Hi,
With a -current from this morning, I have this in my logs:
Sep 28 12:27:37 flynn console-kit-daemon[1113]: WARNING: kvm_openfiles failed:
/dev/mem: Operation not permitted
Sep 28 12:28:30 flynn last message repeated 12 times
It seems that sysutils/consolekit try to play with /dev/mem via kvm(3)
interface, and since the introduction of kern.allowkmem it isn't
possible anymore by default.
Looking at source code, console-kit use only kvm_getenvv(3) function.
As this function is available via kvm(3) for alive kernel (using sysctl
variant), this diff below (untested, sorry) change kvm_openfiles(3) flag
from O_RDONLY to KVM_NO_FILES.
Thanks.
