[PATCH] scsi: replace broken specification URL

[PATCH] scsi: replace broken specification URL

[Michael Opdenacker]

The t10.org website containing SCSI-2 draft specifications now requires
to be from a member company to access the documents.

This replaces the now broken link with another public resource
where the specifications can be found.

Just because T10 implemented a pay wall for standards, doesn't mean
they're not still the definitive source.

Adding a note about where you can get free versions is a useful
service, please do, but we have to keep the official links.  To be
honest the Duisberg site doesn't seem useful because it only has the
CAM standard.

The Wayback machine is more useful because it keeps a copy of the site
(with the attached standards) just before the paywall went up:

https://web.archive.org/web/20080828112749/http://t10.org/drafts.htm

But that only really has pre 2008 standards.

Hi James,

Thank you very much for your help...

Understood. I found another location where all the documents seem to be 
available:
http://www.csit-sun.pub.ro/~cpop/Documentatie_SMP/Standarde_magistrale/SCSI/

However, the PDF file from 
https://web.archive.org/web/20080828112749/http://t10.org/ftp/t10/drafts/cam/cam-r12b.pdf 
fails to load at a 130810 byte limit. Other people have reported a 
similar file size issue in the past.

So, should we only that the cam-r12b document can be found from 
http://www.t10.org/t10docs.htm (registration required)?, and tell that a 
copy can be found on 
http://www.csit-sun.pub.ro/~cpop/Documentatie_SMP/Standarde_magistrale/SCSI/?

I'm trying to fix broken links in kernel documentation, which I publish 
on http://free-electrons.com/kerneldoc/ . I have a broken link checker 
for the http://free-electrons.com/ website, and it finds all the broken 
links on http://free-electrons.com/kerneldoc/ . That's a good thing, 
isn't need, but it means I have to get rid of the broken links :)

Thanks again for your help,

Cheers,

Michael.

This link is just a blank page with the CSIT background image when I
follow it. This worked for me though:

As inconvenient as the T10/ANSI restrictions are, we should not be
linking to illegitimate spec repositories.

I agree with you. The documents do not allow copy without permission, so 
the copies we found are illegitimate indeed.

Now I know what patch to send, to get rid of the broken link :)

Thanks,

Michael.

That link really should be http://www.t10.org/drafts.htm. You can't look
up draft specifications using the proposal document search form.

I looked up the original URL when reviewing, and missed the Proposal Heading.
Checked the one Martin referred to and agree with Martin's change as well.
