net/sched: mqprio: allow per-TC user input of FP adminStatus
IEEE 802.1Q-2018 clause 6.7.2 Frame preemption specifies that each packet priority can be assigned to a "frame preemption status" value of either "express" or "preemptible". Express priorities are transmitted by the local device through the eMAC, and preemptible priorities through the pMAC (the concepts of eMAC and pMAC come from the 802.3 MAC Merge layer). The FP adminStatus is defined per packet priority, but 802.1Q clause 12.30.1.1.1 framePreemptionAdminStatus also says that: | Priorities that all map to the same traffic class should be | constrained to use the same value of preemption status. It is impossible to ignore the cognitive dissonance in the standard here, because it practically means that the FP adminStatus only takes distinct values per traffic class, even though it is defined per priority. I can see no valid use case which is prevented by having the kernel take the FP adminStatus as input per traffic class (what we do here). In addition, this also enforces the above constraint by construction. User space network managers which wish to expose FP adminStatus per priority are free to do so; they must only observe the prio_tc_map of the netdev (which presumably is also under their control, when constructing the mqprio netlink attributes). The reason for configuring frame preemption as a property of the Qdisc layer is that the information about "preemptible TCs" is closest to the place which handles the num_tc and prio_tc_map of the netdev. If the UAPI would have been any other layer, it would be unclear what to do with the FP information when num_tc collapses to 0. A key assumption is that only mqprio/taprio change the num_tc and prio_tc_map of the netdev. Not sure if that's a great assumption to make. Having FP in tc-mqprio can be seen as an implementation of the use case defined in 802.1Q Annex S.2 "Preemption used in isolation". There will be a separate implementation of FP in tc-taprio, for the other use cases.

bpf: Add log_true_size output field to return necessary log buffer size
Add output-only log_true_size and btf_log_true_size field to BPF_PROG_LOAD and BPF_BTF_LOAD commands, respectively. It will return the size of log buffer necessary to fit in all the log contents at specified log_level. This is very useful for BPF loader libraries like libbpf to be able to size log buffer correctly, but could be used by users directly, if necessary, as well. This patch plumbs all this through the code, taking into account actual bpf_attr size provided by user to determine if these new fields are expected by users. And if they are, set them from kernel on return. We refactory btf_parse() function to accommodate this, moving attr and uattr handling inside it. The rest is very straightforward code, which is split from the logging accounting changes in the previous patch to make it simpler to review logic vs UAPI changes.

mm: userfaultfd: add UFFDIO_CONTINUE_MODE_WP to install WP PTEs
UFFDIO_COPY already has UFFDIO_COPY_MODE_WP, so when installing a new PTE
to resolve a missing fault, one can install a write-protected one. This
is useful when using UFFDIO_REGISTER_MODE_{MISSING,WP} in combination.
This was motivated by testing HugeTLB HGM [1], and in particular its
interaction with userfaultfd features. Existing userfaultfd code supports
using WP and MINOR modes together (i.e. you can register an area with
both enabled), but without this CONTINUE flag the combination is in
practice unusable.
So, add an analogous UFFDIO_CONTINUE_MODE_WP, which does the same thing as
UFFDIO_COPY_MODE_WP, but for *minor* faults.
Update the selftest to do some very basic exercising of the new flag.
Update Documentation/ to describe how these flags are used (neither the
COPY nor the new CONTINUE versions of this mode flag were described there
before).

mm/uffd: UFFD_FEATURE_WP_UNPOPULATED
Patch series "mm/uffd: Add feature bit UFFD_FEATURE_WP_UNPOPULATED", v4.
The new feature bit makes anonymous memory acts the same as file memory on
userfaultfd-wp in that it'll also wr-protect none ptes.
It can be useful in two cases:
(1) Uffd-wp app that needs to wr-protect none ptes like QEMU snapshot,
so pre-fault can be replaced by enabling this flag and speed up
protections
(2) It helps to implement async uffd-wp mode that Muhammad is working on [1]
It's debatable whether this is the most ideal solution because with the
new feature bit set, wr-protect none pte needs to pre-populate the
pgtables to the last level (PAGE_SIZE). But it seems fine so far to
service either purpose above, so we can leave optimizations for later.
The series brings pte markers to anonymous memory too. There's some
change in the common mm code path in the 1st patch, great to have some eye
looking at it, but hopefully they're still relatively straightforward.
This patch (of 2):
This is a new feature that controls how uffd-wp handles none ptes. When
it's set, the kernel will handle anonymous memory the same way as file
memory, by allowing the user to wr-protect unpopulated ptes.
File memories handles none ptes consistently by allowing wr-protecting of
none ptes because of the unawareness of page cache being exist or not.
For anonymous it was not as persistent because we used to assume that we
don't need protections on none ptes or known zero pages.
One use case of such a feature bit was VM live snapshot, where if without
wr-protecting empty ptes the snapshot can contain random rubbish in the
holes of the anonymous memory, which can cause misbehave of the guest when
the guest OS assumes the pages should be all zeros.
QEMU worked it around by pre-populate the section with reads to fill in
zero page entries before starting the whole snapshot process [1].
Recently there's another need raised on using userfaultfd wr-protect for
detecting dirty pages (to replace soft-dirty in some cases) [2]. In that
case if without being able to wr-protect none ptes by default, the dirty
info can get lost, since we cannot treat every none pte to be dirty (the
current design is identify a page dirty based on uffd-wp bit being
cleared).
In general, we want to be able to wr-protect empty ptes too even for
anonymous.
This patch implements UFFD_FEATURE_WP_UNPOPULATED so that it'll make
uffd-wp handling on none ptes being consistent no matter what the memory
type is underneath. It doesn't have any impact on file memories so far
because we already have pte markers taking care of that. So it only
affects anonymous.
The feature bit is by default off, so the old behavior will be maintained.
Sometimes it may be wanted because the wr-protect of none ptes will
contain overheads not only during UFFDIO_WRITEPROTECT (by applying pte
markers to anonymous), but also on creating the pgtables to store the pte
markers. So there's potentially less chance of using thp on the first
fault for a none pmd or larger than a pmd.
The major implementation part is teaching the whole kernel to understand
pte markers even for anonymously mapped ranges, meanwhile allowing the
UFFDIO_WRITEPROTECT ioctl to apply pte markers for anonymous too when the
new feature bit is set.
Note that even if the patch subject starts with mm/uffd, there're a few
small refactors to major mm path of handling anonymous page faults. But
they should be straightforward.
With WP_UNPOPUATED, application like QEMU can avoid pre-read faults all
the memory before wr-protect during taking a live snapshot. Quotting from
Muhammad's test result here [3] based on a simple program [4]:
(1) With huge page disabled
echo madvise > /sys/kernel/mm/transparent_hugepage/enabled
./uffd_wp_perf
Test DEFAULT: 4
Test PRE-READ: 1111453 (pre-fault

