40GbE Intel Wired LAN Driver Updates 2017-02-18

This series contains updates to i40e and i40evf only.

Alan fixes a bug in which the driver is unable to exit overflow
promiscuous mode after having added "too many" mac filters.  Ractored
the '%*ph' printk format specifier to instead use the print_hex_dump().

Josh adds enabling multicast magic packet wakeup by adding calls to
the mac_address_write admin q function during power down to update the
PRTPM_SAH/SAL registers with the MC_MAG_EN bit.

Jake remove a duplicate call i40e_update_link_info(), since it does not
need to call it twice.  Fixes and issue where we calculating the wrong
switch id on big endian platforms.  Avoided sparse warning, by doing a
typecast to ensure the value is of the type expected by
csum_replace_by_diff().

Mitch fixes a memory leak by freeing resources during i40e_remove().
Cleans up some code confusion by adding a proper code comment.

Resizing currently drops consumer lock.  This can cause entries to be
reordered, which isn't good in itself.  More importantly, consumer can
detect a false ring empty condition and block forever.

Further, nesting of consumer within producer lock is problematic for
tun, since it produces entries in a BH, which causes a lock order
reversal:

       CPU0                    CPU1
       ----                    ----
  consume:
  lock(&(&r->consumer_lock)->rlock);
                               resize:
                               local_irq_disable();
                               lock(&(&r->producer_lock)->rlock);
                               lock(&(&r->consumer_lock)->rlock);
  <Interrupt>
  produce:
  lock(&(&r->producer_lock)->rlock);

To fix, nest producer lock within consumer lock during resize,
and keep consumer lock during the whole swap operation.

sctp: support MSG_MORE flag when sending msg

This patch is to add support for MSG_MORE on sctp. Patch 1/2 is an
improvement ahead of patch 2/2 to solve the close block problem
mentioned in https://patchwork.ozlabs.org/patch/372404/.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch is to add support for MSG_MORE on sctp.

It adds force_delay in sctp_datamsg to save MSG_MORE, and sets it after
creating datamsg according to the send flag. sctp_packet_can_append_data
then uses it to decide if the chunks of this msg will be sent at once or
delay it.

Note that unlike [1], this patch saves MSG_MORE in datamsg, instead of
in assoc. As sctp enqueues the chunks first, then dequeue them one by
one. If it's saved in assoc,the current msg's send flag (MSG_MORE) may
affect other chunks' bundling.

Since last patch, sctp flush out queue once assoc state falls into
SHUTDOWN_PENDING, the close block problem mentioned in [1] has been
solved as well.

This patch is to flush out queue when assoc state falls into
SHUTDOWN_PENDING if there are still chunks in it, so that the
data can be sent out as soon as possible before sending SHUTDOWN
chunk.

When sctp supports MSG_MORE flag in next patch, this improvement
can also solve the problem that the chunks with MSG_MORE flag
may be stuck in queue when closing an assoc.

There are number of function calls, originating from user-space,

sctp has changed to use rhlist for transport rhashtable since commit
7fda702f ("sctp: use new rhlist interface on sctp transport
rhashtable").

But rhltable_insert_key doesn't check the duplicate node when inserting
a node, unlike rhashtable_lookup_insert_key. It may cause duplicate
assoc/transport in rhashtable. like:

 client (addr A, B)                 server (addr X, Y)
    connect to X           INIT (1)
                        ------------>
    connect to Y           INIT (2)
                        ------------>
                         INIT_ACK (1)
                        <------------
                         INIT_ACK (2)
                        <------------

After sending INIT (2), one transport will be created and hashed into
rhashtable. But when receiving INIT_ACK (1) and processing the address
params, another transport will be created and hashed into rhashtable
with the same addr Y and EP as the last transport. This will confuse
the assoc/transport's lookup.

This patch is to fix it by returning err if any duplicate node exists
before inserting it.

Now when sending a packet, sctp_transport_dst_check will check if dst
is obsolete by calling ipv4/ip6_dst_check. But they return obsolete
only when adding a new cache, after that when the cache's pmtu is
updated again, it will not trigger transport->dst/pmtu's update.

It can be reproduced by reducing route's pmtu twice. At the 1st time
client will add a new cache, and transport->pathmtu gets updated as
sctp_transport_dst_check finds it's obsolete. But at the 2nd time,
cache's mtu is updated, sctp client will never send out any packet,
because transport->pmtu has no chance to update.

This patch is to fix this by also checking if transport pmtu is dst
mtu in sctp_transport_dst_check, so that transport->pmtu can be
updated on time.

sctp: add receiver-side procedures for stream reconf ssn reset request chunk

Patch 3/7 and 4/7 are to implement receiver-side procedures for the
Outgoing and Incoming SSN Reset Request Parameter described in rfc6525
section 5.2.2 and 5.2.3

Patch 1/7 and 2/7 are ahead of them to define some apis.

Patch 5/7-7/7 are to add the process of reconf chunk event in rx path.

Note that with this patchset, asoc->reconf_enable has no chance yet to
be set, until the patch "sctp: add get and set sockopt for reconf_enable"
is applied in the future. As we can not just enable it when sctp is not
capable of processing reconf chunk yet.

v1->v2:
  - re-split the patchset and make sure it has no dead codes for review.
  - rename the titles of the commits and improve some changelogs.
  - drop __packed from some structures in patch 1/7.
  - fix some kbuild warnings in patch 3/7 by initializing str_p = NULL.
  - sctp_chunk_lookup_strreset_param changes to return sctp_paramhdr_t *
    and uses sctp_strreset_tsnreq to access request_seq in patch 3/7.
  - use __u<size> in uapi sctp.h in patch 1/7.
  - do str_list endian conversion when generating stream_reset_event in patch
    2/7.
  - remove str_list endian conversion, pass resp_seq param with network endian
    to lookup_strreset_param in 3/7.
  - move str_list endian conversion out of sctp_make_strreset_req, so that
    sctp_make_strreset_req can be used more conveniently to process inreq in
    patch 4/7.
  - remove sctp_merge_reconf_chunk and not support response with multiparam
