In __nf_ct_expect_check, the function refresh_timer returns 1
if a matching expectation is found and its timer is successfully
refreshed. This results in nf_ct_expect_related returning 0.
Note that at this point:

- the passed expectation is not inserted in the expectation table
  and its timer was not initialized, since we have refreshed one
  matching/existing expectation.

- nf_ct_expect_alloc uses kmem_cache_alloc, so the expectation
  timer is in some undefined state just after the allocation,
  until it is appropriately initialized.

This can be a problem for the SIP helper during the expectation
addition:

 ...
 if (nf_ct_expect_related(rtp_exp) == 0) {
         if (nf_ct_expect_related(rtcp_exp) != 0)
                 nf_ct_unexpect_related(rtp_exp);
 ...

Note that nf_ct_expect_related(rtp_exp) may return 0 for the timer refresh
case that is detailed above. Then, if nf_ct_unexpect_related(rtcp_exp)
returns != 0, nf_ct_unexpect_related(rtp_exp) is called, which does:

 spin_lock_bh(&nf_conntrack_lock);
 if (del_timer(&exp->timeout)) {
         nf_ct_unlink_expect(exp);
         nf_ct_expect_put(exp);
 }
 spin_unlock_bh(&nf_conntrack_lock);

Note that del_timer always returns false if the timer has been
initialized.  However, the timer was not initialized since setup_timer
was not called, therefore, the expectation timer remains in some
undefined state. If I'm not missing anything, this may lead to the
removal an unexistent expectation.

To fix this, the optimization that allows refreshing an expectation
is removed. Now nf_conntrack_expect_related looks more consistent
to me since it always add the expectation in case that it returns
success.

Thanks to Patrick McHardy for participating in the discussion of
this patch.

Within SIP messages IPv6 addresses are enclosed in square brackets in most
cases, with the exception of the "received=" header parameter. Currently
the helper fails to parse enclosed addresses.

This patch:

- changes the SIP address parsing function to enforce square brackets
  when required, and accept them when not required but present, as
  recommended by RFC 5118.

- adds a new SDP address parsing function that never accepts square
  brackets since SDP doesn't use them.

With these changes, the SIP helper correctly parses all test messages
from RFC 5118 (Session Initiation Protocol (SIP) Torture Test Messages
for Internet Protocol Version 6 (IPv6)).

Driver probe functions are generally __devinit so they will be
discarded after initialization for non-hotplug kernels.
This was found by a new warning after patch 6a228452 "stmmac: Add
device-tree support" adds a new __devinit function that is called
from stmmac_pltfr_probe.

Without this patch, building socfpga_defconfig results in:

The function stmmac_pltfr_probe() references
the function __devinit stmmac_probe_config_dt().
This is often because stmmac_pltfr_probe lacks a __devinit

We allocate memory for 'req' with usb_alloc_urb() and then test
'if (!req || rx_submit(pnd, req, GFP_KERNEL | __GFP_COLD))'.
If we enter that branch due to '!req' then there is no problem. But if
we enter the branch due to 'req' being != 0 and the 'rx_submit()' call
being false, then we'll leak the memory we allocated.
Deal with the leak by always calling 'usb_free_urb(req)' when entering
the branch. If 'req' happens to be 0 then the call is harmless, if it
is not 0 then we free the memory we allocated but don't need.

[Resending again, as the text was corrupted by the email client]

To speed up operations, QFQ internally divides classes into
groups. Which group a class belongs to depends on the ratio between
the maximum packet length and the weight of the class. Unfortunately
the function qfq_change_class lacks the steps for changing the group
of a class when the ratio max_pkt_len/weight of the class changes.

For example, when the last of the following three commands is
executed, the group of class 1:1 is not correctly changed:

tc disc add dev XXX root handle 1: qfq
tc class add dev XXX parent 1: qfq classid 1:1 weight 1
tc class change dev XXX parent 1: classid 1:1 qfq weight 4

Not changing the group of a class does not affect the long-term
bandwidth guaranteed to the class, as the latter is independent of the
maximum packet length, and correctly changes (only) if the weight of
the class changes. In contrast, if the group of the class is not
updated, the class is still guaranteed the short-term bandwidth and
packet delay related to its old group, instead of the guarantees that
it should receive according to its new weight and/or maximum packet
length. This may also break service guarantees for other classes.
This patch adds the missing operations.

Since we really want dst_default_metrics be const to avoid any possible

The first idea of the CAN FD implementation started with a new struct
canfd_frame to be used for both CAN FD frames and legacy CAN frames.
The now mainlined implementation supports both CAN frame types simultaneously
and distinguishes them only by their required sizes: CAN_MTU and CANFD_MTU.

Only the struct canfd_frame contains a flags element which is needed for the
additional CAN FD information. As CAN FD implicitly means that the 'Extened
Data Length' mode is enabled the formerly defined CANFD_EDL bit became
redundant and also confusing as an unset bit would be an error and would
always need to be tested.

This patch removes the obsolete CANFD_EDL bit and clarifies the documentation
for the use of struct canfd_frame and the CAN FD relevant flags.

Some 8086:10c9 NICs have a problem completing the ethtool loopback test.
The result looks like this:

ethtool -t eth1
The test result is FAIL
The test extra info:
Register test  (offline)         0
Eeprom test    (offline)         0
Interrupt test (offline)         0
Loopback test  (offline)         13
Link test   (on/offline)         0

A bisect clearly points to commit a95a0744.
However that seems to only trigger the bug. While adding some printk the
problem disappeared, so this might be a timing issue. After some trial and
error I discovered that adding a small delay just before igb_write_phy_reg()
in igb_integrated_phy_loopback() allows the loopback test to succeed.
I was unable to figure out the root cause so far but I expect it to be
somewhere in the following executing path
igb_integrated_phy_loopback
->igb_write_phy_reg_igp
  ->igb_write_phy_reg_mdic
    ->igb_acquire_phy_82575
      ->igb_acquire_swfw_sync_82575

The problem could only be observed on 8086:10c9 NICs so far and not all
of them show the behaviour. I did not restrict the workaround to this
type of NIC as it should do no harm to other igb NICs.

With the patch below the loopback test succeeded 500 times in a row
using a NIC that would otherwise fail.

A bus trace shows that while executing e1000e_down, TCTL is cleared except
for the PSP bit.  This occurs while in the middle of fetching a TSO packet
since the Tx packet buffer is full at that point. Before the device is
reset, the e1000_watchdog_task starts to run from the middle (it was
apparently pre-empted earlier, although that is not in the trace) and sets
TCTL.EN.  At that point, 82571 transmits the corrupted packet, apparently
because TCTL.MULR was cleared in the middle of fetching a packet, which is
forbidden.

Driver should just clear TCTL.EN in e1000_reset_hw_82571 instead of
clearing the entire register, so as not to change any settings in the
middle of fetching a packet.
