When RPI is not available, driver sends WQE with invalid RPI value and rejected by HBA. lpfc 0000:82:00.3: 1:3154 BLS ABORT RSP failed, data: x3/xa0320008 and lpfc :2753 PLOGI failure DID:FFFFFA Status:x3/xa0240008 In this case, driver accesses rpi_ids array out of bounds. Fix: Check return value of lpfc_sli4_alloc_rpi(). Do not allocate lpfc_nodelist entry if RPI is not available. When RPI is not available, we will get discovery timeouts and command drops for some of the vports as seen below. lpfc :0273 Unexpected discovery timeout, vport State x0 lpfc :0230 Unexpected timeout, hba link state x5 lpfc :0111 Dropping received ELS cmd Data: x0 xc90c55 x0 Signed-off-by: Dick Kennedy <dick.kennedy@broadcom.com> Signed-off-by: James Smart <james.smart@broadcom.com> Reviewed-by: Johannes Thumshirn <jthumshirn@suse.de>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