virtio-blk: fix to match virtio spec
The merged patch series to support zoned block devices in virtio-blk
is not the most up to date version. The merged patch can be found at
https://lore.kernel.org/linux-block/20221016034127.330942-3-dmitry.fomichev@wdc.com/
but the latest and reviewed version is
https://lore.kernel.org/linux-block/20221110053952.3378990-3-dmitry.fomichev@wdc.com/
The reason is apparently that the correct mailing lists and
maintainers were not copied.
The differences between the two are mostly cleanups, but there is one
change that is very important in terms of compatibility with the
approved virtio-zbd specification.
Before it was approved, the OASIS virtio spec had a change in
VIRTIO_BLK_T_ZONE_APPEND request layout that is not reflected in the
current virtio-blk driver code. In the running code, the status is
the first byte of the in-header that is followed by some pad bytes
and the u64 that carries the sector at which the data has been written
to the zone back to the driver, aka the append sector.
This layout turned out to be problematic for implementing in QEMU and
the request status byte has been eventually made the last byte of the
in-header. The current code doesn't expect that and this causes the
append sector value always come as zero to the block layer. This needs
to be fixed ASAP.
Fixes:

io_uring: add support for user mapped provided buffer ring
The ring mapped provided buffer rings rely on the application allocating the memory for the ring, and then the kernel will map it. This generally works fine, but runs into issues on some architectures where we need to be able to ensure that the kernel and application virtual address for the ring play nicely together. This at least impacts architectures that set SHM_COLOUR, but potentially also anyone setting SHMLBA. To use this variant of ring provided buffers, the application need not allocate any memory for the ring. Instead the kernel will do so, and the allocation must subsequently call mmap(2) on the ring with the offset set to: IORING_OFF_PBUF_RING | (bgid << IORING_OFF_PBUF_SHIFT) to get a virtual address for the buffer ring. Normally the application would allocate a suitable piece of memory (and correctly aligned) and simply pass that in via io_uring_buf_reg.ring_addr and the kernel would map it. Outside of the setup differences, the kernel allocate + user mapped provided buffer ring works exactly the same. Acked-by: Helge Deller <deller@gmx.de> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

dm: split discards further if target sets max_discard_granularity
The block core (bio_split_discard) will already split discards based on the 'discard_granularity' and 'max_discard_sectors' queue_limits. But the DM thin target also needs to ensure that it doesn't receive a discard that spans a 'max_discard_sectors' boundary. Introduce a dm_target 'max_discard_granularity' flag that if set will cause DM core to split discard bios relative to 'max_discard_sectors'. This treats 'discard_granularity' as a "min_discard_granularity" and 'max_discard_sectors' as a "max_discard_granularity".

Merge tag 'dma-fence-deadline' of https://gitlab.freedesktop.org/drm/msm into drm-next
This series adds a deadline hint to fences, so realtime deadlines such as vblank can be communicated to the fence signaller for power/ frequency management decisions. This is partially inspired by a trick i915 does, but implemented via dma-fence for a couple of reasons: 1) To continue to be able to use the atomic helpers 2) To support cases where display and gpu are different drivers See https://patchwork.freedesktop.org/series/93035/ This does not yet add any UAPI, although this will be needed in a number of cases: 1) Workloads "ping-ponging" between CPU and GPU, where we don't want the GPU freq governor to interpret time stalled waiting for GPU as "idle" time 2) Cases where the compositor is waiting for fences to be signaled before issuing the atomic ioctl, for example to maintain 60fps cursor updates even when the GPU is not able to maintain that framerate.

