Maisem Ali	64bbf1738e	tailcfg: make SelfNodeV4MasqAddrForThisPeer a pointer This makes `omitempty` actually work, and saves bytes in each map response. Updates tailscale/corp#8020 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Charlotte Brandhorst-Satzkorn	c573bef0aa	tailcfg,wgengine: add initial support for WireGuard only peers A peer can have IsWireGuardOnly, which means it will not support DERP or Disco, and it must have Endpoints filled in order to be usable. In the present implementation only the first Endpoint will be used as the bestAddr.

Maisem Ali	985535aebc	net/tstun,wgengine/*: add support for NAT to routes This adds support to make exit nodes and subnet routers work when in scenarios where NAT is required. It also updates the NATConfig to be generated from a `wgcfg.Config` as that handles merging prefs with the netmap, so it has the required information about whether an exit node is already configured and whether routes are accepted.

Joe Tsai	0d19f5d421	all: replace logtail.{Public,Private}ID with logid.{Public,Private}ID (#7404 ) The log ID types were moved to a separate package so that code that only depend on log ID types do not need to link in the logic for the logtail client itself. Not all code need the logtail client. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
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
Brad Fitzpatrick	aad6830df0	util/codegen, all: use latest year, not time.Now, in generated files Updates #6865 Change-Id: I6b86c646968ebbd4553cf37df5e5612fbf5c5f7d Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Jordan Whited	ea5ee6f87c	all: update golang.zx2c4.com/wireguard to github.com/tailscale/wireguard-go (#6692 ) This is temporary while we work to upstream performance work in https://github.com/WireGuard/wireguard-go/pull/64. A replace directive is less ideal as it breaks dependent code without duplication of the directive. Signed-off-by: Jordan Whited <jordan@tailscale.com>	2 years ago
Jordan Whited	76389d8baf	net/tstun, wgengine/magicsock: enable vectorized I/O on Linux (#6663 ) This commit updates the wireguard-go dependency and implements the necessary changes to the tun.Device and conn.Bind implementations to support passing vectors of packets in tailscaled. This significantly improves throughput performance on Linux.

Joe Tsai	35c10373b5	types/logid: move logtail ID types here (#6336 ) Many packages reference the logtail ID types, but unfortunately pull in the transitive dependencies of logtail. Fix this problem by putting the log ID types in its own package with minimal dependencies. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	a3602c28bd	wgengine/netlog: embed the StableNodeID of the authoring node (#6105 ) This allows network messages to be annotated with which node it came from. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	82f5f438e0	wgengine/wgcfg: plumb down audit log IDs (#5855 ) The node and domain audit log IDs are provided in the map response, but are ultimately going to be used in wgengine since that's the layer that manages the tstun.Wrapper. Do the plumbing work to get this field passed down the stack. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Andrew Dunham	d6c3588ed3	wgengine/wgcfg: only write peer headers if necessary (#5449 ) On sufficiently large tailnets, even writing the peer header (~95 bytes) can result in a large amount of data that needs to be serialized and deserialized. Only write headers for peers that need to have their configuration changed. Signed-off-by: Andrew Dunham <andrew@tailscale.com>	2 years ago

Brad Fitzpatrick	6a396731eb	all: use various net/netip parse funcs directly Mechanical change with perl+goimports. Changed {Must,}Parse{IP,IPPrefix,IPPort} to their netip variants, then goimports -d . Finally, removed the net/netaddr wrappers, to prevent future use.

Josh Bleecher Snyder	85184a58ed	wgengine/wgcfg: recover from mismatched PublicKey/Endpoints In rare circumstances (tailscale/corp#3016), the PublicKey and Endpoints can diverge. This by itself doesn't cause any harm, but our early exit in response did, because it prevented us from recovering from it. Remove the early exit.

Josh Bleecher Snyder	c467ed0b62	wgengine/wgcfg: always close io.Pipe In DeviceConfig, we did not close r after calling FromUAPI. If FromUAPI returned early due to an error, then it might not have read all the data that IpcGetOperation wanted to write. As a result, IpcGetOperation could hang, as in #3220. We were also closing the wrong end of the pipe after IpcSetOperation in ReconfigDevice. To ensure that we get all available information to diagnose such a situation, include all errors anytime something goes wrong. This should fix the immediate crashing problem in #3220. We'll then need to figure out why IpcGetOperation was failing. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Joe Tsai	9af27ba829	cmd/cloner: mangle "go:generate" in cloner.go The "go generate" command blindly looks for "//go:generate" anywhere in the file regardless of whether it is truly a comment.

David Anderson	daf54d1253	control/controlclient: remove TS_DEBUG_USE_DISCO=only. It was useful early in development when disco clients were the exception and tailscale logs were noisier than today, but now non-disco is the exception.

David Anderson	97693f2e42	wgengine/magicsock: delete legacy AddrSet endpoints. Instead of using the legacy codepath, teach discoEndpoint to handle peers that have a home DERP, but no disco key.

julianknodt	fb06ad19e7	wgcfg: Switch to using mem.RO As Brad suggested, mem.RO allows for a lot of easy perf gains.

julianknodt	664edbe566	wgcfg: add benchmark for FromUAPI Adds a benchmark for FromUAPI in wgcfg. It appears that it's not actually that slow, the main allocations are from the scanner and new config. Updates #1912. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
Josh Bleecher Snyder	1ece91cede	go.mod: upgrade wireguard-windows, de-fork wireguard-go Pull in the latest version of wireguard-windows. Switch to upstream wireguard-go. This requires reverting all of our import paths. Unfortunately, this has to happen at the same time. The wireguard-go change is very low risk, as that commit matches our fork almost exactly. (The only changes are import paths, CI files, and a go.mod entry.) So if there are issues as a result of this commit, the first place to look is wireguard-windows changes.

Josh Bleecher Snyder	25df067dd0	all: adapt to opaque netaddr types This commit is a mishmash of automated edits using gofmt: gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w . gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w . gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w . gofmt -r 'a.IP.As16 -> a.IP().As16' -w . gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w . gofmt -r 'a.IP.As4 -> a.IP().As4' -w . gofmt -r 'a.IP.String -> a.IP().String' -w . And regexps: \w(.)\.Port = (.) -> $1 = $1.WithPort($2) \w(.)\.IP = (.) -> $1 = $1.WithIP($2) And lots of manual fixups. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	aacb2107ae	all: add extra information to serialized endpoints magicsock.Conn.ParseEndpoint requires a peer's public key, disco key, and legacy ip/ports in order to do its job. We currently accomplish that by: * adding the public key in our wireguard-go fork * encoding the disco key as magic hostname * using a bespoke comma-separated encoding It's a bit messy. Instead, switch to something simpler: use a json-encoded struct containing exactly the information we need, in the form we use it. Our wireguard-go fork still adds the public key to the address when it passes it to ParseEndpoint, but now the code compensating for that is just a couple of simple, well-commented lines. Once this commit is in, we can remove that part of the fork and remove the compensating code. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	4 years ago
Josh Bleecher Snyder	bc68e22c5b	all: s/CreateEndpoint/ParseEndpoint/ in docs Upstream wireguard-go renamed the interface method from CreateEndpoint to ParseEndpoint. I missed some comments. Fix them. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	9bce1b7fc1	wgengine/wgcfg: make device test endpoint-format-agnostic By using conn.NewDefaultBind, this test requires that our endpoints be comprehensible to wireguard-go.
