As a side note I'm concerned there may be places in the user audit
code which treat string data as null terminated (at least that is my
recollection).
Yes, auditd adds a NUL terminator to the audit record, and then treats
it as a regular NUL-terminated string; if the audit record contains an
embedded NUL byte, the rest of the record is discarded by auditd.
In every case where this occurs (kernel or user space), the field values are
expected to be encoded to prevent it from being discarded.