tracing/user_events: Add ioctl for disabling addresses
Enablements are now tracked by the lifetime of the task/mm. User processes need to be able to disable their addresses if tracing is requested to be turned off. Before unmapping the page would suffice. However, we now need a stronger contract. Add an ioctl to enable this. A new flag bit is added, freeing, to user_event_enabler to ensure that if the event is attempted to be removed while a fault is being handled that the remove is delayed until after the fault is reattempted.

tracing/user_events: Use remote writes for event enablement
As part of the discussions for user_events aligned with user space tracers, it was determined that user programs should register a aligned value to set or clear a bit when an event becomes enabled. Currently a shared page is being used that requires mmap(). Remove the shared page implementation and move to a user registered address implementation. In this new model during the event registration from user programs 3 new values are specified. The first is the address to update when the event is either enabled or disabled. The second is the bit to set/clear to reflect the event being enabled. The third is the size of the value at the specified address. This allows for a local 32/64-bit value in user programs to support both kernel and user tracers. As an example, setting bit 31 for kernel tracers when the event becomes enabled allows for user tracers to use the other bits for ref counts or other flags. The kernel side updates the bit atomically, user programs need to also update these values atomically. User provided addresses must be aligned on a natural boundary, this allows for single page checking and prevents odd behaviors such as a enable value straddling 2 pages instead of a single page. Currently page faults are only logged, future patches will handle these.

macvlan: Add netlink attribute for broadcast cutoff
Make the broadcast cutoff configurable through netlink. Note that macvlan is weird because there is no central device for us to configure (the lowerdev could be anything). So all the options are duplicated over what could be thousands of child devices. IFLA_MACVLAN_BC_QUEUE_LEN took the approach of taking the maximum of all child device settings. This is unnecessary as we could simply store the option in the port device and take the last child device that gets updated as the value to use.

cfg80211: support RNR for EMA AP
As per IEEE Std 802.11ax-2021, 11.1.3.8.3 Discovery of a nontransmitted BSSID profile, an EMA AP that transmits a Beacon frame carrying a partial list of nontransmitted BSSID profiles should include in the frame a Reduced Neighbor Report element carrying information for at least the nontransmitted BSSIDs that are not present in the Multiple BSSID element carried in that frame. Add new nested attribute NL80211_ATTR_EMA_RNR_ELEMS to support the above. Number of RNR elements must be more than or equal to the number of MBSSID elements. This attribute can be used only when EMA is enabled. Userspace is responsible for splitting the RNR into multiple elements such that each element excludes the non-transmitting profiles already included in the MBSSID element (%NL80211_ATTR_MBSSID_ELEMS) at the same index. Each EMA beacon will be generated by adding MBSSID and RNR elements at the same index. If the userspace provides more RNR elements than the number of MBSSID elements then these will be added in every EMA beacon.

bpf: Create links for BPF struct_ops maps.
Make bpf_link support struct_ops. Previously, struct_ops were always used alone without any associated links. Upon updating its value, a struct_ops would be activated automatically. Yet other BPF program types required to make a bpf_link with their instances before they could become active. Now, however, you can create an inactive struct_ops, and create a link to activate it later. With bpf_links, struct_ops has a behavior similar to other BPF program types. You can pin/unpin them from their links and the struct_ops will be deactivated when its link is removed while previously need someone to delete the value for it to be deactivated. bpf_links are responsible for registering their associated struct_ops. You can only use a struct_ops that has the BPF_F_LINK flag set to create a bpf_link, while a structs without this flag behaves in the same manner as before and is registered upon updating its value. The BPF_LINK_TYPE_STRUCT_OPS serves a dual purpose. Not only is it used to craft the links for BPF struct_ops programs, but also to create links for BPF struct_ops them-self. Since the links of BPF struct_ops programs are only used to create trampolines internally, they are never seen in other contexts. Thus, they can be reused for struct_ops themself. To maintain a reference to the map supporting this link, we add bpf_struct_ops_link as an additional type. The pointer of the map is RCU and won't be necessary until later in the patchset.

x86/sev: Change snp_guest_issue_request()'s fw_err argument
The GHCB specification declares that the firmware error value for a guest request will be stored in the lower 32 bits of EXIT_INFO_2. The upper 32 bits are for the VMM's own error code. The fw_err argument to snp_guest_issue_request() is thus a misnomer, and callers will need access to all 64 bits. The type of unsigned long also causes problems, since sw_exit_info2 is u64 (unsigned long long) vs the argument's unsigned long*. Change this type for issuing the guest request. Pass the ioctl command struct's error field directly instead of in a local variable, since an incomplete guest request may not set the error code, and uninitialized stack memory would be written back to user space. The firmware might not even be called, so bookend the call with the no firmware call error and clear the error. Since the "fw_err" field is really exitinfo2 split into the upper bits' vmm error code and lower bits' firmware error code, convert the 64 bit value to a union.

