As reported by Soohoon Lee, the HDIO_GET_32BIT ioctl does not work correctly in compat mode with libata. I have investigated the issue further and found multiple problems that all appeared with the same commit that originally introduced HDIO_GET_32BIT handling in libata back in linux-2.6.8 and presumably also linux-2.4, as the code uses "copy_to_user(arg, &val, 1)" to copy a 'long' variable containing either 0 or 1 to user space. The problems with this are: * On big-endian machines, this will always write a zero because it stores the wrong byte into user space. * In compat mode, the upper three bytes of the variable are updated by the compat_hdio_ioctl() function, but they now contain uninitialized stack data. * The hdparm tool calling this ioctl uses a 'static long' variable to store the result. This means at least the upper bytes are initialized to zero, but calling another ioctl like HDIO_GET_MULTCOUNT would fill them with data that remains stale when the low byte is overwritten. Fortunately libata doesn't implement any of the affected ioctl commands, so this would only happen when we query both an IDE and an ATA device in the same command such as "hdparm -N -c /dev/hda /dev/sda" * The libata code for unknown reasons started using ATA_IOC_GET_IO32 and ATA_IOC_SET_IO32 as aliases for HDIO_GET_32BIT and HDIO_SET_32BIT, while the ioctl commands that were added later use the normal HDIO_* names. This is harmless but rather confusing. This addresses all four issues by changing the code to use put_user() on an 'unsigned long' variable in HDIO_GET_32BIT, like the IDE subsystem does, and by clarifying the names of the ioctl commands.

ahci_xgene: Implement the workaround to fix the missing of the edge interrupt for the HOST_IRQ_STAT. Due to H/W errata, the HOST_IRQ_STAT register misses the edge interrupt when clearing the HOST_IRQ_STAT register and hardware reporting the PORT_IRQ_STAT register happens to be at the same clock cycle.

The flexibility to override the irq handles in the LLD's are already present, so controllers implementing a edge trigger latch can implement their own interrupt handler inside the driver. This patch removes the AHCI_HFLAG_EDGE_IRQ support from libahci and moves edge irq handling to ahci_xgene. tj: Minor update to description. Signed-off-by:

The bulk of ATA host state machine is implemented by ata_sff_hsm_move(). The function is called from either the interrupt handler or, if polling, a work item. Unlike from the interrupt path, the polling path calls the function without holding the host lock and ata_sff_hsm_move() selectively grabs the lock. This is completely broken. If an IRQ triggers while polling is in progress, the two can easily race and end up accessing the hardware and updating state machine state at the same time. This can put the state machine in an illegal state and lead to a crash like the following. kernel BUG at drivers/ata/libata-sff.c:1302! invalid opcode: 0000 [#1] SMP DEBUG_PAGEALLOC KASAN Modules linked in: CPU: 1 PID: 10679 Comm: syz-executor Not tainted 4.5.0-rc1+ #300 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Bochs 01/01/2011 task: ffff88002bd00000 ti: ffff88002e048000 task.ti: ffff88002e048000 RIP: 0010:[<ffffffff83a83409>] [<ffffffff83a83409>] ata_sff_hsm_move+0x619/0x1c60 ...

ata_sff_hsm_move() triggers BUG if it sees a host state machine state that it dind't expect. The risk for data corruption when the condition occurs is low as it's highly unlikely that it would lead to spurious completion of commands. The BUG occasionally triggered for subtle race conditions in the driver. Let's downgrade it to WARN so that it doesn't kill the machine unnecessarily. Signed-off-by:

Some early controllers incorrectly reported zero ports in PORTS_IMPL register and the ahci driver fabricates PORTS_IMPL from the number of ports in those cases. This hasn't mattered but with the new nvme controllers there are cases where zero PORTS_IMPL is valid and should be honored. Disable the workaround for >= AHCI 1.3. Signed-off-by:

The AHCI driver code stops and starts port DMA engines at will without considering the power state of the particular port. The AHCI specification isn't very clear on how to handle this scenario, leaving implementation open to interpretation. Broadcom's STB SATA host controller is unable to handle port DMA controller restarts when the port in question is in low power mode. When a port enters partial or slumber mode, its PHY is powered down. When a controller restart is requested, the controller's internal state machine expects the PHY to be brought back up by software which never happens in this case, resulting in failures. To avoid this situation, logic is added to manually wake up the port just before its DMA engine is stopped, if the port happens to be in a low power state. HBA initiated power management ensures that the port eventually returns to its configured low power state, when the link is idle (as per the conditions listed in the spec). A new host flag is also added to ensure this logic is only exercised for hosts with the above limitation. tj: Formatting changes. Signed-off-by:

If we detect that there is nothing to do just set the flag and do not check if it was already set before. Races really do not matter. If the flag is set by any code then the shepherd will start dealing with the situation and reenable the vmstat workers when necessary again. Since commit 0eb77e98 ("vmstat: make vmstat_updater deferrable again and shut down on idle") quiet_vmstat might update cpu_stat_off and mark a particular cpu to be handled by vmstat_shepherd. This might trigger a VM_BUG_ON in vmstat_update because the work item might have been sleeping during the idle period and see the cpu_stat_off updated after the wake up. The VM_BUG_ON is therefore misleading and no more appropriate. Moreover it doesn't really suite any protection from real bugs because vmstat_shepherd will simply reschedule the vmstat_work anytime it sees a particular cpu set or vmstat_update would do the same from the worker context directly. Even when the two would race the result wouldn't be incorrect as the counters update is fully idempotent. Reported-by:
