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.

Maisem Ali	50b4b8b2c6	ipn/ipnlocal: make peerIPs return a sorted slice Currently peerIPs doesn't do any sorting of the routes it returns. This is typically fine, however imagine the case of an HA subnet router failover. When a route R moves from peer A to peer B, the output of peerIPs changes. This in turn causes all the deephash check inside wgengine to fail as the hashed value of [R1, R2] is different than the hashed value of [R2, R1]. When the hash check failes, it causes wgengine to reconfigure all routes in the OS. This is especially problematic for macOS and iOS where we use the NetworkExtension. This commit makes it that the peerIPs are always sorted when returned, thus making the hash be consistent as long as the list of routes remains static.

Josh Bleecher Snyder	add6dc8ccc	ipn/ipnlocal: make TestShrinkDefaultRoute hermetic Make shrinkDefaultRoute a pure function. Instead of calling interfaceRoutes, accept that information as parameters.

Brad Fitzpatrick	486059589b	all: gofmt -w -s (simplify) tests And it updates the build tag style on a couple files. Change-Id: I84478d822c8de3f84b56fa1176c99d2ea5083237 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	c37af58ea4	net/tsdial: move more weirdo dialing into new tsdial package, plumb Not done yet, but this move more of the outbound dial special casing from random packages into tsdial, which aspires to be the one unified place for all outbound dialing shenanigans. Then this plumbs it all around, so everybody is ultimately holding on to the same dialer. As of this commit, macOS/iOS using an exit node should be able to reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt to stay within the Network Extension. A number of steps remain, including but limited to: * move a bunch more random dialing stuff * make netstack-mode tailscaled be able to use exit node's DNS proxy, teaching tsdial's resolver to use it when an exit node is in use.

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
Avery Pennarun	b7e31ab1a4	ipn: mock controlclient.Client; big ipn.Backend state machine test. A very long unit test that verifies the way the controlclient and ipn.Backend interact. This is a giant sequential test of the state machine. The test passes, but only because it's asserting all the wrong behaviour. I marked all the behaviour I think is wrong with BUG comments, and several additional test opportunities with TODO. Note: the new test supercedes TestStartsInNeedsLoginState, which was checking for incorrect behaviour (although the new test still checks for the same incorrect behaviour) and assumed .Start() would converge before returning, which it happens to do, but only for this very specific case, for the current implementation. You're supposed to wait for the notifications. Updates: tailscale/corp#1660 Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
