If entry is NULL and rc is set to -EMSGSIZE, the\nfollowing code may cause null-pointer dereferences:\n\n  struct vk_msg_blk tmp_msg = entry->to_h_msg[0];\n  set_msg_id(&tmp_msg, entry->usr_msg_id);\n  tmp_msg.size = entry->to_h_blks - 1;\n\nTo prevent these possible null-pointer dereferences, copy to_h_msg,\nusr_msg_id, and to_h_blks from iter into temporary variables, and return\nthese temporary variables to the application instead of accessing them\nthrough a potentially NULL entry.",