vxlan: mdb: Add MDB control path support
Implement MDB control path support, enabling the creation, deletion, replacement and dumping of MDB entries in a similar fashion to the bridge driver. Unlike the bridge driver, each entry stores a list of remote VTEPs to which matched packets need to be replicated to and not a list of bridge ports. The motivating use case is the installation of MDB entries by a user space control plane in response to received EVPN routes. As such, only allow permanent MDB entries to be installed and do not implement snooping functionality, avoiding a lot of unnecessary complexity. Since entries can only be modified by user space under RTNL, use RTNL as the write lock. Use RCU to ensure that MDB entries and remotes are not freed while being accessed from the data path during transmission. In terms of uAPI, reuse the existing MDB netlink interface, but add a few new attributes to request and response messages: * IP address of the destination VXLAN tunnel endpoint where the multicast receivers reside. * UDP destination port number to use to connect to the remote VXLAN tunnel endpoint. * VXLAN VNI Network Identifier to use to connect to the remote VXLAN tunnel endpoint. Required when Ingress Replication (IR) is used and the remote VTEP is not a member of originating broadcast domain (VLAN/VNI) [1]. * Source VNI Network Identifier the MDB entry belongs to. Used only when the VXLAN device is in external mode. * Interface index of the outgoing interface to reach the remote VXLAN tunnel endpoint. This is required when the underlay destination IP is multicast (P2MP), as the multicast routing tables are not consulted. All the new attributes are added under the 'MDBA_SET_ENTRY_ATTRS' nest which is strictly validated by the bridge driver, thereby automatically rejecting the new attributes.

ynl: broaden the license even more
I relicensed Netlink spec code to GPL-2.0 OR BSD-3-Clause but
we still put a slightly different license on the uAPI header
than the rest of the code. Use the Linux-syscall-note on all
the specs and all generated code. It's moot for kernel code,
but should not hurt. This way the licenses match everywhere.

platform/x86: ISST: Add SST-TF support via TPMI
The support of Intel Speed Select Technology - Turbo Frequency (SST-TF) feature enables the ability to set different “All core turbo ratio limits” to cores based on the priority. By using this feature, some cores can be configured to get higher turbo frequency by designating them as high priority at the cost of lower or no turbo frequency on the low priority cores. One new IOCTLs are added: ISST_IF_GET_TURBO_FREQ_INFO : Get information about turbo frequency buckets Once an instance is identified, read or write from correct MMIO offset for a given field as defined in the specification.

platform/x86: ISST: Add SST-CP support via TPMI
Intel Speed Select Technology Core Power (SST-CP) is an interface that allows users to define per core priority. This defines a mechanism to distribute power among cores when there is a power constrained scenario. This defines a class of service (CLOS) configuration. Three new IOCTLs are added: ISST_IF_CORE_POWER_STATE : Enable/Disable SST-CP ISST_IF_CLOS_PARAM : Configure CLOS parameters ISST_IF_CLOS_ASSOC : Associate CPUs to a CLOS To associate CPUs to CLOS, either Linux CPU numbering or PUNIT numbering scheme can be used, using parameter punit_cpu_map (1: for PUNIT numbering 0 for Linux CPU number). There is no change to IOCTL to get PUNIT CPU number for a CPU. Introduce get_instance() function, which is used by majority of IOCTLs processing to convert a socket and power domain to tpmi_per_power_domain_info * instance. This instance has all the MMIO offsets stored to read a particular field. Once an instance is identified, read or write from correct MMIO offset for a given field as defined in the specification.

platform/x86: ISST: Enumerate TPMI SST and create framework
Enumerate TPMI SST driver and create basic framework to add more features. The basic user space interface is still same as the legacy using /dev/isst_interface. Users of "intel-speed-select" utility should be able to use same commands as prior gens without being aware of new underlying hardware interface. TPMI SST driver enumerates on device "intel_vsec.tpmi-sst". Since there can be multiple instances and there is one common SST core, split implementation into two parts: A common core part and an enumeration part. The enumeration driver is loaded for each device instance and register with the TPMI SST core driver. On very first enumeration the TPMI SST core driver register with SST core driver to get IOCTL callbacks. The api_version is incremented for IOCTL ISST_IF_GET_PLATFORM_INFO, so that user space can issue new IOCTLs. Each TPMI package contains multiple power domains. Each power domain has its own set of SST controls. For each domain map the MMIO memory and update per domain struct tpmi_per_power_domain_info. This information will be used to implement other SST interfaces. Implement first IOCTL commands to get number of TPMI SST instances and instance mask as some of the power domains may not have any SST controls.

bpf: use canonical ftrace path
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing Many comments and samples in the bpf code still refer to this older debugfs path, so let's update them to avoid confusion. There are a few spots where the bpf code explicitly checks both tracefs and debugfs (tools/bpf/bpftool/tracelog.c and tools/lib/api/fs/fs.c) and I've left those alone so that the tools can continue to work with both paths.

