audit: record AUDIT_ANOM_* events regardless of presence of rules
When no audit rules are in place, AUDIT_ANOM_{LINK,CREAT} events
reported in audit_log_path_denied() are unconditionally dropped due to
an explicit check for the existence of any audit rules. Given this is a
report of a security violation, allow it to be recorded regardless of
the existence of any audit rules.
To test,
mkdir -p /root/tmp
chmod 1777 /root/tmp
touch /root/tmp/test.txt
useradd test
chown test /root/tmp/test.txt
{echo C0644 12 test.txt; printf 'hello\ntest1\n'; printf \\000;} | \
scp -t /root/tmp
Check with
ausearch -m ANOM_CREAT -ts recent
