git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
- Improve the efficiency and performance of reading nvdimm-namespace
labels. Reduce the amount of label data read at driver load time by a
few orders of magnitude. Reduce heavyweight call-outs to
platform-firmware routines.
- Handle media errors located in the 'struct page' array stored on a
persistent memory namespace. Let the kernel clear these errors rather
than an awkward userspace workaround.
- Fix Address Range Scrub (ARS) completion tracking. Correct occasions
where the kernel indicates completion of ARS before submission.
- Fix asynchronous device registration reference counting.
- Add support for reporting an nvdimm dirty-shutdown-count via sysfs.
- Fix various small libnvdimm core and uapi issues.

With 4.19, programs like ebtables fail to build when they include

MOVDIR64B moves 64-bytes as direct-store with 64-bytes write atomicity.
Direct store is implemented by using write combining (WC) for writing
data directly into memory without caching the data.
In low latency offload (e.g. Non-Volatile Memory, etc), MOVDIR64B writes
work descriptors (and data in some cases) to device-hosted work-queues
atomically without cache pollution.
Availability of the MOVDIR64B instruction is indicated by the
presence of the CPUID feature flag MOVDIR64B (CPUID.0x07.0x0:ECX[bit 28]).
Please check the latest Intel Architecture Instruction Set Extensions
and Future Features Programming Reference for more details on the CPUID
feature MOVDIR64B flag.

MOVDIRI moves doubleword or quadword from register to memory through
direct store which is implemented by using write combining (WC) for
writing data directly into memory without caching the data.
Programmable agents can handle streaming offload (e.g. high speed packet
processing in network). Hardware implements a doorbell (tail pointer)
register that is updated by software when adding new work-elements to
the streaming offload work-queue.
MOVDIRI can be used as the doorbell write which is a 4-byte or 8-byte
uncachable write to MMIO. MOVDIRI has lower overhead than other ways
to write the doorbell.
Availability of the MOVDIRI instruction is indicated by the presence of
the CPUID feature flag MOVDIRI(CPUID.0x07.0x0:ECX[bit 27]).
Please check the latest Intel Architecture Instruction Set Extensions
and Future Features Programming Reference for more details on the CPUID
feature MOVDIRI flag.

The vhost-scsi driver currently does not handle any control queue
operations. In particular, vhost_scsi_ctl_handle_kick, merely prints out
a debug message but does nothing else. This can cause guest VMs to hang.
As part of SCSI recovery from an error, e.g., an I/O timeout, the SCSI
midlayer attempts to abort the failed operation. The SCSI virtio driver
translates the abort to a SCSI TMF request that gets put on the control
queue (virtscsi_abort -> virtscsi_tmf). The SCSI virtio driver then
waits indefinitely for this request to be completed, but it never will
because vhost-scsi never responds to that request.
To avoid a hang, always respond to control queue operations; explicitly
reject TMF requests, and return a no-op response to event requests.

[Why]
Carrizo and Stoney have severe corruption when trying to power
4k 60 monitors over HDMI connectors that support 4k 60.
Carrizo and Stoney require retimers and redrivers to support 4k 60
over HDMI. This driver does not currently support these. Thus, 4k 60
HDMI (and all other modes requiring over 300MHz) should be disabled.
[How]
Reduce the dce11 HDMI pixel clock cap to 300000kHz.

