When bnx2i_adapter_ready() fails, connection handle(cid) = 0 is wrongly freed because 'cid' is not yet allocated for the endpoint. Fix is to initialize bnx2i_ep->ep_iscsi_cid to '-1' in bnx2i_alloc_ep() and not in bnx2i_ep_connect() to avoid releasing invalid 'cid'. There is already a check in bnx2i_free_iscsi_cid() not to free invalid iscsi connection handle (-1) Signed-off-by: NAnil Veerabhadrappa <anilgv@broadcom.com> Signed-off-by: NJames Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: NJames Bottomley <James.Bottomley@suse.de>

Without the fix bnx2i would fail tt->xmit_task() when link is down and libiscsi would have already incremented session->cmdsn before calling bnx2i's xmit_task() entry point and will just return the command to SCSI-ML when xmit_task() fails. libiscsi does not retract the session->cmdsn as the command was never sent on wire. It is generally good idea for LLD, bnx2i to accept the scsi cmnd/nopout and let upper layer timeout and go though normal session recovery process. When link is down, unsolicited nopout will not be accepted by bnx2i and connection will never enter recovery state. This fix is required for MPIO to work corectly Signed-off-by: NAnil Veerabhadrappa <anilgv@broadcom.com> Signed-off-by: NJames Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: NJames Bottomley <James.Bottomley@suse.de>

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: NAnil Veerabhadrappa <anilgv@broadcom.com> Reviewed-by: NMichael Chan <mchan@broadcom.com> Reviewed-by Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: NJames Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: NJames Bottomley <James.Bottomley@suse.de>
