Rust fixes for v7.0-rc1
Toolchain and infrastructure:
- Pass '-Zunstable-options' flag required by the future Rust 1.95.0.
- Fix 'objtool' warning for Rust 1.84.0.
'kernel' crate:
- 'irq' module: add missing bound detected by the future Rust 1.95.0.
- 'list' module: add missing 'unsafe' blocks and placeholder safety
comments to macros (an issue for future callers within the crate).
'pin-init' crate:
- Clean Clippy warning that changed behavior in the future Rust 1.95.0.

tools/sched_ext: fix getopt not re-parsed on restart
After goto restart, optind retains its advanced position from the previous getopt loop, causing getopt() to immediately return -1. This silently drops all command-line options on the restarted skeleton. Reset optind to 1 at the restart label so options are re-parsed. Affected schedulers: scx_simple, scx_central, scx_flatcg, scx_pair, scx_sdt, scx_cpu0. Signed-off-by: David Carlier <devnexen@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org> |

tools/sched_ext: scx_userland: fix data races on shared counters
The stats thread reads nr_vruntime_enqueues, nr_vruntime_dispatches, nr_vruntime_failed, and nr_curr_enqueued concurrently with the main thread writing them, with no synchronization. Use __atomic builtins with relaxed ordering for all accesses to these counters to eliminate the data races. Only display accuracy is affected, not scheduling correctness.

libbpf: Remove extern declaration of bpf_stream_vprintk()
An issue was reported that building BPF program which includes both vmlinux.h and bpf_helpers.h from libbpf fails due to conflicting declarations of bpf_stream_vprintk().

selftests: tc_actions: don't dump 2MB of \0 to stdout
Since we started running selftests in NIPA we have been seeing
tc_actions.sh generate a soft lockup warning on ~20% of the runs.
On the pre-netdev foundation setup it was actually a missed irq
splat from the console. Now it's either that or a lockup.
I initially suspected a socket locking issue since the test
is exercising local loopback with act_mirred.
After hours of staring at this I noticed in strace that ncat
when -o $file is specified _both_ saves the output to the file
and still prints it to stdout. Because the file being sent
is constructed with:
dd conv=sparse status=none if=/dev/zero bs=1M count=2 of=$mirred
^^^^^^^^^
the data printed is all \0. Most terminals don't display nul
characters (and neither does vng output capture save them).
But QEMU's serial console still has to poke them thru which
is very slow and causes the lockup (if the file is >600kB).
Replace the '-o $file' with '> $file'. This speeds the test up
from 2m20s to 18s on debug kernels, and prevents the warnings.

selftests: forwarding: fix pedit tests failure with br_netfilter enabled
The tests use the tc pedit action to modify the IPv4 source address
("pedit ex munge ip src set"), but the IP header checksum is not
recalculated after the modification. As a result, the modified packet
fails sanity checks in br_netfilter after bridging and is dropped,
which causes the test to fail.
Fix this by ensuring net.bridge.bridge-nf-call-iptables is set to 0
during the test execution. This prevents the bridge from passing
L2 traffic to netfilter, bypassing the checksum validation that
causes the test failure.

selftests: forwarding: vxlan_bridge_1d_ipv6: fix test failure with br_netfilter enabled
The test generates VXLAN traffic using mausezahn, where the encapsulated
inner IPv6 packet has an incorrect payload length set in the IPv6 header.
After VXLAN decapsulation, such packets do not pass sanity checks in
br_netfilter and are dropped, which causes the test to fail.
Fix this by setting the correct IPv6 payload length for the encapsulated
packet generated by mausezahn, so that the packet is accepted
by br_netfilter.

selftests: drv-net: add HDS payload sweep test for devmem TCP
Add check_rx_hds test that verifies header/data split works across payload sizes. The test sweeps payload sizes from 1 byte to 8KB, if any data propagates up to userspace as SCM_DEVMEM_LINEAR, then the test fails. This shows that regardless of payload size, ncdevmem's configuration of hds-thresh to 0 is respected. Add -L (--fail-on-linear) flag to ncdevmem that causes the receiver to fail if any SCM_DEVMEM_LINEAR cmsg is received. Use socat option for fixed block sizing and tcp nodelay to disable nagle's algo to avoid buffering.

