Bring consistency to config options The configuration options that exist in bmcweb are an amalgimation of CROW options, CMAKE options using #define, pre-bmcweb ifdef mechanisms and meson options using a config file. This history has led to a lot of different ways to configure code in the codebase itself, which has led to problems, and issues in consistency. ifdef options do no compile time checking of code not within the branch. This is good when you have optional dependencies, but not great when you're trying to ensure both options compile. This commit moves all internal configuration options to: 1. A namespace called bmcweb 2. A naming scheme matching the meson option. hyphens are replaced with underscores, and the option is uppercased. This consistent transform allows matching up option keys with their code counterparts, without naming changes. 3. All options are bool true = enabled, and any options with _ENABLED or _DISABLED postfixes have those postfixes removed. (note, there are still some options with disable in the name, those are left as-is) 4. All options are now constexpr booleans, without an explicit compare. To accomplish this, unfortunately an option list in config/meson.build is required, given that meson doesn't provide a way to dump all options, as is a manual entry in bmcweb_config.h.in, in addition to the meson_options. This obsoletes the map in the main meson.build, which helps some of the complexity. Now that we've done this, we have some rules that will be documented. 1. Runtime behavior changes should be added as a constexpr bool to bmcweb_config.h 2. Options that require optionally pulling in a dependency shall use an ifdef, defined in the primary meson.build. (note, there are no options that currently meet this class, but it's included for completeness.) Note, that this consolidation means that at configure time, all options are printed. This is a good thing and allows direct comparison of configs in log files. Tested: Code compiles Server boots, and shows options configured in the default build. (HTTPS, log level, etc) Change-Id: I94e79a56bcdc01755036e4e7278c7e69e25809ce Signed-off-by: Ed Tanous <ed@tanous.net>
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 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
.
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.
