For a failing smc_listen_rdma_finish() smc_listen_decline() is
called. If fallback is possible, the new socket is already enqueued
to be accepted in smc_listen_decline(). Avoid enqueuing a second time
afterwards in this case, otherwise the smc_create_lgr_pending lock

In state SMC_INIT smc_poll() delegates polling to the internal
CLC socket. This means, once the connect worker has finished
its kernel_connect() step, the poll wake-up may occur. This is not
intended. The wake-up should occur from the wake up call in
smc_connect_work() after __smc_connect() has finished.
Thus in state SMC_INIT this patch now calls sock_poll_wait() on the
main SMC socket.

EtherAVB hardware requires 0 to be written to status register bits in
order to clear them, however, care must be taken not to:
1. Clear other bits, by writing zero to them
2. Write one to reserved bits
This patch corrects the ravb driver with respect to the second point above.
This is done by defining reserved bit masks for the affected registers and,
after auditing the code, ensure all sites that may write a one to a
reserved bit use are suitably masked.

On the Netgear WNDAP620, the emac ethernet isn't receiving nor
xmitting any frames from/to the RTL8363SB (identifies itself
as a RTL8367RB).
This is caused by the emac hardware not knowing the forced link
parameters for speed, duplex, pause, etc.
This begs the question, how this was working on the original
driver code, when it was necessary to set the phy_address and
phy_map to 0xffffffff. But I guess without access to the old
PPC405/440/460 hardware, it's not possible to know.

According to ETSI TS 102 622 specification chapter 4.4 pipe identifier
is 7 bits long which allows for 128 unique pipe IDs. Because
NFC_HCI_MAX_PIPES is used as the number of pipes supported and not
as the max pipe ID, its value should be 128 instead of 127.
nfc_hci_recv_from_llc extracts pipe ID from packet header using
NFC_HCI_FRAGMENT(0x7F) mask which allows for pipe ID value of 127.
Same happens when NCI_HCP_MSG_GET_PIPE() is being used. With
pipes array having only 127 elements and pipe ID of 127 the OOB memory
access will result.

When handling SHDLC I-Frame commands "pipe" field used for indexing
into an array should be checked before usage. If left unchecked it
might access memory outside of the array of size NFC_HCI_MAX_PIPES(127).
Malformed NFC HCI frames could be injected by a malicious NFC device
communicating with the device being attacked (remote attack vector),
or even by an attacker with physical access to the I2C bus such that
they could influence the data transfers on that bus (local attack vector).
skb->data is controlled by the attacker and has only been sanitized in
the most trivial ways (CRC check), therefore we can consider the
create_info struct and all of its members to tainted. 'create_info->pipe'
with max value of 255 (uint8) is used to take an offset of the
hdev->pipes array of 127 elements which can lead to OOB write.

Commonly, ethernet addresses are just using a policy of
{ .len = ETH_ALEN }
which leaves userspace free to send more data than it should,
which may hide bugs.
Introduce NLA_EXACT_LEN which checks for exact size, rejecting
the attribute if it's not exactly that length. Also add
NLA_EXACT_LEN_WARN which requires the minimum length and will
warn on longer attributes, for backward compatibility.
Use these to define NLA_POLICY_ETH_ADDR (new strict policy) and
NLA_POLICY_ETH_ADDR_COMPAT (compatible policy with warning);
these are used like this:
static const struct nla_policy <name>[...] = {
[NL_ATTR_NAME] = NLA_POLICY_ETH_ADDR,
...
};

In some situations some netlink attributes may be used for output
only (kernel->userspace) or may be reserved for future use. It's
then helpful to be able to prevent userspace from using them in
messages sent to the kernel, since they'd otherwise be ignored and
any future will become impossible if this happens.
Add NLA_REJECT to the policy which does nothing but reject (with
EINVAL) validation of any messages containing this attribute.
Allow for returning a specific extended ACK error message in the
validation_data pointer.
While at it clear up the documentation a bit - the NLA_BITFIELD32
documentation was added to the list of len field descriptions.
Also, use NL_SET_BAD_ATTR() in one place where it's open-coded.
The specific case I have in mind now is a shared nested attribute
containing request/response data, and it would be pointless and
potentially confusing to have userspace include response data in
the messages that actually contain a request.

Currently we are always setting the tail address of descriptor list to
the end of the pre-allocated list.
According to databook this is not correct. Tail address should point to
the last available descriptor + 1, which means we have to update the
tail address everytime we call the xmit function.
This should make no impact in older versions of MAC but in newer
versions there are some DMA features which allows the IP to fetch
descriptors in advance and in a non sequential order so its critical
that we set the tail address correctly.

====================
40GbE Intel Wired LAN Driver Updates 2018-09-18
This series contains changes to i40evf so that it becomes a more
generic virtual function driver for current and future silicon.
While doing the rename of i40evf to a more generic name of iavf,
we also put the driver on a severe diet due to how much of the
code was unneeded or was unused. The outcome is a lean and mean
virtual function driver that continues to work on existing 40GbE
(i40e) virtual devices and prepped for future supported devices,
like the 100GbE (ice) virtual devices.
This solves 2 issues we saw coming or were already present, the
first was constant code duplication happening with i40e/i40evf,
when much of the duplicate code in the i40evf was not used or was
not needed. The second was to remove the future confusion of why
future VF devices that were not considered "40GbE" only devices
were supported by i40evf.
The thought is that iavf will be the virtual function driver for
all future devices, so it should have a "generic" name to properly
represent that it is the VF driver for multiple generations of
devices.
The last patch in this series is unreleated to the iavf conversion
and just has to do with a MODULE_LICENSE correction.
Known Caveats:
Existing user space configurations may have to change, but the module
alias in patch 1 helps a bit here.

Remove a bunch of unused code and reformat a few lines. Also
remove some now un-necessary files.

The original PCI error recovery functionality was for the powerpc-specific
IBM EEH feature. PCIe subsequently added some similar features, including
AER and DPC, that can be used on any architecture.
We want the generic PCI core error handling support to work with all of
these features. Driver error recovery callbacks should be independent of
which feature the platform provides.
Add the generic PCI core error recovery files to the powerpc EEH
MAINTAINERS entry so the powerpc folks will be copied on changes to the
generic PCI error handling strategy.
Add Sam and Oliver as maintainers for this area.

In order to determine a sane default cache allocation for a new CAT/CDP
resource group, all resource groups are checked to determine which cache
portions are available to share. At this time all possible CLOSIDs
that can be supported by the resource is checked. This is problematic
if the resource supports more CLOSIDs than another CAT/CDP resource. In
this case, the number of CLOSIDs that could be allocated are fewer than
the number of CLOSIDs that can be supported by the resource.
Limit the check of closids to that what is supported by the system based
on the minimum across all resources.

It is possible for a resource group to consist out of MBA as well as
CAT/CDP resources. The "exclusive" resource mode only applies to the
CAT/CDP resources since MBA allocations cannot be specified to overlap
or not. When a user requests a resource group to become "exclusive" then it
can only be successful if there are CAT/CDP resources in the group
and none of their CBMs associated with the group's CLOSID overlaps with
any other resource group.
Fix the "exclusive" mode setting by failing if there isn't any CAT/CDP
resource in the group and ensuring that the CBM checking is only done on
CAT/CDP resources.
