Commit 4a94445c (net: Use ip_route_input_noref() in input path)
added a bug in IP defragmentation handling, as non refcounted
dst could escape an RCU protected section.

Commit 64f3b9e2 (net: ip_expire() must revalidate route) fixed
the case of timeouts, but not the general problem.

Tom Parkin noticed crashes in UDP stack and provided a patch,
but further analysis permitted us to pinpoint the root cause.

Before queueing a packet into a frag list, we must drop its dst,
as this dst has limited lifetime (RCU protected)

When/if a packet is finally reassembled, we use the dst of the very
last skb, still protected by RCU and valid, as the dst of the
reassembled packet.

Use same logic in IPv6, as there is no need to hold dst references.

mvneta_tx() was using a static tx queue number causing crashes as
soon as a little bit of traffic was sent via the interface, because
it is normally expected that the same queue should be used as in
dev_queue_xmit().

As suggested by Ben Hutchings, let's use skb_get_queue_mapping() to
get the proper Tx queue number, and use alloc_etherdev_mqs() instead
of alloc_etherdev_mq() to create the queues.

Both my Mirabox and my OpenBlocks AX3 used to crash without this patch
and don't anymore with it. The issue appeared in 3.8 but became more
visible after the fix allowing GSO to be enabled.

Original work was done by Dmitri Epshtein and Thomas Petazzoni. I
just adapted it to take care of Ben's comments.

The mvmdio driver uses the phylib API, so it should select the PHYLIB
symbol, otherwise, a build with mvmdio (but without mvneta) fails to
build with undefined symbols such as mdiobus_unregister, mdiobus_free,
etc.

The mvneta driver does not use the phylib API directly, so it does not
need to select PHYLIB. It already selects the mvmdio driver anyway.

Historically, this problem is due to the fact that the PHY handling
was originally part of mvneta, and was later moved to a separate
driver, without updating the Kconfig select statements
accordingly. And since there was no functional reason to use mvmdio
without mvneta, this case was not tested.

mrp_pdu_queue() should ways be called with the applicant spin lock.
mrp_uninit_applicant() only holds the rtnl lock which is not enough;
a race is possible because mrp_rcv() is called in BH context:

====================
here's another fix for the v3.9 release cycle, if not too late:

Christoph Fritz fixed the device tree property handling on little endian
systems in the sja1000 device tree driver. It was Mylene Josserand who noticed
that the mcp251x spi CAN driver cannot request its interrupt anymore, as the
driver is using a threaded interrupt handler without a primary one and without
specifying IRQF_ONESHOT (which is needed since v3.5). A patch by me fixes this
problem.

To get correct endianes on little endian cpus (like arm) while reading device
tree properties, this patch replaces of_get_property() with
of_property_read_u32(). While there use of_property_read_bool() for the

If a TCP retransmission gets partially ACKed and collapsed multiple
times it is possible for the headroom to grow beyond 64K which will
overflow the 16bit skb->csum_start which is based on the start of
the headroom. It has been observed rarely in the wild with IPoIB due
to the 64K MTU.

Verify if the acking and collapsing resulted in a headroom exceeding
what csum_start can cover and reallocate the headroom if so.

In commit 471cb5a3 ("bonding: remove
usage of dev->master") a bug was introduced which causes a NULL pointer
dereference. If a bond device is in mode 6 (ALB) and a slave is added
it will dereference a NULL pointer in bond_slave_netdev_event().
This is because in bond_enslave we have bond_alb_init_slave() which
changes the MAC address of the slave and causes a NETDEV_CHANGEADDR.
Then we have in bond_slave_netdev_event():
        struct slave *slave = bond_slave_get_rtnl(slave_dev);
        struct bonding *bond = slave->bond;
bond_slave_get_rtnl() dereferences slave_dev->rx_handler_data which at
that time is NULL since netdev_rx_handler_register() is called later.

This is fixed by checking if slave is NULL before dereferencing it.

The cnic module is responsible for initializing various bnx2x structs
via callbacks provided by the bnx2x module.
One such struct is the queue object for the FCoE queue.

If a device is working in AFEX mode and its configuration allows FCoE yet
the cnic module is not loaded, it's very likely a null pointer dereference
will occur, as the bnx2x will erroneously access the FCoE's queue object.

Prevent said access until cnic properly registers itself.

Pull another nfs fixlet from Trond Myklebust:
 "I suddenly noticed that a one-line issue that I _thought_ I had fixed
  with the nfs41_walk_client_list patch was apparently still there in
  the pull request I sent earlier today.  I'm very sorry for not
  catching that in time.

   - Fix a brain fart in nfs41_walk_client_list"

* tag 'nfs-for-3.9-5' of git://git.linux-nfs.org/projects/trondmy/linux-nfs:
  NFSv4: Doh! Typo in the fix to nfs41_walk_client_list

Make sure that we set the status to 0 on success. Missed in testing
because it never appears when doing multiple mounts to _different_
servers.

This change properly enables the "requester" in G200ER cards that is
responsible for getting pixels out of memory and clocking them out to
the screen.

arch_local_irq_save() and friends are required to act as compiler
memory barriers. This patch adds a "memory" clobber to the inline
asm code in arch_local_irq_restore() which is used as the building
block for other functions needing to set/clear the interrupt enable
in the CSR register.

Pull block fixes from Jens Axboe:
 "I've got a few smaller fixes queued up for 3.9 that should go in.  The
  major one is the loop regression, the others are nice fixes on their
  own though.  It contains:

   - Fix for unitialized var in the block sysfs code, courtesy of Arnd
     and gcc-4.8.

   - Two fixes for mtip32xx, fixing probe and command timeout.  Also a
     debug measure that could have waited for 3.10, but it's driver
     only, so I let it slip in.

   - Revert the loop partition cleanup fix, it could cause a deadlock on
     auto-teardown as part of umount.  The fix is clear, but at this
     point we just want to revert it and get a real fix in for 3.10."
