Andrew Lytvynov	7c04846eac	tsweb: relax CSP for debug handlers (#8649) ... Allow inline CSS for debug handlers to make prototyping easier. These are generally not accessible to the public and the small risk of CSS injection via user content seems acceptable. Also allow form submissions on the same domain, instead of banning all forms. An example of such form is http://webhooks.corp.ts.net:6359/debug/private-nodes/ Updates #3576 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	11 months ago
Andrew Lytvynov	96d7af3469	cmd/derper,tsweb: consistently add HTTP security headers (#8579) ... Add a few helper functions in tsweb to add common security headers to handlers. Use those functions for all non-tailscaled-facing endpoints in derper. Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	11 months ago
Anton Tolchanov	8546ff98fb	tsweb: move varz handler(s) into separate modules ... This splits Prometheus metric handlers exposed by tsweb into two modules: - `varz.Handler` exposes Prometheus metrics generated by our expvar converter; - `promvarz.Handler` combines our expvar-converted metrics and native Prometheus metrics. By default, tsweb will use the promvarz handler, however users can keep using only the expvar converter. Specifically, `tailscaled` now uses `varz.Handler` explicitly, which avoids a dependency on the (heavyweight) Prometheus client.

Anton Tolchanov	11e6247d2a	tsweb: expose native Prometheus metrics in /debug/varz ... The handler will expose built-in process and Go metrics by default, which currently duplicate some of the expvar-proxied metrics (`goroutines` vs `go_goroutines`, `memstats` vs `go_memstats`), but as long as their names are different, Prometheus server will just scrape both. This will change /debug/varz behaviour for most tsweb binaries, but notably not for control, which configures a `tsweb.VarzHandler` [explicitly](a5b5d5167f/cmd/tailcontrol/tailcontrol.go (L779)) Updates https://github.com/tailscale/corp/issues/10205 Signed-off-by: Anton Tolchanov <anton@tailscale.com>	1 year ago
David Anderson	8b2ae47c31	version: unexport all vars, turn Short/Long into funcs ... The other formerly exported values aren't used outside the package, so just unexport them. Signed-off-by: David Anderson <danderson@tailscale.com>	1 year ago
Will Norris	71029cea2d	all: update copyright and license headers ... This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Josh Bleecher Snyder	0868329936	all: use any instead of interface{} ... My favorite part of generics. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	2 years ago
Brad Fitzpatrick	722942dd46	tsweb: restore CPU profiling handler ... It was accidentally deleted in the earlier 0022c3d2e (#2143) refactor. Lock it in with a test. Fixes tailscale/corp#2503 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
