 current default of setting AUDIT_CNT.
251- Fix bugs in the parsing of large execve(2) arguments and environmental
252 variable tokens; increase maximum parsed argument and variable count.
253- configure now detects strlcat(), used by policy-related functions.
254- Reference token and record sample files added to test tree.
255
256OpenBSM 1.0 alpha 10
257
258- auditd now generates complete audit records for its events, as required for
259 application-submitted audit records in the FreeBSD kernel audit
260 implementation.
261
262OpenBSM 1.0 alpha 9
263
264- Rename many OpenBSM-specific constants and API elements containing the
265 strings "BSM" and "bsm" to "AUDIT" and "audit", observing that this is true
266 for almost all existing constants and APIs.
267- Instead of passing a per-instance cookie directly into all audit filter
268 APIs, pass in the audit filter daemon state pointer, which is then used by
269 the module using an audit_filter_{get,set}cookie() API. This will allow
270 future service APIs provided by the filter daemon to maintain their own
271 state -- for example, per-module preselection state.
272
273OpenBSM 1.0 alpha 8
274
275- Correct typo in definition of AUR_INT.
276- Adopt OpenSolaris constant values for AUDIT_* configuration flags.
277- Arguments to au_to_exec_args() and au_to_exec_env() no longer const.
278- Add kernel versions of au_to_exec_args() and au_to_exec_env().
279- Fix exec argument type that is printed for env strings from 'arg' to 'env'.
280- New OpenBSM token version number assigned, constants added for other
281 commonly seen version numbers.
282- OpenBSM-specific events assigned numbers in the 43xxx range to avoid future
283 collisions with Solaris. Darwin events renamed to AUE_DARWIN_foo, as they
284 are now deprecated numberings.
285- autoconf now detects clock_gettime(), which is not available on Darwin.
286- praudit output fixes relating to arg32 and arg64 tokens.
287- Maximum record size updated to 64k-1 to match Solaris record size limit.
288- Various style and comment cleanups in include files.
289
290OpenBSM 1.0 alpha 7
291
292- Adopted Solaris-compatible format for subject32_ex and subject64_ex
293 tokens, which previously did not correctly implement variable length
294 address storage.
295- Prefer inttypes.h to stdint.h; enhance queue.h detection to test for
296 TAILQ_FOREACH_SAFE(), which is present in recent BSD queue.h's, but not
297 older ones. OpenBSM now builds on some FreeBSD 4.x versions.
298- New event types for extended attributes, ACLs, and scheduling.
299
300OpenBSM 1.0 alpha 6
301
302- Use AU_TO_WRITE and AU_NO_TO_WRITE for the 'keep' argument to au_close();
303 previously we used hard-coded 0 and 1 values.
304- Add man page for au_open(), au_write(), au_close(), and
305 au_close_buffer().
306- Support a more complete range of data types for the arbitrary data token:
307 add AUR_CHAR (alias to AUR_BYTE), remove AUR_LONG, add AUR_INT32 (alias
308 to AUR_INT), add AUR_INT64.
309- Add au_close_token(), which allows writing a single token_t to a memory
310 buffer. Not likely to be used much by applications, but useful for
311 writing test tools.
312- Modify au_to_file() so that it accepts a timeval in user space, not just
313 kernel -- this is not a Solaris BSM API so can be modified without
314 causing compatibility issues.
315- Define a new API, au_to_header32_tm(), which adds a struct timeval
316 argument to the ordinary au_to_header32(), which is now implemented by
317 wrapping au_to_header32_tm() and calling gettimeofday(). #ifndef KERNEL
318 the APIs that invoke gettimeofday(), rather than having a variable
319 definition. Don't try to retrieve time zone information using
320 gettimeofday(), as it's not needed, and introduces possible failure
321 modes.
322- Don't perform byte order transformations on the addr/machine fields of
323 the terminal ID that appears in the process32/subject32 tokens. These
324 are assumed to be IP addresses, and as such, to be in network byte
325 order.
326- Universally, APIs now assume that IP addresses and ports are provided
327 in network byte order. APIs now generally provide these types in
328 network byte order when decoding.
329- Beginnings of an OpenBSM test framework can now be found in openbsm/test.
330 This code is not built or installed by default.
331- auditd now assigns more appropriate syslog levels to its debugging and
332 error information.
333- Support for audit filters introduced: audit filters are dynamically
334 loaded shared objects that run in the context of a new daemon,
335 auditfilterd. The daemon reads from an audit pipe and feeds both BSM and
336 parsed versions of records to shared objects using a module API. This
337 will provide a framework for the writing of intrusion detection services.
338- New utility API, audit_submit(), added to capture common elements of audit
339 record submission for many applications.
340
341OpenBSM 1.0 alpha 5
342
343- Update install notes to indicate /etc files are to be installed manually.
344- On systems without LOG_SECURITY, use LOG_AUTH.
345- Convert to autoconf/automake in order to move to a more portable (not
346 BSD-specific) build infrastructure, and more easy conditional building of
347 components. Currently, the primary feature loss is that automake does
348 not have native support for manual symlinks. This will be addressed in a
349 future OpenBSM release.
350- Add compat/queue.h, to be used on systems dated BSD queue macro libraries
351 (as found on Linux).
352- Rename CHANGELOG to HISTORY, as our change log doesn't follow some of the
353 existing conventions for a CHANGELOG.
