when passed to helper functions
- fix mount source displayed for bpffs (none -> bpffs)
- bonding:
- fix extraction of ports for connection hash calculation
- fix bond_xmit_broadcast return value when some devices are down
- phy: marvell: add Marvell specific PHY loopback

tools/testing/selftests/bpf: replace open-coded 16 with TASK_COMM_LEN
As the sched:sched_switch tracepoint args are derived from the kernel, we'd better make it same with the kernel. So the macro TASK_COMM_LEN is converted to type enum, then all the BPF programs can get it through BTF. The BPF program which wants to use TASK_COMM_LEN should include the header vmlinux.h. Regarding the test_stacktrace_map and test_tracepoint, as the type defined in linux/bpf.h are also defined in vmlinux.h, so we don't need to include linux/bpf.h again.

mm/hmm.c: allow VM_MIXEDMAP to work with hmm_range_fault
hmm_range_fault() can be used instead of get_user_pages() for devices
which allow faulting however unlike get_user_pages() it will return an
error when used on a VM_MIXEDMAP range.
To make hmm_range_fault() more closely match get_user_pages() remove
this restriction. This requires dealing with the !ARCH_HAS_PTE_SPECIAL
case in hmm_vma_handle_pte(). Rather than replicating the logic of
vm_normal_page() call it directly and do a check for the zero pfn
similar to what get_user_pages() currently does.
Also add a test to hmm selftest to verify functionality.

selftests/vm: make charge_reserved_hugetlb.sh work with existing cgroup setting
The hugetlb cgroup reservation test charge_reserved_hugetlb.sh assume
that no cgroup filesystems are mounted before running the test. That is
not true in many cases. As a result, the test fails to run. Fix that
by querying the current cgroup mount setting and using the existing
cgroup setup instead before attempting to freshly mount a cgroup
filesystem.
Similar change is also made for hugetlb_reparenting_test.sh as well,
though it still has problem if cgroup v2 isn't used.
The patched test scripts were run on a centos 8 based system to verify
that they ran properly.

mm, hugepages: make memory size variable in hugepage-mremap selftest
The hugetlb vma mremap() test currently maps 1GB of memory to trigger pmd sharing and make sure that 'unshare' path in mremap code works. The test originally only mapped 10MB of memory (as specified by the header comment) but was later modified to 1GB to tackle this case. However, not all machines will have 1GB of memory to spare for this test. Adding a mapping size arg will allow run_vmtest.sh to pass an adequate mapping size, while allowing users to run the test independently with arbitrary size mappings.

selftest: kvm: Add amx selftest
This selftest covers two aspects of AMX. The first is triggering #NM exception and checking the MSR XFD_ERR value. The second case is loading tile config and tile data into guest registers and trapping to the host side for a complete save/load of the guest state. TMM0 is also checked against memory data after save/restore.

selftest: kvm: Reorder vcpu_load_state steps for AMX
For AMX support it is recommended to load XCR0 after XFD, so that KVM does not see XFD=0, XCR=1 for a save state that will eventually be disabled (which would lead to premature allocation of the space required for that save state). It is also required to load XSAVE data after XCR0 and XFD, so that KVM can trigger allocation of the extra space required to store AMX state. Adjust vcpu_load_state to obey these new requirements.

sound updates for 5.17-rc1
It's a relatively calm development cycle, but still lots of updates in
the driver side like Intel SOF. Below are some highlights:
* ALSA / ASoC core:
- A new kselftest for ALSA control API
- PCM NO_REWINDS support
- Potential race fixes around control removals
- Unify x86 SG-buffer memory allocation code
- Cleanups and race fixes for ASoC DPCM locking
* ASoC:
- Refinements and cleanups around the delay() APIs
- Wider use of dev_err_probe().
- Continuing cleanups and improvements to the SOF code
- Support for pin switches in simple-card derived cards
- Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel
systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20
S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments
TLV320ADC3xxx
* HD-audio / USB-audio:
- Fix deadlock at HD-audio codec unbinding
- Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec
- Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device
* Misc:
- Fix virmidi drain behavior
Note that the merge of CS35L41 codec support is still half-baked, and
at least one ACPI change is missing. Although this won't hinder the
kernel build itself, we're going to catch up before RC1.

