Dmytro Shynkevych	d9a7205be5	net/tstun: set link speed to SPEED_UNKNOWN ... Fixes #3933. Signed-off-by: Dmytro Shynkevych <dm.shynk@gmail.com>	3 years ago
Brad Fitzpatrick	41fd4eab5c	envknob: add new package for all the strconv.ParseBool(os.Getenv(..)) ... A new package can also later record/report which knobs are checked and set. It also makes the code cleaner & easier to grep for env knobs. Change-Id: Id8a123ab7539f1fadbd27e0cbeac79c2e4f09751 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	9b101bd6af	net/tstun: don't compile the code New constructor on js/wasm ... Updates #3157 Change-Id: I81603edf3e69e6f1517b0074eef6b648f2981c50 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	e804ab29fd	net/tstun: move TUN failure diagnostics to OS-specific files ... Mostly so the Linux one can use Linux-specific stuff in package syscall and not use os/exec for uname for portability. But also it helps deps a tiny bit on iOS.

Brad Fitzpatrick	a729070252	net/tstun: add start of Linux TAP support, with DHCP+ARP server ... Still very much a prototype (hard-coded IPs, etc) but should be non-invasive enough to submit at this point and iterate from here. Updates #2589 Co-Author: David Crawshaw <crawshaw@tailscale.com> Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Anderson	df8a5d09c3	net/tstun: add a debug envvar to override tun MTU. ... Signed-off-by: David Anderson <dave@natulte.net>	4 years ago
Josh Bleecher Snyder	1ece91cede	go.mod: upgrade wireguard-windows, de-fork wireguard-go ... Pull in the latest version of wireguard-windows. Switch to upstream wireguard-go. This requires reverting all of our import paths. Unfortunately, this has to happen at the same time. The wireguard-go change is very low risk, as that commit matches our fork almost exactly. (The only changes are import paths, CI files, and a go.mod entry.) So if there are issues as a result of this commit, the first place to look is wireguard-windows changes.

David Anderson	bc4381447f	net/tstun: return the real interface name at device creation. ... This is usually the same as the requested interface, but on some unixes can vary based on device number allocation, and on Windows it's the GUID instead of the pretty name, since everything relating to configuration wants the GUID.

David Anderson	22d53fe784	net/tstun: document exported function. ... Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	018200aeba	net/tstun: rename from net/tun. ... We depend on wireguard-go/tun, identical leaf packages can be confusing in code. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
