[NETFILTER] Fix conntrack event cache deadlock/oops

This patch fixes a number of bugs.  It cannot be reasonably split up in
multiple fixes, since all bugs interact with each other and affect the same
function:

Bug #1:
The event cache code cannot be called while a lock is held.  Therefore, the
call to ip_conntrack_event_cache() within ip_ct_refresh_acct() needs to be
moved outside of the locked section.  This fixes a number of 2.6.14-rcX
oops and deadlock reports.

Bug #2:
We used to call ct_add_counters() for unconfirmed connections without
holding a lock.  Since the add operations are not atomic, we could race
with another CPU.

Bug #3:
ip_ct_refresh_acct() lost REFRESH events in some cases where refresh
(and the corresponding event) are desired, but no accounting shall be
performed.  Both, evenst and accounting implicitly depended on the skb
parameter bein non-null.   We now re-introduce a non-accounting
"ip_ct_refresh()" variant to explicitly state the desired behaviour.

Herbert Xu [Fri, 23 Sep 2005 06:32:56 +0000]
[TCP]: Adjust Reno SACK estimate in tcp_fragment

Since the introduction of TSO pcount a year ago, it has been possible
for tcp_fragment() to cause packets_out to decrease.  Prior to that,
tcp_retrans_try_collapse() was the only way for that to happen on the
retransmission path.

When this happens with Reno, it is possible for sasked_out to become
invalid because it is only an estimate and not tied to any particular
packet on the retransmission queue.

Therefore we need to adjust sacked_out as well as left_out in the Reno
case.  The following patch does exactly that.

This bug is pretty difficult to trigger in practice though since you
need a SACKless peer with a retransmission that occurs just as the
cached MTU value expires.

[PATCH] Fix bd_claim() error code.

Problem: In some circumstances, bd_claim() is returning the wrong error
code.

If we try to swapon an unused block device that isn't swap formatted, we
get -EINVAL.  But if that same block device is already mounted, we instead
get -EBUSY, even though it still isn't a valid swap device.

This issue came up on the busybox list trying to get the error message
from "swapon -a" right.  If a swap device is already enabled, we get -EBUSY,
and we shouldn't report this as an error.  But we can't distinguish the two
-EBUSY conditions, which are very different errors.

In the code, bd_claim() returns either 0 or -EBUSY, but in this case busy
means "somebody other than sys_swapon has already claimed this", and
_that_ means this block device can't be a valid swap device.  So return
-EINVAL there.

14 years ago[PATCH] uml: avoid fixing faults while atomic
Paolo 'Blaisorblade' Giarrusso [Fri, 23 Sep 2005 04:44:20 +0000]
[PATCH] uml: avoid fixing faults while atomic

Following i386, we should maybe refuse trying to fault in pages when we're
doing atomic operations, because to handle the fault we could need to take
already taken spinlocks.

Also, if we're doing an atomic operation (in the sense of in_atomic()) we're
surely in kernel mode and we're surely going to handle adequately the failed
fault, so it's safe to behave this way.

Currently, on UML SMP is rarely used, and we don't support PREEMPT, so this is
unlikely to create problems right now, but it might in the future.

Paolo 'Blaisorblade' Giarrusso [Fri, 23 Sep 2005 04:44:19 +0000]
[PATCH] uml: run mconsole "sysrq" in process context

Things are breaking horribly with sysrq called in interrupt context.  I want
to try to fix it, but probably this is simpler.  To tell the truth, sysrq is
normally run in interrupt context, so there shouldn't be any problem.

There's also a warning from the fault handler because it's run in atomic
context (I have a patch for that, only I deferred it).  This is why I'm doing
this.

Paolo 'Blaisorblade' Giarrusso [Fri, 23 Sep 2005 04:44:16 +0000]
[PATCH] uml: fix hang in TT mode on fault

The current code doesn't handle well general protection faults on the host -
it thinks that cr2 is always the address of a page fault.  While actually, on
general protection faults, that address is not accessible, so we'd better
assume we couldn't satisfy the fault.  Currently instead we think we've fixed
it, so we go back, retry the instruction and fault again endlessly.

This leads to the kernel hanging when doing copy_from_user(dest, -1, ...) in
TT mode, since reading *(-1) causes a GFP, and we don't support kernel
preemption.

Thanks to Luo Xin for testing UML with LTP and reporting the failures he got.

[PATCH] __kmalloc: Generate BUG if size requested is too large.

I had an issue on ia64 where I got a bug in kernel/workqueue because
kzalloc returned a NULL pointer due to the task structure getting too big
for the slab allocator.  Usually these cases are caught by the kmalloc
macro in include/linux/slab.h.

Compilation will fail if a too big value is passed to kmalloc.

However, kzalloc uses __kmalloc which has no check for that.  This patch
makes __kmalloc bug if a too large entity is requested.

[PATCH] ppc64: SMU driver update & i2c support

The current kernel contains a very crude driver that doesn't do much more
than reading the real time clock synchronously.  This is a completely
rewritten driver that provides interrupt based command queuing, a userland
interface, and an i2c/smbus driver for accessing the devices hanging off
the SMU i2c busses like temperature sensors.  This driver is a basic block
for upcoming work on thermal control for those machines, among others.

