Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups ... On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail). Fixed by passing around a netmon.Monitor to more places, so that we can use its cached interface state. Fixes #7850 Updates #7621 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Will Norris	7f17e04a5a	log/sockstatlog: bump logInterval to 10 seconds ... We are seeing indications that some devices are still getting into an upload loop. Bump logInterval in case these devices are on slow connections that are taking more than 3 seconds to uploads sockstats. Updates #7719 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago

Will Norris	62a1e9a44f	log/sockstatlog: add delay before writing logs to disk ... Split apart polling of sockstats and logging them to disk. Add a 3 second delay before writing logs to disk to prevent an infinite upload loop when uploading stats to logcatcher. Fixes #7719 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago

Will Norris	57a008a1e1	all: pass log IDs as the proper type rather than strings ... This change focuses on the backend log ID, which is the mostly commonly used in the client. Tests which don't seem to make use of the log ID just use the zero value. Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Will Norris	f13b8bf0cf	log: use logtail to log and upload sockstat logs ... Switch to using logtail for logging sockstat logs. Always log locally (on supported platforms), but disable automatic uploading. Change existing c2n sockstats request to trigger upload to log server and return log ID.
