KVM updates for v4.20
ARM:
- Improved guest IPA space support (32 to 52 bits)
- RAS event delivery for 32bit
- PMU fixes
- Guest entry hardening
- Various cleanups
- Port of dirty_log_test selftest
PPC:
- Nested HV KVM support for radix guests on POWER9. The performance is
much better than with PR KVM. Migration and arbitrary level of
nesting is supported.
- Disable nested HV-KVM on early POWER9 chips that need a particular hardware
bug workaround
- One VM per core mode to prevent potential data leaks
- PCI pass-through optimization
- merge ppc-kvm topic branch and kvm-ppc-fixes to get a better base
s390:
- Initial version of AP crypto virtualization via vfio-mdev
- Improvement for vfio-ap
- Set the host program identifier
- Optimize page table locking
x86:
- Enable nested virtualization by default
- Implement Hyper-V IPI hypercalls
- Improve #PF and #DB handling
- Allow guests to use Enlightened VMCS
- Add migration selftests for VMCS and Enlightened VMCS
- Allow coalesced PIO accesses
- Add an option to perform nested VMCS host state consistency check
through hardware
- Automatic tuning of lapic_timer_advance_ns
- Many fixes, minor improvements, and cleanups

libnvdimm for 4.20
* 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. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJb0NuwAAoJEB7SkWpmfYgCjUYP/1RK35zXBJSArGE3CUkap/zp exuqUzhisiE3RER13hNvC59AxXB9QuIbzuR5bzWm+Lawuuaozn3iL2oKn3Gy0inl yE3m/1Hx43FTkYdH86K9bpaXtRfymppJiR475jRFin17xWL3UP2JJgYtGwoRfO4p OL1aLcGo04Y1E2h6sVx97DjiwWN5uTaG9jCciZr2w+s5pg1seuEOJcAayp+6D0Tq i2hZvQ6nyxxF2WzGqRk3ABbRySpQ5o4b33I/jjOKEFwYoB8UiZQeLuL2WRr1ztfz jo+aalLJjZTOMgeWPIYSuV+U8vySVUwXpMhfrMGnIRm5BuE9JUlHrYkMLcLZJyei 2qgQ65mDmoViBVx0w5k2nUjP8Ju5lC7fZTaLU60vf+3FZvBbSTtmog2+P0xMLg17 AHebl9slzJPO4r/z4XY+n9Bk/qOz6sfWk07LugfNcMdeZriJKr7BUclZVZDYiPJA /Rtnd8XRu8hS5Kfj7wK2QD5sVklS5VQhho/zzBZHQcQkQBfRo6f6YQ83N/6yoTKD p6nel3uRMX2n8+EPyODYt9j0cF7JupWqlSpRKUORrdSz85gt4D6W578tkJCEOCm0 JOm5HdLlwIhlIcam/w0blLOr+a0sISS4cWR72Vc/lSZHoM8ouQiQC/lplpiAAWwI 7pSmlYEEbZRQCy6ZrlVy =0FtE -----END PGP SIGNATURE----- Merge tag 'libnvdimm-for-4.20' of 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.

Merge tag 'xfs-4.20-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pul xfs updates from Dave Chinner:
"There's not a huge amount of change in this cycle - Darrick has been
out of action for a couple of months (hence me sending the last few
pull requests), so we decided a quiet cycle mainly focussed on bug
fixes was a good idea. Darrick will take the helm again at the end of
this merge window.
FYI, I may be sending another update later in the cycle - there's a
pending rework of the clone/dedupe_file_range code that fixes numerous
bugs that is spread amongst the VFS, XFS and ocfs2 code. It has been
reviewed and tested, Al and I just need to work out the details of the
merge, so it may come from him rather than me.
Summary:
- only support filesystems with unwritten extents
- add definition for statfs XFS magic number
- remove unused parameters around reflink code
- more debug for dangling delalloc extents
- cancel COW extents on extent swap targets
- fix quota stats output and clean up the code
- refactor some of the attribute code in preparation for parent
pointers
- fix several buffer handling bugs"

