failing to load modules after upgrade from 3.16.5 -> 3.17.1
Posted: Tue Oct 21, 2014 10:30 amI used to run linux kernel 3.16.5 (grsec 201410132000) without any problems in a Xen PV guest.
Since grsec moved on to 3.17.x I upgraded to
grsecurity-3.0-3.17.1-201410192051.patch
but I'm having problems with it.
The guest boots up fine but I'm failing to load almost all kernel modules that are usually loaded.
I've not seen any unusual grsec syslog entries.
Trying to load an arbitrary module using modprobe does not result in any warning but the module doesn't load and dmesg output stays untouched (same with the '-v' switch).
Did anything regarding module loading change in 3.17.1-grsec
that requires a specific kernel config change on my side?
How could I collect more info for further debugging?
thanks!
