[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

fix rawctl compat ioctls breakage on amd64 and itanic

2010-10-19T09:29:54Z

RAW_SETBIND and RAW_GETBIND 32bit versions are fscked in interesting ways. 1) fs/compat_ioctl.c has COMPATIBLE_IOCTL(RAW_SETBIND) followed by HANDLE_IOCTL(RAW_SETBIND, raw_ioctl). The latter is ignored. 2) on amd64 (and itanic) the damn thing is broken - we have int + u64 + u64 and layouts on i386 and amd64 are _not_ the same. raw_ioctl() would work there, but it's never called due to (1). As it is, i386 /sbin/raw definitely doesn't work on amd64 boxen. 3) switching to raw_ioctl() as is would *not* work on e.g. sparc64 and ppc64, which would be rather sad, seeing that normal userland there is 32bit. The thing is, slapping __packed on the struct in question does not DTRT - it eliminates *all* padding. The real solution is to use compat_u64. 4) of course, all that stuff has no business being outside of raw.c in the first place - there should be ->compat_ioctl() for /dev/rawctl instead of messing with compat_ioctl.c.

smbfs: move to drivers/staging

2010-10-05T16:08:21Z

smbfs has been scheduled for removal in 2.6.27, so maybe we can now move it to drivers/staging on the way out. smbfs still uses the big kernel lock and nobody is going to fix that, so we should be getting rid of it soon. This removes the 32 bit compat mount and ioctl handling code, which is implemented in common fs code, and moves all smbfs related files into drivers/staging/smbfs.

tty: Add EXTPROC support for LINEMODE

2010-08-10T20:47:39Z

This patch is against the 2.6.34 source. Paraphrased from the 1989 BSD patch by David Borman @ cray.com: These are the changes needed for the kernel to support LINEMODE in the server. There is a new bit in the termios local flag word, EXTPROC. When this bit is set, several aspects of the terminal driver are disabled. Input line editing, character echo, and mapping of signals are all disabled. This allows the telnetd to turn off these functions when in linemode, but still keep track of what state the user wants the terminal to be in. New ioctl: TIOCSIG Generate a signal to processes in the current process group of the pty. There is a new mode for packet driver, the TIOCPKT_IOCTL bit. When packet mode is turned on in the pty, and the EXTPROC bit is set, then whenever the state of the pty is changed, the next read on the master side of the pty will have the TIOCPKT_IOCTL bit set. This allows the process on the server side of the pty to know when the state of the terminal has changed; it can then issue the appropriate ioctl to retrieve the new state. Since the original BSD patches accompanied the source code for telnet I've left that reference here, but obviously the feature is useful for any remote terminal protocol, including ssh. The corresponding feature has existed in the BSD tty driver since 1989.
