Wire up the following system calls for all architectures: * landlock_get_features(2) * landlock_create_ruleset(2) * landlock_add_rule(2) * landlock_enforce_ruleset(2) Signed-off-by: Mickaël Salaün <mic@xxxxxxxxxxx> Cc: Arnd Bergmann <arnd@xxxxxxxx> Cc: James Morris <jmorris@xxxxxxxxx> Cc: Jann Horn <jannh@xxxxxxxxxx> Cc: Kees Cook <keescook@xxxxxxxxxxxx> Cc: Serge E. Hallyn <serge@xxxxxxxxxx> --- Changes since v19: * Increase syscall numbers by 4 to leave space for new ones (in linux-next): watch_mount(2), watch_sb(2), fsinfo(2) and process_madvise(2) (requested by Arnd Bergmann). * Replace the previous multiplexor landlock(2) with 4 syscalls: landlock_get_features(2), landlock_create_ruleset(2), landlock_add_rule(2) and landlock_enforce_ruleset(2). Changes since v18: * Increase the syscall number because of the new faccessat2(2). Changes since v14: * Add all architectures. Changes since v13: * New implementation. --- arch/alpha/kernel/syscalls/syscall.tbl | 4 ++++ arch/arm/tools/syscall.tbl | 4 ++++ arch/arm64/include/asm/unistd.h | 2 +-
