This fixes CERT-FI FICORA #341748
Discovered by Olli Jarva and Tuomo Untinen from the CROSS
project at Codenomicon Ltd.
Just like in CVE-2007-4567, we can't rely upon skb_dst() being
non-NULL at this point. We fixed that in commit
e76b2b2567b83448c2ee85a896433b96150c92e6 ("[IPV6]: Do no rely on
skb->dst before it is assigned.")
However commit 483a47d2fe794328d29950fe00ce26dd405d9437 ("ipv6: added
net argument to IP6_INC_STATS_BH") put a new version of the same bug
into this function.
Complicating analysis further, this bug can only trigger when network
namespaces are enabled in the build. When namespaces are turned off,
the dev_net() does not evaluate it's argument, so the dereference
would not occur.
So, for a long time, namespaces couldn't be turned on unless SYSFS was
disabled. Therefore, this code has largely been disabled except by
people turning it on explicitly for namespace development.

The B0 revision of the 5717 will not get enough testing by the time
2.6.33 ships. Since the kernel is already at RC3, serdes support
will require too many patches to fix. For these reasons, this patch
disables 5717 serdes support and will refuse to attach to all 5717
devices that are later than an A0 revision.

There are some tg3 devices that require the driver to post new rx
buffers in smaller increments. Commit
4361935afe3abc3e5a93006b99197fac1fabbd50, "tg3: Consider
rx_std_prod_idx a hw mailbox" changed how the driver tracks the rx
producer ring updates, but it does not make any special considerations
for the above-mentioned devices. For those devices, it is possible for
the driver to hit the special case path, which updates the hardware
mailbox register but skips updating the shadow software mailbox member.
If the special case path represents the final mailbox update for this
ISR iteration, the hardware and software mailbox values will be out of
sync. Ultimately, this will cause the driver to use a stale mailbox
value on the next iteration, which will appear to the hardware as a
large rx buffer update. Bad things ensue.
The fix is to update the software shadow mailbox member when the special
case path is taken.

Commit 87668d352aa8d135bd695a050f18bbfc7b50b506, titled "tg3: Don't
touch RCB nic addresses", tried to avoid assigning the nic address of
the standard producer ring. Unfortunately, the default nic address is
not correct for the 5787, the 5755M, or the 57765. This patch
reenables the old behavior and opts out of the assignment only
for the 5717.

When the interface is down and we are using polled mode for MCDI
operations, we busy-wait for completion for approximately 1 jiffy
using udelay() and then back off to schedule(). But the completion
will not wake the task, since we are using polled mode! We must use
schedule_timeout_uninterruptible() instead.

A previous 82577 workaround that set the MDIO access speed to slow mode for
every PHY register read/write when the cable is unplugged should instead
set the access mode to always be slow before any PHY register access.
Since the mode bit gets cleared when the PHY is reset, set the mode after
every PHY reset.

Commit ac4c2a3bbe5db5fc570b1d0ee1e474db7cb22585 broke the build
of all powerpc boot wrappers.
It attempts to add an include of autoconf.h but used the wrong
path for it. It also adds -D__KERNEL__ to our boot wrapper, both
things that we pretty much didn't do on purpose so far.
We want our boot wrapper to remain independent enough of the kernel
for various reasons, one of them being that you can "wrap" an existing
kernel at distro install time which allows to ship one kernel image
and a set of boot wrappers for different platforms, the wrappers
don't have to be built out of the same kernel build tree.
It's also incorrect to do what the patch does in our boot environment
since we may not have a proper alignment exception handler which means
we may not be able to fixup the few cases where an unaligned access will
need SW emulation (depends on the core variant, could be when crossing
page or segment boundaries for example).
This patch fixes it by putting the old code back in and using the
new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
is set, which happens not to be set on powerpc since we don't include
autoconf.h. It also reverts the changes to our boot wrapper Makefile.
This means that x86 should, afaik, keep the optimisations since its
boot wrapper does include autoconf.h and define __KERNEL__ (though I
doubt they make that much different outside of slow embedded processors).

If __block_prepare_write() was failed in block_write_begin(), the
allocated blocks can be outside of ->i_size.
But new truncate_pagecache() in vmtuncate() does nothing if new < old.
It means the above usage is not working anymore.
So, this patch fixes it by removing "new < old" check. It would need
more cleanup/change. But, now -rc and truncate working is in progress,
so, this tried to fix it minimum change.

Setting LC_CTYPE=C breaks localized messages in some setups. With only
LC_COLLATE=C and LC_NUMERIC=C, we get almost all we need, except for not
so defined character classes and tolower()/toupper(). The former is not
a big issue, because we can assume that e.g. [:alpha:] will always
include a-zA-Z and we only ever process ASCII input. The latter seems
only affect arch/sh/tools/gen-mach-types, which we can handle separately.
So after this patch the meaning of ranges like [a-z], the behavior of
sort and join, etc. should be the same everywhere and at the same time
gcc should be able to print localized waring and error messages.
LC_NUMERIC=C might not be necessary, but setting it doesn't hurt.

In an x86 build with CONFIG_KERNEL_LZMA enabled and dash as sh,
arch/x86/boot/compressed/vmlinux.bin.lzma ends with
'\xf0\x7d\x39\x00' (16 bytes) instead of the 4 bytes intended and
the resulting vmlinuz fails to boot. This improves on the
previous behavior, in which the file contained the characters
'-ne ' as well, but not by much.
Previous commits replaced "echo -ne" first with "/bin/echo -ne",
then "printf" in the hope of improving portability, but none of
these commands is guaranteed to support hexadecimal escapes on
POSIX systems. So use the shell to convert from hexadecimal to
octal.
With this change, an LZMA-compressed kernel built with dash as sh
boots correctly again.
