I'm not ruling anything out, except for the "let's just completely
regenerate every record for each auditd instance".
Paul I am a bit confused about what you are referring to when you say
regenerate every record.
Are you saying that you don't want to repeat the sequence:
audit_log_start(...);
audit_log_format(...);
audit_log_end(...);
for every nested audit daemon?
Or are you saying that you would like to literraly want to send the same
skb to each of the nested audit daemons?
Or are you thinking of something else?
