2020-05-06tls/client auth: verify first certificates in client request (#3344)Karol Będkowski
When client certificate is enabled Caddy check only last certificate from request. When this cert is not in list of trusted leaf certificates, connection is rejected. According to RFC TLS1.x the sender's certificate must come first in the list. Each following certificate must directly certify the one preceding it. This patch fix this problem - first certificate is checked instead of last.
2020-05-05httpcaddyfile: Only append TLS conn policy if it's non-empty (#3319)Matt Holt
This can lead to nicer, smaller JSON output for Caddyfiles like this: a { tls internal } b { tls foo@bar.com } i.e. where the tls directive only configures automation policies, and is merely meant to enable TLS on a server block (if it wasn't implied). This helps keeps implicit config implicit. Needs a little more testing to ensure it doesn't break anything important.

2020-04-01caddytls: Refactor certificate selection policies (close #1575)Matthew Holt
Certificate selection used to be a module, but this seems unnecessary, especially since the built-in CustomSelectionPolicy allows quite complex selection logic on a number of fields in certs. If we need to extend that logic, we can, but I don't think there are SO many possibilities that we need modules. This update also allows certificate selection to choose between multiple matching certs based on client compatibility and makes a number of other improvements in the default cert selection logic, both here and in the latest CertMagic. The hardest part of this was the conn policy consolidation logic (Caddyfile only, of course). We have to merge connection policies that we can easily combine, because if two certs are manually loaded in a Caddyfile site block, that produces two connection policies, and each cert is tagged with a different tag, meaning only the first would ever be selected. So given the same matchers, we can merge the two, but this required improving the Tag selection logic to support multiple tags to choose from, hence "tags" changed to "any_tag" or "all_tags" (but we use any_tag in our Caddyfile logic). Combining conn policies with conflicting settings is impossible, so that should return an error if two policies with the exact same matchers have non-empty settings that are not the same (the one exception being any_tag which we can merge because the logic for them is to OR them). It was a bit complicated. It seems to work in numerous tests I've conducted, but we'll see how it pans out in the release candidates.
2020-04-01caddytls: Update cipher suite names and curve namesMatthew Holt

2020-03-06Refactor for CertMagic v0.10; prepare for PKI appMatthew Holt
This is a breaking change primarily in two areas: - Storage paths for certificates have changed - Slight changes to JSON config parameters Huge improvements in this commit, to be detailed more in the release notes. The upcoming PKI app will be powered by Smallstep libraries.

2019-12-28http: Enable TLS for servers listening only on HTTPS portMatthew Holt
It seems silly to have to add a single, empty TLS connection policy to a server to enable TLS when it's only listening on the HTTPS port. We now do this for the user as part of automatic HTTPS (thus, it can be disabled / overridden). See https://caddy.community/t/v2-catch-all-server-with-automatic-tls/6692/2?u=matt
2019-12-10v2: Module documentation; refactor LoadModule(); new caddy struct tags (#2924)Matt Holt
This commit goes a long way toward making automated documentation of Caddy config and Caddy modules possible. It's a broad, sweeping change, but mostly internal. It allows us to automatically generate docs for all Caddy modules (including future third-party ones) and make them viewable on a web page; it also doubles as godoc comments. As such, this commit makes significant progress in migrating the docs from our temporary wiki page toward our new website which is still under construction. With this change, all host modules will use ctx.LoadModule() and pass in both the struct pointer and the field name as a string. This allows the reflect package to read the struct tag from that field so that it can get the necessary information like the module namespace and the inline key. This has the nice side-effect of unifying the code and documentation. It also simplifies module loading, and handles several variations on field types for raw module fields (i.e. variations on json.RawMessage, such as arrays and maps). I also renamed ModuleInfo.Name -> ModuleInfo.ID, to make it clear that the ID is the "full name" which includes both the module namespace and the name. This clarity is helpful when describing module hierarchy. As of this change, Caddy modules are no longer an experimental design. I think the architecture is good enough to go forward.
2019-09-30tls: Change struct fields to pointers, add nil checks; rate.Burst updateMatthew Holt
Making them pointers makes for cleaner JSON when adapting configs, if the struct is empty now it will be omitted entirely. The x/time/rate package was updated to support changing the burst, so we've incorporated that here and removed a TODO.

2019-08-09Implement config adapters and beginning of Caddyfile adapterMatthew Holt
Along with several other changes, such as renaming caddyhttp.ServerRoute to caddyhttp.Route, exporting some types that were not exported before, and tweaking the caddytls TLS values to be more consistent. Notably, we also now disable automatic cert management for names which already have a cert (manually) loaded into the cache. These names no longer need to be specified in the "skip_certificates" field of the automatic HTTPS config, because they will be skipped automatically.
