Brad Fitzpatrick	f9659323df	wgengine/router/dns: fix typo in comment	4 years ago
Brad Fitzpatrick	053a1d1340	all: annotate log verbosity levels on most egregiously spammy log prints Fixes #924 Fixes #282 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	294ceb513c	ipn, wgengine/magicsock: fix `tailscale status` display. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
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). Subnet routers still trigger eager configuration to avoid the need for a CIDR match in the hot packet path. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	c8c493f3d9	wgengine/magicsock: make ReceiveIPv4 a little easier to follow. The previous code used a lot of whole-function variables and shared behavior that only triggered based on prior action from a single codepath. Instead of that, move the small amounts of "shared" code into each switch case. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Brad Fitzpatrick	741c513e51	wgengine/tsdns: fix error response marshaling, improve bad query logs Updates #995 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
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
Brad Fitzpatrick	fa412c8760	wgengine/filter, wgengine/magicsock: use new IP.BitLen to simplify some code	4 years ago

David Anderson	9cee0bfa8c	wgengine/magicsock: sprinkle more docstrings. Magicsock is too damn big, but this might help me page it back in faster next time. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Brad Fitzpatrick	7b92f8e718	wgengine/magicsock: add start of magicsock benchmarks (Conn.ReceiveIPv4 for now) And only single-threaded for now. Will get fancier later. Updates #414	4 years ago

Brad Fitzpatrick	eccc167733	wgengine/monitor: fix memory corruption in Windows implementation I used the Windows APIs wrong previously, but it had worked just enough. Updates #921 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	d9e2edb5ae	wgengine: reconfigure wireguard peer in two steps when its disco key changes First remove the device (to clear its wireguard session key), and then add it back. Fixes #929 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	3c508a58cc	wgengine/filter: don't filter GCP DNS. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	fc8bc76e58	wgengine/router: lock goroutine to OS thread before using OLE [windows] See https://github.com/tailscale/tailscale/issues/921#issuecomment-727526807 Not yet sure whether this is our problem, but it can't hurt at least, and seems like what we're supposed to do. Updates #921	4 years ago
David Anderson	2eb474dd8d	wgengine/filter: add test cases for len(dsts) > 1. While the code was correct, I broke it during a refactoring and tests didn't detect it. This fixes that glitch. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	ce45f4f3ff	wgengine/filter: inline ip6InList into match. matchIPsOnly gets 5% slower when inlining, despite significantly reduced memory ops and slightly tighter code. Part of #19.

Brad Fitzpatrick	19b0cfe89e	all: prepare for GOOS=ios in Go 1.16 Work with either way for now on iOS (darwin/arm64 vs ios/arm64). In February when Go 1.16 comes out we'll have a universal binary for darwin/arm64 (macOS) and will drop support for Go 1.15 and its darwin/amd64 meaning iOS. (it'll mean macOS).

Brad Fitzpatrick	450cfedeba	wgengine/magicsock: quiet an IPv6 warning in tests In tests, we force binding to localhost to avoid OS firewall warning dialogs. But for IPv6, we were trying (and failing) to bind to 127.0.0.1. You'd think we'd just say "localhost", but that's apparently ill defined. See https://tools.ietf.org/html/draft-ietf-dnsop-let-localhost-be-localhost and golang/go#22826. (It's bitten me in the past, but I can't remember specific bugs.) So use "::1" explicitly for "udp6", which makes the test quieter.	4 years ago

David Anderson	c48253e63b	wgengine/filter: add a method to run the packet filter without a packet. The goal is to move some of the shenanigans we have elsewhere into the filter package, so that all the weird things to do with poking at the filter is in a single place, behind clean APIs.

David Anderson	b3634f020d	wgengine/filter: use netaddr types in public API. We still use the packet.* alloc-free types in the data path, but the compilation from netaddr to packet happens within the filter package. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
