Brad Fitzpatrick	86e0f9b912	net/ipset, wgengine/filter/filtertype: add split-out packages ... This moves NewContainsIPFunc from tsaddr to new ipset package. And wgengine/filter types gets split into wgengine/filter/filtertype, so netmap (and thus the CLI, etc) doesn't need to bring in ipset, bart, etc. Then add a test making sure the CLI deps don't regress.

Maisem Ali	9a64c06a20	all: do not depend on the testing package ... Discovered while looking for something else. Updates tailscale/corp#18935 Signed-off-by: Maisem Ali <maisem@tailscale.com>	6 months ago
James Tucker	953fa80c6f	cmd/{derper,stund},net/stunserver: add standalone stun server ... Add a standalone server for STUN that can be hosted independently of the derper, and factor that back into the derper.

Maisem Ali	9d96e05267	net/packet: split off checksum munging into different pkg ... The current structure meant that we were embedding netstack in the tailscale CLI and in the GUIs. This removes that by isolating the checksum munging to a different pkg which is only called from `net/tstun`. Fixes #9756 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year 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	e85613aa2d	net/netcheck: don't use a space in the captive portal challenge ... The derpers don't allow whitespace in the challenge. Change-Id: I93a8b073b846b87854fba127b5c1d80db205f658 Signed-off-by: Andrew Dunham <andrew@tailscale.com>	2 years ago
Andrew Dunham	223126fe5b	cmd/derper, net/netcheck: add challenge/response to generate_204 endpoint ... The Lufthansa in-flight wifi generates a synthetic 204 response to the DERP server's /generate_204 endpoint. This PR adds a basic challenge/response to the endpoint; something sufficiently complicated that it's unlikely to be implemented by a captive portal. We can then check for the expected response to verify whether we're being MITM'd.

Brad Fitzpatrick	0be26599ca	cmd/derper: refactor STUN path for testing, add serverSTUN benchmark ... Real goal is to eliminate some allocs in the STUN path, but that requires work in the standard library. See comments in #2783. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	484b7fc9a3	derp, cmd/derper: add frameWatchConns, framePeerPresent for inter-DERP routing ... This lets a trusted DERP client that knows a pre-shared key subscribe to the connection list. Upon subscribing, they get the current set of connected public keys, and then all changes over time. This lets a set of DERP server peers within a region all stay connected to each other and know which clients are connected to which nodes.
