decommissioning parisc-linux.org

As Paul noted[1], parisc-linux.org was running a vulnerable
apache which got the attention of HP's security audit team. I've been
doing most of the maintenance of the OS on this machine for a while,
but that has just meant apt-get upgrading when cron-apt told me to for
a few years. Turns out apache-ssl was obsolete (an etch version!), so
no amount of upgrading was going to fix that.

At this point I've removed apache-ssl. I tried installing apache2 to
see if any web pages would magically work - it didn't, so right now
the website is 404 farm :( I didn't spend much time trying to handle
that since.....

parisc-linux.org is running the last stable release of Debian that
supported hppa ('lenny'), and its life is now expired. As such, I
think we really need to migrate the site to another maintained
distribution and/or architecture. I'm willing to help migrate services
for the next month or so - let's just say 2012.03.14 for a good round
(heh) date - after which I plan to halt this system and let HP know
the hardware can be put to other uses. From what I can tell, we
originally installed this system almost exactly 9 years ago - ah,
rememember its predecessor dsl2? Good times. Anyway -

*************************************************************************
*** If you need any data off this machine, now's the time to grab it! ***
*************************************************************************

If you'd like to take over longterm hosting the website/domain, please
get in touch with taggart or I. If you'd like to continue using the
machine and/or HP's network to do the hosting, I can probably find a
contact for you there - though I wouldn't bet on it.

parisc-linux.org issue


Hey I just got notified that parisc-linux.org has a vulnerable apache
server.  I did an apt-get upgrade but it didn't upgrade the server,
and the vulnerability was fixed in lenny's apache2 but not apache "1".

So one question is whether (and who) to move that server to apache2.

A bigger question is what to do since lenny is at end of life.

And who's watching this machine?

That's awesome news!

If you want write access to the wiki to update e.g. this page
http://wiki.parisc-linux.org/TestCases I'd be more than happy to add
your account to the ACL.

Well I have an a500-5x (PA8600) that's doing nothing, but I really
don't have time to do any kind of testing now or in the near future.
I'd be happy to provide access to the hardware tho.

c3700 boot failure (protection ID trap)

I'm trying to test some PCI changes on a c3700, but recent kernels
don't seem to work at all.  74ea15d909b311 (current upstream) and v3.2
both fail as shown below.  I'm using c3000_defconfig (attached for
74ea15d909b311).  Should I expect this to work?

v3.0 gets farther, but then gets into a loop of
__find_get_block_slow() messages like this:

        ...
        md: autorun ...
        md: ... autorun DONE.
        __find_get_block_slow() failed. block=0, b_blocknr=1
        b_state=0x00000020, b_size=4096
        device blocksize: 4096

Fix compile breakage with kref.h

This set of build failures just started appearing on parisc:

In file included from drivers/input/serio/serio_raw.c:12:
include/linux/kref.h: In function 'kref_get':
include/linux/kref.h:40: error: 'TAINT_WARN' undeclared (first use in this function)
include/linux/kref.h:40: error: (Each undeclared identifier is reported only once
include/linux/kref.h:40: error: for each function it appears in.)
include/linux/kref.h: In function 'kref_sub':
include/linux/kref.h:65: error: 'TAINT_WARN' undeclared (first use in this function)

It happens because TAINT_WARN is defined in kernel.h and this particular
compile doesn't seem to include it (no idea why it's just
manifesting ... probably some #include file untangling exposed it).  Fix
by adding #include <linux/kernel.h> to linux/kref.h
