sys/dev/mps/mps_user.c Fix uninitialized memory reference in mps_read_config_page. It was referencing a field (params->hdr.Ext.ExtPageType) that would only be set when reading an Extended config page. The symptom was that MPSIO_READ_CFG_PAGE ioctls would randomly fail with MPI2_IOCSTATUS_CONFIG_INVALID_PAGE errors. The solution is to determine whether an extended or an ordinary config page is requested by looking at the PageType field, which should be available regardless. Similarly, mps_user_read_extcfg_header and mps_user_read_extcfg_page, which call mps_read_config_page, had to be fixed to always set the PageType field. They were implicitly assuming that mps_read_config_page always operated on Extended pages. Reviewed by: ken Approved by: ken (mentor) MFC after: 3 days |
