False positive errors when running applications with valgrind.

Default MLNX_OFED libraries are compiled with- out valgrind support and several resources are managed by the kernel.

The following MLNX_OFED libraries are now also compiled with valgrind support:

• libibverbs

• libmlnx4

• libmlx5

• librdmacm

Libraries' files compiled with valgrind support are installed under "/usr/ lib64/mlnx_ofed/valgrind/"

• To run an application over these libraries, thus prevent false positive errors:

  # env LD_LIBRARY_PATH=/usr/ lib64/mlnx_ofed/valgrind/ val- grind [valgrind options] <application cmd>

• To suppress most of valgrind's false positive errors, generate the suppression file:

  #./generate_mlnx_ofed_- supp.sh > mlnx.supp
