[PATCH] scsi: qedf: remove memset/memcpy to nfunc and use func instead
by Yang Yingliang 24 Jul '20

24 Jul '20

From: Colin Ian King <colin.king(a)canonical.com> mainline inclusion from mainline-v5.2-rc3 commit 65b1dc99008de592f7c1c8e5fad446824791b4da category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- Currently the qedf_dbg_* family of functions can overrun the end of the source string if it is less than the destination buffer length because of the use of a fixed sized memcpy. Remove the memset/memcpy calls to nfunc and just use func instead as it is always a null terminated string. Addresses-Coverity: ("Out-of-bounds access") Fixes: 61d8658b4a43 ("scsi: qedf: Add QLogic FastLinQ offload FCoE driver framework.")
