Brad Fitzpatrick	a04801e037	ipn/ipnlocal: ignore NetfilterMode pref on Synology ... On clean installs we didn't set use iptables, but during upgrades it looks like we could use old prefs that directed us to go into the iptables paths that might fail on Synology.

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	ceaaa23962	wgengine/wglog: cache strings ... We repeat many peers each time we call SetPeers.

Josh Bleecher Snyder	020e904f4e	internal/deephash: add special handling for netaddr.IPPort ... The acyclic map code interacts badly with netaddr.IPs. One of the netaddr.IP fields is an *intern.Value, and we use a few sentinel values. Those sentinel values make many of the netaddr data structures appear cyclic. One option would be to replace the cycle-detection code with a Floyd-Warshall style algorithm. The downside is that this will take longer to detect cycles, particularly if the cycle is long. This problem is exacerbated by the fact that the acyclic cycle detection code shares a single visited map for the entire data structure, not just the subsection of the data structure localized to the map. Unfortunately, the extra allocations and work (and code) to use per-map visited maps make this option not viable. Instead, continue to special-case netaddr data types. name old time/op new time/op delta Hash-8 22.4µs ± 0% 14.0µs ± 0% -37.59% (p=0.008 n=5+5) HashMapAcyclic-8 23.8µs ± 0% 24.3µs ± 1% +1.75% (p=0.008 n=5+5) name old alloc/op new alloc/op delta Hash-8 2.49kB ± 0% 2.16kB ± 0% ~ (p=0.079 n=4+5) HashMapAcyclic-8 2.53kB ± 0% 2.53kB ± 0% ~ (all equal) name old allocs/op new allocs/op delta Hash-8 86.0 ± 0% 77.0 ± 0% -10.47% (p=0.008 n=5+5) HashMapAcyclic-8 202 ± 0% 202 ± 0% ~ (all equal) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 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

Josh Bleecher Snyder	6f62bbae79	cmd/tailscale: make ping --until-direct require direct connection to exit 0 ... If --until-direct is set, the goal is to make a direct connection. If we failed at that, say so, and exit with an error. RELNOTE=tailscale ping --until-direct (the default) now exits with a non-zero exit code if no direct connection was established.

Avery Pennarun	6fd4e8d244	ipnlocal: fix switching users while logged in + Stopped. ... This code path is very tricky since it was originally designed for the "re-authenticate to refresh my keys" use case, which didn't want to lose the original session even if the refresh cycle failed. This is why it acts differently from the Logout(); Login(); case. Maybe that's too fancy, considering that it probably never quite worked at all, for switching between users without logging out first. But it works now. This was more invasive than I hoped, but the necessary fixes actually removed several other suspicious BUG: lines from state_test.go, so I'm pretty confident this is a significant net improvement.
