2022-02-17caddytls: Support external certificate Managers (like Tailscale) (#4541)Matt Holt
Huge thank-you to Tailscale (https://tailscale.com) for making this change possible! This is a great feature for Caddy and Tailscale is a great fit for a standard implementation. * caddytls: GetCertificate modules; Tailscale * Caddyfile support for get_certificate Also fix AP provisioning in case of empty subject list (persist loaded module on struct, much like Issuers, to surive reprovisioning). And implement start of HTTP cert getter, still WIP. * Update modules/caddytls/automation.go Co-authored-by: Francis Lavoie <lavofr@gmail.com> * Use tsclient package, check status for name * Implement HTTP cert getter And use reuse CertMagic's PEM functions for private keys. * Remove cache option from Tailscale getter Tailscale does its own caching and we don't need the added complexity... for now, at least. * Several updates - Option to disable cert automation in auto HTTPS - Support multiple cert managers - Remove cache feature from cert manager modules - Minor improvements to auto HTTPS logging * Run go mod tidy * Try to get certificates from Tailscale implicitly Only for domains ending in .ts.net. I think this is really cool! Co-authored-by: Francis Lavoie <lavofr@gmail.com>

2022-01-24caddyhttp: Fix test when /tmp/etc already exists (#4544)Kevin Daudt
The TestFileListing test in tplcontext_test has one test that verifies if directory traversal is not happening. The context root is set to '/tmp' and then it tries to open '../../../../../etc', which gets normalized to '/tmp/etc'. The test then expects an error to be returned, assuming that '/tmp/etc' does not exist on the system. When it does exist, it results in a test failure: ``` --- FAIL: TestFileListing (0.00s) tplcontext_test.go:422: Test 4: Expected error but had none FAIL FAIL github.com/caddyserver/caddy/v2/modules/caddyhttp/templates 0.042s ``` Instead of using '/tmp' as root, use a dedicated directory created with `os.MkdirTemp()` instead. That way, we know that the directory is empty.

2022-01-18httpcaddyfile: Fix incorrect handling of IPv6 bind addresses (#4532)Francis Lavoie
The `net.JoinHostPort()` function has some naiive logic for handling IPv6, it just checks if the host part has a `:` and if so it wraps the host part with `[ ]` but this causes our network type prefix to get wrapped as well, which is invalid for `caddy.NetworkAddress`. Instead, we can just concatenate the host and port manually here to avoid this side-effect.

Potential fix for #4017 although the consensus is unclear. Made change to return status code 421 instead of 403 when StrictSNIHost matching is on.

2022-01-10core: Simplify shared listeners, fix deadline bugMatthew Holt
When this listener code was first written, UsagePool didn't exist. We can simplify much of the wrapped listener logic by utilizing UsagePool. This also fixes a bug where new servers were able to clear deadlines set by old servers, even if the old server didn't get booted out of its Accept() call yet. And with the deadline cleared, they never would. (Sometimes. Based on reports and difficulty of reproducing the bug, this behavior was extremely rare.) I don't know why that happened exactly, maybe some polling mechanism in the kernel and if the timings worked out just wrong it would expose the bug. Anyway, now we ensure that only the closer that set the deadline is the same one that clears it, ensuring that old servers always return out of Accept(), because the deadline doesn't get cleared until they do. Of course, all this hinges on the hope that my suspicions in the middle of the night are correct and that kernels work the way I think they do in my head. Also minor enhancement to UsagePool where if a value errors upon construction (a very real possibility with listeners), it is removed from the pool. Not 100% sure the sync logic is correct there, or maybe we don't have to even put it in the pool until after construction, but it's subtle either way and I think this is safe... right?

2021-12-30caddyhttp: Fix `MatchPath` sanitizing (#4499)Francis Lavoie
This is a followup to #4407, in response to a report on the forums: https://caddy.community/t/php-fastcgi-phishing-redirection/14542 Turns out that doing `TrimRight` to remove trailing dots, _before_ cleaning the path, will cause double-dots at the end of the path to not be cleaned away as they should. We should instead remove the dots _after_ cleaning.
