- 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.