net: virtio_net: implement exact header length guest feature
Virtio spec introduced a feature VIRTIO_NET_F_GUEST_HDRLEN which when set implicates that device benefits from knowing the exact size of the header. For compatibility, to signal to the device that the header is reliable driver also needs to set this feature. Without this feature set by driver, device has to figure out the header size itself. Quoting the original virtio spec: "hdr_len is a hint to the device as to how much of the header needs to be kept to copy into each packet" "a hint" might not be clear for the reader what does it mean, if it is "maybe like that" of "exactly like that". This feature just makes it crystal clear and let the device count on the hdr_len being filled up by the exact length of header. Also note the spec already has following note about hdr_len: "Due to various bugs in implementations, this field is not useful as a guarantee of the transport header size." Without this feature the device needs to parse the header in core data path handling. Accurate information helps the device to eliminate such header parsing and directly use the hardware accelerators for GSO operation. virtio_net_hdr_from_skb() fills up hdr_len to skb_headlen(skb). The driver already complies to fill the correct value. Introduce the feature and advertise it. Note that virtio spec also includes following note for device implementation: "Caution should be taken by the implementation so as to prevent a malicious driver from attacking the device by setting an incorrect hdr_len." There is a plan to support this feature in our emulated device. A device of SolidRun offers this feature bit. They claim this feature will save the device a few cycles for every GSO packet.

char: pcmcia: remove all the drivers
These char PCMCIA drivers are buggy[1] and receive only minimal care. It was concluded[2], that we should try to remove most pcmcia drivers completely. Let's start with these char broken one. Note that I also removed a UAPI header: include/uapi/linux/cm4000_cs.h. I found only coccinelle tests mentioning some ioctl constants from that file. But they are not actually used. Anyway, should someone complain, we may reintroduce the header (or its parts).

sctp: add weighted fair queueing stream scheduler
As it says in rfc8260#section-3.6 about the weighted fair queueing scheduler: A Weighted Fair Queueing scheduler between the streams is used. The weight is configurable per outgoing SCTP stream. This scheduler considers the lengths of the messages of each stream and schedules them in a specific way to use the capacity according to the given weights. If the weight of stream S1 is n times the weight of stream S2, the scheduler should assign to stream S1 n times the capacity it assigns to stream S2. The details are implementation dependent. Interleaving user messages allows for a better realization of the capacity usage according to the given weights. This patch adds Weighted Fair Queueing Scheduler actually based on the code of Fair Capacity Scheduler by adding fc_weight into struct sctp_stream_out_ext and taking it into account when sorting stream-> fc_list in sctp_sched_fc_sched() and sctp_sched_fc_dequeue_done().

bpf: implement numbers iterator
Implement the first open-coded iterator type over a range of integers.
It's public API consists of:
- bpf_iter_num_new() constructor, which accepts [start, end) range
(that is, start is inclusive, end is exclusive).
- bpf_iter_num_next() which will keep returning read-only pointer to int
until the range is exhausted, at which point NULL will be returned.
If bpf_iter_num_next() is kept calling after this, NULL will be
persistently returned.
- bpf_iter_num_destroy() destructor, which needs to be called at some
point to clean up iterator state. BPF verifier enforces that iterator
destructor is called at some point before BPF program exits.
Note that `start = end = X` is a valid combination to setup an empty
iterator. bpf_iter_num_new() will return 0 (success) for any such
combination.
If bpf_iter_num_new() detects invalid combination of input arguments, it
returns error, resets iterator state to, effectively, empty iterator, so
any subsequent call to bpf_iter_num_next() will keep returning NULL.
BPF verifier has no knowledge that returned integers are in the
[start, end) value range, as both `start` and `end` are not statically
known and enforced: they are runtime values.
While the implementation is pretty trivial, some care needs to be taken
to avoid overflows and underflows. Subsequent selftests will validate
correctness of [start, end) semantics, especially around extremes
(INT_MIN and INT_MAX).
Similarly to bpf_loop(), we enforce that no more than BPF_MAX_LOOPS can
be specified.
bpf_iter_num_{new,next,destroy}() is a logical evolution from bounded
BPF loops and bpf_loop() helper and is the basis for implementing
ergonomic BPF loops with no statically known or verified bounds.
Subsequent patches implement bpf_for() macro, demonstrating how this can
be wrapped into something that works and feels like a normal for() loop
in C language.

ynl: re-license uniformly under GPL-2.0 OR BSD-3-Clause
I was intending to make all the Netlink Spec code BSD-3-Clause to ease the adoption but it appears that: - I fumbled the uAPI and used "GPL WITH uAPI note" there - it gives people pause as they expect GPL in the kernel As suggested by Chuck re-license under dual. This gives us benefit of full BSD freedom while fulfilling the broad "kernel is under GPL" expectations.

wifi: nl80211: Add support for randomizing TA of auth and deauth frames
Add support to use a random local address in authentication and deauthentication frames sent to unassociated peer when the driver supports. The driver needs to configure receive behavior to accept frames with random transmit address specified in TX path authentication frames during the time of the frame exchange is pending and such frames need to be acknowledged similarly to frames sent to the local permanent address when this random address functionality is used. This capability allows use of randomized transmit address for PASN authentication frames to improve privacy of WLAN clients.

bpf: Add support for absolute value BPF timers
Add a new flag BPF_F_TIMER_ABS that can be passed to bpf_timer_start() to start an absolute value timer instead of the default relative value. This makes the timer expire at an exact point in time, instead of a time with latencies induced by both the BPF and timer subsystems.

