Xin Long a83863174a sctp: prepare asoc stream for stream reconf
sctp stream reconf, described in RFC 6525, needs a structure to
save per stream information in assoc, like stream state.

In the future, sctp stream scheduler also needs it to save some
stream scheduler params and queues.

This patchset is to prepare the stream array in assoc for stream
reconf. It defines sctp_stream that includes stream arrays inside
to replace ssnmap.

Note that we use different structures for IN and OUT streams, as
the members in per OUT stream will get more and more different
from per IN stream.

v1->v2:
  - put these patches into a smaller group.
v2->v3:
  - define sctp_stream to contain stream arrays, and create stream.c
    to put stream-related functions.
  - merge 3 patches into 1, as new sctp_stream has the same name
    with before.

Eric Garver df560056d9 udp: inuse checks can quit early for reuseport
UDP lib inuse checks will walk the entire hash bucket to check if the
portaddr is in use. In the case of reuseport we can stop searching when
we find a matching reuseport.

On a 16-core VM a test program that spawns 16 threads that each bind to
1024 sockets (one per 10ms) takes 1m45s. With this change it takes 11s.

Also add a cond_resched() when the port is not specified.

Linus Torvalds 308c470bc4 sound fixes for 4.10-rc3
Nothing particular stands out, only a few small fixes for USB-audio,
 HD-audio and Firewire.  The USB-audio fix is the respin of the
 previous race fix after a revert due to the regression.

1GbE Intel Wired LAN Driver Updates 2017-01-06

This series contains updates/fixes to igb and e1000e.

Joe fixes indentation and improper line wrapping in igb.

David Singleton fixes an issue in e1000e where in systemd, where things
are done in parallel and can create a condition where e1000_shutdown is
called after e1000_close, hitting BUG_ON assert in free_msi_irqs.

Cao Jin fixes a code comment on the wakeup status register.  Also fixes
a possible NULL pointer dereference by using igb_adapter->io_addr
instead of e1000_hw->hw_addr in igb_configure_tx_ring().

Chris Arges works around a firmware issue, which can cause probe of i210
NIC to fail, so zero the page select register during igb_get_phy_id() to
workaround the issue.  Aaron Sierra adds also a check for this issue
during the initialization of PHY parameters to ensure that this same
issue happens after probe.

Todd fixes a possible race condition in close/suspend by extending
the rtnl_lock() to protect the call to netif_device_detach() and
igb_clear_interrupt_scheme().  Also adds i211 to a known i210/i211
workaround.

Hannu Lounento fixes inverted logic on a debug statement.

Hariprasad Shenai 4055ae5e6d cxgb4: Synchronize access to mailbox
The issue comes when there are multiple threads attempting to use
the mailbox facility at the same time.
When DCB operations and interface up/down is run in a loop for every
0.1 sec, we observed mailbox collisions. And out of the two commands
one would fail with the present code, since we don't queue the second
command.

To overcome the above issue, added a queue to access the mailbox.
Whenever a mailbox command is issued add it to the queue. If its at
the head issue the mailbox command, else wait for the existing command
to complete. Usually command takes less than a milli-second to
complete.

Also timeout from the loop, if the command under execution takes
long time to run.

In reality, the number of mailbox access collisions is going to be
very rare since no one runs such abusive script.

Grygorii Strashko 5ca7d1ca77 net: phy: dp83867: fix irq generation
For proper IRQ generation by DP83867 phy the INT/PWDN pin has to be
programmed as an interrupt output instead of a Powerdown input in
Configuration Register 3 (CFG3), Address 0x001E, bit 7 INT_OE = 1. The
current driver doesn't do this and as result IRQs will not be generated by
DP83867 phy even if they are properly configured in DT.

Hence, fix IRQ generation by properly configuring CFG3.INT_OE bit and
ensure that Link Status Change (LINK_STATUS_CHNG_INT) and Auto-Negotiation
Complete (AUTONEG_COMP_INT) interrupt are enabled. After this the DP83867
driver will work properly in interrupt enabled mode.

So they can figure out what is the optimal number of pages
that can be contingously stitched together without fear of
bounce buffer.

We also expose an mechanism for sub-users of SWIOTLB API, such
as Xen-SWIOTLB to set the max segment value. And lastly
if swiotlb=force is set (which mandates we bounce buffer everything)
we set max_segment so at least we can bounce buffer one 4K page
instead of a giant 512KB one for which we may not have space.

