iommufd: Remove IOMMUFD_PAGE_RESP_FAILURE
The response code of IOMMUFD_PAGE_RESP_FAILURE was defined to be
equivalent to the "Response Failure" in PCI spec, section 10.4.2.1.
This response code indicates that one or more pages within the
associated request group have encountered or caused an unrecoverable
error. Therefore, this response disables the PRI at the function.
Modern I/O virtualization technologies, like SR-IOV, share PRI among
the assignable device units. Therefore, a response failure on one unit
might cause I/O failure on other units.
Remove this response code so that user space can only respond with
SUCCESS or INVALID. The VMM is recommended to emulate a failure response
as a PRI reset, or PRI disable and changing to a non-PRI domain.

btrfs: remove raid-stripe-tree encoding field from stripe_extent
Remove the encoding field from 'struct btrfs_stripe_extent'. It was originally intended to encode the RAID type as well as if we're a data or a parity stripe. But the RAID type can be inferred form the block-group and the data vs. parity differentiation can be done easier with adding a new key type for parity stripes in the RAID stripe tree.

btrfs: uapi: record temporary super flags used by btrfstune
[BUG] There is a bug report that a canceled checksum conversion (still experimental feature) results in unexpected super block flags: csum_type 0 (crc32c) csum_size 4 csum 0x14973811 [match] bytenr 65536 flags 0x1000000001 ( WRITTEN | CHANGING_FSID_V2 ) magic _BHRfS_M [match] While for a filesystem with ongoing checksum conversion it should have either CHANGING_DATA_CSUM or CHANGING_META_CSUM. [CAUSE] It turns out that, due to btrfs-progs keeps its own extra flags inside its own ctree.h headers, not the shared uapi headers, we have conflicting super flags: kernel-shared/uapi/btrfs_tree.h:#define BTRFS_SUPER_FLAG_METADUMP_V2 (1ULL << 34) kernel-shared/uapi/btrfs_tree.h:#define BTRFS_SUPER_FLAG_CHANGING_FSID (1ULL << 35) kernel-shared/uapi/btrfs_tree.h:#define BTRFS_SUPER_FLAG_CHANGING_FSID_V2 (1ULL << 36) kernel-shared/ctree.h:#define BTRFS_SUPER_FLAG_CHANGING_DATA_CSUM (1ULL << 36) kernel-shared/ctree.h:#define BTRFS_SUPER_FLAG_CHANGING_META_CSUM (1ULL << 37) Note that CHANGING_FSID_V2 is conflicting with CHANGING_DATA_CSUM. [FIX] The proper fix would be done inside btrfs-progs, but to keep everything properly recorded, we should have everything inside the same uapi header. Copy all the new flags into uapi header, and change the value for CHANGING_DATA_CSUM and CHANGING_META_CSUM, while keep the value of CHANGING_BG_TREE untouched. Thankfully checksum change is still only experimental and all those CHANGING_* flags are transient (only for btrfs-progs to resume the conversion, and kernel will reject them all), the damage is still minor.

Merge branch 'iommufd_pri' into iommufd for-next
Lu Baolu says: ==================== This series implements the functionality of delivering IO page faults to user space through the IOMMUFD framework. One feasible use case is the nested translation. Nested translation is a hardware feature that supports two-stage translation tables for IOMMU. The second-stage translation table is managed by the host VMM, while the first-stage translation table is owned by user space. This allows user space to control the IOMMU mappings for its devices. When an IO page fault occurs on the first-stage translation table, the IOMMU hardware can deliver the page fault to user space through the IOMMUFD framework. User space can then handle the page fault and respond to the device top-down through the IOMMUFD. This allows user space to implement its own IO page fault handling policies. User space application that is capable of handling IO page faults should allocate a fault object, and bind the fault object to any domain that it is willing to handle the fault generatd for them. On a successful return of fault object allocation, the user can retrieve and respond to page faults by reading or writing to the file descriptor (FD) returned. The iommu selftest framework has been updated to test the IO page fault delivery and response functionality. ==================== * iommufd_pri: iommufd/selftest: Add coverage for IOPF test iommufd/selftest: Add IOPF support for mock device iommufd: Associate fault object with iommufd_hw_pgtable iommufd: Fault-capable hwpt attach/detach/replace iommufd: Add iommufd fault object iommufd: Add fault and response message definitions iommu: Extend domain attach group with handle support iommu: Add attach handle to struct iopf_group iommu: Remove sva handle list iommu: Introduce domain attachment handle Link: https://lore.kernel.org/all/20240702063444.105814-1-baolu.lu@linux.intel.com Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> |