bpf: Add bpf_dynptr_slice and bpf_dynptr_slice_rdwr
Two new kfuncs are added, bpf_dynptr_slice and bpf_dynptr_slice_rdwr. The user must pass in a buffer to store the contents of the data slice if a direct pointer to the data cannot be obtained. For skb and xdp type dynptrs, these two APIs are the only way to obtain a data slice. However, for other types of dynptrs, there is no difference between bpf_dynptr_slice(_rdwr) and bpf_dynptr_data. For skb type dynptrs, the data is copied into the user provided buffer if any of the data is not in the linear portion of the skb. For xdp type dynptrs, the data is copied into the user provided buffer if the data is between xdp frags. If the skb is cloned and a call to bpf_dynptr_data_rdwr is made, then the skb will be uncloned (see bpf_unclone_prologue()). Please note that any bpf_dynptr_write() automatically invalidates any prior data slices of the skb dynptr. This is because the skb may be cloned or may need to pull its paged buffer into the head. As such, any bpf_dynptr_write() will automatically have its prior data slices invalidated, even if the write is to data in the skb head of an uncloned skb. Please note as well that any other helper calls that change the underlying packet buffer (eg bpf_skb_pull_data()) invalidates any data slices of the skb dynptr as well, for the same reasons.

bpf: Add xdp dynptrs
Add xdp dynptrs, which are dynptrs whose underlying pointer points to a xdp_buff. The dynptr acts on xdp data. xdp dynptrs have two main benefits. One is that they allow operations on sizes that are not statically known at compile-time (eg variable-sized accesses). Another is that parsing the packet data through dynptrs (instead of through direct access of xdp->data and xdp->data_end) can be more ergonomic and less brittle (eg does not need manual if checking for being within bounds of data_end). For reads and writes on the dynptr, this includes reading/writing from/to and across fragments. Data slices through the bpf_dynptr_data API are not supported; instead bpf_dynptr_slice() and bpf_dynptr_slice_rdwr() should be used. For examples of how xdp dynptrs can be used, please see the attached selftests.

Another is that parsing the packet data through dynptrs (instead of through direct access of skb->data and skb->data_end) can be more ergonomic and less brittle (eg does not need manual if checking for being within bounds of data_end). For bpf prog types that don't support writes on skb data, the dynptr is read-only (bpf_dynptr_write() will return an error) For reads and writes through the bpf_dynptr_read() and bpf_dynptr_write() interfaces, reading and writing from/to data in the head as well as from/to non-linear paged buffers is supported. Data slices through the bpf_dynptr_data API are not supported; instead bpf_dynptr_slice() and bpf_dynptr_slice_rdwr() (added in subsequent commit) should be used.

drm/amdkfd: Implement DMA buf fd export from KFD
Exports a DMA buf fd of a given KFD buffer handle. This is intended for being able to import KFD BOs into GEM contexts to leverage the amdgpu_bo_va API for more flexible virtual address mappings. It will also be used for the new upstreamable RDMA solution coming to UCX and RCCL.

- Remove redundant resource check in vfio-platform. (Angus Chen)
- Use GFP_KERNEL_ACCOUNT for persistent userspace allocations, allowing
removal of arbitrary kernel limits in favor of cgroup control.
(Yishai Hadas)
- mdev tidy-ups, including removing the module-only build restriction
for sample drivers, Kconfig changes to select mdev support,
documentation movement to keep sample driver usage instructions with
sample drivers rather than with API docs, remove references to
out-of-tree drivers in docs. (Christoph Hellwig)
- Fix collateral breakages from mdev Kconfig changes. (Arnd Bergmann)
- Make mlx5 migration support match device support, improve source
and target flows to improve pre-copy support and reduce downtime.
(Yishai Hadas)
- Convert additional mdev sysfs case to use sysfs_emit(). (Bo Liu)
- Resolve copy-paste error in mdev mbochs sample driver Kconfig.
(Ye Xingchen)
- Avoid propagating missing reset error in vfio-platform if reset
requirement is relaxed by module option. (Tomasz Duszynski)
- Range size fixes in mlx5 variant driver for missed last byte and
stricter range calculation. (Yishai Hadas)
- Fixes to suspended vaddr support and locked_vm accounting, excluding
mdev configurations from the former due to potential to indefinitely
block kernel threads, fix underflow and restore locked_vm on new mm.
(Steve Sistare)
- Update outdated vfio documentation due to new IOMMUFD interfaces in
recent kernels. (Yi Liu)
- Resolve deadlock between group_lock and kvm_lock, finally.
(Matthew Rosato)
- Fix NULL pointer in group initialization error path with IOMMUFD.

