2024-05-23testing: net-drv: use stats64 for testingJoe Damato
Testing a network device that has large numbers of bytes/packets may overflow. Using stats64 when comparing fixes this problem. I tripped on this while iterating on a qstats patch for mlx5. See below for confirmation without my added code that this is a bug. Before this patch (with added debugging output): $ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py KTAP version 1 1..4 ok 1 stats.check_pause ok 2 stats.check_fec rstat: 481708634 qstat: 666201639514 key: tx-bytes not ok 3 stats.pkt_byte_sum ok 4 stats.qstat_by_ifindex Note the huge delta above ^^^ in the rtnl vs qstats. After this patch: $ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py KTAP version 1 1..4 ok 1 stats.check_pause ok 2 stats.check_fec ok 3 stats.pkt_byte_sum ok 4 stats.qstat_by_ifindex It looks like rtnl_fill_stats in net/core/rtnetlink.c will attempt to copy the 64bit stats into a 32bit structure which is probably why this behavior is occurring. To show this is happening, you can get the underlying stats that the stats.py test uses like this: $ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \ --do getlink --json '{"ifi-index": 7}' And examine the output (heavily snipped to show relevant fields): 'stats': { 'multicast': 3739197, 'rx-bytes': 1201525399, 'rx-packets': 56807158, 'tx-bytes': 492404458, 'tx-packets': 1200285371, 'stats64': { 'multicast': 3739197, 'rx-bytes': 35561263767, 'rx-packets': 56807158, 'tx-bytes': 666212335338, 'tx-packets': 1200285371, The stats.py test prior to this patch was using the 'stats' structure above, which matches the failure output on my system. Comparing side by side, rx-bytes and tx-bytes, and getting ethtool -S output: rx-bytes stats: 1201525399 rx-bytes stats64: 35561263767 rx-bytes ethtool: 36203402638 tx-bytes stats: 492404458 tx-bytes stats64: 666212335338 tx-bytes ethtool: 666215360113 Note that the above was taken from a system with an mlx5 NIC, which only exposes ndo_get_stats64. Based on the ethtool output and qstat output, it appears that stats.py should be updated to use the 'stats64' structure for accurate comparisons when packet/byte counters get very large. To confirm that this was not related to the qstats code I was iterating on, I booted a kernel without my driver changes and re-ran the test which shows the qstats are skipped (as they don't exist for mlx5): NETIF=eth0 tools/testing/selftests/drivers/net/stats.py KTAP version 1 1..4 ok 1 stats.check_pause ok 2 stats.check_fec ok 3 stats.pkt_byte_sum # SKIP qstats not supported by the device ok 4 stats.qstat_by_ifindex # SKIP No ifindex supports qstats But, fetching the stats using the CLI $ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \ --do getlink --json '{"ifi-index": 7}' Shows the same issue (heavily snipped for relevant fields only): 'stats': { 'multicast': 105489, 'rx-bytes': 530879526, 'rx-packets': 751415, 'tx-bytes': 2510191396, 'tx-packets': 27700323, 'stats64': { 'multicast': 105489, 'rx-bytes': 530879526, 'rx-packets': 751415, 'tx-bytes': 15395093284, 'tx-packets': 27700323, Comparing side by side with ethtool -S on the unmodified mlx5 driver: tx-bytes stats: 2510191396 tx-bytes stats64: 15395093284 tx-bytes ethtool: 17718435810 Fixes: f0e6c86e4bab ("testing: net-drv: add a driver test for stats reporting") Signed-off-by: Joe Damato <jdamato@fastly.com> Link: https://lore.kernel.org/r/20240520235850.190041-1-jdamato@fastly.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2024-05-21selftests/net: use tc rule to filter the na packetHangbin Liu
Test arp_ndisc_untracked_subnets use tcpdump to filter the unsolicited and untracked na messages. It set -e before calling tcpdump. But if tcpdump filters 0 packet, it will return none zero, and cause the script to exit. Instead of using slow tcpdump to capture packets, let's using tc rule to filter out the na message. At the same time, fix function setup_v6 which only needs one parameter. Move all the related helpers from forwarding lib.sh to net lib.sh.