iommufd: Associate fault object with iommufd_hw_pgtable
When allocating a user iommufd_hw_pagetable, the user space is allowed to associate a fault object with the hw_pagetable by specifying the fault object ID in the page table allocation data and setting the IOMMU_HWPT_FAULT_ID_VALID flag bit. On a successful return of hwpt allocation, the user can retrieve and respond to page faults by reading and writing the file interface of the fault object. Once a fault object has been associated with a hwpt, the hwpt is iopf-capable, indicated by hwpt->fault is non NULL. Attaching, detaching, or replacing an iopf-capable hwpt to an RID or PASID will differ from those that are not iopf-capable.

iommufd: Add iommufd fault object
An iommufd fault object provides an interface for delivering I/O page faults to user space. These objects are created and destroyed by user space, and they can be associated with or dissociated from hardware page table objects during page table allocation or destruction. User space interacts with the fault object through a file interface. This interface offers a straightforward and efficient way for user space to handle page faults. It allows user space to read fault messages sequentially and respond to them by writing to the same file. The file interface supports reading messages in poll mode, so it's recommended that user space applications use io_uring to enhance read and write efficiency. A fault object can be associated with any iopf-capable iommufd_hw_pgtable during the pgtable's allocation. All I/O page faults triggered by devices when accessing the I/O addresses of an iommufd_hw_pgtable are routed through the fault object to user space. Similarly, user space's responses to these page faults are routed back to the iommu device driver through the same fault object.

iommufd: Add fault and response message definitions
iommu_hwpt_pgfaults represent fault messages that the userspace can retrieve. Multiple iommu_hwpt_pgfaults might be put in an iopf group, with the IOMMU_PGFAULT_FLAGS_LAST_PAGE flag set only for the last iommu_hwpt_pgfault. An iommu_hwpt_page_response is a response message that the userspace should send to the kernel after finishing handling a group of fault messages. The @dev_id, @pasid, and @grpid fields in the message identify an outstanding iopf group for a device. The @cookie field, which matches the cookie field of the last fault in the group, will be used by the kernel to look up the pending message.

wifi: cfg80211: add support for advertising multiple radios belonging to a wiphy
The prerequisite for MLO support in cfg80211/mac80211 is that all the links participating in MLO must be from the same wiphy/ieee80211_hw. To meet this expectation, some drivers may need to group multiple discrete hardware each acting as a link in MLO under single wiphy. With this change, supported frequencies and interface combinations of each individual radio are reported to user space. This allows user space to figure out the limitations of what combination of channels can be used concurrently. Even for non-MLO devices, this improves support for devices capable of running on multiple channels at the same time.

The maximum length of the user-defined cookie is set to 16, same as tc_cookie, to discourage using cookies that will not be offloadable.

net: psample: allow using rate as probability
Although not explicitly documented in the psample module itself, the definition of PSAMPLE_ATTR_SAMPLE_RATE seems inherited from act_sample. Quoting tc-sample(8): "RATE of 100 will lead to an average of one sampled packet out of every 100 observed." With this semantics, the rates that we can express with an unsigned 32-bits number are very unevenly distributed and concentrated towards "sampling few packets". For example, we can express a probability of 2.32E-8% but we cannot express anything between 100% and 50%. For sampling applications that are capable of sampling a decent amount of packets, this sampling rate semantics is not very useful. Add a new flag to the uAPI that indicates that the sampling rate is expressed in scaled probability, this is: - 0 is 0% probability, no packets get sampled. - U32_MAX is 100% probability, all packets get sampled.

