Generate Redfish enums from schemas OpenBMC tends to have a significant problem in doing the appropriate lookups from the schema files, and many bugs have been injected by users picking a bad enum, or mistyping the casing of an enum value. At the same time, nlohmann::json has recently added first class support for enums, https://json.nlohmann.me/features/enum_conversion/ This commit attempts to build a set of redfish includes file with all the available Redfish enums in an easy to use enum class. This makes it very clear which enums are supported by the schemas we produce, and adds very little to no extra boilerplate on the human-written code we produced previously. Note, in the generated enum class, because of our use of the clang-tidy check for macros, the clang-tidy check needs an exception for these macros that don't technically follow the coding standard. This seems like a reasonable compromise, and in this case, given that nlohmann doesn't support a non-macro version of this. One question that arises is what this does to the binary size.... Under the current compiler optimizations, and with the current best practices, it leads to an overall increase in binary size of ~1200 bytes for the enum machinery, then approximately 200 bytes for every call site we switch over. We should decide if this nominal increase is reasonable. Tested: Redfish protocol validator runs with same number of failures as previously. Redfish Service Validator passes (one unrelated qemu-specific exception) Signed-off-by: Ed Tanous <edtanous@google.com> Change-Id: I7c7ee4db0823f7c57ecaa59620b280b53a46e2c1
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 by default is compiled with runtime logging disabled, as a performance consideration. To enable it in a standalone build, add the
-Dlogging='enabled'
option to your configure flags. If building within Yocto, add the following to your local.conf.
EXTRA_OEMESON:pn-bmcweb:append = "-Dbmcweb-logging='enabled'"
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.
