notes since the last import: OpenBSM 1.0 alpha 11 - Reclassify certain read/write operations as having no class rather than the fr/fw class; our default classes audit intent (open) not operations (read, write). - Introduce AUE_SYSCTL_WRITE event so that BSD/Darwin systems can audit reads and writes of sysctls as separate events. Add additional kernel environment and jail events for FreeBSD. - Break AUDIT_TRIGGER_OPEN_NEW into two events, AUDIT_TRIGGER_ROTATE_USER (issued by the user audit(8) tool) and AUDIT_TRIGGER_ROTATE_KERNEL (issued by the kernel audit implementation) so that they can be distinguished. - Disable rate limiting of rotate requests; as the kernel doesn't retransmit a dropped request, the log file will otherwise grow indefinitely if the trigger is dropped. - Improve auditd debugging output. - Fix a number of threading related bugs in audit_control file reading routines. - Add APIs au_poltostr() and au_strtopol() to convert between text representations of audit_control policy flags and the flags passed to auditon(A_SETPOLICY) and retrieved from auditon(A_GETPOLICY). - Add API getacpol() to return the 'policy:' entry from audit_control, an extension to the Solaris file format to allow specification of policy persistent flags. - Update audump to print the audit_control policy field. - Update auditd to read the audit_control policy field and set the kernel policy to match it when configuring/reconfiguring. Remove the -s and -h arguments as these policies are now set via the configuration file. If a policy line is not found in the configuration file, continue with the current default of setting AUDIT_CNT. - Fix bugs in the parsing of large execve(2) arguments and environmental variable tokens; increase maximum parsed argument and variable count. - configure now detects strlcat(), used by policy-related functions. - Reference token and record sample files added to test tree.

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
OpenBSM is currently built using autoconf and automake, which should allow
for building on a range of operating systems, including FreeBSD, Mac OS X,
and Linux. Depending on the availability of audit facilities in the
underlying operating system, some components that depend on kernel audit
support are built conditionally. Typically, build will be performed using
./configure
make
To install, use:
make install
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.
