[virt-tools-list] [vhostmd PATCH 17/18] vhostmd: Fix memory leak in vhostmd_run

[Jim Fehlig]

Example from coverity scan

vhostmd-1.1/vhostmd/vhostmd.c:940: alloc_arg: "vu_buffer_create" allocates memory that is stored into "buf".
vhostmd-1.1/vhostmd/vhostmd.c:959: leaked_storage: Variable "buf" going out of scope leaks the storage it points to.
  957|            vu_log(VHOSTMD_ERR, "Failed to start virtio thread '%s'\n",
  958|                   strerror(rc));
  959|->          return -1;
  960|         }
  961|      }
