I am testing the LIO iSCSI target with the Windows Certification Kit and I observe that the CHAP tests (one-way and mutual) fail and that one of the failures is caused by a regression since linux v3.10. The one-way CHAP test performs the following checks: 1/ valid response is returned using hexadecimal encoding 2/ valid response is returned using base64 encoding 3/ invalid response is returned using hexadecimal encoding 4/ invalid response is returned using base64 encoding I expect the base64 tests to fail since there is no support for base64 encoded CHAP responses in LIO. My problem is with the third test "invalid response with hexadecimal encoding": the Windows Certification Kit displays the following error: Failed to receive the next login response PDU from the target I observed that this test works with Linux v3.9 so I ran a bisection between v3.9 and v3.10. Here are the results: # good: [3f99306] iscsi-target: Add iscsit_transport API template git bisect good 3f99306337ba1871afc8568e8b36004ce3cee039 # only skipped commits left to test # possible first bad commit: [cdb7266] iscsi-target: Add per transport iscsi_cmd alloc/free # possible first bad commit: [03aa207] iscsi-target: Add iser-target parameter keys + setup during login # possible first bad commit: [baa4d64] iscsi-target: Initial traditional TCP conversion to iscsit_transport I skipped some commits because I got compilation errors with them. So now, I have an indication of when the regression was introduced but I did not manage to determine where the error is precisely in the code. I ran network captures with `tcpdump` that you will find attached. The "whql-chap-invalid-resp-hexa*" PCAP files are shorter versions of the two other PCAP files and contain only the packets sent during the "invalid response with hexadecimal encoding" test. The target is 192.168.3.81 and the initiator is 192.168.3.88. In the network dumps, I observe that packet 8 is correctly decoded as "Login Response (Authentication failed)" in the v3.9 trace but not in the v3.15 trace. Do you have any clue about this issue? Or maybe suggestions on how I can further investigate this bug? Best regards, -- Christophe Vu-Brugier
