2021-06-14Expand and clarify security policyMatthew Holt
While the Caddy project has had very few valid security bug reports over the years, we have a low signal-to-noise ratio with them (lots of invalid reports). Most are out of scope, and it can take too much valuable time for us to determine that. We would prefer researchers do this first. Hopefully these paragraphs spell out much more clearly what we do and don't accept.
2021-06-14Revert "fileserver: Redirect within the original URL (#4179)"Matthew Holt
This reverts commit f9b54454a19e2b070159ce8d2af76d819658244e. /cc @diamondburned (see #4205)
2021-06-12go.mod: Use CertMagic v0.14.0 (fix #4191)Matt Holt
* Force auto-renew for OCSP revoked status (maybe) (fix #4191) * Use latest commit * go.mod: Use CertMagic v0.14.0 (fix #4191) Correctly replaces revoked certificates
2021-06-09httpcaddyfile: Don't add HTTP hosts to TLS APs (fix #4176 and fix #4198)Matthew Holt
In the Caddyfile, hosts specified for HTTP sockets (either scheme is "http" or it is on the HTTP port) should not be used as subjects in TLS automation policies (APs).
2021-06-08httpcaddyfile: Add `preferred_chains` global option and issuer subdirective ↵Klooven
(#4192) * Added preferred_chains option to Caddyfile * Caddyfile adapt tests for preferred_chains
2021-06-07fileserver: Fix browse not redirecting query parameters (#4196)diamondburned
This commit is a follow up to PR #4179 that introduced a bug where browse redirections to the right URL would not preserve query parameters.
2021-06-07caddytls: Add Caddyfile support for `propagation_timeout` (#4178)Peter Magnusson
* add propagation_timeout to UnmarshalCaddyfile - Closes #4177 * added caddyfile_adapt test
2021-06-07fileserver: Redirect within the original URL (#4179)diamondburned
This commit changes the file_server directive to redirect using the original request's URL instead of the possibly trimmed URL. This should make file_server work with handle_path. This fix is taken from mholt's comment in https://caddy.community/t/file-servers-on-different-paths-not-working/11698/11.

Ubuntu's package updater doesn't show the name of the package, so just adding "Caddy" to the description helps a lot
2021-05-19logging: Implement dial timeout for net writer (fix #4083) (#4172)Matt Holt
* logging: Implement dial timeout for net writer (fix #4083) * Limit how often redials are attempted This should cause dial blocking to occur only once every 10 seconds at most, but it also means the logger connection might be down for up to 10 seconds after it comes back online; oh well. We shouldn't block for DialTimeout at every single log emission. * Clarify offline behavior

2021-05-19admin: Reinstate internal redirect for /id/ requestsMatthew Holt
Fix regression from ab80ff4fd2911afc394b9dbceeb9f71c7a0b7ec1 (probably a mistake when rebasing) See https://caddy.community/t/id-selector-is-not-working-after-upgrade-to-2-4-0/12513?u=matt
2021-05-12caddyfile: Add parse error on site address with trailing `{` (#4163)Francis Lavoie
* caddyfile: Add parse error on site address in `{` This is an incredibly common mistake made by users, so we should catch it earlier in the parser and give a more friendly message. Often it ends up adapting but with mistakes, or erroring out later due to other site addresses being read as directives. There's not really ever a situation where a lone '{' is valid at the end of a site address (but I suppose there are edgecases where the user wants to use a path matcher where it ends specifically in `{`, but... why?), so this should be fine. * Update caddyconfig/caddyfile/parse.go
2021-05-12reverseproxy: Set the headers in the replacer before `handle_response` (#4165)Francis Lavoie
Turns out this was an oversight, we assumed we could use `{http.response.header.*}` but that doesn't work because those are grabbed from the response writer, and we haven't copied any headers into the response writer yet. So the fix is to set all the response headers into the replacer at a new namespace before running the handlers. This adds the `{http.reverse_proxy.header.*}` replacer. See https://caddy.community/t/empty-http-response-header-x-accel-redirect/12447
2021-05-12ci: Run CI on PRs targeting minor version branches (#4164)Francis Lavoie
We decided that we'll use branches like `2.4` as the target for any changes that we might want to release in a `2.4.x` version like `2.4.1`, so that we can continue to merge changes targeting the next minor release (e.g. `2.5.0`) on master. Our CI config wasn't set up for this to work properly though, since it was only running checks on PRs targeting master. This should fix it. I couldn't find a way to do a pattern to only match digits for the branch names from Github's docs, it just looks like a pretty generic glob syntax. But this should do until we get to 3.0

