My plan is to update [0] AppArmor profile to fix various DENIED messages in syslog/audit for traceroute, though I am not sure about allowing, or denying, net_admin capability. Looks like traceroute tries to set SO_RCVBUFFORCE and SO_SNDBUFFORCE: setsockopt(4, SOL_SOCKET, SO_RCVBUFFORCE, [8388608], 4) = -1 EPERM (Operation not permitted) setsockopt(4, SOL_SOCKET, SO_RCVBUF, [8388608], 4) = 0 setsockopt(4, SOL_SOCKET, SO_SNDBUFFORCE, [8388608], 4) = -1 EPERM (Operation not permitted) setsockopt(4, SOL_SOCKET, SO_SNDBUF, [8388608], 4) = 0 setsockopt(4, SOL_SOCKET, SO_RCVBUFFORCE, [8388608], 4) = -1 EPERM (Operation not permitted) setsockopt(4, SOL_SOCKET, SO_RCVBUF, [8388608], 4) = 0 setsockopt(4, SOL_SOCKET, SO_SNDBUFFORCE, [8388608], 4) = -1 EPERM (Operation not permitted) setsockopt(4, SOL_SOCKET, SO_SNDBUF, [8388608], 4) = 0 setsockopt(4, SOL_SOCKET, SO_RCVBUFFORCE, [8388608], 4) = -1 EPERM (Operation not permitted) setsockopt(4, SOL_SOCKET, SO_RCVBUF, [8388608], 4) = 0 setsockopt(4, SOL_SOCKET, SO_SNDBUFFORCE, [8388608], 4) = -1 EPERM (Operation not permitted) setsockopt(4, SOL_SOCKET, SO_SNDBUF, [8388608], 4) = 0 setsockopt(4, SOL_SOCKET, SO_RCVBUFFORCE, [8388608], 4) = -1 EPERM (Operation not permitted) setsockopt(4, SOL_SOCKET, SO_RCVBUF, [8388608], 4) = 0 setsockopt(4, SOL_SOCKET, SO_SNDBUFFORCE, [8388608], 4) = -1 EPERM (Operation not permitted) What is interesting, that traceroute developer does not recall changing these values [1]. On Debian Sid and OpenSuse Tumbleweed this issue does not reproduce either. Could it be some Ubuntu-specific patch in the works? It seems that traceroute works OK without net_admin... Thanks!
