[SCSI] megaraid_sas: Dont load DevHandle unless FastPath enabled

The following patch for megaraid_sas will fix an issue where the
driver should not be loading the DevHandle unless FastPath is enabled.
 If FastPath was not enabled, this means the hardware raid map
validation failed for some reason, or the map was corrupted, which
could mean the DevHandle could be invalid.

[SCSI] qla2xxx: Don't process RSCNs for a vport on the same physical adapter.

Currently,the driver is processes RSCNs for each new NPIV ports that is created.
Processing the RSCN includes a name server query to see what has changed at the
name server side.  The name server query is performed by the physical port and
each virtual port on the physical adapter (since the RSCN is passed to each
virtual port for processing).  As the number of virtual ports being created
increases, this causes a lot of traffic and busies the firmware.

Processing the RSCN for a virtual port we already have a priori knowledge of is
not necessary so check the 24-bit fabric ID of the RSCN entry and skip
processing it if the RSCN is for a virtual port we already know about.

[SCSI] qla2xxx: silence two GCC warnings.

Compiling qla_gs.o (part of the qla2xxx module) triggers two GCC
warnings:
    drivers/scsi/qla2xxx/qla_gs.c: In function ‘qla2x00_fdmi_rhba’:
    drivers/scsi/qla2xxx/qla_gs.c:1339:7: warning: array subscript is above array bounds [-Warray-bounds]
    drivers/scsi/qla2xxx/qla_gs.c: In function ‘qla2x00_fdmi_register’:
    drivers/scsi/qla2xxx/qla_gs.c:1663:15: warning: array subscript is above array bounds [-Warray-bounds]

It seems that the sequence of a strcpy followed by a strlen confuses GCC
when it is keeping track of array bounds here. (It is not clear to me
which array triggers this warning and by how much GCC thinks the
subscript is above its bounds. Neither is it clear to me why comparable
code in these two functions doesn't trigger this warning.)

An easy way to silence these warnings is to use preprocessor macros and
strncpy, as that apparently gives GCC enough information to keep track
of array bounds.

[SCSI] qla2xxx: Extra loopback error handling for ISP83xx.

Add the following error handling for loopback diagnostic mode with ISP83xx:

1. If we do not receive an MBA_DCBX_COMPLETE after our initial set port
configuration command, try to reset the port back into normal operation.
If that fails, take a FCoE dump and then reset the chip.
2. After completing the loopback diagnostic operation, if the reset of the port
back into normal operation fails then reset the port so we take a FCoE dump
and then reset the chip.
3. When we receive an IDC notification and the requested operation is loopback
extend the loop down timer so the link does not appear to down for an
extended period of time.

[SCSI] qla2xxx: Correct race in loop_state assignment during reset handling.

There's a subtle race in the loop/bus-reset handling whereby a
VHA's loop-state can get incorrectly set to 'down' after the
loop-reset and firmware's completion of link re-negotiation.  The
original code incorrectly assumes that firmware AENs would arrive
only after mailbox-command execution to initiate the link-flap.

Here's a good case with the old code (AENs arrive after
mailbox-command completion):

[SCSI] qla4xxx: Re-register IRQ handler while retrying initialize of adapter

Problem:
If initialization of adapter fails for some reason, then the interrupt handlers
are released. The interrupt handlers are not registered again when initialization
of adapter is retried.

Solution:
Re-register the interrupt handler when adapter initialization is retried.

[SCSI] cxgb4i: Remove the scsi host device when removing device

When doing a hotplug remove of a cxgb4 device, there are still dandling
symlinks at /sys/class/scsi_host/hostX to the removed PCI device. The
upper layer device may also try to send data, which may crash the
system.

The DETACH message from the lower level driver is sent to the ULD when
the device is removed, when the scsi host should be removed from the
system, avoiding any problems.

After this patch, there are no more dangling symlinks and many attempts
to crash the system while there is SCSI activity and removing the device
have failed. Adding the device back again works as expected, with the
scsi hosts showing up again.

Based on a patch by Karen Xie.

[SCSI] qla4xxx: Fix MBOX intr switching from polling to intr mode for ISP83XX

Issue:
Mailbox command timed out after switching from polling mode to interrupt mode.

Events:-
 1. Mailbox interrupts are disabled
 2. FW generates AEN and at same time driver enables Mailbox Interrupt
 3. Driver issues new mailbox to Firmware

In above case driver will not get AEN interrupts generated by FW in step #2 as
FW generated this AEN when interrupts are disabled. During the same time
driver enabled the mailbox interrupt, so driver will not poll for interrupt.
Driver will never process AENs generated in step #2 and issues new mailbox to
FW, but now FW is not able to post mailbox completion as AENs generated before
are not processed by driver.

