The Bluetooth L2CAP layer has 2 locks that are used in softirq context,
(one spinlock and one rwlock, where the softirq usage is readlock) but
where not all usages of the lock were _bh safe. The patch below corrects
this.

There exists no attempt do deal with the fact that a structure with
a uint32_t followed by a pointer is going to be different for 32-bit
and 64-bit userspace. Any 32-bit process trying to use it will be
failing with -EFAULT if it's lucky; suffering from having data dumped
at a random address if it's not.

This patch lets BT_HIDP depend on instead of select INPUT. This fixes
the following warning during an s390 build:
net/bluetooth/hidp/Kconfig:4:warning: 'select' used by config symbol
'BT_HIDP' refer to undefined symbol 'INPUT'
A dependency on INPUT also implies !S390 (and therefore makes the
explicit dependency obsolete) since INPUT is not available on s390.
The practical difference should be nearly zero, since INPUT is always
set to y unless EMBEDDED=y (or S390=y).

Ramiro Voicu hits the BUG_ON(!pte_none(*pte)) in zeromap_pte_range: kernel
bugzilla 7645. Right: read_zero_pagealigned uses down_read of mmap_sem,
but another thread's racing read of /dev/zero, or a normal fault, can
easily set that pte again, in between zap_page_range and zeromap_page_range
getting there. It's been wrong ever since 2.4.3.
The simple fix is to use down_write instead, but that would serialize reads
of /dev/zero more than at present: perhaps some app would be badly
affected. So instead let zeromap_page_range return the error instead of
BUG_ON, and read_zero_pagealigned break to the slower clear_user loop in
that case - there's no need to optimize for it.
Use -EEXIST for when a pte is found: BUG_ON in mmap_zero (the other user of
zeromap_page_range), though it really isn't interesting there. And since
mmap_zero wants -EAGAIN for out-of-memory, the zeromaps better return that
than -ENOMEM.

It's a known fact that Windows times out commands after 7 seconds, so
drives generally try and respond if they can before that happens. We
default to 5 seconds, which sometimes is a bit too short.
Jeremy Higdon reported here:
http://lkml.org/lkml/2007/1/1/145
that his drive takes longer than 5 seconds for a "read track
information" command, later confirming that it is about 6.7 seconds.
So just do the sane thing and change the default command timeout to 7
seconds to avoid other surprises.

The whole idea with the NOTRACK netfilter target is that
you can force the netfilter code to avoid connection
tracking, and all costs assosciated with it, by making
traffic match a NOTRACK rule.
But this is totally broken by the fact that we do a checksum
calculation over the packet before we do the NOTRACK bypass
check, which is very expensive. People setup NOTRACK rules
explicitly to avoid all of these kinds of costs.
This patch from Patrick, already in Linus's tree, fixes the
bug.
Move the check for ip_conntrack_untracked before the call to
skb_checksum_help to fix NOTRACK excemptions from NAT. Pre-2.6.19
NAT code breaks TSO by invalidating hardware checksums for every
packet, even if explicitly excluded from NAT through NOTRACK.
2.6.19 includes a fix that makes NAT and TSO live in harmony,
but the performance degradation caused by this deserves making
at least the workaround work properly in -stable.

The oops is caused by a spurious interrupt that occurs when request_irq
is called. mv64xxx_i2c_fsm() tries to read drv_data->msg, which is NULL.
I noticed that hardware init is done after requesting irq. Thus any
pending irq from previous hardware usage may cause this.

Steve Grubb's fzfuzzer tool (http://people.redhat.com/sgrubb/files/
fsfuzzer-0.6.tar.gz) generates corrupt Cramfs filesystems which cause
Cramfs to kernel oops in cramfs_uncompress_block(). The cause of the oops
is an unchecked corrupted block length field read by cramfs_readpage().
This patch adds a sanity check to cramfs_readpage() which checks that the
block length field is sensible. The (PAGE_CACHE_SIZE << 1) size check is
intentional, even though the uncompressed data is not going to be larger
than PAGE_CACHE_SIZE, gzip sometimes generates compressed data larger than
the original source data. Mkcramfs checks that the compressed size is
always less than or equal to PAGE_CACHE_SIZE << 1. Of course Cramfs could
use the original uncompressed data in this case, but it doesn't.

I've been using Steve Grubb's purely evil "fsfuzzer" tool, at
http://people.redhat.com/sgrubb/files/fsfuzzer-0.4.tar.gz
Basically it makes a filesystem, splats some random bits over it, then
tries to mount it and do some simple filesystem actions.
At best, the filesystem catches the corruption gracefully. At worst,
things spin out of control.
As you might guess, we found a couple places in ext3 where things spin out
of control :)
First, we had a corrupted directory that was never checked for
consistency... it was corrupt, and pointed to another bad "entry" of
length 0. The for() loop looped forever, since the length of
ext3_next_entry(de) was 0, and we kept looking at the same pointer over and
over and over and over... I modeled this check and subsequent action on
what is done for other directory types in ext3_readdir...
(adding this check adds some computational expense; I am testing a followup
patch to reduce the number of times we check and re-check these directory
entries, in all cases. Thanks for the idea, Andreas).
Next we had a root directory inode which had a corrupted size, claimed to
be > 200M on a 4M filesystem. There was only really 1 block in the
directory, but because the size was so large, readdir kept coming back for
more, spewing thousands of printk's along the way.
Per Andreas' suggestion, if we're in this read error condition and we're
trying to read an offset which is greater than i_blocks worth of bytes,
stop trying, and break out of the loop.
With these two changes fsfuzz test survives quite well on ext3.

This one was pointed out on the MOKB site:
http://kernelfun.blogspot.com/2006/11/mokb-09-11-2006-linux-26x-ext2checkpage.html
If a directory's i_size is corrupted, ext2_find_entry() will keep processing
pages until the i_size is reached, even if there are no more blocks associated
with the directory inode. This patch puts in some minimal sanity-checking
so that we don't keep checking pages (and issuing errors) if we know there
can be no more data to read, based on the block count of the directory inode.
This is somewhat similar in approach to the ext3 patch I sent earlier this
year.

Ran into BUG() while doing madvise(REMOVE) testing. If we are punching a
hole into shared memory segment using madvise(REMOVE) and the entire hole
is below the indirect blocks, we hit following assert.
BUG_ON(limit <= SHMEM_NR_DIRECT);

This changes the microsecond RTT sampling so that samples are taken in
the same way that RTT samples are taken for the RTO calculator: on the
last segment acknowledged, and only when the segment hasn't been
retransmitted.

Makes UML compile on any possible processor choice. The two problems were:
*) x86 code, when 386 is selected, checks at runtime boot_cpuflags, which we
not have.
*) 3Dnow support for memcpy() et al. does not compile currently and fixing t
is not trivial, so simply disable it; with this change, if one selects MK
UML compiles (while it did not).
Merged upstream.

The line:
hp->Mode &= !RIO_PCI_INT_ENABLE;
is obviously wrong as RIO_PCI_INT_ENABLE=0x04 and is used as a bitmask
2 lines before. Getting no IRQ would not disable RIO_PCI_INT_ENABLE
but rather RIO_PCI_BOOT_FROM_RAM which equals 0x01.
Obvious fix is to change ! for ~.
