Stop. The problem is that the asm-generic header only exists for the uapi variant, but arch/um has no uapi headers and instead uses the x86 userspace API.

Five years later, we still have a few architectures left that are missing clone3(), and the macro keeps getting in the way as it's fundamentally different from all the other __ARCH_WANT_SYS_* macros that are meant to provide backwards-compatibility with applications using older syscalls that are no longer provided by default. Address this by reversing the polarity of the macro, adding an __ARCH_BROKEN_SYS_CLONE3 macro to all architectures that don't already provide the syscall, and remove __ARCH_WANT_SYS_CLONE3 from all the other ones.

This for some reason includes the deprecated sys_sysfs() syscall that was presumably added by accident. The time32, renameat, stat64 and rlimit entries in the syscall_abis_32 entry are for system calls that were part of the generic ABI when arch/arc got added but are no longer enabled by default for new architectures. Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this.

I used a semi-automated text replacement method to do the conversion, and then used 'vimdiff' to synchronize the whitespace and the (unused) names of the non-compat syscalls with the arm version. There are two differences between the generated syscalls names and the old version: - the old asm/unistd32.h contained only a __NR_sync_file_range2 entry, while the arm32 version also defines __NR_arm_sync_file_range with the same number. I added this duplicate back in asm/unistd32.h. - __NR__sysctl was removed from the arm64 file a while ago, but all the tables still contain it. This should probably get removed everywhere but I added it here for consistency. On top of that, the arm64 version does not contain any references to the 32-bit OABI syscalls that are not supported by arm64. If we ever want to share the file between arm32 and arm64, it would not be hard to add support for both in one file.

Arnd Bergmann Date: Thu, 4 Jul 2024 14:33:34 +0200 Subject: arm64: generate 64-bit syscall.tbl Change the asm/unistd.h header for arm64 to no longer include asm-generic/unistd.h itself, but instead generate both the asm/unistd.h contents and the list of entry points using the syscall.tbl scripts that we use on most other architectures. Once his is done for the remaining architectures, the generic unistd.h header can be removed and the generated tbl file put in its place. The Makefile changes are more complex than they should be, I need a little help to improve those. Ideally this should be done in an architecture-independent way as well.

The time32, stat64 and rlimit entries in the syscall_abis_32 line are for system calls that were part of the generic ABI when arch/csky got added but are no longer enabled by default for new architectures. Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this.

Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this. When asm/syscalls.h is included in kernel/fork.c for the purpose of type checking, the redirection macros cause problems. Move these so only the references get redirected.

The newstat and rlimit entries in the syscall_abis_64 line are for system calls that were part of the generic ABI when riscv64 got added but are no longer enabled by default for new architectures. Both riscv32 and riscv64 also implement memfd_secret, which is optional for all architectures. Unlike all the other 32-bit architectures, the time32 and stat64 sets of syscalls are not enabled on riscv32. Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this.