This is the bulk of GPIO changes for the v4.20 series:
Core changes:
- A patch series from Hans Verkuil to make it possible to
enable/disable IRQs on a GPIO line at runtime and drive GPIO
lines as output without having to put/get them from scratch.
The irqchip callbacks have been improved so that they can
use only the fastpatch callbacks to enable/disable irqs
like any normal irqchip, especially the gpiod_lock_as_irq()
has been improved to be callable in fastpath context.
A bunch of rework had to be done to achieve this but it is
a big win since I never liked to restrict this to slowpath.
The only call requireing slowpath was try_module_get() and
this is kept at the .request_resources() slowpath callback.
In the GPIO CEC driver this is a big win sine a single
line is used for both outgoing and incoming traffic, and
this needs to use IRQs for incoming traffic while actively
driving the line for outgoing traffic.
- Janusz Krzysztofik improved the GPIO array API to pass a
"cookie" (struct gpio_array) and a bitmap for setting or
getting multiple GPIO lines at once. This improvement
orginated in a specific need to speed up an OMAP1 driver and
has led to a much better API and real performance gains
when the state of the array can be used to bypass a lot
of checks and code when we want things to go really fast.
The previous code would minimize the number of calls
down to the driver callbacks assuming the CPU speed was
orders of magnitude faster than the I/O latency, but this
assumption was wrong on several platforms: what we needed
to do was to profile and improve the speed on the hot
path of the array functions and this change is now
completed.
- Clean out the painful and hard to grasp BNF experiments
from the device tree bindings. Future approaches are looking
into using JSON schema for this purpose. (Rob Herring
is floating a patch series.)
New drivers:
- The RCAR driver now supports r8a774a1 (RZ/G2M).
- Synopsys GPIO via CREGs driver.
Major improvements:
- Modernization of the EP93xx driver to use irqdomain and
other contemporary concepts.
- The ingenic driver has been merged into the Ingenic pin
control driver and removed from the GPIO subsystem.
- Debounce support in the ftgpio010 driver.

bpf: sk_msg program helper bpf_msg_push_data
This allows user to push data into a msg using sk_msg program types. The format is as follows, bpf_msg_push_data(msg, offset, len, flags) this will insert 'len' bytes at offset 'offset'. For example to prepend 10 bytes at the front of the message the user can, bpf_msg_push_data(msg, 0, 10, 0); This will invalidate data bounds so BPF user will have to then recheck data bounds after calling this. After this the msg size will have been updated and the user is free to write into the added bytes. We allow any offset/len as long as it is within the (data, data_end) range. However, a copy will be required if the ring is full and its possible for the helper to fail with ENOMEM or EINVAL errors which need to be handled by the BPF program. This can be used similar to XDP metadata to pass data between sk_msg layer and lower layers.

There is not a direct relationship between those functions and the current maps syscalls, hence a new MAP_LOOKUP_AND_DELETE_ELEM syscall is added, this is mapped to the pop operation in the queue/stack maps and it is still to implement in other kind of maps.

bpf: add queue and stack maps
Queue/stack maps implement a FIFO/LIFO data storage for ebpf programs. These maps support peek, pop and push operations that are exposed to eBPF programs through the new bpf_map[peek/pop/push] helpers. Those operations are exposed to userspace applications through the already existing syscalls in the following way: BPF_MAP_LOOKUP_ELEM -> peek BPF_MAP_LOOKUP_AND_DELETE_ELEM -> pop BPF_MAP_UPDATE_ELEM -> push Queue/stack maps are implemented using a buffer, tail and head indexes, hence BPF_F_NO_PREALLOC is not supported. As opposite to other maps, queue and stack do not use RCU for protecting maps values, the bpf_map[peek/pop] have a ARG_PTR_TO_UNINIT_MAP_VALUE argument that is a pointer to a memory zone where to save the value of a map. Basically the same as ARG_PTR_TO_UNINIT_MEM, but the size has not be passed as an extra argument. Our main motivation for implementing queue/stack maps was to keep track of a pool of elements, like network ports in a SNAT, however we forsee other use cases, like for exampling saving last N kernel events in a map and then analysing from userspace.

