You posted in mid December. Guess what, that's a high time for people to
take off for vacations. Also it's a time where a lot of year end work
needs to get done and yes, new code does get pushed to the bottom of the
priority list.

A polite "ping" is allowed if you don't hear back within a week. But
still, this time of year is not the best for new work to be added.

BTW, how much is your company paying David Miller to fix your
submissions? If you're not paying him, don't expect things to get done
at your convenience, or at all.

Seems nobody (besides you) cares at the moment. When someone comes by
and wants this feature, as you so nicely posted it to LKML, it's out
there. They can then clean it up to David's liking, and it will be
added. There is no harm on our side.

You on the other hand need to constantly send patches to your customers.
Seems that the one being hurt by not including these patches is still
you.

You do get credit for the code that you submit. I have people send me
code for a new feature, and I expect them to still maintain it. They
usually have their name at the top of the file as the author.

But the maintainer of the subsystem has the right to control how things
get added to their system, as they are the ones ultimately responsible
for the code out there. If there's a bug, the maintainer is the one that
gets the notice. That's what they maintain, not cleaning up code from
people that want new features. A maintainer is the one that has to make
sure that the code continues to work.

So what?

That code is there. There's a lot of code in the kernel that needs to be
cleaned up. I've done exactly as you did. I copied code, submitted it to
the maintainer, and it was rejected because things have changed since the
time of the code I copied. Did I bitch to the maintainer saying "hey, I
copied this and you should accept it because you have that there." No, I
did not. Actually what I did was fix my patch to what was the right way
to do things, and then I FIXED THE CODE I COPIED!!!


>If you think the CMAC patch was bad then you better call up the authors of the XCBC code and call them out for it too. Stop being hypocritical.

Oh shut up!

The XCBC code is in there today. And yes, if you submitted patches to
clean that code up, I'm sure those will be accepted. But changing code
in the kernel does take work, including removing said code. But that's
still no reason to allow more code that will need to be cleaned up in
the future. Fix it before it gets in.


>

He's not the one calling people lazy. Frankly sir, you're the one being
offensive and a hypocrite.

I did the bitch work of documenting, testing, packaging, development, debugging, and support. It's far far far too common to see OSS developers shy away from the less fun side of software development...

I maintain OSS projects too. And because there's very few people that
contribute, I cherish submissions as well, and will do a lot of the
grunt work that really should be done by the contributor. But the Linux
kernel is much bigger. It changes something like 3000 lines of code a day!

Maintainers do not scale well with such a project, and yes, it's up to
the contributors to take up the slack.

My God, you sound like a 2 year old.

Suck it up, and do the fixes. It's not the time you are worried about,
as you most definitely spent more time bitching to everyone than it
would have taken you to clean up your work.

Because you are the one that cares about it being submitted. If someone
else cares, they'll take your code and fix it, to get it in.

>I agreed that adding the () around the ^/& expressions would be a good idea. However, how is it a good use of my time to re-write the patch (which includes lines of code I didn't write in the first place) for coding styles that are not actually used in the kernel?

It's better on your time than the maintainers. Do not try to compare
your little OSS project to the Linux Kernel. They are two different
beasts.

And that's the perfect time to clean it up.

We can always use more documentation and comments. And actually, the
kernel has been getting better at this regard. New code usually does get
better comments than what is currently in the kernel from years past.

Because honestly I doubt Dave cares about it. Again, how much are you
paying him? You're the one that wants this feature. If someone else
wants it, they'll do this without the 2 year old bitch rant.

Fix the source Luke! It's not a big deal.

And when someone wants it, they will either fix up what you did, or pay
someone to do it for them.

I'd love to sell the idea to my bosses of cleaning up the CryptoAPI/IPsec maybe down the road merging our hardware drivers into mainline but it's not a case I can really make right now. We make due quite fine with a private GPL tree of code but that's the opposite of how this should work.

You did a good job at picking a fight here. I don't see a flaw in the
system. I see a way to get new code in at a higher standard than the old
code, and over time fix the old code so that it catches up with what's
there today. This is what kernel janitors was created for.
