netlabel: Fix build problems when IPv6 is not enabled
A recent fix to the the NetLabel code caused build problem with
configurations that did not have IPv6 enabled; see below:
netlabel_kapi.c: In function 'netlbl_cfg_unlbl_map_add':
netlabel_kapi.c:165:4:
error: implicit declaration of function 'netlbl_af6list_add'
This patch fixes this problem by making the IPv6 specific code conditional
on the IPv6 configuration flags as we done in the rest of NetLabel and the
network stack as a whole. We have to move some variable declarations
around as a result so things may not be quite as pretty, but at least it
builds cleanly now.
Some additional IPv6 conditionals were added to the NetLabel code as well
for the sake of consistency.

sctp: better integer overflow check in sctp_auth_create_key()
The check from commit 30c2235c is incomplete and cannot prevent
cases like key_len = 0x80000000 (INT_MAX + 1). In that case, the
left-hand side of the check (INT_MAX - key_len), which is unsigned,
becomes 0xffffffff (UINT_MAX) and bypasses the check.
However this shouldn't be a security issue. The function is called
from the following two code paths:
1) setsockopt()
2) sctp_auth_asoc_set_secret()
In case (1), sca_keylength is never going to exceed 65535 since it's
bounded by a u16 from the user API. As such, the key length will
never overflow.
In case (2), sca_keylength is computed based on the user key (1 short)
and 2 * key_vector (3 shorts) for a total of 7 * USHRT_MAX, which still
will not overflow.
In other words, this overflow check is not really necessary. Just
make it more correct.

Amidst reorganizing 'try_one_irq', that patch removed a test that
checked for 'action->handler' returning IRQ_HANDLED, before acting on
the interrupt. Restoring this test back returns the functionality lost
since 2.6.39. In the current set of tests, after 'action' is set, it

virtio-pci: make reset operation safer

virtio: add HAS_IOMEM dependency to MMIO platform bus driver
virtio pci device reset actually just does an I/O
write, which in PCI is really posted, that is it
can complete on CPU before the device has received it.
Further, interrupts might have been pending on
another CPU, so device callback might get invoked after reset.
This conflicts with how drivers use reset, which is typically:
reset
unregister
a callback running after reset completed can race with
unregister, potentially leading to use after free bugs.
Fix by flushing out the write, and flushing pending interrupts.
This assumes that device is never reset from
its vq/config callbacks, or in parallel with being
added/removed, document this assumption.

qlge: fix size of external list for TX address descriptors
When transmiting a fragmented skb, qlge fills a descriptor with the
fragment addresses, after DMA-mapping them. If there are more than eight
fragments, it will use the eighth descriptor as a pointer to an external
list. After mapping this external list, called OAL to a structure
containing more descriptors, it fills it with the extra fragments.
However, considering that systems with pages larger than 8KiB would have
less than 8 fragments, which was true before commit a715dea3c8e, it
defined a macro for the OAL size as 0 in those cases.
Now, if a skb with more than 8 fragments (counting skb->data as one
fragment), this would start overwriting the list of addresses already
mapped and would make the driver fail to properly unmap the right
addresses on architectures with pages larger than 8KiB.
Besides that, the list of mappings was one size too small, since it must
have a mapping for the maxinum number of skb fragments plus one for
skb->data and another for the OAL. So, even on architectures with page
sizes 4KiB and 8KiB, a skb with the maximum number of fragments would
make the driver overwrite its counter for the number of mappings, which,
again, would make it fail to unmap the mapped DMA addresses.

eCryptfs: Extend array bounds for all filename chars
From mhalcrow's original commit message:
Characters with ASCII values greater than the size of
filename_rev_map[] are valid filename characters.
ecryptfs_decode_from_filename() will access kernel memory beyond
that array, and ecryptfs_parse_tag_70_packet() will then decrypt
those characters. The attacker, using the FNEK of the crafted file,
can then re-encrypt the characters to reveal the kernel memory past
the end of the filename_rev_map[] array. I expect low security
impact since this array is statically allocated in the text area,
and the amount of memory past the array that is accessible is
limited by the largest possible ASCII filename character.
This patch solves the issue reported by mhalcrow but with an
implementation suggested by Linus to simply extend the length of
filename_rev_map[] to 256. Characters greater than 0x7A are mapped to
0x00, which is how invalid characters less than 0x7A were previously
being handled.
