2f87208efb drivers: net: davinci_cpdma: double free on error
We recently change the kzalloc() to devm_kzalloc() so freeing "ctlr"
here could lead to a double free.

68bc74feb0 net: davinci_emac: fix oops caused by uninitialized ndev->dev
Commit e194312854 (drivers: net:
davinci_cpdma: Convert kzalloc() to devm_kzalloc()) triggered
a bug in emac_probe() wherein dev member of net_device is used
for devres allocations even before it is initialized.

This patch fixes that by using the struct device in platform_device
instead.

While at it, use &pdev->dev consistently for console messages instead
of using ndev->dev for just one case and remove an unnecessary line
continuation.

Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.

Mostly done via coccinelle script:

59993f48b3 Revert "net: eth: cpsw: Correctly attach to GPIO bitbang MDIO driver"
This reverts commit f8d56d8f89 ("net:
 eth: cpsw: Correctly attach to GPIO bitbang MDIO driver").

Fix potential null-pointer dereference at probe if the mdio-gpio device
has not been successfully probed yet.

The offending commit is plain wrong for a number of reasons. First of
all it accesses internal driver data of an unrelated device. Neither
does it check that the data is non-null (which it is in case the device
has not been probed yet).

Furthermore, the decision on whether to treat any driver data according
to the mdio-gpio driver's internals is made based on the node name. But
the name is not compared against "mdio" which is the normal name for the
node, but rather against "gpio" which the node does not have to be named
(and shouldn't be according to the binding documentation). [ If this
hack is to be kept out-of-tree it should at least be matching against
the compatible property. ]

f63a975e8f drivers: net: cpsw: enable interrupts after napi enable and clearing previous interrupts
When the Ethernet interface is put down and up with heavy Ethernet
traffic, then there is prossibility of an interrupt waiting in irq
controller to be processed, so when the interface is brought up again
just after enable interrupt, it goes to ISR due to the previous
unhandled interrutp and in ISR napi is not scheduled as the napi
is not enabled in ndo_open which results in disabled interrupt for
CPSW and no packets are received in cpsw. So this patch moves enabling
of interupts after napi_enable and clearing CPDMA interrupts.

16e5c57da6 drivers: net: cpsw: discard all packets received when interface is down
When the Ethernet interface is brought down during high Ethernet traffic,
then cpsw creates the following warn dump. When cpdma has already processed
the packet then the status will be greater than 0, so the cpsw_rx_handler
considers that the interface is up and try to resubmit one more rx buffer
to cpdma which fails as the DMA is in teardown process. This can be avoided
by checking the interface state and then process the received packet, if the
interface is down just discard and free the skb and return.

164d8c6665 net: ptp: do not reimplement PTP/BPF classifier
There are currently pch_gbe, cpts, and ixp4xx_eth drivers that open-code
and reimplement a BPF classifier for the PTP protocol. Since all of them
effectively do the very same thing and load the very same PTP/BPF filter,
we can just consolidate that code by introducing ptp_classify_raw() in
the time-stamping core framework which can be used in drivers.

As drivers get initialized after bootstrapping the core networking
subsystem, they can make use of ptp_insns wrapped through
ptp_classify_raw(), which allows to simplify and remove PTP classifier
setup code in drivers.

Joint work with Alexei Starovoitov.

cd11cf5053 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.

33b7107f59 net: davinci_emac: Replace devm_request_irq with request_irq
In commit 6892b41d97

net: davinci: emac: Convert to devm_* api

the call of request_irq is replaced by devm_request_irq and the call
of free_irq is removed. But since interrupts are requested in
emac_dev_open, doing ifconfig up/down on the board requests the
interrupts again each time, causing devm_request_irq to fail. The
interface is dead until the device is rebooted.

This patch reverts said commit partially: It changes the driver back
to use request_irq instead of devm_request_irq, puts free_irq back in
place, but keeps the remaining changes of the original patch.

moved cpts_register()/cpts_unregister() to  ndo_open()/ndo_stop(), but failed
to remove cpts_register in cpsw_probe() which leads to a double registration
and the following debug object splat.

8dc43ddc9f net: eth: cpsw: Use net_device_stats from struct net_device
Instead of using an own copy of struct net_device_stats in struct
cpsw_priv, use stats from struct net_device. Also remove the thus
unnecessary .ndo_get_stats function, as it just returns dev->stats,
which is the default.

The SIT driver conflict consists of a bug fix being done by hand
in 'net' (missing u64_stats_init()) whilst in 'net-next' a helper
was created (netdev_alloc_pcpu_stats()) which takes care of this.

The two wireless conflicts were overlapping changes.

3995d265b3 net: cpsw: fix cpdma rx descriptor leak on down interface
This patch fixes a CPDMA RX Descriptor leak that occurs after taking
the interface down when the CPSW is in Dual MAC mode. Previously
the CPSW_ALE port was left open up which causes packets to be received
and processed by the RX interrupt handler and were passed to the
non active network interface where they were ignored.

The fix is for the slave_stop function of the selected interface
to disable the respective CPSW_ALE Port from forwarding packets. This
blocks traffic from being received on the inactive interface.

0d961b3b52 drivers: net: cpsw: fix buggy loop condition
Commit 0cd8f9cc06 ("drivers: net: cpsw:
enable promiscuous mode support")

Enable promiscuous mode support for CPSW.

Introduced a crash on an am335x based board (similiar to am335x-evm).
Reason is buggy end condition in for loop in cpsw_set_promiscious()

for (i = 0; i <= priv->data.slaves; i++)

should be

for (i = 0; i < priv->data.slaves; i++)

Fix this ...

89e101729b net: cpsw: catch of_get_phy_mode failing and propagate error
It's wrong if the device tree doesn't provide a phy-mode property for
the cpsw slaves as it is documented to be required in
Documentation/devicetree/bindings/net/cpsw.txt.

Anyhow it's nice to catch that problem, still more as it used to work
without this property up to commit 388367a5a9 (drivers: net: cpsw: use
cpsw-phy-sel driver to configure phy mode) which is in v3.13-rc1.

When the GPIO bitbang MDIO driver is used instead of the Davinci MDIO driver
we need to configure the phy_id string differently. Otherwise this string

db850559a3 drivers: net : cpsw: pass proper device name while requesting irq
During checking the interrupts with "cat /proc/interrupts", it is showing
device name as (null), this change was done with commit id aa1a15e2d where
request_irq is changed to devm_request_irq also changing the irq name from
platform device name to net device name, but the net device is not
registered at this point with the network frame work, so devm_request_irq
is called with device name as NULL, by which it is showed as "(null)" in
"cat /proc/interrupts". So this patch changes back irq name to platform
device name itself in devm_request_irq so that the device name shows as
below.
