git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Support usec resolution of TCP timestamps, enabled selectively by a route attribute. - Defer regular TCP ACK while processing socket backlog, try to send a cumulative ACK at the end. Increase single TCP flow performance on a 200Gbit NIC by 20% (100Gbit -> 120Gbit). - The Fair Queuing (FQ) packet scheduler: - add built-in 3 band prio / WRR scheduling - support bypass if the qdisc is mostly idle (5% speed up for TCP RR) - improve inactive flow reporting - optimize the layout of structures for better cache locality - Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern replacement for the old MD5 option. - Add more retransmission timeout (RTO) related statistics to TCP_INFO. - Support sending fragmented skbs over vsock sockets. - Make sure we send SIGPIPE for vsock sockets if socket was shutdown(). - Add sysctl for ignoring lower limit on lifetime in Router Advertisement PIO, based on an in-progress IETF draft. - Add sysctl to control activation of TCP ping-pong mode. - Add sysctl to make connection timeout in MPTCP configurable. - Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps limit the number of wakeups. - Support netlink GET for MDB (multicast forwarding), allowing user space to request a single MDB entry instead of dumping the entire table. - Support selective FDB flushing in the VXLAN tunnel driver. - Allow limiting learned FDB entries in bridges, prevent OOM attacks. - Allow controlling via configfs netconsole targets which were created via the kernel cmdline at boot, rather than via configfs at runtime. - Support multiple PTP timestamp event queue readers with different filters. - MCTP over I3C. BPF: - Add new veth-like netdevice where BPF program defines the logic of the xmit routine. It can operate in L3 and L2 mode. - Support exceptions - allow asserting conditions which should never be true but are hard for the verifier to infer. With some extra flexibility around handling of the exit / failure: https://lwn.net/Articles/938435/ - Add support for local per-cpu kptr, allow allocating and storing per-cpu objects in maps. Access to those objects operates on the value for the current CPU. This allows to deprecate local one-off implementations of per-CPU storage like BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps. - Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is for systemd to re-implement the LogNamespace feature which allows running multiple instances of systemd-journald to process the logs of different services. - Enable open-coded task_vma iteration, after maple tree conversion made it hard to directly walk VMAs in tracing programs. - Add open-coded task, css_task and css iterator support. One of the use cases is customizable OOM victim selection via BPF. - Allow source address selection with bpf_*_fib_lookup(). - Add ability to pin BPF timer to the current CPU. - Prevent creation of infinite loops by combining tail calls and fentry/fexit programs. - Add missed stats for kprobes to retrieve the number of missed kprobe executions and subsequent executions of BPF programs. - Inherit system settings for CPU security mitigations. - Add BPF v4 CPU instruction support for arm32 and s390x. Changes to common code: - overflow: add DEFINE_FLEX() for on-stack definition of structs with flexible array members. - Process doc update with more guidance for reviewers. Driver API: - Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy mutex in most places and remove a lot of smaller locks. - Create a common DPLL configuration API. Allow configuring and querying state of PLL circuits used for clock syntonization, in network time distribution. - Unify fragmented and full page allocation APIs in page pool code. Let drivers be ignorant of PAGE_SIZE. - Rework PHY state machine to avoid races with calls to phy_stop(). - Notify DSA drivers of MAC address changes on user ports, improve correctness of offloads which depend on matching port MAC addresses. - Allow antenna control on injected WiFi frames. - Reduce the number of variants of napi_schedule(). - Simplify error handling when composing devlink health messages. Misc: - A lot of KCSAN data race "fixes", from Eric. - A lot of __counted_by() annotations, from Kees. - A lot of strncpy -> strscpy and printf format fixes. - Replace master/slave terminology with conduit/user in DSA drivers. - Handful of KUnit tests for netdev and WiFi core. Removed: - AppleTalk COPS. - AppleTalk ipddp. - TI AR7 CPMAC Ethernet driver.

