perf/mem: Rename PERF_MEM_LVLNUM_EXTN_MEM to PERF_MEM_LVLNUM_CXL
PERF_MEM_LVLNUM_EXTN_MEM was introduced to cover CXL devices but it's bit ambiguous name and also not generic enough to cover cxl.cache and cxl.io devices. Rename it to PERF_MEM_LVLNUM_CXL to be more specific.

bpf: Implement cgroup storage available to non-cgroup-attached bpf progs
Similar to sk/inode/task storage, implement similar cgroup local storage.
There already exists a local storage implementation for cgroup-attached
bpf programs. See map type BPF_MAP_TYPE_CGROUP_STORAGE and helper
bpf_get_local_storage(). But there are use cases such that non-cgroup
attached bpf progs wants to access cgroup local storage data. For example,
tc egress prog has access to sk and cgroup. It is possible to use
sk local storage to emulate cgroup local storage by storing data in socket.
But this is a waste as it could be lots of sockets belonging to a particular
cgroup. Alternatively, a separate map can be created with cgroup id as the key.
But this will introduce additional overhead to manipulate the new map.
A cgroup local storage, similar to existing sk/inode/task storage,
should help for this use case.
The life-cycle of storage is managed with the life-cycle of the
cgroup struct. i.e. the storage is destroyed along with the owning cgroup
with a call to bpf_cgrp_storage_free() when cgroup itself
is deleted.
The userspace map operations can be done by using a cgroup fd as a key
passed to the lookup, update and delete operations.
Typically, the following code is used to get the current cgroup:
struct task_struct *task = bpf_get_current_task_btf();
... task->cgroups->dfl_cgrp ...
and in structure task_struct definition:
struct task_struct {
....
struct css_set __rcu *cgroups;
....
}
With sleepable program, accessing task->cgroups is not protected by rcu_read_lock.
So the current implementation only supports non-sleepable program and supporting
sleepable program will be the next step together with adding rcu_read_lock
protection for rcu tagged structures.
Since map name BPF_MAP_TYPE_CGROUP_STORAGE has been used for old cgroup local
storage support, the new map name BPF_MAP_TYPE_CGRP_STORAGE is used
for cgroup storage available to non-cgroup-attached bpf programs. The old
cgroup storage supports bpf_get_local_storage() helper to get the cgroup data.
The new cgroup storage helper bpf_cgrp_storage_get() can provide similar
functionality. While old cgroup storage pre-allocates storage memory, the new
mechanism can also pre-allocate with a user space bpf_map_update_elem() call
to avoid potential run-time memory allocation failure.
Therefore, the new cgroup storage can provide all functionality w.r.t.
the old one. So in uapi bpf.h, the old BPF_MAP_TYPE_CGROUP_STORAGE is alias to
BPF_MAP_TYPE_CGROUP_STORAGE_DEPRECATED to indicate the old cgroup storage can
be deprecated since the new one can provide the same functionality.

netfilter: nft_inner: support for inner tunnel header matching
This new expression allows you to match on the inner headers that are encapsulated by any of the existing tunneling protocols. This expression parses the inner packet to set the link, network and transport offsets, so the existing expressions (with a few updates) can be reused to match on the inner headers. The inner expression supports for different tunnel combinations such as: - ethernet frame over IPv4/IPv6 packet, eg. VxLAN. - IPv4/IPv6 packet over IPv4/IPv6 packet, eg. IPIP. - IPv4/IPv6 packet over IPv4/IPv6 + transport header, eg. GRE. - transport header (ESP or SCTP) over transport header (usually UDP) The following fields are used to describe the tunnel protocol: - flags, which describe how to parse the inner headers: NFT_PAYLOAD_CTX_INNER_TUN, the tunnel provides its own header. NFT_PAYLOAD_CTX_INNER_ETHER, the ethernet frame is available as inner header. NFT_PAYLOAD_CTX_INNER_NH, the network header is available as inner header. NFT_PAYLOAD_CTX_INNER_TH, the transport header is available as inner header. For example, VxLAN sets on all of these flags. While GRE only sets on NFT_PAYLOAD_CTX_INNER_NH and NFT_PAYLOAD_CTX_INNER_TH. Then, ESP over UDP only sets on NFT_PAYLOAD_CTX_INNER_TH. The tunnel description is composed of the following attributes: - header size: in case the tunnel comes with its own header, eg. VxLAN. - type: this provides a hint to userspace on how to delinearize the rule. This is useful for VxLAN and Geneve since they run over UDP, since transport does not provide a hint. This is also useful in case hardware offload is ever supported. The type is not currently interpreted by the kernel. - expression: currently only payload supported. Follow up patch adds also inner meta support which is required by autogenerated dependencies. The exthdr expression should be supported too at some point. There is a new inner_ops operation that needs to be set on to allow to use an existing expression from the inner expression. This patch adds a new NFT_PAYLOAD_TUN_HEADER base which allows to match on the tunnel header fields, eg. vxlan vni. The payload expression is embedded into nft_inner private area and this private data area is passed to the payload inner eval function via direct call.