ARM:
- Provide a virtual cache topology to the guest to avoid
inconsistencies with migration on heterogenous systems. Non secure
software has no practical need to traverse the caches by set/way in
the first place.
- Add support for taking stage-2 access faults in parallel. This was an
accidental omission in the original parallel faults implementation,
but should provide a marginal improvement to machines w/o FEAT_HAFDBS
(such as hardware from the fruit company).
- A preamble to adding support for nested virtualization to KVM,
including vEL2 register state, rudimentary nested exception handling
and masking unsupported features for nested guests.
- Fixes to the PSCI relay that avoid an unexpected host SVE trap when
resuming a CPU when running pKVM.
- VGIC maintenance interrupt support for the AIC
- Improvements to the arch timer emulation, primarily aimed at reducing
the trap overhead of running nested.
- Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
interest of CI systems.
- Avoid VM-wide stop-the-world operations when a vCPU accesses its own
redistributor.
- Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions
in the host.
- Aesthetic and comment/kerneldoc fixes
- Drop the vestiges of the old Columbia mailing list and add [Oliver]
as co-maintainer
This also drags in arm64's 'for-next/sme2' branch, because both it and
the PSCI relay changes touch the EL2 initialization code.
RISC-V:
- Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE
- Correctly place the guest in S-mode after redirecting a trap to the guest
- Redirect illegal instruction traps to guest
- SBI PMU support for guest
s390:
- Two patches sorting out confusion between virtual and physical
addresses, which currently are the same on s390.
- A new ioctl that performs cmpxchg on guest memory
- A few fixes
x86:
- Change tdp_mmu to a read-only parameter
- Separate TDP and shadow MMU page fault paths
- Enable Hyper-V invariant TSC control
- Fix a variety of APICv and AVIC bugs, some of them real-world,
some of them affecting architecurally legal but unlikely to
happen in practice
- Mark APIC timer as expired if its in one-shot mode and the count
underflows while the vCPU task was being migrated
- Advertise support for Intel's new fast REP string features
- Fix a double-shootdown issue in the emergency reboot code
- Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give SVM
similar treatment to VMX
- Update Xen's TSC info CPUID sub-leaves as appropriate
- Add support for Hyper-V's extended hypercalls, where "support" at this
point is just forwarding the hypercalls to userspace
- Clean up the kvm->lock vs. kvm->srcu sequences when updating the PMU and
MSR filters
- One-off fixes and cleanups
- Fix and cleanup the range-based TLB flushing code, used when KVM is
running on Hyper-V
- Add support for filtering PMU events using a mask. If userspace
wants to restrict heavily what events the guest can use, it can now
do so without needing an absurd number of filter entries
- Clean up KVM's handling of "PMU MSRs to save", especially when vPMU
support is disabled
- Add PEBS support for Intel Sapphire Rapids
- Fix a mostly benign overflow bug in SEV's send|receive_update_data()
- Move several SVM-specific flags into vcpu_svm
x86 Intel:
- Handle NMI VM-Exits before leaving the noinstr region
- A few trivial cleanups in the VM-Enter flows
- Stop enabling VMFUNC for L1 purely to document that KVM doesn't support
EPTP switching (or any other VM function) for L1
- Fix a crash when using eVMCS's enlighted MSR bitmaps
Generic:
- Clean up the hardware enable and initialization flow, which was
scattered around multiple arch-specific hooks. Instead, just
let the arch code call into generic code. Both x86 and ARM should
benefit from not having to fight common KVM code's notion of how
to do initialization.
- Account allocations in generic kvm_arch_alloc_vm()
- Fix a memory leak if coalesced MMIO unregistration fails
selftests:
- On x86, cache the CPU vendor (AMD vs. Intel) and use the info to emit
the correct hypercall instruction instead of relying on KVM to patch
in VMMCALL
- Use TAP interface for kvm_binary_stats_test and tsc_msrs_test

Pull Compute Express Link (CXL) updates from Dan Williams:
"To date Linux has been dependent on platform-firmware to map CXL RAM
regions and handle events / errors from devices. With this update we
can now parse / update the CXL memory layout, and report events /
errors from devices. This is a precursor for the CXL subsystem to
handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that
for DDR-attached-DRAM is handled by the EDAC driver where it maps
system physical address events to a field-replaceable-unit (FRU /
endpoint device). In general, CXL has the potential to standardize
what has historically been a pile of memory-controller-specific error
handling logic.
Another change of note is the default policy for handling RAM-backed
device-dax instances. Previously the default access mode was "device",
mmap(2) a device special file to access memory. The new default is
"kmem" where the address range is assigned to the core-mm via
add_memory_driver_managed(). This saves typical users from wondering
why their platform memory is not visible via free(1) and stuck behind
a device-file. At the same time it allows expert users to deploy
policy to, for example, get dedicated access to high performance
memory, or hide low performance memory from general purpose kernel
allocations. This affects not only CXL, but also systems with
high-bandwidth-memory that platform-firmware tags with the
EFI_MEMORY_SP (special purpose) designation.
Summary:
- CXL RAM region enumeration: instantiate 'struct cxl_region' objects
for platform firmware created memory regions
- CXL RAM region provisioning: complement the existing PMEM region
creation support with RAM region support
- "Soft Reservation" policy change: Online (memory hot-add)

Char/Misc and other driver subsystem changes for 6.3-rc1
Here is the large set of driver changes for char/misc drivers and other
smaller driver subsystems that flow through this git tree.
Included in here are:
- New IIO drivers and features and improvments in that subsystem
- New hwtracing drivers and additions to that subsystem
- lots of interconnect changes and new drivers as that subsystem seems
under very active development recently. This required also merging
in the icc subsystem changes through this tree.
- FPGA driver updates
- counter subsystem and driver updates
- MHI driver updates
- nvmem driver updates
- documentation updates
- Other smaller driver updates and fixes, full details in the shortlog
All of these have been in linux-next for a while with no reported

- Daniel Verkamp has contributed a memfd series ("mm/memfd: add
F_SEAL_EXEC") which permits the setting of the memfd execute bit at
memfd creation time, with the option of sealing the state of the X bit.
- Peter Xu adds a patch series ("mm/hugetlb: Make huge_pte_offset()
thread-safe for pmd unshare") which addresses a rare race condition
related to PMD unsharing.

over to its sysfs interface. To support this, we'll temporarily be
printing warnings when people use the debugfs interface. See the series
"mm/damon: deprecate DAMON debugfs interface".
- Andrey Konovalov provided the accurately named "lib/stackdepot: fixes
and clean-ups" series.

