A bunch of compat bugs fixed - some still remain, but all more or less generic tty-related ioctls should be covered (remaining issues are in things like driver-private ioctls in a pcmcia serial card driver not getting properly handled in 32bit processes on 64bit host, etc)" * 'work.tty-ioctl' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (53 commits) kill TIOCSERGSTRUCT change semantics of ldisc ->compat_ioctl() kill TIOCSER[SG]WILD synclink_gt(): fix compat_ioctl() pty: fix compat ioctls compat_ioctl - kill keyboard ioctl handling gigaset: add ->compat_ioctl() vt_compat_ioctl(): clean up, use compat_ptr() properly gigaset: don't try to printk userland buffer contents dgnc: don't bother with (empty) stub for TCXONC dgnc: leave TIOC[GS]SOFTCAR to ldisc remove fallback to drivers for TIOCGICOUNT dgnc: break-related ioctls won't reach ->ioctl() kill the rest of tty COMPAT_IOCTL() entries dgnc: TIOCM... won't reach ->ioctl() isdn_tty: TCSBRK{,P} won't reach ->ioctl() kill capinc_tty_ioctl() take compat TIOC[SG]SERIAL treatment into tty_compat_ioctl() synclink: reduce pointless checks in ->ioctl() complete ->[sg]et_serial() switchover ...

iov_iter: Separate type from direction and use accessor functions

2018-10-23T23:41:07Z

In the iov_iter struct, separate the iterator type from the iterator direction and use accessor functions to access them in most places. Convert a bunch of places to use switch-statements to access them rather then chains of bitwise-AND statements. This makes it easier to add further iterator types. Also, this can be more efficient as to implement a switch of small contiguous integers, the compiler can use ~50% fewer compare instructions than it has to use bitwise-and instructions. Further, cease passing the iterator type into the iterator setup function. The iterator function can set that itself. Only the direction is required. Signed-off-by: David Howells

Bluetooth: Remove redundant check on status

2018-10-14T08:31:25Z

The check on status is redundant as a status has to be zero at the point it is being checked because of a previous check and return path via label 'unlock'. Remove the redundant check and the deadcode that can never be reached. Detected by CoverityScan, CID#1471710 ("Logically dead code") Signed-off-by: Colin Ian King Signed-off-by: Marcel Holtmann

kill TIOCSERGSTRUCT

2018-10-13T04:50:53Z

Once upon a time a bunch of serial drivers used to provide that; today it's only amiserial and it's FUBAR - the structure being copied to userland includes kernel pointers, fields with config-dependent size, etc. No userland code using it could possibly survive - e.g. enabling lockdep definitely changes the layout. Besides, it's a massive infoleak. Kill it. If somebody needs that data for debugging purposes, they can bloody well expose it saner ways. Assuming anyone does debugging of amiserial in the first place, that is. Signed-off-by: Al Viro
