      forcedeth: fix multi irq issues · ebf34c9b
      Ayaz Abdulla authored 
      This patch fixes the issues with multiple irqs.

I am resending based on feedback. I decoupled the dma mask for
consistent memory and fixed leak with multiple irq in error path.

Thanks to Manfred for catching the spin lock problem.

      [PATCH] via-rhine: zero pad short packets on Rhine I ethernet cards · 3e0d167a
      Craig Brind authored 
      Fixes Rhine I cards disclosing fragments of previously transmitted frames
in new transmissions.

Before transmission, any socket buffer (skb) shorter than the ethernet
minimum length of 60 bytes was zero-padded.  On Rhine I cards the data can
later be copied into an aligned transmission buffer without copying this
padding.  This resulted in the transmission of the frame with the extra
bytes beyond the provided content leaking the previous contents of this
buffer on to the network.

Now zero-padding is repeated in the local aligned buffer if one is used.

Following a suggestion from the via-rhine maintainer, no attempt is made
here to avoid the duplicated effort of padding the skb if it is known that
an aligned buffer will definitely be used.  This is to make the change
"obviously correct" and allow it to be applied to a stable kernel if
necessary.  There is no change to the flow of control and the changes are
only to the Rhine I code path.

The patch has run on an in-service Rhine-I host without incident.  Frames
shorter than 60 bytes are now correctly zero-padded when captured on a
separate host.  I see no unusual stats reported by ifconfig, and no unusual
log messages.

      [PATCH] mv643xx_eth: provide sysfs class device symlink · b0b8dab2

The SET_NETDEV_DEV has to be done before a call to register_netdev.  With
the new patch below, the device symlink for the platform device was
created.  Unfortunately, after the 4 ls commands, the network connection
died.  No idea if the box crashed or if something else broke, lost remote
access.

Provide sysfs 'device' in /class/net/ethN Also, set module owner field,
like pcnet32 driver does.

      [PATCH] splice: fix page LRU accounting · a893b99b
      Jens Axboe authored 
      Currently we rely on the PIPE_BUF_FLAG_LRU flag being set correctly
to know whether we need to fiddle with page LRU state after stealing it,
however for some origins we just don't know if the page is on the LRU
list or not.

So remove PIPE_BUF_FLAG_LRU and do this check/add manually in pipe_to_file()
instead.

      Jens Axboe authored 
      We need to use the minium of {len, PAGE_SIZE-off}, not {len, PAGE_SIZE}-off.
The latter doesn't make any sense, and could cause us to attempt negative

      [NETFILTER] x_tables: fix compat related crash on non-x86 · 46c5ea3c
      Patrick McHardy authored 
      When iptables userspace adds an ipt_standard_target, it calculates the size
of the entire entry as:

sizeof(struct ipt_entry) + XT_ALIGN(sizeof(struct ipt_standard_target))

ipt_standard_target looks like this:

  struct xt_standard_target
  {
        struct xt_entry_target target;
        int verdict;
  };

xt_entry_target contains a pointer, so when compiled for 64 bit the
structure gets an extra 4 byte of padding at the end. On 32 bit
architectures where iptables aligns to 8 byte it will also have 4
byte padding at the end because it is only 36 bytes large.

The compat_ipt_standard_fn in the kernel adjusts the offsets by

  sizeof(struct ipt_standard_target) - sizeof(struct compat_ipt_standard_target),

which will always result in 4, even if the structure from userspace
was already padded to a multiple of 8. On x86 this works out by
accident because userspace only aligns to 4, on all other
architectures this is broken and causes incorrect adjustments to
the size and following offsets.

Thanks to Linus for lots of debugging help and testing.

      [PATCH] x86_64: make PC Speaker driver work · 160bd18e
      Mikael Pettersson authored 
      The PC Speaker driver's ->probe() routine doesn't even get called in the
64-bit kernels.  The reason for that is that the arch code apparently has
to explictly add a "pcspkr" platform device in order for the driver core to
call the ->probe() routine.  arch/i386/kernel/setup.c unconditionally adds
a "pcspkr" device, but the x86_64 kernel has no code at all related to the
PC Speaker.

The patch below copies the relevant code from i386 to x86_64, which makes
the PC Speaker work for me on x86_64.
