tracer: in-kernel agent request graph; drop /proc fallback - #16
Merged
Conversation
Attribute gpg-agent/ssh-agent-mediated touches to the real client from inside the kernel: mark client sockets at unix_accept, then on unix_stream_recvmsg record the requesting peer per agent kind (exact, since the key serializes touches). main.go resolves via tracer.AgentClientPID, so the agentpeer /proc UNIX_DIAG scan and its cap_sys_ptrace/cap_dac_read_search are removed. Also pin CGO_ENABLED=0 so the capped (non-dumpable) binary keeps a readable auxv for cilium's kernel-version detection. Classifier/proctree gain shell-arg normalization so resolved trees name the tool, not the interpreter. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
