ip2: return -EFAULT on copy_to_user errors

2010-08-24T01:17:21Z

copy_to_user() returns the number of bytes remaining but we want to return a negative error code on errors. Signed-off-by: Dan Carpenter Cc: "Michael H. Warfield" Signed-off-by: Andrew Morton Signed-off-by: Greg Kroah-Hartman

ip2: remove unneeded NULL check

2010-08-24T01:17:20Z

We don't pass NULL tty pointers to the close function, and anyway we already dereferenced it at this point. This check can be removed. Signed-off-by: Dan Carpenter Cc: "Michael H. Warfield" Signed-off-by: Andrew Morton Signed-off-by: Greg Kroah-Hartman

tty: release BTM while sleeping in block_til_ready

2010-08-10T20:47:44Z

Most tty drivers may block while opening a device. Since this possibly depends on another thread closing it first and both threads may need the BTM, we need to release it here. Signed-off-by: Arnd Bergmann Cc: Alan Cox Signed-off-by: Greg Kroah-Hartman

ip2: Add module parameter.

2010-03-02T22:43:14Z

Stephen Rothwell found the following warning (x86_64 allmodconfig): drivers/char/ip2/ip2main.c:511: warning: 'ip2_setup' defined but not used This patch adds module parameter to fix the above warning. Signed-off-by: Rakib Mullick Signed-off-by: Greg Kroah-Hartman

ip2: remove #ifdef MODULE from ip2main.c

2010-03-02T22:43:14Z

On the kernel command line we can pass "module parameters". So #ifdef MODULE is obsolute now. Remove it completely. When CONFIG_PCI=n and building ip2main.c then we are hit by the following warning. So move *pdev into #ifdef CONFIG_PCI. drivers/char/ip2/ip2main.c: In function `ip2_loadmain': drivers/char/ip2/ip2main.c:542: warning: unused variable `pdev' Signed-off-by: Rakib Mullick Acked-by: Michael H.

tree-wide: Assorted spelling fixes

2010-02-09T10:13:56Z

In particular, several occurances of funny versions of 'success', 'unknown', 'therefore', 'acknowledge', 'argument', 'achieve', 'address', 'beginning', 'desirable', 'separate' and 'necessary' are fixed. Signed-off-by: Daniel Mack Cc: Joe Perches Cc: Junio C Hamano Signed-off-by: Jiri Kosina

tty: rewrite the ldisc locking

2009-06-11T15:51:01Z

There are several pretty much unfixable races in the old ldisc code, especially with respect to pty behaviour and also to hangup. It's easier to rewrite the code than simply try and patch it up. This patch - splits the ldisc from the tty (so we will be able to refcount it more cleanly later) - introduces a mutex lock for ldisc changing on an active device - fixes the complete mess that hangup caused - implements hopefully correct setldisc/close/hangup locking There are still some problems around pty pairs that have always been there but at least it is now possible to understand the code and fix further problems. This fixes the following known bugs - hang up can leak ldisc references - hang up may not call open/close on ldisc in a matched way - pty/tty pairs can deadlock during an ldisc change - reading the ldisc proc files can cause every ldisc to be loaded and probably a few other of the mysterious ldisc race reports. I'm sure it also adds the odd new one. Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds
