vfs: fix up ENOIOCTLCMD error handling

2012-01-05T23:40:12Z

We're doing some odd things there, which already messes up various users (see the net/socket.c code that this removes), and it was going to add yet more crud to the block layer because of the incorrect error code translation. ENOIOCTLCMD is not an error return that should be returned to user mode from the "ioctl()" system call, but it should *not* be translated as EINVAL ("Invalid argument"). It should be translated as ENOTTY ("Inappropriate ioctl for device"). That EINVAL confusion has apparently so permeated some code that the block layer actually checks for it, which is sad. We continue to do so for now, but add a big comment about how wrong that is, and we should remove it entirely eventually. In the meantime, this tries to keep the changes localized to just the EINVAL -> ENOTTY fix, and removing code that makes it harder to do the right thing. Signed-off-by: Linus Torvalds

[media] fs/compat_ioctl: it needs to see the DVBv3 compat stuff

2011-12-31T18:57:27Z

Only the ioctl core should see the DVBv3 compat stuff, as its contents are not available anymore to the drivers. As fs/compat_ioctl also handles DVBv3 ioctl's, it needs those definitions: fs/compat_ioctl.c:1345: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1345: error: array type has incomplete element type fs/compat_ioctl.c:1345: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1345: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1345: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1345: error: array type has incomplete element type fs/compat_ioctl.c:1345: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1345: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1345: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1345: error: array type has incomplete element type fs/compat_ioctl.c:1345: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1345: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1345: error: initializer element is not constant fs/compat_ioctl.c:1345: error: (near initialization for ‘ioctl_pointer[462]’) fs/compat_ioctl.c:1346: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1346: error: array type has incomplete element type fs/compat_ioctl.c:1346: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1346: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1346: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1346: error: array type has incomplete element type fs/compat_ioctl.c:1346: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1346: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1346: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1346: error: array type has incomplete element type fs/compat_ioctl.c:1346: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1346: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_parameters’ fs/compat_ioctl.c:1346: error: initializer element is not constant fs/compat_ioctl.c:1346: error: (near initialization for ‘ioctl_pointer[463]’) fs/compat_ioctl.c:1347: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_event’ fs/compat_ioctl.c:1347: error: array type has incomplete element type fs/compat_ioctl.c:1347: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_event’ fs/compat_ioctl.c:1347: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_event’ fs/compat_ioctl.c:1347: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_event’ fs/compat_ioctl.c:1347: error: array type has incomplete element type fs/compat_ioctl.c:1347: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_event’ fs/compat_ioctl.c:1347: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_event’ fs/compat_ioctl.c:1347: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_event’ fs/compat_ioctl.c:1347: error: array type has incomplete element type fs/compat_ioctl.c:1347: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_event’ fs/compat_ioctl.c:1347: error: invalid application of ‘sizeof’ to incomplete type ‘struct dvb_frontend_event’ fs/compat_ioctl.c:1347: error: initializer element is not constant fs/compat_ioctl.c:1347: error: (near initialization for ‘ioctl_pointer[464]’) Reported-by: Michael Krufky Signed-off-by: Mauro Carvalho Chehab

compat_ioctl: add compat handler for PPPIOCGL2TPSTATS

compat_ioctl: fix warning caused by qemu

2011-07-01T20:32:26Z

On Linux x86_64 host with 32bit userspace, running qemu or even just "qemu-img create -f qcow2 some.img 1G" causes a kernel warning: ioctl32(qemu-img:5296): Unknown cmd fd(3) cmd(00005326){t:'S';sz:0} arg(7fffffff) on some.img ioctl32(qemu-img:5296): Unknown cmd fd(3) cmd(801c0204){t:02;sz:28} arg(fff77350) on some.img ioctl 00005326 is CDROM_DRIVE_STATUS, ioctl 801c0204 is FDGETPRM. The warning appears because the Linux compat-ioctl handler for these ioctls only applies to block devices, while qemu also uses the ioctls on plain files.

[media] V4L1 removal: Remove linux/videodev.h

2010-12-29T10:17:11Z

There's no sense on keeping it on 2.6.38, as nobody is using it anymore, at the kernel tree, and installing it at the userspace API. As two deprecated drivers still need it, move it to their internal directories. Reviewed-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
