When did ib_srpt start registering sessions with target node GUID? I
thought it used the port GUID on target side.
ib_srpt used to use {target port GUID + initiator port GUID}
as session name
ib_srpt recently changed to use full initiator_port_ID
(128-bit) as session name to register session.
You can look at commit 15f6176b9bcc7b8122eb799b38deb09ece83bbab
init_completion(&ch->scst_sess_done);
sprintf(ch->sess_name, "0x%016llx%016llx",

*)&sdev->port[param->port - 1].gid.raw[8]),
- (unsigned long long)be64_to_cpu(*(u64 *)
(ch->i_port_id + 8)));
+ (unsigned long long)be64_to_cpu(*(u64
*)ch->i_port_id),
+ (unsigned long long)be64_to_cpu(*(u64
*)(ch->i_port_id + 8)));
ch->scst_sess =
scst_register_session(sdev->scst_tgt, 1,
ch->sess_name,
ch,
srpt_register_channel_done);

Change the local buffer allocator to use a spin-lock

been observed with the result that the same data buffer
was used for
more than one SCSI operation, either writing the wrong
data to the disk
or sending the wrong data to the initiator.
