Hi everyone,
First of all this is my first post so please be nice if I'm not using proper
mailing list etiquette or if I ask a stupid question.
I was wondering if anyone knew of how to retrieve a SAVED UID. I know that
you can set/get a real and effective UID. I know you can set a SAVED UID,
but I do not know how to get a saved uid. There is no getsuid() sys call.
The getresuid() system call gets the real, effective, and saved UIDs, but
doesn't return them - so I'm wondering how to actually access the saved UID.
setresuid() puts the saved uid into current->suid, but I can't access that
through user space applications, can I?
It's possible I'm just missing something fundamental about the UID system.
Also, I'm using linux 2.6.16 and really I'm not even sure that this Fedora
Core 5 system even uses saved UIDs.
Any information on the issue would be greatly appreciated.
