| H A D | seccomp.h | 6baaade1 Wed Jan 11 21:55:28 CST 2023 Michael Schmitz <schmitzmic@gmail.com> m68k: Add kernel seccomp support
Add secure_computing() call to syscall_trace_enter to actually
filter system calls.
Add necessary arch Kconfig options, define TIF_SECCOMP trace
flag and provide basic seccomp filter support in asm/syscall.h
syscall_get_nr currently uses the syscall nr stored in orig_d0
because we change d0 to a default return code before starting a
syscall trace. This may be inconsistent with syscall_rollback
copying orig_d0 to d0 (which we never check upon return from
trace). We use d0 for the return code from syscall_trace_enter
in entry.S currently, and could perhaps expand that to store
a new syscall number returned by the seccomp filter before
executing the syscall. This clearly needs some discussion.
seccomp_bpf self test on ARAnyM passes 81 out of 94 tests.
