Return to systat.h CVS log

Up to [local] / src / usr.bin / systat

Switch the netstat view of systat to use the same kvm_getfiles()
function similar to netstat(1). The output still shows the same
info but may be a bit differently sorted. Also it will now show
connections that are not UDP or TCP.  This was the last bit of
systat that needed kvm access and so now systat no longer needs
to be setgid kmem.
With this commit OpenBSD is officially setgid kmem free and an
almost 10 year journey finally comes to an end.