2021-05-10caddyfile: Fix `caddy fmt` nesting not decrementing (#4157)Matthew Penner
* caddyfile(formatter): fix nesting not decrementing This is an extremely weird edge-case where if you had a environment variable {} on one line, a comment on the next line, and the closing of the block on the following line; the rest of the Caddyfile would be indented further than it should've been. ref; https://github.com/matthewpi/vscode-caddyfile-support/issues/13 * run gofmt * fmt: better way of handling edge case
2021-05-10encode: Drop `prefer` from Caddyfile (#4156)Francis Lavoie
Followup to #4150, #4151 /cc @ueffel @polarathene After a bit of discussion with @mholt, we decided to remove `prefer` as a subdirective and just go with using the order implicitly always. Simpler config, simpler docs, etc. Effectively changes 7776471 and reverts a small part of f35a7fa.

2021-05-05caddyhttp: Fix fallback for the error handler chain (#4131)Francis Lavoie
* caddyhttp: Fix fallback for the error handler chain The fix I went with in the end (after realizing some mistaken assumptions in #4131) is to just make the routes fall back to errorEmptyHandler instead of the non-error empty handler, if Terminal is true, making the routes error-aware. Ultimately this was probably just an oversight when errors was implemented at some point in the early betas of v2. See https://caddy.community/t/problem-with-basicauth-handle-errors/12243/9 for context. * Revert "caddyhttp: Fix fallback for the error handler chain" This reverts commit 95b6ac44a6122d3ca5513a13bbc723cd5f4785f8. * caddyhttp: Fix via `routes.go`

2021-05-04fileserver: Fix `file` matcher with empty `try_files` (#4147)Francis Lavoie
* fileserver: Fix `file` matcher with empty `try_files` Fixes https://github.com/caddyserver/caddy/issues/4146 If `TryFiles` is empty, we fill it with `r.URL.Path`. In this case, this is `/`. Then later, in `prepareFilePath()`, we run the replacer (which turns `{path}` into `/` at that point) but `file` remains the original value (and the placeholder is still the placeholder there). So then `strings.HasSuffix(file, "/")` will be `false` for the placeholder, but `true` for the empty `TryFiles` codepath, because `file` was `/` due to being set to the actual request value beforehand. This means that `suffix` becomes `//` in that case, so after `sanitizedPathJoin`, it becomes `./`, so `strictFileExists`'s `strings.HasSuffix(file, separator)` codepath will return true. I think we should change the `m.TryFiles == nil` codepath to `m.TryFiles = []string{"{http.request.uri.path}"}` for consistency. (And maybe consider hoisting this to `Provision` cause there's no point doing this on every request). I don't think this "optimization" of directly using `r.URL.Path` is so valuable, cause it causes this edgecase with directories. * Update modules/caddyhttp/fileserver/matcher.go Co-authored-by: Matt Holt <mholt@users.noreply.github.com> Co-authored-by: Matt Holt <mholt@users.noreply.github.com>

* caddyfile: Fix `import` replacing unrelated placeholders See https://caddy.community/t/snippet-issue-works-outside-snippet/12231 So it turns out that `NewReplacer()` gives a replacer with some global defaults (like `{env.*}` and some system and time placeholders), which is not ideal when running `import` because we just want to replace `{args.*}` only, and nothing else. * caddyfile: Add test
2021-04-21caddytls: Add `load_storage` module (#4055)Francis Lavoie
An idea that came up in https://caddy.community/t/save-internally-issued-wildcard-certificate-in-consul/11740, this a simple module that might be useful for anyone who uses storage modules that aren't filesystem, to let them load certs/keys externally issued for use by Caddy. Bit goofy, since we need to fetch the certmagic.Storage during provisioning, it needs a wrapping struct instead of just being an array like `load_files`. Future work might involve adding Caddyfile support via a subdirective of the `tls` directive maybe?
