When we copy 32bit ->msg_control contents to kernel, we walk the same
userland data twice without sanity checks on the second pass.Second version of this patch: the original broke with 64-bit arches
running 32-bit-compat-mode executables doing sendmsg() syscalls with
unaligned CMSG data areasAnother thing is that we use kmalloc() to allocate and sock_kfree_s()
to free afterwards; less serious, but also needs fixing.Signed-off-by: Al Viro

With the previous commit that introduces the klist enhancements, we can
now re-do 2b7d6a8cb9718fc1d9e826201b64909c44a915f4 again. -
The problem is that klists claim to provide semantics for safe traversal of
lists which are being modified. The failure case is when traversal of a
list causes element removal (a fairly common case). The issue is that
although the list node is refcounted, if it is embedded in an object (which
is universally the case), then the object will be freed regardless of the
klist refcount leading to slab corruption because the klist iterator refers
to the prior element to get the next.The solution is to make the klist take and release references to the
embedding object meaning that the embedding object won't be released until
the list relinquishes the reference to it.(akpm: fast-track this because it's needed for the 2.6.13 scsi merge)

Revert commit 2b7d6a8cb9718fc1d9e826201b64909c44a915f4.
The "fix" was known to not even compile. Duh. That's not a fix.
That's just stupid.Signed-off-by: Linus Torvalds

A piece of the UML stubs patch got lost - it has
Killed STUBS_CFLAGS - it's not needed and the only remaining use had been
gratitious - it only polluted CFLAGS
in description and does remove it in arch/um/Makefile-x86_64, but forgets to
do the same in i386 counterpart. Lost chunk follows:Signed-off-by: Al Viro

Sanitized and fixed floppy dependencies: split the messy dependencies for
BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making
BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC
to arch/*/Kconfig. While we are at it, fixed several obvious cases when
BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h
are *not* going to have floppy.c compile, let alone work).If you can come up with better name for that ("this architecture might
have working PC-compatible floppy disk controller"), you are more than
welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch
below...Signed-off-by: Al Viro

Most of the patch is whitespace cleanup, but more importantly, this patch
checks to see whether a callback is set before calling it. On cx88 boards
(currently the only boards using lgdt330x in 2.6.13) every callback is set.
However, newer drivers currently in development leave a callback undefined,
and lgdt330x must not call it if it isn't defined.Signed-off-by: Patrick Boettcher

Patrick Keene wrote to the linux-dvb list, asking where in menuconfig he
can enable dvb-bt8xx for his AVerMedia DVB card. I pointed the following
out to him:config DVB_BT8XX
tristate "Nebula/Pinnacle PCTV/Twinhan PCI cards"It has been agreed upon that this description is extremely misleading.
This patch changes the one-liner description text of dvb-bt8xx to something
more meaningful, and adds AVerMedia to the detailed description.Signed-off-by: Michael Krufky

Fix http://bugzilla.kernel.org/show_bug.cgi?id=4857
When pivot_root is called from an init script in an initramfs environment,
it causes a circular reference in the mount tree.The cause of this is that pivot_root() is not prepared to handle pivoting
an unattached mount. In an initramfs environment, rootfs is the root of
the namespace, and so it is not attached.This patch fixes this and related problems, by returning -EINVAL if either
the current root or the new root is detached.Signed-off-by: Miklos Szeredi

This patch fixes a race condition where in system used to hang or sometime
crash within minutes when kprobes are inserted on ISR routine and a task
routine.The fix has been stress tested on i386, ia64, pp64 and on x86_64. To
reproduce the problem insert kprobes on schedule() and do_IRQ() functions
and you should see hang or system crash.Signed-off-by: Anil S Keshavamurthy

This patch fixes a bug in kprobes's handling of a corner case on i386 and
x86_64. On an SMP system, if one CPU unregisters a kprobe just after
another CPU hits that probepoint, kprobe_handler() on the latter CPU sees
that the kprobe has been unregistered, and attempts to let the CPU continue
as if the probepoint hadn't been hit. The bug is that on i386 and x86_64,
we were neglecting to set the IP back to the beginning of the probed
instruction. This could cause an oops or crash.This bug doesn't exist on ppc64 and ia64, where a breakpoint instruction
leaves the IP pointing to the beginning of the instruction. I don't know
about sparc64. (Dave, could you please advise?)This fix has been tested on i386 and x86_64 SMP systems. To reproduce the
problem, set one CPU to work registering and unregistering a kprobe
repeatedly, and another CPU pounding the probepoint in a tight loop.Acked-by: Prasanna S Panchamukhi