perf/x86/intel: Support new data source for Lunar Lake
A new PEBS data source format is introduced for the p-core of Lunar Lake. The data source field is extended to 8 bits with new encodings. A new layout is introduced into the union intel_x86_pebs_dse. Introduce the lnl_latency_data() to parse the new format. Enlarge the pebs_data_source[] accordingly to include new encodings. Only the mem load and the mem store events can generate the data source. Introduce INTEL_HYBRID_LDLAT_CONSTRAINT and INTEL_HYBRID_STLAT_CONSTRAINT to mark them. Add two new bits for the new cache-related data src, L2_MHB and MSC. The L2_MHB is short for L2 Miss Handling Buffer, which is similar to LFB (Line Fill Buffer), but to track the L2 Cache misses. The MSC stands for the memory-side cache.

um: add shared memory optimisation for time-travel=ext
With external time travel, a LOT of message can end up being exchanged on the socket, taking a significant amount of time just to do that. Add a new shared memory optimisation to that, where a number of changes are made: - the controller sends a client ID and a shared memory FD (and a logging FD we don't use) in the ACK message to the initial START - the shared memory holds the current time and the free_until value, so that there's no need to exchange messages for that - if the client that's running has shared memory support, any client (the running one included) can request the next time it wants to run inside the shared memory, rather than sending a message, by also updating the free_until value - when shared memory is enabled, RUN/WAIT messages no longer have an ACK, further cutting down on messages Together, this can reduce the number of messages very significantly, and reduce overall test/simulation run time.

um: time-travel: support time-travel protocol broadcast messages
Add a message type to the time-travel protocol to broadcast a small (64-bit) value to all participants in a simulation. The main use case is to have an identical message come to all participants in a simulation, e.g. to separate out logs for different tests running in a single simulation. Down in the guts of time_travel_handle_message() we can't use printk() and not even printk_deferred(), so just store the message and print it at the start of the userspace() function. Unfortunately this means that other prints in the kernel can actually bypass the message, but in most cases where this is used, for example to separate test logs, userspace will be involved. Also, even if we could use printk_deferred(), we'd still need to flush it out in the userspace() function since otherwise userspace messages might cross it. As a result, this is a reasonable compromise, there's no need to have any core changes and it solves the main use case we have for it.

tcp_metrics: add netlink protocol spec in YAML
Add a protocol spec for tcp_metrics, so that it's accessible via YNL.
Useful at the very least for testing fixes.
In this episode of "10,000 ways to complicate netlink" the metric
nest has defines which are off by 1. iproute2 does:
struct rtattr *m[TCP_METRIC_MAX + 1 + 1];
parse_rtattr_nested(m, TCP_METRIC_MAX + 1, a);
for (i = 0; i < TCP_METRIC_MAX + 1; i++) {
// ...
attr = m[i + 1];
This is too weird to support in YNL, add a new set of defines
with _correct_ values to the official kernel header.

iio: core: Add new DMABUF interface infrastructure
Add the necessary infrastructure to the IIO core to support a new optional DMABUF based interface. With this new interface, DMABUF objects (externally created) can be attached to a IIO buffer, and subsequently used for data transfer. A userspace application can then use this interface to share DMABUF objects between several interfaces, allowing it to transfer data in a zero-copy fashion, for instance between IIO and the USB stack. The userspace application can also memory-map the DMABUF objects, and access the sample data directly. The advantage of doing this vs. the read() interface is that it avoids an extra copy of the data between the kernel and userspace. This is particularly userful for high-speed devices which produce several megabytes or even gigabytes of data per second. As part of the interface, 3 new IOCTLs have been added: IIO_BUFFER_DMABUF_ATTACH_IOCTL(int fd): Attach the DMABUF object identified by the given file descriptor to the buffer. IIO_BUFFER_DMABUF_DETACH_IOCTL(int fd): Detach the DMABUF object identified by the given file descriptor from the buffer. Note that closing the IIO buffer's file descriptor will automatically detach all previously attached DMABUF objects. IIO_BUFFER_DMABUF_ENQUEUE_IOCTL(struct iio_dmabuf *): Request a data transfer to/from the given DMABUF object. Its file descriptor, as well as the transfer size and flags are provided in the "iio_dmabuf" structure. These three IOCTLs have to be performed on the IIO buffer's file descriptor, obtained using the IIO_BUFFER_GET_FD_IOCTL() ioctl.