KVM x86 misc changes for 6.7: - Add CONFIG_KVM_MAX_NR_VCPUS to allow supporting up to 4096 vCPUs without forcing more common use cases to eat the extra memory overhead. - Add IBPB and SBPB virtualization support. - Fix a bug where restoring a vCPU snapshot that was taken within 1 second of creating the original vCPU would cause KVM to try to synchronize the vCPU's TSC and thus clobber the correct TSC being set by userspace. - Compute guest wall clock using a single TSC read to avoid generating an inaccurate time, e.g. if the vCPU is preempted between multiple TSC reads. - "Virtualize" HWCR.TscFreqSel to make Linux guests happy, which complain about a "Firmware Bug" if the bit isn't set for select F/M/S combos. - Don't apply side effects to Hyper-V's synthetic timer on writes from userspace to fix an issue where the auto-enable behavior can trigger spurious interrupts, i.e. do auto-enabling only for guest writes. - Remove an unnecessary kick of all vCPUs when synchronizing the dirty log without PML enabled. - Advertise "support" for non-serializing FS/GS base MSR writes as appropriate. - Use octal notation for file permissions through KVM x86. - Fix a handful of typo fixes and warts.

Pull nfsd updates from Chuck Lever: "This release completes the SunRPC thread scheduler work that was begun in v6.6. The scheduler can now find an svc thread to wake in constant time and without a list walk. Thanks again to Neil Brown for this overhaul. Lorenzo Bianconi contributed infrastructure for a netlink-based NFSD control plane. The long-term plan is to provide the same functionality as found in /proc/fs/nfsd, plus some interesting additions, and then migrate the NFSD user space utilities to netlink. A long series to overhaul NFSD's NFSv4 operation encoding was applied in this release. The goals are to bring this family of encoding functions in line with the matching NFSv4 decoding functions and with the NFSv2 and NFSv3 XDR functions, preparing the way for better memory safety and maintainability. A further improvement to NFSD's write delegation support was contributed by Dai Ngo. This adds a CB_GETATTR callback, enabling the server to retrieve cached size and mtime data from clients holding write delegations. If the server can retrieve this information, it does not have to recall the delegation in some cases. The usual panoply of bug fixes and minor improvements round out this release.

2023-10-27tools/testing/cxl: Slow down the mock firmware transferVishal Verma1-0/+1
The cxl-cli unit test for firmware update does operations like starting an asynchronous firmware update, making sure it is in progress, and attempting to cancel it. In some cases, such as with no or minimal dynamic debugging turned on, the firmware update completes too quickly, not allowing the test to have a chance to verify it was in progress. This caused a failure of the signature: expected fw_update_in_progress:true test/cxl-update-firmware.sh: failed at line 88 Fix this by adding a delay (~1.5 - 2 ms) to each firmware transfer request handled by the mocked interface.

2023-10-27cxl/region: Fix x1 root-decoder granularity calculationsJim Harris1-1/+1
Root decoder granularity must match value from CFWMS, which may not be the region's granularity for non-interleaved root decoders. So when calculating granularities for host bridge decoders, use the region's granularity instead of the root decoder's granularity to ensure the correct granularities are set for the host bridge decoders and any downstream switch decoders. Test configuration is 1 host bridge * 2 switches * 2 endpoints per switch. Region created with 2048 granularity using following command line: cxl create-region -m -d decoder0.0 -w 4 mem0 mem2 mem1 mem3 \ -g 2048 -s 2048M Use "cxl list -PDE | grep granularity" to get a view of the granularity set at each level of the topology.

The second input parameter of 'wait_rm_addr/sf $1 1' is misused. If it's 1, wait_rm_addr/sf will never break, and will loop ten times, then 'wait_rm_addr/sf' equals to 'sleep 1'. This delay time is too long, which can sometimes make the tests fail. A better way to use wait_rm_addr/sf is to use rm_addr/sf_count to obtain the current value, and then pass into wait_rm_addr/sf.
