IndicatorLED: Add compile option for deprecated property

The IndicatorLED property has been deprecated by Redfish since September
2020. The Redfish Service Validator reports a WARNING for this property:

```
WARNING - IndicatorLED: The given property is deprecated: This property has been deprecated in favor of the `LocationIndicatorActive` property.
```

The LocationIndicatorActive property is now implemented in bmcweb in
all places where IndicatorLED was implemented. So a new meson option
(redfish-allow-deprecated-indicatorled) is being added to control
whether this property is part of get or patch requests. The option is
disabled by default with plans to remove the option by March 2026.

Tested:
 - Built with option enabled and confirmed IndicatorLED still part of
   Redfish responses and can be patched.
 - Built with option disabled and confirmed Redfish Service Validator no
   longer reports the warning.
 - Built with option disabled and confirmed IndicatorLED no longer part
   of Redfish responses and patch fails appropriately.

OpenBMC webserver

This component attempts to be a "do everything" embedded webserver for OpenBMC.

Features

The webserver implements a few distinct interfaces:

  • DBus event websocket. Allows registering on changes to specific dbus paths, properties, and will send an event from the websocket if those filters match.
  • OpenBMC DBus REST api. Allows direct, low interference, high fidelity access to dbus and the objects it represents.
  • Serial: A serial websocket for interacting with the host serial console through websockets.
  • Redfish: A protocol compliant, DBus to Redfish translator.
  • KVM: A websocket based implementation of the RFB (VNC) frame buffer protocol intended to mate to webui-vue to provide a complete KVM implementation.

Protocols

bmcweb at a protocol level supports http and https. TLS is supported through OpenSSL. Http1 and http2 are supported using ALPN registration for TLS connections and h2c upgrade header for http connections.

AuthX

Authentication

Bmcweb supports multiple authentication protocols:

  • Basic authentication per RFC7617
  • Cookie based authentication for authenticating against webui-vue
  • Mutual TLS authentication based on OpenSSL
  • Session authentication through webui-vue
  • XToken based authentication conformant to Redfish DSP0266

Each of these types of authentication is able to be enabled or disabled both via runtime policy changes (through the relevant Redfish APIs) or via configure time options. All authentication mechanisms supporting username/password are routed to libpam, to allow for customization in authentication implementations.

Authorization

All authorization in bmcweb is determined at routing time, and per route, and conform to the Redfish PrivilegeRegistry.

*Note: Non-Redfish functions are mapped to the closest equivalent Redfish privilege level.

Configuration

bmcweb is configured per the meson build files. Available options are documented in meson_options.txt

Compile bmcweb with default options

meson setup builddir
ninja -C builddir

If any of the dependencies are not found on the host system during configuration, meson will automatically download them via its wrap dependencies mentioned in bmcweb/subprojects.

Use of persistent data

bmcweb relies on some on-system data for storage of persistent data that is internal to the process. Details on the exact data stored and when it is read/written can seen from the persistent_data namespace.

TLS certificate generation

When SSL support is enabled and a usable certificate is not found, bmcweb will generate a self-signed a certificate before launching the server. Please see the bmcweb source code for details on the parameters this certificate is built with.

Compression

bmcweb supports various forms of http compression, including zstd and gzip. Client headers are observed to determine whether compressed payloads are supported.

Redfish Aggregation

bmcweb is capable of aggregating resources from satellite BMCs. Refer to AGGREGATION.md for more information on how to enable and use this feature.
