Fix filesystem capability support

In linux-2.6.24-rc1, security/commoncap.c:cap_inh_is_capped() was
introduced. It has the exact reverse of its intended behavior. This

To be exposed to this bug, you need to have Filesystem Capabilities

- CONFIG_SECURITY_FILE_CAPABILITIES must be defined for the buggy code
  to be compiled in.

[MIPS] Malta: Fix reading the PCI clock frequency on big-endian

The JMPRS register on Malta boards keeps a 32-bit CPU-endian
value. The readw() function assumes that the value it reads is a
little-endian 16-bit number. Therefore, using readw() to obtain
the value of the JMPRS register is a mistake. This error leads
to incorrect reading of the PCI clock frequency on big-endian
during board start-up.

Change readw() to __raw_readl().

This was tested by injecting a call to printk() and verifying
that the value of the jmpr variable was consistent with current
setting of the JP4 "PCI CLK" jumper.

[NET]: rtnl_link: fix use-after-free

When unregistering the rtnl_link_ops, all existing devices using
the ops are destroyed. With nested devices this may lead to a
use-after-free despite the use of for_each_netdev_safe() in case
the upper device is next in the device list and is destroyed
by the NETDEV_UNREGISTER notifier.

The easy fix is to restart scanning the device list after removing
a device. Alternatively we could add new devices to the front of
the list to avoid having dependant devices follow the device they
depend on. A third option would be to only restart scanning if
dev->iflink of the next device matches dev->ifindex of the current
one. For now this seems like the safest solution.

With this patch, the veth rtnl_link_ops unregistration can use
rtnl_link_unregister() directly since it now also handles destruction
of multiple devices at once.

When packets are flood-forwarded to multiple output devices, the
bridge-netfilter code reuses skb->nf_bridge for each clone to store
the bridge port. When queueing packets using NFQUEUE netfilter takes
a reference to skb->nf_bridge->physoutdev, which is overwritten
when the packet is forwarded to the second port. This causes
refcount unterflows for the first device and refcount leaks for all
others. Additionally this provides incorrect data to the iptables

David S. Miller [Fri, 18 Jan 2008 12:21:39 +0000]
[NET]: Fix interrupt semaphore corruption in Intel drivers.

Several of the Intel ethernet drivers keep an atomic counter used to
manage when to actually hit the hardware with a disable or an enable.

The way the net_rx_work() breakout logic works during a pending
napi_disable() is that it simply unschedules the poll even if it
still has work.

This can potentially leave interrupts disabled, but that is OK
because all of the drivers are about to disable interrupts
anyways in all such code paths that do a napi_disable().

Unfortunately, this trips up the semaphore used here in the Intel
drivers.  If you hit this case, when you try to bring the interface
back up it won't enable interrupts.  A reload of the driver module
fixes it of course.

So what we do is make sure all the sequences now go:

napi_disable();
atomic_set(&adapter->irq_sem, 0);
*_irq_disable();

which makes sure the counter is always in the correct state.

There's currently no way to turn on Lguest guest support; the planned
Kconfig virtualization reorg didn't get into 2.6.25.

This was unnoticed because if you already had CONFIG_LGUEST_GUEST=y in
your config, it worked.  Too bad about new users...

Also, the Kconfig help was wrong now the virtio drivers are merged.

The driver sets up the hardware to accept a frame with max length
equal to MTU + Ethernet header + FCS + VLAN tag, but we neglect to
add the VLAN tag size to the ingress buffer.  When a VLAN-tagged
frame arrives, the hardware passes it, but bad things happen

Carsten Otte [Thu, 17 Jan 2008 23:21:17 +0000]
#ifdef very expensive debug check in page fault path

This patch puts #ifdef CONFIG_DEBUG_VM around a check in vm_normal_page
that verifies that a pfn is valid.  This patch increases performance of the
page fault microbenchmark in lmbench by 13% and overall dbench performance
by 7% on s390x.  pfn_valid() is an expensive operation on s390 that needs a
high double digit amount of CPU cycles.  Nick Piggin suggested that
pfn_valid() involves an array lookup on systems with sparsemem, and
therefore is an expensive operation there too.

The check looks like a clear debug thing to me, it should never trigger on
regular kernels.  And if a pte is created for an invalid pfn, we'll find
out once the memory gets accessed later on anyway.  Please consider
inclusion of this patch into mm.

11 years agocpufreq: Initialise default governor before use
Johannes Weiner [Thu, 17 Jan 2008 23:21:08 +0000]
cpufreq: Initialise default governor before use

When the cpufreq driver starts up at boot time, it calls into the default
governor which might not be initialised yet.  This hurts when the
governor's worker function relies on memory that is not yet set up by its
init function.

This migrates all governors from module_init() to fs_initcall() when being
the default, as was already done in cpufreq_performance when it was the
only possible choice.  The performance governor is always initialized early
because it might be used as fallback even when not being the default.

Fixes at least one actual oops where ondemand is the default governor and
cpufreq_governor_dbs() uses the uninitialised kondemand_wq work-queue
during boot-time.

Devices like the HP Integrated Remote Console Virtual Mouse, which are
standard equipment on all Proliant and Integrity servers, produce
absolute coordinates instead of relative coordinates.  This is done to
synchronize the position of the mouse cursor on the client desktop
with the mouse cursor position on the server.  Mousedev is not
designed to pass those absolute events directly to X, but it can
translate them into relative movements.  It currently does this for
tablet like devices and touchpads.  This patch merely tells it to also
include a device with ABS_X, ABS_Y, and mouse buttons in its list of
devices to process input for.
