We can race and misset the suspend bit if iscsi_write_space is called then iscsi_send returns with a failure indicating there is no space. To handle this this patch returns a error upwards allowing xmitworker to decide if we need to try and transmit again. For the no write space case xmitworker will not retry, and instead let iscsi_write_space queue it back up if needed (this relies on the work queue code to properly requeue us if needed).

If recovery failed or we are in recovery only overwrite the state if we are going to terminate the session or if we logged back in. STOP_CONN_SUSPEND and conn_cnt are not used. We only support a single connection session ATM, so cleanup that code while we are working around it. Signed-off-by:

(LSI Logic / Symbios Logic SAS1064E PCI-Express Fusion-MPT SAS (rev 01)) o Problem is easily reproducible, if system crashed while some disk activity like cp operation was going on. o After a system crash, devices are not shutdown and capture kernel starts booting while skipping BIOS. Hence underlying device is left in operational state. In this case scsi contoller was left with interrupt line asserted reply FIFO was not empty. When driver starts initializing in the second kernel, it receives the interrupt the moment request_irq() is called. Interrupt handler, reads the message from reply FIFO and tries to access the associated message frame and panics, as in the new kernel's context that message frame is not valid at all. o In this scenario, probably we should delay the request_irq() call. First bring up the IOC, reset it if needed and then should register for irq. o I have tested the patch with SAS1064E and 53c1030 controllers.

max_id now means the maximum number of ids on the bus, which means it is one greater than the largest possible id number. Signed-off-by: -
Amit Arora authored
The scsi_scan_host_selected() should return -EINVAL when the id is equal to the max_id. Currently it uses ">" when comparing with max_id, and hence leaves the border case when "id==max_id". The channel and lun have values valid from 0 up to, and including, max_channel or max_lun. But, the valid values for id range from 0 to max_id-1. This patch fixes the problem. Signed-off-by:

If zfcp's port erp fails we now call fc_remote_port_delete. This helps to avoid offlined scsi devices if scsi commands time out due to path failures. When an adapter erp fails we call fc_remote_port_delete for all ports on that adapter. Signed-off-by:

Do not flush queues then block session. This will cause commands to needlessly swing around on us and remove goofy recovery_failed field and replace with state value. And do not start recovery from within the host reset function. This causeis too many problems becuase open-iscsi was desinged to call out to userspace then have userpscae decide if we should go into recovery or kill the session. Signed-off-by:

Discovered by steven@hayter.me.uk and patch by michaelc@cs.wisc.edu The dtask mempool is reserving 261120 items per session! Since we are now sending headers with sendmsg there is no reason for the mempool and that was causing us to us carzy amounts of mem. We can preallicate a header in the r2t and task struct and reuse them Signed-off-by:

The Coverity checker found a memory leak (bug nr. 1245) in drivers/block/DAC960.c::DAC960_V2_ProcessCompletedCommand() The leak is pretty unlikely since it requires that the first of two successive kmalloc() calls fail while the second one succeeds. But it can still happen even if it's unlikely. If the first call that allocates 'PhysicalDeviceInfo' fails but the one that allocates 'InquiryUnitSerialNumber' succeeds, then we will leak the memory allocated to 'InquiryUnitSerialNumber' when the variable goes out of scope. A simple fix for this is to change the existing code that frees 'PhysicalDeviceInfo' if that one was allocated but 'InquiryUnitSerialNumber' was not, into a check for either pointer being NULL and if so just free both. This is safe since kfree() can deal with being passed a NULL pointer and it avoids the leak. While I was there I also removed the casts of the kmalloc() return value since it's pointless. I also updated the driver version since this patch changes the workings of the code (however slightly). This issue could probably be fixed a lot more elegantly, but the code is a big mess IMHO and I just took the least intrusive route to a fix that I could find instead of starting on a cleanup as well (that can come later). Please consider for inclusion. Signed-off-by:
