I've found a strange phenomenon associated with capabilities. It seems to= be a quantum like. when I run (as root) delfin:~# /usr/sbin/execcap '=3D cap_net_raw=3Dep' /bin/sh -c 'getpcaps $= $' Capabilities for `2438': =3Dep cap_setpcap-ep I don't know what really happens to those capablities I zero. And I can't= really figure out for when I try the wavefunction collapses delfin:~# strace -o /dev/null /usr/sbin/execcap '=3D cap_net_raw=3Dep' /b= in/sh -c \ 'getpcaps $$' Capabilities for `2461': =3D cap_net_raw+ep Strange isn't it? Does it mean that processes can't really drop their pri= vileges? please CC. --=20 By=C5=82o mi bardzo mi=C5=82o.