354- Some private data structures moved from audit.h to audit_internal.h to
355 prevent inappropriate use by applications and name space pollution.
356- Improved detection and use of endian macros using autoconf.
357- Avoid non-portable use of struct in6_addr, which is largely opaque.
358- Avoid leaking BSD kernel socket related token code to user space in
359 bsm_token.c.
360- Teach System V IPC calls to look for Linux naming variations for certain
361 struct ipc_perm fields.
362- Test for audit system calls, and if not present, don't build
363 bsm_wrappers.c, bsm_notify.c, audit(8), and auditd(8), which rely on
364 those system calls.
365- au_close() is not implemented on systems that don't have audit system
366 calls, but au_close_buffer() is.
367- Work around missing BSDisms in bsm_wrapper.c.
368- Fix nested includes so including libbsm.h in an application on Linux
369 picks up the necessary definitions.
370
371OpenBSM 1.0 alpha 4
372
373- Remove "audit" user example from audit_user, as it's not present on most
374 systems.
375- Add cannot_audit() function non-Darwin systems that wraps auditon();
376 required by OpenSSH BSM support. Convert Darwin cannot_audit() into a
377 function rather than a macro.
378- Library build fixed on Darwin following include file tweaks. The native
379 Darwin sys/audit.h conflicts with bsm/audit.h due to duplicate types, so
380 for now we force bsm_wrappers.c to not perform a nested include of
381 sys/audit.h.
382
383OpenBSM 1.0 alpha 3
384
385- Man page formatting, cross reference, mlinks, and accuracy improvements.
386- auditd and tools now compile and run on FreeBSD/arm.
387- auditd will now fchown() the trail file to the audit review group, if
388 defined at compile-time.
389- Added AUE_SYSARCH for FreeBSD.
390- Definition of AUE_SETFSGID fixed for Linux.
391
392OpenBSM 1.0 alpha 2
393
394- Man page formatting improvements.
395- A number of new audit event identifiers for FreeBSD, Linux, and POSIX.1b
396 events.
397- Remove 'tfm' class, unused in OpenBSM.
398
399OpenBSM 1.0 alpha 1
400
401- Import of Darwin74 BSM drop
402- Use 'syslog' for audit log warnings, rather than echoing to a file in
403 audit_warn.
404- Compile using BSD make infrastructure.
405- Integrate bsm/ include files from Darwin74 XNU drop into OpenBSM.
406- Narrow set of symbols and defines that are exposed in user space: don't
407 compile in code relying on kernel-only types such as 'struct socket'.
408- Add README, including basic build documentation.
409- Compilation of Apple-specific notify and Machroutines now #ifdef __APPLE__.
410- Staticize libbsm global variables to avoid leakage into applications.
411- Add free_au_user_ent() so that au_user_ent's don't have to be leaked.
412- Clean up bogus nul-termination checks in libbsm.
413- Add libbsm API man pages: au_class.3 au_control.3 au_event.3
414 au_free_token.3 au_io.3 au_mask.3 au_token.3 au_user.3 libbsm.3.
415- Add man pages for BSM system calls: audit.2 auditctl.2 auditon.2 getaudit.2
416 getauid.2 setaudit.2 setauid.2
417- Modify various libbsm interfaces to more consistently return 'errno' values
418 on failure.
419- Break out au_close() into constituent parts, allowing records to be written
420 to memory as well as files.
421- Prefix various defines with 'BSM_' to reduce name space pollution.
422- Added audit_internal.h, which can be used by a kernel audit implementation
423 wanting to rely on libbsm components.
424- Build with warnings, and eliminate warnings.
425- Make libbsm endian-independent, storing and reading BSM are big endian
426 (network byte order) rather than native byte order. More consistently
427 print IP addresses using the IP address print routine. These changes
428 make use of sys/endian.h from *BSD; since this isn't present on Darwin,
429 add it to OpenBSM as compat/endian.h, which is used only on Darwin.
430- Import of Darwin80 BSM drop, including 64-bit file IDs, better
431 documentation of private APIs, and bug fixes.
432- White space cleanup.
433- Add audit.log.5, a first cut at a man page documenting the BSM file format.
434- Teach au_read_rec() to recognize stand-alone file tokens, which are present
435 at the beginning and end of Solaris audit trails. Technically, these
436 appear to violate the high level BSM spec, which suggests that all tokens
437 are present in records, but need to be supported.
438- Implement HEADER64, ATTR64, SUBJECT64 token types, which make it possible
439 to run praudit(1) on basic Solaris BSM streams.
440- Switched to Solaris spelling of token names; Darwin spellings are now
441 deprecated and will be removed in a future version of OpenBSM.
442- Adopt Solaris model for representing IPv4 and IPv6 addresses.
443- Prefer C99 types.
444- Attempt to universally adopt the BSD style(9) coding style for
445 consistency.
446- auditreduce(1) now has a usage message.
447- Update support for auditctl(2) system call to support FreeBSD.
448- Add support for /dev/audit as the trigger source on FreeBSD.
449- Add additional event types for Darwin, FreeBSD, and Solaris. Annotate
450 conflicts (there are a few, unfortunately). Correct spellings, comment,
451 sort, etc. These include {get,set}res[ug]id(), sendfile(), lchflags(),
452 eaccess(), kqueue(), kevent(), poll(), lchmod().
453- Relicensed under a BSD license, many thanks to Apple, Inc!
454- Many bug fixes, cleanups, thread safety in the class, control, event,