2024-05-19Revert "selftests/harness: remove use of LINE_MAX"Tao Su
Patch series "Selftests: Fix compilation warnings due to missing _GNU_SOURCE definition", v2. Since kselftest_harness.h introduces asprintf()[1], many selftests have compilation warnings or errors due to missing _GNU_SOURCE definitions. The issue stems from a lack of a LINE_MAX definition in Android (see commit 38c957f07038), which is the reason why asprintf() was introduced. We tried adding _GNU_SOURCE definitions to more selftests to fix, but asprintf() may continue to cause problems, and since it is quite late in the 6.9 cycle, we would like to revert 809216233555 first to provide testing for forks[2].

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing user-event updates from Steven Rostedt: - Minor update to the user_events interface The ABI of creating a user event states that the fields are separated by semicolons, and spaces should be ignored. But the parsing expected at least one space to be there (which was incorrect). Fix the reading of the string to handle fields separated by semicolons but no space between them. This does extend the API sightly as now "field;field" will now be parsed and not cause an error. But it should not cause any regressions as no logic should expect it to fail. Note, that the logic that parses the event fields to create the trace_event works with no spaces after the semi-colon. It is the logic that tests against existing events that is inconsistent. This causes registering an event without using spaces to succeed if it doesn't exist, but makes the same call that tries to register to the same event, but doesn't use spaces, fail. * tag 'trace-user-events-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: selftests/user_events: Add non-spacing separator check tracing/user_events: Fix non-spaced field matching

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. 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" * tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Add cast to unsigned long addr passed to virt_to_page() ring-buffer: Have mmapped ring buffer keep track of missed events ring-buffer/selftest: Add ring-buffer mapping test Documentation: tracing: Add ring-buffer mapping tracing: Allow user-space mapping of the ring-buffer ring-buffer: Introducing ring-buffer mapping functions ring-buffer: Allocate sub-buffers with __GFP_COMP

