The simplest test I have is the following for a difference between kernels:
# uname -a
Linux nuc8i7hvk01 4.19.0-5-amd64 #1 SMP Debian 4.19.37-6 (2019-07-18)
x86_64 GNU/Linux
# cat /sys/kernel/debug/tracing/events/syscalls/sys_enter_execve/id
677
# uname -a
Linux nuc8i7hvk01 5.2.0-2-amd64 #1 SMP Debian 5.2.7-1 (2019-08-07)
x86_64 GNU/Linux
# cat /sys/kernel/debug/tracing/events/syscalls/sys_enter_execve/id
Killed
This prevents bpftrace and other bpf helper based applications from loading.
apparmour, selinux, and audit are all turned off.
Is there a new 'enable' flag some where? Or are things done differently
now? Or is this a Debian 'thing'?
Raymond.
