2025-02-13sched_ext: Fix the incorrect bpf_list kfunc API in common.bpf.h.Chuyi Zhou
Now BPF only supports bpf_list_push_{front,back}_impl kfunc, not bpf_list_ push_{front,back}. This patch fix this issue. Without this patch, if we use bpf_list kfunc in scx, the BPF verifier would complain: libbpf: extern (func ksym) 'bpf_list_push_back': not found in kernel or module BTFs libbpf: failed to load object 'scx_foo' libbpf: failed to load BPF skeleton 'scx_foo': -EINVAL With this patch, the bpf list kfunc will work as expected.

2025-02-12tools build: Fix a number of Wconversion warningsIan Rogers
There's some expressed interest in having the compiler flag -Wconversion detect at build time certain kinds of potential problems: https://lore.kernel.org/lkml/20250103182532.GB781381@e132581.arm.com/ As feature detection passes -Wconversion from CFLAGS when set, the feature detection compile tests need to not fail because of -Wconversion as the failure will be interpretted as a missing feature. Switch various types to avoid the -Wconversion issue, the exact meaning of the code is unimportant as it is typically looking for header file definitions.

2025-02-12perf sample: Make user_regs and intr_regs optionalIan Rogers
The struct dump_regs contains 512 bytes of cache_regs, meaning the two values in perf_sample contribute 1088 bytes of its total 1384 bytes size. Initializing this much memory has a cost reported by Tavian Barnes <tavianator@tavianator.com> as about 2.5% when running `perf script --itrace=i0`: https://lore.kernel.org/lkml/d841b97b3ad2ca8bcab07e4293375fb7c32dfce7.1736618095.git.tavianator@tavianator.com/ Adrian Hunter <adrian.hunter@intel.com> replied that the zero initialization was necessary and couldn't simply be removed. This patch aims to strike a middle ground of still zeroing the perf_sample, but removing 79% of its size by make user_regs and intr_regs optional pointers to zalloc-ed memory. To support the allocation accessors are created for user_regs and intr_regs. To support correct cleanup perf_sample__init and perf_sample__exit functions are created and added throughout the code base.

The --summary-mode option will select how to show the syscall summary at the end. By default, it'll show the summary for each thread and it's the same as if --summary-mode=thread is passed. The other option is to show total summary, which is --summary-mode=total.

2025-02-12KVM: selftests: Close VM's binary stats FD when releasing VMSean Christopherson
Close/free a VM's binary stats cache when the VM is released, not when the VM is fully freed. When a VM is re-created, e.g. for state save/restore tests, the stats FD and descriptor points at the old, defunct VM. The FD is still valid, in that the underlying stats file won't be freed until the FD is closed, but reading stats will always pull information from the old VM. Note, this is a benign bug in the current code base as none of the tests that recreate VMs use binary stats.
