If there is IO going to the volume while a hidden disk is being torn down, there is a case where we would return a DID_NO_CONNECT for IO sent to the volume. The end result is the volume goes read-only. This problem is due to the fact the firmware mapped target ids saved in per device object is phys_disk_num for hidden raid components, and target_id for the volume. There is a single case when both phys_disk_num and target_id are equal, so enters this issue. We fix this issue by checking the tflags when the device is torned down, insuring the IO being completed is meant for hidden raid component, not the volume. In addition to this fix, there are a couple other cases to address hidden raid components. For instance task_abort and device reset are not supported by mpt fw for hidden raid components, a bus reset would be required or target reset to volume. Signed-off-by:

I was investigating strange driver behaviour and thought that readable code and proper visible types might help explain why it didn't work right the moment a second SCB was outstanding to the controller. I was right - Cleanup, linuxise, demacro - Remove the BSD dual licence on the new work - Switch the if ALPHA to if __LP64__. (struct size is then right elsewhere) and then to CONFIG_64BIT as per Christoph's request - Fix the recursive locking on a reset. This is the only actual real code change (I hope ;)). I'm not clear what the right way to handle the BIOS param stuff is on n on x86-32/64. Using phys_to_virt and stuff is ugly and probably doesn't make sense elsewhere Still has a couple of odd things - and there seems to be a commonly shared EEPROM handling error several drivers have. Roughly speaking several SCSI drivers go try and read EEPROM It failed.. Write any changes between the default and the data we read Which is great as for some paths we've no idea what was in before, so each boot won't write it all back, won't checksum but will repeat the bug Also it can still sleep for a second with IRQ off, and there is some dubious looking error path locking marked FIXME in case anyone feels inspired to work on it. Not a newly introduced bug, and at least its now marked. Signed-off-by:

When a target scan is initiated from sysfs, we should check the portstate prior to invoke scsi_scan_target(). Otherwise scsi_scan_target() might oops as the rport might already been removed from the scsi host and the traversal from the rport to the scsi_host in scsi_scan_target() will fail. Also the portstate already told us that communication with the target has failed, so it's quite pointless to try. Signed-off-by:

Adds an eh_host_reset_handler to ibmvscsi which resets the connection to the vscsi server. This patch also adds a timer to internally issues commands to prevent client hangs in the case of a misbehaving server. Tested by modifying the VIOS such that it would occasionally drop one or more request in sequence. Signed-off-by:

Converts ibmvscsi to use dev_printk and friends to simplify debugging. ibmvscsi adapter initialization now looks like this: ibmvscsi 30000005: SRP_VERSION: 16.a ibmvscsi 30000005: partner initialization complete ibmvscsi 30000005: sent SRP login ibmvscsi 30000005: SRP_LOGIN succeeded Additionally, this patch adds the logging of a couple return codes in a couple logs.

Add the ability for an application to issue a hardware reset to the adapter via sysfs. Typical uses include restarting the adapter after it has been flashed. Bumped revision number for the driver and added a feature to periodically check the adapter's health (check_interval), update the adapter's concept of time (update_interval) and block checking/resetting of the adapter (check_reset).

Sundry cleanups: 1) Use kzalloc instead of kmalloc. 2) Make sure probe worked before recalling the SCSI command to finalize processing. 3) _aac_probe_container2 and _aac_probe_container1 return value goes unused, change return to void. 4) Use a lower depth pointer reference to pick up the driver instance variable. 5) Although effectively unused except to fake for scsicmd validity, set the scsi_done in probe code to aac_probe_container_callback1 instead of the less valid dummy reference to _aac_probe_container1. 6) SCp.phase is set in aac_valid_context, drop setting up this value in caller when unnecessary. 7) take container target id at the beginning, rather than referencing scmd_id() to pick it up. There should be no side effects or functionality changes. Signed-off-by:

Description: 1. Implement PCI-Express error recovery function and AER capability, especially thanks to Yanmin Zhang's openhanded help about AER 2. Implement the selection of ARCMSR_MAX_XFER_SECTORS_B=4096 if firmware version is latter than 1.42 3. Add arcmsr_done4_abort_postqueue in arcmsr_iop_reset function to improve the stability as hot-unplug/plug 4. Modify the ISR, arcmsr_interrupt routine, to prevent the inconsistency with sg_mod driver if application directly calls the arcmsr driver w/o passing through scsi midlayer Signed-off-by:Nick Cheng <nick.cheng@areca.com.tw> [jejb: unused variable removal] Signed-off-by:

iSCSI must support software iscsi (iscsi_tcp, iser), hardware iscsi (qla4xxx), and partial offload (broadcom). To be able to allow each stack or driver or port (virtual or physical) to be able to log into the same target portal we use the initiator tuple [[HWADDRESS | NETDEVNAME], INITIATOR_NAME] and the target tuple [TARGETNAME, CONN_ADDRESS, CONN_PORT] to id a session. This patch adds the netdev name, which is used by software iscsi when it binds a session to a netdevice using the SO_BINDTODEVICE sock opt. It cannot use HWADDRESS because if someone did vlans then the same netdevice will have the same mac and the initiator,target id will not be unique. Signed-off-by:

This patch exports the local address for the session. For qla4xxx this is the ip of the hba's port. For software this is the src addr of the socket. Signed-off-by:

This patch should fix the file descriptor leak problem. A quick look through the kernel shows that users of sockfd_lookup use sockfd_put to release their handle. We were using sock_release which from the comments and code look like it does not release the get() on the file from the lookup. Signed-off-by:

Userspace will want to know what the driver/FW/HW capabilites when it comes to some operations like if the hardware can do discovery or if it can store iscsi info like what target was used for boot. This patch adds some new caps so userspace can tell if the driver supports hardware/fw based sendtargets discovery and if the hardware has some flash which may be holding or can contain some iscsi target info .

If we got the padding, data and header in different skbs, we were not handling the padding correctly because we attributed it to the data's skb. This resulted in the initiator reading from pad bytes + skb offset instead of the correct offset. If you could not connect with the open solaris target, this will fix the lock up problem you were hitting. Signed-off-by:

This patch allows us to set can_queue and cmds_per_lun from userspace when we create the session/host. From there we can set it on a per target basis. The patch fully converts iscsi_tcp, but only hooks up ib_iser for cmd_per_lun since it currently has a lots of preallocations based on can_queue. Signed-off-by:
