Brad Fitzpatrick	9497921f52	logpolicy: also set up TLS dialing (for iOS) for log uploads This was the last of the three places that do TLS from clients (logs, control, derp). With this, iOS should be able to use the memory-efficient x509 root CertPool.	5 years ago
Brad Fitzpatrick	c726c1eec9	logtail: add const DefaultHost with default server name	5 years ago
Brad Fitzpatrick	1a0f6fea58	go.mod, go.sum: bump wireguard-go, tidy	5 years ago
Brad Fitzpatrick	95a658e1e3	control/controlclient: also rename HTTPC in the tests	5 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.)	5 years ago
Brad Fitzpatrick	6fcbd4c4d4	net/tlsdial: add memory-optimized TLS cert verification path for iOS Behind a build tag for now.	5 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.	5 years ago

Brad Fitzpatrick	8fd8fc9c7d	tempfork/x509: fix build on darwin and windows These fixes were originally in the updates to CL 229917 after Trybots failed there. See https://go-review.googlesource.com/c/go/+/229917/1..3	5 years ago
Brad Fitzpatrick	bfc1261ab6	crypto/x509: keep smaller root cert representation in memory until needed (from patchset 1, c12c890c64dd6372b3893af1e6f5ab11802c9e81, of https://go-review.googlesource.com/c/go/+/230025/1, with merges fixes due to parent commit's differents from its ps1..ps3) Instead of parsing the PEM files and then storing the *Certificate values forever, still parse them to see if they're valid and pick out some fields, but then only store the decoded pem.Block.Bytes until that cert is first needed. Saves about 500K of memory on my (Debian stable) machine after doing a tls.Dial or calling x509.SystemCertPool. A more aggressive version of this is still possible: we can not keep the pem.Block.Bytes in memory either, and re-read them from disk when necessary. But dealing with files disappearing and even large multi-cert PEM files changing (with offsets sliding around) made this conservative version attractive. It doesn't change the slurp-roots-on-startup semantics. It just does so with less memory retained. Change-Id: I3aea333f4749ae3b0026042ec3ff7ac015c72204	5 years ago
Brad Fitzpatrick	f5993f2440	crypto/x509: add support for CertPool to load certs lazily (from patchset 1, 7cdc3c3e7427c9ef69e19224d6036c09c5ea1723, of https://go-review.googlesource.com/c/go/+/229917/1) This will allow building CertPools that consume less memory. (Most certs are never accessed. Different users/programs access different ones, but not many.) This CL only adds the new internal mechanism (and uses it for the old AddCert) but does not modify any existing root pool behavior. (That is, the default Unix roots are still all slurped into memory as of this CL) Change-Id: Ib3a42e4050627b5e34413c595d8ced839c7bfa14	5 years ago
Brad Fitzpatrick	6b232b5a79	Disable staticcheck for tempfork packages.	5 years ago
Numerous Gophers	3bab226299	Add fork of Go 1.15-dev's crypto/x509 Snapshotted from Go commit 619c7a48a38b28b521591b490fd14ccb7ea5e821 (https://go-review.googlesource.com/c/go/+/229762, "crypto/x509: add x509omitbundledroots build tag to not embed roots") With 975c01342a25899962969833d8b2873dc8856a4f (https://go-review.googlesource.com/c/go/+/220721) removed, because it depends on other stuff in Go std that doesn't yet exist in a Go release. Also, add a subset fork of Go's internal/testenv, for use by x509's tests.	5 years ago

David Crawshaw	5b95aa81ea	wgengine: remove IpcSetOperation on LinkChange This was only done occasionally, but was extremely disruptive when done and is no longer necessary. It used to be that when switching links, we had to immediately generate handshakes to everyone we were communicating with to punch a hole in any NAT we were talking through. (This ended up not really working, because in the process we got rid of our session keys and ended up having a futile conversation for many seconds.) Now we have DERP, our link change propogates to the other side as a new list of endpoints, so they start spraying packets. We will definitely get one thanks to DERP, which will cause us to spray, opening any NAT we are behind. The result is that for good connections, we don't trash session keys and cause an interruption.

Brad Fitzpatrick	922d9546bf	wgengine: don't allocate so much in userspaceEngine.getStatus It was one of the top garbage producers on my phone. It's slated to be deleted and replaced anyway, but this helps in the meantime. The go.sum changes look scary, but the new dep only adds 240 bytes to the binary. The go.sum noise is just cmd/go being aggressive in including a lot of stuff (which is being fixed in Go 1.15, for what I understand). And I ran a go mod tidy, which added some too. (I had to write a custom wrapper around go mod tidy because this mod tidy normally breaks on tailscale.io/control being missing but referenced in tests) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
