2006-11-14libata: fix double-completion on errorDarrick J. Wong
A curious thing happens, however, when ata_qc_new_init fails to get an ata_queued_cmd: First, ata_qc_new_init handles the failure like this: cmd->result = (DID_OK << 16) | (QUEUE_FULL << 1); done(cmd); Then, we return to ata_scsi_translate and do this: err_mem: cmd->result = (DID_ERROR << 16); done(cmd); It appears to me that first we set a status code indicating that we're ok but the device queue is full and finish the command, but then we blow away that status code and replace it with an error flag and finish the command a second time! That does not seem to be desirable behavior since we merely want the I/O to wait until a command slot frees up, not send errors up the block layer. In the err_mem case, we should simply exit out of ata_scsi_translate instead. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-11-13IB/mad: Fix race between cancel and receive completionRoland Dreier
When ib_cancel_mad() is called, it puts the canceled send on a list and schedules a "flushed" callback from process context. However, this leaves a window where a receive completion could be processed before the send is fully flushed. This is fine, except that ib_find_send_mad() will find the MAD and return it to the receive processing, which results in the sender getting both a successful receive and a "flushed" send completion for the same request. Understandably, this confuses the sender, which is expecting only one of these two callbacks, and leads to grief such as a use-after-free in IPoIB. Fix this by changing ib_find_send_mad() to return a send struct only if the status is still successful (and not "flushed"). The search of the send_list already had this check, so this patch just adds the same check to the search of the wait_list. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-11-13[PATCH] SCSI core: always store >= 36 bytes of INQUIRY dataAlan Stern
This patch (as810c) copies a minimum of 36 bytes of INQUIRY data, even if the device claims that not all of them are valid. Often badly behaved devices put plausible data in the Vendor, Product, and Revision strings but set the Additional Length byte to a small value. Using potentially valid data is certainly better than allocating a short buffer and then reading beyond the end of it, which is what we do now.

On sparc64, after probing the device, we'll delete the PCI device via pci_remove_bus_device() if we cannot find the firmware device tree node corresponding to it. This is fine, but at this point the sysfs files for the PCI device won't be setup yet. So we should not try to do anything in pci_remove_sysfs_dev_files() if pci_sysfs_init() has not run yet.
