2023-09-17wgengine, proxymap: split out port mapping from Engine to new typeBrad Fitzpatrick1-2/+2
(Continuing quest to remove rando stuff from the "Engine") Updates #cleanup Change-Id: I77f39902c2194410c10c054b545d70c9744250b0 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2023-05-04tsd: add package with System type to unify subsystem init, discoveryBrad Fitzpatrick1-24/+18
This is part of an effort to clean up tailscaled initialization between tailscaled, tailscaled Windows service, tsnet, and the mac GUI. Updates #8036 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2023-03-23all: pass log IDs as the proper type rather than stringsWill Norris1-2/+3
This change focuses on the backend log ID, which is the mostly commonly used in the client. Tests which don't seem to make use of the log ID just use the zero value. Signed-off-by: Will Norris <will@tailscale.com>
2023-01-30ipn/ipnlocal: drop not required StateKey parameterMaisem Ali1-2/+2
This is #cleanup now that #7121 is merged. Signed-off-by: Maisem Ali <maisem@tailscale.com>
2023-01-27all: update copyright and license headersWill Norris1-3/+2
This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>
2023-01-19wgengine/netstack: fix data race in testsAndrew Dunham1-6/+2
This uses the helper function added in #6173 to avoid flakes like: https://github.com/tailscale/tailscale/actions/runs/3826912237/jobs/6511078024 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: If3f1d3b9c0f64ffcb4ba9a30d3522ec49484f993
2022-12-23wgengine/netstack: change netstack API to require LocalBackendClaire Wang1-46/+41
The macOS client was forgetting to call netstack.Impl.SetLocalBackend. Change the API so that it can't be started without one, eliminating this class of bug. Then update all the callers. Updates #6764 Change-Id: I2b3a4f31fdfd9fdbbbbfe25a42db0c505373562f Signed-off-by: Claire Wang <claire@tailscale.com> Co-authored-by: Brad Fitzpatrick <bradfitz@tailscale.com> Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2022-12-22wgengine/netstack: delete some dead code, old comment, use atomic int typesBrad Fitzpatrick1-3/+2
Noticed while looking at something else; #cleanup. Change-Id: Icde7749363014eab9bebe1dd80708f5491f933d1 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>

2022-11-22ipn/ipnlocal: call checkPrefs in Start tooMaisem Ali1-5/+10
We were not calling checkPrefs on `opts.*Prefs` in (*LocalBackend).Start(). Updates #713 Signed-off-by: Maisem Ali <maisem@tailscale.com>

2022-11-08wgengine/netstack: optimize shouldProcessInbound, avoiding 4via6 lookupsBrad Fitzpatrick1-1/+9
All IPv6 packets for the self address were doing netip.Prefix.Contains lookups. If if we know they're for a self address (which we already previously computed and have sitting in a bool), then they can't be for a 4via6 range. Change-Id: Iaaaf1248cb3fecec229935a80548ead0eb4cb892 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2022-11-08wgengine/netstack: add tests for shouldProcessInboundAndrew Dunham1-0/+221
Inspired by #6235, let's explicitly test the behaviour of this function to ensure that we're not processing things we don't expect to. Change-Id: I158050a63be7410fb99452089ea607aaf89fe91a Signed-off-by: Andrew Dunham <andrew@tailscale.com>
2022-09-21wgengine/netstack: always respond to 4via6 echo requests (#5712)Andrew Dunham1-30/+33
As the comment in the code says, netstack should always respond to ICMP echo requests to a 4via6 address, even if the netstack instance isn't normally processing subnet traffic. Follow-up to #5709 Change-Id: I504d0776c5824071b2a2e0e687bc33e24f6c4746 Signed-off-by: Andrew Dunham <andrew@tailscale.com>

2022-07-25all: convert more code to use net/netip directlyBrad Fitzpatrick1-2/+2
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.

2022-04-30assorted: documentation and readability fixesTom DNetto1-2/+2

2022-04-30net/tstun,wgengine/{.,netstack}: handle UDP magicDNS traffic in netstackTom DNetto1-2/+2
This change wires netstack with a hook for traffic coming from the host into the tun, allowing interception and handling of traffic to quad-100. With this hook wired, magicDNS queries over UDP are now handled within netstack. The existing logic in wgengine to handle magicDNS remains for now, but its hook operates after the netstack hook so the netstack implementation takes precedence. This is done in case we need to support platforms with netstack longer than expected. Signed-off-by: Tom DNetto <tom@tailscale.com>
2022-04-07wgengine/netstack: disable refsvfs2 leak tracking (#4378)James Tucker1-0/+10
In addition an envknob (TS_DEBUG_NETSTACK_LEAK_MODE) now provides access to set leak tracking to more useful values. Fixes #4309 Signed-off-by: James Tucker <james@tailscale.com>

2022-01-19wgengine/netstack: add a missing refcount decrement after packet injectionBrad Fitzpatrick1-0/+76
Fixes #3762 Updates #3745 (probably fixes?) Change-Id: I1d3f0590fd5b8adfbc9110bc45ff717bb9e79aae Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2021-11-30net/tsdial: start of new package to unify all outbound dialing complexityBrad Fitzpatrick1-112/+0
For now this just deletes the net/socks5/tssocks implementation (and the DNSMap stuff from wgengine/netstack) and moves it into net/tsdial. Then initialize a Dialer early in tailscaled, currently only use for the outbound and SOCKS5 proxies. It will be plumbed more later. Notably, it needs to get down into the DNS forwarder for exit node DNS forwading in netstack mode. But it will also absorb all the peerapi setsockopt and netns Dial and tlsdial complexity too.

2021-06-28wgengine/netstack: make SOCKS5 resolve names to IPv6 if self node when no IPv4Brad Fitzpatrick1-0/+112
For instance, ephemeral nodes with only IPv6 addresses can now SOCKS5-dial out to names like "foo" and resolve foo's IPv6 address rather than foo's IPv4 address and get a "no route" (*tcpip.ErrNoRoute) error from netstack's dialer. Per https://github.com/tailscale/tailscale/issues/2268#issuecomment-870027626 which is only part of the isuse. Updates #2268 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
