All code relating to a caddytls.Config and setting it up from the
Caddyfile is still intact; only the certificate management-related
code was removed into a separate package.
I don't expect this to build in CI successfully; updating dependencies
and vendor is coming next.
I've also removed the ad-hoc, half-baked storage plugins that we need
to finish making first-class Caddy plugins (they were never documented
anyway). The new certmagic package has a much better storage interface,
and we can finally move toward making a new storage plugin type, but
it shouldn't be configurable in the Caddyfile, I think, since it doesn't
make sense for a Caddy instance to use more than one storage config...
We also have the option of eliminating DNS provider plugins and just
shipping all of lego's DNS providers by using a lego package (the
caddytls/setup.go file has a comment describing how) -- but it doubles
Caddy's binary size by 100% from about 19 MB to around 40 MB...!
- Introduce StrictHostMatching mode for sites that require clientauth
- Error if QUIC is enabled whilst TLS clientauth is configured
(Our QUIC implementation does not yet support TLS clientauth, but
maybe it will in the future - fixes#2095)
- Error if one but not all TLS configs for the same hostname have a
different ClientAuth CA pool
* Trim path prefix using EscapedPath()
* clarify comments
* Added Tests for trimPathPrefix
* Ensure path with trailing slash is properly trimmed
* Updated tests to match prepatch behaviour
* Updated tests to match prepatch behaviour
* call parse on url rather than instance
* add additional tests
* return unmodified url if error. Additional tests
(See EULA.) Personally-licensed official Caddy builds cannot remove
this header by configuration. The commercially-licensed builds of Caddy
don't have this header.
* httpserver/all: Clean up and standardize request URL handling
The HTTP server now always creates a context value on the request which
is a copy of the request's URL struct. It should not be modified by
middlewares, but it is safe to get the value out of the request and make
changes to it locally-scoped. Thus, the value in the context always
stores the original request URL information as it was received. Any
rewrites that happen will be to the request's URL field directly.
The HTTP server no longer cleans /sanitizes the request URL. It made too
many strong assumptions and ended up making a lot of middleware more
complicated, including upstream proxying (and fastcgi). To alleviate
this complexity, we no longer change the request URL. Middlewares are
responsible to access the disk safely by using http.Dir or, if not
actually opening files, they can use httpserver.SafePath().
I'm hoping this will address issues with #1624, #1584, #1582, and others.
* staticfiles: Fix test on Windows
@abiosoft: I still can't figure out exactly what this is for. 😅
* Use (potentially) changed URL for browse redirects, as before
* Use filepath.ToSlash, clean up a couple proxy test cases
* Oops, fix variable name
* add support for listener middleware
* add proxyprotocol directive
* make caddy.Listener interface required
* Remove tcpKeepAliveListener wrapper from Serve()
This is now done in the Listen() function, along with other potential middleware.
* Use RequestURI when redirecting to canonical path.
Caddy may trim a request's URL path when it starts with the path that's
associated with the virtual host. This change uses the path from the request's
RequestURI when performing a redirect.
Fix issue #1327.
* Rename redirurl to redirURL.
* Redirect to the full URL.
The scheme and host from the virtual host's site configuration is used
in order to redirect to the full URL.
* Add comment and remove redundant check.
* Store the original URL path in request context.
By storing the original URL path as a value in the request context,
middlewares can access both it and the sanitized path. The default
default FileServer handler will use the original URL on redirects.
* Replace contextKey type with CtxKey.
In addition to moving the CtxKey definition to the caddy package, this
change updates the CtxKey references in the httpserver, fastcgi, and
basicauth packages.
* httpserver: Fix reference to CtxKey
Timeouts are important for mitigating slowloris, yes. But after a number
of complaints and seeing that default timeouts are a sore point of
confusion, we're disabling them now. However, the code that sets
default timeouts remains intact; the defaults are just the zero value.
While Caddy aims to be secure by default, Caddy also aims to serve a
worldwide audience. Even my own internet here in Utah is poor at times,
with bad WiFi signal, causing some connections to take over 10s to
be established. Many use the Internet while commuting on slower
connection speeds. Latency across country borders is another concern.
As such, disabling default timeouts will serve a greater population of
users than enabling them, as slowloris is easy to mitigate and does
not seem to be reported often (I've only seen it once). It's also very
difficult sometimes to distinguish slowloris from genuine slow networks.
That decision is best left to the site owner for now.
* tls: Refactor TLS config innards with a few minor syntax changes
muststaple -> must_staple
"http2 off" -> "alpn" with list of ALPN values
* Fix typo
* Fix QUIC handler
* Inline struct field assignments
* WIP: Implement HTTPS interception detection by Durumeric, et. al.
Special thanks to @FiloSottile for guidance with the custom listener.
* Add {{.IsMITM}} context action and {mitm} placeholder
* Improve MITM detection heuristics for Firefox and Edge
* Add tests for MITM detection heuristics
* Improve Safari heuristics for interception detection
* Read ClientHello during first Read() instead of during Accept()
As far as I can tell, reading the ClientHello during Accept() prevents
new connections from being accepted during the read. Since Read() should
be called in its own goroutine, this keeps Accept() non-blocking.
* Clean up MITM detection handler; make possible to close connection
* Use standard lib cipher suite values when possible
* Improve Edge heuristics and test cases
* Refactor MITM checking logic; add some debug statements for now
* Fix bug in MITM heuristic tests and actual heuristic code
* Fix gofmt
* Remove debug statements; preparing for merge
