Val	893bdd729c	disco,net/tstun,wgengine/magicsock: probe peer MTU Automatically probe the path MTU to a peer when peer MTU is enabled, but do not use the MTU information for anything yet. Updates #311 Signed-off-by: Val <valerie@tailscale.com>	1 year ago
salman aljammaz	25a7204bb4	wgengine,ipn,cmd/tailscale: add size option to ping (#8739 ) This adds the capability to pad disco ping message payloads to reach a specified size. It also plumbs it through to the tailscale ping -size flag. Disco pings used for actual endpoint discovery do not use this yet. Updates #311.

David Anderson	9a76deb4b0	disco: move disco pcap helper to disco package Updates tailscale/corp#13464 Signed-off-by: David Anderson <danderson@tailscale.com>	1 year ago
Brad Fitzpatrick	b1248442c3	all: update to Go 1.20, use strings.CutPrefix/Suffix instead of our fork Updates #7123 Updates #5309 Change-Id: I90bcd87a2fb85a91834a0dd4be6e03db08438672 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	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
Mihai Parparita	33520920c3	all: use strs.CutPrefix and strs.CutSuffix more Updates places where we use HasPrefix + TrimPrefix to use the combined function. Updates #5309 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Brad Fitzpatrick	da8def8e13	all: remove old +build tags The //go:build syntax was introduced in Go 1.17: https://go.dev/doc/go1.17#build-lines gofmt has kept the +build and go:build lines in sync since then, but enough time has passed. Time to remove them. Done with: perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build') Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Brad Fitzpatrick	8725b14056	all: migrate more code code to net/netip directly Instead of going through the tailscale.com/net/netaddr transitional wrappers. Updates #5162 Change-Id: I3dafd1c2effa1a6caa9b7151ecf6edd1a3fda3dd Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	116f55ff66	all: gofmt for Go 1.19 Updates #5210 Change-Id: Ib02cd5e43d0a8db60c1f09755a8ac7b140b670be Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	a12aad6b47	all: convert more code to use net/netip directly perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.) perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPort,netip.AddrPort,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IP\b,netip.Addr,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. ) goimports -w . Then delete some stuff from the net/netaddr shim package which is no longer neeed.

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.

David Anderson	6422789ea0	disco: use key.NodePublic instead of tailcfg.NodeKey. Updates #3206 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	e7eb46bced	wgengine/magicsock: add an explicit else branch to peerMap update. Clarifies that the replace+delete of peerinfo data is only when peerInfo already exists. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	1c56643136	disco: amplify comment that disco ping's NodeKey shouldn't be trusted by itself. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Brad Fitzpatrick	75a7779b42	disco, wgengine/magicsock: send self node key in disco pings This lets clients quickly (sub-millisecond within a local LAN) map from an ambiguous disco key to a node key without waiting for a CallMeMaybe (over relatively high latency DERP).

Josh Bleecher Snyder	a5da4ed981	all: gofmt with Go 1.17 This adds "//go:build" lines and tidies up existing "// +build" lines. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
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

Brad Fitzpatrick	a6559a8924	wgengine/magicsock: run test DERP in mode where only disco packets allowed So we don't accidentally pass a NAT traversal test by having DERP pick up our slack when we really just wanted DERP as an OOB messaging channel.	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.

Brad Fitzpatrick	77d3ef36f4	wgengine/magicsock: hook up discovery messages, upgrade to LAN works Ping messages now go out somewhat regularly, pong replies are sent, and pong replies are now partially handled enough to upgrade off DERP to LAN. CallMeMaybe packets are sent & received over DERP, but aren't yet handled. That's next (and regular maintenance timers), and then WAN should work. Updates #483	4 years ago