Merge tag 'media/v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull missed media updates from Mauro Carvalho Chehab:
"It seems I screwed-up my previous pull request: it ends up that only
half of the media patches that were in linux-next got merged in -rc1.
The script which creates the signed tags silently failed due to
5.19->6.0 so it ended generating a tag with incomplete stuff.
So here are the missing parts:
- a DVB core security fix
- lots of fixes and cleanups for atomisp staging driver
- old drivers that are VB1 are being moved to staging to be
deprecated
- several driver updates - mostly for embedded systems, but there are
also some things addressing issues with some PC webcams, in the UVC
video driver"

dmaengine: idxd: Do not enable user type Work Queue without Shared Virtual Addressing
When the idxd_user_drv driver is bound to a Work Queue (WQ) device
without IOMMU or with IOMMU Passthrough without Shared Virtual
Addressing (SVA), the application gains direct access to physical
memory via the device by programming physical address to a submitted
descriptor. This allows direct userspace read and write access to
arbitrary physical memory. This is inconsistent with the security
goals of a good kernel API.
Unlike vfio_pci driver, the IDXD char device driver does not provide any
ways to pin user pages and translate the address from user VA to IOVA or
PA without IOMMU SVA. Therefore the application has no way to instruct the
device to perform DMA function. This makes the char device not usable for
normal application usage.
Since user type WQ without SVA cannot be used for normal application usage
and presents the security issue, bind idxd_user_drv driver and enable user
type WQ only when SVA is enabled (i.e. user PASID is enabled).

VFIO updates for v6.1-rc1
- Prune private items from vfio_pci_core.h to a new internal header,
fix missed function rename, and refactor vfio-pci interrupt defines.
(Jason Gunthorpe)
- Create consistent naming and handling of ioctls with a function per
ioctl for vfio-pci and vfio group handling, use proper type args
where available. (Jason Gunthorpe)
- Implement a set of low power device feature ioctls allowing userspace
to make use of power states such as D3cold where supported.
(Abhishek Sahu)
- Remove device counter on vfio groups, which had restricted the page
pinning interface to singleton groups to account for limitations in
the type1 IOMMU backend. Document usage as limited to emulated IOMMU
devices, ie. traditional mdev devices where this restriction is
consistent. (Jason Gunthorpe)
- Correct function prefix in hisi_acc driver incurred during previous
refactoring. (Shameer Kolothum)
- Correct typo and remove redundant warning triggers in vfio-fsl driver.
(Christophe JAILLET)
- Introduce device level DMA dirty tracking uAPI and implementation in
the mlx5 variant driver (Yishai Hadas & Joao Martins)
- Move much of the vfio_device life cycle management into vfio core,
simplifying and avoiding duplication across drivers. This also
facilitates adding a struct device to vfio_device which begins the
introduction of device rather than group level user support and fills
a gap allowing userspace identify devices as vfio capable without
implicit knowledge of the driver. (Kevin Tian & Yi Liu)
- Split vfio container handling to a separate file, creating a more
well defined API between the core and container code, masking IOMMU
backend implementation from the core, allowing for an easier future
transition to an iommufd based implementation of the same.
(Jason Gunthorpe)
- Attempt to resolve race accessing the iommu_group for a device
between vfio releasing DMA ownership and removal of the device from
the IOMMU driver. Follow-up with support to allow vfio_group to
exist with NULL iommu_group pointer to support existing userspace
use cases of holding the group file open. (Jason Gunthorpe)
- Fix error code and hi/lo register manipulation issues in the hisi_acc
variant driver, along with various code cleanups. (Longfang Liu)
- Fix a prior regression in GVT-g group teardown, resulting in
unreleased resources. (Jason Gunthorpe)
- A significant cleanup and simplification of the mdev interface,
consolidating much of the open coded per driver sysfs interface
support into the mdev core. (Christoph Hellwig)
- Simplification of tracking and locking around vfio_groups that
fall out from previous refactoring. (Jason Gunthorpe)
- Replace trivial open coded f_ops tests with new helper.

- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam R. Howlett. An overlapping range-based tree for vmas. It it apparently slight more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat (https://lkml.kernel.org/r/CAOUHufZabH85CeUN-MEMgL8gJGzJEWUrkiM58JkTbBhh-jew0Q@mail.gmail.com). This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses clang-generated instrumentation to detect used-unintialized bugs down to the single bit level. KMSAN keeps finding bugs. New ones, as well as the legacy ones. - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of memory into THPs. - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support file/shmem-backed pages. - userfaultfd updates from Axel Rasmussen - zsmalloc cleanups from Alexey Romanov - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure - Huang Ying adds enhancements to NUMA balancing memory tiering mode's page promotion, with a new way of detecting hot pages. - memcg updates from Shakeel Butt: charging optimizations and reduced memory consumption. - memcg cleanups from Kairui Song. - memcg fixes and cleanups from Johannes Weiner. - Vishal Moola provides more folio conversions - Zhang Yi removed ll_rw_block() :( - migration enhancements from Peter Xu - migration error-path bugfixes from Huang Ying - Aneesh Kumar added ability for a device driver to alter the memory tiering promotion paths.

and some new ids to enable new hardware devices
- USB gadget uvc updates for newer video formats and better v4l
integration (the v4l portions were acked by those maintainers)
- typec updates for tiny issues and more typec drivers for new
chips.
- xhci tiny updates for minor issues
- big usb-serial ftdi_sio driver update to handle new devices
better
- lots of tiny dwc3 fixes and updates for the IP block that is
showing up everywhere these days

virtio_blk: add SECURE ERASE command support
Support for the VIRTIO_BLK_F_SECURE_ERASE VirtIO feature. A device that offers this feature can receive VIRTIO_BLK_T_SECURE_ERASE commands. A device which supports this feature has the following fields in the virtio config: - max_secure_erase_sectors - max_secure_erase_seg - secure_erase_sector_alignment max_secure_erase_sectors and secure_erase_sector_alignment are expressed in 512-byte units. Every secure erase command has the following fields: - sectors: The starting offset in 512-byte units. - num_sectors: The number of sectors.

This patch allows the device features to be provisioned through netlink. A new attribute is introduced to allow the userspace to pass a 64bit device features during device adding. This provides several advantages: - Allow to provision a subset of the features to ease the cross vendor live migration. - Better debug-ability for vDPA framework and parent.

cfg80211: Update Transition Disable policy during port authorization
In case of 4way handshake offload, transition disable policy updated by the AP during EAPOL 3/4 is not updated to the upper layer. This results in mismatch between transition disable policy between the upper layer and the driver. This patch addresses this issue by updating transition disable policy as part of port authorization indication.

