David Anderson	86fe22a1b1	Update netaddr, and adjust wgengine/magicsock due to API change. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Josh Bleecher Snyder	56a7652dc9	wgkey: new package This is a replacement for the key-related parts of the wireguard-go wgcfg package. This is almost a straight copy/paste from the wgcfg package. I have slightly changed some of the exported functions and types to avoid stutter, added and tweaked some comments, and removed some now-unused code. To avoid having wireguard-go depend on this new package, wgcfg will keep its key types. We translate into and out of those types at the last minute. These few remaining uses will be eliminated alongside the rest of the wgcfg package. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

David Anderson	cb96b14bf4	net/packet: remove the custom IP4/IP6 types in favor of netaddr.IP. Upstream netaddr has a change that makes it alloc-free, so it's safe to use in hot codepaths. This gets rid of one of the many IP types in our codebase. Performance is currently worse across the board. This is likely due in part to netaddr.IP being a larger value type (4b -> 24b for IPv4, 16b -> 24b for IPv6), and in other part due to missing low-hanging fruit optimizations in netaddr. However, the regression is less bad than it looks at first glance, because we'd micro-optimized packet.IP* in the past few weeks. This change drops us back to roughly where we were at the 1.2 release, but with the benefit of a significant code and architectural simplification. name old time/op new time/op delta pkg:tailscale.com/net/packet goos:linux goarch:amd64 Decode/tcp4-8 12.2ns ± 5% 29.7ns ± 2% +142.32% (p=0.008 n=5+5) Decode/tcp6-8 12.6ns ± 3% 65.1ns ± 2% +418.47% (p=0.008 n=5+5) Decode/udp4-8 11.8ns ± 3% 30.5ns ± 2% +157.94% (p=0.008 n=5+5) Decode/udp6-8 27.1ns ± 1% 65.7ns ± 2% +142.36% (p=0.016 n=4+5) Decode/icmp4-8 24.6ns ± 2% 30.5ns ± 2% +23.65% (p=0.016 n=4+5) Decode/icmp6-8 22.9ns ±51% 65.5ns ± 2% +186.19% (p=0.008 n=5+5) Decode/igmp-8 18.1ns ±44% 30.2ns ± 1% +66.89% (p=0.008 n=5+5) Decode/unknown-8 20.8ns ± 1% 10.6ns ± 9% -49.11% (p=0.016 n=4+5) pkg:tailscale.com/wgengine/filter goos:linux goarch:amd64 Filter/icmp4-8 30.5ns ± 1% 77.9ns ± 3% +155.01% (p=0.008 n=5+5) Filter/tcp4_syn_in-8 43.7ns ± 3% 123.0ns ± 3% +181.72% (p=0.008 n=5+5) Filter/tcp4_syn_out-8 24.5ns ± 2% 45.7ns ± 6% +86.22% (p=0.008 n=5+5) Filter/udp4_in-8 64.8ns ± 1% 210.0ns ± 2% +223.87% (p=0.008 n=5+5) Filter/udp4_out-8 119ns ± 0% 278ns ± 0% +133.78% (p=0.016 n=4+5) Filter/icmp6-8 40.3ns ± 2% 204.4ns ± 4% +407.70% (p=0.008 n=5+5) Filter/tcp6_syn_in-8 35.3ns ± 3% 199.2ns ± 2% +464.95% (p=0.008 n=5+5) Filter/tcp6_syn_out-8 32.8ns ± 2% 81.0ns ± 2% +147.10% (p=0.008 n=5+5) Filter/udp6_in-8 106ns ± 2% 290ns ± 2% +174.48% (p=0.008 n=5+5) Filter/udp6_out-8 184ns ± 2% 314ns ± 3% +70.43% (p=0.016 n=4+5) pkg:tailscale.com/wgengine/tstun goos:linux goarch:amd64 Write-8 9.02ns ± 3% 8.92ns ± 1% ~ (p=0.421 n=5+5) name old alloc/op new alloc/op delta pkg:tailscale.com/net/packet goos:linux goarch:amd64 Decode/tcp4-8 0.00B 0.00B ~ (all equal) Decode/tcp6-8 0.00B 0.00B ~ (all equal) Decode/udp4-8 0.00B 0.00B ~ (all equal) Decode/udp6-8 0.00B 0.00B ~ (all equal) Decode/icmp4-8 0.00B 0.00B ~ (all equal) Decode/icmp6-8 0.00B 0.00B ~ (all equal) Decode/igmp-8 0.00B 0.00B ~ (all equal) Decode/unknown-8 0.00B 0.00B ~ (all equal) pkg:tailscale.com/wgengine/filter goos:linux goarch:amd64 Filter/icmp4-8 0.00B 0.00B ~ (all equal) Filter/tcp4_syn_in-8 0.00B 0.00B ~ (all equal) Filter/tcp4_syn_out-8 0.00B 0.00B ~ (all equal) Filter/udp4_in-8 0.00B 0.00B ~ (all equal) Filter/udp4_out-8 16.0B ± 0% 64.0B ± 0% +300.00% (p=0.008 n=5+5) Filter/icmp6-8 0.00B 0.00B ~ (all equal) Filter/tcp6_syn_in-8 0.00B 0.00B ~ (all equal) Filter/tcp6_syn_out-8 0.00B 0.00B ~ (all equal) Filter/udp6_in-8 0.00B 0.00B ~ (all equal) Filter/udp6_out-8 48.0B ± 0% 64.0B ± 0% +33.33% (p=0.008 n=5+5) name old allocs/op new allocs/op delta pkg:tailscale.com/net/packet goos:linux goarch:amd64 Decode/tcp4-8 0.00 0.00 ~ (all equal) Decode/tcp6-8 0.00 0.00 ~ (all equal) Decode/udp4-8 0.00 0.00 ~ (all equal) Decode/udp6-8 0.00 0.00 ~ (all equal) Decode/icmp4-8 0.00 0.00 ~ (all equal) Decode/icmp6-8 0.00 0.00 ~ (all equal) Decode/igmp-8 0.00 0.00 ~ (all equal) Decode/unknown-8 0.00 0.00 ~ (all equal) pkg:tailscale.com/wgengine/filter goos:linux goarch:amd64 Filter/icmp4-8 0.00 0.00 ~ (all equal) Filter/tcp4_syn_in-8 0.00 0.00 ~ (all equal) Filter/tcp4_syn_out-8 0.00 0.00 ~ (all equal) Filter/udp4_in-8 0.00 0.00 ~ (all equal) Filter/udp4_out-8 1.00 ± 0% 1.00 ± 0% ~ (all equal) Filter/icmp6-8 0.00 0.00 ~ (all equal) Filter/tcp6_syn_in-8 0.00 0.00 ~ (all equal) Filter/tcp6_syn_out-8 0.00 0.00 ~ (all equal) Filter/udp6_in-8 0.00 0.00 ~ (all equal) Filter/udp6_out-8 1.00 ± 0% 1.00 ± 0% ~ (all equal) Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

