Linux Sourcecode To Minitar Access Point
mcbridematt writes "Minitar sells a rebadged Edimax Linux based-802.11b Access Point in Australia (no FCC ID yet) for a relatively cheap price (under AUS $100 in places). These access points are based around the Realtek 8181 wireless-system-on-chip design, have 8MB flash rom, and run a 2.4 series Linux kernel. After requests from the community to get the kernel sources, which resulted in a incomplete sourcecode release, we finally have (allegedly) complete and GPL compliant Linux kernel sources for this fine Access Point. Special thanks to chuna, serialmonkey and screwball at Minitar for making this happen, especially after they ran into arguments with their OEM and Realtek over this." From the attached forum discussion, you can see there's disagreement about whether the source code release is as complete as it should be.
Who is actually going to care? Will any of you buy this product now, and hack around with the source?
Before I kick myself in the arse over my usage of "full" in this story, there ain't any wireless code in there. It appears to be for the purpose of getting Linux to run on the damn thing. (Imagine a Beowulf cluster of these AUS $100 things blah blah..)
:(
The RTl8181 driver for Linux has been a seperate binary driver for some time
...is kindof a cool thing one can do if able to update the flash memory on accesspoints.
Check out http://reseaucitoyen.be/index.php?OpenWrt (french) which is a project to run a olsr implementation (www.olsr.org) in a LinkSys-Wrt54G which also runs Linux.
But big deal. The source is going to be 99.8% unchanged from the previously public version, and the 0.2% remaining is just going to be bootstrap code and code to work around bugs in the specific hardware, etc. Further, I bet nobody actually does anything interesting with it now that they've got the source. After all, the HW's only good for one thing, and it already does it.
Suing every commodity router builder that comes down the pike with a product like this, which has essentially zero software value added in it, is just going to make some manufacturers squeamish about using Linux inside. And I want them to use Linux, because I, as a consumer, would rather have that than the lower quality, higher cost alternatives that exist.
Looking at it another way, if the OSS community sues over these dinky issues, where they get no great new software to show for it, they'll lose out on luring some big fish to use OSS plus their own super-duper-multimedia-software, which the community could then sue for and actually get something out of it.
P.S. For those that say "but we might get a driver for the buggy chipset that we've only got a buggy closed source driver for now" - will you listen to yourselves? Support another chipset vendor, you twits!
Everybody's a libertarian 'till their neighbour's becomes a crack house.
Link to the product at NewEgg.
Knowledge is power. Knowledge shared is power multiplied.
" Don't get me wrong. I think that, under GPL, people are fully entitled to ask for the source for this thing."
Then why rant about it? Either they are, or they aren't. There's no middle ground.

Kind of hard to tell without the source code, now isn't it? Besides your "it already does it" applies as much to the big battles as does the small.

The reasons NOT to do something will always outnumber to reasons to. And I wouldn't call the firmware of "essentially zero software value" since in it's absence the hardware is of no value whatsoever.

I wasn't aware that having control over you hardware was a "dinky" issue. Thanks for the heads up.

P.S.S. Running away from a problem will not only not solve that problem, it makes you weak when it comes to dealing with bigger problems.
You are wrong on that part. So what if the code on your product is GPL'ed? You are still SELLING the HARDWARE, all you are doing is allowing people to modify it at will. This will in fact INCREASE your sales to the computer community as they can now roll out their own custom solutions and not be bogged down by the compiled software.
The GPL is not a new idea, it's principle is based in history. People thoughout the centuries have written down their scientific breakthroughs, finds and other discoveries. They believed that by sharing what they found and developed would help the world. They are still credited with the finds, but now everyone has access to them. Why are computers so different? Because money and companies are involved. Stupid managers and officers all see, Propritary CODE MUST NOT SHARE, when in fact if they made good products, GPL'd the code they would make money.
You see even though you GPL the code does not mean that your competitor can steal it, they too are bound by it and must make their changes public, which in turn helps you. WHOA!!! The GPL is a idea based on the sharing of knowledge for the benefit of the whole world.