Pull btrfs updates from David Sterba:
"There's a bunch of performance improvements, most notably the FIEMAP
speedup, the new block group tree to speed up mount on large
filesystems, more io_uring integration, some sysfs exports and the
usual fixes and core updates.
Summary:
Performance:
- outstanding FIEMAP speed improvement
- algorithmic change how extents are enumerated leads to orders of
magnitude speed boost (uncached and cached)
- extent sharing check speedup (2.2x uncached, 3x cached)
- add more cancellation points, allowing to interrupt seeking in
files with large number of extents
- more efficient hole and data seeking (4x uncached, 1.3x cached)
- sample results:
256M, 32K extents: 4s -> 29ms (~150x)
512M, 64K extents: 30s -> 59ms (~550x)
1G, 128K extents: 225s -> 120ms (~1800x)
- improved inode logging, especially for directories (on dbench
workload throughput +25%, max latency -21%)
- improved buffered IO, remove redundant extent state tracking,
lowering memory consumption and avoiding rb tree traversal
- add sysfs tunable to let qgroup temporarily skip exact accounting
when deleting snapshot, leading to a speedup but requiring a rescan
after that, will be used by snapper
- support io_uring and buffered writes, until now it was just for
direct IO, with the no-wait semantics implemented in the buffered
write path it now works and leads to speed improvement in IOPS
(2x), throughput (2.2x), latency (depends, 2x to 150x)
- small performance improvements when dropping and searching for
extent maps as well as when flushing delalloc in COW mode
(throughput +5MB/s)
User visible changes:
- new incompatible feature block-group-tree adding a dedicated tree
for tracking block groups, this allows a much faster load during
mount and avoids seeking unlike when it's scattered in the extent
tree items
- this reduces mount time for many-terabyte sized filesystems
- conversion tool will be provided so existing filesystem can also
be updated in place
- to reduce test matrix and feature combinations requires no-holes
and free-space-tree (mkfs defaults since 5.15)
- improved reporting of super block corruption detected by scrub
- scrub also tries to repair super block and does not wait until next
commit
- discard stats and tunables are exported in sysfs
(/sys/fs/btrfs/FSID/discard)
- qgroup status is exported in sysfs
(/sys/sys/fs/btrfs/FSID/qgroups/)
- verify that super block was not modified when thawing filesystem
Fixes:
- FIEMAP fixes
- fix extent sharing status, does not depend on the cached status
where merged
- flush delalloc so compressed extents are reported correctly
- fix alignment of VMA for memory mapped files on THP
- send: fix failures when processing inodes with no links (orphan
files and directories)
- fix race between quota enable and quota rescan ioctl
- handle more corner cases for read-only compat feature verification
- fix missed extent on fsync after dropping extent maps
Core:
- lockdep annotations to validate various transactions states and
state transitions
- preliminary support for fs-verity in send
- more effective memory use in scrub for subpage where sector is
smaller than page
- block group caching progress logic has been removed, load is now
synchronous
- simplify end IO callbacks and bio handling, use chained bios
instead of own tracking
- add no-wait semantics to several functions (tree search, nocow,
flushing, buffered write
- cleanups and refactoring
MM changes:
- export balance_dirty_pages_ratelimited_flags"

ARM: driver updates for 6.1
The drivers branch for 6.1 is a bit larger than for most releases. Most
of the changes come from SoC maintainers for the drivers/soc subsystem:
- A new driver for error handling on the NVIDIA Tegra
'control backbone' bus.
- A new driver for Qualcomm LLCC/DDR bandwidth measurement
- New Rockchip rv1126 and rk3588 power domain drivers
- DT binding updates for memory controllers, older Rockchip
SoCs, various Mediatek devices, Qualcomm SCM firmware
- Minor updates to Hisilicon LPC bus, the Allwinner SRAM
driver, the Apple rtkit firmware driver, Tegra firmware
- Minor updates for SoC drivers (Samsung, Mediatek, Renesas,
Tegra, Qualcomm, Broadcom, NXP, ...)
There are also some separate subsystem with downstream maintainers that
merge updates this way:
- Various updates and new drivers in the memory controller
subsystem for Mediatek and Broadcom SoCs
- Small set of changes in preparation to add support for FF-A
v1.1 specification later, in the Arm FF-A firmware subsystem
- debugfs support in the PSCI firmware subsystem

