Microsoft Only Gave 14,010 Lines of Code

Posted in Courtroom, GNU/Linux, GPL, Kernel, Microsoft, Novell, SCO, Servers, UNIX, Virtualisation, Windows at 5:55 am by Dr. Roy Schestowitz

Source code

Summary: 14,010 lines of actual Linux code, not 20,000 as Microsoft claimed

Microsoft has claimed that its self-serving loadable module for Linux [1, 2, 3, 4, 5, 6, 7], which only advances Microsoft’s interests by polluting the kernel with Microsoft APIs, comprises 20,000 lines of code. Not quite the case, alleges Slated, who has taken a look at the code. Last night he wrote about this patch (managed by a Novell employee by the way):

For those who might want to keep an eye on what the Vole is injecting into the software we use:

http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh..

The consolidated patch is here:

http://www.kernel.org/pub/linux/kernel/people/gregkh…

This is essentially what it adds:

. Microsoft Hyper-V client drivers
. Microsoft Hyper-V virtual storage driver
. Microsoft Hyper-V virtual block driver
. Microsoft Hyper-V virtual network driver

The kernel config options are listed as:

. CONFIG_HYPERV
. CONFIG_HYPERV_STORAGE
. CONFIG_HYPERV_BLOCK
. CONFIG_HYPERV_NET

Oh and BTW, after removing all the non-Microsoft copyrighted code from the above consolidated patch, all the diff declaration headers, and all the empty lines, the number of lines remaining (i.e. the actual code Microsoft generously “contributed”) is 14,010, which is a good six thousand lines short of Microsoft’s claim.

That’s OK though … it’s six thousand fewer lines for me to remove.

Microsoft contributes nothing to Linux, except lawsuits for the most part. Microsoft funded SCO’s lawsuit against Linux (more than once) and right now Microsoft is suing companies for using Linux (also more than once). People who do not yet know all of this ought to wake up and get the facts. Microsoft is always attacking Linux and the code mentioned above is no contribution. If Oracle writes a new file system for Linux (btrfs as the example in mind), then that file system is valuable also to IBM, to H-P and even to us home users. It really enriches Linux. Microsoft’s patch, on the other hand, is helping nothing but Windows, turning GNU/Linux servers into just a virtual appliance running under Windows.

“Microsoft funded SCO’s lawsuit against Linux (more than once) and right now Microsoft is suing companies for using Linux (also more than once).”Whenever Microsoft claims that it “contributes” to Linux, remember that its long-standing CEO, Steve Ballmer, said: “Linux is a cancer that attaches itself in an intellectual property sense to everything it touches.”

Ballmer never retracted that statement and under his leadership Microsoft has also paid SCO, as confirmed in the courtroom under oath. For background about the past month’s SCO developments (a little from June too), see:

More bizarre twists in the SCO case have only led to the point where, according to Pamela Jones, SCO is nearly finished for good.

So those are the various possibilities I see. Do you see any good ones, if you are SCO management? I don’t see even one. If we are marking on a curve, SCO’s suggestion in its letter is the least toxic, but none of the possibilities now are really ideal from SCO’s point of view, and how realistic do you think it is as a suggestion at this late date, considering all that came out in discovery and at the hearing?

I think this may be the very first time in the entire SCO saga where SCO seems to have no really good options on the table that I can see.

And that’s probably why after the hearing on the 27th, I was overwhelmed by the incandescent realization that we had just turned a real corner, one that changes everything, and that we’re in end-game territory, at last.

Microsoft may have moved on from SCO. Now it has Novell at its disposal — the company which is the real owner of UNIX. SCO — like Microsoft and Novell — also used to contribute to Linux before chaos began.

“Pamela Jones [...] has told Infoworld that Microsoft will be the next SCO Group”

    Talk about picking nits.
    I’m willing to bet that most developers look at the line count in their IDE to determine lines of code. I’m also willing to bet that if you take the same approach with other contributions, the lines “actually” contributed would drop as well.
    Does anyone really think that the community opinion of the M$ contribution will drastically change by finding out it was only 14k of “original” code? I doubt it.
    Looks like a slow news day to me.

    Jose_X Reply:

    I agree that this may not change anyone’s opinion, but, for accuracy’s sake, it’s quite off to count the diff program’s existing context lines and the repeating headers as your contribution. I think you can have diff spit our a larger number of context lines. If you do this, you can grow “your” contribution many-fold.

    JohnD Reply:

    Will the code work if you strip out the headers etc? Probably not.
    Is 30k of NEW code more worthy than 10k of new code? I don’t think so.
    When someone spouts off about how many lines of code they’ve written the first thing I wonder is – how much of it is bloat. I’m more impressed by code that works with as few lines as possible than anything else.
    If someone is measuring themselves by LOC, they have cranial-rectal inversion.
    A 5 line patch that fixes 100 bugs is more worthwhile then 50k lines of work around code.

