bnx2x: Create workqueue for IOV related tasks

The bnx2x sriov mechanisms were done in the bnx2x slowpath workitem which
runs on the bnx2x's workqueue; This workitem is also responsible for the bottom
half of interrupt handling in the driver, and specifically it also receives
FW notifications of ramrod completions, allowing other flows to progress.

The original design of the sriov reltaed-flows was based on the notion such
flows must not sleep, since their context is the slowpath workitem.
Otherwise, we might reach timeouts - those flows may wait for ramrod completion
that will never arrive as the workitem wlll not be re-scheduled until that same
flow will be over.

In more recent time bnx2x started supporting features in which the VF interface
can be configured by the tools accessing the PF on the hypervisor.
This support created possible races on the VF-PF lock (which is taken either
when the PF is handling a VF message or when the PF is doing some slowpath work
on behalf of the VF) which may cause timeouts on the VF side and lags on the PF
side.

This patch changes the scheme - it creates a new workqueue for sriov related
tasks and moves all handling currently done in the slowpath task into the the
new workqueue.

- Support for ISO 15693 a.k.a. NFC vicinity a.k.a. Type 5 tags. ISO
  15693 are long range (1 - 2 meters) vicinity tags/cards. The kernel

- Support for TI's trf7970a chipset. This chipset relies on the NFC
  digital layer and the driver currently supports type 2, 4A and 5 tags.

- Support for NXP's pn544 secure firmare download. The pn544 C3 chipsets
  relies on a different firmware download protocal than the C2 one. We

- Support for 4A tags from the NFC digital layer.

- A bunch of cleanups and minor fixes from Axel Lin and Thierry Escande."

For the iwlwifi bits, Emmanuel says:

"We were sending a host command while the mutex wasn't held. This
led to hard-to-catch races."

And...

"I have a fix for a "merge damage" which is not really a merge
damage: it enables scheduled scan which has been disabled in
wireless.git. Since you merged wireless.git into wireless-next.git,
this can now be fixed in wireless-next.git.

Besides this, Alex made a workaround for a hardware bug. This fix
allows us to consume less power in S3. Arik and Eliad continue to
work on D0i3 which is a run-time power saving feature. Eliad also

own contribution. Avri dives deep in the power code - newer firmware
will allow to enable power save in newer scenarios. Johannes made a few
clean-ups. I have the regular amount of BT Coex boring stuff. I disable
uAPSD since we identified firmware bugs that cause packet loss. One
thing that do stand out is the udev event that we now send when the
FW asserts. I hope it will allow us to debug the FW more easily."

Also included is one last iwlwifi pull for a build breakage fix...

For the Atheros bits, Kalle says:

"Michal now did some optimisations and was able to improve throughput by
100 Mbps on our MIPS based AP135 platform. Chun-Yeow added some
workarounds to be able to better use ad-hoc mode. Ben improved log
messages and added support for MSDU chaining. And, as usual, also some
smaller fixes."

Beyond that...

Andrea Merello continues his rtl8180 refactoring, in preparation for
a long-awaited rtl8187 driver.  We get a new driver (rsi) for the
RS9113 chip, from Fariya Fatima.  And, of course, we get the usual
round of updates for ath9k, brcmfmac, mwifiex, wil6210, etc. as well.

Using dev_kfree/consume_skb_any for functions called in multiple contexts

These changes are a result of walking through the network drivers
supporting netpoll and verifying the code paths that netpoll can cause
to be called in hard irq context use an appropriate flavor of
kfree_skb.  Either dev_kfree_skb_any or dev_consume_skb_any.

Since my last pass at this I have become aware of the small differences
between dev_kfree_skb_any and dev_consume_skb_any.
net/core/drop_monitor.c reports the dev_kfree_skb_any as a drop and
while being quite about the second.  With the weird twist that
dev_kfree_skb is unintuitively consume_skb.

As netpoll now calls the napi poll function with budget == 0, pieces of
a drivers the napi poll function that don't run when budget == 0 have
been ignored.

The most interesting change is to the atl1c which tried unsuccesfully to
tell one of it's functions which context it is called in so that it
could call dev_kfree_skb_irq or dev_kfree_skb as appropriate.  I have
just removed the extra parameter and called dev_consume_skb_any.

At 54 separate changes I will post each change as a separate patch (so
they can be reviewed) but for general sanity sake I have gathered them
all into a git branch for easy acces.