bpf: explicitly define BPF_FUNC_xxx integer values
Historically enum bpf_func_id's BPF_FUNC_xxx enumerators relied on
implicit sequential values being assigned by compiler. This is
convenient, as new BPF helpers are always added at the very end, but it
also has its downsides, some of them being:
- with over 200 helpers now it's very hard to know what's each helper's ID,
which is often important to know when working with BPF assembly (e.g.,
by dumping raw bpf assembly instructions with llvm-objdump -d
command). it's possible to work around this by looking into vmlinux.h,
dumping /sys/btf/kernel/vmlinux, looking at libbpf-provided
bpf_helper_defs.h, etc. But it always feels like an unnecessary step
and one should be able to quickly figure this out from UAPI header.
- when backporting and cherry-picking only some BPF helpers onto older
kernels it's important to be able to skip some enum values for helpers
that weren't backported, but preserve absolute integer IDs to keep BPF
helper IDs stable so that BPF programs stay portable across upstream
and backported kernels.
While neither problem is insurmountable, they come up frequently enough
and are annoying enough to warrant improving the situation. And for the
backporting the problem can easily go unnoticed for a while, especially
if backport is done with people not very familiar with BPF subsystem overall.
Anyways, it's easy to fix this by making sure that __BPF_FUNC_MAPPER
macro provides explicit helper IDs. Unfortunately that would potentially
break existing users that use UAPI-exposed __BPF_FUNC_MAPPER and are
expected to pass macro that accepts only symbolic helper identifier
(e.g., map_lookup_elem for bpf_map_lookup_elem() helper).
As such, we need to introduce a new macro (___BPF_FUNC_MAPPER) which
would specify both identifier and integer ID, but in such a way as to
allow existing __BPF_FUNC_MAPPER be expressed in terms of new
___BPF_FUNC_MAPPER macro. And that's what this patch is doing. To avoid
duplication and allow __BPF_FUNC_MAPPER stay *exactly* the same,
___BPF_FUNC_MAPPER accepts arbitrary "context" arguments, which can be
used to pass any extra macros, arguments, and whatnot. In our case we
use this to pass original user-provided macro that expects single
argument and __BPF_FUNC_MAPPER is using it's own three-argument
__BPF_FUNC_MAPPER_APPLY intermediate macro to impedance-match new and
old "callback" macros.
Once we resolve this, we use new ___BPF_FUNC_MAPPER to define enum
bpf_func_id with explicit values. The other users of __BPF_FUNC_MAPPER
in kernel (namely in kernel/bpf/disasm.c) are kept exactly the same both
as demonstration that backwards compat works, but also to avoid
unnecessary code churn.
Note that new ___BPF_FUNC_MAPPER() doesn't forcefully insert comma
between values, as that might not be appropriate in all possible cases
where ___BPF_FUNC_MAPPER might be used by users. This doesn't reduce
usability, as it's trivial to insert that comma inside "callback" macro.
To validate all the manually specified IDs are exactly right, we used
BTF to compare before and after values:
$ bpftool btf dump file ~/linux-build/default/vmlinux | rg bpf_func_id -A 211 > after.txt
$ git stash # stach UAPI changes
$ make -j90
... re-building kernel without UAPI changes ...
$ bpftool btf dump file ~/linux-build/default/vmlinux | rg bpf_func_id -A 211 > before.txt
$ diff -u before.txt after.txt
--- before.txt 2022-10-05 10:48:18.119195916 -0700
+++ after.txt 2022-10-05 10:46:49.446615025 -0700
@@ -1,4 +1,4 @@

'BPF_FUNC_unspec' val=0
'BPF_FUNC_map_lookup_elem' val=1
'BPF_FUNC_map_update_elem' val=2
As can be seen from diff above, the only thing that changed was resulting BTF
type ID of ENUM bpf_func_id, not any of the enumerators, their names or integer
values.
The only other place that needed fixing was scripts/bpf_doc.py used to generate
man pages and bpf_helper_defs.h header for libbpf and selftests. That script is
tightly-coupled to exact shape of ___BPF_FUNC_MAPPER macro definition, so had
to be trivially adapted.

Networking changes for 6.1.
Core
----
- Introduce and use a single page frag cache for allocating small skb
heads, clawing back the 10-20% performance regression in UDP flood
test from previous fixes.
- Run packets which already went thru HW coalescing thru SW GRO.
This significantly improves TCP segment coalescing and simplifies
deployments as different workloads benefit from HW or SW GRO.
- Shrink the size of the base zero-copy send structure.
- Move TCP init under a new slow / sleepable version of DO_ONCE().
BPF
---
- Add BPF-specific, any-context-safe memory allocator.
- Add helpers/kfuncs for PKCS#7 signature verification from BPF
programs.
- Define a new map type and related helpers for user space -> kernel
communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).
- Allow targeting BPF iterators to loop through resources of one
task/thread.
- Add ability to call selected destructive functions.
Expose crash_kexec() to allow BPF to trigger a kernel dump.
Use CAP_SYS_BOOT check on the loading process to judge permissions.
- Enable BPF to collect custom hierarchical cgroup stats efficiently
by integrating with the rstat framework.
- Support struct arguments for trampoline based programs.
Only structs with size <= 16B and x86 are supported.
- Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
sockets (instead of just TCP and UDP sockets).
- Add a helper for accessing CLOCK_TAI for time sensitive network
related programs.
- Support accessing network tunnel metadata's flags.
- Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.
- Add support for writing to Netfilter's nf_conn:mark.
Protocols
---------
- WiFi: more Extremely High Throughput (EHT) and Multi-Link
Operation (MLO) work (802.11be, WiFi 7).
- vsock: improve support for SO_RCVLOWAT.
- SMC: support SO_REUSEPORT.
- Netlink: define and document how to use netlink in a "modern" way.
Support reporting missing attributes via extended ACK.
- IPSec: support collect metadata mode for xfrm interfaces.
- TCPv6: send consistent autoflowlabel in SYN_RECV state
and RST packets.
- TCP: introduce optional per-netns connection hash table to allow
better isolation between namespaces (opt-in, at the cost of memory
and cache pressure).
- MPTCP: support TCP_FASTOPEN_CONNECT.
- Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.
- Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.
- Open vSwitch:
- Allow specifying ifindex of new interfaces.
- Allow conntrack and metering in non-initial user namespace.
- TLS: support the Korean ARIA-GCM crypto algorithm.
- Remove DECnet support.
Driver API
----------
- Allow selecting the conduit interface used by each port
in DSA switches, at runtime.
- Ethernet Power Sourcing Equipment and Power Device support.
- Add tc-taprio support for queueMaxSDU parameter, i.e. setting
per traffic class max frame size for time-based packet schedules.
- Support PHY rate matching - adapting between differing host-side
and link-side speeds.
- Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.
- Validate OF (device tree) nodes for DSA shared ports; make
phylink-related properties mandatory on DSA and CPU ports.
Enforcing more uniformity should allow transitioning to phylink.
- Require that flash component name used during update matches one
of the components for which version is reported by info_get().
- Remove "weight" argument from driver-facing NAPI API as much
as possible. It's one of those magic knobs which seemed like
a good idea at the time but is too indirect to use in practice.
- Support offload of TLS connections with 256 bit keys.