Add a pair of new ethtool messages that allow: * User space to trigger firmware update of transceiver modules * The kernel to notify user space about the progress of the process The user interface is designed to be asynchronous in order to avoid RTNL being held for too long and to allow several modules to be updated simultaneously.

xfrm: support sending NAT keepalives in ESP in UDP states
Add the ability to send out RFC-3948 NAT keepalives from the xfrm stack. To use, Userspace sets an XFRM_NAT_KEEPALIVE_INTERVAL integer property when creating XFRM outbound states which denotes the number of seconds between keepalive messages. Keepalive messages are sent from a per net delayed work which iterates over the xfrm states. The logic is guarded by the xfrm state spinlock due to the xfrm state walk iterator. Possible future enhancements: - Adding counters to keep track of sent keepalives. - deduplicate NAT keepalives between states sharing the same nat keepalive parameters. - provisioning hardware offloads for devices capable of implementing this. - revise xfrm state list to use an rcu list in order to avoid running this under spinlock.

ethtool: provide customized dim profile management
The NetDIM library, currently leveraged by an array of NICs, delivers
excellent acceleration benefits. Nevertheless, NICs vary significantly
in their dim profile list prerequisites.
Specifically, virtio-net backends may present diverse sw or hw device
implementation, making a one-size-fits-all parameter list impractical.
On Alibaba Cloud, the virtio DPU's performance under the default DIM
profile falls short of expectations, partly due to a mismatch in
parameter configuration.
I also noticed that ice/idpf/ena and other NICs have customized
profilelist or placed some restrictions on dim capabilities.
Motivated by this, I tried adding new params for "ethtool -C" that provides
a per-device control to modify and access a device's interrupt parameters.
Usage
========
The target NIC is named ethx.
Assume that ethx only declares support for rx profile setting
(with DIM_PROFILE_RX flag set in profile_flags) and supports modification
of usec and pkt fields.
1. Query the currently customized list of the device
$ ethtool -c ethx
...
rx-profile:
{.usec = 1, .pkts = 256, .comps = n/a,},
{.usec = 8, .pkts = 256, .comps = n/a,},
{.usec = 64, .pkts = 256, .comps = n/a,},
{.usec = 128, .pkts = 256, .comps = n/a,},
{.usec = 256, .pkts = 256, .comps = n/a,}
tx-profile: n/a
2. Tune
$ ethtool -C ethx rx-profile 1,1,n_2,n,n_3,3,n_4,4,n_n,5,n
"n" means do not modify this field.
$ ethtool -c ethx
...
rx-profile:
{.usec = 1, .pkts = 1, .comps = n/a,},
{.usec = 2, .pkts = 256, .comps = n/a,},
{.usec = 3, .pkts = 3, .comps = n/a,},
{.usec = 4, .pkts = 4, .comps = n/a,},
{.usec = 256, .pkts = 5, .comps = n/a,}
tx-profile: n/a
3. Hint
If the device does not support some type of customized dim profiles,
the corresponding "n/a" will display.
If the "n/a" field is being modified, -EOPNOTSUPP will be reported.

nsfs: add pid translation ioctls
Add ioctl()s to translate pids between pid namespaces. LXCFS is a tiny fuse filesystem used to virtualize various aspects of procfs. LXCFS is run on the host. The files and directories it creates can be bind-mounted by e.g. a container at startup and mounted over the various procfs files the container wishes to have virtualized. When e.g. a read request for uptime is received, LXCFS will receive the pid of the reader. In order to virtualize the corresponding read, LXCFS needs to know the pid of the init process of the reader's pid namespace. In order to do this, LXCFS first needs to fork() two helper processes. The first helper process setns() to the readers pid namespace. The second helper process is needed to create a process that is a proper member of the pid namespace. The second helper process then creates a ucred message with ucred.pid set to 1 and sends it back to LXCFS. The kernel will translate the ucred.pid field to the corresponding pid number in LXCFS's pid namespace. This way LXCFS can learn the init pid number of the reader's pid namespace and can go on to virtualize. Since these two forks() are costly LXCFS maintains an init pid cache that caches a given pid for a fixed amount of time. The cache is pruned during new read requests. However, even with the cache the hit of the two forks() is singificant when a very large number of containers are running. With this simple patch we add an ns ioctl that let's a caller retrieve the init pid nr of a pid namespace through its pid namespace fd. This significantly improves performance with a very simple change. Support translation of pids and tgids. Other concepts can be added but there are no obvious users for this right now. To protect against races pidfds can be used to check whether the process is still valid. If needed, this can also be extended to work on pidfds directly.

