Avery Pennarun	f53e78e0d5	wgengine: don't lose filter state on filter reconfig. We were abandoning the UDP port LRU every time we got a new packet filter from tailcontrol, which caused return packets to suddenly stop arriving.	5 years ago
Avery Pennarun	4336de0d98	ipn/local: don't print packet filter every single time. It's extremely noisy right now for domains with complex ACLs.	5 years ago
Brad Fitzpatrick	7740cbd8d9	ipn: call SetNetInfoCallback later, in Start It was being called back into ultimately from magicsock before there was a control client. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	51b669e4bd	ipn: skip tailscaled UDP ports in service list	5 years ago
David Crawshaw	addbdce296	wgengine, ipn: include number of active DERPs in status Use this when making the ipn state transition from Starting to Running. This way a network of quiet nodes with no active handshaking will still transition to Active. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
Brad Fitzpatrick	120273d7f6	portlist: document, clean up, fix an open fd spike, optimize a bit I noticed portlist when looking at some profiles and hadn't looked at the code much before. This is a first pass over it. It allocates a fair bit. More love remains, but this does a bit: name old time/op new time/op delta GetList-8 9.92ms ± 8% 9.64ms ±12% ~ (p=0.247 n=10+10) name old alloc/op new alloc/op delta GetList-8 931kB ± 0% 869kB ± 0% -6.70% (p=0.000 n=10+10) name old allocs/op new allocs/op delta GetList-8 4.59k ± 0% 3.69k ± 1% -19.71% (p=0.000 n=10+10) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	42e98d4edc	Quiet two little log annoyances.	5 years ago
David Anderson	aeb88864e0	ipn: don't clobber netinfo in Start().	5 years ago
Avery Pennarun	b4897e7de8	controlclient/netmap: write our own b.ConciseDiffFrom(a) function. This removes the need for go-cmp, which is extremely bloaty so we had to leave it out of iOS. As a result, we had also left it out of macOS, and so we didn't print netmap diffs at all on darwin-based platforms. Oops. As a bonus, the output format of the new function is way better. Minor oddity: because I used the dumbest possible diff algorithm, the sort order is a bit dumb. We print all "removed" lines and then print all "added" lines, rather than doing the usual diff-like thing of interspersing them. This probably doesn't matter (maybe it's an improvement).	5 years ago

Brad Fitzpatrick	25797c8c2a	all: rename deep "Copy" methods to conventional Go name "Clone"	5 years ago
Brad Fitzpatrick	14559340ee	Start of netcheck package & including network state in Hostinfo. * adds new packet "netcheck" to do the checking of UDP, IPv6, and nearest DERP server, and the Report type for all that (and more in the future, probably pulling in danderson's natprobe) * new tailcfg.NetInfo type * cmd/tailscale netcheck subcommand (tentative name, likely to change/move) to print out the netcheck.Report.

David Anderson	c47f907a27	ipn: use *Prefs rather than Prefs throughout. Prefs has become a heavy object with non-memcpy copy semantics. We should not pass such a thing by value. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	0c55777fed	ipn: temporary support for loading legacy relaynode configs. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	cf1e386cbd	ipn: move Options.ServerURL into Prefs. We can't rely on a frontend to provide a control server URL, so this naturally belongs in server-persisted state. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	47da432991	ipn: handle advertised routes provided by frontend. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago

David Anderson	5f45b7c765	ipn: make LocalBackend.loadStateWithLock easier to follow. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	5bc632271b	Introduce a state store to LocalBackend. The store is passed-in by callers of NewLocalBackend and ipnserver.Run, but currently all callers are hardcoded to an in-memory store. The store is unused. Signed-Off-By: David Anderson <dave@natulte.net>	5 years ago
David Anderson	21280ca2d1	Make ipn.Options.Prefs a pointer. This is a prelude to making it truly optional, once state management has moved into the backend. For now though, it's still required. This change is just isolating the bubbling-up of the pointerification into other layers. Signed-Off-By: David Anderson <dave@natulte.net>	5 years ago
David Anderson	f6f154193f	Remove LoginFlags from Backend options. - It was only used in one currently-unused client. - It's an imperative command, not a configuration setting. - The LoginFlags stuff in controlclient feels like it needs a refactor anyway. I'll put this logic back once ipnd owns its state and Backend commands reflect that. Signed-Off-By: David Anderson <dave@natulte.net>	5 years ago
