OpenBSM 1.0
Introduction
OpenBSM provides an open source implementation of Sun's BSM Audit API.
Originally created under contract to Apple Computer by McAfee Research,
this implementation is now maintained by volunteers and the generous
contribution of several organizations. Coupled with a kernel audit
implementation, OpenBSM can be used to maintain system audit streams, and
is a foundation for an Audit-enabled system.
Contents
OpenBSM consists of several directories:
bin/ Audit-related command line tools
bsm/ System include files for BSM
etc/ Sample /etc/security configuration files
libbsm/ Implementation of BSM library interfaces and man pages
man/ System call and configuration file man pages
OpenBSM currently builds on FreeBSD and Darwin. With Makefile adjustment
and minor tweaks, it should build without problems on a broad range of
POSIX-like systems.
Building
Vendor branch import of TrustedBSD OpenBSM 1.0 alpha 5: - Update install notes to indicate /etc files are to be installed manually. - On systems without LOG_SECURITY, use LOG_AUTH. - Convert to autoconf/automake in order to move to a more portable (not BSD-specific) build infrastructure, and more easy conditional building of components. Currently, the primary feature loss is that automake does not have native support for manual symlinks. This will be addressed in a future OpenBSM release. - Add compat/queue.h, to be used on systems dated BSD queue macro libraries (as found on Linux). - Rename CHANGELOG to HISTORY, as our change log doesn't follow some of the existing conventions for a CHANGELOG. - Some private data structures moved from audit.h to audit_internal.h to prevent inappropriate use by applications and name space pollution. - Improved detection and use of endian macros using autoconf. - Avoid non-portable use of struct in6_addr, which is largely opaque. - Avoid leaking BSD kernel socket related token code to user space in bsm_token.c. - Teach System V IPC calls to look for Linux naming variations for certain struct ipc_perm fields. - Test for audit system calls, and if not present, don't build bsm_wrappers.c, bsm_notify.c, audit(8), and auditd(8), which rely on those system calls. - au_close() is not implemented on systems that don't have audit system calls, but au_close_buffer() is. - Work around missing BSDisms in bsm_wrapper.c. - Fix nested includes so including libbsm.h in an application on Linux picks up the necessary definitions.

OpenBSM is currently built using autoconf and automake, which should allow
for building on a range of operating systems, including FreeBSD, Mac OS X,
Vendor branch import of TrustedBSD OpenBSM 1.0 alpha 6: - Use AU_TO_WRITE and AU_NO_TO_WRITE for the 'keep' argument to au_close(); previously we used hard-coded 0 and 1 values. - Add man page for au_open(), au_write(), au_close(), and au_close_buffer(). - Support a more complete range of data types for the arbitrary data token: add AUR_CHAR (alias to AUR_BYTE), remove AUR_LONG, add AUR_INT32 (alias to AUR_INT), add AUR_INT64. - Add au_close_token(), which allows writing a single token_t to a memory buffer. Not likely to be used much by applications, but useful for writing test tools. - Modify au_to_file() so that it accepts a timeval in user space, not just kernel -- this is not a Solaris BSM API so can be modified without causing compatibility issues. - Define a new API, au_to_header32_tm(), which adds a struct timeval argument to the ordinary au_to_header32(), which is now implemented by wrapping au_to_header32_tm() and calling gettimeofday(). #ifndef KERNEL the APIs that invoke gettimeofday(), rather than having a variable definition. Don't try to retrieve time zone information using gettimeofday(), as it's not needed, and introduces possible failure modes. - Don't perform byte order transformations on the addr/machine fields of the terminal ID that appears in the process32/subject32 tokens. These are assumed to be IP addresses, and as such, to be in network byte order. - Universally, APIs now assume that IP addresses and ports are provided in network byte order. APIs now generally provide these types in network byte order when decoding. - Beginnings of an OpenBSM test framework can now be found in openbsm/test. This code is not built or installed by default. - auditd now assigns more appropriate syslog levels to its debugging and error information. - Support for audit filters introduced: audit filters are dynamically loaded shared objects that run in the context of a new daemon, auditfilterd. The daemon reads from an audit pipe and feeds both BSM and parsed versions of records to shared objects using a module API. This will provide a framework for the writing of intrusion detection services. - New utility API, audit_submit(), added to capture common elements of audit record submission for many applications.

You may wish to specify that the OpenBSM components not be installed in the
base system, rather in a specific directory. This may be done using the
--prefix argument to configure. If installing to a specific directory,
remember to update your library path so that running tools from that
directory the correct libbsm is used:
./configure --prefix=/home/rwatson/openbsm
make
make install
LD_LIBRARY_PATH=/home/rwatson/openbsm/libbsm ; export LD_LIBRARY_PATH
You will need to manually propagate openbsm/etc/* into /etc on your system;
this is not done automatically so as to avoid disrupting the current
configuration. Currently, the locations of these files is not
configurable.

Vendor import of OpenBSM 1.0 alpha 9, with the following change history notes since the last import: OpenBSM 1.0 alpha 9 - Rename many OpenBSM-specific constants and API elements containing the strings "BSM" and "bsm" to "AUDIT" and "audit", observing that this is true for almost all existing constants and APIs. - Instead of passing a per-instance cookie directly into all audit filter APIs, pass in the audit filter daemon state pointer, which is then used by the module using an audit_filter_{get,set}cookie() API. This will allow future service APIs provided by the filter daemon to maintain their own state -- for example, per-module preselection state. OpenBSM 1.0 alpha 8 - Correct typo in definition of AUR_INT. - Adopt OpenSolaris constant values for AUDIT_* configuration flags. - Arguments to au_to_exec_args() and au_to_exec_env() no longer const. - Add kernel versions of au_to_exec_args() and au_to_exec_env(). - Fix exec argument type that is printed for env strings from 'arg' to 'env'. - New OpenBSM token version number assigned, constants added for other commonly seen version numbers. - OpenBSM-specific events assigned numbers in the 43xxx range to avoid future collisions with Solaris. Darwin events renamed to AUE_DARWIN_foo, as they are now deprecated numberings. - autoconf now detects clock_gettime(), which is not available on Darwin. - praudit output fixes relating to arg32 and arg64 tokens. - Maximum record size updated to 64k-1 to match Solaris record size limit. - Various style and comment cleanups in include files. This is an MFC candidate to RELENG_6. Obtained from: TrustedBSD Project
