After port reconfiguration (port split, media type change)
firmware will continue to report old configuration until
reboot. NSP will inform us that reconfiguration is pending.
To avoid user confusion refuse to spawn netdevs until the
new configuration is applied (reboot).
We need to split the netdev to eth_table port matching from
MAC search and move it earlier in the probe() flow.

pull-request: can-next 2017-03-03
this is a pull request of 5 patches for net-next/master.
There are two patches by Yegor Yefremov which convert the ti_hecc
driver into a DT only driver, as there is no in-tree user of the old
platform driver interface anymore. The next patch by Mario Kicherer
adds network namespace support to the can subsystem. The last two
patches by Akshay Bhat add support for the holt_hi311x SPI CAN driver.

rtnetlink: Updates to rtnetlink_event()
This series came out of the conversation that started as a result
my first attempt to add netdevice event info to netlink messages.
This series converts event processing to a 'white list', where
we explicitely permit events to generate netlink messages. This
is meant to make people take a closer look and determine wheter
these events should really trigger netlink messages.
I am also adding a V2 of my patch to add event type to the netlink
message. This version supports all events that we currently generate.
I will also update my patch to iproute that will show this data
through 'ip monitor'.
I actually need the ability to trap NETDEV_NOTIFY_PEERS event
(as well as possible NETDEV_RESEND_IGMP) to support hanlding of
macvtap on top of bonding. I hope others will also find this info usefull.
V2: Added missed events (from David Ahern)
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
When netdev events happen, a rtnetlink_event() handler will send
messages for every event in it's white list. These messages contain
current information about a particular device, but they do not include
the iformation about which event just happened. The consumer of
the message has to try to infer this information. In some cases
(ex: NETDEV_NOTIFY_PEERS), that is not possible.
This patch adds a new extension to RTM_NEWLINK message called IFLA_EVENT
that would have an encoding of the which event triggered this
message. This would allow the the message consumer to easily determine
if it is interested in a particular event or not.

The rtnetlink_event currently functions as a blacklist where
we block cerntain netdev events from being sent to user space.
As a result, events have been added to the system that userspace
probably doesn't care about.
This patch converts the implementation to the white list so that
newly events would have to be specifically added to the list to
be sent to userspace. This would force new event implementers to
consider whether a given event is usefull to user space or if it's
just a kernel event.

Since commit d6580a9f15 ("kexec: sysrq: simplify sysrq-c handler"),
the sysrq handler for the 'c' key has been sysrq_crash_op. Debugging
code in the ibm_emac driver also tries to register a handler for the 'c'
key, but this has no effect because register_sysrq_key() doesn't replace
existing handlers. Since evidently no one has cared enough to fix this
in the last 8 years, and it's very rare for drivers to register sysrq
handlers (for good reason), just remove the dead code.

Earlier patch c4adfc822b ("bonding: make speed, duplex setting
consistent with link state") made an attempt to keep slave state
consistent with speed and duplex settings. Unfortunately link-state
transition is used to change the active link especially when used
in conjunction with mii-mon. The above mentioned patch broke that
logic. Also when speed and duplex settings for a link are updated
during a link-event, the link-status should not be changed to
invoke correct transition logic.
This patch fixes this issue by moving the link-state update outside
of the bond_update_speed_duplex() fn and to the places where this fn
is called and update link-state selectively.

When resetting the device, we take a synchronous firmware-loading code
path, which borrows a lot from the asynchronous path used at probe time.
We don't catch errors correctly though, which means that in the PCIe
driver, we may try to dereference the 'adapter' struct after
mwifiex_fw_dpc() has freed it. See this (erronous) print in
mwifiex_pcie_reset_notify():
mwifiex_dbg(adapter, INFO, "%s, successful\n", __func__);
Let's instead refactor the synchronous (or "!req_fw_nowait") path so
that we propagate errors and handle them properly.
This fixes a use-after-free issue in the PCIe driver, as well as a
misleading debug message ("successful"). It looks like the SDIO driver
doesn't have these problems, since it doesn't do anything after
mwifiex_reinit_sw().

If we fail to reinit the FW when resetting the device (in the
synchronous version of mwifiex_init_hw_fw() -> mwifiex_fw_dpc()),
mwifiex_fw_dpc() will tear down the interface and free up the adapter.
But we don't actually check for all failure cases of mwifiex_fw_dpc(),
so some of them fall through and dereference adapter->fw_done with a
freed adapter, causing a use-after-free bug.
In any case, mwifiex_fw_dpc() will always signal FW completion -- in the
error OR success case -- so at best, this was repeat work. Let's not do
it.
