Andrea Barisani	0a74d46568	adjust build tags for tamago Signed-off-by: Andrea Barisani <andrea@inversepath.com>	1 year ago
David Anderson	8b492b4121	net/wsconn: accept a remote addr string and plumb it through This makes wsconn.Conns somewhat present reasonably when they are the client of an http.Request, rather than just put a placeholder in that field. Updates tailscale/corp#13777 Signed-off-by: David Anderson <danderson@tailscale.com>	1 year ago
Brad Fitzpatrick	11ece02f52	net/{interfaces,netmon}: remove "interesting", EqualFiltered API This removes a lot of API from net/interfaces (including all the filter types, EqualFiltered, active Tailscale interface func, etc) and moves the "major" change detection to net/netmon which knows more about the world and the previous/new states. Updates #9040 Change-Id: I7fe66a23039c6347ae5458745b709e7ebdcce245 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Joe Tsai	fcbb2bf348	net/memnet: export the network name (#9111 ) This makes it more maintainable for other code to statically depend on the exact value of this string. It also makes it easier to identify what code might depend on this string by looking up references to this constant. Updates tailscale/corp#13777 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	1 year ago
Andrew Dunham	c86a610eb3	cmd/tailscale, net/portmapper: add --log-http option to "debug portmap" This option allows logging the raw HTTP requests and responses that the portmapper Client makes when using UPnP. This can be extremely helpful when debugging strange UPnP issues with users' devices, and might allow us to avoid having to instruct users to perform a packet capture. Updates #8992 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I2c3cf6930b09717028deaff31738484cc9b008e4	1 year ago
Brad Fitzpatrick	98a5116434	all: adjust some build tags for plan9 I'm not saying it works, but it compiles. Updates #5794 Change-Id: I2f3c99732e67fe57a05edb25b758d083417f083e Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Brad Fitzpatrick	d58ba59fd5	cmd/tailscale/cli: make netcheck run even if machine lacks TLS certs We have a fancy package for doing TLS cert validation even if the machine doesn't have TLS certs (for LetsEncrypt only) but the CLI's netcheck command wasn't using it. Also, update the tlsdial's outdated package docs while here. Updates #cleanup Change-Id: I74b3cb645d07af4d8ae230fb39a60c809ec129ad Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Brad Fitzpatrick	e881c1caec	net/netmon: factor out debounce loop, simplify polling impl This simplifies some netmon code in prep for other changes. It breaks up Monitor.debounce into a helper method so locking is easier to read and things unindent, and then it simplifies the polling netmon implementation to remove the redundant stuff that the caller (the Monitor.debounce loop) was already basically doing. Updates #9040 Change-Id: Idcfb45201d00ae64017042a7bdee6ef86ad37a9f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Brad Fitzpatrick	9089efea06	net/netmon: make ChangeFunc's signature take new ChangeDelta, not bool Updates #9040 Change-Id: Ia43752064a1a6ecefc8802b58d6eaa0b71cf1f84 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Andrew Dunham	77ff705545	net/portmapper: never select port 0 in UPnP Port 0 is interpreted, per the spec (but inconsistently among router software) as requesting to map every single available port on the UPnP gateway to the internal IP address. We'd previously avoided picking ports below 1024 for one of the two UPnP methods (in #7457), and this change moves that logic so that we avoid it in all cases. Updates #8992 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I20d652c0cd47a24aef27f75c81f78ae53cc3c71e	1 year ago
Brad Fitzpatrick	58a4fd43d8	types/netmap, all: use read-only tailcfg.NodeView in NetworkMap Updates #8948 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Brad Fitzpatrick	6e57dee7eb	cmd/viewer, types/views, all: un-special case slice of netip.Prefix Make it just a views.Slice[netip.Prefix] instead of its own named type. Having the special case led to circular dependencies in another WIP PR of mine. Updates #8948 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
David Anderson	e92adfe5e4	net/art: allow non-pointers as values Values are still turned into pointers internally to maintain the invariants of strideTable, but from the user's perspective it's now possible to tbl.Insert(pfx, true) rather than tbl.Insert(pfx, ptr.To(true)). Updates #7781 Signed-off-by: David Anderson <danderson@tailscale.com>	1 year ago
Brad Fitzpatrick	e8551d6b40	all: use Go 1.21 slices, maps instead of x/exp/{slices,maps} Updates #8419 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
David Anderson	623d72c83b	net/art: move child table pointers out of strideEntry In preparation for a different refactor, but incidentally also saves 10-25% memory on overall table size in benchmarks. Updates #7781 Signed-off-by: David Anderson <danderson@tailscale.com>	1 year ago
James Tucker	de8e55fda6	net/netcheck,wgengine/magicsock: reduce coupling between netcheck and magicsock Netcheck no longer performs I/O itself, instead it makes requests via SendPacket and expects users to route reply traffic to ReceiveSTUNPacket. Netcheck gains a Standalone function that stands up sockets and goroutines to implement I/O when used in a standalone fashion. Magicsock now unconditionally routes STUN traffic to the netcheck.Client that it hosts, and plumbs the send packet sink. The CLI is updated to make use of the Standalone mode. Fixes #8723 Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
Maisem Ali	98ec8924c2	ipn/ipnlocal,net/tsdial: update docs/rename funcs Updates #cleanup Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Will Norris	69f1324c9e	cmd/tailscale: refactor shared utility methods Refactor two shared functions used by the tailscale cli, calcAdvertiseRoutes and licensesURL. These are used by the web client as well as other tailscale subcommands. The web client is being moved out of the cli package, so move these two functions to new locations.

