audit: ignore terminating NUL in AUDIT_USER_TTY messages
AUDIT_USER_TTY, like all other messages sent from user-space, is sent
NUL-terminated. Unlike other user-space audit messages, which come only
from trusted sources, AUDIT_USER_TTY messages are processed using
audit_log_n_untrustedstring().
This patch modifies AUDIT_USER_TTY handling to ignore the trailing NUL
and use the "quoted_string" representation of the message if possible.
