David Anderson	c71754eba2	ipn/ipnserver: revert decoder memory limit. ... The zstd library treats that limit as a hard cap on decompressed size, in the mode we're using it, rather than a window size. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Avery Pennarun	34c30eaea0	router_linux: use only baseline 'ip rule' features that exist in old kernels. ... This removes the use of suppress_ifgroup and fwmark "x/y" notation, which are, among other things, not available in busybox and centos6. We also use the return codes from the 'ip' program instead of trying to parse its output. I also had to remove the previous hack that routed all of 100.64.0.0/10 by default, because that would add the /10 route into the 'main' route table instead of the new table 88, which is no good. It was a terrible hack anyway; if we wanted to capture that route, we should have captured it explicitly as a subnet route, not as part of the addr. Note however that this change affects all platforms, so hopefully there won't be any surprises elsewhere.

Brad Fitzpatrick	e6b84f2159	all: make client use server-provided DERP map, add DERP region support ... Instead of hard-coding the DERP map (except for cmd/tailscale netcheck for now), get it from the control server at runtime. And make the DERP map support multiple nodes per region with clients picking the first one that's available. (The server will balance the order presented to clients for load balancing) This deletes the stunner package, merging it into the netcheck package instead, to minimize all the config hooks that would've been required. Also fix some test flakes & races.

Avery Pennarun	db051fb013	ipnserver and logpolicy: configure zstd with low-memory settings. ... The compressed blobs we send back and forth are small and infrequent, which doesn't justify the 8MB * GOMAXPROCS memory that was being allocated. This was the overwhelming majority of memory use in tailscaled. On my system it goes from ~100M RSS to ~15M RSS (which is still suspiciously high, but we can worry about that more later).

Avery Pennarun	08acb502e5	Add tstest.PanicOnLog(), and fix various problems detected by this. ... If a test calls log.Printf, 'go test' horrifyingly rearranges the output to no longer be in chronological order, which makes debugging virtually impossible. Let's stop that from happening by making log.Printf panic if called from any module, no matter how deep, during tests. This required us to change the default error handler in at least one http.Server, as well as plumbing a bunch of logf functions around, especially in magicsock and wgengine, but also in logtail and backoff. To add insult to injury, 'go test' also rearranges the output when a parent test has multiple sub-tests (all the sub-test's t.Logf is always printed after all the parent tests t.Logf), so we need to screw around with a special Logf that can point at the "current" t (current_t.Logf) in some places. Probably our entire way of using subtests is wrong, since 'go test' would probably like to run them all in parallel if you called t.Parallel(), but it definitely can't because the're all manipulating the shared state created by the parent test. They should probably all be separate toplevel tests instead, with common setup/teardown logic. But that's a job for another time. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago

Dmytro Shynkevych	33b2f30cea	wgengine: wrap tun.Device to support filtering and packet injection (#358) ... Right now, filtering and packet injection in wgengine depend on a patch to wireguard-go that probably isn't suitable for upstreaming. This need not be the case: wireguard-go/tun.Device is an interface. For example, faketun.go implements it to mock a TUN device for testing. This patch implements the same interface to provide filtering and packet injection at the tunnel device level, at which point the wireguard-go patch should no longer be necessary. This patch has the following performance impact on i7-7500U @ 2.70GHz, tested in the following namespace configuration: ┌────────────────┐ ┌─────────────────────────────────┐ ┌────────────────┐ │ $ns1 │ │ $ns0 │ │ $ns2 │ │ client0 │ │ tailcontrol, logcatcher │ │ client1 │ │ ┌─────┐ │ │ ┌──────┐ ┌──────┐ │ │ ┌─────┐ │ │ │vethc│───────┼────┼──│vethrc│ │vethrs│──────┼─────┼──│veths│ │ │ ├─────┴─────┐ │ │ ├──────┴────┐ ├──────┴────┐ │ │ ├─────┴─────┐ │ │ │10.0.0.2/24│ │ │ │10.0.0.1/24│ │10.0.1.1/24│ │ │ │10.0.1.2/24│ │ │ └───────────┘ │ │ └───────────┘ └───────────┘ │ │ └───────────┘ │ └────────────────┘ └─────────────────────────────────┘ └────────────────┘ Before: --------------------------------------------------- | TCP send | UDP send | |------------------------|------------------------| | 557.0 (±8.5) Mbits/sec | 3.03 (±0.02) Gbits/sec | --------------------------------------------------- After: --------------------------------------------------- | TCP send | UDP send | |------------------------|------------------------| | 544.8 (±1.6) Mbits/sec | 3.13 (±0.02) Gbits/sec | --------------------------------------------------- The impact on receive performance is similar.

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).	4 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>	4 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>	4 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>	4 years ago
David Anderson	81eedcd5be	ipnserver: ignore lint error for unused context. ... The linter is strictly correct, but the code is structured this way to avoid variable shadowing problems in the following for loop. The context doesn't leak. Staticcheck is correctly pointing out that this code is hard to follow. However, this chunk of code is in service of enforcing one frontend <> one backend, and we want to remove that limitation. So, we'll just ignore the lint warning until this entire piece of code goes away. Signed-off-by: David Anderson <dave@natulte.net>	4 years ago
