Programming

Hello,

I'm trying to create a pset with pset_create() and I get errno=1. In the man of pset_create() is written that this happens when the {PRIV_SYS_RES_CONFIG} privilege is not asserted in the effectvie set of the calling process.
Is the problem indeed in the privilege?
Now I'm trying to add this privilege to the priv set of my process, but I don't succeed.
setppriv(PRIV_ON, PRIV_SYS_RES_CONFIG, NULL) - won't work. It returns errno 22 (op or which out of bounds). When I create a temporary set: priv_set_t *set and pass it to the syscall instead of NULL, it also fails.

Please help me with this.
Thanks!

I wouldn't expect a process to be able to give itself privileges unless it's privileged in the first place.

You need to run usermod or smrole to grant the user priv, before you try to run the code.
Alternatively, you can invoke the code as setuid, giving the process the 0 uid, which by default grants all privs while the image is running.
