Brad Fitzpatrick	1598cd0361	net/tsaddr: remove ContainsFunc helpers (they're now in x/exp/slices) x/exp/slices now has ContainsFunc (golang/go#53983) so we can delete our versions.

Brad Fitzpatrick	e9c851b04b	ipn/ipnlocal: also accept service IP IPv6 literal in brackets for quad100 The fix in `4fc8538e2` was sufficient for IPv6. Browsers (can?) send the IPv6 literal, even without a port number, in brackets.

Maisem Ali	8e85227059	cmd/tailscale/cli: [set] handle selectively modifying routes/exit node Noticed this while debugging something else, we would reset all routes if either `--advertise-exit-node` or `--advertise-routes` were set. This handles correctly updating them. Also added tests. Signed-off-by: Maisem Ali <maisem@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	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.

Brad Fitzpatrick	d413850bd7	cmd/tailscale: add "debug via" subcommand to do CIDR math for via ranges $ tailscale debug via 0xb 10.2.0.0/16 fd7a:115c:a1e0:b1a:0🅱️a02:0/112 $ tailscale debug via fd7a:115c:a1e0:b1a:0🅱️a02:0/112 site 11 (0xb), 10.2.0.0/16 Previously: `3ae701f0eb` This adds a little debug tool to do CIDR math to make converting between those ranges easier for now.

Brad Fitzpatrick	3ae701f0eb	net/tsaddr, wgengine/netstack: add IPv6 range that forwards to site-relative IPv4 This defines a new magic IPv6 prefix, fd7a:115c:a1e0:b1a::/64, a subset of our existing /48, where the final 32 bits are an IPv4 address, and the middle 32 bits are a user-chosen "site ID". (which must currently be 0000:00xx; the top 3 bytes must be zero for now) e.g., I can say my home LAN's "site ID" is "0000:00bb" and then advertise its 10.2.0.0/16 IPv4 range via IPv6, like: tailscale up --advertise-routes=fd7a:115c:a1e0:b1a::bb:10.2.0.0/112 (112 being /128 minuse the /96 v6 prefix length) Then people in my tailnet can: $ curl '[fd7a:115c:a1e0:b1a::bb:10.2.0.230]' <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ....

Brad Fitzpatrick	ca455ac84b	net/tsaddr: simplify TailscaleServiceIP netaddr allocated at the time this was written. No longer. name old time/op new time/op delta TailscaleServiceAddr-4 5.46ns ± 4% 1.83ns ± 3% -66.52% (p=0.008 n=5+5) A bunch of the others can probably be simplified too, but this was the only one with just an IP and not an IPPrefix.

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
