Maher Sanalla 8d67953978 RDMA/uverbs: Propagate errors from rdma_lookup_get_uobject() ... [ Upstream commit 81f8f7454a ] Currently, the IB uverbs API calls uobj_get_uobj_read(), which in turn uses the rdma_lookup_get_uobject() helper to retrieve user objects. In case of failure, uobj_get_uobj_read() returns NULL, overriding the error code from rdma_lookup_get_uobject(). The IB uverbs API then translates this NULL to -EINVAL, masking the actual error and complicating debugging. For example, applications calling ibv_modify_qp that fails with EBUSY when retrieving the QP uobject will see the overridden error code EINVAL instead, masking the actual error. Furthermore, based on rdma-core commit: "2a22f1ced5f3 ("Merge pull request #1568 from jakemoroni/master")" Kernel's IB uverbs return values are either ignored and passed on as is to application or overridden with other errnos in a few cases. Thus, to improve error reporting and debuggability, propagate the original error from rdma_lookup_get_uobject() instead of replacing it with EINVAL.
