Our virtual machines make use of device assignment by configuring
12 NVMe disks for high I/O performance. Each NVMe device has 129
MSI-X Table entries:
Capabilities: [50] MSI-X: Enable+ Count=129 Masked-Vector table: BAR=0 offset=00002000
The windows virtual machines fail to boot since they will map the number of
MSI-table entries that the NVMe hardware reported to the bus to msi routing
table, this will exceed the 1024. This patch extends MAX_IRQ_ROUTES to 4096
for all archs, in the future this might be extended again if needed.

This patch adds support to APR bus (Asynchronous Packet Router) driver.
APR driver is made as a bus driver so that the apr devices can added removed
more dynamically depending on the state of the services on the dsp.
APR is used for communication between application processor and QDSP to
use services on QDSP like Audio and others.

Some controllers are exposing high-level interfaces to access various
kind of SPI memories. Unfortunately they do not fit in the current
spi_controller model and usually have drivers placed in
drivers/mtd/spi-nor which are only supporting SPI NORs and not SPI
memories in general.
This is an attempt at defining a SPI memory interface which works for
all kinds of SPI memories (NORs, NANDs, SRAMs).

The sbitmap queue wake batch is calculated such that once allocations
start blocking, all of the bits which are already allocated must be
enough to fulfill the batch counters of all of the waitqueues. However,
the shallow allocation depth can break this invariant, since we block
before our full depth is being utilized. Add
sbitmap_queue_min_shallow_depth(), which saves the minimum shallow depth
the sbq will use, and update sbq_calc_wake_batch() to take it into

This patch gives an ID to each loaded BTF. The ID is allocated by
the idr like the existing prog-id and map-id.
The bpf_put(map->btf) is moved to __bpf_map_put() so that the
userspace can stop seeing the BTF ID ASAP when the last BTF
refcnt is gone.
It also makes BTF accessible from userspace through the
1. new BPF_BTF_GET_FD_BY_ID command. It is limited to CAP_SYS_ADMIN
which is inline with the BPF_BTF_LOAD cmd and the existing
BPF_[MAP|PROG]_GET_FD_BY_ID cmd.
2. new btf_id (and btf_key_id + btf_value_id) in "struct bpf_map_info"
Once the BTF ID handler is accessible from userspace, freeing a BTF
object has to go through a rcu period. The BPF_BTF_GET_FD_BY_ID cmd
can then be done under a rcu_read_lock() instead of taking
spin_lock.
[Note: A similar rcu usage can be done to the existing
bpf_prog_get_fd_by_id() in a follow up patch]
When processing the BPF_BTF_GET_FD_BY_ID cmd,
refcount_inc_not_zero() is needed because the BTF object
could be already in the rcu dead row . btf_get() is
removed since its usage is currently limited to btf.c
alone. refcount_inc() is used directly instead.

Currently, struct request has four timestamp fields:
- A start time, set at get_request time, in jiffies, used for iostats
- An I/O start time, set at start_request time, in ktime nanoseconds,
used for blk-stats (i.e., wbt, kyber, hybrid polling)
- Another start time and another I/O start time, used for cfq and bfq
These can all be consolidated into one start time and one I/O start
time, both in ktime nanoseconds, shaving off up to 16 bytes from struct
request depending on the kernel config.

Add support for the BCM43364 chipset via an SDIO interface, as used in
e.g. the Murata 1FX module.
The BCM43364 uses the same firmware as the BCM43430 (which is already
included), the only difference is the omission of Bluetooth.
However, the SDIO_ID for the BCM43364 is 02D0:A9A4, giving it a MODALIAS
of sdio:c00v02D0dA9A4, which doesn't get recognised and hence doesn't
load the brcmfmac module. Adding the 'A9A4' ID in the appropriate place
triggers the brcmfmac driver to load, and then correctly use the
firmware file 'brcmfmac43430-sdio.bin'.

This implements of_genpd_opp_to_performance_state() which can be used
from the device drivers or the OPP core to find the performance state
encoded in the "required-opps" property of a node. Normally this would
be called only once for each OPP of the device for which the OPP table
of the device is getting generated.
Different platforms may encode the performance state differently using
the OPP table (they may simply return value of opp-hz or opp-microvolt,
or apply some algorithm on top of those values) and so a new callback
->opp_to_performance_state() is implemented to allow platform specific

While trying to unify the pkey handling in show_smap() between x86 and
powerpc we stumbled across various build failures due to the order of
includes between the two arches.
Part of the problem is that linux/pkeys.h includes asm/mmu_context.h,
and the relationship between asm/mmu_context.h and asm/pkeys.h is not
consistent between the two arches.
It would be cleaner if linux/pkeys.h only included asm/pkeys.h,
creating a single integration point for the arch pkey definitions.
So this patch removes the include of asm/mmu_context.h from
linux/pkeys.h.
We can't prove that this is safe in the general case, but it passes
all the build tests I've thrown at it. Also asm/mmu_context.h is
included widely while linux/pkeys.h is not, so most likely any code
that is including linux/pkeys.h is already getting asm/mmu_context.h
from elsewhere.

Most mainstream architectures are using 65536 entries, so lets stick to
that. If someone is really desperate to override it that can still be
done through <asm/dma-mapping.h>, but I'd rather see a really good
rationale for that.
dma_debug_init is now called as a core_initcall, which for many
architectures means much earlier, and provides dma-debug functionality
earlier in the boot process. This should be safe as it only relies
on the memory allocator already being available.

It's rather common that a firmware is loaded into an SDIO func device
memory, by the corresponding SDIO func driver during ->probe() time.
However, to actually start running the new firmware, sometimes a soft reset
(no power cycle) and a re-initialization of the card is needed. This is for
example the case with the Espressif ESP8089 WiFi chips, when connected to
an SDIO interface.
To cope with this scenario, let's add a new exported function,
mmc_sw_reset(), which may be called when a soft reset and re-initialization
of the card are needed.
The mmc_sw_reset() is implemented on top of a new bus ops callback, similar
to how the mmc_hw_reset() has been implemented.