"This is a prime example of how the GPL is going to continue to hurt Linux. Going after a company like this for violating Linux's overly-restrictive license is not going to promote widespread corporate adoption - rather, it will push them towards proprietary solutions."
You wish us to accept your premise? OK. accept this one then. Going after customers for violating overly restrictive EULA's (BSA) is going to hurt proprietary chances in the marketplace, and push customers towards OSS solutions.
Now I leave it to you to match reality with the above.
Eventually people will get the message and either build/buy propretary solutions or adhere to the licenses of the Free Software they choose. Someone should have known that putting a statically compiled in wireless driver into a commercial product means one of two things, yank as a mistake on sight and say sorry, or release the source. If you build a product on Free Software, you should understand what you are doing and if you are not planning on releasing everything you do you had better be real careful you don't contaminate what you want to "keep"! I see it as a good thing, as it reinforces the "community" element of Free Software and reassurres people who might put serious work into Free Software that it won't be hijacked by others who won't follow the rules (well don't know what would happen with GPL violations/violators in China, for example, at present).
BTW I only want Linux to gain widespread acceptance if it is still Free, the video card market is where this battle is really being fought at present though with Daniel Stone's announcment that XFree86 has been forked (I submitted a first story to slashdot about this 9 days ago and it's still pending), not once but twice (by X.org and freedesktop.org) perhaps a shake-up is coming.
Never underestimate the dark side of the Source
"and that's what Linux people want, right?" Contrary to what those companies would like you to believe, many of the "Linux people" just want an operating system that they can fiddle with and can modify freely. It isn't about acceptance, or profit, or popularity contests, or usability. If keeping software like this free in every instance isn't your priority, then go use one of the wonderful BSD licensed operating systems and stop telling everyone else what the purpose of the linux kernel is. Linux isn't about sacrificing the freedom Linus put his kernel under (along with every person who ever contributed to it) for some semblance of acceptance and self-esteem.
Don't be too proud of this technological terror you've constructed. The ability to block G4T0r spyware crap is insignificant next to the power of the Source.
Don't try to frighten us with your coder's ways. Your sad devotion to that irrelevant OS has not helped you sell routers; we all know that Linux is a niche market
I find your lack of faith disturbing.
Remember, the open source will be with you, always
Listen to Vader
Rubbish. It's a prime example of how a corporation saw something for nothing, took it, and is renegging on the deal it engaged it. Few people, if any, in the Linux community got anything out of them using our work, but they got a complete operating system that would have otherwise cost them a shitload to develop or buy. You can bitch about the GPL being restrictive if you want, but all that's really being asked is to give as well as take. Except instead of just asking nicely, it's a legal requirement.
I'm guessing your not a Linux user or contributor, judging by your last remark. Most of us don't give a toss about Linux widespread acceptance, we just want Linux to work better for us - if others like it too, then that's a bonus. We're certainly not doing it to make other companies wealthy on our backs with nothing in return, even if it is a token gesture in comparison.
Forget thrust, drag, lift and weight. Airplanes fly because of money.
1. Company X makes the guts of one of these routers or access points. They modify GPL'ed software, and put it on ROM in the device.
2. Company X sells these things to OEMs, who put it in boxes, add their applications in a separate ROM, and sell it to customers. Company Y is one of these OEMs.
3. Company X includes the full machine readable source of the GPL'ed ROM with the board they sell to company Y. Note: Company X has completely satisfied their GPL obligation. They are completely off the hook as far as anyone who acquires the software from company Y is concerned.
4. Now it gets interesting. Company Y takes the board with the ROM, and sells it to an end user. Note that company Y is allowed to do this without the permission of the copyright holder, because of the first sale doctine (see footnote).
5. Because company Y didn't do anything other than what is allowed by copyright law, they are under no GPL obligation to provide ROM source to the end user.
6. Note the end result: no one has a GPL obligation to provide source to the end user! Company X satisfied all their GPL obligations in their dealings with company Y, and company Y distributed in a way that falls outside the GPL.
Note: this isn't as big a loophole in GPL as it might seem, since it only applies to things like ROMs, where someone like company Y receives a particular copy, and distributes that particular copy to the end user.
