libkvm digging in kernel memory. This is possible since r231506 made getifaddrs(3) to supply if_data for each ifaddr. The pros of this change is that now netstat(1) doesn't know about kernel struct ifnet and struct ifaddr. And these structs are about to change significantly in head soon. New netstat binary will work well with 10.0 and any future kernel. The cons is that now it isn't possible to obtain interface statistics from a vmcore. Functions intpr() and sidewaysintpr() were rewritten from scratch. The output of netstat(1) has underwent the following changes: 1) The MTU is not printed for protocol addresses, since it has no notion. Dash is printed instead. If there would be a strong desire to return previous output, it is doable. 2) Output interface queue drops are not printed. Currently this data isn't available to userland via any API. We plan to drop 'struct ifqueue' from 'struct ifnet' very soon, so old kvm(3) access to queue drops is soon to be broken, too. The plan is that drivers would handle their queues theirselves and a new field in if_data would be updated in case of drops. 3) In-kernel reference count for multicast addresses isn't printed. I doubt that anyone used it. Anyway, netstat(1) is sysadmin tool, not kernel debugger. Sponsored by: Netflix Sponsored by: Nginx, Inc. |
