Pull perf tools fixes from Arnaldo Carvalho de Melo: - Update more header copies with the kernel sources, including const.h, msr-index.h, arm64's cputype.h, kvm's, bits.h and unaligned.h - The return from 'write' isn't a pid, fix cut'n'paste error in 'perf trace' - Fix up the python binding build on architectures without HAVE_KVM_STAT_SUPPORT - Add some more bounds checks to augmented_raw_syscalls.bpf.c (used to collect syscall pointer arguments in 'perf trace') to make the resulting bytecode to pass the kernel BPF verifier, allowing us to go back accepting clang 12.0.1 as the minimum version required for compiling BPF sources - Add __NR_capget for x86 to fix a regression on running perf + intel PT (hw tracing) as non-root setting up the capabilities as described in https://www.kernel.org/doc/html/latest/admin-guide/perf-security.html - Fix missing syscalltbl in non-explicitly listed architectures, noticed on ARM 32-bit, that still needs a .tbl generator for the syscall id<->name tables, should be added for v6.13 - Handle 'perf test' failure when handling broken DWARF for ASM files * tag 'perf-tools-fixes-for-v6.12-2-2024-10-30' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools: perf cap: Add __NR_capget to arch/x86 unistd tools headers: Update the linux/unaligned.h copy with the kernel sources tools headers arm64: Sync arm64's cputype.h with the kernel sources tools headers: Synchronize {uapi/}linux/bits.h with the kernel sources tools arch x86: Sync the msr-index.h copy with the kernel sources perf python: Fix up the build on architectures without HAVE_KVM_STAT_SUPPORT perf test: Handle perftool-testsuite_probe failure due to broken DWARF tools headers UAPI: Sync kvm headers with the kernel sources perf trace: Fix non-listed archs in the syscalltbl routines perf build: Change the clang check back to 12.0.1 perf trace augmented_raw_syscalls: Add more checks to pass the verifier perf trace augmented_raw_syscalls: Add extra array index bounds checking to satisfy some BPF verifiers perf trace: The return from 'write' isn't a pid tools headers UAPI: Sync linux/const.h with the kernel headers

bpf: Add the missing BPF_LINK_TYPE invocation for sockmap

2024-10-24T17:17:12Z

There is an out-of-bounds read in bpf_link_show_fdinfo() for the sockmap link fd. Fix it by adding the missing BPF_LINK_TYPE invocation for sockmap link Also add comments for bpf_link_type to prevent missing updates in the future.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h
