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	7eaf5e509f	net/netaddr: start migrating to net/netip via new netaddr adapter package Updates #5162 Change-Id: Id7bdec303b25471f69d542f8ce43805328d56c12 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Josh Bleecher Snyder	73beaaf360	net/tstun: rate limit "self disco out packet" logging When this happens, it is incredibly noisy in the logs. It accounts for about a third of all remaining "unexpected" log lines from a recent investigation. It's not clear that we know how to fix this, we have a functioning workaround, and we now have a (cheap and efficient) metric for this that we can use for measurements. So reduce the logging to approximately once per minute. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
David Anderson	0532eb30db	all: replace tailcfg.DiscoKey with key.DiscoPublic. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Josh Bleecher Snyder	94fb42d4b2	all: use testingutil.MinAllocsPerRun There are a few remaining uses of testing.AllocsPerRun: Two in which we only log the number of allocations, and one in which dynamically calculate the allocations target based on a different AllocsPerRun run. This also allows us to tighten the "no allocs" test in wgengine/filter. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	080381c79f	net/tstun: block looped disco traffic, take 17 It was in the wrong filter direction before, per CPU profiles we now have. Updates #1526 (maybe fixes? time will tell) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Emmanuel T Odeke	0daa32943e	all: add (*testing.B).ReportAllocs() to every benchmark This ensures that we can properly track and catch allocation slippages that could otherwise have been missed. Fixes #2748	3 years ago
Josh Bleecher Snyder	c2202cc27c	net/tstun: use mono.Time There's a call to Now once per packet. Move to mono.Now. Though the current implementation provides high precision, we document it to be coarse, to preserve the ability to switch to a coarse monotonic time later.

Brad Fitzpatrick	a321c24667	go.mod: update netaddr Involves minor IPSetBuilder.Set API change. Signed-off-by: Brad Fitzpatrick <bradfitz@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
Brad Fitzpatrick	7f2eb1d87a	net/tstun: fix TUN log spam when ACLs drop a packet Whenever we dropped a packet due to ACLs, wireguard-go was logging: Failed to write packet to TUN device: packet dropped by filter Instead, just lie to wireguard-go and pretend everything is okay.
