During init-time and error-recovery (after a RISC reset), the driver disables interrupts and 'polls' for completions by calling qla2x00_poll(): static inline void qla2x00_poll(scsi_qla_host_t *ha) { ha->isp_ops->intr_handler(0, ha); } which in-turn calls the ISP registered interrupt handler. This patch corrects it by disabling local interrupts during polling.

But mailbox register 0 has the status code for the mailbox command (in this case, Set Target Parameters). Potential values are: /* * ISP mailbox command complete status codes */ So clearly that is in error. I can't think what the author of that line was looking for in a mailbox register, so I just eliminated the AND. flag is used later in the function, and I think that the later usage was also wrong, though it was used to set values that aren't used. Oh well, an overhaul of this driver is not what I want to do now -- just a bugfix. After the fix, I found that my disks were getting a queue depth of 255, which is far too many. Most SCSI disks are limited to 32 or 64. In any case, there's no point, queueing up a bunch of commands to the adapter that will just result in queue full or starve other targets from being issued commands due to running out of internal memory. So I dropped default queue depth to 32 (from which 1 is subtracted elsewhere, giving net of 31). I tested with a Seagate ST336753LC, and results look good, so I'm satisfied with this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the ping tmo is longer than the recv tmo then we could miss a window where we were supposed to check the recv tmo. This happens because the ping code will set the next timeout for the ping timeout, and if the ping executes quickly there will be a long chunk of time before the timer wakes up again. This patch has the ping processing code kick off a recv tmo check when getting a nop in response to our ping.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch fixes a bug in the iscsi nop processing. The target sends iscsi nops to ping the initiator and the initiator has to send nops to reply and can send nops to ping the target. In 2.6.25 we moved the nop processing to the kernel to handle problems when the userspace daemon is not up, but the target is pinging us, and to handle when scsi commands timeout, but the transport may be the cause (we can send a nop to check the transport). When we added this code we added a bug where if the transport timer wakes at the exact same time we are supposed to check for a nop timeout we drop the session instead of checking the transport. This patch checks if a iscsi ping is outstanding and if the ping has timed out, to determine if we need to signal a connection problem.

| * [SCSI] add support for variable length extended commandsBoaz Harrosh2008-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for variable-length, extended, and vendor specific CDBs to scsi-ml. It is now possible for initiators and ULD's to issue these types of commands. LLDs need not change much. All they need is to raise the .max_cmd_len to the longest command they support (see iscsi patch). - clean-up some code paths that did not expect commands to be larger than 16, and change cmd_len members' type to short as char is not enough.

| * [SCSI] Let scsi_cmnd->cmnd use request->cmd bufferBoaz Harrosh2008-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - struct scsi_cmnd had a 16 bytes command buffer of its own. This is an unnecessary duplication and copy of request's cmd. It is probably left overs from the time that scsi_cmnd could function without a request attached. So clean that up. - Once above is done, few places, apart from scsi-ml, needed adjustments due to changing the data type of scsi_cmnd->cmnd. - Lots of drivers still use MAX_COMMAND_SIZE. So I have left that #define but equate it to BLK_MAX_CDB. The way I see it and is reflected in the patch below is. MAX_COMMAND_SIZE - means: The longest fixed-length (*) SCSI CDB as per the SCSI standard and is not related to the implementation. BLK_MAX_CDB. - The allocated space at the request level - I have audit all ISA drivers and made sure none use ->cmnd in a DMA Operation. Same audit was done by Andi Kleen. (*)fixed-length here means commands that their size can be determined by their opcode and the CDB does not carry a length specifier, (unlike the VARIABLE_LENGTH_CMD(0x7f) command). This is actually not exactly true and the SCSI standard also defines extended commands and vendor specific commands that can be bigger than 16 bytes. The kernel will support these using the same infrastructure used for VARLEN CDB's. So in effect MAX_COMMAND_SIZE means the maximum size command scsi-ml supports without specifying a cmd_len by ULD's Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer Dell CERC firmware (>= 6.62) implement a random deletion handling compatible with the legacy megaraid driver. The legacy handling shifted the target ID by 0x80 only for I/O commands (READ/WRITE/etc), whereas megaraid_mbox shifts the target ID always if random deletion is supported. The resulted in megaraid_mbox sending an INQUIRY to the wrong channel, and not finding any devices, obviously. So we disable the random deletion support if the offending firmware is found.
