That might well be the case, but honestly, things like [1] suggest
you're taking a particularly keen interest in the issue, regardless of
whether you personally idle in said channels or not. I mean, honestly,
if you're really that busy, why spend the time?

I'm glad we actually agree on this.

I wouldn't say the bar for copyright is "low", but indeed, it's fair to
point out where such changes came from (if they indeed came directly
from grsec and weren't just re-done; as mostly mechanical changes, it's
entirely expected that they could be). But this comes back to the issue
of making life easy for people. If you're offering nothing beyond your
legal obligations to the GPLv2, making your changes available only in a
format extremely inconvenient to be merged, and lacking fine-grained
attribution, why should people spend their time to meet more than their
bare minimum legal obligations to you in turn?

Ultimately, be nice to people and they'll have more of an incentive to
be nice to you. And an easier technical time getting the right info too.

To be fair, I was expecting you to credit me as an "infosec anklebiter"
in your changelog for my bug report, so kudos to you for actually
mentioning me by name in an otherwise passive-aggressive entry ;)

Is this a legal threat?

Well, if you're (potentially) violating someone else's license, it's no
surprise the might want to be cautious about replying outright...

Suffice it to say I've had better luck communicating with the FSF about
licensing issues.

Being a GCC copyright holder is only required to take *legal action* for
a licensing violation. It is not a requirement to point out a potential
licensing violation. I may not be a GCC copyright holder, but I am a
(minor) Linux kernel copyright holder, as well as heavily depend on both
pieces of software for my professional work and personal usage, and
therefore I have an interest in ensuring that upstream doesn't wind up
in a legal mess because grsecurity decided to license its plugins for
GPLv3'd GCC as GPLv2 in order to supposedly prevent their usage outside
of the kernel through a hilariously convoluted (and misinformed)
licensing hack involving libgcc usage and its exception clause.

And yes, I maintain that in my opinion this approach violates the GCC
license, and that upstream Linux therefore now contains a GCC license
violation, and that possibly nobody cares *in practice*, but that's
still really sad and should be fixed (and the only ways to fix it are
for you/PaX to relicense the code, or for it to be dropped and rewritten).

Victim? Come on Brad, you know full well I'm only trolling you because
you troll everyone else[2]. I really don't mind the attitude; in my
case, I don't think it's hurting anyone but yourself. However, I do know
that your way of handling things has discouraged *other* people less
hardened against this kind of drama from working in infosec and Linux
security in particular, and that hurts the entire community. So, while I
invite you to keep being your usual self towards me, I would appreciate
it if you treated people who *haven't* poked fun at grsecurity on
Twitter nicely. There is no need to make a toxic atmosphere for the
community and for contributors who are just trying to help out.

[2] And I still think it's pretty funny that you could panic grsec with
'script /dev/null </dev/zero' as any user, and that the first bugfix
attempt was not tested and just made it worse.
