[ANNOUNCE] WOLK v2.3 for Kernel v2.6.4

Hi all,

ok, next 2.6-WOLK release. Apply ontop of a vanilla 2.6.4 from kernel.org.

Many thanks to Rik van Ballegooijen and all the other people sending fixes!

... Have fun and a nice weekend :)


BIG NOTE:
- ---------
We now have 5 addons in place, named: grsecurity2, Win4Lin, gobohide, SysTrace
and finally the Staircase Scheduler by Con. I won't merge any of these
patches into mainline 2.6-WOLK in the near future. You have to decide what
addon feature you like to have :) ... Another reason is, I won't break users
of 4g/4g, 4k stacks nor uml-skas3, currently a no-go with grsecurity. Apply
an addon/the addons manually. All five patches are located in the patch itself
in the ./ADDON-patches directory after applying the main patch. Apply as
usual.

wolk2.2 was never released (ok, it was available for some hours but I removed
it because it was broken. Therefore, changelog included too)



KNOWN ISSUES:
- -----------------
- - Loop-AES won't work with per-backing dev unpluggin code in WOLK.
  But fortunately loop-AES coders updated their code. So get the newest
  version before trying loop-AES with WOLK (includes also -mm tree)

Re: [ANNOUNCE] WOLK v2.3 for Kernel v2.6.4

[Shantanu Goel]

[-- Attachment #1: Type: text/plain, Size: 559 bytes --]

Hi Marc,

I took the patch for a spin and found a few glitches.
A patch is attached to fix them.

1. The kernel oops'ed in vt_ioctl due to driver_data
being NULL in the tty.  I copied the relevant fix from
2.6.5-rc2-mm2.

2. I did not configure the in-kernel statd daemon for
NFS.  That caused a BUG() in mon.c:nsm_monitor()
because the handle was never initialized.

3. A typo fix in ipmi/af_ipmi.c.

Thanks,
Shantanu

Re[2]: [ANNOUNCE] WOLK v2.3 for Kernel v2.6.4

[Maciej Soltysiak]

Just a thought...

If it is supposed to be _working_ overload linux kernel, so
maybe Marc should drop the -mm patches as they contain testing
code, which is more prone to bugs than vanilla kernels.

Besides that, WOLK is great with all the stuff you might need in
there, thanks.

Regards,
Maciej
