Brad Fitzpatrick	60f4982f9b	cmd/tailscale: move code into new reusable cmd/tailscale/cli package cmd/tailscale's package main is now just a few lines. This'll let us embed the CLI in the Mac and Windows clients. Updates #541	4 years ago
Brad Fitzpatrick	e589c76e98	cmd/tailscaled: don't require --socket path on windows	4 years ago
Brad Fitzpatrick	c1d9e41bef	cmd/tailscaled: use "Tailscale" as default TUN device name on Windows That's what's used in the Windows GUI version and seems special. If we don't use that, Windows tries to rename it and fails.	4 years ago
Brad Fitzpatrick	f98706bdb3	paths, cmd/tailscaled: on Windows, don't try to migrate from legacy relay.conf Avoids confusing logspam on Windows.	4 years ago

Brad Fitzpatrick	0551bec95b	cmd/tailscale: add -active flag to 'tailscale status' to filter out inactive peers	4 years ago
Brad Fitzpatrick	5c6d8e3053	netcheck, tailcfg, interfaces, magicsock: survey UPnP, NAT-PMP, PCP Don't do anything with UPnP, NAT-PMP, PCP yet, but see how common they are in the wild. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	32156330a8	net/interfaces: add func LikelyHomeRouterIP For discovering where we might direct NAT-PMP/PCP/UPnP queries at in the future.	4 years ago
Brad Fitzpatrick	630379a1d0	cmd/tailscale: add tailscale status region name, last write, consistently star There's a lot of confusion around what tailscale status shows, so make it better: show region names, last write time, and put stars around DERP too if active. Now stars are always present if activity, and always somewhere.	4 years ago
Brad Fitzpatrick	3553512a71	cmd/derper: fix embarassing bug introduced in earlier refactor The remove hook implementation was copy/pasted from the line above and I didn't change the body, resulting in packet forwarding routes never being removed. Fortunately we weren't using this path yet, but it led to stats being off, and (very) slow memory growth.	4 years ago
Brian Chu	2a8e064705	cmd/tailscale: Allow advertising subnet routes on *BSD. Use sysctl to check IP forwarding state for better OS compatiblity. Signed-off-by: Brian Chu <cynix@cynix.org>	4 years ago
Brad Fitzpatrick	b87396b5d9	cmd/derper, derp: add some more varz and consistency check handler I'm trying to hunt down a slow drift in numbers not agreeing.	4 years ago
Brad Fitzpatrick	c8cf3169ba	cmd/derper, derp/derphttp: move bulk of derp mesh code into derphttp To be reused in various other tools.	4 years ago
Brad Fitzpatrick	7cbf6ab771	cmd/derper: remove unused parameter in runMeshClient	4 years ago
Brad Fitzpatrick	abd79ea368	derp: reduce DERP memory use; don't require callers to pass in memory to use The magicsock derpReader was holding onto 65KB for each DERP connection forever, just in case. Make the derp{,http}.Client be in charge of memory instead. It can reuse its bufio.Reader buffer space.	4 years ago
Brad Fitzpatrick	1cb7dab881	cmd/derper: support forwarding packets amongst set of peer DERP servers Updates #388 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	5798826990	cmd/derper: add /home/bradfitz/keys to default mesh key search list	4 years ago
Brad Fitzpatrick	484b7fc9a3	derp, cmd/derper: add frameWatchConns, framePeerPresent for inter-DERP routing This lets a trusted DERP client that knows a pre-shared key subscribe to the connection list. Upon subscribing, they get the current set of connected public keys, and then all changes over time. This lets a set of DERP server peers within a region all stay connected to each other and know which clients are connected to which nodes.