STATX_DIOALIGN for 6.1
Make statx() support reporting direct I/O (DIO) alignment information. This provides a generic interface for userspace programs to determine whether a file supports DIO, and if so with what alignment restrictions. Specifically, STATX_DIOALIGN works on block devices, and on regular files when their containing filesystem has implemented support. An interface like this has been requested for years, since the conditions for when DIO is supported in Linux have gotten increasingly complex over time. Today, DIO support and alignment requirements can be affected by various filesystem features such as multi-device support, data journalling, inline data, encryption, verity, compression, checkpoint disabling, log-structured mode, etc. Further complicating things, Linux v6.0 relaxed the traditional rule of DIO needing to be aligned to the block device's logical block size; now user buffers (but not file offsets) only need to be aligned to the DMA alignment. The approach of uplifting the XFS specific ioctl XFS_IOC_DIOINFO was discarded in favor of creating a clean new interface with statx().

ethtool: add interface to interact with Ethernet Power Equipment
Add interface to support Power Sourcing Equipment. At current step it provides generic way to address all variants of PSE devices as defined in IEEE 802.3-2018 but support only objects specified for IEEE 802.3-2018 104.4 PoDL Power Sourcing Equipment (PSE). Currently supported and mandatory objects are: IEEE 802.3-2018 30.15.1.1.3 aPoDLPSEPowerDetectionStatus IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState IEEE 802.3-2018 30.15.1.2.1 acPoDLPSEAdminControl This is minimal interface needed to control PSE on each separate ethernet port but it provides not all mandatory objects specified in IEEE 802.3-2018. Since "PoDL PSE" and "PSE" have similar names, but some different values I decide to not merge them and keep separate naming schema. This should allow as to be as close to IEEE 802.3 spec as possible and avoid name conflicts in the future. This implementation is connected to PHYs instead of MACs because PSE auto classification can potentially interfere with PHY auto negotiation. So, may be some extra PHY related initialization will be needed. With WIP version of ethtools interaction with PSE capable link looks as following: $ ip l ... 5: t1l1@eth0: <BROADCAST,MULTICAST> .. ... $ ethtool --show-pse t1l1 PSE attributs for t1l1: PoDL PSE Admin State: disabled PoDL PSE Power Detection Status: disabled $ ethtool --set-pse t1l1 podl-pse-admin-control enable $ ethtool --show-pse t1l1 PSE attributs for t1l1: PoDL PSE Admin State: enabled PoDL PSE Power Detection Status: delivering power Signed-off-by: kernel test robot <lkp@intel.com> Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Reviewed-by: Bagas Sanjaya <bagasdotme@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

The Signal polarity component represents the active level of a respective Signal. There are two possible states: positive (rising edge) and negative (falling edge); enum counter_signal_polarity represents these states. A convenience macro COUNTER_COMP_POLARITY() is provided for driver authors to declare a Signal polarity component.

net/sched: taprio: allow user input of per-tc max SDU
IEEE 802.1Q clause 12.29.1.1 "The queueMaxSDUTable structure and data types" and 8.6.8.4 "Enhancements for scheduled traffic" talk about the existence of a per traffic class limitation of maximum frame sizes, with a fallback on the port-based MTU. As far as I am able to understand, the 802.1Q Service Data Unit (SDU) represents the MAC Service Data Unit (MSDU, i.e. L2 payload), excluding any number of prepended VLAN headers which may be otherwise present in the MSDU. Therefore, the queueMaxSDU is directly comparable to the device MTU (1500 means L2 payload sizes are accepted, or frame sizes of 1518 octets, or 1522 plus one VLAN header). Drivers which offload this are directly responsible of translating into other units of measurement. To keep the fast path checks optimized, we keep 2 arrays in the qdisc, one for max_sdu translated into frame length (so that it's comparable to skb->len), and another for offloading and for dumping back to the user.

docs: netlink: clarify the historical baggage of Netlink flags
nlmsg_flags are full of historical baggage, inconsistencies and strangeness. Try to document it more thoroughly. Explain the meaning of the ECHO flag (and while at it clarify the comment in the uAPI). Handwave a little about the NEW request flags and how they make sense on the surface but cater to really old paradigm before commands were a thing. I will add more notes on how to make use of ECHO and discouragement for reuse of flags to the kernel-side documentation.

In order to differenciate between architectures that require no extra synchronisation when accessing the dirty ring and those who do, add a new capability (KVM_CAP_DIRTY_LOG_RING_ACQ_REL) that identify the latter sort. TSO architectures can obviously advertise both, while relaxed architectures must only advertise the ACQ_REL version.

btrfs: separate BLOCK_GROUP_TREE compat RO flag from EXTENT_TREE_V2
The problem of long mount time caused by block group item search is already known for some time, and the solution of block group tree has been proposed. There is really no need to bound this feature into extent tree v2, just introduce compat RO flag, BLOCK_GROUP_TREE, to correctly solve the problem. All the code handling block group root is already in the upstream kernel, thus this patch really only needs to introduce the new compat RO flag. This patch introduces one extra artificial limitation on block group tree feature, that free space cache v2 and no-holes feature must be enabled to use this new compat RO feature. This artificial requirement is mostly to reduce the test combinations, and can be a guideline for future features, to mostly rely on the latest default features.

