2009-12-04[SCSI] libiscsi: add warm target reset tmf supportMike Christie1-1/+1
This implements warm target reset tmf support for the scsi-ml target reset callback. Previously we would just drop the session in that callback. This patch will now try a target reset and if that fails drop the session. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
2009-12-04[SCSI] bnx2i: use common iscsi suspend queueMike Christie2-8/+1
This just has bnx2i use the iscsi_suspend_queue helper. The suspend works as follows: When ep_poll has succeeed iscsid will call conn_bind, the LLD will then call iscsi_conn_bind which will clear the suspend bit. When ep_disconnect is called (or if there is a conn error) we set the suspend bit. For the ep_disconnect case I added a helper in the previous kernel that will take the session lock to make sure iscsi_queuecommand/xmit_task is not running and it will set the suspend bit.

2009-10-02[SCSI] bnx2i: Fix context mapping issue for architectures with PAGE_SIZE != 4096Anil Veerabhadrappa2-1/+3
5706/5708/5709 devices allow driver/user to set page size. By default it is set to 4096. Current drivers do not program this register based on architecture type (e.g. x86 = 4K, IA64 = 16K) and by choice lets device use the defaults. So while mapping connection context memory (doorebll registers), driver has to match page size used by the device. Included change fixes the issue we uncovered during IA64 testing Signed-off-by: Anil Veerabhadrappa <anilgv@broadcom.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

2009-08-22[SCSI] bnx2i : Fix "cid #n not valid" issueAnil Veerabhadrappa1-2/+1
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: Anil Veerabhadrappa <anilgv@broadcom.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
2009-08-22[SCSI] bnx2i : Fix command session number jump issue seen during cable pull testAnil Veerabhadrappa1-3/+0
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: Anil Veerabhadrappa <anilgv@broadcom.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
2009-08-22[SCSI] bnx2i: register given device with cnic if shost != NULL in ep_connect()Anil Veerabhadrappa2-4/+10
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 <anilgv@broadcom.com> Reviewed-by: Michael Chan <mchan@broadcom.com> Reviewed-by Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

convert bnx2i_dev_lock to type mutex from rwlock_t because cnic->register_device() can sleep for various reasons including memory allocation, waiting for ISCSI_INIT completion and while acquiring mutex lock, cnic_lock.

Fixed bnx2i_init_one() to properly handle return code of cnic->register_device() and propagate it back to the caller.
