From: Al Viro <viro@zeniv.linux.org.uk> commit 6b2daec19094a90435abe67d16fb43b1a5527254 upstream. Unlike FICLONE, all of those take a pointer argument; they do need compat_ptr() applied to arg. Fixes: d79bdd52d8be ("vfs: wire up compat ioctl for CLONE/CLONE_RANGE") Fixes: 54dbc1517237 ("vfs: hoist the btrfs deduplication ioctl to the vfs") Fixes: ceac204e1da9 ("fs: make fiemap work from compat_ioctl") Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> --- fs/compat_ioctl.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/fs/compat_ioctl.c b/fs/compat_ioctl.c index 3a03f74..c6fe991 100644 --- a/fs/compat_ioctl.c +++ b/fs/compat_ioctl.c @@ -1401,10 +1401,11 @@ static int compat_ioctl_check_table(unsigned int xcmd) #endif case FICLONE: + goto do_ioctl; case FICLONERANGE: case FIDEDUPERANGE: case FS_IOC_FIEMAP: - goto do_ioctl; + goto found_handler; case FIBMAP: case FIGETBSZ: -- 1.8.3
