Subject: cnic: Use proper ulp_ops for per device operations.
X-Git-Tag: v3.14-rc8~3^2~14^2~2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f7bd12d09ed6e4093a56dbbfbe8411cc52a738d1;p=pandora-kernel.git

cnic: Use proper ulp_ops for per device operations.

For per device operations, cnic needs to dereference the RCU protected
cp->ulp_ops instead of the global cnic_ulp_tbl.  In 2 locations,
cnic_send_nlmsg() and cnic_copy_ulp_stats(), it was referencing the
global table.  If the device has been unregistered and these functions
are still being called (very unlikely scenarios), it could lead to NULL
pointer dereference.
