commit be9f4a44e7d41cee (ipv4: tcp: remove per net tcp_sock) added a
selinux regression, reported and bisected by John Stultz

selinux_ip_postroute_compat() expect to find a valid sk->sk_security
pointer, but this field is NULL for unicast_sock

It turns out that unicast_sock are really temporary stuff to be able
to reuse  part of IP stack (ip_append_data()/ip_push_pending_frames())

Fact is that frames sent by ip_send_unicast_reply() should be orphaned
to not fool LSM.

Note IPv6 never had this problem, as tcp_v6_send_response() doesnt use a
fake socket at all. I'll probably implement tcp_v4_send_response() to
remove these unicast_sock in linux-3.7

sched: add missing group change to qfq_change_class

[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.

net: fib: fix incorrect call_rcu_bh()

After IP route cache removal, I believe rcu_bh() has very little use and
we should remove this RCU variant, since it adds some cycles in fast
path.

Anyway, the call_rcu_bh() use in fib_true is obviously wrong, since
some users only assert rcu_read_lock().

canfd: remove redundant CAN FD flag

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

igb: add delay to allow igb loopback test to succeed on 8086:10c9

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 a95a07445ee97a2fef65befafbadcc30ca1bd145.
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.

for the PSP bit.  This occurs while in the middle of fetching a TSO packet

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

Artem Bityutskiy [Wed, 25 Jul 2012 15:11:59 +0000 (18:11 +0300)]
vfs: kill write_super and sync_supers

Finally we can kill the 'sync_supers' kernel thread along with the
'->write_super()' superblock operation because all the users are gone.
Now every file-system is supposed to self-manage own superblock and
its dirty state.

The nice thing about killing this thread is that it improves power management.
Indeed, 'sync_supers' is a source of monotonic system wake-ups - it woke up
every 5 seconds no matter what - even if there were no dirty superblocks and
even if there were no file-systems using this service (e.g., btrfs and
journalled ext4 do not need it). So it was wasting power most of the time. And
because the thread was in the core of the kernel, all systems had to have it.
So I am quite happy to make it go away.

Interestingly, this thread is a left-over from the pdflush kernel thread which
was a self-forking kernel thread responsible for all the write-back in old
Linux kernels. It was turned into per-block device BDI threads, and
'sync_supers' was a left-over. Thus, R.I.P, pdflush as well.
