I'm wondering if it would be better to capture the whole cred structure.
Similar to io_register_personality(), which uses get_current_cred().
Only using uid and gid, won't reflect any group memberships or
capabilities...
Hmm, I thought about that, but was
under an impression that with get_current_cred()
you only increment a refcount.
But I guess the trick here is that due
to an RCU machinery, you can actually
get your local copy if someone else
changes it?
I'll try what you say, thanks.
