firewire: prevent userspace from accessing shut down devices

If userspace ignores the POLLERR bit from poll(), and only attempts to
read() the device when POLLIN is set, it can still make ioctl() calls on
a device that has been removed from the system.  The node_id and
generation returned by GET_INFO will be outdated, but INITIATE_BUS_RESET
would still cause a bus reset, and GET_CYCLE_TIMER will return data.
And if you guess the correct generation to use, you can send requests to
a different device on the bus, and get responses back.

This patch prevents open, ioctl, compat_ioctl, and mmap against shutdown
devices.

When a cpu really is stuck in the kernel, it can be often
impossible to figure out which cpu is stuck where.  The
worst case is when the stuck cpu has interrupts disabled.

Therefore, implement a global cpu state capture that uses
SMP message interrupts which are not disabled by the
normal IRQ enable/disable APIs of the kernel.

As long as we can get a sysrq 'y' to the kernel, we can

we can trigger it from userspace using /proc/sysrq-trigger

The output is made compact so that this facility is more

Fixups to ATA ACPI hotplug

The libata-acpi.c code currently accepts hotplug messages from both the

driver, and may result in confusion when two hotplug requests are

to removable ACPI devices, which in turn allows it to use the _STA
method to determine whether the device has been removed or inserted.
On removal, devices are marked as detached. On insertion, a hotplug scan
is started. This should avoid lockups caused by the ata layer attempting
to scan devices which have been removed. The uevent sending is moved

libata: kill hotplug related race condition

Originally, whole reset processing was done while the port is frozen
and SError was cleared during @postreset().  This had two race
conditions.  1: hotplug could occur after reset but before SError is
cleared and libata won't know about it.  2: hotplug could occur after
all the reset is complete but before the port is thawed.  As all
events are cleared on thaw, the hotplug event would be lost.

Commit ac371987a81c61c2efbd6931245cdcaf43baad89 kills the first race
by clearing SError during link resume but before link onlineness test.
However, this doesn't fix race #2 and in some cases clearing SError
after SRST is a good idea.

This patch solves this problem by cross checking link onlineness with
classification result after SError is cleared and port is thawed.
Reset is retried if link is online but all devices attached to the
link are unknown.  As all devices will be revalidated, this one-way
check is enough to ensure that all devices are detected and
revalidated reliably.

This, luckily, also fixes the cases where host controller returns
bogus status while harddrive is spinning up after hotplug making
classification run before the device sends the first FIS and thus
causes misdetection.

Low level drivers can bypass the logic by setting class explicitly to
ATA_DEV_NONE if ever necessary (currently none requires this).

This patch cleans up sata_promise's mmio accesses.

In sata_promise there are three distinct mmio address spaces:

2. per-port ATA registers, offsets from ap->ioaddr.cmd_addr
3. per-port SATA registers, offsets from ap->ioaddr.scr_addr

The driver currently often fails to indicate which address space
a given mmio base pointer refers to, which is a source of bugs
and confusion (see recent pdc_thaw() irq clearing bug; it's also
been an obstacle for the pending NCQ extensions).

To reduce these problems, adopt a coding style where the name of
a base pointer always indicates which address space it refers to:
1. global registers: host_mmio
2. per-port ATA registers: ata_mmio
3. per-port SATA registers: sata_mmio

Also rearrange register offset definitions to clearly indicate
which address space they belong to, and add a symbolic definition

2. pdc_thaw() incorrectly added the PDC_INT_SEQMASK host register

sata_mv: consolidate main_irq_mask updates

Part two of simplifying/fixing handling of the main_irq_mask register
to resolve unexpected interrupt issues observed in 2.6.26-rc*.

Consolidate all updates of the host main_irq_mask register
into a single function.  This simplifies maintenance,
and also prepares the way for caching it (later).

No functionality changes in this update.

16 years agosata_mv: don't blindly enable IRQs

sata_mv: don't blindly enable IRQs

Part one of simplifying/fixing handling of the main_irq_mask register
to resolve unexpected interrupt issues observed in 2.6.26-rc*.

Don't blindly enable port IRQs at host init time.
Instead, enable only the bits that we want,
which in this case is simply the PCI_ERR bit.

The per-port bits can wait until the ports are reset/probed for devices.

16 years agosata_mv: async notify for genIIe only

sata_mv: async notify for genIIe only

Now that we handle the FIS_IRQ_CAUSE register correctly,
we can also now handle SATA asynchronous notification events.

So enable them, but only for the more modern GenIIe chips.
(older chips have unaddressed errata issues related to this).

This fixes hot plug/unplug for port-muliplier ports.

sata_mv: group genIIe flags

Group all of the flags for GenIIe devices into a common definition,
to ensure that any updates to them are shared by all GenIIe devices.

This will help make future maintenance somewhat simpler.

16 years agosata_mv: fis irq register fixes

sata_mv: fis irq register fixes

Fix handling of the FIS_IRQ_CAUSE register in sata_mv.

This register exists *only* on GenIIe devices, so don't bother
writing to it on older chips.  Also, it has to be read/cleared
in mv_err_intr() before clearing the main ERR_IRQ_CAUSE register.

This keeps sata_mv from getting stuck forever on certain error types.
