NAME
       vfs_full_audit - record Samba VFS operations in the system log

SYNOPSIS
       vfs objects = full_audit

DESCRIPTION
       This VFS module is part of the samba(7) suite.

       The vfs_full_audit VFS module records selected client operations to the
       system log using syslog(3).

       vfs_full_audit is able to record the complete set of Samba VFS
       operations:
           chdir
           chflags
           chmod
           chown
           close
           closedir
           connect
           copy_chunk_send
           copy_chunk_recv
           disconnect
           disk_free
           fchmod
           fchown
           fget_nt_acl
           fgetxattr
           flistxattr
           fremovexattr
           fset_nt_acl
           fsetxattr
           fstat
           fsync
           ftruncate
           get_compression
           get_nt_acl
           get_quota
           get_shadow_copy_data
           getlock
           getwd
           getxattr
           kernel_flock
           link
           linux_setlease
           listxattr
           lock
           lseek
           lstat
           mkdir
           mknod
           open
           opendir
           pread
           pwrite
           read
           readdir
           readlink
           realpath
           removexattr
           rename
           rewinddir
           rmdir
           seekdir
           sendfile
           set_compression
           set_nt_acl
           set_quota
           setxattr
           snap_check_path
           snap_create
           snap_delete
           stat
           statvfs
           symlink
           sys_acl_delete_def_file
           sys_acl_get_fd
           sys_acl_get_file
           sys_acl_set_fd
           sys_acl_set_file
           telldir
           unlink
           utime
           write

       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:

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

              o   OPERATION - the name of the VFS operation

              o   RESULT - whether the operation succeeded or failed

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


       This module is stackable.

OPTIONS
       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".

       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.
           Operations can be unset by prefixing the names with "!". The
           default is none operations.

       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.
           Operations can be unset by prefixing the names with "!". The
           default is none operations.

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

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

       full_audit:syslog = true/false
           Log messages to syslog (default) or as a debug level 1 message.

       full_audit:log_secdesc = true/false
           Log an sddl form of the security descriptor coming in when a client
           sets an acl. Defaults to false.

EXAMPLES
       Log file and directory open operations on the [records] share using the
       LOCAL7 facility and ALERT priority, including the username and IP
       address. Logging excludes the open VFS function on failures:

                   [records]
                path = /data/records
                vfs objects = full_audit
                full_audit:prefix = %u|%I
                full_audit:success = open opendir
                full_audit:failure = all !open
                full_audit:facility = LOCAL7
                full_audit:priority = ALERT