Negotiation of the VIRTIO_BALLOON_F_FREE_PAGE_HINT feature indicates the
support of reporting hints of guest free pages to host via virtio-balloon.
Currenlty, only free page blocks of MAX_ORDER - 1 are reported. They are
obtained one by one from the mm free list via the regular allocation
function.
Host requests the guest to report free page hints by sending a new cmd id
to the guest via the free_page_report_cmd_id configuration register. When
the guest starts to report, it first sends a start cmd to host via the
free page vq, which acks to host the cmd id received. When the guest
finishes reporting free pages, a stop cmd is sent to host via the vq.
Host may also send a stop cmd id to the guest to stop the reporting.
VIRTIO_BALLOON_CMD_ID_STOP: Host sends this cmd to stop the guest
reporting.
VIRTIO_BALLOON_CMD_ID_DONE: Host sends this cmd to tell the guest that
the reported pages are ready to be freed.
Why does the guest free the reported pages when host tells it is ready to
free?
This is because freeing pages appears to be expensive for live migration.
free_pages() dirties memory very quickly and makes the live migraion not
converge in some cases. So it is good to delay the free_page operation
when the migration is done, and host sends a command to guest about that.
Why do we need the new VIRTIO_BALLOON_CMD_ID_DONE, instead of reusing
VIRTIO_BALLOON_CMD_ID_STOP?
This is because live migration is usually done in several rounds. At the
end of each round, host needs to send a VIRTIO_BALLOON_CMD_ID_STOP cmd to
the guest to stop (or say pause) the reporting. The guest resumes the
reporting when it receives a new command id at the beginning of the next
round. So we need a new cmd id to distinguish between "stop reporting" and
"ready to free the reported pages".
TODO:
- Add a batch page allocation API to amortize the allocation overhead.

Intel Wired LAN Driver Fixes 2018-10-24
This series contains fixes for the ice driver.
Anirudh fixes a namespace issue which was introduced with a previous
patch to remove ice_netpoll. Fixed up the device ID define names to
align with the branding string names. Use the capability count returned
by the firmware, instead of calculating the count. Introduced driver
workarounds due to current firmware limitations. Fixed the queue
mapping for a VF, which needs to be set in the config and scatter queue
modes. Fixed the driver which is setup to handle link status events
(LSE), even though the firmware does not have this feature yet, so add
the ability to poll for link status changes while we wait for updated
firmware.

route
The intent of ip6_route_check_nh_onlink is to make sure the gateway
given for an onlink route is not actually on a connected route for
a different interface (e.g., 2001:db8:1::/64 is on dev eth1 and then
an onlink route has a via 2001:db8:1::1 dev eth2). If the gateway
lookup hits the default route then it most likely will be a different
interface than the onlink route which is ok.
Update ip6_route_check_nh_onlink to disregard the device mismatch
if the gateway lookup hits the default route. Turns out the existing
onlink tests are passing because there is no default route or it is
an unreachable default, so update the onlink tests to have a default
route other than unreachable.

When the physical link goes up or down, the driver is supposed to
receive a link status event (LSE). The driver currently has the code
to handle LSEs but there is no firmware support for this feature yet.
So this patch adds the ability for the driver to poll for link status
changes. The polling itself is done in ice_watchdog_subtask.
For namespace cleanliness, this patch also removes code that handles
LSE. This code will be reintroduced once the feature is officially
supported.

ice_dev_onetime_setup contains a couple of driver workarounds for current
firmware limitations. These workarounds are expected to go away once
these limitations are fixed in the firmware.
On a firmware release that has these issues addressed, these workarounds
(while unnecessary) will not break anything.

This is a copy and paste bug where we copied the sizeof() from the chunk
before. We're copying more data than intended but the destination is a
union so it doesn't cause memory corruption.