The numa slab allocator may allocate pages from foreign nodes onto the

the caller can indicate which node currently uses a slab.

Also removes the check for the current node from kmalloc_cache_node since
the process may shift later to another node which may lead to an allocation
on another node than intended.

Eric W. Biederman [Fri, 23 Sep 2005 04:43:46 +0000]
[PATCH] suspend: cleanup calling of power off methods.

In the lead up to 2.6.13 I fixed a large number of reboot problems by
making the calling conventions consistent.  Despite checking and double
checking my work it appears I missed an obvious one.

The S4 suspend code for PM_DISK_PLATFORM was also calling device_shutdown
without setting system_state, and was not calling the appropriate
reboot_notifier.

This patch fixes the bug by replacing the call of device_suspend with
kernel_poweroff_prepare.

Various forms of this failure have been fixed and tracked for a while.

[PATCH] USB: ftdi_sio: allow baud rate to be changed without raising RTS and DTR

I'm using a 2 port USB RS232 dongle to connect to a serial-IR cradle for
a bar code reader). Detecting the baudrate of the serial-IR involves
keeping DTR low while changing baudrate.

This works using normal 16550A serial ports as well as the FTDI driver
version 1.4.0 (Linux 2.6.8) but stopped working with the change to
"ensure RTS and DTR are raised when changing baudrate" introduced in
version 1.4.1 (Linux 2.6.9).

The attached patch fixes this, so RTS and DTR is only raised when
changing baudrate iff the previous baudrate was B0.

[PATCH] fix drivers/pci/probe.c warning

This function expects an unsigned 32-bit type as its third argument:

 static u32 pci_size(u32 base, u32 maxbase, u32 mask)

However, given these definitions:

 #define PCI_BASE_ADDRESS_MEM_MASK (~0x0fUL)
 #define PCI_ROM_ADDRESS_MASK (~0x7ffUL)

these two calls in drivers/pci/probe.c are problematic for architectures
for which a UL is not equivalent to a u32:

 sz = pci_size(l, sz, PCI_BASE_ADDRESS_MEM_MASK);
 sz = pci_size(l, sz, PCI_ROM_ADDRESS_MASK);

Hence the below compile warning when building for ARCH=ppc64:

 drivers/pci/probe.c: In function `pci_read_bases':
 /.../probe.c:168: warning: large integer implicitly truncated to unsigned type

14 years ago[PATCH] Driver Core: fis bus rescan devices race
Daniel Ritz [Thu, 22 Sep 2005 07:47:11 +0000]
[PATCH] Driver Core: fis bus rescan devices race

bus_rescan_devices_helper() does not hold the dev->sem when it checks for
!dev->driver().  device_attach() holds the sem, but calls again
device_bind_driver() even when dev->driver is set.

What happens is that a first device_attach() call (module insertion time)
is on the way binding the device to a driver.  Another thread calls
bus_rescan_devices().  Now when bus_rescan_devices_helper() checks for
dev->driver it is still NULL 'cos the the prior device_attach() is not yet
finished.  But as soon as the first one releases the dev->sem the second
device_attach() tries to rebind the already bound device again.
device_bind_driver() does this blindly which leads to a corrupt
driver->klist_devices list (the device links itself, the head points to the
device).  Later a call to device_release_driver() sets dev->driver to NULL
and breaks the link it has to itself on knode_driver.  Rmmoding the driver
later calls driver_detach() which leads to an endless loop 'cos the list
head in klist_devices still points to the device.  And since dev->driver is
NULL it's stuck with the same device forever.  Boom.  And rmmod hangs.

Very easy to reproduce with new-style pcmcia and a 16bit card.  Just loop
modprobe <pcmcia-modules> ;cardctl eject; rmmod <card driver, pcmcia
modules>.

Easiest fix is to check if the device is already bound to a driver in
device_bind_driver().  This avoids the double binding.

It was so bad that the compile warning I got was "control reaches end of
non-void function", i.e. missing return. Actually, this has been there for ages,
the consolidation patch just added the warning which was needed to clean it up.
Nice. Really.

14 years ago[PATCH] uml: comment about cast build fix
Paolo 'Blaisorblade' Giarrusso [Wed, 21 Sep 2005 16:40:29 +0000]
[PATCH] uml: comment about cast build fix

Explain why the casting we do to silence this warning is indeed safe.

It is because the field we're casting from, though being 64-bit wide, was filled
with a pointer in first place by ourselves.

[PATCH] uml: readd removed unistd.h inclusion

Readd this header (deleted in 60d339f6fe0831060600c62418b71a62ad26c281). A
warning is spit out here about undeclared getpgrp().

14 years ago[PATCH] uml: fix bogus HOST_ELF_CLASS symbol name
Paolo 'Blaisorblade' Giarrusso [Wed, 21 Sep 2005 16:39:47 +0000]
[PATCH] uml: fix bogus HOST_ELF_CLASS symbol name

Even if with a bit of misunderstanding, Al fixed this in commit
95608261dae863bc43292e6fbd946a3abd3aa49f.

Well, the symbol was intended to come from userspace (it exists there on normal
host), but since some hosts may miss that, using the kernel one is just as fine.
However, rename it to be named consistently with the rest.

Actually, he missed converting ELFCLASS32 to coming from kernel headers. For
consistence, add ELFCLASS64 too.
