Brad Fitzpatrick	1cb7dab881	cmd/derper: support forwarding packets amongst set of peer DERP servers Updates #388 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	e441d3218e	tempfork/registry: add golang.org/x/sys/windows/registry + CL 236681 Temporary fork of golang.org/x/sys/windows/registry with: windows/registry: add Key.WaitChange wrapper around RegNotifyChangeKeyValue https://go-review.googlesource.com/c/sys/+/236681	5 years ago
Dmytro Shynkevych	02231e968e	wgengine/tstun: add tests and benchmarks (#436 ) Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	5 years ago
Avery Pennarun	6f590f5b52	logtail: we missed a case for the backoff timer. We want to run bo.Backoff() after every upload, regardless. If upload==true but err!=nil, we weren't backing off, which caused some very-high-throughput log upload retries in bad network conditions. Updates #282.

Brad Fitzpatrick	5e0ff494a5	derp: change NewClient constructor to an option pattern (The NewMeshClient constructor I added recently was gross in retrospect at call sites, especially when it wasn't obvious that a meshKey empty string meant a regular client)	5 years ago
Brad Fitzpatrick	4d599d194f	derp, derp/derphttp: add key accessors, add Client.RecvDetail Client.RecvDetail returns a connection generation so interested clients can detect when a reconnect happened. (Will be needed for #388)	5 years ago
Brad Fitzpatrick	b33c86b542	derp: add an unexported key.Public zero value variable to be less verbose	5 years ago
Brad Fitzpatrick	b663ab4685	cmd/derper: treat self-connection connection watch as no-op Updates #388	5 years ago
Brad Fitzpatrick	5798826990	cmd/derper: add /home/bradfitz/keys to default mesh key search list	5 years ago
David Anderson	e01a4c50ba	go.mod: require Go 1.14, since we use some of its features. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	5a32f8e181	wgengine/router: also accept exit code 254 from `ip rule del`. iproute2 3.16.0-2 from Debian Jessie (oldoldstable) doesn't return exit code 2 when deleting a non-existent IP rule. Fixes #434 Signed-off-by: David Anderson <danderson@tailscale.com>	5 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. Updates #388 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
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>	5 years ago
David Anderson	cc687fc3e6	version: always include the long form version in describe. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	08a38f21c9	wgengine/router: don't filter subnet routing in netfilter. We have a filter in tailscaled itself now, which is more robust against weird network topologies (such as the one Docker creates). Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	c71754eba2	ipn/ipnserver: revert decoder memory limit. The zstd library treats that limit as a hard cap on decompressed size, in the mode we're using it, rather than a window size. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago

Elias Naur	364a8508b2	ipn: add Hostname override to Prefs Overriding the hostname is required for Android, where os.Hostname is often just "localhost". Updates #409 Signed-off-by: Elias Naur <mail@eliasnaur.com>	5 years ago

Brad Fitzpatrick	a5d6c9d616	net/netns: optimize defaultRouteInterface a bit It'll be called a bunch, so worth a bit of effort. Could go further, but not yet.

Brad Fitzpatrick	9e5d79e2f1	wgengine/magicsock: drop a bytes.Buffer sync.Pool, use logger.ArgWriter instead	5 years ago
Brad Fitzpatrick	becce82246	net/netns, misc tests: remove TestOnlySkipPrivilegedOps, argv checks The netns UID check is sufficient for now. We can do something else later if/when needed.	5 years ago
Brad Fitzpatrick	7a410f9236	net/netns: unindent, refactor to remove some redunant code Also: * always error on Control failing. That's very unexpected. * pull out sockopt funcs into their own funcs for easier future testing	5 years ago
Brad Fitzpatrick	45b139d338	net/netns: remove redundant build tag Filename is sufficient.	5 years ago
Brad Fitzpatrick	dcd7a118d3	net/netns: add a test that tailscaleBypassMark stays in sync between packages	5 years ago
Brad Fitzpatrick	1e837b8e81	net/netns: refactor the sync.Once usage a bit	5 years ago
Avery Pennarun	e7ae6a2e06	net/netns, wgengine/router: support Linux machines that don't have 'ip rule'. We'll use SO_BINDTODEVICE instead of fancy policy routing. This has some limitations: for example, we will route all traffic through the interface that has the main "default" (0.0.0.0/0) route, so machines that have multiple physical interfaces might have to go through DERP to get to some peers. But machines with multiple physical interfaces are very likely to have policy routing (ip rule) support anyway. So far, the only OS I know of that needs this feature is ChromeOS (crostini). Fixes #245. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	8575b21ca8	Merge branch 'master' of github.com:tailscale/tailscale * 'master' of github.com:tailscale/tailscale: tailcfg: remove unused, unimplemented DERPNode.CertFingerprint for now net/netns: also don't err on tailscaled -fake as a regular user net/netcheck: fix HTTPS fallback bug from earlier today net/netns: don't return an error if we're not root and running the tailscale binary	5 years ago
Avery Pennarun	e46238a2af	wgengine: separately dedupe wireguard configs and router configs. Otherwise iOS/macOS will reconfigure their routing every time anything minor changes in the netmap (in particular, endpoints and DERP homes), which is way too often. Some users reported "network reconfigured" errors from Chrome when this happens. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	f0b6ba78e8	wgengine: don't pass nil router.Config objects. These are hard for swift to decode in the iOS app. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Brad Fitzpatrick	096d7a50ff	tailcfg: remove unused, unimplemented DERPNode.CertFingerprint for now	5 years ago
Brad Fitzpatrick	765695eaa2	net/netns: also don't err on tailscaled -fake as a regular user That's one of my dev workflows.	5 years ago
Brad Fitzpatrick	7f68e097dd	net/netcheck: fix HTTPS fallback bug from earlier today My earlier `3fa58303d0` tried to implement the net/http.Tranhsport.DialTLSContext hook, but I didn't return a *tls.Conn, so we ended up sending a plaintext HTTP request to an HTTPS port. The response ended up being Go telling as such, not the /derp/latency-check handler's response (which is currently still a 404). But we didn't even get the 404. This happened to work well enough because Go's built-in error response was still a valid HTTP response that we can measure for timing purposes, but it's not a great answer. Notably, it means we wouldn't be able to get a future handler to run server-side and count those latency requests.	5 years ago
Brad Fitzpatrick	1407540b52	net/netns: don't return an error if we're not root and running the tailscale binary tailscale netcheck was broken otherwise. We can fix this a better way later; I'm just fixing a regression in some way because I'm trying to work on netcheck at the moment.	5 years ago
David Anderson	5114df415e	net/netns: set the bypass socket mark on linux. This allows tailscaled's own traffic to bypass Tailscale-managed routes, so that things like tailscale-provided default routes don't break tailscaled itself. Progress on #144.

Brad Fitzpatrick	3fa58303d0	netcheck: address some HTTP fallback measurement TODOs	5 years ago
Brad Fitzpatrick	db2a216561	wgengine/magicsock: don't log on UDP send errors if address family known missing Fixes #376	5 years ago

Brad Fitzpatrick	7247e896b5	net/netcheck: add Report.IPv4 and another TODO	5 years ago
