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