Brad Fitzpatrick	a2d78b4d3e	net/dnscache, control/controlclient: use DNS cache when dialing control Cache DNS results of earlier login.tailscale.com control dials, and use them for future dials if DNS is slow or broken. Fixes various issues with trickier setups with the domain's DNS server behind a subnet router. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	97e82c6cc0	net/netcheck: remove unused DNSCache from netcheck It's easy to add back later if/when the TODO is implemented.	4 years ago
Brad Fitzpatrick	19b0cfe89e	all: prepare for GOOS=ios in Go 1.16 Work with either way for now on iOS (darwin/arm64 vs ios/arm64). In February when Go 1.16 comes out we'll have a universal binary for darwin/arm64 (macOS) and will drop support for Go 1.15 and its darwin/amd64 meaning iOS. (it'll mean macOS). Context: * https://tip.golang.org/doc/go1.16#darwin * https://github.com/golang/go/issues/38485 * https://github.com/golang/go/issues/42100	4 years ago
Sean Klein	258b680bc5	Patch docker to use valid Go version As documented in the README, tailscale only build with the latest Go version (Go 1.15). As a result, a handful of undefined errors would pop up using an older verison. This patch updates the base image to 1.15, allowing "docker build" to function correctly once more.

Avery Pennarun	b246810377	.gitignore: ignore .tmp files. This fixes the problem where, while running `redo version-info.sh`, the repo would always show up as dirty, because redo creates a temp file named .tmp. This caused the version code to always have a -dirty tag, but not when you run version.sh by hand. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	c03543dbe2	version.sh: keep the short version even if there are patches on top. Instead of reverting to 0.0.0, keep the same version number (eg. 1.2.4) but add an extra suffix with the change count, eg. 1.2.4-6-tb35d95ad7-gcb8be72e6. This avoids the problem where a small patch causes the code to report a totally different version to the server, which might change its behaviour based on version code. (The server might enable various bug workarounds since it thinks 0.0.0 is very old.) Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	0050070493	version.sh: remove use of `git describe --exclude` This option isn't available on slightly older versions of git. We were no longer using the real describe functionality anyway, so let's just do something simpler to detect a dirty worktree. While we're here, fix up a little bit of sh style.

Avery Pennarun	f99f6608ff	Reverse earlier "allow tag without 'tag:' prefix" changes. These accidentally make the tag syntax more flexible than was intended, which will create forward compatibility problems later. Let's go back to the old stricter parser. Revert "cmd/tailscale/cli: fix double tag: prefix in tailscale up" Revert "cmd/tailscale/cli, tailcfg: allow tag without "tag:" prefix in 'tailscale up'" This reverts commit `a702921620`. This reverts commit `cd07437ade`. Affects #861. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago

Brad Fitzpatrick	d21956436a	ipn, tailcfg: change Windows subnet disabling behavior w/ WPAD In 1.0, subnet relays were not specially handled when WPAD+PAC was present on the network. In 1.2, on Windows, subnet relays were disabled if WPAD+PAC was present. That was what some users wanted, but not others. This makes it configurable per domain, reverting back to the 1.0 default state of them not being special. Users who want that behavior can then enable it.

Brad Fitzpatrick	450cfedeba	wgengine/magicsock: quiet an IPv6 warning in tests In tests, we force binding to localhost to avoid OS firewall warning dialogs. But for IPv6, we were trying (and failing) to bind to 127.0.0.1. You'd think we'd just say "localhost", but that's apparently ill defined. See https://tools.ietf.org/html/draft-ietf-dnsop-let-localhost-be-localhost and golang/go#22826. (It's bitten me in the past, but I can't remember specific bugs.) So use "::1" explicitly for "udp6", which makes the test quieter.	4 years ago
chungdaniel	e7ac9a4b90	tsweb: refactor JSONHandler to take status code from error if it is present (#905 ) This change is to make JSONHandler error handling intuitive, as before there would be two sources of HTTP status code when HTTPErrors were generated: one as the first return value of the handler function, and one nested inside the HTTPError. Previously, it took the first return value as the status code, and ignored the code inside the HTTPError. Now, it should expect the first return value to be 0 if there is an error, and it takes the status code of the HTTPError to set as the response code.

Brad Fitzpatrick	07b6ffd55c	ipn: only use Prefs, not computed stateKey, to determine server mode When the service was running without a client (e.g. after a reboot) and then the owner logs in and the GUI attaches, the computed state key changed to "" (driven by frontend prefs), and then it was falling out of server mode, despite the GUI-provided prefs still saying it wanted server mode. Also add some logging. And remove a scary "Access denied" from a user-visible error, making the two possible already-in-use error messages consistent with each other.	4 years ago