Merge tag 'libnvdimm-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull dax and libnvdimm updates from Dan Williams:
"The bulk of this is a rework of the dax_operations API after
discovering the obstacles it posed to the work-in-progress DAX+reflink
support for XFS and other copy-on-write filesystem mechanics.
Primarily the need to plumb a block_device through the API to handle
partition offsets was a sticking point and Christoph untangled that
dependency in addition to other cleanups to make landing the
DAX+reflink support easier.
The DAX_PMEM_COMPAT option has been around for 4 years and not only
are distributions shipping userspace that understand the current
configuration API, but some are not even bothering to turn this option
on anymore, so it seems a good time to remove it per the deprecation
schedule. Recall that this was added after the device-dax subsystem
moved from /sys/class/dax to /sys/bus/dax for its sysfs organization.
All recent functionality depends on /sys/bus/dax.
Some other miscellaneous cleanups and reflink prep patches are
included as well.
Summary:
- Simplify the dax_operations API:
- Eliminate bdev_dax_pgoff() in favor of the filesystem
maintaining and applying a partition offset to all its DAX iomap
operations.
- Remove wrappers and device-mapper stacked callbacks for
->copy_from_iter() and ->copy_to_iter() in favor of moving

Pull gpio updates from Bartosz Golaszewski:
"The gpio-sim module is back, this time without any changes to
configfs. This results in a less elegant user-space interface but I
never got any follow-up on the committable items and didn't want to
delay this module for several more months.
Other than that we have support for several new models and some
support going away. We started working on converting GPIO drivers to
using fwnode exclusively in order to limit references to OF symbols to
gpiolib-of.c exclusively. We also have regular tweaks and improvements
all over the place.

Networking changes for 5.17.
Core
----
- Defer freeing TCP skbs to the BH handler, whenever possible,
or at least perform the freeing outside of the socket lock section
to decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice
and net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.
- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF
---
- New helpers:
- bpf_find_vma(), find and inspect VMAs for profiling use cases
- bpf_loop(), runtime-bounded loop helper trading some execution
time for much faster (if at all converging) verification
- bpf_strncmp(), improve performance, avoid compiler flakiness
- bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
for tracing programs, all inlined by the verifier
- Support BPF relocations (CO-RE) in the kernel loader.
- Further the support for BTF_TYPE_TAG annotations.
- Allow access to local storage in sleepable helpers.
- Convert verifier argument types to a composable form with different
attributes which can be shared across types (ro, maybe-null).
- Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
creating new, extensible ones where missing and deprecating those
to be removed.
Protocols
---------
- WiFi (mac80211/cfg80211):
- notify user space about long "come back in N" AP responses,
allow it to react to such temporary rejections
- allow non-standard VHT MCS 10/11 rates
- use coarse time in airtime fairness code to save CPU cycles
- Bluetooth:
- rework of HCI command execution serialization to use a common
queue and work struct, and improve handling errors reported
in the middle of a batch of commands

- support fastclose option (quick shutdown of the full MPTCP
connection, similar to TCP RST in regular TCP)
- MCTP (Management Component Transport) over serial, as defined by
DMTF spec DSP0253 - "MCTP Serial Transport Binding".
Driver API
----------
- Support timestamping on bond interfaces in active/passive mode.
- Introduce generic phylink link mode validation for drivers which
don't have any quirks and where MAC capability bits fully express
what's supported. Allow PCS layer to participate in the validation.
Convert a number of drivers.
- Add support to set/get size of buffers on the Rx rings and size of
the tx copybreak buffer via ethtool.
- Support offloading TC actions as first-class citizens rather than
only as attributes of filters, improve sharing and device resource
utilization.
- WiFi (mac80211/cfg80211):
- support forwarding offload (ndo_fill_forward_path)
- support for background radar detection hardware
- SA Query Procedures offload on the AP side

