Alban Crequy	d715ccc391	ebpf: handle fd_install events from tcptracer-bpf ... Since https://github.com/weaveworks/tcptracer-bpf/pull/39, tcptracer-bpf can generate "fd_install" events when a process installs a new file descriptor in its fd table. Those events must be requested explicitely on a per-pid basis with tracer.AddFdInstallWatcher(pid). This is useful to know about "accept" events that would otherwise be missed because kretprobes are not triggered for functions that were called before the installation of the kretprobe. This patch find all the processes that are currently blocked on an accept() syscall during the EbpfTracker initialization. feedInitialConnections() will use tracer.AddFdInstallWatcher() to subscribe to fd_install events. When a fd_install event is received, synthesise an accept event with the connection tuple and the network namespace (from /proc).	2017-05-19 14:49:38 +02:00

Peter Bourgon	b585a362ac	Naïve process walker for Darwin ... This fixes the regression where process names weren't appearing for Darwin probes. Makes testing easier. Also, changes the process walker to operate on value types. There's no performance advantage to using reference types for something of this size, and there appeared to be a data race in the Darwin port that caused nodes to gain and lose process names over time. Also, restructures how to enable docker scraping. Default false when run manually, and enabled via --probe.docker true in the scope script.	2015-07-16 12:33:59 +02:00
