Fix CID 1324733: Null pointer dereferences (FORWARD_NULL) Fix CID 1324734: Null pointer dereferences (FORWARD_NULL) Fix CID 1324735: Null pointer dereferences (FORWARD_NULL) Fix CID 1324736: Null pointer dereferences (FORWARD_NULL) Fix CID 1324737: Null pointer dereferences (FORWARD_NULL) Fix CID 1324751: Memory - illegal accesses (USE_AFTER_FREE) Fix CID 1324750: (USE_AFTER_FREE) Fix CID 1324749: Memory - corruptions (USE_AFTER_FREE) Fix CID 1324748: Memory - illegal accesses (USE_AFTER_FREE) Fix CID 1324747: (USE_AFTER_FREE) Fix CID 1324746: Memory - corruptions (USE_AFTER_FREE) Add missing return on an error path. Fix CID 1324745: Code maintainability issues (UNUSED_VALUE) Ignore return code from barrier. It was not being used anyway. Fix CID 1324738: Null pointer dereferences (FORWARD_NULL) Fix CID 1324741: Null pointer dereferences (REVERSE_INULL) module->selected_btl can not be NULL in osc/rdma during normal operation. Removed the unnecessary NULL check. Fix CID 1324752: Memory - illegal accesses (USE_AFTER_FREE) Move ompi_osc_pt2pt_module_lock_remove to before the lock is freed. Fix CID 1324744: Uninitialized variables (UNINIT) Fix CID 1324743: Uninitialized variables (UNINIT) This array is not used unitialized but there is no reason not to use calloc here to silence the warning. The following CID is a false positive: 1324742. I will mark it such in coverity. Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