10 years agovxlan: fix nonfunctional neigh_reduce()
David Stevens [Mon, 24 Mar 2014 14:39:58 +0000 (10:39 -0400)]
vxlan: fix nonfunctional neigh_reduce()

The VXLAN neigh_reduce() code is completely non-functional since
check-in. Specific errors:

1) The original code drops all packets with a multicast destination address,
even though neighbor solicitations are sent to the solicited-node
address, a multicast address. The code after this check was never run.
2) The neighbor table lookup used the IPv6 header destination, which is the
solicited node address, rather than the target address from the
neighbor solicitation. So neighbor lookups would always fail if it
got this far. Also for L3MISSes.
3) The code calls ndisc_send_na(), which does a send on the tunnel device.
The context for neigh_reduce() is the transmit path, vxlan_xmit(),
where the host or a bridge-attached neighbor is trying to transmit
a neighbor solicitation. To respond to it, the tunnel endpoint needs
to do a *receive* of the appropriate neighbor advertisement. Doing a
send, would only try to send the advertisement, encapsulated, to the
remote destinations in the fdb -- hosts that definitely did not do the
corresponding solicitation.
4) The code uses the tunnel endpoint IPv6 forwarding flag to determine the
isrouter flag in the advertisement. This has nothing to do with whether
or not the target is a router, and generally won't be set since the
tunnel endpoint is bridging, not routing, traffic.

The patch below creates a proxy neighbor advertisement to respond to
neighbor solicitions as intended, providing proper IPv6 support for neighbor
reduction.

net: davinci_emac: Fix interrupt requests and error handling

since commit 6892b41d9701283085b655c6086fb57a5d63fa47 (Linux 3.11) the
davinci_emac driver is broken. After doing ifconfig down, ifconfig up,
requesting the interrupts for the driver fails. The interface remains dead

The first patch in this patchset reverts commit
6892b41d9701283085b655c6086fb57a5d63fa47 partially and makes the driver
useable again.

During the work on the first patch, a number of bugs in the error handling
of the driver's ndo_open code were found. The second patch fixes these bugs.

I believe the first patch meets the rules for stable kernels, I therefore added
the stable tag to this patch. The second patch is just cleanup, the code
that is fixed by this patch is only executed in case of an error.

Christian Riesch [Mon, 24 Mar 2014 12:46:27 +0000 (13:46 +0100)]
net: davinci_emac: Fix rollback of emac_dev_open()

If an error occurs during the initialization in emac_dev_open() (the
driver's ndo_open function), interrupts, DMA descriptors etc. must be freed.
The current rollback code is buggy in several ways.

  1) Freeing the interrupts. The current code will not free all interrupts
     that were requested by the driver. Furthermore,  the code tries to do a
     platform_get_resource(priv->pdev, IORESOURCE_IRQ, -1) in its last
     iteration.

     This patch fixes these bugs.

  2) Wrong order of err: and rollback: labels. If the setup of the PHY in
     the code fails, the interrupts that have been requested before are
     not freed:

        request irq
                if requesting irqs fails, goto rollback
        setup phy
                if phy setup fails, goto err
        return 0

     rollback:
        free irqs
     err:

     This patch brings the code into the correct order.

  3) The code calls napi_enable() and emac_int_enable(), but does not
     undo both in case of an error.

     This patch adds calls of emac_int_disable() and napi_disable() to the
     rollback code.

  4) RX DMA descriptors are not freed in case of an error: Right before
     requesting the irqs, the function creates DMA descriptors for the
     RX channel. These RX descriptors are never freed when we jump to either
     rollback or err.

     This patch adds code for freeing the DMA descriptors in the case of
     an initialization error. This required a modification of
     cpdma_ctrl_stop() in davinci_cpdma.c: We must be able to call this
     function to free the DMA descriptors while the DMA channels are
     in IDLE state (before cpdma_ctlr_start() was called).

Tested on a custom board with the Texas Instruments AM1808.

the call of request_irq is replaced by devm_request_irq and the call

emac_dev_open, doing ifconfig up/down on the board requests the

In arch_cpu_idle() we must enable %pil based interrupts before

As per the Hypervisor API documentation for cpu_yield:

Interrupts which are blocked by some mechanism other that
pstate.ie (for example %pil) are not guaranteed to cause
a return from this service.

It seems that only first generation Niagara chips are hit by this

and wake up anyways from %pil events, whereas in first generation
chips the yield is implemented completely in hypervisor code and
