      Pull SCSI fixes from James Bottomley:
 "This is a couple of small fixes: one is a potential uninitialised
  error variable in the alua code, potentially causing spurious failures
  and the other is a problem caused by the conversion of SCSI to
  hostwide tags which resulted in the qla1280 driver always failing in
  host initialisation"

      Jiri Benc authored 
      For ipgre interface in collect metadata mode, it doesn't make sense for the
interface to be of ARPHRD_IPGRE type. The outer header of received packets
is not needed, as all the information from it is present in metadata_dst. We
already don't set ipgre_header_ops for collect metadata interfaces, which is
the only consumer of mac_header pointing to the outer IP header.

Just set the interface type to ARPHRD_NONE in collect metadata mode for
ipgre (not gretap, that still correctly stays ARPHRD_ETHER) and reset
mac_header.

Fixes: a64b04d8 ("gre: do not assign header_ops in collect metadata mode")
Fixes: 2e15ea39 ("ip_gre: Add support to collect tunnel metadata.")

      openvswitch: Fix cached ct with helper. · 16ec3d4f
      Joe Stringer authored 
      When using conntrack helpers from OVS, a common configuration is to
perform a lookup without specifying a helper, then go through a
firewalling policy, only to decide to attach a helper afterwards.

In this case, the initial lookup will cause a ct entry to be attached to
the skb, then the later commit with helper should attach the helper and
confirm the connection. However, the helper attachment has been missing.
If the user has enabled automatic helper attachment, then this issue
will be masked as it will be applied in init_conntrack(). It is also
masked if the action is executed from ovs_packet_cmd_execute() as that
will construct a fresh skb.

This patch fixes the issue by making an explicit call to try to assign
the helper if there is a discrepancy between the action's helper and the
current skb->nfct.

Fixes: cae3a262 ("openvswitch: Allow attaching helpers to ct action")

      x86/extable: ensure entries are swapped completely when sorting · 50c73890
      Mathias Krause authored 
      The x86 exception table sorting was changed in commit 29934b0f
("x86/extable: use generic search and sort routines") to use the arch
independent code in lib/extable.c.  However, the patch was mangled
somehow on its way into the kernel from the last version posted at [1].
The committed version kind of attempted to incorporate the changes of
commit 548acf19 ("x86/mm: Expand the exception table logic to allow
new handling options") as in _completely_ _ignoring_ the x86 specific
'handler' member of struct exception_table_entry.  This effectively
broke the sorting as entries will only partly be swapped now.

Fortunately, the x86 Kconfig selects BUILDTIME_EXTABLE_SORT, so the
exception table doesn't need to be sorted at runtime. However, in case
that ever changes, we better not break the exception table sorting just
because of that.

[ Ard Biesheuvel points out that BUILDTIME_EXTABLE_SORT applies to the
  core image only, but we still rely on the sorting routines for modules
  in that case - Linus ]

Fix this by providing a swap_ex_entry_fixup() macro that takes care of
the 'handler' member.

      Jamal Hadi Salim says:

====================
Some actions were broken in allowing for late binding of actions.
Late binding workflow is as follows:
a) create an action and provide all necessary parameters for it
Optionally provide an index or let the kernel give you one.
Example:
sudo tc actions add action police rate 1kbit burst 90k drop index 1

b) later on bind to the pre-created action from a filter definition
by merely specifying the index.
Example:
sudo tc filter add dev lo parent ffff: protocol ip prio 8 \
u32 match ip src 127.0.0.8/32 flowid 1:8 action police index 1