Networking changes for 6.3.
Core
----
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used
to describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols
---------
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP
path manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF
---
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key
to better support decap on GRE tunnel devices not operating
in collect metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk
and bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols
by livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter
---------
- Remove the CLUSTERIP target. It has been marked as obsolete
for years, and we still have WARN splats wrt. races of
the out-of-band /proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to
the existing 'delete' commands, but do not return an error if
the referenced object (set, chain, rule...) did not exist.
Driver API
----------
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into multiple
files, drop some of the unnecessarily granular locks and factor out
common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless Extensions
for Wi-Fi 7 devices at all. Everyone should switch to using nl80211
interface instead.
- Improve the CAN bit timing configuration. Use extack to return error
messages directly to user space, update the SJW handling, including
the definition of a new default value that will benefit CAN-FD
controllers, by increasing their oscillator tolerance.

arm64 updates for 6.3:
- Support for arm64 SME 2 and 2.1. SME2 introduces a new 512-bit architectural register (ZT0, for the look-up table feature) that Linux needs to save/restore. - Include TPIDR2 in the signal context and add the corresponding kselftests. - Perf updates: Arm SPEv1.2 support, HiSilicon uncore PMU updates, ACPI support to the Marvell DDR and TAD PMU drivers, reset DTM_PMU_CONFIG (ARM CMN) at probe time. - Support for DYNAMIC_FTRACE_WITH_CALL_OPS on arm64. - Permit EFI boot with MMU and caches on. Instead of cleaning the entire loaded kernel image to the PoC and disabling the MMU and caches before branching to the kernel bare metal entry point, leave the MMU and caches enabled and rely on EFI's cacheable 1:1 mapping of all of system RAM to populate the initial page tables. - Expose the AArch32 (compat) ELF_HWCAP features to user in an arm64 kernel (the arm32 kernel only defines the values). - Harden the arm64 shadow call stack pointer handling: stash the shadow stack pointer in the task struct on interrupt, load it directly from this structure. - Signal handling cleanups to remove redundant validation of size information and avoid reading the same data from userspace twice. - Refactor the hwcap macros to make use of the automatically generated ID registers. It should make new hwcaps writing less error prone. - Further arm64 sysreg conversion and some fixes. - arm64 kselftest fixes and improvements. - Pointer authentication cleanups: don't sign leaf functions, unify asm-arch manipulation. - Pseudo-NMI code generation optimisations. - Minor fixes for SME and TPIDR2 handling. - Miscellaneous updates: ARCH_FORCE_MAX_ORDER is now selectable, replace strtobool() to kstrtobool() in the cpufeature.c code, apply dynamic shadow call stack in two passes, intercept pfn changes in set_pte_at() without the required break-before-make sequence, attempt to dump all instructions on unhandled kernel faults. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmP0/QsACgkQa9axLQDI XvG+gA/+JDVEH9wRzAIZvbp9hSuohPc48xgAmIMP1eiVB0/5qeRjYAJwS33H0rXS BPC2kj9IBy/eQeM9ICg0nFd0zYznSVacITqe6NrqeJ1F+ftS4rrHdfxd+J7kIoCs V2L8e+BJvmHdhmNV2qMAgJdGlfxfQBA7fv2cy52HKYcouoOh1AUVR/x+yXVXAsCd qJP3+dlUKccgm/oc5unEC1eZ49u8O+EoasqOyfG6K5udMgzhEX3K6imT9J3hw0WT UjstYkx5uGS/prUrRCQAX96VCHoZmzEDKtQuHkHvQXEYXsYPF3ldbR2CziNJnHe7 QfSkjJlt8HAtExA+BkwEe9i0MQO/2VF5qsa2e4fA6l7uqGu3LOtS/jJd23C9n9fR Id8aBMeN6S8+MjqRA9L2uf4t6e4ISEHoG9ZRdc4WOwloxEEiJoIeun+7bHdOSZLj AFdHFCz4NXiiwC0UP0xPDI2YeCLqt5np7HmnrUqwzRpVO8UUagiJD8TIpcBSjBN9 J68eidenHUW7/SlIeaMKE2lmo8AUEAJs9AorDSugF19/ThJcQdx7vT2UAZjeVB3j 1dbbwajnlDOk/w8PQC4thFp5/MDlfst0htS3WRwa+vgkweE2EAdTU4hUZ8qEP7FQ smhYtlT1xUSTYDTqoaG/U2OWR6/UU79wP0jgcOsHXTuyYrtPI/Q= =VmXL -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: - Support for arm64 SME 2 and 2.1.
