Yes, they were both patched.

I felt unhappy recently because UML was working perfectly well and I had
no complaints (except for the absence of skas3 on 2.6.25
hosts). Obviously this was unacceptable.
So I tried out skas4, host+guest (the guest also has your rng patches,
time fixes, and SIGWINCH fixes applied).
The result:

Hi all,
I would like to apply a skas4 patch to a 2.6.16-gentoo-r3 kernel.
I know It's strange what I would like to do, but my situation is that
my host system has a 2.6.24-gentoo-r4 and I have to use a
2.6.16-gentoo-r3 kernel for the guest OS.
What are your suggestions about doing the best thing?
Is this a 32-bit UML on a 64-bit host?

As for the siginfo stuff
Here is the trace, and after is the print that led to the trace:
Locating the top of the address space ... 0xd000

soft - 102400
hard - NONE

Checking syscall emulation patch for ptrace...OK

That doesn't necessarily mean there's no information. zero might mean
the signal came from a process.
Can you strace it?
Also, send me the full siginfo? There might be somet

kill -9 to clean them.

Odd, you're getting SIGSTOPs for some reason, which is consistent with
this bit later:

I put the patch by hand and replaced VCPU_SIGNALL with VCPU_SIGNAL:
if (vcpu_data.event == VCPU_SIGNAL) {
non_fatal("clownix: vcpu returned with signal %d\n",
vcpu_data.siginfo.si_signo);
goto bad;
}
if (vcpu_data.event

Hello,
The skas4 patch was OK for kernel 2.6.25.4, I rebuilt my
host in my usual way (I take the distrib's config from /boot
and do not modify this config).
My host started ok:

Hello,
Can somebody remind me where the last skas4 patch is, I would