fs: Initial atomic write support
An atomic write is a write issued with torn-write protection, meaning that for a power failure or any other hardware failure, all or none of the data from the write will be stored, but never a mix of old and new data. Userspace may add flag RWF_ATOMIC to pwritev2() to indicate that the write is to be issued with torn-write prevention, according to special alignment and length rules. For any syscall interface utilizing struct iocb, add IOCB_ATOMIC for iocb->ki_flags field to indicate the same. A call to statx will give the relevant atomic write info for a file: - atomic_write_unit_min - atomic_write_unit_max - atomic_write_segments_max Both min and max values must be a power-of-2. Applications can avail of atomic write feature by ensuring that the total length of a write is a power-of-2 in size and also sized between atomic_write_unit_min and atomic_write_unit_max, inclusive. Applications must ensure that the write is at a naturally-aligned offset in the file wrt the total write length. The value in atomic_write_segments_max indicates the upper limit for IOV_ITER iovcnt. Add file mode flag FMODE_CAN_ATOMIC_WRITE, so files which do not have the flag set will have RWF_ATOMIC rejected and not just ignored. Add a type argument to kiocb_set_rw_flags() to allows reads which have RWF_ATOMIC set to be rejected. Helper function generic_atomic_write_valid() can be used by FSes to verify compliant writes. There we check for iov_iter type is for ubuf, which implies iovcnt==1 for pwritev2(), which is an initial restriction for atomic_write_segments_max. Initially the only user will be bdev file operations write handler. We will rely on the block BIO submission path to ensure write sizes are compliant for the bdev, so we don't need to check atomic writes sizes yet.

KVM: Ensure new code that references immediate_exit gets extra scrutiny
Ensure that any new KVM code that references immediate_exit gets extra scrutiny by renaming it to immediate_exit__unsafe in kernel code. All fields in struct kvm_run are subject to TOCTOU races since they are mapped into userspace, which may be malicious or buggy. To protect KVM, introduces a new macro that appends __unsafe to select field names in struct kvm_run, hinting to developers and reviewers that accessing such fields must be done carefully. Apply the new macro to immediate_exit, since userspace can make immediate_exit inconsistent with vcpu->wants_to_run, i.e. accessing immediate_exit directly could lead to unexpected bugs in the future.

net/smc: Introduce IPPROTO_SMC
This patch allows to create smc socket via AF_INET, similar to the following code, /* create v4 smc sock */ v4 = socket(AF_INET, SOCK_STREAM, IPPROTO_SMC); /* create v6 smc sock */ v6 = socket(AF_INET6, SOCK_STREAM, IPPROTO_SMC); There are several reasons why we believe it is appropriate here: 1. For smc sockets, it actually use IPv4 (AF-INET) or IPv6 (AF-INET6) address. There is no AF_SMC address at all. 2. Create smc socket in the AF_INET(6) path, which allows us to reuse the infrastructure of AF_INET(6) path, such as common ebpf hooks. Otherwise, smc have to implement it again in AF_SMC path.

