Joel Soete reported oopses during pppoe over sundance NIC, caused by
a bug in skb allocation and dma mapping code, where skb_reserve()
bytes weren't taken into account. As a followup to the patch:
"sundance: Fix oopses with corrupted skb_shared_info" very similar
code is fixed here for three other drivers.

Joel Soete reported oopses at the beginning of pppoe connections since
v2.6.35. After debugging the bug was found in sundance skb allocation
and dma mapping code, where skb_reserve() bytes aren't taken into
account. This is an old bug, only uncovered by some change in 2.6.35.

The original code returns 0 on success and 1 on failure. In fact, at
this point, "ret" is already either zero or a negative error code so
we can just return it directly.

If the user-provided len is less than the expected offset, the
IRLMP_ENUMDEVICES getsockopt will do a copy_to_user() with a very large
size value. While this isn't be a security issue on x86 because it will
get caught by the access_ok() check, it may leak large amounts of kernel
heap on other architectures. In any event, this patch fixes it.

Alexey Vlasov found /proc/net/tcp could sometime loop and display
millions of sockets in LISTEN state.
In 2.6.29, when we converted TCP hash tables to RCU, we left two
sk_next() calls in listening_get_next().
We must instead use sk_nulls_next() to properly detect an end of chain.

All rt2x00 drivers except rt2800pci call ieee80211_tx_status() from
a workqueue, which causes "NOHZ: local_softirq_pending 08" messages.
To fix it, add ieee80211_tx_status_ni() similar to ieee80211_rx_ni()
which can be called from process context, and call it from
rt2x00lib_txdone(). For the rt2800pci special case a driver
flag is introduced.

The atl1c driver uses the legacy PCI power management, so it has to
do some PCI-specific things in its ->suspend() and ->resume()
callbacks and they are not done correctly.
Convert atl1c to the new PCI power management framework and make it
let the PCI subsystem handle all of the PCI-specific aspects of
device handling during system power transitions.

This function has three bugs:
1) The offset should be valid most of the time, this is just
a sanity check, therefore we should use "likely" not "unlikely"
2) This is the only place where we can check for arithmetic overflow
of the pointer plus the length.
3) The existing range checks are off by one, the valid range is
skb->head to skb_tail_pointer(), inclusive.
Based almost entirely upon a patch by Ralph Loader.

When deploying SFQ/IFB here at work, I found the allot management was
pretty wrong in sfq, even changing allot from short to int...
We should init allot for each new flow, not using a previous value found
in slot.
Before patch, I saw bursts of several packets per flow, apparently
denying the default "quantum 1514" limit I had on my SFQ class.
class sfq 11:1 parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 0b 7p requeues 0
allot 11546
class sfq 11:46 parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 0b 1p requeues 0
allot -23873
class sfq 11:78 parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 0b 5p requeues 0
allot 11393
After patch, better fairness among each flow, allot limit being
respected, allot is positive :
class sfq 11:e parent 11:
(dropped 0, overlimits 0 requeues 86)
backlog 0b 3p requeues 86
allot 596
class sfq 11:94 parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 0b 3p requeues 0
allot 1468
class sfq 11:a4 parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 0b 4p requeues 0
allot 650
class sfq 11:bb parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 0b 3p requeues 0
allot 596

Pawel reported a panic related to handling shared skbs in ixgbe
incorrectly. So we need to revert my previous patch to work around
this bug. Instead of reverting the patch completely, I just revert
the essential lines, so we can add the previous optimization
back more easily in future.

This patch modifies IPsec6 to fragment IPv6 packets that are
locally generated as needed.
This version of the patch only fragments in tunnel mode, so that fragment
headers will not be obscured by ESP in transport mode.

bond_na_send() attempts to insert a VLAN tag in between building and
sending packets of the respective formats. If the slave does not
implement hardware VLAN tag insertion then vlan_put_tag() will mangle
the network-layer header because the Ethernet header is not present at
this point (unlike in bond_arp_send()).
Fix this by adding the tag out-of-line and relying on
dev_hard_start_xmit() to insert it inline if necessary.

A bond may have a mixture of slave devices with and without hardware
VLAN tag insertion capability. Therefore it always claims this
capability and performs software VLAN tag insertion if the slave does
not.
Since commit 7b9c60903714bf0a19d746b228864bad3497284e, this has
also been done by dev_hard_start_xmit(). The result is that VLAN-
tagged skbs are now double-tagged when transmitted through slave
devices without hardware VLAN tag insertion!
Remove the now-redundant logic from bond_dev_queue_xmit().

The first big packets sent to a "low-MTU" client correctly
triggers the creation of a temporary route containing the reduced MTU.
But after the temporary route has expired, new ICMP6 "packet too big"
will be sent, rt6_pmtu_discovery will find the previous EXPIRED route
check that its mtu isn't bigger then in icmp packet and do nothing
before the temporary route will not deleted by gc.
I make the simple experiment:
while :; do
time ( dd if=/dev/zero bs=10K count=1 | ssh hostname dd of=/dev/null ) || break;
done
The "time" reports real 0m0.197s if a temporary route isn't expired, but
it reports real 0m52.837s (!!!!) immediately after a temporare route has
expired.

On suspend, there might be usb wireless drivers which wrongly trigger
the warning in ieee80211_work_work. If an usb driver doesn't have a
suspend hook, the usb stack will disconnect the device. On disconnect,
a mac80211 driver calls ieee80211_unregister_hw, which calls dev_close,
which calls ieee80211_stop, and in the end calls ieee80211_work_purge->
ieee80211_work_work.
The problem is that this call to ieee80211_work_purge comes after
mac80211 is suspended, triggering the warning even when we don't have
work queued in work_list (the expected case when already suspended),
because it always calls ieee80211_work_work.
So, just call ieee80211_work_work in ieee80211_work_purge if we really
have to abort work. This addresses the warning reported at

dev_open will eventually call ieee80211_ibss_join which sets up the
skb used for beacons/probe-responses however it is possible to
receive beacons that attempt to merge before this occurs causing
a null pointer dereference. Check ssid_len as that is the last
thing set in ieee80211_ibss_join.
This occurs quite easily in the presence of adhoc nodes with hidden SSID's

Due to commit 63ce0900 connections initiated through TTYs created with
"rfcomm bind ..." would have security level BT_SECURITY_SDP instead of
BT_SECURITY_LOW. This would cause instant connection failure between any
two SSP capable devices due to the L2CAP connect request to RFCOMM being
sent before authentication has been performed. This patch fixes the
regression by always initializing the DLC security level to
BT_SECURITY_LOW.

The current EEPROM reading code has some layout
assumptions that now turned out to be false with
some newer versions of the EEPROM. Luckily, we
can avoid all such assumptions by using data in
the EEPROM itself, so implement using that.
However, for risk mitigation purposes, keep the
old reading code for current hardware for now.

Or else we can't operate on the right address when the trans length
is greater than 65535.

The user must read N bytes of SPIRF (1 <= N <= 4) that do not exceed the
amount of data in the receive FIFO, so read the SPIRF byte by byte when
the data in receive FIFO is less than 4 bytes.
On Simics, when read N bytes that exceed the amount of data in receive
FIFO, we can't read the data out, that is we can't clear the rx FIFO,
then the CPU will loop on the espi rx interrupt.
