This patchset is based on the 20230705-nolibc-series2 branch of nolibc repo [2], it must be applied after our v6 __sysret series [3] (argv0 exported there) and Thomas' chmod_net removal patchset [4] (the new chmod_argv0 is added at the same line of chmod_net, will conflict). This patchset assumes the chmod_net removal patchset will be applied at first, if not, the chmod_argv0 added alphabetically will not be applied. Since our new chmod_argv0 is exactly added to replace chmod_net, so, Willy, is it ok for you to at least apply the chmod_net removal patch [5] before this patchset? selftests/nolibc: drop test chmod_net This patchset is tested together with the v6 __sysret series [3]: arch/board | result ------------|------------ arm/vexpress-a9 | 142 test(s) passed, 1 skipped, 0 failed. arm/virt | 142 test(s) passed, 1 skipped, 0 failed. aarch64/virt | 142 test(s) passed, 1 skipped, 0 failed. ppc/g3beige | not supported ppc/ppce500 | not supported i386/pc | 142 test(s) passed, 1 skipped, 0 failed. x86_64/pc | 142 test(s) passed, 1 skipped, 0 failed. mipsel/malta | 142 test(s) passed, 1 skipped, 0 failed. loongarch64/virt | 142 test(s) passed, 1 skipped, 0 failed. riscv64/virt | 142 test(s) passed, 1 skipped, 0 failed. riscv32/virt | 0 test(s) passed, 0 skipped, 0 failed. s390x/s390-ccw-virtio | 142 test(s) passed, 1 skipped, 0 failed.
