* caddyhttp: Reject 0-RTT early data in IP matchers and set Early-Data header when proxying
See RFC 8470: https://httpwg.org/specs/rfc8470.html
Thanks to Michael Wedl (@MWedl) at the University of Applied Sciences St. Poelten for reporting this.
* Don't return value for {remote} placeholder in early data
* Add Caddyfile support
101d3e7 introduced a configuration option to set the log file mode.
This option was not taken into account if the file already exists,
making users having to delete their logs to have new logs created
with the right mode.
* Split `run` into a public `BuildContext` and a private part
`BuildContext` can be used to set up a caddy context from a config, but not start any listeners
or active components: The returned context has the configured apps provisioned, but otherwise is
inert.
This is EXPERIMENTAL: Minimally it's missing documentation and the example for how this can be
used to run unit tests.
* Use the config from the context
The config passed into `BuildContext` can be nil, in which case `BuildContext` will just make one
up that works. In either case that will end up in the finished context.
* Rename `BuildContext` to `ProvisionContext` to better match the function
* Hide the `replaceAdminServer` parts
The admin server is a global thing, and in the envisioned use case for `ProvisionContext`
shouldn't actually exist. Hide this detail in a private `provisionContext` instead, and
only expose it publicly with `replaceAdminServer` set to `false`.
This should reduce foot-shooting potential further; in addition the documentation comment
now clearly spells out that the exact interface and implementation details of `ProvisionContext`
are experimental and subject to change.

SanitizePathJoin protects against directory traversal attacks by
checking for requests whose URL path look like they are trying to
request something other than a local file, and returns the root
directory in those cases.
The method is also careful to ensure that requests which contain a
trailing slash include a trailing slash in the returned value. However,
for requests that contain only a slash (requests for the root path), the
IsLocal check returns early before the matching trailing slash is
re-added.
This change updates SanitizePathJoin to only perform the
filepath.IsLocal check if the cleaned request URL path is non-empty.
---
This change also updates the existing SanitizePathJoin tests to use
filepath.FromSlash rather than filepath.Join. This makes the expected
value a little easier to read, but also has the advantage of not being
processed by filepath.Clean like filepath.Join is. This means that the
exact expect value will be compared, not the result of first cleaning
it.
Fixes#6352
Certificate automation has permission modules that are designed to
prevent inappropriate issuance of unbounded or wildcard certificates.
When an explicit cert manager is used, no additional permission should
be necessary. For example, this should be a valid caddyfile:
https:// {
tls {
get_certificate tailscale
}
respond OK
}
This is accomplished when provisioning an AutomationPolicy by tracking
whether there were explicit managers configured directly on the policy
(in the ManagersRaw field). Only when a number of potentially unsafe
conditions are present AND no explicit cert managers are configured is
an error returned.
The problem arises from the fact that ctx.LoadModule deletes the raw
bytes after loading in order to save memory. The first time an
AutomationPolicy is provisioned, the ManagersRaw field is populated, and
everything is fine.
An AutomationPolicy with no subjects is treated as a special "catch-all"
policy. App.createAutomationPolicies ensures that this catch-all policy
has an ACME issuer, and then calls its Provision method again because it
may have changed. This second time Provision is called, ManagesRaw is no
longer populated, and the permission check fails because it appears as
though the policy has no explicit managers.
Address this by storing a new boolean on AutomationPolicy recording
whether it had explicit cert managers configured on it.
Also fix an inverted boolean check on this value when setting
failClosed.
