x86: ioapic: Cleanup sparse irq code

Switch over to the new allocator and remove all the magic which was
caused by the unability to destroy irq descriptors. Get rid of the

10 years agox86: Don't setup ioapic irq for sci twice

x86: Don't setup ioapic irq for sci twice

The sparseirq rework triggered a warning in the iommu code, which was
caused by setting up ioapic for ACPI irq 9 twice. This function is
solely to handle interrupts which are on a secondary ioapic and
outside the legacy irq range.

Replace the sparse irq_to_desc check with a non ifdeffed version.

10 years agogenirq: Implement a sane sparse_irq allocator
Thomas Gleixner [Mon, 27 Sep 2010 15:48:26 +0000]
genirq: Implement a sane sparse_irq allocator

The current sparse_irq allocator has several short comings due to
failures in the design or the lack of it:

 - Requires iteration over the number of active irqs to find a free slot
   (Some architectures have grown their own workarounds for this)
 - Removal of entries is not possible
 - Racy between create_irq_nr and destroy_irq (plugged by horrible
   callbacks)
 - Migration of active irq descriptors is not possible
 - No bulk allocation of irq ranges
 - Sprinkeled irq_desc references all over the place outside of kernel/irq/
   (The previous chip functions series is addressing this issue)

Implement a sane allocator which fixes the above short comings (though
migration of active descriptors needs a full tree wide cleanup of the
direct and mostly unlocked access to irq_desc).

The new allocator still uses a radix_tree, but uses a bitmap for
keeping track of allocated irq numbers. That allows:

 - Fast lookup of a free slot
 - Allows the removal of descriptors
 - Prevents the create/destroy race
 - Bulk allocation of consecutive irq ranges
 - Basic design is ready for migration of life descriptors after
   further cleanups

The bitmap is also used in the SPARSE_IRQ=n case for lookup and
raceless (de)allocation of irq numbers. So it removes the requirement
for looping through the descriptor array to find slots.

Right now it uses sparse_irq_lock to protect the bitmap and the radix
tree, but after cleaning up all users we should be able convert that
to a mutex and to switch the radix_tree and decriptor allocations to
GFP_KERNEL.

mfd: twl4030: Fix dummy irq chip usage

The twl irqchip uses the dummy irq chip ack functions, which is NULL
now. Switch it over to use irq_ack.

This option covers now the old chip functions and the irq_desc data
fields which are moving to struct irq_data. More stuff will follow.

Pretty handy for testing a conversion, whether something broke or not.

genirq: Provide advanced irq chip functions

The low level irq chip functions want access to irq_desc->irq_data.
Provide new functions which hand down irq_data instead of the irq
number so these functions avoid to call irq_to_desc() which is a radix
tree lookup in case of sparse irq.

This provides all the old functions except one: end(). end() is a
relict of __do_IRQ() and will just go away with the __do_IRQ() code.

The replacement for set_affinity() has an extra argument "bool
force". The reason for this is to notify the low level code, that the
move has to be done right away and cannot be delayed until the next
interrupt happens. That's necessary to handle the irq fixup on cpu
unplug in the generic code.

genirq: Create irq_data

Low level chip functions need access to irq_desc->handler_data,
irq_desc->chip_data and irq_desc->msi_desc. We hand down the irq
number to the low level functions, so they need to lookup irq_desc.
With sparse irq this means a radix tree lookup.

We could hand down irq_desc itself, but low level chip functions have
no need to fiddle with it directly and we want to restrict access to
irq_desc further.

Preparatory patch for new chip functions.

Note, that the ugly anon union/struct is there to avoid a full tree
wide clean up for now. This is not going to last 3 years like __do_IRQ()

Commit e40cc4bdfd4b89813f072f72bd9c7055814d3f0f introduced
a build breakage if CONFIG_SMP is undefined. This commit
fixes the problem.

This fix is only a workaround. For a real fix, cpu_sibling_mask() should
be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be
included directly. This fix is currently not possible because asm/smp.h defines
cpu_sibling_mask() unconditionally and is included directly from many source
files.

10 years agotcp: Fix >4GB writes on 64-bit.
David S. Miller [Tue, 28 Sep 2010 03:24:54 +0000]
tcp: Fix >4GB writes on 64-bit.

Fixes kernel bugzilla #16603

tcp_sendmsg() truncates iov_len to an 'int' which a 4GB write to write
zero bytes, for example.

There is also the problem higher up of how verify_iovec() works.  It
wants to prevent the total length from looking like an error return
value.

However it does this using 'int', but syscalls return 'long' (and
thus signed 64-bit on 64-bit machines).  So it could trigger
false-positives on 64-bit as written.  So fix it to use 'long'.

Dan Rosenberg [Mon, 27 Sep 2010 16:30:28 +0000]
Fix pktcdvd ioctl dev_minor range check

The PKT_CTRL_CMD_STATUS device ioctl retrieves a pointer to a
pktcdvd_device from the global pkt_devs array.  The index into this
array is provided directly by the user and is a signed integer, so the
comparison to ensure that it falls within the bounds of this array will
fail when provided with a negative index.

This can be used to read arbitrary kernel memory or cause a crash due to
an invalid pointer dereference.  This can be exploited by users with
permission to open /dev/pktcdvd/control (on many distributions, this is
readable by group "cdrom").

Sven Eckelmann [Mon, 27 Sep 2010 22:54:44 +0000]
net/9p: Mount only matching virtio channels

p9_virtio_create will only compare the the channel's tag characters
against the device name till the end of the channel's tag but not till
the end of the device name. This means that if a user defines channels
with the tags foo and foobar then he would mount foo when he requested
foonot and may mount foo when he requested foobar.

Thus it is necessary to check both string lengths against each other in
case of a successful partial string match.

de2104x: fix ethtool

When the interface is up, using ethtool breaks it because:
a) link is put down but media_timer interval is not shortened to NO_LINK
b) rxtx is stopped but not restarted

Also manual 10baseT-HD (and probably FD too - untested) mode does not work -
the link is forced up, packets are transmitted but nothing is received.
Changing CSR14 value to match documentation (not disabling link check) fixes this.

tcp: fix TSO FACK loss marking in tcp_mark_head_lost

When TCP uses FACK algorithm to mark lost packets in
tcp_mark_head_lost(), if the number of packets in the (TSO) skb is
greater than the number of packets that should be marked lost, TCP
incorrectly exits the loop and marks no packets lost in the skb. This
underestimates tp->lost_out and affects the recovery/retransmission.
This patch fargments the skb and marks the correct amount of packets
lost.
