| * [SCSI] fix race in scsi_target_reapAlan Stern2010-05-251-4/+5
| | | | | | | | | | | | | | | | | | | | | | This patch (as1357) fixes a race in SCSI target allocation and release. Putting a target in the STARGET_DEL state isn't protected by the host lock, so an old target structure could be reused by a new device even though it's about to be deleted. The cure is to change the state while still holding the host lock. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

| * [SCSI] ipr: improve interrupt service routine performanceWayne Boyer2010-05-241-33/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | During performance testing on P7 machines it was observed that the interrupt service routine was doing unnecessary MMIO operations. This patch rearranges the logic of the routine and moves some of the code out of the main routine. The result is that there are now fewer MMIO operations in the performance path of the code.

| * [SCSI] ipr: set the data list length in the request control blockWayne Boyer2010-05-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | In bring up testing for the new 64 bit adapters, the first read command failed after loading the driver. The cause was that the command requires more than one scatter gather element and the corresponding code to set the data list length in the request control block was missing. This patch adds the correct assignment.

| * [SCSI] ipr: fix a register read to use the correct address for 64 bit adaptersWayne Boyer2010-05-242-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix ipr_reset_enable_ioa() to read the correct IOA to host interrupt register address for 64 bit adapters. We need to read the lower 32 bits, not the upper 32 bits. Also change the write of the 64 bit mask value to a single writeq instead of two writel calls. Finally, use the correct u8 type for the type field in the ipr_resource_entry structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This function should return 0 on error. Returning -1 would cause a crash. Also there is an extra space before the newline character and a missing space between the "for" and the "mgmt_invalidate_icds". I put the string on one line.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The removal of the 'waitqueue_active()' test in commit d7d05548a6 ("[SCSI] iscsi_tcp: fix relogin/shutdown hang") got incorrectly resolved by David when he back-merged the main git tree into the networking tree in commit 278554bd65 ("Merge branch 'master' of master.kernel.org:..."). There was a content conflict due to 'sock->sk->sk_sleep' being changed into 'sk_sleep(sock->sk)' in the networking tree, but David didn't pick up the iscsi change from the main tree.

So you end up with a "dead" device entry. And some of the linux tools go slightly wonky. Solution: --------- Based on the notification from FW, the driver calls "scsi_remove_device" for the DELETED drive. This call not only informs the scsi device status to the SCSI mid layer and also it will remove corresponding scsi device entries from the Linux sysfs.

If N is the last block address reported, then should not be able to read past N, i.e. N+1. But in their case, reported last LBA=143134719. So should not have been able to read with LBA=143134720, but it is read without failure, which means reported size to the OS is not correct and is less than the actual last block address. Solution: --------- Firmware layer exposes lesser container capacity than the actual one. It exposes [Actual size - Spitfire space(10MB)] to the OS, IO's to the 10MB should be prohibited from the Linux driver. Driver checks LBA boundary, if its greater than the array reported size then sets sensekey to HARDWARE_ERROR and sends the notification to the MID layer.

When the "CC" bit is set by the host in ATA pass-through CDB - Even for the successful completion, SCSI target shall generate check condition. - Driver returns a result code of SAM_STAT_CHECK_CONDITION, with a driver byte of DID_OK to the mid layer. Below is the snippet of existing code which fills a result code of SAM_STAT_CHECK_CONDITION: *********************************** if (le32_to_cpu(srbreply->scsi_status) == SAM_STAT_CHECK_CONDITION) { int len; scsicmd->result |= SAM_STAT_CHECK_CONDITION; .......... ************************************ 2. When the "CC" bit is reset by the host and if SCSI target generates a check condition when an error occurs. - Driver returns a result code of SAM_STAT_CHECK_CONDITION, with a driver byte of DID_ERROR to the mid layer.

| | * | | [SCSI] aacraid: expose physical devices for models with newer firmwareRajashekhara, Mahesh2010-05-161-0/+15

If the user wants to expose connected physical drives, enable "expose_physicals" module parameter. With the new JBOD firmware, physical drives are not available for "expose_physicals>0". In function "aac_expose_phy_device", modified to reset the appropriate bit in the first byte of inquiry data. This fix exposes the connected physical drives.

Solution: --------- AIF handling: If there is a JBOD drive added to the system, identify the old one with scsi_device_lookup() and remove it to enable a fresh scsi_add_device(); else the new JBOD is not available until reboot.
