Pull networking fixes from David Miller:

 1) New sysctl ndisc_notify needs some documentation, from Hanns
    Frederic Sowa.

 2) Netfilter REJECT target doesn't set transport header of SKB
    correctly, from Mukund Jampala.

 3) Forcedeth driver needs to check for DMA mapping failures, from Larry
    Finger.

 4) brcmsmac driver can't use usleep_range while holding locks, use
    udelay instead.  From Niels Ole Salscheider.

 5) Fix unregister of netlink bridge multicast database handlers, from
    Vlad Yasevich and Rami Rosen.

 6) Fix checksum calculations in netfilter's ipv6 network prefix
    translation module.

 7) Fix high order page allocation failures in netfilter xt_recent, from
    Eric Dumazet.

 8) mac802154 needs to use netif_rx_ni() instead of netif_rx() because
    mac802154_process_data() can execute in process rather than
    interrupt context.  From Alexander Aring.

 9) Fix splice handling of MSG_SENDPAGE_NOTLAST, otherwise we elide one
    tcp_push() too many.  From Eric Dumazet and Willy Tarreau.

10) Fix skb->truesize tracking in XEN netfront driver, from Ian
    Campbell.

Merge tag 'nfs-for-3.8-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

2013-01-07T16:36:45+00:00

Pull NFS client bugfixes from Trond Myklebust:

 - Fix a permissions problem when opening NFSv4 files that only have the
   exec bit set.

 - Fix a couple of typos in pNFS (inverted logic), and the mount parsing
   (missing pointer dereference).

 - Work around a series of deadlock issues due to workqueues using
   struct work_struct pointer address comparisons in the re-entrancy
   tests.  Ensure that we don't free struct work_struct prematurely if
   our work function involves waiting for completion of other work items
   (e.g. by calling rpc_shutdown_client).

 - Revert the part of commit 168e4b3 that is causing unnecessary
   warnings to be issued in the nfsd callback code.

* tag 'nfs-for-3.8-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs:

  SUNRPC: Ensure that we free the rpc_task after cleanups are done

tcp: fix MSG_SENDPAGE_NOTLAST logic

2013-01-07T04:58:13+00:00

commit 35f9c09fe9c72e (tcp: tcp_sendpages() should call tcp_push() once)
added an internal flag : MSG_SENDPAGE_NOTLAST meant to be set on all
frags but the last one for a splice() call.

The condition used to set the flag in pipe_to_sendpage() relied on
splice() user passing the exact number of bytes present in the pipe,
or a smaller one.

But some programs pass an arbitrary high value, and the test fails.

The effect of this bug is a lack of tcp_push() at the end of a
splice(pipe -> socket) call, and possibly very slow or erratic TCP
sessions.

We should both test sd->total_len and fact that another fragment
is in the pipe (pipe->nrbufs > 1)

Many thanks to Willy for providing very clear bug report, bisection
and test programs.

ext4: fix configuration dependencies for ext4 ACLs and security labels

2013-01-07T04:38:44+00:00

Commit "ext4: Remove CONFIG_EXT4_FS_XATTR" removed the configuration
dependencies for ext4 xattrs from the ext4 ACLs and security labels
configuration options, but did not replace them with a dependency on
ext4 itself.  Add back the dependency on ext4 so the options only show
up if ext4 is enabled.

NFS: Ensure that we free the rpc_task after read and write cleanups are done

2013-01-04T17:59:10+00:00

This patch ensures that we free the rpc_task after the cleanup callbacks
are done in order to avoid a deadlock problem that can be triggered if
the callback needs to wait for another workqueue item to complete.
