Hi,

If I access a file with relative path, the PATH audit message would be
a relative path as well.

I wonder if I can change this behavior without modifying the kernel?

(It seem audit daemon just receive the msg= field from kernel directly)

IIUC, there should be a CWD message to go along with the PATH message.
You should be able to use that to find the absolute path

That is correct. What I do is take the cwd field and concatenate path and then 
run it through realpath(3) to finalize it.
