Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Josh Soref	d4811f11a0	all: fix spelling mistakes Signed-off-by: Josh Soref <2119212+jsoref@users.noreply.github.com>	2 years ago
Joe Tsai	e73657d7aa	logpolicy: directly expose the logtail server URL (#5788 ) Callers of LogHost often jump through hoops to undo the loss of information dropped by LogHost (e.g., the HTTP scheme). Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Brad Fitzpatrick	18159431ab	logpolicy: fix, test LogHost to work as documented Change-Id: I225c9602a7587c69c237e336d0714fc8315ea6bd Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Eng Zer Jun	f0347e841f	refactor: move from io/ioutil to io and os packages The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit replaces the existing io/ioutil functions with their new definitions in io and os packages.

Joe Tsai	aa0064db4d	logpolicy: add NewWithConfigPath (#5625 ) The version.CmdName implementation is buggy such that it does not correctly identify the binary name if it embeds other go binaries. For now, add a NewWithConfigPath API that allows the caller to explicitly specify this information. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114.

Denton Gentry	7fd03ad4b4	logpolicy: put QNAP logs buffer in /tmp Ongoing log writing keeps the spinning disks from hibernating. Extends earlier implementation for Synology to also handle QNAP. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	2 years ago
Joe Tsai	fe3426b4c7	logpolicy: fix config initialization bug (#5010 ) If ConfigFromFile cannot find the configuration file, we must not initialize it with NewConfig. Instead, we need it to fail validation so that it eventually writes a newly constructed configuration file. Otherwise, new tailscale instances will never be able store a persistent log config and start with a new config file upon every bootup.

Brad Fitzpatrick	3dedcd1640	logpolicy, ipn/ipnserver: connect to logtail via tailscaled when needed This is for use by the Windows GUI client to log via when an exit node is in use, so the logs don't go out via the exit node and instead go directly, like tailscaled's. The dialer tried to do that in the unprivileged GUI by binding to a specific interface, but the "Internet Kill Switch" installed by tailscaled for exit nodes precludes that from working and instead the GUI fails to dial out. So, go through tailscaled (with a CONNECT request) instead. Fixes tailscale/corp#3169 Change-Id: I17a8efdc1d4b8fed53a29d1c19995592b651b215 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	40e2b312b6	ipn/ipnserver, logpolicy: move Windows disk logging up earlier This moves the Windows-only initialization of the filelogger into logpolicy. Previously we only did it when babysitting the tailscaled subprocess, but this meant that log messages from the service itself never made it to disk. Examples that weren't logged to disk: * logtail unable to dial out, * DNS flush messages from the service * svc.ChangeRequest messages (#3581) This is basically the same fix as #3571 but staying in the Logf type, and avoiding build-tagged file (which wasn't quite a goal, but happened and seemed nice) Fixes #3570 Co-authored-by: Aaron Klotz <aaron@tailscale.com> Change-Id: Iacd80c4720b7218365ec80ae143339d030842702	3 years ago

Brad Fitzpatrick	7d8227e7a6	logpolicy: don't use C:\ProgramData use for tailscale-ipn GUI's log dir tailscale-ipn.exe (the GUI) shouldn't use C:\ProgramData. Also, migrate the earlier misnamed wg32/wg64 conf files if they're present. (That was stopped in `2db877caa3`, but the files exist from fresh 1.14 installs) Updates #2856 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Denton Gentry	280c84e46a	ipn/ipnserver, paths, logpolicy: move Window config files out of %LocalAppData% C:\WINDOWS\system32\config\systemprofile\AppData\Local\ is frequently cleared for almost any reason: Windows updates, System Restore, even various System Cleaner utilities. The server-state.conf file in AppData\Local could be deleted at any time, which would break login until the node is removed from the Admin Panel allowing it to create a new key. Carefully copy any AppData state to ProgramData at startup. If copying the state fails, continue to use AppData so at least there will be connectivity. If there is no state, use ProgramData. We also migrate the log.conf file. Very old versions of Tailscale named the EXE tailscale-ipn, so the log conf was tailscale-ipn.log.conf and more recent versions preserved this filename and cmdName in logs. In this migration we always update the filename to c:\ProgramData\Tailscale\tailscaled.log.conf Updates https://github.com/tailscale/tailscale/issues/2856 Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 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.

Brad Fitzpatrick	6013462e9e	logpolicy: remove inaccurate comment, conditional tryFixLogStateLocation call What I was probably actually hitting was exe caching issues where the binary was updated on a SMB shared drive and I tried to run it with the GUI exe still open, so Windows blends the two pages together and causes all sorts of random corruption. I didn't know about that at the time. Now, just call tryFixLogStateLocation unconditionally. The func itself will bail out early on non-applicable OSes. (And rearrange it to return even a bit earlier.)	4 years ago
David Anderson	9cd4e65191	smallzstd: new package that constructs zstd small encoders/decoders. It's just a config wrapper that passes "use less memory at the expense of compression" parameters by default, so that we don't accidentally construct resource-hungry (de)compressors. Also includes a benchmark that measures the memory cost of the small variants vs. the stock variants. The savings are significant on both compressors (~8x less memory) and decompressors (~1.4x less, not including the savings from the significantly smaller window on the compression side - with those savings included it's more like ~140x smaller).

Brad Fitzpatrick	c3f7733f53	logpolicy: don't check version.CmdName on Windows unnecessarily ... it was crashing for some reason, running out of stack while loading a DLL in goversion. I don't understand Windows (or the Go runtime for Windows) enough to know why that'd be problematic in that context. In any case, don't call it, as tryFixLogStateLocation does nothing on Windows anyway. tryFixLogStateLocation should probably just call version.CmdName itself if/when it needs to, after the GOOS check.	5 years ago