Fix:
Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX.
This will make sure we process all Mailbox and AENs in interrupt mode.

[SCSI] gdth: Remove buggy ROM handling

The ROM address handling in gdth_init_pci() is useless and possibly
dangerous.  This patch removes it.

"pci_resource_start(pdev, 8)" is not well-defined.  PCI resources 0-5 are
standard PCI BARs and 6 is the expansion ROM.  Resource 8 is either an
SR-IOV BAR (if CONFIG_PCI_IOV=y, resources 7-12 are SR-IOV BARs) or a
bridge window (resources 7-10).

The GDT device is neither an SR-IOV device nor a bridge, so in either case
resource 8 should be zero since struct pci_dev is allocated with kzalloc().

It is illegal for a driver to write an arbitrary address to the ROM BAR
because it has no way of knowing whether the ROM will conflict with another
device.

I think the only effect of the code being removed was to:

  1) Enable the ROM at 0xFEFF0000 (possibly causing a conflict with
     another device)
  2) Delay one millisecond

I doubt the delay is needed, but I left it since it seems innocuous.

  problem which might cause the IOMMU to stop working under high load

Merge git://git./linux/kernel/git/davem/net

Pull networking updates from David Miller:
 "Much more accumulated than I would have liked due to an unexpected
  bout with a nasty flu:

   1) AH and ESP input don't set ECN field correctly because the
      transport head of the SKB isn't set correctly, fix from Li
      RongQing.

   2) If netfilter conntrack zones are disabled, we can return an
      uninitialized variable instead of the proper error code.  Fix from
      Borislav Petkov.

   3) Fix double SKB free in ath9k driver beacon handling, from Felix
      Feitkau.

   4) Remove bogus assumption about netns cleanup ordering in
      nf_conntrack, from Pablo Neira Ayuso.

   5) Remove a bogus BUG_ON in the new TCP fastopen code, from Eric
      Dumazet.  It uses spin_is_locked() in it's test and is therefore
      unsuitable for UP.

   6) Fix SELINUX labelling regressions added by the tuntap multiqueue
      changes, from Paul Moore.

   7) Fix CRC errors with jumbo frame receive in tg3 driver, from Nithin
      Nayak Sujir.

   8) CXGB4 driver sets interrupt coalescing parameters only on first
      queue, rather than all of them.  Fix from Thadeu Lima de Souza
      Cascardo.

   9) Fix regression in the dispatch of read/write registers in dm9601
      driver, from Tushar Behera.

  10) ipv6_append_data miscalculates header length, from Romain KUNTZ.

  11) Fix PMTU handling regressions on ipv4 routes, from Steffen
      Klassert, Timo Teräs, and Julian Anastasov.

  12) In 3c574_cs driver, add necessary parenthesis to "x << y & z"
      expression.  From Nickolai Zeldovich.

  13) macvlan_get_size() causes underallocation netlink message space,
      fix from Eric Dumazet.

  14) Avoid division by zero in xfrm_replay_advance_bmp(), from Nickolai
      Zeldovich.  Amusingly the zero check was already there, we were
      just performing it after the modulus :-)

  15) Some more splice bug fixes from Eric Dumazet, which fix things
      mostly eminating from how we now more aggressively use high-order
      pages in SKBs.

  16) Fix size calculation bug when freeing hash tables in the IPSEC
      xfrm code, from Michal Kubecek.

  17) Fix PMTU event propagation into socket cached routes, from Steffen
      Klassert.

  18) Fix off by one in TX buffer release in netxen driver, from Eric
      Dumazet.

  19) Fix rediculous memory allocation requirements introduced by the
      tuntap multiqueue changes, from Jason Wang.

  20) Remove bogus AMD platform workaround in r8169 driver that causes
      major problems in normal operation, from Timo Teräs.

  21) virtio-net set affinity and select queue don't handle
      discontiguous cpu numbers properly, fix from Wanlong Gao.

  22) Fix a route refcounting issue in loopback driver, from Eric
      Dumazet.  There's a similar fix coming that we might add to the
      macvlan driver as well.

  23) Fix SKB leaks in batman-adv's distributed arp table code, from
      Matthias Schiffer.

  24) r8169 driver gives descriptor ownership back the hardware before
      we're done reading the VLAN tag out of it, fix from Francois
      Romieu.

  25) Checksums not calculated properly in GRE tunnel driver fix from
      Pravin B Shelar.

26) Fix SCTP memory leak on namespace exit."
