This has nothing do to with capabilities. > There is nothing in node.js core that lets you manipulate Linux > capabilities like capset() or prctl(PR_CAPBSET_DROP) do - nor will > there be, it's too platform-specific - Why? We have libcap-np which is POSIX. Node has already support for such functions. Like process.getgid(). > but it's trivial to write a > small C++ add-on for it.

The ->clear_caps() method is broken. It's easy to regain all capabilities. He did not honor the capability bounding set. So it is clearly not trivial to write such an add-on. -- Thanks, //richard -- -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
