Sergey Gorenko 8ede4d6c67 IB/iser: Always check sig MR before putting it to the free pool ... [ Upstream commit 26e28deb813eed908cf31a6052870b6493ec0e86 ] libiscsi calls the check_protection transport handler only if SCSI-Respose is received. So, the handler is never called if iSCSI task is completed for some other reason like a timeout or error handling. And this behavior looks correct. But the iSER does not handle this case properly because it puts a non-checked signature MR to the free pool. Then the error occurs at reusing the MR because it is not allowed to invalidate a signature MR without checking. This commit adds an extra check to iser_unreg_mem_fastreg(), which is a part of the task cleanup flow. Now the signature MR is checked there if it is needed.
