Avery Pennarun	99aa33469e	cmd/tailscale: be quiet when no interaction or errors are needed. We would print a message about "nothing more to do", which some people thought was an error or warning. Let's only print a message after authenticating if we previously asked for interaction, and let's shorten that message to just "Success," which is what it means.

Avery Pennarun	30e5c19214	magicsock: work around race condition initializing .Regions[]. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	7cd9ff3dde	net/netcheck: fix race condition initializting RegionLatency maps. Under some conditions, code would try to look things up in the maps before the first call to updateLatency. I don't see any reason to delay initialization of the maps, so let's just init them right away when creating the Report instance. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago

David Anderson	2b74236567	ipn: move e2e_test back to corp repo. It depends on corp things, so can't run here anyway. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	557b310e67	control/controlclient: move auto_test back to corp repo. It can't run without corp stuff anyway, and makes it harder to refactor the control server.	4 years ago

David Anderson	7317e73bf4	control/controlclient: move direct_test back to corp repo. It can only be built with corp deps anyway, and having it split from the control code makes our lives harder. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Brad Fitzpatrick	3f4a567032	types/strbuilder: add a variant of strings.Builder that uses sync.Pool ... and thus does not need to worry about when it escapes into unprovable fmt interface{} land. Also, add some convenience methods for efficiently writing integers.	4 years ago
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. Fixes #387 (Don't hard-code the DERP map) Updates #388 (Add DERP region support) Fixes #399 (wgengine: flaky tests) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago

Avery Pennarun	ea8f92b312	ipn/local: get rid of some straggling calls to the log module. Use b.logf() instead. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	af9328c1b7	log rate limiting: reformat limiter messages, and use nonempty burst size. - Reformat the warning about a message being rate limited to print the format string, rather than the formatted message. This helps give a clue what "type" of message is being limited. - Change the rate limit warning to be [RATE LIMITED] in all caps. This uses less space on each line, plus is more noticeable. - In tailscaled, change the frequency to be less often (once every 5 seconds per format string) but to allow bursts of up to 5 messages. This greatly reduces the number of messages that are rate limited during startup, but allows us to tighten the limit even further during normal runtime.

Avery Pennarun	f2db4ac277	cmd/tailscaled: SetGCPercent() if GOGC is not set. This cuts RSS from ~30MB to ~20MB on my machine, after the previous fix to get rid of unnecessary zstd buffers. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
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	1013cda799	controlclient/auto_test: don't print the s.control object. This contains atomic ints that trigger a race check error if we access them non-atomically. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	806de4ac94	portlist: fix "readdirent: no such file or directory" errors on Linux. This could happen when a process disappeared while we were reading its file descriptor list. I was able to replicate the problem by running this in another terminal: while :; do for i in $(seq 10); do /bin/true & done >&/dev/null; wait >&/dev/null; done And then running the portlist tests thousands of times.

David Anderson	9c914dc7dd	wgengine/router: stop using -m comment. The comment module is compiled out on several embedded systems (and also gentoo, because netfilter can't go brrrr with comments holding it back). Attempting to use comments results in a confusing error, and a non-functional firewall. Additionally, make the legacy rule cleanup non-fatal, because we do have to probe for the existence of these -m comment rules, and doing so will error out on these systems.

Avery Pennarun	d0754760e7	controlclient/auto_test: fix flake "peer OS is not linux" on macOS. We were mis-counting the number of Synchronized messages that we should have been generating.	5 years ago
Avery Pennarun	8f8607b6bf	control/controlclient/auto_test: clean up logging to defeat 'go test' idiocy. By default, nothing differentiates errors or fatals from regular logs, so they just blend into the rest of the logs. As a bonus, if you run a test using t.Run(), the log messages printed via the sub-t.Run() are printed at a different time from log messages printed via the parent t.Run(), making debugging almost impossible. This doesn't actually fix the test flake I'm looking for, but at least I can find it in the logs now. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	d53e8fc0da	router_darwin_support: we can build this on every platform. Our new build scripts try to build ipn-go-bridge on more than just linux and darwin, so let's enable this file so it can be successful on every platform.	5 years ago

Brad Fitzpatrick	040a0d5121	derp/derphttp: don't use x/net/proxy for SOCKS on iOS We don't want those extra dependencies on iOS, at least yet. Especially since there's no way to set the relevant environment variables so it's just bloat with no benefits. Perhaps we'll need to do SOCKS on iOS later, but probably differently if/when so.
