Additionally, you'd need to track *current* state of $CWD, as the absolute
path will change each time a chdir() happens, or if somebody does something
like 'mv . ../../foo'. Particularly evil to track:
cd foo/bar/baz
./myprog &
cd ../
mv baz ..
Where's myprog's ../../bin pointing now? And how would your post processor
know that happened?
I don't think tracking CWD is an issue as it's already right there in
the same audit event as the PATH record. The question is one of
combining data that's already present in a manner which is easier to
process. E.g.:
type=CWD msg=audit(1183402887.758:2083): cwd="/root"
type=PATH msg=audit(1183402887.758:2083): item=0 name="/etc/ld.so.cache"
inode=2362196 dev=fd:00 mode=0100644 ouid=0 ogid=0
rdev=00:00 obj=system_u:object_r:ld_so_cache_t:s0
In this case, /etc/ld.so.cache is already absolute, but there's no
requirement for it to be.