David Anderson	1e6f0bb608	net/art: fix slowPrefixTable bugs found by fuzzing One is a straight "I forgot how to Go" bug, the others are semantic mismatches with the main implementation around masking the prefixes passed to insert/delete.

Michael Stapelberg	2a6c237d4c	net/dns: overwrite /tmp/resolv.conf on gokrazy Appliances built using https://gokrazy.org/ have a read-only root file system, including /etc/resolv.conf, which is a symlink to /tmp/resolv.conf. The system’s dhcp client overwrites /tmp/resolv.conf instead, so we need to use this path in Tailscale, too. related to https://github.com/gokrazy/gokrazy/issues/209 fixes https://github.com/tailscale/tailscale/issues/8689 Signed-off-by: Michael Stapelberg <michael@stapelberg.de>	1 year ago
Anton Tolchanov	388b124513	net/dns: detect when libnss_resolve is used Having `127.0.0.53` is not the only way to use `systemd-resolved`. An alternative way is to enable `libnss_resolve` module, which seems to now be used by default on Debian 12 bookworm. Fixes #8549 Signed-off-by: Anton Tolchanov <anton@tailscale.com>	1 year ago
Andrew Dunham	9b5e29761c	net/netcheck: ignore PreferredDERP changes that are small If the absolute value of the difference between the current PreferredDERP's latency and the best latency is <= 10ms, don't change it and instead prefer the previous value. This is in addition to the existing hysteresis that tries to remain on the previous DERP region if the relative improvement is small, but handles nodes that have low latency to >1 DERP region better.

Andrew Dunham	7aba0b0d78	net/netcheck, tailcfg: add DERPHomeParams and use it This allows providing additional information to the client about how to select a home DERP region, such as preferring a given DERP region over all others.

Andrew Dunham	a7648a6723	net/dnsfallback: run recursive resolver and compare results When performing a fallback DNS query, run the recursive resolver in a separate goroutine and compare the results returned by the recursive resolver with the results we get from "regular" bootstrap DNS. This will allow us to gather data about whether the recursive DNS resolver works better, worse, or about the same as "regular" bootstrap DNS.

Adrian Dewhurst	cd4c71c122	tstest: prepare for Clock API changes This change introduces tstime.NewClock and tstime.ClockOpts as a new way to construct tstime.Clock. This is a subset of #8464 as a stepping stone so that we can update our internal code to use the new API before making the second round of changes.