Seccomp logging for "handled" actions such as RET_TRAP, RET_TRACE, or
RET_ERRNO can be very noisy for processes that are being audited. This
patch modifies the seccomp logging behavior to treat processes that are
being inspected via the audit subsystem the same as processes that
aren't under inspection. Handled actions will no longer be logged just
because the process is being inspected. Since v4.14, applications have
the ability to request logging of handled actions by using the
SECCOMP_FILTER_FLAG_LOG flag when loading seccomp filters.
With this patch, the logic for deciding if an action will be logged is:
if action == RET_ALLOW:
do not log
else if action not in actions_logged:
do not log
else if action == RET_KILL:
log
else if action == RET_LOG:
log
else if filter-requests-logging:

The decision to log a seccomp action will always be subject to the
value of the kernel.seccomp.actions_logged sysctl, even for processes
that are being inspected via the audit subsystem, in an upcoming patch.
Therefore, we need to emit an audit record on attempts at writing to the
actions_logged sysctl when auditing is enabled.
This patch updates the write handler for the actions_logged sysctl to
emit an audit record on attempts to write to the sysctl. Successful
writes to the sysctl will result in a record that includes a normalized
list of logged actions in the "actions" field and a "res" field equal to
1. Unsuccessful writes to the sysctl will result in a record that
doesn't include the "actions" field and has a "res" field equal to 0.
Not all unsuccessful writes to the sysctl are audited. For example, an
audit record will not be emitted if an unprivileged process attempts to
open the sysctl file for reading since that access control check is not
part of the sysctl's write handler.
Below are some example audit records when writing various strings to the
actions_logged sysctl.
Writing "not-a-real-action", when the kernel.seccomp.actions_logged
sysctl previously was "kill_process kill_thread trap errno trace log",
emits this audit record:
type=CONFIG_CHANGE msg=audit(1525392371.454:120): op=seccomp-logging
actions=? old-actions=kill_process,kill_thread,trap,errno,trace,log
res=0
If you then write "kill_process kill_thread errno trace log", this audit
record is emitted:
type=CONFIG_CHANGE msg=audit(1525392401.645:126): op=seccomp-logging
actions=kill_process,kill_thread,errno,trace,log
old-actions=kill_process,kill_thread,trap,errno,trace,log res=1
If you then write "log log errno trace kill_process kill_thread", which
is unordered and contains the log action twice, it results in the same
actions value as the previous record:
type=CONFIG_CHANGE msg=audit(1525392436.354:132): op=seccomp-logging
actions=kill_process,kill_thread,errno,trace,log
old-actions=kill_process,kill_thread,errno,trace,log res=1
If you then write an empty string to the sysctl, this audit record is
emitted:
type=CONFIG_CHANGE msg=audit(1525392494.413:138): op=seccomp-logging
actions=(none) old-actions=kill_process,kill_thread,errno,trace,log
res=1
No audit records are generated when reading the actions_logged sysctl.

When the core networking needs to detect the transport offset in a given
packet and parse it explicitly, a full-blown flow_keys struct is used for
storage.
This patch introduces a smaller keys store, rework the basic flow dissect
helper to use it, and apply this new helper where possible - namely in
skb_probe_transport_header(). The used flow dissector data structures
are renamed to match more closely the new role.
The above gives ~50% performance improvement in micro benchmarking around
skb_probe_transport_header() and ~30% around eth_get_headlen(), mostly due
to the smaller memset. Small, but measurable improvement is measured also
in macro benchmarking.
v1 -> v2: use the new helper in eth_get_headlen() and skb_get_poff(),
as per DaveM suggestion

This was used by the ide, scsi and networking code in the past to
determine if they should bounce payloads. Now that the dma mapping
always have to support dma to all physical memory (thanks to swiotlb
for non-iommu systems) there is no need to this crude hack any more.

ide_toggle_bounce did select various strange block bounce limits, including
not bouncing at all as soon as an iommu is present in the system. Given
that the dma_map routines now handle any required bounce buffering except
for ISA DMA, and the ide code already must handle either ISA DMA or highmem
at least for iommu equipped systems we can get rid of the block layer
bounce limit setting entirely.

====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for your net-next
tree, more relevant updates in this batch are:
1) Add Maglev support to IPVS. Moreover, store lastest server weight in
IPVS since this is needed by maglev, patches from from Inju Song.
2) Preparation works to add iptables flowtable support, patches
from Felix Fietkau.
3) Hand over flows back to conntrack slow path in case of TCP RST/FIN
packet is seen via new teardown state, also from Felix.
4) Add support for extended netlink error reporting for nf_tables.
5) Support for larger timeouts that 23 days in nf_tables, patch from
Florian Westphal.
6) Always set an upper limit to dynamic sets, also from Florian.
7) Allow number generator to make map lookups, from Laura Garcia.
8) Use hash_32() instead of opencode hashing in IPVS, from Vicent Bernat.
9) Extend ip6tables SRH match to support previous, next and last SID,
from Ahmed Abdelsalam.
10) Move Passive OS fingerprint nf_osf.c, from Fernando Fernandez.
11) Expose nf_conntrack_max through ctnetlink, from Florent Fourcot.
12) Several housekeeping patches for xt_NFLOG, x_tables and ebtables,
from Taehee Yoo.
13) Unify meta bridge with core nft_meta, then make nft_meta built-in.
Make rt and exthdr built-in too, again from Florian.
14) Missing initialization of tbl->entries in IPVS, from Cong Wang.
