grsecurity forums

Hello,

The grsecurity-3.0-3.15.8-201407312007.patch causes "refcount overflows" in ntpdate/ping
and a "size overflow detected" in atomic_add_return in my dmesg output.

The output of those msgs are in the dmesg file listed below. Also included are my kernel, config, and System.map

https://home.comcast.net/~x14sg1/System ... -grsec-smp
https://home.comcast.net/~x14sg1/config ... -grsec-smp
https://home.comcast.net/~x14sg1/vmlinu ... -grsec-smp
https://home.comcast.net/~x14sg1/dmesg

Forgot to mention, I see similar errors on a non-Virtualbox system running the same Kernel/config

in net/ipv4/route.c:ip_idents_reserve() change the atomic_add_return to an atomic_add_return_unchecked and it should work.

Thanks - that fixed it.
