Vendor import of OpenBSM 1.1 alpha2, which incorporates the following changes since the last imported OpenBSM release: 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 beingguments 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.

Vendor import of OpenBSM 1.1 alpha4, which incorporates the following changes since the last imported OpenBSM release: OpenBSM 1.1 alpha 4 - With the addition of BSM error number mapping, we also need to map the local error number passed to audit_submit(3) to a BSM error number, rather than have the caller perform that conversion. - Reallocate user audit events to avoid collisions with Solaris; adopt a more formal allocation scheme, and add some events allocated in Solaris that will be of immediate use on other platforms. - Add an event for Calife. - Add au_strerror(3), which allows generating strings for BSM errors directly, rather than requiring applications to map to the local error space, which might not be able to entirely represent the BSM error number space. - Major auditd rewrite for launchd(8) support. Add libauditd library that is shared between launchd and auditd. - Add AUDIT_TRIGGER_INITIALIZE trigger (sent via 'audit -i') for (re)starting auditing under launchd(8) on Mac OS X. - Add 'current' symlink to active audit trail. - Add crash recovery of previous audit trail file when detected on audit startup that it has not been properly terminated. - Add the event AUE_audit_recovery to indicated when an audit trail file has been recovered from not being properly terminated. This event is stored in the new audit trail file and includes the path of recovered audit trail file. - Mac OS X and FreeBSD dependent code in auditd.c is separated into auditd_darwin.c and auditd_fbsd.c files. - Add an event for the posix_spawn(2) and fsgetpath(2) Mac OS X system calls. - For Mac OS X, we use ASL(3) instead of syslog(3) for logging. - Add support for NOTICE level logging. OpenBSM 1.1 alpha 3 - Add two new functions, au_bsm_to_errno() and au_errno_to_bsm(), to map between BSM error numbers (largely the Solaris definitions) and local errno(2) values for 32-bit and 64-bit return tokens. This is required as operating systems don't agree on some of the values of more recent error numbers. - Fix a bug how au_to_exec_args(3) and au_to_exec_env(3) calculates the total size for the token. This bug resulted in "unknown" tokens being printed after the exec args/env tokens. - Support for AUT_SOCKET_EX extended socket tokens, which describe a socket using a pair of IPv4/IPv6 and port tuples. - OpenBSM BSM file header version bumped for 1.1 release. - Deprecated Darwin constants, such as TRAILER_PAD_MAGIC, removed.

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 1.1 alpha 3 - Add two new functions, au_bsm_to_errno() and au_errno_to_bsm(), to map between BSM error numbers (largely the Solaris definitions) and local errno(2) values for 32-bit and 64-bit return tokens. This is required as operating systems don't agree on some of the values of more recent error numbers. - Fix a bug how au_to_exec_args(3) and au_to_exec_env(3) calculates the total size for the token. This bug resulted in "unknown" tokens being printed after the exec args/env tokens. - Support for AUT_SOCKET_EX extended socket tokens, which describe a socket using a pair of IPv4/IPv6 and port tuples. - OpenBSM BSM file header version bumped for 1.1 release. - Deprecated Darwin constants, such as TRAILER_PAD_MAGIC, removed.

Add libauditd library that is shared between launchd and auditd. - Add AUDIT_TRIGGER_INITIALIZE trigger (sent via 'audit -i') for (re)starting auditing under launchd(8) on Mac OS X. - Add 'current' symlink to active audit trail. - Add crash recovery of previous audit trail file when detected on audit startup that it has not been properly terminated. - Add the event AUE_audit_recovery to indicated when an audit trail file has been recovered from not being properly terminated. This event is stored in the new audit trail file and includes the path of recovered audit trail file. - Mac OS X and FreeBSD dependent code in auditd.c is separated into auditd_darwin.c and auditd_fbsd.c files. - Add an event for the posix_spawn(2) and fsgetpath(2) Mac OS X system calls. - For Mac OS X, we use ASL(3) instead of syslog(3) for logging. - Add support for NOTICE level logging.
