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

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(). For more information, see the individual commits and the man page update https://lore.kernel.org/r/20220722074229.148925-1-ebiggers@kernel.org. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCYzpV2xQcZWJpZ2dlcnNA Z29vZ2xlLmNvbQAKCRDzXCl4vpKOKwF1AQDetPX5hyuq0/mwikOywLTTJsoHgGY5 euO+dISqjH/InwD9HAQqfPRkdM1j4ml82BjjkAfrhzZXOOWPKJm0zOhMIQg= =0Oav -----END PGP SIGNATURE----- Merge tag 'statx-dioalign-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux Pull STATX_DIOALIGN support from Eric Biggers: "Make statx() support reporting direct I/O (DIO) alignment information.

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> |

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.

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.

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(),

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.

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: 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.

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

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.
