commit: 06e97b489006f28e23bb028febfa1c01c266d676 From: Steve Hodgson <[email protected]> Date: Fri, 16 Nov 2012 08:06:17 -0800 Subject: qla2xxx: Look up LUN for abort requests
Search through the list of pending commands on the session list to find the command the initiator is actually aborting, so that we can pass the correct LUN to the core TMR handling code. (nab: Allow abort requests to work to LUN=0 with mainline target code) Signed-off-by: Steve Hodgson <[email protected]> Signed-off-by: Roland Dreier <[email protected]> Cc: [email protected] Signed-off-by: Nicholas Bellinger <[email protected]> --- drivers/scsi/qla2xxx/qla_target.c | 21 ++++++++++++++++++++- 1 files changed, 20 insertions(+), 1 deletions(-) diff --git a/drivers/scsi/qla2xxx/qla_target.c b/drivers/scsi/qla2xxx/qla_target.c index 62aa558..661d33e 100644 --- a/drivers/scsi/qla2xxx/qla_target.c +++ b/drivers/scsi/qla2xxx/qla_target.c @@ -1264,8 +1264,27 @@ static int __qlt_24xx_handle_abts(struct scsi_qla_host *vha, struct abts_recv_from_24xx *abts, struct qla_tgt_sess *sess) { struct qla_hw_data *ha = vha->hw; + struct se_session *se_sess = sess->se_sess; struct qla_tgt_mgmt_cmd *mcmd; + struct se_cmd *se_cmd; + u32 lun = 0; int rc; + bool found_lun = false; + + spin_lock(&se_sess->sess_cmd_lock); + list_for_each_entry(se_cmd, &se_sess->sess_cmd_list, se_cmd_list) { + struct qla_tgt_cmd *cmd = + container_of(se_cmd, struct qla_tgt_cmd, se_cmd); + if (cmd->tag == abts->exchange_addr_to_abort) { + lun = cmd->unpacked_lun; + found_lun = true; + break; + } + } + spin_unlock(&se_sess->sess_cmd_lock); + + if (!found_lun) + return -ENOENT; ql_dbg(ql_dbg_tgt_mgt, vha, 0xf00f, "qla_target(%d): task abort (tag=%d)\n", @@ -1283,7 +1302,7 @@ static int __qlt_24xx_handle_abts(struct scsi_qla_host *vha, mcmd->sess = sess; memcpy(&mcmd->orig_iocb.abts, abts, sizeof(mcmd->orig_iocb.abts)); - rc = ha->tgt.tgt_ops->handle_tmr(mcmd, 0, TMR_ABORT_TASK, + rc = ha->tgt.tgt_ops->handle_tmr(mcmd, lun, TMR_ABORT_TASK, abts->exchange_addr_to_abort); if (rc != 0) { ql_dbg(ql_dbg_tgt_mgt, vha, 0xf052, -- 1.7.3.4 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