Footnote: the fair use doctine, codified at 17 USC 109 if I recall correctly, basically states that the legal owner of a particular copy of a copyright work can sell that copy, without that violating that copyright owner's exclusive right to distribute or authorize distribution of the work. This is what allows used bookstores, for example. Without the first sale doctrine, every time a book changed hands, it would require the publisher's permission!
This is also what lets you sell a used embedded device on eBay without incuring any GPL obligation if it turns out the device uses GPL'ed code, so I wouldn't say this loophole in GPL is a bad thing. If you just go down to BestBuy and buy a router, you should be able to resell that without worrying about whether or not the manufacturer used any GPL'ed code in the thing.
I call bullshit on this one. No one forced this corp to use Linux - they could have easily bought or licensed or developed an OS other than Linux.
But they CHOSE to use Linux. And in doing so, they adopted the GPL.
Release the damn code. I released mine, now it's your turn.
If you don't - then here's a tip - yank that product, and reissue it with some other OS. If you don't, then suffer the consequences you assholes.
The GPL serves a purpose (though I'm not sure what)
Perhaps you should read it some time. The GPL is a license that software authors employ to grant others the rights to use and modify their software codes. In other words, if I spend a year developing some software, I can then distribute it under the GPL. The specific advantage of the GPL as compared to BSD-style licenses is that it gives other free software developers (who I presumably share some common interests with) an advantage over commercial competitors who might take my hard work and turn it into a commercial product that competes with me.
Companies developing routers have a simple choice: write the software from scratch, buy commercial software, or use free software. If they buy commercial software, they must respect those license conditions imposed. If they use free software, they must also respect the license. If it's GPL, that means making the source code available.
A business has no right to take GPL software (representing, I remind you, a significant investment of someone's time) and break the license. They should do what everyone else has to do in business: invest themselves in their own products.
Ceci n'est pas une signature
The real issue here (I think), is that it would hurt Realtek more in the long run when there is no sourced driver available for their own hardware.
Without acceptance into Linux, people are more likely to avoid their hardware when choosing a Linux set-up.
So who's the real loser going to be in this situation?
Answer: Realtek, and their own customers!

Doesn't everyone require the publishers permission when they sell their books? Oh wait...I forgot, this is 2004. I'll repost in a few years when the preceding statement is true. :-)
Yah, but the problem is that under copyright law, they're not allowed to make that restriction in this case - I can resell a book without having permission to copy it at all. The GPL says "You don't have permission to copy it without including the source", but first sale says you don't need any permission. That's the point - Someone could say to company Y "You don't have the right to distribute this GPLed software without source!" and company Y's response would be "I'm not distributing it. I'm selling it."
It is an interesting loophole, and it is a loophole. The easy way to see this is just consider that copyright gives you no rights to copy and distribute a copyrighted work you bought without a license. But first sale doctrine does allow you to sell something you bought.
The Minitar AP is hardly the first AP for such an issue to surface. My Linksys WRT54G wireless router is also Linux based, which has been great as it has given birth to some interesting firmware and OS variations.
The concern for drivers isn't as big as you would think. Why spend AU$60 or 70 bucks on a realtek wireless card when for AU$80 (in our recent Melbourne Wireless bulk buy) you can have a complete, standalone, managed network device. Around our community wireless group, these devices are very popular for their possibility of expanding their functionality to include routing and fault tolerence technologies at a fraction of the cost of a commercial solution which we neither want or can afford. This is also helpful as we can implement peer-to-peer IBSS mode which is better suited for point to point links. Additionally, it allows us to build a wireless node for $80 an interface (excluding antenna and cabling) simply by pkugging in an extra device into a switch or hub.
I believe the common issue with releasing wireless drivers for open sourced OS's is that the cards can be reprogrammed to use wireless channels which may violate their telecommunications (eg, austel, FCC) certification by operating in frequency ranges of which they are not permitted.
I think that due to the cost of APs. vs using a PC as an AP these days, especially in running costs, that the protection of infrastructure-mode AP capabilities is really pointless anyway.