    Jose_X Reply:

    Not C header files but the headings in the diff output.

    Eg, to patch a file, the patch program requires context lines and the file name to find out where to patch in the lines of code. These context lines (existing lines in the kernel) and file name headings are not source code to the kernel but rather are information created by “diff” for use by “patch” to carry out its work of patching the kernel properly. These lines are not written by Microsoft developers but are written by the diff program automatically using the existing kernel.

    I haven’t looked at the diff file but that is what I expect is going on here.

    How many lines of code have /you/ contributed to the Linux kernel, Roy?

    Just curious.

    zatoichi Reply:

    Roy hasn’t contributed any. Roy is an advocate. He “contributes” misinformation and slanted “news”—like this article—to a general reaction of derision amongst the folks who do actually contribute to FLOSS development.

    Roy is about “advocating” “freedom the way Roy tells you to.”

    This is silly, Roy. As Linus has noted, Microsoft is no more “polluting the kernel with Microsoft APIs” by supplying these drivers than Intel is “polluting the kernel with Intel APIs” when they supply power management code for their CPUs.

    The fact is that you’re not in support of “Freedom Zero” here, the freedom to “run the program for any purpose“, Roy: you want to deny the folks who choose to run a Linux distro virtualized on a Windows Server 2008 system the liberty to do so.

    Why is that, Roy? (And do you support the FSF? If so, how, specifically? I’m still waiting to hear an answer on that one…)

  6. Unlawful Regimes Even Hungary and Poland Would Envy

    There’s plenty of news reports about Polish and Hungarian heads of states violating human rights, but never can one find criticism of the EPO’s management doing the same (the mainstream avoids this subject altogether); today we examine how that area of Europe voted on the illegal "Strike Regulations" of Benoît Battistelli

  8. [Meme] IBM Has Paid ZDNet to Troll the Community

    Over the past few weeks ZDNet has constantly published courses with the word "master" in their headlines (we caught several examples; a few are shown above); years ago this was common, also in relation to IBM itself; clearly IBM thinks that the word is racially sensitive and offensive only when it's not IBM using the word and nowadays IBM pays ZDNet — sometimes proxying through the Linux Foundation — to relay this self-contradictory message whose objective is to shame programmers, Free software communities etc. (through guilt they can leverage more power and resort to projection tactics, sometimes outright slander which distracts)



  9. [Meme] ILO Designed to Fail: EPO Presidents Cannot be Held Accountable If ILOAT Takes Almost a Decade to Issue a Simple Ruling

    The recent ILOAT ruling (a trivial no-brainer) inadvertently reminds one of the severe weaknesses of ILOAT; what good is a system of accountability that issues rulings on decisions that are barely relevant anymore (or too late to correct)?

    Just as Benoît Battistelli had a profound misunderstanding of the concept of “social democracy” his mate seems to completely misunderstand what a “social gesture” is (should have asked his father)

    It seems perfectly clear that UPC cannot start, contrary to what the EPO‘s António Campinos told the Council last week (lying, as usual) and what the EPO insinuates in Twitter; in fact, a legal challenge to this should be almost trivial



  21. The EPO’s Overseer/Overseen Collusion — Part IXX: The Baltic States

    How unlawful EPO rules were unsurprisingly supported by Benoît Battistelli‘s friends in Baltic states; António Campinos maintained those same unlawful rules and Baltic connections, in effect liaising with offices known for their corruption (convicted officials, too; they did not have diplomatic immunity, unlike Battistelli and Campinos)

    Financial strangulations for Benoît Battistelli‘s unlawful “Strike Regulations”? The EPO will come to regret 2013…



  25. [Meme] Is Saying “No!” to Unlawful Proposals Considered “Impolite”?

    A ‘toxic mix’ of enablers and cowards (who won’t vote negatively on EPO proposals which they know to be unlawful) can serve to show that the EPO isn’t a “social democracy” as Benoît Battistelli liked to call it; it’s just a dictatorship, currently run by the son of a person who actually fought dictatorship

  30. 'Cluster-Voting' in the European Patent Office/Organisation (When a Country With 1.9 Million Citizens Has the Same Voting Power as a Country With 83.1 Million Citizens)

    Today we examine who has been running the Finnish patent office and has moreover voted in the EPO during the ballot on unlawful "Strike Regulations"; they voted in favour of manifestly illegal rules and for 8.5 years after that (including last Wednesday) they continued to back a shady regime which undermines the EPO's mission statement
