Only parse to the depth requested There are cases in aggregation where an expand parameter might get forwarded to a client. Because our previous expand algorithm assumed that any endpoint within bmcweb would only produce "depth=1" responses, it was reasonable to assume that the pre-response could not contain expanded content. Aggregated resources can't make that assumption. This commit attempts to pass through depth through the request, to ensure that we only expand the level that the user requested, and not any level returned by the request. This is done by using the existence of the resource identifer "@odata.id" to indicate each level in an expanded response. This should be fine since the Redfish spec requires that property to exist. Added unit tests to cover aggregation scenarios. Modified existing $expand tests to comply with the resource identifier dependency. Tested: New unit tests pass Queried '/redfish/v1/Systems?$expand=.($levels=2)' on an aggregated system whose satellite BMC supported $expand. The overall response was correctly expanded for both resources on the aggregating BMC as well as on the satellite BMC. Expanding the satellite resources did not require sending multiple queries to the satellite.

This component attempts to be a "do everything" embedded webserver for OpenBMC.
The webserver implements a few distinct interfaces:
bmcweb at a protocol level supports http and https. TLS is supported through OpenSSL.
Bmcweb supports multiple authentication protocols:
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.
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.
bmcweb is configured per the meson build files. Available options are documented in meson_options.txt
meson 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
.
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.
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.
bmcweb is capable of aggregating resources from satellite BMCs. Refer to AGGREGATION.md for more information on how to enable and use this feature.
