Herbert Xu 122cedfa33 lib/mpi: Fix buffer overrun when SG is too long ... BugLink: https://bugs.launchpad.net/bugs/2017706 [ Upstream commit 7361d1bc307b926cbca214ab67b641123c2d6357 ] The helper mpi_read_raw_from_sgl sets the number of entries in the SG list according to nbytes. However, if the last entry in the SG list contains more data than nbytes, then it may overrun the buffer because it only allocates enough memory for nbytes.
