Research direction
Start by reproducing the reported SSH connection with the tcpaccept-bpfcc entry point on Ubuntu 18.04 and kernel 4.15.0-43-generic. Check whether accepted TCP connections appear in the tool output; done means identifying the cause of the missing event or documenting the confirmed compatibility limitation.
