You can find all on http://www.user-mode-linux.org/~blaisorblade/.
The SKAS3/2.6-v7 was already released, but I probably forgot to announce it.
So I'm announcing it now.
Changes in SKAS:
* echo 0 > /proc/sysemu on the guests works fine, finally!
Changes in both 2.6.9 and 2.4.27:
they run fine on 2.6.9 host kernels, without hanging at the exit.
Changes in 2.6.9 only:
included a large chunk of JDike tree (excluding all x86_64 related patches),
and all the latest security patches from Bodo Stroesser; also it includes the
-V7 skas patch in it.
Actually, however, to do this I had to include big, invasive patches from Jeff
Dike's tree. I've done it because it's needed and because Bodo Stroesser
worked with the incrementals very fine.
Changes in 2.4.27 only:
It's based on a fork from the official 2.4.24-1; the patches I've included
come almost totally from there, but I dropped all the hostfs rewrite. I also
included some incrementals, the one I thought safe.
Also, you can find on the page the instructions to avoid the "hwclock hang" in
TT mode. I found the faulty patch, but it needs a more worse bug, which
affects everyone running in TT mode on a 2.6 host, so it's included. You can
revert the patch if you want, and if you have to run it on a 2.4 host. I sent
a message about this about a week ago, but I got no answer.
Distribution:
* the patch are also in split-out form, both web-browsable and tarballed.
* md5sums are available (to test with "md5sum -c *.md5").
Any testing and report is welcome.
Bye

Correction 1: for 2.6.9-bb1 (I maybe wasn't clear) and 2.4.27-bs1.

Which UML version, please? 2.4 or 2.6? I tested the 2.6 one (make sure to do a
"make clean ARCH=um" before recompiling), but not the 2.4 one yet, maybe.
However, if you have this problem, please make sure you're using Uml 2.6.9-bb1
and compiling it from a clean tree.
Also, try to see if it is the same kind of hang (which should be solved) or
another one (which is, indeed, possible to happen).

I just compiled a 2.6.9 + uml-2.6.9-bb1.patch.bz2 guest kernel, but
it hangs on my system immediately after:
...
Initializing software serial port version 1
Using anticipatory io scheduler
/dev/ubd/disc0: unknown partition table
Initializing stdio console driver
My host kernel is 2.6.9-skas-v7 on Debian unstable. My previous guest
kernel (2.6.9 + JDike Incrementals + ptrace() hang patch) works
flawlessly under the same conditions.
The http://www.user-mode-linux.org/~blaisorblade/ site appears to be
inaccessible at this moment. When the site comes back up,
I will try to play with the broken out version of the 2.6.9-bb1
patches to see if the cause of this problem can be isolated.

OK. The problem was due to user error in not setting the
configuration option CONFIG_FD_CHAN properly. When this option is
set to "Y", everything appears to work fine again.
Just in case anyone else runs into this, here's what happened. In the
UML Incremental Patches site, the no-chans patch had dealt with this
possible problem by removing the CONFIG_FD_CHAN configuration option
from the config file. However, the bb1 patch does not contain the
no-chans patch, so it requires that the CONFIG_FD_CHAN option be put
back. For some reason, CONFIG_FD_CHAN defaulted to "N" when prompted
for on the screen as a new configuration option while doing a "make
oldconfig ARCH=um" using an existing config file.

I want to get this clear:
Every older guest UML kernel will hang on exit on 2.6.9 hosts from now
on, and there's nothing to fix it but to update the guest UML patches?
This is a nasty limitation in general - because it means that on the
update to 2.6.9, every kernel binary needs to be updated - and finding
rock solid versions of kernels + UML patches is not a fast process.

I want to get this clear:
Every older guest UML kernel will hang on exit on 2.6.9 hosts from now
on, and there's nothing to fix it but to update the guest UML patches?
This is a nasty limitation in general - because it means that on the
update to 2.6.9, every kernel binary needs to be updated - and finding
rock solid versions of kernels + UML patches is not a fast process.

Yes, I perfectly agree with you. However, there are, for 2.6, the security
fixes which are needed.
Well, it is possible that 2.6.10 (or even 2.6.11) will make again old UML
binaries work. I.e., this is my hope, but no code is ready for this, yet.
In fact, Linus always said "binary compatibility is important".
UML was using a strange undocumented, and unwanted interface, but this is not
a good reason for the kernel to break it. I think they did not even notice
that. Also, however, I find that the breakage is a real bug.
The splitout version of the patches is available, and the
uml-hang-on-2.6.9-host.patch is the one to apply. For 2.4, it cannot be
applied separately, though (it requires one of the current incrementals,
which is included in the patchset).
Unfortunately, it does not work on most kernel versions - it can be adapted,
though, and if I find time, I will.

OK. 2.6.9-bb1 is a fine list of patches! The first tests as UML
are OK. At the moment, I saw one small problem only in
uml-refuse-to-run-if-no-tt-mode-in.patch
Use the following patch to fix it:

Yes, the problem was reported and I already was queueing up the fix.
Btw, how can you do so much for UML? Thanks a lot for what you're doing.
Bye