Furthermore, the actual machine page size could theoretically change from

UAPI: ndctl: Fix g++-unsupported initialisation in headers
The following code in the linux/ndctl header file:
static inline const char *nvdimm_bus_cmd_name(unsigned cmd)
{
static const char * const names[] = {
[ND_CMD_ARS_CAP] = "ars_cap",
[ND_CMD_ARS_START] = "ars_start",
[ND_CMD_ARS_STATUS] = "ars_status",
[ND_CMD_CLEAR_ERROR] = "clear_error",
[ND_CMD_CALL] = "cmd_call",
};
if (cmd < ARRAY_SIZE(names) && names[cmd])
return names[cmd];
return "unknown";
}
is broken in a number of ways:
(1) ARRAY_SIZE() is not generally defined.
(2) g++ does not support "non-trivial" array initialisers fully yet.
(3) Every file that calls this function will acquire a copy of names[].
The same goes for nvdimm_cmd_name().
Fix all three by converting to a switch statement where each case returns a
string. That way if cmd is a constant, the compiler can trivially reduce it
and, if not, the compiler can use a shared lookup table if it thinks that is
more efficient.
A better way would be to remove these functions and their arrays from the
header entirely.

kvm: x86: Introduce KVM_CAP_EXCEPTION_PAYLOAD
This is a per-VM capability which can be enabled by userspace so that the faulting linear address will be included with the information about a pending #PF in L2, and the "new DR6 bits" will be included with the information about a pending #DB in L2. With this capability enabled, the L1 hypervisor can now intercept #PF before CR2 is modified. Under VMX, the L1 hypervisor can now intercept #DB before DR6 and DR7 are modified. When userspace has enabled KVM_CAP_EXCEPTION_PAYLOAD, it should generally provide an appropriate payload when injecting a #PF or #DB exception via KVM_SET_VCPU_EVENTS. However, to support restoring old checkpoints, this payload is not required. Note that bit 16 of the "new DR6 bits" is set to indicate that a debug exception (#DB) or a breakpoint exception (#BP) occurred inside an RTM region while advanced debugging of RTM transactional regions was enabled. This is the reverse of DR6.RTM, which is cleared in this scenario. This capability also enables exception.pending in struct kvm_vcpu_events, which allows userspace to distinguish between pending and injected exceptions.

kvm/x86 : add coalesced pio support
Coalesced pio is based on coalesced mmio and can be used for some port like rtc port, pci-host config port and so on. Specially in case of rtc as coalesced pio, some versions of windows guest access rtc frequently because of rtc as system tick. guest access rtc like this: write register index to 0x70, then write or read data from 0x71. writing 0x70 port is just as index and do nothing else. So we can use coalesced pio to handle this scene to reduce VM-EXIT time. When starting and closing a virtual machine, it will access pci-host config port frequently. So setting these port as coalesced pio can reduce startup and shutdown time. without my patch, get the vm-exit time of accessing rtc 0x70 and piix 0xcf8 using perf tools: (guest OS : windows 7 64bit) IO Port Access Samples Samples% Time% Min Time Max Time Avg time 0x70:POUT 86 30.99% 74.59% 9us 29us 10.75us (+- 3.41%) 0xcf8:POUT 1119 2.60% 2.12% 2.79us 56.83us 3.41us (+- 2.23%) with my patch IO Port Access Samples Samples% Time% Min Time Max Time Avg time 0x70:POUT 106 32.02% 29.47% 0us 10us 1.57us (+- 7.38%) 0xcf8:POUT 1065 1.67% 0.28% 0.41us 65.44us 0.66us (+- 10.55%) Signed-off-by: Peng Hao <peng.hao2@zte.com.cn> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

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>. Signed-off-by: Maciej W.

