Hi, I can not run any examples due to this error (I'm using Fedora 33):

The eBPF maps uses locked memory, which is default very low. Your program likely need to increase resource limit RLIMIT_MEMLOCK see system call setrlimit(2).

The bpf_create_map call will return errno EPERM (Operation not permitted) when the RLIMIT_MEMLOCK memory size limit is exceeded.
