NAME
vfs_full_audit - record Samba VFS operations in the system log

SYNOPSIS

In addition to these operations, vfs_full_audit recognizes the special operation names "all" and "none ", which refer to all the VFS operations and none of the VFS operations respectively.

vfs_full_audit records operations in fixed format consisting of fields separated by '|' characters. The format is:
		smbd_audit: PREFIX|OPERATION|RESULT|FILE

The record fields are:

•   PREFIX - the result of the full_audit:prefix string after variable substitutions

•   OPERATION - the name of the VFS operation

•   RESULT - whether the operation succeeded or failed

•   FILE - the name of the file or directory the operation was performed on

This module is stackable.

OPTIONS

vfs_full_audit:prefix = STRING
    Prepend audit messages with STRING. STRING is processed for standard substitution variables listed in smb.conf(5). The default prefix is "%u|%I".

vfs_full_audit:success = LIST
    LIST is a list of VFS operations that should be recorded if they succeed. Operations are specified using the names listed above.

vfs_full_audit:failure = LIST
    LIST is a list of VFS operations that should be recorded if they failed. Operations are specified using the names listed above.

full_audit:facility = FACILITY
    Log messages to the named syslog(3) facility.

full_audit:priority = PRIORITY
    Log messages with the named syslog(3) priority.

EXAMPLES

Log file and directory open operations on the [records] share using the LOCAL7 facility and ALERT priority, including the username and IP address:
        [records]
	path = /data/records
	vfs objects = full_audit
	full_audit:prefix = %u|%I
	full_audit:success = open opendir
	full_audit:failure = all
	full_audit:facility = LOCAL7
	full_audit:priority = ALERT
