OpenBSM 1.1 beta 1
- The filesz parameter in audit_control(5) now accepts suffixes: 'B' for
Bytes, 'K' for Kilobytes, 'M' for Megabytes, and 'G' for Gigabytes.
For legacy support no suffix defaults to bytes.
- Audit trail log expiration support added. It is configured in
audit_control(5) with the expire-after parameter. If there is no
expire-after parameter in audit_control(5), the default, then the audit
trail files are not expired and removed. See audit_control(5) for
more information.
- Change defaults in audit_control: warn at 5% rather than 20% free for audit
partitions, rotate automatically at 2mb, and set the default policy to
cnt,argv rather than cnt so that execve(2) arguments are captured if
AUE_EXECVE events are audited. These may provide more usable defaults for
many users.
- Use au_domain_to_bsm(3) and au_socket_type_to_bsm(3) to convert
au_to_socket_ex(3) arguments to BSM format.
- Fix error encoding AUT_IPC_PERM tokens.
