Brad Fitzpatrick	ace2faf7ec	cmd/tailscale: make debug profiling output - mean stdout Because the macOS CLI runs in the sandbox, including the filesystem, so users would be confused that -cpu-profile=prof.cpu succeeds but doesn't write to their current directory, but rather in some random Library/Containers directory somewhere on the machine (which varies depending on the Mac build type: App Store vs System Extension) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	efb84ca60d	ipn/localapi, cmd/tailscale: add CPU & memory profile support, debug command This was already possible on Linux if you ran tailscaled with --debug (which runs net/http/pprof), but it requires the user have the Go toolchain around. Also, it wasn't possible on macOS, as there's no way to run the IPNExtension with a debug server (it doesn't run tailscaled). And on Windows it's super tedious: beyond what users want to do or what we want to explain. Instead, put it in "tailscale debug" so it works and works the same on all platforms. Then we can ask users to run it when we're debugging something and they can email us the output files. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Denton Gentry	27bc4e744c	cmd/tailscale/web: support TLS from env vars. pfSense stores its SSL certificate and key in the PHP config. We wrote PHP code to pull the two out of the PHP config and into environment variables before running "tailscale web". The pfSense web UI is served over https, we need "tailscale web" to also support https in order to put it in an <iframe>. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Brad Fitzpatrick	9ca334a560	cmd/tailscaled: appease a security scanner There are two reasons this can't ever go to actual logs, but rewrite it to make it happy. Fixes tailscale/corp#2695 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Aaron Klotz	9ebb5d4205	ipn, paths: ensure that the state directory for Windows has the correct perms ProgramData has a permissive ACL. For us to safely store machine-wide state information, we must set a more restrictive ACL on our state directory. We set the ACL so that only talescaled's user (ie, LocalSystem) and the Administrators group may access our directory. We must include Administrators to ensure that logs continue to be easily accessible; omitting that group would force users to use special tools to log in interactively as LocalSystem, which is not ideal. (Note that the ACL we apply matches the ACL that was used for LocalSystem's AppData\Local). There are two cases where we need to reset perms: One is during migration from the old location to the new. The second case is for clean installations where we are creating the file store for the first time. Updates #2856 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	3 years ago
Josh Bleecher Snyder	b14db5d943	util/codegen: reorder AssertStructUnchanged args The fully qualified name of the type is thisPkg.tname, so write the args like that too. Suggested-by: Joe Tsai <joetsai@digital-static.net> Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	d5a0a4297e	cmd/cloner: unify switch cases And in the process, fix a bug: The fmt formatting was being applied by writef, not fmt.Sprintf, thus emitting a MISSING string. And there's no guarantee that fmt will be imported in the generated code. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	4bbf5a8636	cmd/cloner: reduce diff noise when changing command Spelling out the command to run for every type means that changing the command makes for a large, repetitive diff. Stop doing that. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Silver Bullet	d8c5d00ecb	cmd/derper: support manual TLS certificate mode (#2793 ) Add a mode control for derp server, and add a "manual" mode to get derp server certificate. Under manual mode, certificate is searched in the directory given by "--cert-dir". Certificate should in PEM format, and use "hostname.{key,crt}" as filename. If no hostname is used, search by the hostname given for listen. Fixes #2794 Signed-off-by: SilverBut <SilverBut@users.noreply.github.com>	3 years ago

Dave Anderson	980acc38ba	types/key: add a special key with custom serialization for control private keys (#2792 ) * Revert "Revert "types/key: add MachinePrivate and MachinePublic."" This reverts commit `61c3b98a24`. Signed-off-by: David Anderson <danderson@tailscale.com> * types/key: add ControlPrivate, with custom serialization.
