Hi, I am not sure if this the correct place to post an issues with new LIO TCM target code. I am using fedora 16 (3.1.0-7.fc16.x86_64) and every time I try to setup multi-pathing my target server crashes. Any help would be much appreciated. thanks fil here is the crash [ 1026.964899] TARGET_CORE[iSCSI]: Expected Transfer Length: 4096 does not match SCSI CDB Length: 512 for SAM Opcode: 0x28 [ 1026.967700] BUG: unable to handle kernel NULL pointer dereference at 000000000000000c [ 1026.968631] IP: [<ffffffffa0356063>] iscsit_map_iovec+0x54/0xf6 [iscsi_target_mod] [ 1026.968631] PGD 0 [ 1026.968631] Oops: 0000 [#1] SMP [ 1026.968631] CPU 0 [ 1026.968631] Modules linked in: tcm_loop tcm_fc libfc scsi_transport_fc scsi_tgt iscsi_target_mod target_core_pscsi target_core_file target_core_iblock target_core_mod configfs fuse btrfs zlib_deflate libcrc32c ufs qnx4 hfsplus hfs minix vfat msdos fat jfs xfs reiserfs lockd sunrpc joydev i2c_piix4 i2c_core virtio_net virtio_balloon virtio_blk [last unloaded: scsi_wait_scan] [ 1026.968631] [ 1026.968631] Pid: 1886, comm: iscsi_ttx Not tainted 3.1.0-7.fc16.x86_64 #1 Bochs Bochs [ 1026.968631] RIP: 0010:[<ffffffffa0356063>] [<ffffffffa0356063>] iscsit_map_iovec+0x54/0xf6 [iscsi_target_mod] [ 1026.968631] RSP: 0018:ffff88007104dd40 EFLAGS: 00010206 [ 1026.968631] RAX: 0000000000000000 RBX: ffff880071198000 RCX: ffff880075a67000 [ 1026.968631] RDX: 0000000000000000 RSI: 0000000000000200 RDI: 0000000000000000 [ 1026.968631] RBP: ffff88007104dda0 R08: ffff88007131f970 R09: 0000000000989680 [ 1026.968631] R10: ffff88007fc12f80 R11: ffff88007fc12f80 R12: ffff88007131f970 [ 1026.968631] R13: 0000000000000001 R14: 0000000000000e00 R15: ffff880000000000 [ 1026.968631] FS: 00007fcb61757700(0000) GS:ffff88007fc00000(0000) knlGS:0000000000000000 [ 1026.968631] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b [ 1026.968631] CR2: 000000000000000c CR3: 0000000073c96000 CR4: 00000000000006f0 [ 1026.968631] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 1026.968631] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 1026.968631] Process iscsi_ttx (pid: 1886, threadinfo ffff88007104c000, task ffff8800371d0000) [ 1026.968631] Stack: [ 1026.968631] ffff88007104dd50 ffffea0001d699c0 ffff88007131f970 ffffffff00000200 [ 1026.968631] ffff880000000000 ffff880073f23320 ffff88007104dd80 ffff880071198000 [ 1026.968631] ffff880073ccac00 00000000ffffffff ffff8800711980a4 ffff8800711980ec [ 1026.968631] Call Trace: [ 1026.968631] [<ffffffffa035a84e>] iscsi_target_tx_thread+0x668/0x1b0b [iscsi_target_mod] [ 1026.968631] [<ffffffff8100e04e>] ? load_TLS+0x10/0x14 [ 1026.968631] [<ffffffff8100e6e0>] ? __switch_to+0xc6/0x220 [ 1026.968631] [<ffffffffa035a1e6>] ? iscsit_close_connection+0x621/0x621 [iscsi_target_mod] [ 1026.968631] [<ffffffff81072d17>] kthread+0x84/0x8c [ 1026.968631] [<ffffffff814be5f4>] kernel_thread_helper+0x4/0x10 [ 1026.968631] [<ffffffff81072c93>] ? kthread_worker_fn+0x148/0x148 [ 1026.968631] [<ffffffff814be5f0>] ? gs_change+0x13/0x13 [ 1026.968631] Code: e2 ff 0f 00 00 c1 ef 0c 49 89 f4 41 89 ce 48 c1 e7 05 48 03 bb e8 04 00 00 89 93 08 05 00 00 48 89 bb 00 05 00 00 e9 80 00 00 00 <8b> 77 0c 48 8b 0f 45 89 e8 89 55 c0 48 89 7d c8 29 d6 44 39 f6 [ 1026.968631] RIP [<ffffffffa0356063>] iscsit_map_iovec+0x54/0xf6 [iscsi_target_mod] [ 1026.968631] RSP <ffff88007104dd40> [ 1026.968631] CR2: 000000000000000c [ 1027.039775] ---[ end trace 25349b016c16ad4b ]--- Message from syslogd@unknown210 at Nov 14 05:07:05 ... kernel:[ 1026.968631] Oops: 0000 [#1] SMP Message from syslogd@unknown210 at Nov 14 05:07:05 ... kernel:[ 1026.968631] Stack: Message from syslogd@unknown210 at Nov 14 05:07:05 ... kernel:[ 1026.968631] Call Trace: Message from syslogd@unknown210 at Nov 14 05:07:05 ... kernel:[ 1026.968631] Code: e2 ff 0f 00 00 c1 ef 0c 49 89 f4 41 89 ce 48 c1 e7 05 48 03 bb e8 04 00 00 89 93 08 05 00 00 48 89 bb 00 05 00 00 e9 80 00 00 00 <8b> 77 0c 48 8b 0f 45 89 e8 89 55 c0 48 89 7d c8 29 d6 44 39 f6 Message from syslogd@unknown210 at Nov 14 05:07:05 ... kernel:[ 1026.968631] CR2: 000000000000000c -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
