More detail is available on in comments 11 through 13 on PR259152. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D259152#c11 A pcap demonstrating this issue is in an attachment on that PR, https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D228924 Summary of the specific issue here: In frame 15 we send a Login Command containing MaxRecvDataSegmentLength=3D2= 62144. The response in frame 17 does not contain a MaxRecvDataSegmentLength. As a result we never update conn->conn_max_recv_data_segment_length in usr.sbin/iscsid/login.c login_negotiate_key(). In frame 189 we issue a read with ExpectedDataTransferLength: 0x00004000. The response is in frame 192 with DataSegmentLength 0x00004000. We then drop the connection with: WARNING: icl_conn_receive_pdu: received data segment length 16384 is larger than negotiated; dropping connection Referenced Bugs: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D259152 [Bug 259152] [iscsi] OCI oracle iscsi block device problems --=20 You are receiving this mail because: You are the assignee for the bug.=
