返回类型：void

参数：

类型参数名称
struct audit_buffer *ab
struct aa_ns *ns
struct aa_label *label
intflags
gfp_tgfp
1711  char * name = NULL
1714  AA_BUG(!ab)
1715  AA_BUG(!label)
1717  如果非ached label name is present and visible*@label->hname only exists if label is namespace hierachical或 any visible label is not unconfined the display_mode returns true 则
1719  len等于aa_label_asxprint - allocate a string buffer and print label into it*@strp: Returns - the allocated buffer with the label name
1720  如果len恒等于负1则
1721  AA_DEBUG("label print error")
1722  返回
1724  str等于name
1725  否则
1726  str等于hname
1727  len等于strlen - Find the length of a string*@s: The string to be sized
1729  如果audit_string_contains_control - does a string need to be logged in hex*@string: string to be checked*@len: max length of the string to check则audit_log_n_hex - convert a buffer to hex and append it to the audit skb*@ab: the audit_buffer*@buf: buffer to convert to hex*@len: length of @buf to be converted* No return value; failure to expand is silently ignored
1731  否则Format a string of no more than slen characters into the audit buffer,* enclosed in quote marks.
