2.6.18 patch problems

[linkfanel]

Hello there,

I just tested the last grsecurity-2.1.9-2.6.18-200609222230.patch with my previous .config settings, and it compiles and runs seemingly well, except that I have no log at all on my system! Both klog and syslog don't seem to work, and log files remain empty. Neither do I get grsec-generated logs (such as when time is set) displayed on console after bootup (whereas I get some during bootup). Log system works fine with a not patched 2.6.18 kernel.

So I wanted to try a kernel with no grsec option enabled, but I ran into another problem : kernel fails to compile.

Same problem I'm having.

Hi again,

Using the latest grsecurity-2.1.9-2.6.18-200609251756.patch, it looks like my log system gets broken when I enable CONFIG_PAX_MEMORY_UDEREF (even when only this option).

Moreover, I'm still getting compilation errors with my original .config :

i had the same problem, but with the new patch from date 25-Sep-2006 18:44
Everything is ok, the kernel is now compiling

All problems listed here should be fixed with the latest patch in ~spender.

I'm not sure if it is what you meant, but I confirm that my log system is still broken when I enable CONFIG_PAX_MEMORY_UDEREF

Here is a strace output of syslogd I could produce : http://andrea.via.ecp.fr/syslogd

thanks, i fixed the problem (was something in linux itself that UDEREF exposed), new test patch is up, the interdiff should apply to grsec as well.

[linkfanel]

It is working with the last PaX patch. Thanks!
