2023-07-11caddytls: Reuse certificate cache through reloads (#5623)Matt Holt
* caddytls: Don't purge cert cache on config reload * Update CertMagic This actually avoids reloading managed certs from storage when already in the cache, d'oh. * Fix bug; re-implement HasCertificateForSubject * Update go.mod: CertMagic tag

2023-02-06admin: Add `CADDY_ADMIN` env var to override the default (#5332)Francis Lavoie
2022-11-23admin: set certmagic cache logger (#5173)bit
same way it is set in modules/caddytls/tls.go
2022-11-23admin: fix certificate renewal for admin (#5169)bit
certmagic.New takes a template and returns pointer to the new config. GetConfigForCert later must return a pointer to the new config not the template. fixes #5162
2022-09-29admin: Use replacer on listen addresses (#5071)Cory Cooper
* admin: use replacer on listen address * admin: consolidate replacer logic
2022-09-28core: Refactor and improve listener logic (#5089)Matt Holt
* core: Refactor, improve listener logic Deprecate: - caddy.Listen - caddy.ListenTimeout - caddy.ListenPacket Prefer caddy.NetworkAddress.Listen() instead. Change: - caddy.ListenQUIC (hopefully to remove later) - caddy.ListenerFunc signature (add context and ListenConfig) - Don't emit Alt-Svc header advertising h3 over HTTP/3 - Use quic.ListenEarly instead of quic.ListenEarlyAddr; this gives us more flexibility (e.g. possibility of HTTP/3 over UDS) but also introduces a new issue: https://github.com/lucas-clemente/quic-go/issues/3560#issuecomment-1258959608 - Unlink unix socket before and after use * Appease the linter * Keep ListenAll
2022-09-02notify: Don't send ready after error (fix #5003)Matthew Holt
Also simplify the notify package quite a bit. Also move stop notification into better place. Add ability to send status or error.

2022-03-02pki: Implement API endpoints for certs and `caddy trust` (#4443)Francis Lavoie
* admin: Implement /pki/certificates/<id> API * pki: Lower "skip_install_trust" log level to INFO See https://github.com/caddyserver/caddy/issues/4058#issuecomment-976132935 It's not necessary to warn about this, because this was an option explicitly configured by the user. Still useful to log, but we don't need to be so loud about it. * cmd: Export functions needed for PKI app, return API response to caller * pki: Rewrite `caddy trust` command to use new admin endpoint instead * pki: Rewrite `caddy untrust` command to support using admin endpoint * Refactor cmd and pki packages for determining admin API endpoint

2021-04-05notify: Send all sd_notify signals from main caddy process (#4060)Carl George
Initial sd_notify support was added in #3963, but that sent signals from both cmdRun and cmdReload. This approach has two drawbacks: - Reloads initiated via the API do not send signals. - The signals are sent from different processes, which requires the `NotifyAccess=exec` directive in the unit file. This change moves the NotifyReloading and NotifyReadiness invocations to Load, which address both of those drawbacks. It also adds a complimentary NotifyStopping method which is invoked from handleStop. All the notify methods are defined in a notify package to avoid an import loop.
2021-01-27admin: Identity management, remote admin, config loaders (#3994)Matt Holt
This commits dds 3 separate, but very related features: 1. Automated server identity management How do you know you're connecting to the server you think you are? How do you know the server connecting to you is the server instance you think it is? Mutually-authenticated TLS (mTLS) answers both of these questions. Using TLS to authenticate requires a public/private key pair (and the peer must trust the certificate you present to it). Fortunately, Caddy is really good at managing certificates by now. We tap into that power to make it possible for Caddy to obtain and renew its own identity credentials, or in other words, a certificate that can be used for both server verification when clients connect to it, and client verification when it connects to other servers. Its associated private key is essentially its identity, and TLS takes care of possession proofs. This configuration is simply a list of identifiers and an optional list of custom certificate issuers. Identifiers are things like IP addresses or DNS names that can be used to access the Caddy instance. The default issuers are ZeroSSL and Let's Encrypt, but these are public CAs, so they won't issue certs for private identifiers. Caddy will simply manage credentials for these, which other parts of Caddy can use, for example: remote administration or dynamic config loading (described below). 2. Remote administration over secure connection This feature adds generic remote admin functionality that is safe to expose on a public interface. - The "remote" (or "secure") endpoint is optional. It does not affect the standard/local/plaintext endpoint. - It's the same as the [API endpoint on localhost:2019](https://caddyserver.com/docs/api), but over TLS. - TLS cannot be disabled on this endpoint. - TLS mutual auth is required, and cannot be disabled. - The server's certificate _must_ be obtained and renewed via automated means, such as ACME. It cannot be manually loaded. - The TLS server takes care of verifying the client. - The admin handler takes care of application-layer permissions (methods and paths that each client is allowed to use).\ - Sensible defaults are still WIP. - Config fields subject to change/renaming. 3. Dyanmic config loading at startup Since this feature was planned in tandem with remote admin, and depends on its changes, I am combining them into one PR. Dynamic config loading is where you tell Caddy how to load its config, and then it loads and runs that. First, it will load the config you give it (and persist that so it can be optionally resumed later). Then, it will try pulling its _actual_ config using the module you've specified (dynamically loaded configs are _not_ persisted to storage, since resuming them doesn't make sense). This PR comes with a standard config loader module called `caddy.config_loaders.http`. Caddyfile config for all of this can probably be added later. COMMITS: * admin: Secure socket for remote management Functional, but still WIP. Optional secure socket for the admin endpoint is designed for remote management, i.e. to be exposed on a public port. It enforces TLS mutual authentication which cannot be disabled. The default port for this is :2021. The server certificate cannot be specified manually, it MUST be obtained from a certificate issuer (i.e. ACME). More polish and sensible defaults are still in development. Also cleaned up and consolidated the code related to quitting the process. * Happy lint * Implement dynamic config loading; HTTP config loader module This allows Caddy to load a dynamic config when it starts. Dynamically-loaded configs are intentionally not persisted to storage. Includes an implementation of the standard config loader, HTTPLoader. Can be used to download configs over HTTP(S). * Refactor and cleanup; prevent recursive config pulls Identity management is now separated from remote administration. There is no need to enable remote administration if all you want is identity management, but you will need to configure identity management if you want remote administration. * Fix lint warnings * Rename identities->identifiers for consistency
