Author: slm Date: Mon Jun 20 18:14:51 2016 New Revision: 302031 URL: https://svnweb.freebsd.org/changeset/base/302031
Log: - No log bit in IOCStatus and endian-safe changes. Use MPI2_IOCSTATUS_MASK when checking IOCStatus to mask off the log bit, and make a few more things endian-safe. - Fix possible use of invalid pointer. It was possible to use an invalid pointer to get the target ID value. To fix this, initialize a local Target ID variable to an invalid value and change that variable to a valid value only if the pointer to the Target ID is not NULL. - No need to set the MPSSAS_SHUTDOWN flag because it's never used. - done_ccb pointer can be used if it is NULL. To prevent this, move check for done_ccb == NULL to before done_ccb is used in mpssas_stop_unit_done(). - Disks can go missing until a reboot is done in some cases. This is due to the DevHandle not being released, which causes the Firmware to not allow that disk to be re-added.