ublk_drv: add START_USER_RECOVERY and END_USER_RECOVERY support
START_USER_RECOVERY and END_USER_RECOVERY are two new control commands
to support user recovery feature.
After a crash, user should send START_USER_RECOVERY, it will:
(1) check if (a)current ublk_device is UBLK_S_DEV_QUIESCED which was
set by quiesce_work and (b)chardev is released
(2) reinit all ubqs, including:
(a) put the task_struct and reset ->ubq_daemon to NULL.
(b) reset all ublk_io.
(3) reset ub->mm to NULL.
Then, user should start a new process and send FETCH_REQ on each
ubq_daemon.
Finally, user should send END_USER_RECOVERY, it will:
(1) wait for all new ubq_daemons getting ready.
(2) update ublksrv_pid
(3) unquiesce the request queue and expect incoming ublk_queue_rq()
(4) convert ub's state to UBLK_S_DEV_LIVE
Note: we can handle STOP_DEV between START_USER_RECOVERY and
END_USER_RECOVERY. This is helpful to users who cannot start new process
after sending START_USER_RECOVERY ctrl-cmd.

tun: support not enabling carrier in TUNSETIFF
This change adds support for not enabling carrier during TUNSETIFF interface creation by specifying the IFF_NO_CARRIER flag. Our tests make heavy use of tun interfaces. In some scenarios, the test process creates the interface but another process brings it up after the interface is discovered via netlink notification. In that case, it is not possible to create a tun/tap interface with carrier off without it racing against the bring up. Immediately setting carrier off via TUNSETCARRIER is still too late.

net: phy: Add support for rate matching
This adds support for rate matching (also known as rate adaptation) to the phy subsystem. The general idea is that the phy interface runs at one speed, and the MAC throttles the rate at which it sends packets to the link speed. There's a good overview of several techniques for achieving this at [1]. This patch adds support for three: pause-frame based (such as in Aquantia phys), CRS-based (such as in 10PASS-TS and 2BASE-TL), and open-loop-based (such as in 10GBASE-W). This patch makes a few assumptions and a few non assumptions about the types of rate matching available. First, it assumes that different phys may use different forms of rate matching. Second, it assumes that phys can use rate matching for any of their supported link speeds (e.g. if a phy supports 10BASE-T and XGMII, then it can adapt XGMII to 10BASE-T). Third, it does not assume that all interface modes will use the same form of rate matching. Fourth, it does not assume that all phy devices will support rate matching (even if some do). Relaxing or strengthening these (non-)assumptions could result in a different API. For example, if all interface modes were assumed to use the same form of rate matching, then a bitmask of interface modes supportting rate matching would suffice. For some better visibility into the process, the current rate matching mode is exposed as part of the ethtool ksettings. For the moment, only read access is supported. I'm not sure what userspace might want to configure yet (disable it altogether, disable just one mode, specify the mode to use, etc.). For the moment, since only pause-based rate adaptation support is added in the next few commits, rate matching can be disabled altogether by adjusting the advertisement. 802.3 calls this feature "rate adaptation" in clause 49 (10GBASE-R) and "rate matching" in clause 61 (10PASS-TL and 2BASE-TS). Aquantia also calls this feature "rate adaptation". I chose "rate matching" because it is shorter, and because Russell doesn't think "adaptation" is correct in this context.

bpf: Add bpf_user_ringbuf_drain() helper
In a prior change, we added a new BPF_MAP_TYPE_USER_RINGBUF map type which
will allow user-space applications to publish messages to a ring buffer
that is consumed by a BPF program in kernel-space. In order for this
map-type to be useful, it will require a BPF helper function that BPF
programs can invoke to drain samples from the ring buffer, and invoke
callbacks on those samples. This change adds that capability via a new BPF
helper function:
bpf_user_ringbuf_drain(struct bpf_map *map, void *callback_fn, void *ctx,
u64 flags)
BPF programs may invoke this function to run callback_fn() on a series of
samples in the ring buffer. callback_fn() has the following signature:
long callback_fn(struct bpf_dynptr *dynptr, void *context);
Samples are provided to the callback in the form of struct bpf_dynptr *'s,
which the program can read using BPF helper functions for querying
struct bpf_dynptr's.
In order to support bpf_ringbuf_drain(), a new PTR_TO_DYNPTR register
type is added to the verifier to reflect a dynptr that was allocated by
a helper function and passed to a BPF program. Unlike PTR_TO_STACK
dynptrs which are allocated on the stack by a BPF program, PTR_TO_DYNPTR
dynptrs need not use reference tracking, as the BPF helper is trusted to
properly free the dynptr before returning. The verifier currently only
supports PTR_TO_DYNPTR registers that are also DYNPTR_TYPE_LOCAL.
Note that while the corresponding user-space libbpf logic will be added
in a subsequent patch, this patch does contain an implementation of the
.map_poll() callback for BPF_MAP_TYPE_USER_RINGBUF maps. This
.map_poll() callback guarantees that an epoll-waiting user-space
producer will receive at least one event notification whenever at least
one sample is drained in an invocation of bpf_user_ringbuf_drain(),
provided that the function is not invoked with the BPF_RB_NO_WAKEUP
flag. If the BPF_RB_FORCE_WAKEUP flag is provided, a wakeup
notification is sent even if no sample was drained.

bpf: Define new BPF_MAP_TYPE_USER_RINGBUF map type
We want to support a ringbuf map type where samples are published from user-space, to be consumed by BPF programs. BPF currently supports a kernel -> user-space circular ring buffer via the BPF_MAP_TYPE_RINGBUF map type. We'll need to define a new map type for user-space -> kernel, as none of the helpers exported for BPF_MAP_TYPE_RINGBUF will apply to a user-space producer ring buffer, and we'll want to add one or more helper functions that would not apply for a kernel-producer ring buffer. This patch therefore adds a new BPF_MAP_TYPE_USER_RINGBUF map type definition. The map type is useless in its current form, as there is no way to access or use it for anything until we one or more BPF helpers. A follow-on patch will therefore add a new helper function that allows BPF programs to run callbacks on samples that are published to the ring buffer.