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next. This
includes one patch to update ovs and act_ct to use nf_ct_put() instead
of nf_conntrack_put().
1) Add netns_tracker to nfnetlink_log and masquerade, from Eric Dumazet.
2) Remove redundant rcu read-size lock in nf_tables packet path.
3) Replace BUG() by WARN_ON_ONCE() in nft_payload.
4) Consolidate rule verdict tracing.
5) Replace WARN_ON() by WARN_ON_ONCE() in nf_tables core.
6) Make counter support built-in in nf_tables.
7) Add new field to conntrack object to identify locally generated
traffic, from Florian Westphal.
8) Prevent NAT from shadowing well-known ports, from Florian Westphal.
9) Merge nf_flow_table_{ipv4,ipv6} into nf_flow_table_inet, also from
Florian.
10) Remove redundant pointer in nft_pipapo AVX2 support, from Colin Ian King.
11) Replace opencoded max() in conntrack, from Jiapeng Chong.
12) Update conntrack to use refcount_t API, from Florian Westphal.
13) Move ip_ct_attach indirection into the nf_ct_hook structure.
14) Constify several pointer object in the netfilter codebase,
from Florian Westphal.
15) Tree-wide replacement of nf_conntrack_put() by nf_ct_put(), also
from Florian.
16) Fix egress splat due to incorrect rcu notation, from Florian.
17) Move stateful fields of connlimit, last, quota, numgen and limit
out of the expression data area.
18) Build a blob to represent the ruleset in nf_tables, this is a
requirement of the new register tracking infrastructure.
19) Add NFT_REG32_NUM to define the maximum number of 32-bit registers.
20) Add register tracking infrastructure to skip redundant
store-to-register operations, this includes support for payload,
meta and bitwise expresssions.

selftests: mptcp: more stable join tests-cases
MPTCP join self-tests are a bit fragile as they reply on delays instead of events to catch-up with the expected sockets states. Replace the delay with state checking where possible and reduce the number of sleeps in the most complex scenarios. This will both reduce the tests run-time and will improve stability.

kvm: selftests: move base kvm_util.h declarations to kvm_util_base.h
Between helper macros and interfaces that will be introduced in subsequent patches, much of kvm_util.h would end up being declarations specific to ucall. Ideally these could be separated out into a separate header since they are not strictly required for writing guest tests and are mostly self-contained interfaces other than a reliance on a few core declarations like struct kvm_vm. This doesn't make a big difference as far as how tests will be compiled/written since all these interfaces will still be packaged up into a single/common libkvm.a used by all tests, but it is still nice to be able to compartmentalize to improve readabilty and reduce merge conflicts in the future for common tasks like adding new interfaces to kvm_util.h. Furthermore, some of the ucall declarations will be arch-specific, requiring various #ifdef'ery in kvm_util.h. Ideally these declarations could live in separate arch-specific headers, e.g. include/<arch>/ucall.h, which would handle arch-specific declarations as well as pulling in common ucall-related declarations shared by all archs. One simple way to do this would be to #include ucall.h at the bottom of kvm_util.h, after declarations it relies upon like struct kvm_vm. This is brittle however, and doesn't scale easily to other sets of interfaces that may be added in the future. Instead, move all declarations currently in kvm_util.h into kvm_util_base.h, then have kvm_util.h #include it. With this change, non-base declarations can be selectively moved/introduced into separate headers, which can then be included in kvm_util.h so that individual tests don't need to be touched. Subsequent patches will then move ucall-related declarations into a separate header to meet the above goals.

KVM: x86/xen: Add KVM_IRQ_ROUTING_XEN_EVTCHN and event channel delivery
This adds basic support for delivering 2 level event channels to a guest. Initially, it only supports delivery via the IRQ routing table, triggered by an eventfd. In order to do so, it has a kvm_xen_set_evtchn_fast() function which will use the pre-mapped shared_info page if it already exists and is still valid, while the slow path through the irqfd_inject workqueue will remap the shared_info page if necessary. It sets the bits in the shared_info page but not the vcpu_info; that is deferred to __kvm_xen_has_interrupt() which raises the vector to the appropriate vCPU. Add a 'verbose' mode to xen_shinfo_test while adding test cases for this.

selftests: KVM: sev_migrate_tests: Fix sev_ioctl()
TEST_ASSERT in SEV ioctl was allowing errors because it checked return value was good OR the FW error code was OK. This TEST_ASSERT should require both (aka. AND) values are OK. Removes the LAUNCH_START from the mirror VM because this call correctly fails because mirror VMs cannot call this command. Currently issues with the PSP driver functions mean the firmware error is not always reset to SEV_RET_SUCCESS when a call is successful. Mainly sev_platform_init() doesn't correctly set the fw error if the platform has already been initialized.

