Brad Fitzpatrick	41e4e02e57	net/{packet,tstun}: send peerapi port in TSMP pongs For discovery when an explicit hostname/IP is known. We'll still also send it via control for finding peers by a list. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	0fb738760f	wgengine: make Tun optional again, default to fake. This makes setup more explicit in prod codepaths, without requiring a bunch of arguments or helpers for tests and userspace mode. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

David Anderson	44d9929208	wgengine: remove Config.TUNName, require caller to create device. Also factors out device creation and associated OS workarounds to net/tun. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	dad10fee9c	Revert "cmd/tailscaled: split package main into main shim + package" This reverts commit `b81bd8025b`. Not needed. See: https://github.com/golang/go/wiki/Modules#how-can-i-track-tool-dependencies-for-a-module	4 years ago
Brad Fitzpatrick	82c4cb765c	cmd/tailscaled: split package main into main shim + package So we can empty import the guts of cmd/tailscaled from another module for go mod tidy reasons. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	27c4dd9a97	Revert "cmd/tailscaled, ipn/{ipnlocal,ipnserver}: let netstack get access to LocalBackend" This reverts commit `2bc518dcb2`. @namansood didn't end up needing it in his `770aa71ffb`.	4 years ago

Brad Fitzpatrick	0d0ec7853c	cmd/tailscaled: don't require root on darwin with --tun=userspace-networking Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	c0cdca6d06	cmd/tailscaled, logtail: share link monitor from wgengine to logtail Part of overall effort to clean up, unify, use link monitoring more, and make Tailscale quieter when all networks are down. This is especially bad on macOS where we can get killed for not being polite it seems. (But we should be polite in any case) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	38dc6fe758	cmd/tailscaled, wgengine: remove --fake, replace with netstack And add a --socks5-server flag.

Brad Fitzpatrick	38629b62fc	cmd/tailscaled: on darwin, fail early if not root with nicer message Don't do it on all platforms, as Linux folk might be playing container + capability games.	4 years ago
Brad Fitzpatrick	d7569863b5	cmd/tailscaled: fix up install-system-daemon on darwin, add uninstall too Tangentially related to #987, #177, #594, #925, #505	4 years ago

Brad Fitzpatrick	6099ecf7f4	cmd/tailscaled: run as a service on Windows Updates #1232	4 years ago
Brad Fitzpatrick	6254efb9ef	cmd/tailscale{,d}: move debug subcommand to tailscaled Work on reducing the size of the tailscale binary, which is currently pulling in most of the same code as tailscaled. Updates #1181	4 years ago
Brad Fitzpatrick	eb47cba435	cmd/tailscaled: don't require --state for --cleanup	4 years ago
Brad Fitzpatrick	5aa5db89d6	cmd/tailscaled, wgengine/netstack: add start of gvisor userspace netstack work Not usefully functional yet (mostly a proof of concept), but getting it submitted for some work @namansood is going to do atop this. Updates #707 Updates #634 Updates #48 Updates #835	4 years ago
Brad Fitzpatrick	57dd247376	cmd/tailscaled, logpolicy, logtail: support log levels Log levels can now be specified with "[v1] " or "[v2] " substrings that are then stripped and filtered at the final logger. This follows our existing "[unexpected]" etc convention and doesn't require a wholesale reworking of our logging at the moment. cmd/tailscaled then gets a new --verbose=N flag to take a log level that controls what gets logged to stderr (and thus systemd, syslog, etc). Logtail is unaffected by --verbose. This commit doesn't add annotations to any existing log prints. That is in the next commit. Updates #924 Updates #282 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	54e6c3a290	version: use OSS repo's version when building. When building with redo, also include the git commit hash from the proprietary repo, so that we have a precise commit that identifies all build info (including Go toolchain version). Add a top-level build script demonstrating to downstream distros how to burn the right information into builds. Adjust `tailscale version` to print commit hashes when available. Fixes #841.

Brad Fitzpatrick	86c271caba	types/logger: move RusagePrefixLog to logger package, disable by default The RusagePrefixLog is rarely useful, hasn't been useful in a long time, is rarely the measurement we need, and is pretty spammy (and syscall-heavy). Disable it by default. We can enable it when we're debugging memory.	4 years ago
Brad Fitzpatrick	8b94a769be	cmd/tailscaled: use the standard flag page instead of getopt Per discussion with @crawshaw. The CLI tool already used std flag anyway. If either of them, it would've made more sense for the CLI to use getopt.	4 years ago
David Anderson	9e26ffecf8	cmd/tailscaled: ignore SIGPIPE. SIGPIPE can be generated when CLIs disconnect from tailscaled. This should not terminate the process. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	d64de1ddf7	Revert "cmd/tailscaled: exit gracefully on SIGPIPE" tailscaled receives a SIGPIPE when CLIs disconnect from it. We shouldn't shut down in that case. This reverts commit `43b271cb26`. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Brad Fitzpatrick	ff8c8db9d3	cmd/tailscaled: log on shutdown signal	4 years ago
Brad Fitzpatrick	4aba86cc03	ipn/ipnserver: make Engine argument a func that tries again for each connection So a backend in server-an-error state (as used by Windows) can try to create a new Engine again each time somebody re-connects, relaunching the GUI app. (The proper fix is actually fixing Windows issues, but this makes things better in the short term) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Dmytro Shynkevych	318751c486	cmd/tailscaled: always flush logs properly Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	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
Dmytro Shynkevych	61abab999e	cmd/tailscaled: graceful shutdown (#534 ) Signed-off-by: Dmytro Shynkevych <dmytro@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>	5 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>	5 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. Signed-off-by: Wendi Yu <wendi.yu@yahoo.ca>	5 years ago
David Anderson	1ac570def7	wgengine/router: split out from wgengine. The router implementations are logically separate, with their own API. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
