Hi all, this series first cleans up the exec code and then adds proper kernel_execveat and kernel_wait callers instead of relying on the fact that the early init code and kernel threads implicitly run with the address limit set to KERNEL_DS. Note that the cleanup removes the compat execve(at) handlers entirely, as we can handle the compat difference very nicely in a unified codebase. x32 needs two hacky #defines for that for now, although those can go away if the x32 syscall rework from Brian gets merged. Changes since v1: - remove a pointless ifdef from get_user_arg_ptr - remove the need for a compat syscall handler for x32 Diffstat: arch/arm64/include/asm/unistd32.h | 4 arch/mips/kernel/syscalls/syscall_n32.tbl | 4 arch/mips/kernel/syscalls/syscall_o32.tbl | 4 arch/parisc/kernel/syscalls/syscall.tbl | 4 arch/powerpc/kernel/syscalls/syscall.tbl | 4 arch/s390/kernel/syscalls/syscall.tbl | 4 arch/sparc/kernel/syscalls.S | 4 arch/x86/entry/syscall_x32.c | 7 arch/x86/entry/syscalls/syscall_32.tbl | 4 arch/x86/entry/syscalls/syscall_64.tbl | 4 fs/exec.c | 248 ++++++++------------- include/linux/binfmts.h | 10 include/linux/compat.h | 7 include/linux/sched/task.h | 1 include/uapi/asm-generic/unistd.h | 4 init/main.c | 5 kernel/exit.c | 16 + kernel/umh.c | 43 --- tools/include/uapi/asm-generic/unistd.h | 4 tools/perf/arch/powerpc/entry/syscalls/syscall.tbl | 4 tools/perf/arch/s390/entry/syscalls/syscall.tbl | 4 tools/perf/arch/x86/entry/syscalls/syscall_64.tbl | 4 22 files changed, 170 insertions(+), 223 deletions(-)
