Re: [libvirt] [PATCH] util: Call capng_setpid() before using cap-ng

audit is using cap-ng itself since version 2.6.1, and it gets
to initialize the internal state of the cap-ng library before
we call fork(). Because of that, our own use of cap-ng in the
child process ends up attempting to change the capabilities of
the parent process instead of the child process, which fails.
Calling capng_setpid() before using any other cap-ng API
ensures we're altering the capabilities of the right process.
I really don't want to do any hack workaround in libvirt until we've
got feedback from the cap-ng maintainers, as I think it is really
their bug to fix.
