Brad Fitzpatrick	8edcab04d5	log/logheap: change to POST to a URL instead of logging It's too big to log.	4 years ago
Brad Fitzpatrick	24009241bf	net/netns: move SOCKS dialing to netns for now This lets control & logs also use SOCKS dials. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	f0204098d8	Revert "control/controlclient: use "getprop net.hostname" for Android hostname" This reverts commit `afb9c6a6ab`. Doesn't work. See: https://github.com/tailscale/tailscale/issues/409#issuecomment-635241550 Looks pretty dire: https://medium.com/capital-one-tech/how-to-get-an-android-device-nickname-d5eab12f4ced Updates #409	4 years ago

Brad Fitzpatrick	703d789005	tailcfg: add MapResponse.Debug mechanism to trigger logging heap pprof Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	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>	4 years ago
Avery Pennarun	c5fcc38bf1	controlclient tests: fix more memory leaks and add resource checking. I can now run these tests with -count=1000 without running out of RAM. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago

Brad Fitzpatrick	fefd7e10dc	types/structs: add structs.Incomparable annotation, use it where applicable Shotizam before and output queries: sqlite> select sum(size) from bin where func like 'type..%'; 129067 => 120216	4 years ago
Avery Pennarun	65fbb9c303	wgengine/filter: support subnet mask rules, not just /32 IPs. This depends on improved support from the control server, to send the new subnet width (Bits) fields. If these are missing, we fall back to assuming their value is /32. Conversely, if the server sends Bits fields to an older client, it will interpret them as /32 addresses. Since the only rules we allow are "accept" rules, this will be narrower or equal to the intended rule, so older clients will simply reject hosts on the wider subnet (fail closed). With this change, the internal filter.Matches format has diverged from the wire format used by controlclient, so move the wire format into tailcfg and convert it to filter.Matches in controlclient.

Brad Fitzpatrick	172d72a060	Revert "net/tlsdial: add memory-optimized TLS cert verification path for iOS" This reverts commit `6fcbd4c4d4`. Decided to put it in tailscale/go's crypto/x509 instead.	4 years ago
Brad Fitzpatrick	eb6de2bd88	control/controlclient: restore Options.HTTPC as Options.HTTPTestClient I removed the HTTPC field in `b6fa5a69be` but it was apparently still used in [oss-skipped] tests. Restore it, but name it so it's more obvious that it's only for tests. (It currently is, and I'd like to keep it like that for now.)	4 years ago
Brad Fitzpatrick	6fcbd4c4d4	net/tlsdial: add memory-optimized TLS cert verification path for iOS Behind a build tag for now.	4 years ago
Brad Fitzpatrick	b6fa5a69be	net/tlsdial: add package for TLS dials, and make DERP & controlclient use it This will do the iOS-optimized cert checking in a following change.	4 years ago

Brad Fitzpatrick	af277a6762	controlclient, magicsock: add debug knob to request IPv6 endpoints Add opt-in method to request IPv6 endpoints from the control plane. For now they should just be skipped. A previous version of this CL was unconditional and reportedly had problems that I can't reproduce. So make it a knob until the mystery is solved.

David Anderson	0be475ba46	Revert "tailcfg, controlclient, magicsock: request IPv6 endpoints, but ignore them" Breaks something deep in wireguard or magicsock's brainstem, no packets at all can flow.

Avery Pennarun	f2e2ffa423	controlclient: log the entire netmap up to every 5 minutes. We log it once upon receiving the first copy of the map, then subsequently when a new one appears, but only if we haven't logged one less than 5 minutes ago. This avoids overly cluttering the log (as we did before, logging the netmap every time one appeared, which could be hundreds of lines every few seconds), but still gives the log enough context to help in diagnosing problems retroactively.	4 years ago
