Author can i upload this to security.d.o?

According to bug#231858, currently it's not possible to use
grsecurity on Woody. The latest kernel on woody is 2.4.18, and
apparently some security patches have propagated back into that
kernel that break grsecurity.

Thus, my question: I'd be willing to fix grsecurity wrt woody and
2.4.18. Could I upload the fixed version to security.d.o? Or should
I just declare grsecurity to be unusable on woody and tell people to
get newer, non-woody kernels?

No, you can't. a) because you can't access the queue and b) because
you havent read the security FAQ or developers reference.

Apart from that I'm interested to learn what broke and how it would
be fixed.

Regards,

Joey

I know of both of these, and I have read the related docs. However,
there is no mention of what to do in case that a security update
breaks a different package, which seems to be the case here
(although I have not researched this in full depth).

Now, obviously I don't have access to security.debian.org; I would
have assumed that you'd have read my question whether I can upload
to s.d.o as whether I should bother (and make you guys bother) with
an update, or whether I can just as well forget the update.

It's probably a backport of some of the million of patches in
Herbert's packages.

This is a common source of confusion which often comes up with the
'security' tag in debbugs, but I'm not sure where in the documentation it
should be clarified. Clearly the developer's reference is not the right
place, because there is an entire section on security updates already which
it doesn't seem that you've read (it answers your question about uploading).

Put simply, having a bug in a security-related package is not the same as
having a security-related bug (vulnerability). security.debian.org and DSAs
are used to address the latter, not the former.

If you want to address a severe bug in woody, the correct approach is to
upload to proposed-updates.

I am fully aware of that. However, what happens when
a security-related bugfix causes another packages to become
unusable?

Usually it doesn't; the kernel is a special case because it has so many
source-oriented dependency relationships. Still, proposed-updates seems
like the correct route.

But it won't make it to stable that way, right? Seeing as there is
a new release in testing, I don't see the point...

Why would you say that? That's exactly what proposed-updates is for.

Ah, I was confused. Sorry.

Okay, I will upload the package to proposed-updates.

Thanks for your time and patience.

You've got to be kidding. The only that has changed in woody
is the addition of the mmap/mremap security patches.

The fact that it breaks your package just shows how intrusive
your patch really is.

I don't know what actually causes my patch not to apply. However,
when I fixed it manually, it was really easy, mostly related to
extra comments or slightly changed lines (patch *is* stupid after
all).

So whatever, the patch may be intrusive, but fact is that what's
contained in Woody these days is unusable.
