Andrew Dunham	e8d2fc7f7f	net/tshttpproxy: log when we're using a proxy Updates #11196 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: Id6334c10f52f4cfbda9f03dc8096ab7a6c54a088	9 months ago
Andrew Dunham	38e4d303a2	net/tshttpproxy: don't proxy through ourselves When running a SOCKS or HTTP proxy, configure the tshttpproxy package to drop those addresses from any HTTP_PROXY or HTTPS_PROXY environment variables. Fixes #7407 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I6cd7cad7a609c639780484bad521c7514841764b	2 years ago
Mihai Parparita	b6908181ff	net/tshttpproxy: more directly use Transport proxy CONNECT hooks GetProxyConnectHeader (golang/go#41048) was upstreamed in Go 1.16 and OnProxyConnectResponse (golang/go#54299) in Go 1.20, thus we no longer need to guard their use by the tailscale_go build tag.

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>	2 years ago
Brad Fitzpatrick	fb392e34b5	net/tshttpproxy: don't ignore env-based HTTP proxies after system lookups fail There was a mechanism in tshttpproxy to note that a Windows proxy lookup failed and to stop hitting it so often. But that turns out to fire a lot (no PAC file configured at all results in a proxy lookup), so after the first proxy lookup, we were enabling the "omg something's wrong, stop looking up proxies" bit for awhile, which was then also preventing the normal Go environment-based proxy lookups from working. This at least fixes environment-based proxies. Plenty of other Windows-specific proxy work remains (using WinHttpGetIEProxyConfigForCurrentUser instead of just PAC files, ignoring certain types of errors, etc), but this should fix the regression reported in #4811.

Brad Fitzpatrick	6a2c6541da	net/tshttpproxy: support HTTP proxy environment credentials on Windows too and some minor style nits. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Christine Dodrill	3e5c3e932c	net/tshttpproxy: support basic auth when available (#1354 ) This allows proxy URLs such as: http://azurediamond:hunter2@192.168.122.154:38274 to be used in order to dial out to control, logs or derp servers.

Brad Fitzpatrick	5bcac4eaac	net/tshttpproxy: add GetProxyForURL negative cache Otherwise when PAC server is down, we log, and each log entry is a new HTTP request (from logtail) and a new GetProxyForURL call, which again logs, non-stop. This is also nicer to the WinHTTP service. Then also hook up link change notifications to the cache to reset it if there's a chance the network might work sooner.	4 years ago

Brad Fitzpatrick	28f9cd06f5	tshttpproxy, controlclient, derphttp, logpolicy: send Negotiate auth to proxies For Windows only, and only when built with Tailscale's Go tree. Updates tailscale/corp#583	4 years ago
Brad Fitzpatrick	f915ab6552	net/tshttpproxy: add start of Kerberos Negotiate auth to proxies on Windows For now only used by a new cmd/tailscale debug --get-url subcommand. Not yet wired up to the places making HTTP requests. Updates tailscale/corp#583	4 years ago
Brad Fitzpatrick	c5eb57f4d6	net/tshttpproxy: new package, support WPAD/PAC proxies on Windows Updates tailscale/corp#553 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