Note that this changes the bootconfig formatting but this should not fall under the don't break user space rule as users of bootconfig is for booting the kernel and not about applications running in the kernel's user space. - Update the tests for bootconfig parser to ensure the good examples to be parsed correctly by comparing the expected results. -----BEGIN PGP SIGNATURE----- iQFPBAABCgA5FiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmmPs+sbHG1hc2FtaS5o aXJhbWF0c3VAZ21haWwuY29tAAoJENv7B78FKz8bG60H/1GuYXlEbJrfM2G1moC5 c9HLkNON7xspEDWfT8lHk+T+4l7xj/Oriwl9Kkv/0F/P7NzIYZaSiHoht0TqrL6c /BR3pgHVayp4H/woaDZdo9KDCMFuxW0ukrbUriz/taMJn4+b7krScGoIM4sl1e02 cQVYbJxP9x5oEhgrQEOBUHnYSaEcB7qBclIUCQOl3UV9krTZpKOsLe3tNjcj0JrZ ACmSvP4oGKNIz+IarNmlV0m5enJk/pZLIpovbbrfm1vV4lxDWTCbSF2Q/dmpY43k ZIhjgjSES5bS5PSl7aQJW7j2itCUHDu7kYz+i8ifjqMnEcJkE9PqqsdJAhq1J63i M6w= =t5PQ -----END PGP SIGNATURE----- Merge tag 'bootconfig-v7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull bootconfig updates from Masami Hiramatsu: - Update the bootconfig parser to stop searching for a value when it encounters a newline character - Update the tests for bootconfig parser to ensure the good examples to be parsed correctly by comparing the expected results * tag 'bootconfig-v7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: bootconfig: Check the parsed output of the good examples bootconfig: Terminate value search if it hits a newline |

libbpf: Fix invalid write loop logic in bpf_linker__add_buf()
Fix bpf_linker__add_buf()'s logic of copying data from memory buffer into
memfd. In the event of short write not writing entire buf_sz bytes into memfd
file, we'll append bytes from the beginning of buf *again* (corrupting ELF
file contents) instead of correctly appending the rest of not-yet-read buf
contents.

selftests: netconsole: Increase port listening timeout
wait_for_port() can wait up to 2 seconds with the sleep and the polling
in wait_local_port_listen() combined. So, in netcons_basic.sh, the socat
process could die before the test writes to the netconsole.
Increase the timeout to 3 seconds to make netcons_basic.sh pass
consistently.

tools/power turbostat: Favor cpu# over core#
Turbostat collects statistics and outputs results in "topology order", which means it prioritizes the core# over the cpu#. The strategy is to minimize wakesups to a core -- which is important when measuring an idle system. But core order is problematic, because Linux core#'s are physical (within each package), and thus subject to APIC-id scrambling that may be done by the hardware or the BIOS. As a result users may be are faced with rows in a confusing order: sudo turbostat -q --show topology,Busy%,CPU%c6,UncMHz sleep 1 Core CPU Busy% CPU%c6 UncMHz - - 1.25 72.18 3400 0 4 7.74 0.00 1 5 1.77 88.59 2 6 0.48 96.73 3 7 0.21 98.34 4 8 0.14 96.85 5 9 0.26 97.55 6 10 0.44 97.24 7 11 0.12 96.18 8 0 5.41 0.31 3400 8 1 0.19 12 2 0.41 0.22 12 3 0.08 32 12 0.04 99.21 33 13 0.25 94.92 Abandon the legacy "core# topology order" in favor of simply ordering by cpu#, with a special case to handle HT siblings that may not have adjacent cpu#'s. sudo ./turbostat -q --show topology,Busy%,CPU%c6,UncMHz sleep 1 1.003001 sec Core CPU Busy% CPU%c6 UncMHz - - 1.38 80.55 1600 8 0 10.94 0.00 1600 8 1 0.53 12 2 2.90 0.45 12 3 0.11 0 4 1.96 91.20 1 5 0.97 96.40 2 6 0.24 94.72 3 7 0.31 98.01 4 8 0.20 98.20 5 9 0.62 96.00 6 10 0.06 98.15 7 11 0.12 99.31 32 12 0.04 99.07 33 13 0.27 95.09 The result is that cpu#'s now take precedence over core#'s.