KVM/arm64 updates for Linux 5.16
- Simplification of the 'vcpu first run' by integrating it into KVM's 'pid change' flow - Refactoring of the FP and SVE state tracking, also leading to a simpler state and less shared data between EL1 and EL2 in the nVHE case - Tidy up the header file usage for the nvhe hyp object - New HYP unsharing mechanism, finally allowing pages to be unmapped from the Stage-1 EL2 page-tables - Various pKVM cleanups around refcounting and sharing - A couple of vgic fixes for bugs that would trigger once the vcpu xarray rework is merged, but not sooner - Add minimal support for ARMv8.7's PMU extension - Rework kvm_pgtable initialisation ahead of the NV work - New selftest for IRQ injection - Teach selftests about the lack of default IPA space and page sizes - Expand sysreg selftest to deal with Pointer Authentication - The usual bunch of cleanups and doc update -----BEGIN PGP SIGNATURE----- iQJDBAABCgAtFiEEn9UcU+C1Yxj9lZw9I9DQutE9ekMFAmHYIpgPHG1hekBrZXJu ZWwub3JnAAoJECPQ0LrRPXpDndsP/RsBmX6bmQnDEhaaqfGAxOETyq/my1eT9r/V 3Ax4fEqSFfD5yHbYvqNRC8ueycH4r8WAr4ACWDAI6XpS/pYx00nx2N+HCSgjGyQR FeXqITuGPEsn4NkGuPci0PFmI8rVUzanl1ugRGQAETVrZo2ZVH2uqKVGT8XOlu0J FB/0x6Z4vMuIgEXyfa+DZ8WdW1aCRgPU2oyOdSdWE57/grjyLJqk6EdMmLyaQ19E vz6vXuRnA/GQwOtByqYEnQ8a4VXsQedCMqg/f9mj0BxpDzxC1ps8Nrpv36aJXKUN LEXapP9bCWPW9LqaKAOZnQYrUIIEFHsCUom0n3reDHrgObA+jivpz75L8GEr3CdC Bv78N04Yymjpp2WA6CuO3r9HjL1nJ6tYqobXU2pvqln4nNC3Ukucjq9ZVuWgS6Hx qOZXgPcZ/HpS3l/U+dAu8yIcV2SchQXDudaq8BsfLd8M1bD+oirSBolZFSvz7MYZ 6+jtEDLUOEO5s4rXiJF46+MauxiELcjaewAEK4WwrS8NBwEyhYe9EPsYcQ5pcrQF QwAd1+y7oLfhpGHv5KJKWswfvbtlLCm6NOAhawq0UXM8bS+79tu0dGjiDzVPBuSf SyA3VtBSKxcpvCrljw9ubtjxvKrviE0MDvlmTP2B1NU+lwm8xRBiwUwOH29qP9zU HDeUj2fy =HkZk -----END PGP SIGNATURE----- Merge tag 'kvmarm-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 updates for Linux 5.16 - Simplification of the 'vcpu first run' by integrating it into KVM's 'pid change' flow - Refactoring of the FP and SVE state tracking, also leading to a simpler state and less shared data between EL1 and EL2 in the nVHE case - Tidy up the header file usage for the nvhe hyp object - New HYP unsharing mechanism, finally allowing pages to be unmapped from the Stage-1 EL2 page-tables - Various pKVM cleanups around refcounting and sharing - A couple of vgic fixes for bugs that would trigger once the vcpu xarray rework is merged, but not sooner - Add minimal support for ARMv8.7's PMU extension - Rework kvm_pgtable initialisation ahead of the NV work - New selftest for IRQ injection - Teach selftests about the lack of default IPA space and page sizes - Expand sysreg selftest to deal with Pointer Authentication - The usual bunch of cleanups and doc update |

mptcp: keep track of local endpoint still available for each msk
Include into the path manager status a bitmap tracking the list of local endpoints still available - not yet used - for the relevant mptcp socket. Keep such map updated at endpoint creation/deletion time, so that we can easily skip already used endpoint at local address selection time. The endpoint used by the initial subflow is lazyly accounted at subflow creation time: the usage bitmap is be up2date before endpoint selection and we avoid such unneeded task in some relevant scenarios - e.g. busy servers accepting incoming subflows but not creating any additional ones nor annuncing additional addresses. Overall this allows for fair local endpoints usage in case of subflow failure. As a side effect, this patch also enforces that each endpoint is used at most once for each mptcp connection.
