fix PR7059 (partial): mbuf cluster counts were based on counters which
are no longer maintained.
(full fix will involve renaming the now-unused fields in mclstat in mbuf.h)
and the top, and then set the effective gid back to kmem around the call to
kvm_openfiles(). this reduces the time group kmem is available.
- for those above that also allow this, setgid(getgid()) after the call to
kvm_openfiles() to fully revoke priviledges.
- some KNF
- use err(3) over fprintf(3) in some places
Add code to netstat to use libkvm to for kernel variables "mclbytes"
and "msize', and if found, use those for netstat -m rather than
compiled-in defaults.
of long-standing bugs:
- Actually deal with the fact that the kernel ifnet list is
a TAILQ; it just happened to work before.
- Use kvm_openfiles() instead of kvm_open(). The code passed
arguments to kvm_open() as if it were kvm_openfiles(), but
apparently went unnoticed since the prototypes are the same.
Amusing bit: there were XXX's in the code which seemed to
apologize for a verbose libkvm, when it happened to be a
bug in netstat!