KVM: x86: Add KVM_RUN_X86_GUEST_MODE kvm_run flag
When a vCPU is interrupted by a signal while running a nested guest, KVM will exit to userspace with L2 state. However, userspace has no way to know whether it sees L1 or L2 state (besides calling KVM_GET_STATS_FD, which does not have a stable ABI). This causes multiple problems: The simplest one is L2 state corruption when userspace marks the sregs as dirty. See this mailing list thread [1] for a complete discussion. Another problem is that if userspace decides to continue by emulating instructions, it will unknowingly emulate with L2 state as if L1 doesn't exist, which can be considered a weird guest escape. Introduce a new flag, KVM_RUN_X86_GUEST_MODE, in the kvm_run data structure, which is set when the vCPU exited while running a nested guest. Also introduce a new capability, KVM_CAP_X86_GUEST_MODE, to advertise the functionality to userspace.

KVM: x86: Add a capability to configure bus frequency for APIC timer
Add KVM_CAP_X86_APIC_BUS_CYCLES_NS capability to configure the APIC
bus clock frequency for APIC timer emulation.
Allow KVM_ENABLE_CAPABILITY(KVM_CAP_X86_APIC_BUS_CYCLES_NS) to set the
frequency in nanoseconds. When using this capability, the user space
VMM should configure CPUID leaf 0x15 to advertise the frequency.
Vishal reported that the TDX guest kernel expects a 25MHz APIC bus
frequency but ends up getting interrupts at a significantly higher rate.
The TDX architecture hard-codes the core crystal clock frequency to
25MHz and mandates exposing it via CPUID leaf 0x15. The TDX architecture
does not allow the VMM to override the value.
In addition, per Intel SDM:
"The APIC timer frequency will be the processor’s bus clock or core
crystal clock frequency (when TSC/core crystal clock ratio is
enumerated in CPUID leaf 0x15) divided by the value specified in
the divide configuration register."
The resulting 25MHz APIC bus frequency conflicts with the KVM hardcoded
APIC bus frequency of 1GHz.
The KVM doesn't enumerate CPUID leaf 0x15 to the guest unless the user
space VMM sets it using KVM_SET_CPUID. If the CPUID leaf 0x15 is
enumerated, the guest kernel uses it as the APIC bus frequency. If not,
the guest kernel measures the frequency based on other known timers like
the ACPI timer or the legacy PIT. As reported by Vishal the TDX guest
kernel expects a 25MHz timer frequency but gets timer interrupt more
frequently due to the 1GHz frequency used by KVM.
To ensure that the guest doesn't have a conflicting view of the APIC bus
frequency, allow the userspace to tell KVM to use the same frequency that
TDX mandates instead of the default 1Ghz.

dma-buf: align fd_flags and heap_flags with dma_heap_allocation_data

struct dma_heap_allocation_data {
__u64 len;
__u32 fd;
__u32 fd_flags;

However, dma_heap_buffer_alloc() casts both fd_flags and heap_flags

TTY fix for 6.10-rc2
Here is a single revert for a much-reported regression in 6.10-rc1 when it comes to a few older architectures. Turns out that the VT ioctls don't work the same across all cpu types because of some old compatibility requrements for stuff like alpha and powerpc.

netdev: add qstat for csum complete
Recent commit 0cfe71f45f42 ("netdev: add queue stats") added
a lot of useful stats, but only those immediately needed by virtio.
Presumably virtio does not support CHECKSUM_COMPLETE,
so statistic for that form of checksumming wasn't included.
Other drivers will definitely need it, in fact we expect it
to be needed in net-next soon (mlx5). So let's add the definition
of the counter for CHECKSUM_COMPLETE to uAPI in net already,
so that the counters are in a more natural order (all subsequent
counters have not been present in any released kernel, yet).

virtio-mem: support suspend+resume
With virtio-mem, primarily hibernation is problematic: as the machine shuts down, the virtio-mem device loses its state. Powering the machine back up is like losing a bunch of DIMMs. While there would be ways to add limited support, suspend+resume is more commonly used for VMs and "easier" to support cleanly. s2idle can be supported without any device dependencies. Similarly, one would expect suspend-to-ram (i.e., S3) to work out of the box. However, QEMU currently unplugs all device memory when resuming the VM, using a cold reset on the "wakeup" path. In order to support S3, we need a feature flag for the device to tell us if memory remains plugged when waking up. In the future, QEMU will implement this feature. So let's always support s2idle and support S3 with plugged memory only if the device indicates support. Block hibernation early using the PM notifier. Trying to hibernate now fails early: # echo disk > /sys/power/state [ 26.455369] PM: hibernation: hibernation entry [ 26.458271] virtio_mem virtio0: hibernation is not supported.

