Joe Tsai	a1a43ed266	wgengine/netlog: add support for magicsock statistics (#5913) ... This sets up Logger to handle statistics at the magicsock layer, where we can correlate traffic between a particular tailscale IP address and any number of physical endpoints used to contact the node that hosts that tailscale address. We also export Message and TupleCounts to better document the JSON format that is being sent to the logging infrastructure. This commit does NOT yet enable the actual logging of magicsock statistics. That will be a future commit. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	4 years ago
Joe Tsai	f9120eee57	wgengine: start network logger in Userspace.Reconfig (#5908) ... If the wgcfg.Config is specified with network logging arguments, then Userspace.Reconfig starts up an asynchronous network logger, which is shutdown either upon Userspace.Close or when Userspace.Reconfig is called again without network logging or route arguments.

Joe Tsai	1b4e4cc1e8	wgengine/netlog: new package for traffic flow logging (#5864) ... The Logger type managers a logtail.Logger for extracting statistics from a tstun.Wrapper. So long as Shutdown is called, it ensures that logtail and statistic gathering resources are properly cleared up. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	4 years ago
