Fetch source and destination addresses with bpf from tcp kprobes, similar to how it is done for openssl lib.
Chunk contains both source address and destination address.
FD is no longer used to obtain addresses.
Instead of going through the socket fd, addresses are obtained in kprobe/tcp_sendmsg on ssl write and kprobe/tcp_recvmsg on ssl read. The tcp kprobes and the openssl uprobes communicate through the id->sslInfo bpf map.
