* [SCSI] fcoe: Rearrange fcoe port and NPIV port cleanupNeerav Parikh2011-06-291-37/+49
| | | | | | | | | | | | | | | | | When NPIV port destroy handler is called it does not do all the cleanup required for the given NPIV port. This was happening as some of the lport cleanup moved to fcoe_interface_cleanup() routine, which is not called as part of the vport delete process. This patch rearranges the sequence in which the fcoe_if_destory() and fcoe_interface_cleanup() functions are being called from various places in the code. It now matches the sequence they are constructed during the create process for both N_Port as well as NPIV port.

* [SCSI] tcm_fc: Fixing reference counting problem which was causing ft_sess ↵Kiran Patil2011-06-291-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to be deleted. Problem: After fixing the issue in TCM core w.r.t LUN Reset (Task Management request) , ran into issue where during the completing of this LUN Reset command, reference count of "ft_sess" drops to zero which caused "sess" to be deleted. Fix: As part of handling task management request (e.g. LUN Reset), TCM core function "transport_generic_do_tmr" ends up calling ft_free_cmd which in turn calls "ft_sess_put" (which drops session's reference count by 1) and then frees ft_cmd. Then function "transport_generic_do_tmr" calls "transport_cmd_check_stop" which in turn also calls ft_free_cmd (which calls ft_sess_put - which drops reference count of sess by 1, hence reference count of sess becomes zero and session gets deleted). Fix is to just send response in case of tmr from function "ft_queue_resp_code" and not delete "ft_cmd" (means don't call ft_free_cmd). Earlier code was to send the response code and also free ft_cmd. ft_free_cmd will be freed later after sending response code as a result of "transport_cmd_check_stop" (which calls ft_release_cmd -> ft_free_cmd) being called from "transport_generic_do_tmr" after sening TMR response code.

* [SCSI] libfc:Fix for exchange/seq loopup failure when FCoE stack is used as ↵Kiran Patil2011-06-291-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | target and connected to windows initaitor Problem: Linux based SW target (TCM) connected to windows initiator was unable to satisfy write request of size > 2K. Fix: Existing linux implememtation of FCoE stack is expecting sequence number to match w.r.t incoming framme. When DDP is used on target in response to write request from initiator, SW stack is notified only when last data frame arrives and only the pakcket header of last data frame is posted to NetRx queue of storage. When that last packet was processed in libfc:Exchange layer, implementation was expecting sequence number to match, but in this case sequence number which is embedded in FC Header is assigned by windows initaitor, hence due to sequence number mismatch post-processing which shall result into sending RSP is not done. Enhanced the code to utilize the sequence number of incoming last frame and process the packet so that, it will eventually complete the write request by sending write response (RSP) GOOD. Notes/Dependencies: This patch is validated using windows and linux initiator to make sure, it doesn't break anything.

* [SCSI] fcoe: Amends previous patch, Round-robin based selection of CPU for ↵Kiran Patil2011-06-291-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | post processing of incoming request for FCoE target Problem: Selection of RX queue on target is based on RX-ID. FCoE used 8 Net Rx queues. HW post the packets based on rx_id % num_rx_queue. Due to this has based filtering, only one CPU is busy servicing incoming request including post-processing of incoming request. This is gating factor because 1. Only one CPU is utilized 100% while others CPUs are not used at all. 2. CPU which received request assign "sequence' by selecting exchange from per CPU pool (num_ddp_context / num_online_cpus, approxi.). Due to which if if rate of incoming request is higher than rate of servicing request, existing code path end of sending "BUSY" response (SAM_STAT_BUSY because unable to allocate exchange). Fix: Fan-out incoming request to all other CPUs excluding the CPU which is receiving all incoiming request. This path also addresses, selecting same CPU based on rx_id from received frame for completion of the request such as "releasing exchange to the per CPU Pool". This fix is applicable for FCoE target since initiator code path already takes care of selecting CPU to complete post-processing of request once OX_ID is assigned.