Pull KVM updates from Paolo Bonzini: "ARM: - Move a lot of state that was previously stored on a per vcpu basis into a per-CPU area, because it is only pertinent to the host while the vcpu is loaded. This results in better state tracking, and a smaller vcpu structure. - Add full handling of the ERET/ERETAA/ERETAB instructions in nested virtualisation. The last two instructions also require emulating part of the pointer authentication extension. As a result, the trap handling of pointer authentication has been greatly simplified. - Turn the global (and not very scalable) LPI translation cache into a per-ITS, scalable cache, making non directly injected LPIs much cheaper to make visible to the vcpu. - A batch of pKVM patches, mostly fixes and cleanups, as the upstreaming process seems to be resuming. Fingers crossed! - Allocate PPIs and SGIs outside of the vcpu structure, allowing for smaller EL2 mapping and some flexibility in implementing more or less than 32 private IRQs. - Purge stale mpidr_data if a vcpu is created after the MPIDR map has been created. - Preserve vcpu-specific ID registers across a vcpu reset. - Various minor cleanups and improvements. LoongArch: - Add ParaVirt IPI support - Add software breakpoint support - Add mmio trace events support RISC-V: - Support guest breakpoints using ebreak - Introduce per-VCPU mp_state_lock and reset_cntx_lock - Virtualize SBI PMU snapshot and counter overflow interrupts - New selftests for SBI PMU and Guest ebreak - Some preparatory work for both TDX and SNP page fault handling. This also cleans up the page fault path, so that the priorities of various kinds of fauls (private page, no memory, write to read-only slot, etc.) are easier to follow. x86: - Minimize amount of time that shadow PTEs remain in the special REMOVED_SPTE state. This is a state where the mmu_lock is held for reading but concurrent accesses to the PTE have to spin; shortening its use allows other vCPUs to repopulate the zapped region while the zapper finishes tearing down the old, defunct page tables. - Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID field, which is defined by hardware but left for software use. This lets KVM communicate its inability to map GPAs that set bits 51:48 on hosts without 5-level nested page tables. Guest firmware is expected to use the information when mapping BARs; this avoids that they end up at a legal, but unmappable, GPA. - Fixed a bug where KVM would not reject accesses to MSR that aren't supposed to exist given the vCPU model and/or KVM configuration. - As usual, a bunch of code cleanups. x86 (AMD): - Implement a new and improved API to initialize SEV and SEV-ES VMs, which will also be extendable to SEV-SNP. The new API specifies the desired encryption in KVM_CREATE_VM and then separately initializes the VM. The new API also allows customizing the desired set of VMSA features; the features affect the measurement of the VM's initial state, and therefore enabling them cannot be done tout court by the hypervisor. While at it, the new API includes two bugfixes that couldn't be applied to the old one without a flag day in userspace or without affecting the initial measurement. When a SEV-ES VM is created with the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are rejected once the VMSA has been encrypted. Also, the FPU and AVX state will be synchronized and encrypted too. - Support for GHCB version 2 as applicable to SEV-ES guests. This, once more, is only accessible when using the new KVM_SEV_INIT2 flow for initialization of SEV-ES VMs. x86 (Intel): - An initial bunch of prerequisite patches for Intel TDX were merged. They generally don't do anything interesting. The only somewhat user visible change is a new debugging mode that checks that KVM's MMU never triggers a #VE virtualization exception in the guest. - Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig VM-Exit to L1, as per the SDM. Generic: - Use vfree() instead of kvfree() for allocations that always use vcalloc() or __vcalloc(). - Remove .change_pte() MMU notifier - the changes to non-KVM code are small and Andrew Morton asked that I also take those through the KVM tree. The callback was only ever implemented by KVM (which was also the original user of MMU notifiers) but it had been nonfunctional ever since calls to set_pte_at_notify were wrapped with invalidate_range_start and invalidate_range_end... in 2012. Selftests: - Enhance the demand paging test to allow for better reporting and stressing of UFFD performance. - Convert the steal time test to generate TAP-friendly output. - Fix a flaky false positive in the xen_shinfo_test due to comparing elapsed time across two different clock domains. - Skip the MONITOR/MWAIT test if the host doesn't actually support MWAIT. - Avoid unnecessary use of "sudo" in the NX hugepage test wrapper shell script, to play nice with running in a minimal userspace environment. - Allow skipping the RSEQ test's sanity check that the vCPU was able to complete a reasonable number of KVM_RUNs, as the assert can fail on a completely valid setup. If the test is run on a large-ish system that is otherwise idle, and the test isn't affined to a low-ish number of CPUs, the vCPU task can be repeatedly migrated to CPUs that are in deep sleep states, which results in the vCPU having very little net runtime before the next migration due to high wakeup latencies. - Define _GNU_SOURCE for all selftests to fix a warning that was introduced by a change to kselftest_harness.h late in the 6.9 cycle, and because forcing every test to #define _GNU_SOURCE is painful. - Provide a global pseudo-RNG instance for all tests, so that library code can generate random, but determinstic numbers. - Use the global pRNG to randomly force emulation of select writes from guest code on x86, e.g. to help validate KVM's emulation of locked accesses. - Allocate and initialize x86's GDT, IDT, TSS, segments, and default exception handlers at VM creation, instead of forcing tests to manually trigger the related setup.

