Hello,
These states are needed for user-space to specify ->idiag_states.
Currently both libnl and ss make their own copy of these definitions.
Of course, new sock diag is not just limited to TCP, so we probably
need to rename them to SS_* before exporting them.
I can send a patch if you agree.
Thanks!

One would have to check what are the current best practices for doing
that, i.e. probably this would have to go via
include/uapi//linux/tcp_states.h? Or take the time and create a new
header for the inet_diag.h stuff as this is not TCP specific for quite a
while?
If you could investigate how to properly expose this and then come back
with a patch proposal I think that would ease reviewing :-)

Exactly. The problem is, even in kernel, other protocols already use
these TCP_* states. Maybe we should really define SS_* first, and then
let each protocol define their own based on SS_*, including inet_diag?