bpf, cgroup: Reject prog_attach_flags array when effective query
Attach flags is only valid for attached progs of this layer cgroup,
but not for effective progs. For querying with EFFECTIVE flags,
exporting attach flags does not make sense. So when effective query,
we reject prog_attach_flags array and don't need to populate it.
Also we limit attach_flags to output 0 during effective query.

iio: add modifiers for linear acceleration
Add IIO_MOD_LINEAR_X, IIO_MOD_LINEAR_Y and IIO_MOD_LINEAR_Z modifiers to te IIO core, which is preparatory for adding the Bosch BNO055 IMU driver. Bosch BNO055 IMU can report raw accelerations (among x, y and z axis) as well as the so called "linear accelerations" (again, among x, y and z axis) which is basically the acceleration after subtracting gravity and for which those new modifiers are for.

io_uring: add IORING_SETUP_DEFER_TASKRUN
Allow deferring async tasks until the user calls io_uring_enter(2) with the IORING_ENTER_GETEVENTS flag. Enable this mode with a flag at io_uring_setup time. This functionality requires that the later io_uring_enter will be called from the same submission task, and therefore restrict this flag to work only when IORING_SETUP_SINGLE_ISSUER is also set. Being able to hand pick when tasks are run prevents the problem where there is current work to be done, however task work runs anyway. For example, a common workload would obtain a batch of CQEs, and process each one. Interrupting this to additional taskwork would add latency but not gain anything. If instead task work is deferred to just before more CQEs are obtained then no additional latency is added. The way this is implemented is by trying to keep task work local to a io_ring_ctx, rather than to the submission task. This is required, as the application will want to wake up only a single io_ring_ctx at a time to process work, and so the lists of work have to be kept separate. This has some other benefits like not having to check the task continually in handle_tw_list (and potentially unlocking/locking those), and reducing locks in the submit & process completions path. There are networking cases where using this option can reduce request latency by 50%. For example a contrived example using [1] where the client sends 2k data and receives the same data back while doing some system calls (to trigger task work) shows this reduction. The reason ends up being that if sending responses is delayed by processing task work, then the client side sits idle. Whereas reordering the sends first means that the client runs it's workload in parallel with the local task work. [1]: Using https://github.com/DylanZA/netbench/tree/defer_run Client: ./netbench --client_only 1 --control_port 10000 --host <host> --tx "epoll --threads 16 --per_thread 1 --size 2048 --resp 2048 --workload 1000" Server: ./netbench --server_only 1 --control_port 10000 --rx "io_uring --defer_taskrun 0 --workload 100" --rx "io_uring --defer_taskrun 1 --workload 100" Signed-off-by: Dylan Yudaken <dylany@fb.com> Link: https://lore.kernel.org/r/20220830125013.570060-5-dylany@fb.com Signed-off-by: Jens Axboe <axboe@kernel.dk> |

seg6: add NEXT-C-SID support for SRv6 End behavior
The NEXT-C-SID mechanism described in [1] offers the possibility of
encoding several SRv6 segments within a single 128 bit SID address. Such
a SID address is called a Compressed SID (C-SID) container. In this way,
the length of the SID List can be drastically reduced.
A SID instantiated with the NEXT-C-SID flavor considers an IPv6 address
logically structured in three main blocks: i) Locator-Block; ii)
Locator-Node Function; iii) Argument.
C-SID container
+------------------------------------------------------------------+
| Locator-Block |Loc-Node| Argument |
| |Function| |
+------------------------------------------------------------------+
<--------- B -----------> <- NF -> <------------- A --------------->
(i) The Locator-Block can be any IPv6 prefix available to the provider;
(ii) The Locator-Node Function represents the node and the function to
be triggered when a packet is received on the node;
(iii) The Argument carries the remaining C-SIDs in the current C-SID
container.
The NEXT-C-SID mechanism relies on the "flavors" framework defined in
[2]. The flavors represent additional operations that can modify or
extend a subset of the existing behaviors.
This patch introduces the support for flavors in SRv6 End behavior
implementing the NEXT-C-SID one. An SRv6 End behavior with NEXT-C-SID
flavor works as an End behavior but it is capable of processing the
compressed SID List encoded in C-SID containers.
An SRv6 End behavior with NEXT-C-SID flavor can be configured to support
user-provided Locator-Block and Locator-Node Function lengths. In this
implementation, such lengths must be evenly divisible by 8 (i.e. must be
byte-aligned), otherwise the kernel informs the user about invalid
values with a meaningful error code and message through netlink_ext_ack.
If Locator-Block and/or Locator-Node Function lengths are not provided
by the user during configuration of an SRv6 End behavior instance with
NEXT-C-SID flavor, the kernel will choose their default values i.e.,
32-bit Locator-Block and 16-bit Locator-Node Function.

net: dsa: allow the DSA master to be seen and changed through rtnetlink
Some DSA switches have multiple CPU ports, which can be used to improve CPU termination throughput, but DSA, through dsa_tree_setup_cpu_ports(), sets up only the first one, leading to suboptimal use of hardware. The desire is to not change the default configuration but to permit the user to create a dynamic mapping between individual user ports and the CPU port that they are served by, configurable through rtnetlink. It is also intended to permit load balancing between CPU ports, and in that case, the foreseen model is for the DSA master to be a bonding interface whose lowers are the physical DSA masters. To that end, we create a struct rtnl_link_ops for DSA user ports with the "dsa" kind. We expose the IFLA_DSA_MASTER link attribute that contains the ifindex of the newly desired DSA master.