Current handling of CHECKSUM_COMPLETE packets by the UDP stack is
incorrect for any packet that has an incorrect checksum value.
udp4/6_csum_init() will both make a call to
__skb_checksum_validate_complete() to initialize/validate the csum
field when receiving a CHECKSUM_COMPLETE packet. When this packet
fails validation, skb->csum will be overwritten with the pseudoheader
checksum so the packet can be fully validated by software, but the
skb->ip_summed value will be left as CHECKSUM_COMPLETE so that way
the stack can later warn the user about their hardware spewing bad
checksums. Unfortunately, leaving the SKB in this state can cause
problems later on in the checksum calculation.
Since the the packet is still marked as CHECKSUM_COMPLETE,
udp_csum_pull_header() will SUBTRACT the checksum of the UDP header
from skb->csum instead of adding it, leaving us with a garbage value
in that field. Once we try to copy the packet to userspace in the
udp4/6_recvmsg(), we'll make a call to skb_copy_and_csum_datagram_msg()
to checksum the packet data and add it in the garbage skb->csum value
to perform our final validation check.
Since the value we're validating is not the proper checksum, it's possible
that the folded value could come out to 0, causing us not to drop the
packet. Instead, we believe that the packet was checksummed incorrectly
by hardware since skb->ip_summed is still CHECKSUM_COMPLETE, and we attempt
to warn the user with netdev_rx_csum_fault(skb->dev);
Unfortunately, since this is the UDP path, skb->dev has been overwritten
by skb->dev_scratch and is no longer a valid pointer, so we end up
reading invalid memory.
This patch addresses this problem in two ways:
1) Do not use the dev pointer when calling netdev_rx_csum_fault()
from skb_copy_and_csum_datagram_msg(). Since this gets called
from the UDP path where skb->dev has been overwritten, we have
no way of knowing if the pointer is still valid. Also for the
sake of consistency with the other uses of
netdev_rx_csum_fault(), don't attempt to call it if the
packet was checksummed by software.
2) Add better CHECKSUM_COMPLETE handling to udp4/6_csum_init().
If we receive a packet that's CHECKSUM_COMPLETE that fails
verification (i.e. skb->csum_valid == 0), check who performed
the calculation. It's possible that the checksum was done in
software by the network stack earlier (such as Netfilter's
CONNTRACK module), and if that says the checksum is bad,
we can drop the packet immediately instead of waiting until
we try and copy it to userspace. Otherwise, we need to
mark the SKB as CHECKSUM_NONE, since the skb->csum field
no longer contains the full packet checksum after the
call to __skb_checksum_validate_complete().

David Ahern says:
====================
net: Fixups for recent dump filtering changes
Li RongQing noted that tgt_net is leaked in ipv4 due to the recent change
to handle address dumps for a specific device. The report also applies to
ipv6 and other error paths. Patches 1 and 2 fix those leaks.
Patch 3 stops route dumps from erroring out when dumping across address
families and a table id is given. This is needed in preparation for
patch 4.
Patch 4 updates the rtnl_dump_all to handle a failure in one of the dumpit
functions. At the moment, if an address dump returns an error the dump all
loop breaks but the error is dropped. The result can be no data is returned
and no error either leaving the user wondering about the addresses.
Patches were tested with a modified iproute2 to add invalid data to the
dump request causing each specific failure path to be hit in addition
to positive testing that it works as it should when given valid data.

If an address, route or netconf dump request is sent for AF_UNSPEC, then
rtnl_dump_all is used to do the dump across all address families. If one
of the dumpit functions fails (e.g., invalid attributes in the dump
request) then rtnl_dump_all needs to propagate that error so the user
gets an appropriate response instead of just getting no data.

When doing a route dump across all address families, do not error out
if the table does not exist. This allows a route dump for AF_UNSPEC
with a table id that may only exist for some of the families.
Do return the table does not exist error if dumping routes for a
specific family and the table does not exist.

If test is being directly executed (with stdout opened on the
terminal) and the terminal capabilities indicate enough
colors, then use the existing scheme of green, red, and blue
to show when tests pass, fail or end in a different way.
When running the tests redirecting the stdout, for instance,
to a file, then colors are not shown, thus producing a more
readable output.

Now that ftracetest has over 80 tests, it is difficult to simply scroll
up the console window to find the failed tests when it reports just two
tests have failed. In order to make this stand out better, have the
color of the word "PASS" be green, "FAIL" and "XFAIL" be red, and all
other results be blue. This helps tremendously in quickly spotting the
failed tests by just scrolling up the console window.