Since these linux drivers are responsible for so much revenue to these big companies, they would much rather gobble you up for a couple dozen million (chump change really), than deal with the publicity of a lawsuit.
Of course you need to have a backup plan incase they don't bite. You need to protect your "IP" so you issue press releases like you were the AP, telling anyone and everyone that you are suing these evil corporations, and you have expensive lawyers. Sell your stock like mad, when dumb people buy your story..
If they ask "what IP do you have?" Loudly shout "errr, umm, Look at that monkey over there!", and make sure that by the time they turn back around, your expensive lawyer is there with lawsuit in hand..
I don't need an MBA or a Law Degree, everything I need to know i learned from Slashdot and the litigious bastards.
What are we going to do tonight Brain?
By that logic, an OS without memory protection or preemptive multitasking is not to be blamed for lock ups - applications are.
Maybe device drivers a bit different because some operations can cause a hardware malfunction that will bring down the machine no matter what the OS does. But I bet most crashes are due to more trivial reasons - a driver corrupting kernel memory, waiting forever for a failed operation, taking 100% of CPU time an so on.
There is no excuse why device drivers can not have their own protected memory space, swap to virtual memory, only be able to access mapped memory and I/O ports they are supposed to use, communicate with the kernel through regular system calls and receive queued interrupts by reading from sockets. There is no reason device drivers can not be implemented in Java.
Have real-time concerns or chicken-and-egg problems (disk drivers will have a hard time using virtual memory)? Fine, implement that driver - or just the portion that needs to be real time - in kernel. Just don't tell me my Palm USB driver needs to corrupt kernel memory and crash the system.
Reading that page again, it says that it's got 8mb of RAM rather than ROM. 1mb ROM doesn't sound like enough to do anything cool
Should be enough to tftp something cool from elsewhere on your network.
There is no sanctuary. There is no sanctuary. SHUT UP! There is no shut up. There is no shut up.
What we need is a new law that makes it illegal for hardware manufacturers to keep driver details secret. If you want to sell me a fancy wireless adaptor, graphics card, sound card or whatever, fine; but you have to give me all the information I need to write a driver for anything that I might want to interface to it.
It used to be so, back in the days when a printer came with a big thick manual explaining how to do various textual and graphical effects, even pulse timings and voltages for the interface. And everyone thought that information was part of the operating instructions. Sometime between then and now, it went sour; probably we didn't notice, but documentation went from hacker-friendly, to (non-hacker)-friendly, to non-(hacker-friendly). Nowadays, it seems printer manuals just say "plug in the USB cable and install the Windows software" -- and manufacturers are treating the important stuff like how to fire the second "red" nozzle down as though it were some sort of nuclear secret.
Well, it isn't. If you buy a piece of hardware you have every right to make use of that hardware, and if the manufacturer will not tell you how to do so then they are obstructing your enjoyment of your own property. At the very least, the owner of a particular device should -- by sole virtue of ownership -- be automatically privy to any "secret" it may contain; ideally, such information would be in the public domain by law.
And sod the whingeing about "competitors having access to your 'proprietary information'". Your competitors already pay people to reverse-engineer your products, and you will get access to their "proprietary information".
Je fume. Tu fumes. Nous fûmes!
Right idea, wrong focus. It's not that we got a cheap router out of the deal. They got a cheap OS out of the deal. Linux is equivalent to millions of dollars in saved licensing fees. This gives them a huge market advantage over their competition. Their only obligation was to make all modifications available under the terms of the GPL.
Except they reneged on their obligations. They were happy to profit from Linux but they're not so keen to pay the pricetag. Too bad for them. If they want to keep their code secret they can go pay $20/device for an embedded VxWorks license like all the other companies do. They deserve no sympathy and no defence. Linux isn't a free-for-all; it's a give-as-you-receive.
They should have used BSD if they wanted to plunder without giving back.
Wrong.
There's really nothing more to add.
Who wants minitar, when you can get GNU tar with a lot more options? Even GNU tar can do backup over network! There might even be a --wireless-net=yes in the next release.