reflect the actual functionality (Manivannan Sadhasivam)
- Call dw_pcie_ep_init_registers() directly from all the glue
drivers, not just those that require active Refclk from the host
(Manivannan Sadhasivam)
- Remove the "core_init_notifier" flag, which was an obscure way for
glue drivers to indicate that they depend on Refclk from the host
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Add DT binding J784S4 SoC Device ID (Siddharth Vadapalli)

bcachefs changes for 6.10-rc1
- More safety fixes, primarily found by syzbot - Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is primarily for testing fsck/recovery in dry run mode, so it shouldn't change anything besides disabling writes and holding dirty metadata in memory. The idea here was to reduce the amount of activity if we can't write anything out, so that bringing up a filesystem in "super ro" mode would be more lilkely to work for data recovery - but norecovery is the correct option for this. - btree_trans->locked; we now track whether a btree_trans has any btree nodes locked, and this is used for improved assertions related to trans_unlock() and trans_relock(). We'll also be using it for improving how we work with lockdep in the future: we don't want lockdep to be tracking individual btree node locks because we take too many for lockdep to track, and it's not necessary since we have a cycle detector. - Trigger improvements that are prep work for online fsck - BTREE_TRIGGER_check_repair; this regularizes how we do some repair work for extents that goes with running triggers in fsck, and fixes some subtle issues with transaction restarts there. - bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot equivalence classes are for when snapshot deletion leaves behind redundant snapshot nodes, but snapshot deletion now cleans this up right away, so the abstraction doesn't need to leak. - Improvements to how we resume writing to the journal in recovery.

Nochanges mode is primarily for testing fsck/recovery in dry run mode, so it shouldn't change anything besides disabling writes and holding dirty metadata in memory. The idea here was to reduce the amount of activity if we can't write anything out, so that bringing up a filesystem in "super ro" mode would be more lilkely to work for data recovery - but norecovery is the correct option for this. - btree_trans->locked; we now track whether a btree_trans has any btree nodes locked, and this is used for improved assertions related to trans_unlock() and trans_relock(). We'll also be using it for improving how we work with lockdep in the future: we don't want lockdep to be tracking individual btree node locks because we take too many for lockdep to track, and it's not necessary since we have a cycle detector. - Trigger improvements that are prep work for online fsck - BTREE_TRIGGER_check_repair; this regularizes how we do some repair work for extents that goes with running triggers in fsck, and fixes some subtle issues with transaction restarts there. - bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot equivalence classes are for when snapshot deletion leaves behind redundant snapshot nodes, but snapshot deletion now cleans this up right away, so the abstraction doesn't need to leak. - Improvements to how we resume writing to the journal in recovery.

NFSD 6.10 Release Notes
This is a light release containing mostly optimizations, code clean-
ups, and minor bug fixes. This development cycle has focused on non-
upstream kernel work:
1. Continuing to build upstream CI for NFSD, based on kdevops
2. Backporting NFSD filecache-related fixes to selected LTS kernels
One notable new feature in v6.10 NFSD is the addition of a new
netlink protocol dedicated to configuring NFSD. A new user space
tool, nfsdctl, is to be added to nfs-utils. Lots more to come here.
As always I am very grateful to NFSD contributors, reviewers,
testers, and bug reporters who participated during this cycle.

tracing ring buffer updates for v6.10:
- Add ring_buffer memory mappings The tracing ring buffer was created based on being mostly used with the splice system call. It is broken up into page ordered sub-buffers and the reader swaps a new sub-buffer with an existing sub-buffer that's part of the write buffer. It then has total access to the swapped out sub-buffer and can do copyless movements of the memory into other mediums (file system, network, etc). The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release. It can be enabled by compiling the library with a special flag. This was used for testing applications that perform better with the buffer being mapped. Memory mapped buffers have limitations. The main one is that it can not be used with the snapshot logic. If the buffer is mapped, snapshots will be disabled. If any logic is set to trigger snapshots on a buffer, that buffer will not be allowed to be mapped. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZkYzDRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qttNAQCj3I0OpeI1vms85ShIa7Eha2qes5uC Yml2fnapkmRSwAEAp5UTGxtDctycWOk9B9PA7/oJmLgATaQwRKoEeTUwfAA= =TyEB -----END PGP SIGNATURE----- Merge tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing ring buffer updates from Steven Rostedt: "Add ring_buffer memory mappings.

