Maisem Ali	04b57a371e	ipn/ipnlocal: drop not required StateKey parameter This is #cleanup now that #7121 is merged. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Will Norris	71029cea2d	all: update copyright and license headers 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>	2 years ago
Andrew Dunham	58ad21b252	wgengine/netstack: fix data race in tests 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	2 years ago
Claire Wang	a45c9f982a	wgengine/netstack: change netstack API to require LocalBackend 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>	2 years ago
Brad Fitzpatrick	caa2fe394f	wgengine/netstack: delete some dead code, old comment, use atomic int types Noticed while looking at something else; #cleanup. Change-Id: Icde7749363014eab9bebe1dd80708f5491f933d1 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
andig	14e8afe444	go.mod, etc: bump gvisor Fixes #6554 Change-Id: Ia04ae37a47b67fa57091c9bfe1d45a1842589aa8 Signed-off-by: andig <cpuidle@gmx.de>	2 years ago
Maisem Ali	18c7c3981a	ipn/ipnlocal: call checkPrefs in Start too We were not calling checkPrefs on `opts.Prefs` in (LocalBackend).Start(). Updates #713 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Maisem Ali	4d330bac14	ipn/ipnlocal: add support for multiple user profiles Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Brad Fitzpatrick	79472a4a6e	wgengine/netstack: optimize shouldProcessInbound, avoiding 4via6 lookups 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.

Andrew Dunham	acf5839dd2	wgengine/netstack: add tests for shouldProcessInbound 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>	2 years ago
Andrew Dunham	0607832397	wgengine/netstack: always respond to 4via6 echo requests (#5712 ) 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>	2 years ago
Andrew Dunham	b9b0bf65a0	wgengine/netstack: handle 4via6 packets when pinging (#5709 ) Change-Id: Ib6ebbaa11219fb91b550ed7fc6ede61f83262e89 Signed-off-by: Andrew Dunham <andrew@tailscale.com>	2 years ago
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	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
Tom DNetto	7f45734663	assorted: documentation and readability fixes This were intended to be pushed to #4408, but in my excitement I forgot to git push :/ better late than never. Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
Tom DNetto	9e77660931	net/tstun,wgengine/{.,netstack}: handle UDP magicDNS traffic in netstack 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>	3 years ago
James Tucker	c6ac29bcc4	wgengine/netstack: disable refsvfs2 leak tracking (#4378 ) 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>	3 years ago
Josh Bleecher Snyder	0868329936	all: use any instead of interface{} My favorite part of generics. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	185825df11	wgengine/netstack: add a missing refcount decrement after packet injection Fixes #3762 Updates #3745 (probably fixes?) Change-Id: I1d3f0590fd5b8adfbc9110bc45ff717bb9e79aae Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	d5405c66b7	net/tsdial: start of new package to unify all outbound dialing complexity 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.

Brad Fitzpatrick	722859b476	wgengine/netstack: make SOCKS5 resolve names to IPv6 if self node when no IPv4 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>	3 years ago
