From fac3cc458fc2f8272bcc1ff1903474ff41715723 Mon Sep 17 00:00:00 2001 From: Anil Veerabhadrappa Date: Wed, 8 Jul 2009 18:21:01 -0700 Subject: [PATCH] [SCSI] bnx2i: register given device with cnic if shost != NULL in ep_connect() When using iface, bnx2i was unable to offload further connections after all active sessions are logged out. bnx2i will unregister the device from cnic when the last connection is torn down. Next call to ep_connect() will fail because the device is not registered. This issue is not seen if shost == NULL is passed to ep_connect() call because in that case bnx2i will registers all known devices with cnic before doing a route look-up. When shost != NULL, bnx2i knows the device on which to offload the connection and has to register this device before attempting to offload the connection Signed-off-by: Anil Veerabhadrappa Reviewed-by: Michael Chan Reviewed-by Mike Christie Signed-off-by: James Bottomley Signed-off-by: James Bottomley --- drivers/scsi/bnx2i/bnx2i_init.c | 7 +++++-- drivers/scsi/bnx2i/bnx2i_iscsi.c | 7 +++++-- 2 files changed, 10 insertions(+), 4 deletions(-) diff --git a/drivers/scsi/bnx2i/bnx2i_init.c b/drivers/scsi/bnx2i/bnx2i_init.c index fd78540ffc95..0c4210d48ee8 100644 --- a/drivers/scsi/bnx2i/bnx2i_init.c +++ b/drivers/scsi/bnx2i/bnx2i_init.c @@ -185,14 +185,17 @@ void bnx2i_stop(void *handle) */ void bnx2i_register_device(struct bnx2i_hba *hba) { + int rc; + if (test_bit(ADAPTER_STATE_GOING_DOWN, &hba->adapter_state) || test_bit(BNX2I_CNIC_REGISTERED, &hba->reg_with_cnic)) { return; } - hba->cnic->register_device(hba->cnic, CNIC_ULP_ISCSI, hba); + rc = hba->cnic->register_device(hba->cnic, CNIC_ULP_ISCSI, hba); - set_bit(BNX2I_CNIC_REGISTERED, &hba->reg_with_cnic); + if (!rc) + set_bit(BNX2I_CNIC_REGISTERED, &hba->reg_with_cnic); } diff --git a/drivers/scsi/bnx2i/bnx2i_iscsi.c b/drivers/scsi/bnx2i/bnx2i_iscsi.c index f7412196f2f8..98148f3f3c63 100644 --- a/drivers/scsi/bnx2i/bnx2i_iscsi.c +++ b/drivers/scsi/bnx2i/bnx2i_iscsi.c @@ -1653,15 +1653,18 @@ static struct iscsi_endpoint *bnx2i_ep_connect(struct Scsi_Host *shost, struct iscsi_endpoint *ep; int rc = 0; - if (shost) + if (shost) { /* driver is given scsi host to work with */ hba = iscsi_host_priv(shost); - else + /* Register the device with cnic if not already done so */ + bnx2i_register_device(hba); + } else /* * check if the given destination can be reached through * a iscsi capable NetXtreme2 device */ hba = bnx2i_check_route(dst_addr); + if (!hba) { rc = -ENOMEM; goto check_busy; -- 2.39.5
