http_client: fix for broken connection http_client is not handling connection termination by server due to keep alive timeout. At present client is not aware of connection termination from server. So whenever next redfish is event ready to be sent, the client will try send/receives data over broken connection. After failed operation the client will try to restart the connection by closing the current connection. Problems: 1) Restart is not attempted on all failure paths. Eg: stream_truncated error was ignored, which usually happens when try to read from broken connection, due to which retry is never performed. 2) Ssl shutdown over broken connection often fails to call the shutdown callback 3) ssl session was reused for new connection attempt. Which is wrong Solution: This patch will try to reattempt the connection in all failure cases. It uses new socket object and new ssl session for the retries Tested by: Test normal event flow between redfish-event clients and the BMC Test failure event flow between redfish-event clients and the BMC Tested the bad path by keeping the setup idle for 3 hours on the above two setups. Verified the events flow after this idle time Change-Id: I3d725b9d77bea22e2e8860e01ee0dfc971789008 Signed-off-by: Abhilash Raju <abhilash.kollam@gmail.com> 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.
