Hi Heiko,
[Added s390 mail list to recipients.]
Post by Heiko CarstensPost by Yury NorovThe problem that makes us to use wrappers is that some compat
architectures allows user code to access top halves of registers.
This is not a problem for syscalls that are already handled by compat
code, or for that who has types of the same size in kernel and
userspace. In case of lp64/ilp32 the problem is in pointer types, long,
unsigned long.
S390 folks already have the solution for it. In this patch,
it is turned to be general, as arm64/ilp32 needs it too.
Build-tested on s390.
If you want to make this generic then I think the footprint of the compat
[...]
Post by Heiko CarstensPost by Yury Norov+asmlinkage long compat_sys_creat(const char __user *pathname, umode_t mode);
+asmlinkage long compat_sys_link(const char __user *oldname,
+ const char __user *newname);
+asmlinkage long compat_sys_chdir(const char __user *filename);
+asmlinkage long compat_sys_mknod(const char __user *filename, umode_t mode,
+ unsigned dev);
Are these really needed?
91 of ~160 wrapped syscalls produce compile time error without it on
arm64:
arch/arm64/kernel/sys_ilp32.c:59:35: error: ‘compat_sys_io_destroy’ undeclared here (not in a function)
#define __SC_WRAP(nr, sym) [nr] = compat_##sym,
^
include/uapi/asm-generic/unistd.h:39:1: note: in expansion of macro ‘__SC_WRAP’
__SC_WRAP(__NR_io_destroy, sys_io_destroy)
^
I think, it's better to leave it as is...
Post by Heiko CarstensI'd really prefer if the existing common SYSCALL_DEFINE macros could be
extended to also generate the compat wrappers, if needed.
This probably means that you need another set of SYSCALL_DEFINE macros,
e.g. something like SYSCALL_COMPAT, which is defined the same like
SYSCALL_DEFINE, except that it also generates the compat_wrapper functions.
Since the list of system calls that need a wrapper is already present in
s390's compat_wrapper.c file it's "only" a matter of writing a script that
converts the required SYSCALL_DEFINEs to SYSYCALL_COMPATs.
It turns even better because most syscalls are just wrappers like:
SYSCALL_DEFINE(foo)
{
do_foo();
}
And with your approach GCC inlines sys_foo() that saves few cpu
cycles and stack:
<SyS_truncate>: <compat_SyS_truncate>
stp x29, x30, [sp,#-16]! stp x29, x30, [sp,#-16]!
mov x29, sp mov x29, sp
bl ca8 <do_sys_truncate> sxtw x1, w1
ldp x29, x30, [sp],#16 bl ca8 <do_sys_truncate>
ret ldp x29, x30, [sp],#16
nop ret
Thank you for adwise. See below what turned out.
Build-tested on s390, x86_64.
Yury.
