    i2c-mv64xxx: Fix random oops at boot

    Maxime Bizon authored AdrianBunk committed
    I have a Marvell board which has the same i2c hw block than mv64xxx, so
    I'm trying to use i2c-mv64xxx driver.
    
    But I get the following random oops at boot:
    
    Unable to handle kernel NULL pointer dereference at virtual address 00000002
    Backtrace:

    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.

    corrupted cramfs filesystems cause kernel oops (CVE-2006-5823)

    Phillip Lougher authored AdrianBunk committed
    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.

    handle ext3 directory corruption better (CVE-2006-6053)

    Eric Sandeen authored AdrianBunk committed
    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.

    ext2: skip pages past number of blocks in ext2_find_entry (CVE-2006-6…

    Eric Sandeen authored AdrianBunk committed
    …054)
    
    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.

    [SOUND] Sparc CS4231: Fix IRQ return value and initialization.

    Georg Chini authored AdrianBunk committed
    SBUS: Change IRQ-handler return value from 0 to IRQ_HANDLED and
    fix some initialisation problems.
    
    Change period_bytes_min from 4096 to 256 to allow driver to work with
    low latency (VOIP) applications. Hope this does not break EBUS.
