61414f5ec9 FDDI: defza: Add support for DEC FDDIcontroller 700 TURBOchannel adapter
Add support for the DEC FDDIcontroller 700 (DEFZA), Digital Equipment
Corporation's first-generation FDDI network interface adapter, made for
TURBOchannel and based on a discrete version of what eventually became
Motorola's widely used CAMEL chipset.

The CAMEL chipset is present for example in the DEC FDDIcontroller
TURBOchannel, EISA and PCI adapters (DEFTA/DEFEA/DEFPA) that we support
with the `defxx' driver, however the host bus interface logic and the
firmware API are different in the DEFZA and hence a separate driver is
required.

There isn't much to say about the driver except that it works, but there
is one peculiarity to mention.  The adapter implements two Tx/Rx queue
pairs.

Of these one pair is the usual network Tx/Rx queue pair, in this case
used by the adapter to exchange frames with the ring, via the RMC (Ring
Memory Controller) chip.  The Tx queue is handled directly by the RMC
chip and resides in onboard packet memory.  The Rx queue is maintained
via DMA in host memory by adapter's firmware copying received data
stored by the RMC in onboard packet memory.

The other pair is used to communicate SMT frames with adapter's
firmware.  Any SMT frame received from the RMC via the Rx queue must be
queued back by the driver to the SMT Rx queue for the firmware to
process.  Similarly the firmware uses the SMT Tx queue to supply the
driver with SMT frames that must be queued back to the Tx queue for the
RMC to send to the ring.

This solution was chosen because the designers ran out of PCB space and
could not squeeze in more logic onto the board that would be required to
handle this SMT frame traffic without the need to involve the driver, as
with the later DEFTA/DEFEA/DEFPA adapters.

Finally the driver does some Frame Control byte decoding, so to avoid
magic numbers some macros are added to <linux/if_fddi.h>.

7c6bb7d2fa net/ipv6: Add knob to skip DELROUTE message on device down
Another difference between IPv4 and IPv6 is the generation of RTM_DELROUTE
notifications when a device is taken down (admin down) or deleted. IPv4
does not generate a message for routes evicted by the down or delete;
IPv6 does. A NOS at scale really needs to avoid these messages and have
IPv4 and IPv6 behave similarly, relying on userspace to handle link
notifications and evict the routes.

At this point existing user behavior needs to be preserved. Since
notifications are a global action (not per app) the only way to preserve
existing behavior and allow the messages to be skipped is to add a new
sysctl (net/ipv6/route/skip_notify_on_dev_down) which can be set to
disable the notificatioons.

IPv6 route code already supports the option to skip the message (it is
used for multipath routes for example). Besides the new sysctl we need
to pass the skip_notify setting through the generic fib6_clean and
fib6_walk functions to fib6_clean_node and to set skip_notify on calls
to __ip_del_rt for the addrconf_ifdown path.

Alexei Starovoitov says:

====================
pull-request: bpf-next 2018-10-08

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) sk_lookup_[tcp|udp] and sk_release helpers from Joe Stringer which allow
BPF programs to perform lookups for sockets in a network namespace. This would
allow programs to determine early on in processing whether the stack is
expecting to receive the packet, and perform some action (eg drop,
forward somewhere) based on this information.

2) per-cpu cgroup local storage from Roman Gushchin.
Per-cpu cgroup local storage is very similar to simple cgroup storage
except all the data is per-cpu. The main goal of per-cpu variant is to
implement super fast counters (e.g. packet counters), which don't require
neither lookups, neither atomic operations in a fast path.
The example of these hybrid counters is in selftests/bpf/netcnt_prog.c

3) allow HW offload of programs with BPF-to-BPF function calls from Quentin Monnet

4) support more than 64-byte key/value in HW offloaded BPF maps from Jakub Kicinski

5) rename of libbpf interfaces from Andrey Ignatov.
libbpf is maturing as a library and should follow good practices in
library design and implementation to play well with other libraries.
This patch set brings consistent naming convention to global symbols.

6) relicense libbpf as LGPL-2.1 OR BSD-2-Clause from Alexei Starovoitov
to let Apache2 projects use libbpf

7) various AF_XDP fixes from Björn and Magnus

e908bcf4f1 rxrpc: Allow the reply time to be obtained on a client call
Allow the epoch value to be queried on a server connection.  This is in the
rxrpc header of every packet for use in routing and is derived from the
client's state.  It's also not supposed to change unless the client gets
restarted.

AFS can make use of this information to deduce whether a fileserver has
been restarted because the fileserver makes client calls to the filesystem
driver's cache manager to send notifications (ie. callback breaks) about
conflicting changes from other clients.  These convey the fileserver's own
epoch value back to the filesystem.

a27fb6d983 This pull request is slightly bigger than usual at this stage, but
I swear I would have sent it the same to Linus!  The main cause for
 this is that I was on vacation until two weeks ago and it took a while
 to sort all the pending patches between 4.19 and 4.20, test them and
 so on.
 
 It's mostly small bugfixes and cleanups, mostly around x86 nested
 virtualization.  One important change, not related to nested
 virtualization, is that the ability for the guest kernel to trap CPUID
 instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is now
 masked by default.  This is because the feature is detected through an
 MSR; a very bad idea that Intel seems to like more and more.  Some
 applications choke if the other fields of that MSR are not initialized
 as on real hardware, hence we have to disable the whole MSR by default,
 as was the case before Linux 4.12.

6fbbde9a19 KVM: x86: Control guest reads of MSR_PLATFORM_INFO
Add KVM_CAP_MSR_PLATFORM_INFO so that userspace can disable guest access
to reads of MSR_PLATFORM_INFO.

Disabling access to reads of this MSR gives userspace the control to "expose"
this platform-dependent information to guests in a clear way. As it exists
today, guests that read this MSR would get unpopulated information if userspace
hadn't already set it (and prior to this patch series, only the CPUID faulting
information could have been populated). This existing interface could be
confusing if guests don't handle the potential for incorrect/incomplete
information gracefully (e.g. zero reported for base frequency).

Jeff Kirsher says:

====================
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.

8062b2263a intel-ethernet: rename i40evf to iavf
Rename the Intel Ethernet Adaptive Virtual Function driver
(i40evf) to a new name (iavf) that is more consistent with
the ongoing maintenance of the driver as the universal VF driver
for multiple product lines.

This first patch fixes up the directory names and the .ko name,
intentionally ignoring the function names inside the driver
for now.  Basically this is the simplest patch that gets
the rename done and will be followed by other patches that
rename the internal functions.

This patch also addresses a couple of string/name issues
and updates the Copyright year.

Also, made sure to add a MODULE_ALIAS to the old name.