David Crawshaw	2b2a16d9a2	wgengine/router/dns: reduce windows registry key open timeout The windows key timeout is longer than the wgengine watchdog timeout, which means we never reach the timeout, instead the process exits.

David Crawshaw	b4f70d8232	wgengine/router/dns: use the correct interface GUID On Win10, there's a hardcoded GUID and this works. On Win7, this GUID changes and we need to ask the tun for its LUID and convert that from the GUID. This commit uses the computed GUID that is placed in InterfaceName. Diagnosed by Jason Donnenfeld.

Brad Fitzpatrick	57dd247376	cmd/tailscaled, logpolicy, logtail: support log levels Log levels can now be specified with "[v1] " or "[v2] " substrings that are then stripped and filtered at the final logger. This follows our existing "[unexpected]" etc convention and doesn't require a wholesale reworking of our logging at the moment. cmd/tailscaled then gets a new --verbose=N flag to take a log level that controls what gets logged to stderr (and thus systemd, syslog, etc). Logtail is unaffected by --verbose. This commit doesn't add annotations to any existing log prints. That is in the next commit.

David Anderson	baa7937998	net/interfaces: return IPv6 addresses from LocalAddresses. In practice, we already provide IPv6 endpoint addresses via netcheck, and that address is likely to match a local address anyway (i.e. no NAT66). The comment at that piece of the code mentions needing to figure out a good priority ordering, but that only applies to non-active-discovery clients, who already don't do anything with IPv6 addresses.

David Anderson	891110e64c	wgengine: expand lazy config to work with dual-stacked peers. Lazy wg configuration now triggers if a peer has only endpoint addresses (/32 for IPv4, /128 for IPv6).

Smitty	f0b0a62873	Clarify that raw format strings are intentional This caused some confusion in issue #460, since usually raw format strings aren't printed directly. Hopefully by directly logging that they are intended to be raw format strings, this will be more clear. Rate limited format strings now look like: [RATE LIMITED] format string "control: sendStatus: %s: %v" Closes #460. Signed-off-by: Smitty <me@smitop.com>	4 years ago
David Anderson	c8c493f3d9	wgengine/magicsock: make ReceiveIPv4 a little easier to follow.

David Anderson	554a20becb	wgengine/magicsock: only log about lazy config when actually doing lazy config. Before, tailscaled would log every 10 seconds when the periodic noteRecvActivity call happens. This is noisy, but worse it's misleading, because the message suggests that the disco code is starting a lazy config run for a missing peer, whereas in fact it's just an internal piece of keepalive logic. With this change, we still log when going from 0->1 tunnel for the peer, but not every 10s thereafter. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
