Josh Bleecher Snyder	7693d36aed	all: close fake userspace engines when tests complete We were leaking FDs. In a few places, switch from defer to t.Cleanup. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	4c68b7df7c	tstest: add MemLogger bytes.Buffer wrapper with Logf method We use it tons of places. Updated three at least in this PR. Another use in next commit. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Josh Bleecher Snyder	4954fbfda6	wgengine: extend TestWatchdog timeout on macOS This works around the close syscall being slow. We can revert this if we find a fix or if Apple makes close fast again. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	38dc6fe758	cmd/tailscaled, wgengine: remove --fake, replace with netstack And add a --socks5-server flag. And fix a race in SOCKS5 replies where the response header was written concurrently with the copy from the backend. Co-authored with Naman Sood. Updates #707 Updates #504 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	5aa5db89d6	cmd/tailscaled, wgengine/netstack: add start of gvisor userspace netstack work Not usefully functional yet (mostly a proof of concept), but getting it submitted for some work @namansood is going to do atop this.

Dmytro Shynkevych	e9643ae724	wgengine: prevent log after exit in watchdog test Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	511840b1f6	tsdns: initial implementation of a Tailscale DNS resolver (#396 ) Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	5 years ago
Brad Fitzpatrick	becce82246	net/netns, misc tests: remove TestOnlySkipPrivilegedOps, argv checks The netns UID check is sufficient for now. We can do something else later if/when needed.	5 years ago
David Anderson	5114df415e	net/netns: set the bypass socket mark on linux. This allows tailscaled's own traffic to bypass Tailscale-managed routes, so that things like tailscale-provided default routes don't break tailscaled itself. Progress on #144.

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.

David Anderson	1ac570def7	wgengine/router: split out from wgengine. The router implementations are logically separate, with their own API. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
Brad Fitzpatrick	79295b1138	wgengine: simplify, change some signatures * make RouterGen return an error, not take both tunname and tundev * also remove RouteGen taking a wireguard/device.Device; currently unused * remove derp parameter (it'll work differently) * unexport NewUserspaceRouter in per-OS impls, add documented wrapper Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
