Robert Watson 52267f7411 Merge OpenBSM 1.1 alpha 2 from the OpenBSM vendor branch to head, both
contrib/openbsm (svn merge) and sys/{bsm,security/audit} (manual merge).

- Add OpenBSM contrib tree to include paths for audit(8) and auditd(8).
- Merge support for new tokens, fixes to existing token generation to
  audit_bsm_token.c.
- Synchronize bsm includes and definitions.

OpenBSM history for imported revisions below for reference.

OpenBSM 1.1 alpha 2

- Include files in OpenBSM are now broken out into two parts: library builds
  required solely for user space, and system includes, which may also be
  required for use in the kernels of systems integrating OpenBSM.  Submitted
  by Stacey Son.
- Configure option --with-native-includes allows forcing the use of native
  include for system includes, rather than the versions bundled with OpenBSM.
  This is intended specifically for platforms that ship OpenBSM, have adapted
  versions of the system includes in a kernel source tree, and will use the
  OpenBSM build infrastructure with an unmodified OpenBSM distribution,
  allowing the customized system includes to be used with the OpenBSM build.
  Submitted by Stacey Son.
- Various strcpy()'s/strcat()'s have been changed to strlcpy()'s/strlcat()'s
  or asprintf().  Added compat/strlcpy.h for Linux.
- Remove compatibility defines for old Darwin token constant names; now only
  BSM token names are provided and used.
- Add support for extended header tokens, which contain space for information
  on the host generating the record.
- Add support for setting extended host information in the kernel, which is
  used for setting host information in extended header tokens.  The
  audit_control file now supports a "host" parameter which can be used by
  auditd to set the information; if not present, the kernel parameters won't
  be set and auditd uses unextended headers for records that it generates.

OpenBSM 1.1 alpha 1

- Add option to auditreduce(1) which allows users to invert sense of
  matching, such that BSM records that do not match, are selected.
- Fix bug in audit_write() where we commit an incomplete record in the
  event there is an error writing the subject token.  This was submitted
  by Diego Giagio.
- Build support for Mac OS X 10.5.1 submitted by Eric Hall.
- Fix a bug which resulted in host XML attributes not being arguments so
  that const strings can be passed as arguments to tokens.  This patch was
  submitted by Xin LI.
- Modify the -m option so users can select more then one audit event.
- For Mac OS X, added Mach IPC support for audit trigger messages.
- Fixed a bug in getacna() which resulted in a locking problem on Mac OS X.
- Added LOG_PERROR flag to openlog when -d option is used with auditd.
- AUE events added for Mac OS X Leopard system calls.

.Nm getauclassent_r ,
.Nm getauclassnam ,
.Nm getauclassnam_r ,
.Nm setauclass ,
.Nm endauclass
.Nd "look up information from the audit_class database"
.Sh LIBRARY
.Lb libbsm
.Sh SYNOPSIS
.In bsm/libbsm.h
.Ft "struct au_class_ent *"
.Fn getauclassent void
.Ft "struct au_class_ent *"
.Fn getauclassent_r "struct au_class_ent *e"
.Ft "struct au_class_ent *"

.Ft "struct au_class_ent *"
.Fn getauclassnam_r "struct au_class_ent *e" "const char *name"
.Ft void
.Fn setauclass void
.Ft void
.Fn endauclass void
.Sh DESCRIPTION
These interfaces may be used to look up information from the
.Xr audit_class 5
database, which describes audit event classes.
Audit event classes are described by
.Vt "struct au_class_ent" .
.Pp
The
.Fn getauclassent
function
will return the next class found in the
.Xr audit_class 5
database, or the first if the function has not yet been called.
.Dv NULL
will be returned if no further records are available.
.Pp
The
.Fn getauclassnam
function
looks up a class by name.
.Dv NULL
will be returned if no matching class can be found.
.Pp
The
.Fn setauclass
function
resets the iterator through the
.Xr audit_class 5
database, causing the next call to
.Fn getauclassent
to start again from the beginning of the file.
.Pp
The
.Fn endauclass
function
closes the
.Xr audit_class 5
database, if open.
.Sh SEE ALSO
.Xr libbsm 3 ,
.Xr audit_class 5
.Sh HISTORY
The OpenBSM implementation was created by McAfee Research, the security
division of McAfee Inc., under contract to Apple Computer, Inc., in 2004.
It was subsequently adopted by the TrustedBSD Project as the foundation for
the OpenBSM distribution.
.Sh AUTHORS
.An -nosplit
This software was created by
.An Robert Watson ,
.An Wayne Salamon ,
and
.An Suresh Krishnaswamy
for McAfee Research, the security research division of McAfee,
Inc., under contract to Apple Computer, Inc.
.Pp
The Basic Security Module (BSM) interface to audit records and audit event
stream format were defined by Sun Microsystems.
.Sh BUGS
These routines cannot currently distinguish between an entry not being found
and an error accessing the database.
The implementation should be changed to return an error via
.Va errno
when
.Dv NULL
is returned.
