Subject: confusion regarding the setcap permission
Date: Tue, 14 Oct 2025 05:13:28 +0100	[thread overview]
Message-ID: <DDHR3Y151ZWK.3DNFX6HD9BW9N@gmail.com> (raw)

Hi,

I'm looking at the class process' permission setcap, and I'm a bit
confused as to what it actually grants. The SELinux Notebook describes
setcap as follows:
> Set Linux capabilities of process.
However I'm not really sure what's going on here:
1. What syscall is actually used to set capabilities of a process?
2. What processes is it allowed to set? Assuming that the process is
   started with dac_override (granted both on its executable file and
   the SELinux domain it runs in), would setcap allow it to only set
   dac_override? Would it allow it to set other permissions?

Thanks,
Rahul
