Photographs of samples of Linux kernel code that SCO claims to be stolen have quickly circulated the web. The images can be viewed on the German language Heise Online [image 1] [image 2].

Links were posted to the lkml and a brief discussion followed. Those interested can find a much lengthier discussion on Slashdot. More specific detail can be found on LWN.net.

compliments of "d1rkinator" from yahoo finance message board:

The code SCO finds offending:

www.heise.de/newsticker/data/jk-19.08.03-000/imh1.jpg

Its location in Linux:

/usr/src/linux-2.4.20/arch/ia64/sn/io/ate_utils.c

And its heritage:

minnie.tuhs.org/UnixTree/V7/usr/sys/sys/malloc.c.html

Ok, SCO: This was easy. Now, show us the other many examples.

For those of you who don't speek greek, the greek text is English and reads:

"As part of the kernel evolution towords modular naming, the functions 
malloc and free are being renamed to rmalloc and rfree.
Compatibility will be maintained by the following assembler code:
(also see free/malloc below)"

What a way of obfuscating their IP. :)

Why the heck is ia64 inventing its own mutex spinlocks?

Sigh.

It's not ia64, it's the SGI platform-specific code...

They can't even copy code to a slide:

	if (size==0)
		return)((ulong_t NULL);

That does not compile...

Nothing new. See this LKML post by Neil Moore and the following thread,
named "Unix code in Linux" from Jun 19:

http://www.ussg.iu.edu/hypermail/linux/kernel/0306.2/1064.html

That code isn't present in 2.5 anymore.