can: raw: add CAN XL support
Enable CAN_RAW sockets to read and write CAN XL frames analogue to the CAN FD extension (new CAN_RAW_XL_FRAMES sockopt). A CAN XL network interface is capable to handle Classical CAN, CAN FD and CAN XL frames. When CAN_RAW_XL_FRAMES is enabled, the CAN_RAW socket checks whether the addressed CAN network interface is capable to handle the provided CAN frame. In opposite to the fixed number of bytes for - CAN frames (CAN_MTU = sizeof(struct can_frame)) - CAN FD frames (CANFD_MTU = sizeof(struct can_frame)) the number of bytes when reading/writing CAN XL frames depends on the number of data bytes. For efficiency reasons the length of the struct canxl_frame is truncated to the needed size for read/write operations. This leads to a calculated size of CANXL_HDR_SIZE + canxl_frame::len which is enforced on write() operations and guaranteed on read() operations. NB: Valid length values are 1 .. 2048 (CANXL_MIN_DLEN .. CANXL_MAX_DLEN).

can: canxl: update CAN infrastructure for CAN XL frames
- add new ETH_P_CANXL ethernet protocol type - update skb checks for CAN XL - add alloc_canxl_skb() which now needs a data length parameter - introduce init_can_skb_reserve() to reduce code duplication Acked-by: Vincent Mailhol <mailhol.vincent@wanadoo.fr> Signed-off-by: Oliver Hartkopp <socketcan@hartkopp.net> Link: https://lore.kernel.org/all/20220912170725.120748-6-socketcan@hartkopp.net Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> |

can: canxl: introduce CAN XL data structure
This patch adds defines for data structures and length information for CAN XL (CAN with eXtended data Length) which can transfer up to 2048 byte inside a single frame. Notable changes from CAN FD: - the 11 bit arbitration field is now named 'priority' instead of 'can_id' (there are no 29 bit identifiers nor RTR frames anymore) - the data length needs a uint16 value to cover up to 2048 byte (the length element position is different to struct can[fd]_frame) - new fields (SDT, AF) and a SEC bit have been introduced - the virtual CAN interface identifier is not part if the CAN XL frame struct as this VCID value is stored in struct skbuff (analog to vlan id) Acked-by: Vincent Mailhol <mailhol.vincent@wanadoo.fr> Signed-off-by: Oliver Hartkopp <socketcan@hartkopp.net> Link: https://lore.kernel.org/all/20220912170725.120748-5-socketcan@hartkopp.net Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> |

can: set CANFD_FDF flag in all CAN FD frame structures
To simplify the testing in user space all struct canfd_frame's provided by the CAN subsystem of the Linux kernel now have the CANFD_FDF flag set in canfd_frame::flags. NB: Handcrafted ETH_P_CANFD frames introduced via PF_PACKET socket might not set this bit correctly. During the check for sufficient headroom in PF_PACKET sk_buffs the uninitialized CAN sk_buff data structures are filled. In the case of a CAN FD frame the CANFD_FDF flag is set accordingly. As the CAN frame content is already zero initialized in alloc_canfd_skb() the obsolete initialization of cf->flags in the CTU CAN FD driver has been removed as it would overwrite the already set CANFD_FDF flag.

userfaultfd: add /dev/userfaultfd for fine grained access control
Historically, it has been shown that intercepting kernel faults with
userfaultfd (thereby forcing the kernel to wait for an arbitrary amount of
time) can be exploited, or at least can make some kinds of exploits
easier. So, in

statx: add direct I/O alignment information
Traditionally, the conditions for when DIO (direct I/O) is supported
were fairly simple. For both block devices and regular files, DIO had
to be aligned to the logical block size of the block device.
However, due to filesystem features that have been added over time (e.g.
multi-device support, data journalling, inline data, encryption, verity,
compression, checkpoint disabling, log-structured mode), the conditions
for when DIO is allowed on a regular file have gotten increasingly
complex. Whether a particular regular file supports DIO, and with what
alignment, can depend on various file attributes and filesystem mount
options, as well as which block device(s) the file's data is located on.
Moreover, the general rule of DIO needing to be aligned to the block
device's logical block size was recently relaxed to allow user buffers
(but not file offsets) aligned to the DMA alignment instead. See

Florian Westphal says: ==================== The following set contains changes for your *net-next* tree: - make conntrack ignore packets that are delayed (containing data already acked). The current behaviour to flag them as INVALID causes more harm than good, let them pass so peer can send an immediate ACK for the most recent sequence number. - make conntrack recognize when both peers have sent 'invalid' FINs: This helps cleaning out stale connections faster for those cases where conntrack is no longer in sync with the actual connection state. - Now that DECNET is gone, we don't need to reserve space for DECNET related information. - compact common 'find a free port number for the new inbound connection' code and move it to a helper, then cap number of tries the new helper will make until it gives up. - replace various instances of strlcpy with strscpy, from Wolfram Sang. ==================== Signed-off-by: David S.

vfio: Introduce DMA logging uAPIs
DMA logging allows a device to internally record what DMAs the device is initiating and report them back to userspace. It is part of the VFIO migration infrastructure that allows implementing dirty page tracking during the pre copy phase of live migration. Only DMA WRITEs are logged, and this API is not connected to VFIO_DEVICE_FEATURE_MIG_DEVICE_STATE. This patch introduces the DMA logging involved uAPIs. It uses the FEATURE ioctl with its GET/SET/PROBE options as of below. It exposes a PROBE option to detect if the device supports DMA logging. It exposes a SET option to start device DMA logging in given IOVAs ranges. It exposes a SET option to stop device DMA logging that was previously started. It exposes a GET option to read back and clear the device DMA log. Extra details exist as part of vfio.h per a specific option.
