Pull networking fixes from David Miller:

 1) If the local_df boolean is set on an SKB we have to allocate a
    unique ID even if IP_DF is set in the ipv4 headers, from Ansis
    Atteka.

 2) Some fixups for the new chipset support that went into the sfc
    driver, from Ben Hutchings.

 3) Because SCTP bypasses a good chunk of, and actually duplicates, the
    logic of the ipv6 output path, some IPSEC things don't get done
    properly.  Integrate SCTP better into the ipv6 output path so that
    these problems are fixed and such issues don't get missed in the
    future either.  From Daniel Borkmann.

 4) Fix skge regressions added by the DMA mapping error return checking
    added in v3.10, from Mikulas Patocka.

 5) Kill some more IRQF_DISABLED references, from Michael Opdenacker.

 6) Fix races and deadlocks in the bridging code, from Hong Zhiguo.

 7) Fix error handling in tun_set_iff(), in particular don't leak
    resources.  From Jason Wang.

 8) Prevent format-string injection into xen-netback driver, from Kees
    Cook.

 9) Fix regression added to netpoll ARP packet handling, in particular
    check for the right ETH_P_ARP protocol code.  From Sonic Zhang.

10) Try to deal with AMD IOMMU errors when using r8169 chips, from
    Francois Romieu.

11) Cure freezes due to recent changes in the rt2x00 wireless driver,
    from Stanislaw Gruszka.

12) Don't do SPI transfers (which can sleep) in interrupt context in
    cw1200 driver, from Solomon Peachy.

13) Fix LEDs handling bug in 5720 tg3 chips already handled for 5719.
    From Nithin Sujir.

14) Make xen_netbk_count_skb_slots() count the actual number of slots
    that will be used, taking into consideration packing and other
    issues that the transmit path will run into.  From David Vrabel.

15) Use the correct maximum age when calculating the bridge
    message_age_timer, from Chris Healy.

16) Get rid of memory leaks in mcs7780 IRDA driver, from Alexey
    Khoroshilov.

17) Netfilter conntrack extensions were converted to RCU but are not
    always freed properly using kfree_rcu().  Fix from Michal Kubecek.

18) VF reset recovery not being done correctly in qlcnic driver, from
    Manish Chopra.

19) Fix inverted test in ATM nicstar driver, from Andy Shevchenko.

20) Missing workqueue destroy in cxgb4 error handling, from Wei Yang.

21) Internal switch not initialized properly in bgmac driver, from Rafał
    Miłecki.

22) Netlink messages report wrong local and remote addresses in IPv6
    tunneling, from Ding Zhi.

23) ICMP redirects should not generate socket errors in DCCP and SCTP.
    We're still working out how this should be handled for RAW and UDP
    sockets.  From Daniel Borkmann and Duan Jiong.

24) We've had several bugs wherein the network namespace's loopback
    device gets accessed after it is free'd, NULL it out so that we can
    catch these problems more readily.  From Eric W Biederman.

25) Fix regression in TCP RTO calculations, from Neal Cardwell.

26) Fix too early free of xen-netback network device when VIFs still
    exist.  From Paul Durrant.

commit b9871bcfd2
    bnx2x: VF RSS support - PF side

changed the configuration of the doorbell HW and it broke iSCSI and FCoE.
We fix this by making compatible changes to the doorbell address in bnx2i
and bnx2fc.  For the userspace driver, we need to pass a modified CID
so that the existing userspace driver will calculate the correct doorbell
address and continue to work.

48efe453e6 Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
 "Lots of activity again this round for I/O performance optimizations
  (per-cpu IDA pre-allocation for vhost + iscsi/target), and the
  addition of new fabric independent features to target-core
  (COMPARE_AND_WRITE + EXTENDED_COPY).

  The main highlights include:

   - Support for iscsi-target login multiplexing across individual
     network portals
   - Generic Per-cpu IDA logic (kent + akpm + clameter)
   - Conversion of vhost to use per-cpu IDA pre-allocation for
     descriptors, SGLs and userspace page pointer list
   - Conversion of iscsi-target + iser-target to use per-cpu IDA
     pre-allocation for descriptors
   - Add support for generic COMPARE_AND_WRITE (AtomicTestandSet)
     emulation for virtual backend drivers
   - Add support for generic EXTENDED_COPY (CopyOffload) emulation for
     virtual backend drivers.
   - Add support for fast memory registration mode to iser-target (Vu)

  The patches to add COMPARE_AND_WRITE and EXTENDED_COPY support are of
  particular significance, which make us the first and only open source
  target to support the full set of VAAI primitives.

  Currently Linux clients are lacking upstream support to actually
  utilize these primitives.  However, with server side support now in
  place for folks like MKP + ZAB working on the client, this logic once
  reserved for the highest end of storage arrays, can now be run in VMs
  on their laptops"

that value to scsi mid-layer.

Issue was seen when SCSI buffer address is more than 40 bits in system
with more than 1.1TB RAM. When SCSI buffer is passed to VIC, it is failing
to map to correct buffer address, as DMA mask is set to 40 bits in driver
initialization. Corrected DMA_MASK from 40-bits to 64-bits to avoid masking
41-64 bits addresses.

This patch fixes an out-of-bounds error in sd_read_cache_type(), found
by Google's AddressSanitizer tool.  When the loop ends, we know that
"offset" lies beyond the end of the data in the buffer, so no Caching
mode page was found.  In theory it may be present, but the buffer size
is limited to 512 bytes.

163dbcd89c [SCSI] hpsa: housekeeping patch for device_id and product arrays
This patch does a bit of housekeeping for hpsa. Change lowercase alpha hex
digits to uppercase for consistency within the driver. Also moves the P822se
in the tables to keep controllers of each family grouped together.

7d568652d3 [SCSI] ufs: fix the setting interrupt aggregation counter
IACTH(Interrupt aggregation counter threshold) value is allowed
up to 0x1F and current setting value is the maximum.
This value is related with NUTRS(max:0x20) of HCI's capability.
Considering HCI controller doesn't support the maximum, IACTH
setting should be adjusted with possible value.
For that, existing 'ufshcd_config_int_aggr' is split into two part
[reset, configure].

sense data isn't obvious. So, in this case the Data Segment Length
field should be checked. If a non-zero value, it means that UPIU
has Sense Data in the Data Segment area.
