Brad Fitzpatrick	3672f29a4e	net/netns, net/dns/resolver, etc: make netmon required in most places The goal is to move more network state accessors to netmon.Monitor where they can be cheaper/cached. But first (this change and others) we need to make sure the one netmon.Monitor is plumbed everywhere. Some notable bits: * tsdial.NewDialer is added, taking a now-required netmon * because a tsdial.Dialer always has a netmon, anything taking both a Dialer and a NetMon is now redundant; take only the Dialer and get the NetMon from that if/when needed. * netmon.NewStatic is added, primarily for tests Updates tailscale/corp#10910 Updates tailscale/corp#18960 Updates #7967 Updates #3299 Change-Id: I877f9cb87618c4eb037cee098241d18da9c01691 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	7 months ago

Brad Fitzpatrick	b27238b654	derp/derphttp: don't block in LocalAddr method The derphttp.Client mutex is held during connects (for up to 10 seconds) so this LocalAddr method (blocking on said mutex) could also block for up to 10 seconds, causing a pileup upstream in magicsock/wgengine and ultimately a watchdog timeout resulting in a crash.

Brad Fitzpatrick	b2b836214c	derp/derphttp: fix derptrack fix `3d7fb6c21d` dropped the explicit called to (Client).connect when its (Client).WatchConnectionChanges got removed+refactored. This puts it back, but in RunWatchConnectionLoop, before the call to the (*Client).ServerPublicKey accessor, which is documented to return the zero value (which is what broke us) on an unconnected connection. Plus some tests. Fixes tailscale/corp#15604 Change-Id: I0f242816f5ee4ad3bb0bf0400abc961dbe9f5fc8 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

Brad Fitzpatrick	cf8dd7aa09	all: use Go 1.20's bytes.Clone Updates #7123 Updates #6257 (more to do in other repos) Change-Id: I073e2a6d81a5d7fbecc29caddb7e057ff65239d0 Signed-off-by: Brad Fitzpatrick <bradfitz@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
Brad Fitzpatrick	535b925d1b	derp/derphttp: add Client.Ping, SendPing methods Continuing work in `434af15a04`, to make it possible for magicsock to probe whether a DERP server is still there.

Brad Fitzpatrick	6b80bcf112	derp: remove a client round-trip waiting on serverInfo It just has a version number in it and it's not really needed. Instead just return it as a normal Recv message type for those that care (currently only tests). Updates #150 (in that it shares the same goal: initial DERP latency) Updates #199 (in that it removes some DERP versioning)	4 years ago
Brad Fitzpatrick	abd79ea368	derp: reduce DERP memory use; don't require callers to pass in memory to use The magicsock derpReader was holding onto 65KB for each DERP connection forever, just in case. Make the derp{,http}.Client be in charge of memory instead. It can reuse its bufio.Reader buffer space.	5 years ago
Brad Fitzpatrick	becce82246	net/netns, misc tests: remove TestOnlySkipPrivilegedOps, argv checks The netns UID check is sufficient for now. We can do something else later if/when needed.	5 years ago
David Anderson	5114df415e	net/netns: set the bypass socket mark on linux. This allows tailscaled's own traffic to bypass Tailscale-managed routes, so that things like tailscale-provided default routes don't break tailscaled itself. Progress on #144.
