Brad Fitzpatrick	3984f9be2f	ipn, ipn/ipnserver: add support for serving in error-message-only mode So Windows service failures can be propagated to the Windows UI client.	4 years ago
Brad Fitzpatrick	5280d039c4	version: don't have a third version number form for xcode Our primary version format is git describe --long --abbrev=9. Our Apple scheme is: (major+100).minor.(patch10,000+gitDescribeCommits). This CL gets rid of the third, which was: major.minor.(patch10,000+gitDescribeCommits). Now the "About" box in the macOS app shows the same version that we show on pkgs.tailscale.com, userz, changelog, etc. This will be more important once/if we get standalone DMG downloads for macOS on pkgs.tailscale.com. Fixes tailscale/corp#364	4 years ago
Brad Fitzpatrick	0d481030f3	tailcfg: use ? for portmap summary to match netcheck	4 years ago
Dmytro Shynkevych	67ebba90e1	tsdns: dual resolution mode, IPv6 support (#526 ) This change adds to tsdns the ability to delegate lookups to upstream nameservers. This is crucial for setting Magic DNS as the system resolver. Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Brad Fitzpatrick	ce1b52bb71	wgengine/monitor: fix other potential crashes on Linux Never return "nil, nil" anymore. The caller expected a usable interface now. I missed some of these earlier. Also, handle address deletion now. Updates #532	4 years ago
Brad Fitzpatrick	4b75a27969	wgengine/monitor: fix crash on Linux on type 21 messages Fixes #532	4 years ago
Brad Fitzpatrick	c1cabe75dc	derp: fix server struct fielfd alignment on 32-bit Mostly so the GitHub CI will pass on 32-bit.	4 years ago
Brad Fitzpatrick	724ad13fe1	wgengine/tstun: fix alignment of 64-bit atomic field We had a test for it, but no 32-bit builder apparently. :( Fixes #529	4 years ago
Brad Fitzpatrick	4db60a8436	wgengine/monitor: parse Linux netlink messages, ignore our own events Fixes tailscale/corp#412 ("flood of link change events at start-up") Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	742b8b44a8	net/tsaddr: new package to hold Tailscale-specific IPs/ranges And update existing callers with (near) duplicated cases.	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	6196b7e658	wgengine/magicsock: change API to not permit disco key changes Generate the disco key ourselves and give out the public half instead. Fixes #525	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	c3c607e78a	util/lineread: add little package to read lines from files/Readers	4 years ago
Brad Fitzpatrick	cf74e9039e	net/netcheck: add an informative payload in the netcheck UDP helper packets Per comment from @normanr: `0a5ab533c1 (r40401954)` Updates #188	4 years ago
Brad Fitzpatrick	0a5ab533c1	net/netcheck: send dummy packet out to help airport extreme in hairpin check At least the Apple Airport Extreme doesn't allow hairpin sends from a private socket until it's seen traffic from that src IP:port to something else out on the internet. See https://github.com/tailscale/tailscale/issues/188#issuecomment-600728643 And it seems that even sending to a likely-filtered RFC 5737 documentation-only IPv4 range is enough to set up the mapping. So do that for now. In the future we might want to classify networks that do and don't require this separately. But for now help it. I've confirmed that this is enough to fix the hairpin check on Avery's home network, even using the RFC 5737 IP. Fixes #188	4 years ago
Brad Fitzpatrick	b9a95e6ce1	go.sum: add missing lines	4 years ago
Brad Fitzpatrick	0fc15dcbd5	version: explicitly use 9 hex digits in git describe version number So it doesn't vary based on who's doing the release with which version of git. Fixes tailscale/corp#419	4 years ago
Brad Fitzpatrick	5132edacf7	wgengine/magicsock: fix data race from undocumented wireguard-go requirement Endpoints need to be Stringers apparently. Fixes tailscale/corp#422	4 years ago
Brad Fitzpatrick	9fbe8d7cf2	go.mod: bump wireguard	4 years ago

Brad Fitzpatrick	3f74859bb0	version: new month, new date string	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	0ea51872c9	types/logger: add rateFreePrefix rate-limiting-exempt log format prefixes Per conversation with @danderson.	4 years ago
Brad Fitzpatrick	9a8700b02a	wgengine/magicsock: add discoEndpoint heartbeat Updates #483	4 years ago
Brad Fitzpatrick	9f930ef2bf	wgengine/magicsock: remove the discoEndpoint.timers map It ended up being more complicated than it was worth.	4 years ago
Brad Fitzpatrick	f5f3885b5b	wgengine/magicsock: bunch of misc discovery path cleanups * fix tailscale status for peers using discovery * as part of that, pull out disco address selection into reusable and testable discoEndpoint.addrForSendLocked * truncate ping/pong logged hex txids in half to eliminate noise * move a bunch of random time constants into named constants with docs * track a history of per-endpoint pong replies for future use & status display * add "send" and " got" prefix to discovery message logging immediately before the frame type so it's easier to read than searching for the "<-" or "->" arrows earlier in the line; but keep those as the more reasily machine readable part for later.

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).
