bus address space is considerably smaller than the CPU's full address
space and non-PCI devices lie outside of the PCI window that we might want

Without this patch, the PCI root bus uses the platform-level bus
resources, and these are then confined to the PCI window, thus making
platform_device_add() reject devices outside of this window.

kernel/signal.c: fix kernel information leak with print-fatal-signals=1

When print-fatal-signals is enabled it's possible to dump any memory
reachable by the kernel to the log by simply jumping to that address from
user space.

Or crash the system if there's some hardware with read side effects.

The fatal signals handler will dump 16 bytes at the execution address,
which is fully controlled by ring 3.

In addition when something jumps to a unmapped address there will be up to
16 additional useless page faults, which might be potentially slow (and at
least is not very efficient)

Fortunately this option is off by default and only there on i386.

But fix it by checking for kernel addresses and also stopping when there's
a page fault.

11 years agocgroups: fix 2.6.32 regression causing BUG_ON() in cgroup_diput()
Dave Anderson [Fri, 8 Jan 2010 22:42:50 +0000 (14:42 -0800)]
cgroups: fix 2.6.32 regression causing BUG_ON() in cgroup_diput()

The LTP cgroup test suite generates a "kernel BUG at kernel/cgroup.c:790!"
here in cgroup_diput():

                 /*
                  * if we're getting rid of the cgroup, refcount should ensure
                  * that there are no pidlists left.
                  */
                 BUG_ON(!list_empty(&cgrp->pidlists));

The cgroup pidlist rework in 2.6.32 generates the BUG_ON, which is caused
when pidlist_array_load() calls cgroup_pidlist_find():

(1) if a matching cgroup_pidlist is found, it down_write's the mutex of the
     pre-existing cgroup_pidlist, and increments its use_count.
(2) if no matching cgroup_pidlist is found, then a new one is allocated, it
     down_write's its mutex, and the use_count is set to 0.
(3) the matching, or new, cgroup_pidlist gets returned back to pidlist_array_load(),
     which increments its use_count -- regardless whether new or pre-existing --
     and up_write's the mutex.

So if a matching list is ever encountered by cgroup_pidlist_find() during
the life of a cgroup directory, it results in an inflated use_count value,
preventing it from ever getting released by cgroup_release_pid_array().
Then if the directory is subsequently removed, cgroup_diput() hits the
BUG_ON() when it finds that the directory's cgroup is still populated with
a pidlist.

The patch simply removes the use_count increment when a matching pidlist
is found by cgroup_pidlist_find(), because it gets bumped by the calling
pidlist_array_load() function while still protected by the list's mutex.

lib: add support for LZO-compressed kernels

This patch series adds generic support for creating and extracting
LZO-compressed kernel images, as well as support for using such images on
the x86 and ARM architectures, and support for creating and using
LZO-compressed initrd and initramfs images.

Russell King said:

: Testing on a Cortex A9 model:
: - lzo decompressor is 65% of the time gzip takes to decompress a kernel
: - lzo kernel is 9% larger than a gzip kernel
:
: which I'm happy to say confirms your figures when comparing the two.
:
: However, when comparing your new gzip code to the old gzip code:
: - new is 99% of the size of the old code
: - new takes 42% of the time to decompress than the old code
:
: What this means is that for a proper comparison, the results get even better:
: - lzo is 7.5% larger than the old gzip'd kernel image
: - lzo takes 28% of the time that the old gzip code took
:
: So the expense seems definitely worth the effort.  The only reason I
: can think of ever using gzip would be if you needed the additional
: compression (eg, because you have limited flash to store the image.)
:
: I would argue that the default for ARM should therefore be LZO.

This patch:

The lzo compressor is worse than gzip at compression, but faster at
extraction.  Here are some figures for an ARM board I'm working on:

Uncompressed size: 3.24Mo
gzip  1.61Mo 0.72s
lzo   1.75Mo 0.48s

So for a compression ratio that is still relatively close to gzip, it's
much faster to extract, at least in that case.

This part contains:
 - Makefile routine to support lzo compression
 - Fixes to the existing lzo compressor so that it can be used in
   compressed kernels
 - wrapper around the existing lzo1x_decompress, as it only extracts one
   block at a time, while we need to extract a whole file here
 - config dialog for kernel compression

OMAP clock/CPUFreq: add clk_exit_cpufreq_table()

A subsequent patch adds code on OMAP2xxx to dynamically allocate the
CPUFreq frequency table in clk_init_cpufreq_table(), so for it to
avoid a leak, it will need a corresponding function to free the
memory.  This patch adds clk_exit_cpufreq_table() with generic
code to call a chip-specific variant inside the clockfw_lock spinlock via

11 years agoomap: gpio: Simultaneously requested rising and falling edge
Cory Maccarrone [Fri, 8 Jan 2010 18:29:04 +0000 (10:29 -0800)]
omap: gpio: Simultaneously requested rising and falling edge

Some chips, namely any OMAP1 chips using METHOD_MPUIO,
OMAP15xx and OMAP7xx, cannot be setup to respond to on-chip GPIO
interrupts in both rising and falling edge directions -- they can
only respond to one direction or the other, depending on how the
ICR is configured.

Additionally, current code forces rising edge detection if both
flags are specified:

        if (trigger & IRQ_TYPE_EDGE_RISING)
                l |= 1 << gpio;
        else if (trigger & IRQ_TYPE_EDGE_FALLING)
                l &= ~(1 << gpio);
        else
                goto bad;

This change implements a toggle function that will modify the ICR
to flip the direction of interrupt for IRQs that are requested with
both rising and falling flags.  The toggle function is not called
for chips and GPIOs it does not apply to through the use of a flip_mask
that's added on a per-bank basis.  The mask is only set for those
GPIOs where a toggle is necessary.  Edge detection starts out the
same as above with FALLING mode first.

The toggle happens on EACH interrupt; without it, we have the
following sequence of actions on GPIO transition:

  ICR    GPIO               Result
  0x1    0 -> 1 (rising)    Interrupt
  0x1    1 -> 0 (falling)   No interrupt

  (set ICR to 0x0 manually)
  0x0    0 -> 1 (rising)    No interrupt
  0x0    1 -> 0 (falling)   Interrupt

That is, with the ICR set to 1 for a gpio, only rising edge interrupts
are caught, and with it set to 0, only falling edge interrupts are
caught.  If we add in the toggle, we get this:

  ICR    GPIO               Result
  0x1    0 -> 1 (rising)    Interrupt (ICR set to 0x0)
  0x0    1 -> 0 (falling)   Interrupt (ICR set to 0x1)
  0x1    0 -> 1 ...

so, both rising and falling are caught, per the request for both
(IRQ_TYPE_EDGE_RISING | IRQ_TYPE_EDGE_FALLING).
