1394: fix for recently added firewire patch that breaks things on ppc
Recently a patch was added for preliminary suspend/resume handling on
!PPC_PMAC. However, this broke both suspend and firewire on powerpc
because it saves the pci state after the device has already been disabled.
This moves the save state to before the pmac specific code.

Fix BeFS slab corruption
In bugzilla #6941, Jens Kilian reported:
"The function befs_utf2nls (in fs/befs/linuxvfs.c) writes a 0 byte past the
end of a block of memory allocated via kmalloc(), leading to memory
corruption. This happens only for filenames which are pure ASCII and a
multiple of 4 bytes in length. [...]
Without DEBUG_SLAB, this leads to further corruption and hard lockups; I
believe this is the bug which has made kernels later than 2.6.8 unusable
for me. (This must be due to changes in memory management, the bug has
been in the BeFS driver since the time it was introduced (AFAICT).)
Steps to reproduce:
Create a directory (in BeOS, naturally :-) with files named, e.g.,
"1", "22", "333", "4444", ... Mount it in Linux and do an "ls" or "find""

F.e. timer has fired on CPU2, but the handler was preeempted
by an irq before dst_lock is tried.

starts the timer.

cond_resched() fix
Fix a bug identified by Zou Nan hai <nanhai.zou@intel.com>:
If the system is in state SYSTEM_BOOTING, and need_resched() is true,
cond_resched() returns true even though it didn't reschedule. Consequently
need_resched() remains true and JBD locks up.
Fix that by teaching cond_resched() to only return true if it really did call
schedule().
cond_resched_lock() and cond_resched_softirq() have a problem too. If we're
in SYSTEM_BOOTING state and need_resched() is true, these functions will drop
the lock and will then try to call schedule(), but the SYSTEM_BOOTING state
will prevent schedule() from being called. So on return, need_resched() will
still be true, but cond_resched_lock() has to return 1 to tell the caller that
the lock was dropped. The caller will probably lock up.
Bottom line: if these functions dropped the lock, they _must_ call schedule()
to clear need_resched(). Make it so.
Also, uninline __cond_resched(). It's largeish, and slowpath.

Fix race related problem when adding items to and svcrpc auth cache.
If we don't find the item we are lookng for, we allocate a new one,
and then grab the lock again and search to see if it has been added
while we did the alloc.
If it had been added we need to 'cache_put' the newly created item
that we are never going to use. But as it hasn't been initialised
properly, putting it can cause an oops.
So move the ->init call earlier to that it will always be fully

Update frag_list in pskb_trim
[NET]: Update frag_list in pskb_trim
When pskb_trim has to defer to ___pksb_trim to trim the frag_list part of
the packet, the frag_list is not updated to reflect the trimming. This
will usually work fine until you hit something that uses the packet length
or tail from the frag_list.
Examples include esp_output and ip_fragment.
Another problem caused by this is that you can end up with a linear packet
with a frag_list attached.
It is possible to get away with this if we audit everything to make sure
that they always consult skb->len before going down onto frag_list. In
fact we can do the samething for the paged part as well to avoid copying
the data area of the skb. For now though, let's do the conservative fix
and update frag_list.

UHCI: Fix handling of short last packet
This patch (as753) fixes the way uhci-hcd handles a short packet when it
is the last packet of an URB. Right now the driver handles short packets
the same no matter when they occur. However, the controller stops
transferring packets when the short packet is not the last one (otherwise
it would be reading beyond the end of the device's data) and needs to be
restarted, whereas no such need occurs when the short packet is the last

According to Petr Vandrovec:
... "What is important (and checked) is address of MMCONFIG reported by MCFG
table... Unfortunately code does not bother with printing that address :-(
"Another problem is that code has hardcoded that MMCONFIG area is 256MB large.
Unfortunately for the code PCI specification allows any power of two between 2MB
and 256MB if vendor knows that such amount of busses (from 2 to 128) will be
sufficient for system. With notebook it is quite possible that not full 8 bits
are implemented for MMCONFIG bus number."
So here is a patch. Unfortunately my system still fails the test because
it doesn't reserve any part of the MMCONFIG area, but this may fix others.
Booted on x86_64, only compiled on i386. x86_64 still remaps the max area
(256MB) even though only 2MB is checked... but 2.6.16 had no check at all
so it is still better.
PCI: reduce size of x86 MMCONFIG reserved area check
1. Print the address of the MMCONFIG area when the test for that area
being reserved fails.
2. Only check if the first 2MB is reserved, as that is the minimum.

pdflush is carefully designed to ensure that all wakeups have some

it hasn't been given any work to do then this is considered an error.
That all broke when swsusp came along - because a timer-delivered

be re-armed by pdflush in process context, but pdflush doesn't execute

generic_file_buffered_write(): handle zero-length iovec segments
The recent generic_file_write() deadlock fix caused
generic_file_buffered_write() to loop inifinitely when presented with a

Note that this fix deliberately avoids calling ->prepare_write(),
->commit_write() etc with a zero-length write. This is because I don't trust
all filesystems to get that right.
This is a cautious approach, for 2.6.17.x. For 2.6.18 we should just go ahead
and call ->prepare_write() and ->commit_write() with the zero length and fix
any broken filesystems. So I'll make that change once this code is stabilised
and backported into 2.6.17.x.
The reason for preferring to call ->prepare_write() and ->commit_write() with
the zero-length segment: a zero-length segment _should_ be sufficiently
uncommon that this is the correct way of handling it. We don't want to
optimise for poorly-written userspace at the expense of well-written

generic_file_buffered_write() prefaults in user pages in order to avoid
deadlock on copying from the same page as write goes to.
However, it looks like there is a problem when write is vectored:
fault_in_pages_readable brings in current segment or its part (maxlen).
OTOH, filemap_copy_from_user_iovec is called to copy number of bytes
(bytes) which may exceed current segment, so filemap_copy_from_user_iovec
switches to the next segment which is not brought in yet. Pagefault is

write goes to: page being written is locked and not uptodate, pagefault
will deadlock trying to lock locked page.

USB serial ftdi_sio: Prevent userspace DoS (CVE-2006-2936)
This patch limits the amount of outstanding 'write' data that can be
queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or
simple accidents) that use up all the system memory by writing lots of
data to the serial port.
The original patch was by Guillaume Autran, who in turn based it on the
same mechanism implemented in the 'visor' driver. I (Ian Abbott)
re-targeted the patch to the latest sources, fixed a couple of errors,
renamed his new structure members, and updated the implementations of
the 'write_room' and 'chars_in_buffer' methods to take account of the
number of outstanding 'write' bytes. It seems to work fine, though at
low baud rates it is still possible to queue up an amount of data that
takes an age to shift (a job for another day!).

splice: fix problems with sys_tee()
Several issues noticed/fixed:
- We cannot reliably block in link_pipe() while holding both input and output
mutexes. So do preparatory checks before locking down both mutexes and doing
the link.
- The ipipe->nrbufs vs i check was bad, because we could have dropped the
ipipe lock in-between. This causes us to potentially look at unknown
buffers if we were racing with someone else reading this pipe.
