Package: bpftrace
Version: 0.9.2-1+b2
Severity: normal
Dear Maintainer,
I'm trying simple oneliner with bpftrace given in the man pages. For example
following
bpftrace -e 'tracepoint:syscalls:sys_enter_execve { join(args->argv); }'
It fails with following error message
Error creating map: 'join': Invalid argument
Error creating printf map: Invalid argument
Creation of the required BPF maps has failed.
Make sure you have all the required permissions and are not confined (e.g. like
snapcraft does). `dmesg` will likely have useful output for further
troubleshooting
But dmesg does not have any relevant messages. Even running sample tools
shipped with bpftrace
program like execsnoop.bt gives same above message.
I'm unsure if this is package issue or some issue in my system. I'm using
standard Debian unstable
with default Debian kernel. Please let me know if this is something wrong from
myside.
Cheers,