Similar to ixgbe, when an interface is part of a namespace it is
possible that igb_close() may be called while __igb_shutdown() is

Extend the rtnl_lock() to protect the call to netif_device_detach() and
igb_clear_interrupt_scheme() in __igb_shutdown() and check for
netif_device_present() to avoid calling igb_clear_interrupt_scheme() a

Guilherme G Piccoli 69b97cf6db igb: re-assign hw address pointer on reset after PCI error
Whenever the igb driver detects the result of a read operation returns
a value composed only by F's (like 0xFFFFFFFF), it will detach the
net_device, clear the hw_addr pointer and warn to the user that adapter's
link is lost - those steps happen on igb_rd32().

In case a PCI error happens on Power architecture, there's a recovery
mechanism called EEH, that will reset the PCI slot and call driver's
handlers to reset the adapter and network functionality as well.

We observed that once hw_addr is NULL after the error is detected on
igb_rd32(), it's never assigned back, so in the process of resetting
the network functionality we got a NULL pointer dereference in both
igb_configure_tx_ring() and igb_configure_rx_ring(). In order to avoid
such bug, this patch re-assigns the hw_addr value in the slot_reset
handler.

Resetting the PHY before reading from it, ensures the page select
register is in its default state and doesn't make assumptions about
the PHY's register set before the PHY has been probed.

Cao jin 629823b872 igb: use igb_adapter->io_addr instead of e1000_hw->hw_addr
When running as guest, under certain condition, it will oops as following.
writel() in igb_configure_tx_ring() results in oops, because hw->hw_addr
is NULL. While other register access won't oops kernel because they use
wr32/rd32 which have a defense against NULL pointer.

Chris J Arges 4e684f59d7 igb: Workaround for igb i210 firmware issue
Sometimes firmware may not properly initialize I347AT4_PAGE_SELECT causing
the probe of an igb i210 NIC to fail. This patch adds an addition zeroing
of this register during igb_get_phy_id to workaround this issue.

Thanks for Jochen Henneberg for the idea and original patch.

khalidm 7e54d9d063 e1000e: driver trying to free already-free irq
During systemd reboot sequence network driver interface is shutdown
by e1000_close. The PCI driver interface is shut by e1000_shutdown.
The e1000_shutdown checks for netif_running status, if still up it
brings down driver. But it disables msi outside of this if statement,
regardless of netif status. All this is OK when e1000_close happens
after shutdown. However, by default, everything in systemd is done
in parallel. This creates a conditions where e1000_shutdown is called
after e1000_close, therefore hitting BUG_ON assert in free_msi_irqs.

Sowmini Varadhan c1878f7a89 tools: psock_tpacket: block Rx until socket filter has been added and socket has been bound to loopback.
Packets from any/all interfaces may be queued up on the PF_PACKET socket
before it is bound to the loopback interface by psock_tpacket, and
when these are passed up by the kernel, they could interfere
with the Rx tests.

Avoid interference from spurious packet by blocking Rx until the
socket filter has been set up, and the packet has been bound to the
desired (lo) interface. The effective sequence is
	socket(PF_PACKET, SOCK_RAW, 0);
	set up ring
	Invoke SO_ATTACH_FILTER
	bind to sll_protocol set to ETH_P_ALL, sll_ifindex for lo
After this sequence, the only packets that will be passed up are
those received on loopback that pass the attached filter.

Soheil Hassas Yeganeh ad02c4f547 tcp: provide timestamps for partial writes
For TCP sockets, TX timestamps are only captured when the user data
is successfully and fully written to the socket. In many cases,
however, TCP writes can be partial for which no timestamp is
collected.

Collect timestamps whenever any user data is (fully or partially)
copied into the socket. Pass tcp_write_queue_tail to tcp_tx_timestamp
instead of the local skb pointer since it can be set to NULL on
the error path.

Note that tcp_write_queue_tail can be NULL, even if bytes have been
copied to the socket. This is because acknowledgements are being
processed in tcp_sendmsg(), and by the time tcp_tx_timestamp is
called tcp_write_queue_tail can be NULL. For such cases, this patch
does not collect any timestamps (i.e., it is best-effort).

This patch is written with suggestions from Willem de Bruijn and
Eric Dumazet.

Change-log V1 -> V2:
	- Use sockc.tsflags instead of sk->sk_tsflags.
	- Use the same code path for normal writes and errors.