net: bridge: add support for per-port vlan stats
This patch adds an option to have per-port vlan stats instead of the default global stats. The option can be set only when there are no port vlans in the bridge since we need to allocate the stats if it is set when vlans are being added to ports (and respectively free them when being deleted). Also bump RTNL_MAX_TYPE as the bridge is the largest user of options. The current stats design allows us to add these without any changes to the fast-path, it all comes down to the per-vlan stats pointer which, if this option is enabled, will be allocated for each port vlan instead of using the global bridge-wide one.

nl80211: Add per peer statistics to compute FCS error rate
Add support for drivers to report the total number of MPDUs received and the number of MPDUs received with an FCS error from a specific peer. These counters will be incremented only when the TA of the frame matches the MAC address of the peer irrespective of FCS error. It should be noted that the TA field in the frame might be corrupted when there is an FCS error and TA matching logic would fail in such cases. Hence, FCS error counter might not be fully accurate, but it can provide help in detecting bad RX links in significant number of cases. This FCS error counter without full accuracy can be used, e.g., to trigger a kick-out of a connected client with a bad link in AP mode to force such a client to roam to another AP.

====================
rxrpc: Fix packet reception code
Here are a set of patches that prepares for and fix problems in rxrpc's
package reception code. There serious problems are:
(A) There's a window between binding the socket and setting the data_ready
hook in which packets can find their way into the UDP socket's receive
queues.
(B) The skb_recv_udp() will return an error (and clear the error state) if
there was an error on the Tx side. rxrpc doesn't handle this.
(C) The rxrpc data_ready handler doesn't fully drain the UDP receive
queue.
(D) The rxrpc data_ready handler assumes it is called in a non-reentrant
state.
The second patch fixes (A) - (C); the third patch renders (B) and (C)
non-issues by using the recap_rcv hook instead of data_ready - and the
final patch fixes (D). That last is the most complex.
The preparatory patches are:
(1) Fix some places that are doing things in the wrong net namespace.
(2) Stop taking the rcu read lock as it's held by the IP input routine in
the call chain.
(3) Only end the Tx phase if *we* rotated the final packet out of the Tx
buffer.
(4) Don't assume that the call state won't change after dropping the
call_state lock.
(5) Only take receive window and MTU suze parameters from an ACK packet if
it's the latest ACK packet.
(6) Record connection-level abort information correctly.
(7) Fix a trace line.
And then there are three main patches - note that these are mixed in with
the preparatory patches somewhat:
(1) Fix the setup window (A), skb_recv_udp() error check (B) and packet
drainage (C).
(2) Switch to using the encap_rcv instead of data_ready to cut out the
effects of the UDP read queues and get the packets delivered directly.
(3) Add more locking into the various packet input paths to defend against
re-entrance (D).

Per-cpu cgroup local storage is very similar to simple cgroup storage except all the data is per-cpu.

netlink: Add new socket option to enable strict checking on dumps
Add a new socket option, NETLINK_DUMP_STRICT_CHK, that userspace can use via setsockopt to request strict checking of headers and attributes on dump requests. To get dump features such as kernel side filtering based on data in the header or attributes appended to the dump request, userspace must call setsockopt() for NETLINK_DUMP_STRICT_CHK and a non-zero value. Since the netlink sock and its flags are private to the af_netlink code, the strict checking flag is passed to dump handlers via a flag in the netlink_callback struct. For old userspace on new kernel there is no impact as all of the data checks in later patches are wrapped in a check on the new strict flag. For new userspace on old kernel, the setsockopt will fail and even if new userspace sets data in the headers and appended attributes the kernel will silently ignore it. Moving forward when the setsockopt succeeds, the new userspace on old kernel means the dump request can pass an attribute the kernel does not understand. The dump will then fail as the older kernel does not understand it. New userspace on new kernel setting the socket option gets the benefit of the improved data dump. Kernel side the NETLINK_DUMP_STRICT_CHK uapi is converted to a generic NETLINK_F_STRICT_CHK flag which can potentially be leveraged for tighter checking on the NEW, DEL, and SET commands.

