Brad Fitzpatrick	f3c96df162	ipn/ipnstate: move tailscale status "active" determination to tailscaled Fixes #2579 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Josh Bleecher Snyder	8a3d52e882	wgengine/magicsock: use mono.Time magicsock makes multiple calls to Now per packet. Move to mono.Now. Changing some of the calls to use package mono has a cascading effect, causing non-per-packet call sites to also switch. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.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>	3 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>	3 years ago
Josh Bleecher Snyder	a0dacba877	wgengine/magicsock: simplify legacy endpoint DstToString Legacy endpoints (addrSet) currently reconstruct their dst string when requested. Instead, store the dst string we were given to begin with. In addition to being simpler and cheaper, this makes less code aware of how to interpret endpoint strings.

Josh Bleecher Snyder	7ee891f5fd	all: delete wgcfg.Key and wgcfg.PrivateKey For historical reasons, we ended up with two near-duplicate copies of curve25519 key types, one in the wireguard-go module (wgcfg) and one in the tailscale module (types/wgkey). Then we moved wgcfg to the tailscale module. We can now remove the wgcfg key type in favor of wgkey. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	3 years ago
Brad Fitzpatrick	c19ed37b0f	wgengine/magicsock: mark some legacy debug log output as verbose Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Josh Bleecher Snyder	0c673c1344	wgengine/magicsock: unify on netaddr types in addrSet addrSet maintained duplicate lists of netaddr.IPPorts and net.UDPAddrs. Unify to use the netaddr type only. This makes (*Conn).ReceiveIPvN a bit uglier, but that'll be cleaned up in a subsequent commit. This is preparatory work to remove an allocation from ReceiveIPv4.

Josh Bleecher Snyder	dd10babaed	wgenginer/magicsock: remove Addrs methods They are now unused. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	fe7c3e9c17	all: move wgcfg from wireguard-go This is mostly code movement from the wireguard-go repo. Most of the new wgcfg package corresponds to the wireguard-go wgcfg package. wgengine/wgcfg/device{_test}.go was device/config{_test}.go. There were substantive but simple changes to device_test.go to remove internal package device references. The API of device.Config (now wgcfg.DeviceConfig) grew an error return; we previously logged the error and threw it away. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	d3dd7c6270	wgengine/magicsock: make legacy DstToString match Addrs DstToString is used in two places in wireguard-go: Logging and uapi. We are switching to use uapi for wireguard-go config. To preserve existing behavior, we need the full set of addrs. And for logging, having the full set of addrs seems useful. (The Addrs method itself is slated for removal. When that happens, the implementation will move to DstToString.) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	63af950d8c	wgengine/magicsock: adapt to wireguard-go without UpdateDst `22507adf54` stopped relying on our fork of wireguard-go's UpdateDst callback. As a result, we can unwind that code, and the extra return value of ReceiveIPv{4,6}. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
David Anderson	a2463e8948	wgengine/magicsock: add an option to disable legacy peer handling. Used in tests to ensure we're not relying on behavior we're going to remove eventually. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Josh Bleecher Snyder	654b5f1570	all: convert from []wgcfg.Endpoint to string This eliminates a dependency on wgcfg.Endpoint, as part of the effort to eliminate our wireguard-go fork. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
David Anderson	9abcb18061	wgengine/magicsock: import more of wireguard-go, update docstrings. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	22507adf54	wgengine/magicsock: stop depending on UpdateDst in legacy codepaths. This makes connectivity between ancient and new tailscale nodes slightly worse in some cases, but only in cases where the ancient version would likely have failed to get connectivity anyway.

Josh Bleecher Snyder	56a7652dc9	wgkey: new package This is a replacement for the key-related parts of the wireguard-go wgcfg package. This is almost a straight copy/paste from the wgcfg package. I have slightly changed some of the exported functions and types to avoid stutter, added and tweaked some comments, and removed some now-unused code. To avoid having wireguard-go depend on this new package, wgcfg will keep its key types. We translate into and out of those types at the last minute. These few remaining uses will be eliminated alongside the rest of the wgcfg package. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