David Anderson	c62b80e00b	cmd/tailscale: fix inverted flag meanings. The flags were --no-blah for a brief time, then we switched them to --blah=true/false with a default of true, but didn't fix the boolean inversions in the code. So up was down, true was false, etc. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	83b6b06cc4	cmd/tailscale: fix broken build, result of borked stash pop.	4 years ago
David Anderson	3c7791f6bf	cmd/tailscale: remove double negation arguments. --no-snat becomes --snat-subnet-routes --no-single-routes becomes --host-routes Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	984a699219	cmd/tailscale: warn to stderr that netcheck -format=json isn't stable	4 years ago
Brad Fitzpatrick	0245bbe97b	Make netcheck handle v6-only interfaces better, faster. Also: * add -verbose flag to cmd/tailscale netcheck * remove some API from the interfaces package * convert some of the interfaces package to netaddr.IP * don't even send IPv4 probes on machines with no IPv4 (or only v4 loopback) * and once three regions have replied, stop waiting for other probes at 2x the slowest duration. Updates #376	4 years ago
Brad Fitzpatrick	a96165679c	cmd/tailscale: add netcheck flags for incremental reports, JSON output	4 years ago
Avery Pennarun	9ff51909a3	router_linux: fix behaviour when switching --netfilter-mode. On startup, and when switching into =off and =nodivert, we were deleting netfilter rules even if we weren't the ones that added them. In order to avoid interfering with rules added by the sysadmin, we have to be sure to delete rules only in the case that we added them in the first place. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	85d93fc4e3	cmd/tailscale: make ip_forward warnings more actionable. Let's actually list the file we checked (/proc/sys/net/ipv4/ip_forward). That gives the admin something specific to look for when they get this message. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	99aa33469e	cmd/tailscale: be quiet when no interaction or errors are needed. We would print a message about "nothing more to do", which some people thought was an error or warning. Let's only print a message after authenticating if we previously asked for interaction, and let's shorten that message to just "Success," which is what it means.

Brad Fitzpatrick	b0c10fa610	stun, netcheck: move under net	4 years ago
Brad Fitzpatrick	e6b84f2159	all: make client use server-provided DERP map, add DERP region support Instead of hard-coding the DERP map (except for cmd/tailscale netcheck for now), get it from the control server at runtime. And make the DERP map support multiple nodes per region with clients picking the first one that's available. (The server will balance the order presented to clients for load balancing) This deletes the stunner package, merging it into the netcheck package instead, to minimize all the config hooks that would've been required. Also fix some test flakes & races. Fixes #387 (Don't hard-code the DERP map) Updates #388 (Add DERP region support) Fixes #399 (wgengine: flaky tests) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Avery Pennarun	af9328c1b7	log rate limiting: reformat limiter messages, and use nonempty burst size. - Reformat the warning about a message being rate limited to print the format string, rather than the formatted message. This helps give a clue what "type" of message is being limited. - Change the rate limit warning to be [RATE LIMITED] in all caps. This uses less space on each line, plus is more noticeable. - In tailscaled, change the frequency to be less often (once every 5 seconds per format string) but to allow bursts of up to 5 messages. This greatly reduces the number of messages that are rate limited during startup, but allows us to tighten the limit even further during normal runtime.

Avery Pennarun	f2db4ac277	cmd/tailscaled: SetGCPercent() if GOGC is not set. This cuts RSS from ~30MB to ~20MB on my machine, after the previous fix to get rid of unnecessary zstd buffers. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago

Wendi Yu	bb55694c95	wgengine: log node IDs when peers are added/removed (#381 ) Also stop logging data sent/received from nodes we're not connected to (ie all those `x`s being logged in the `peers: ` line) Signed-off-by: Wendi <wendi.yu@yahoo.ca>	4 years ago

Brad Fitzpatrick	529e2cb31a	ipn: add AllowVersionSkew bool to Notify & Message For "tailscale status" on macOS (from separately downloaded cmd/tailscale binary against App Store IPNExtension). (This isn't all of it, but I've had this sitting around uncommitted.)	4 years ago
Wendi Yu	0c69b4e00d	Implement rate limiting on log messages (#356 ) Implement rate limiting on log messages Addresses issue #317, where logs can get spammed with the same message nonstop. Created a rate limiting closure on logging functions, which limits the number of messages being logged per second based on format string. To keep memory usage as constant as possible, the previous cache purging at periodic time intervals has been replaced by an LRU that discards the oldest string when the capacity of the cache is reached.