Loongarch:
- Add more CPUCFG mask bits. - Improve feature detection. - Add lazy load support for FPU and binary translation (LBT) register state. - Fix return value for memory reads from and writes to in-kernel devices. - Add support for detecting preemption from within a guest. - Add KVM steal time test case to tools/selftests. ARM: - Add support for FEAT_IDST, allowing ID registers that are not implemented to be reported as a normal trap rather than as an UNDEF exception. - Add sanitisation of the VTCR_EL2 register, fixing a number of UXN/PXN/XN bugs in the process. - Full handling of RESx bits, instead of only RES0, and resulting in SCTLR_EL2 being added to the list of sanitised registers. - More pKVM fixes for features that are not supposed to be exposed to guests. - Make sure that MTE being disabled on the pKVM host doesn't give it the ability to attack the hypervisor. - Allow pKVM's host stage-2 mappings to use the Force Write Back version of the memory attributes by using the "pass-through' encoding. - Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the guest. - Preliminary work for guest GICv5 support. - A bunch of debugfs fixes, removing pointless custom iterators stored in guest data structures. - A small set of FPSIMD cleanups. - Selftest fixes addressing the incorrect alignment of page allocation. - Other assorted low-impact fixes and spelling fixes. RISC-V: - Fixes for issues discoverd by KVM API fuzzing in kvm_riscv_aia_imsic_has_attr(), kvm_riscv_aia_imsic_rw_attr(), and kvm_riscv_vcpu_aia_imsic_update() - Allow Zalasr, Zilsd and Zclsd extensions for Guest/VM - Transparent huge page support for hypervisor page tables - Adjust the number of available guest irq files based on MMIO register sizes found in the device tree or the ACPI tables - Add RISC-V specific paging modes to KVM selftests - Detect paging mode at runtime for selftests s390: - Performance improvement for vSIE (aka nested virtualization) - Completely new memory management. s390 was a special snowflake that enlisted help from the architecture's page table management to build hypervisor page tables, in particular enabling sharing the last level of page tables. This however was a lot of code (~3K lines) in order to support KVM, and also blocked several features. The biggest advantages is that the page size of userspace is completely independent of the page size used by the guest: userspace can mix normal pages, THPs and hugetlbfs as it sees fit, and in fact transparent hugepages were not possible before. It's also now possible to have nested guests and guests with huge pages running on the same host. - Maintainership change for s390 vfio-pci - Small quality of life improvement for protected guests x86: - Add support for giving the guest full ownership of PMU hardware (contexted switched around the fastpath run loop) and allowing direct access to data MSRs and PMCs (restricted by the vPMU model). KVM still intercepts access to control registers, e.g. to enforce event filtering and to prevent the guest from profiling sensitive host state. This is more accurate, since it has no risk of contention and thus dropped events, and also has significantly less overhead. For more information, see the commit message for merge commit |

selftests/sched_ext: Fix rt_stall flaky failure
The rt_stall test measures the runtime ratio between an EXT and an RT
task pinned to the same CPU, verifying that the deadline server prevents
RT tasks from starving SCHED_EXT tasks. It expects the EXT task to get
at least 4% of CPU time.
The test is flaky because sched_stress_test() calls sleep(RUN_TIME)
immediately after fork(), without waiting for the RT child to complete
its setup (set_affinity + set_sched). If the RT child experiences
scheduling latency before completing setup, that delay eats into the
measurement window: the RT child runs for less than RUN_TIME seconds,
and the EXT task's measured ratio drops below the 4% threshold.
For example, in the failing CI run [1]:
EXT=0.140s RT=4.750s total=4.890s (expected ~5.0s)
ratio=2.86% < 4% → FAIL
The 110ms gap (5.0 - 4.89) corresponds to the RT child's setup time
being counted inside the measurement window, during which fewer
deadline server ticks fire for the EXT task.
Fix by using pipes to synchronize: each child signals the parent after
completing its setup, and the parent waits for both signals before
starting sleep(RUN_TIME). This ensures the measurement window only
counts time when both tasks are fully configured and competing.