rxrpc: Use the UDP encap_rcv hook
Use the UDP encap_rcv hook to cut the bit out of the rxrpc packet reception in which a packet is placed onto the UDP receive queue and then immediately removed again by rxrpc. Going via the queue in this manner seems like it should be unnecessary. This does, however, require the invention of a value to place in encap_type as that's one of the conditions to switch packets out to the encap_rcv hook. Possibly the value doesn't actually matter for anything other than sockopts on the UDP socket, which aren't accessible outside of rxrpc anyway. This seems to cut a bit of time out of the time elapsed between each sk_buff being timestamped and turning up in rxrpc (the final number in the following trace excerpts). I measured this by making the rxrpc_rx_packet trace point print the time elapsed between the skb being timestamped and the current time (in ns), e.g.: ... 424.278721: rxrpc_rx_packet: ...

tc: Add support for configuring the taprio scheduler
This traffic scheduler allows traffic classes states (transmission
allowed/not allowed, in the simplest case) to be scheduled, according
to a pre-generated time sequence. This is the basis of the IEEE
802.1Qbv specification.
Example configuration:
tc qdisc replace dev enp3s0 parent root handle 100 taprio \
num_tc 3 \
map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 \
queues 1@0 1@1 2@2 \
base-time 1528743495910289987 \
sched-entry S 01 300000 \
sched-entry S 02 300000 \
sched-entry S 04 300000 \
clockid CLOCK_TAI
The configuration format is similar to mqprio. The main difference is
the presence of a schedule, built by multiple "sched-entry"
definitions, each entry has the following format:
sched-entry <CMD> <GATE MASK> <INTERVAL>
The only supported <CMD> is "S", which means "SetGateStates",
following the IEEE 802.1Qbv-2015 definition (Table 8-6). <GATE MASK>
is a bitmask where each bit is a associated with a traffic class, so
bit 0 (the least significant bit) being "on" means that traffic class
0 is "active" for that schedule entry. <INTERVAL> is a time duration
in nanoseconds that specifies for how long that state defined by <CMD>
and <GATE MASK> should be held before moving to the next entry.
This schedule is circular, that is, after the last entry is executed
it starts from the first one, indefinitely.
The other parameters can be defined as follows:
- base-time: specifies the instant when the schedule starts, if
'base-time' is a time in the past, the schedule will start at
base-time + (N * cycle-time)
where N is the smallest integer so the resulting time is greater
than "now", and "cycle-time" is the sum of all the intervals of the
entries in the schedule;
- clockid: specifies the reference clock to be used;
The parameters should be similar to what the IEEE 802.1Q family of
specification defines.

dns: Allow the dns resolver to retrieve a server set
Allow the DNS resolver to retrieve a set of servers and their associated
addresses, ports, preference and weight ratings.
In terms of communication with userspace, "srv=1" is added to the callout
string (the '1' indicating the maximum data version supported by the
kernel) to ask the userspace side for this.
If the userspace side doesn't recognise it, it will ignore the option and
return the usual text address list.
If the userspace side does recognise it, it will return some binary data
that begins with a zero byte that would cause the string parsers to give an
error. The second byte contains the version of the data in the blob (this
may be between 1 and the version specified in the callout data). The
remainder of the payload is version-specific.
In version 1, the payload looks like (note that this is packed):
u8 Non-string marker (ie. 0)
u8 Content (0 => Server list)
u8 Version (ie. 1)
u8 Source (eg. DNS_RECORD_FROM_DNS_SRV)
u8 Status (eg. DNS_LOOKUP_GOOD)
u8 Number of servers
foreach-server {
u16 Name length (LE)
u16 Priority (as per SRV record) (LE)
u16 Weight (as per SRV record) (LE)
u16 Port (LE)
u8 Source (eg. DNS_RECORD_FROM_NSS)
u8 Status (eg. DNS_LOOKUP_GOT_NOT_FOUND)
u8 Protocol (eg. DNS_SERVER_PROTOCOL_UDP)
u8 Number of addresses
char[] Name (not NUL-terminated)
foreach-address {
u8 Family (AF_INET{,6})
union {
u8[4] ipv4_addr
u8[16] ipv6_addr
}
}
}
This can then be used to fetch a whole cell's VL-server configuration for
AFS, for example.
