grsecurity forums

Hi,

when trying to compile my own kernel on a system where a grsecurity patched kernel is running with the option CONFIG_PAX_MEMORY_UDEREF set to Yes the compilation fails. The reason is that the file include/generated/utsrelease.h is not properly generated and this is perfectly reproducible. The fastest way to check is to just call

make prepare

and then

cat include/generated/utsrelease.h

will print:

CHK include/generated/utsrelease

Of course, this file cannot be successfully compiled anymore. As soon as I disable CONFIG_PAX_MEMORY_UDEREF "make prepare" updates the utsrelease.h properly again.

Is this a kernel bug or a grsecurity bug?

Thanks, Michael

what's the exact kernel and grsec version? do you get any reports from PaX in dmesg (if UDEREF actually triggers then you should see something)?

Versions: grsecurity-2.2.2-2.6.39.2-201106251302.patch on 2.6.39.2
uname -a: Linux host 2.6.39.2-grsec+ #1 SMP PREEMPT Wed Jun 29 20:18:54 CEST 2011 x86_64 GNU/Linux

It did happen with earlier kernel versions as well but back then I had no idea what was going on. And no, dmesg shows no UDEREF or PaX messages, I have just verified it. If it is of any value I can post my .config file. Also, I have disabled all other grsec options and only enabled this one PaX option from the grsecurity patch to be sure it is just that option which causes the problem. I am running Debian unstable.

do you perhaps remember when things started to fail? my guess is that it's probably the per-cpu PGD stuff again that got introduced with UDEREF/amd64 over a year ago (KERNEXEC also enables it, does that affect the results for you?).

If it is of any value I can post my .config file.

yes, that may be useful, especially if i can then reproduce the problem here otherwise i'll need your help to debug it. what's your CPU btw (/proc/cpuinfo)?

Sorry for the delay, been offline for a while. No, I don't know exactly when this started happening because I was switching kernels and didn't notice that this was related to this problem. I think it was somewhen in March/April, it's just a guess though. How can I attach a file in this forum? I seem to overlook it?!