| | | | | | | | | | | | | | | | | | | | incoming commands Problem: Earlier mechanism of selection of CPU was, to select the same CPU which has received incoming request. Hence in case of rx_id = 0xFFFF, request was always posted to same NetRx queue, hence only 1 CPU is utilized for handling the command. It was also causing problem of "running out of exchanges from per CPU pool of exchanges (in case of DDP offload) Fix: Implemented new algo. to select CPU for post-processing of incoming commands when rx_id is unknown.

| | | | | | | | | | | | | | | | | | | | targets Problem: When initiator sends write command to target, target tries to assign new sequence. It allocates new exchangeID (RX_ID) always from non-offloaded pool (Non-offload EMA) Fix: Enhanced fcoe_oem_match routine to look at F_CTL flags and if it is exchange responder and command type is WRITEDATA, then function returns TRUE instead of FALSE. This function is used to determine which pool to use (offload pool of exchange is used only if this function returns TRUE).

* [SCSI] libfc: Enhancement to RPORT state machine applicable only for VN2VN modeKiran Patil2011-06-291-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Existing RPORT state machine continues witg FLOGI/PLOGI process only after it receices beacon from other end. Once claiming stage is over (either clain notify or clain repose), beacon is sent and state machine enters into operational mode where it initiates the rlogin process (FLOGI/PLOGI) to the peer but before this rlogin is initiated, exitsing implementation checks if it received beacon from other end, it beacon is not received yet, rlogin process is not initiated. Other end initiates FLOGI but peer end keeps on rejecting FLOGI, hence after 3 retries other end deletes associated rport, then sends a beacon. Once the beacon is received, peer end now initiates rlogin to the peer end but since associated rport is deleted FLOGI is neither accepted nor the reject response send out because rport is deleted. Hence unable to proceed withg FLOGI/PLOGI process and fails to establish VN2VN connection. Fix: VN2VN spec is not standard yet but based on exitsing collateral on T11, it appears that, both end shall send beacon and enter into 'operational mode' without explictly waiting for beacon from other end. Fix is to allow the RPORT login process as long as respective RPORT is created (as part of claim notification / claim response) even though state of RPORT is INIT. Means don't wait for beacon from peer end, if peer end initiates FLOGI (means peer end exist and responding). Notes: This patch is preparing the FCoE stack for target wrt offload. This is generic patch and harmless even if applied on storage initiator because 'else if' condition of function 'fcoe_oem_found' shall evaluate to TRUE only for targets.

* [SCSI] ses: requesting a fault indicationDouglas Gilbert2011-06-291-1/+5
| | | | | | | | | | | | | | | | | | | | | Noticed that when the sysfs interface of the SCSI SES driver was used to request a fault indication the LED flashed but the buzzer didn't sound. So it was doing what REQUEST IDENT (locate) should do. Changelog: - fix the setting of REQUEST FAULT for the device slot and array device slot elements in the enclosure control diagnostic page - note the potentially defective code that reads the FAULT SENSED and FAULT REQUESTED bits from the enclosure status diagnostic page The attached patch is against git/scsi-misc-2.6 Signed-off-by: Douglas Gilbert <dgilbert@interlog.com> Cc: stable@kernel.org Signed-off-by: James Bottomley <JBottomley@Parallels.com>

* [SCSI] bnx2fc: Fix kernel panic when deleting NPIV portsBhanu Prakash Gollapudi2011-06-293-3/+57
| | | | | | | | | | | | Deleting NPIV port causes a kernel panic when the NPIV port is in the same zone as the physical port and shares the same LUN. This happens due to the fact that vport destroy and unsolicited ELS are scheduled to run on the same workqueue, and vport destroy destroys the lport and the unsolicited ELS tries to access the invalid lport. This patch fixes this issue by maintaining a list of valid lports and verifying if the lport is valid or not before accessing it.
