Bug ID: 228831
Summary: netstat -Aan -M no longer reads from the corefile
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: bin
Assignee: b...@freebsd.org
Reporter: j...@freebsd.org
You should be able to run 'netstat' against a corefile using the -M option.
This lets you do things such as display the TCP connections (and the addresses
of their associated control blocks).
In FreeBSD-CURRENT, if you run 'netstat -Aan -M <corefile>', it will return
output. However, the output is taken from the running system, rather than the
coredump. I believe there is no warning that this is the case.
We need to either:
(a) Restore the old behavior (preferred), or
(b) Return an error when a user tries to read from a corefile.