Increase the membership interval from 3 to 5 seconds to make room for the setup validation and 2 seconds of sleep.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "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 - support XDP metadata - make page pool allocations more NUMA aware - Intel (100G, ice, idpf): - extract datapath code common among Intel drivers into a library - use fewer resources in switchdev by sharing queues with the PF - add PFCP filter support - add Ethernet filter support - use a spinlock instead of HW lock in PTP clock ops - support 5 layer Tx scheduler topology - nVidia/Mellanox: - 800G link modes and 100G SerDes speeds - per-queue IRQ coalescing configuration - Marvell Octeon: - support offloading TC packet mark action - Ethernet NICs consumer, embedded and virtual: - stop lying about skb->truesize in USB Ethernet drivers, it messes up TCP memory calculations - Google cloud vNIC: - support changing ring size via ethtool - support ring reset using the queue control API - VirtIO net: - expose flow hash from RSS to XDP - per-queue statistics - add selftests - Synopsys (stmmac): - support controllers which require an RX clock signal from the MII bus to perform their hardware initialization - TI: - icssg_prueth: support ICSSG-based Ethernet on AM65x SR1.0 devices - icssg_prueth: add SW TX / RX Coalescing based on hrtimers - cpsw: minimal XDP support - Renesas (ravb): - support describing the MDIO bus - Realtek (r8169): - add support for RTL8168M - Microchip Sparx5: - matchall and flower actions mirred and redirect - Ethernet switches: - nVidia/Mellanox: - improve events processing performance - Marvell: - add support for MV88E6250 family internal PHYs - Microchip: - add DCB and DSCP mapping support for KSZ switches - vsc73xx: convert to PHYLINK - Realtek: - rtl8226b/rtl8221b: add C45 instances and SerDes switching - Many driver changes related to PHYLIB and PHYLINK deprecated API cleanup - Ethernet PHYs: - Add a new driver for Airoha EN8811H 2.5 Gigabit PHY. - micrel: lan8814: add support for PPS out and external timestamp trigger - WiFi: - Disable Wireless Extensions (WEXT) in all Wi-Fi 7 devices drivers.

ACPI: - Support for the Firmware ACPI Control Structure (FACS) signature feature which is used to reboot out of hibernation on some systems Kbuild: - Support for building Flat Image Tree (FIT) images, where the kernel Image is compressed alongside a set of devicetree blobs Memory management: - Optimisation of our early page-table manipulation for creation of the linear mapping - Support for userfaultfd write protection, which brings along some nice cleanups to our handling of invalid but present ptes - Extend our use of range TLBI invalidation at EL1 Perf and PMUs: - Ensure that the 'pmu->parent' pointer is correctly initialised by PMU drivers - Avoid allocating 'cpumask_t' types on the stack in some PMU drivers - Fix parsing of the CPU PMU "version" field in assembly code, as it doesn't follow the usual architectural rules - Add best-effort unwinding support for USER_STACKTRACE - Minor driver fixes and cleanups Selftests: - Minor cleanups to the arm64 selftests (missing NULL check, unused variable) Miscellaneous: - Add a command-line alias for disabling 32-bit application support - Add part number for Neoverse-V2 CPUs - Minor fixes and cleanups" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (64 commits) arm64/mm: Fix pud_user_accessible_page() for PGTABLE_LEVELS <= 2 arm64/mm: Add uffd write-protect support arm64/mm: Move PTE_PRESENT_INVALID to overlay PTE_NG arm64/mm: Remove PTE_PROT_NONE bit arm64/mm: generalize PMD_PRESENT_INVALID for all levels arm64: simplify arch_static_branch/_jump function arm64: Add USER_STACKTRACE support arm64: Add the arm64.no32bit_el0 command line option drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset() drivers/perf: hisi: hns3: Fix out-of-bound access when valid event group drivers/perf: hisi_pcie: Fix out-of-bound access when valid event group kselftest: arm64: Add a null pointer check arm64: defer clearing DAIF.D arm64: assembler: update stale comment for disable_step_tsk arm64/sysreg: Update PIE permission encodings kselftest/arm64: Remove unused parameters in abi test perf/arm-spe: Assign parents for event_source device perf/arm-smmuv3: Assign parents for event_source device perf/arm-dsu: Assign parents for event_source device perf/arm-dmc620: Assign parents for event_source device ...

Some versions of conntrack(8) default to ipv4-only, so this needs to request ipv6 explicitly, like all other spots already do.
