shutdown(2) does not fully shut down socket any more

shutdown(2) does not fully shut down socket any more

[Kees Cook]

Hey all,

I've got a weird regression visible here:
https://bugzilla.kernel.org/show_bug.cgi?id=32832

Can other people reproduce this, and if so, what's going on? Seems like a
kernel bug unless I'm misunderstanding something.

Thanks!

Eric Dumazet will be working on fixing this, see:

http://marc.info/?l=linux-netdev&m=130176733401613&w=2

And Stephem Hemminger already forward that bugzilla entry here
at few days ago.

Ah! Thanks, I didn't noticed that; I saw no activity on the bugzilla entry,
so I thought it hadn't been seen yet.

We bascially do not use kernel.org bugzilla for bug tracking, all
work and discussions occur only here on the netdev list.

So what Stephen Hemminger, Andrew Morton, and others do is simply
forward the bug reports here to the list so we can work on them.

Makes sense, yeah. It'd be cool if the forwarder added a note to the bug
saying "this has been forwarded [here]". Then the reporter would know where
to go look for status updates.

But, regardless, it's being looked at. Thanks!
