Anton Tolchanov	5d61d1c7b0	log/sockstatlog: don't block for more than 5s on shutdown Fixes tailscale/corp#21618 Signed-off-by: Anton Tolchanov <anton@tailscale.com>	4 months ago
Brad Fitzpatrick	3672f29a4e	net/netns, net/dns/resolver, etc: make netmon required in most places The goal is to move more network state accessors to netmon.Monitor where they can be cheaper/cached. But first (this change and others) we need to make sure the one netmon.Monitor is plumbed everywhere. Some notable bits: * tsdial.NewDialer is added, taking a now-required netmon * because a tsdial.Dialer always has a netmon, anything taking both a Dialer and a NetMon is now redundant; take only the Dialer and get the NetMon from that if/when needed. * netmon.NewStatic is added, primarily for tests Updates tailscale/corp#10910 Updates tailscale/corp#18960 Updates #7967 Updates #3299 Change-Id: I877f9cb87618c4eb037cee098241d18da9c01691 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	7 months ago
Brad Fitzpatrick	745931415c	health, all: remove health.Global, finish plumbing health.Tracker Updates #11874 Updates #4136 Change-Id: I414470f71d90be9889d44c3afd53956d9f26cd61 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	7 months ago
Joe Tsai	85febda86d	all: use zstdframe where sensible (#11491 ) Use the zstdframe package where sensible instead of plumbing around our own zstd.Encoder just for stateless operations. This causes logtail to have a dependency on zstd, but that's arguably okay since zstd support is implicit to the protocol between a client and the logging service. Also, virtually every caller to logger.NewLogger was manually setting up a zstd.Encoder anyways, meaning that zstd was functionally always a dependency.

Andrew Dunham	60ab8089ff	logpolicy, various: allow overriding log function This allows sending logs from the "logpolicy" package (and associated callees) to something other than the log package. The behaviour for tailscaled remains the same, passing in log.Printf Updates #8249 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: Ie1d43b75fa7281933d9225bffd388462c08a5f31	1 year ago
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.