Merge tag 'cxl-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dave Jiang:
- Three CXL mailbox passthrough commands are added to support the
populating and clearing of vendor debug logs:
- Get Log Capabilities
- Get Supported Log Sub-List Commands
- Clear Log
- Add support of Device Phyiscal Address (DPA) to Host Physical Address
(HPA) translation for CXL events of cxl_dram and cxl_general media.
This allows user space to figure out which CXL region the event
occured via trace event.
- Connect CXL to CPER reporting.
If a device is configured for firmware first, CXL event records are
not sent directly to the host. Those records are reported through EFI
Common Platform Error Records (CPER). Add support to route the CPER
records through the CXL sub-system in order to provide DPA to HPA
translation and also event decoding and tracing. This is useful for
users to determine which system issues may correspond to specific
hardware events.
- A number of misc cleanups and fixes:
- Fix for compile warning of cxl_security_ops
- Add debug message for invalid interleave granularity
- Enhancement to cxl-test event testing
- Add dev_warn() on unsupported mixed mode decoder
- Fix use of phys_to_target_node() for x86
- Use helper function for decoder enum instead of open coding
- Include missing headers for cxl-event
- Fix MAINTAINERS file entry

Networking changes for 6.10.
Core & protocols
----------------
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd passing
functionality. New method based on Tarjan's Strongly Connected Components
algorithm should be both faster and remove a lot of workarounds
we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP packets
and forwarding them together. Useful for small switches / routers which
lack basic checksum offload in some scenarios (e.g. PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't
use NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory accounting,
RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked,
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states.
State can be used either for input or output packet processing.
Things we sprinkled into general kernel code
--------------------------------------------
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter
---------
- Use GFP_KERNEL to clone elements, to deal better with OOM situations
and avoid failures in the .commit step.
BPF
---
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function entry
and return, the entry program can decide if the return program gets
executed and the entry program can share u64 cookie value with return
program. "Session mode" is a common use-case for tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw tracepoint
programs in order to ease migration from classic to raw tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V JITs.
This allows inlining functions which need to access per-CPU state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86 instruction.
Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor process-context
bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API
----------
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line) config.
- Initial bits of a queue control API, for now allowing a single queue
to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling
-----------------
- Remove the need to create a config file to run the net forwarding tests
so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test machine).
Add a few such tests.
- Create a shared code library for writing Python tests. Expose the YAML
Netlink library from tools/ to the tests for easy Netlink access.
- Move netfilter tests under net/, extend them, separate performance tests
from correctness tests, and iron out issues found by running them
"on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF info,
TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers
-------
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application rather
than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):
- support multiple RSS contexts and steering traffic to them

Bluetooth: HCI: Remove HCI_AMP support
Since BT_HS has been remove HCI_AMP controllers no longer has any use so
remove it along with the capability of creating AMP controllers.
Since we no longer need to differentiate between AMP and Primary
controllers, as only HCI_PRIMARY is left, this also remove

net: revert partially applied PHY topology series
The series is causing issues with PHY drivers built as modules.
Since it was only partially applied and the merge window has
opened let's revert and try again for v6.11.
Revert 6916e461e793 ("net: phy: Introduce ethernet link topology representation")
Revert 0ec5ed6c130e ("net: sfp: pass the phy_device when disconnecting an sfp module's PHY")
Revert e75e4e074c44 ("net: phy: add helpers to handle sfp phy connect/disconnect")
Revert fdd353965b52 ("net: sfp: Add helper to return the SFP bus name")
Revert 841942bc6212 ("net: ethtool: Allow passing a phy index for some commands")
