6bfea1984a netfilter: conntrack: remove events flags from userspace exposed file
This patch moves the event flags from linux/netfilter/nf_conntrack_common.h
to net/netfilter/nf_conntrack_ecache.h. This flags are not of any use
from userspace.

274d383b9c netfilter: conntrack: don't report events on module removal
During the module removal there are no possible event listeners
since ctnetlink must be removed before to allow removing
nf_conntrack. This patch removes the event reporting for the
module removal case which is not of any use in the existing code.

f49c857ff2 netfilter: nfnetlink: cleanup for nfnetlink_rcv_msg() function
This patch cleans up the message handling path in two aspects:

 * it uses NLMSG_LENGTH() instead of NLMSG_SPACE() like rtnetlink
does in this case to check if there is enough room for the
Netlink/nfnetlink headers. No need to check for the padding room.

 * it removes a redundant header size checking that has been
 already do at the beginning of the function.

You're right - I got the IOMUX tables wrong and thought UART0 pins are
selected unconditionally. But as it turns out TXD1/RXD1 is for UART0
(mxc_uart_device0), TXD2/RXD2 for UART1 (mxc_uart_device1) etc.

Below is a new patch.

Thanks,

05ad709d04 parport: quickfix the proc registration bug
Ideally we should have a directory of drivers and a link to the 'active'
driver. For now just show the first device which is effectively the existing
semantics without a warning.

This is an update on the original buggy patch that I then forgot to
resubmit. Confusingly it was proposed by Red Hat, written by Etched Pixels
fixed and submitted by Intel ...

179c498ae2 function-graph: only allocate init tasks if it was not already done
When the function graph tracer is enabled, it calls the initialization
needed for the init tasks that would be called on all created tasks.

The problem is that this is called every time the function graph tracer
is enabled, and the ret_stack is allocated for the idle tasks each time.
Thus, the old ret_stack is lost and a memory leak is created.

This is also dangerous because if an interrupt happened on another CPU
with the init task and the ret_stack is replaced, we then lose all the
return pointers for the interrupt, and a crash would take place.

[ Impact: fix memory leak and possible crash due to race ]

50b64e3b77 cifs: fix IPv6 address length check
For IPv6 the userspace mount helper sends an address in the "ip="
option.  This check fails if the length is > 35 characters. I have no
idea where the magic 35 character limit came from, but it's clearly not
enough for IPv6. Fix it by making it use the INET6_ADDRSTRLEN #define.

While we're at it, use the same #define for the address length in SPNEGO
upcalls.

88f627ae39 cciss: fix SCSI device reset handler
Fix the SCSI reset error handler to send a working, properly addressed
reset message to the target device and add code to wait for the target
device to become ready by polling it with Test Unit Ready.

The existing reset code was broken in that it didn't bother to set the
8-byte LUN address to anything besides zero, so the command was addressed
to the controller, which pretended to the driver that the command
succeeded, while doing nothing.  Ages ago I tested this code, but
unbeknownst to me, my test was flawed, and what I thought was a tape drive
getting reset was actually nothing of the sort.  Unfortunately, there is
still lots of Smartarray firmware that doesn't handle doing target resets
right, and this code won't help in those cases, but it also shouldn't make
things worse in those cases than they already are.

874ab9233e netfilter: nf_ct_tcp: TCP simultaneous open support
The patch below adds supporting TCP simultaneous open to conntrack. The
unused LISTEN state is replaced by a new state (SYN_SENT2) denoting the
second SYN sent from the reply direction in the new case. The state table
is updated and the function tcp_in_window is modified to handle
simultaneous open.

The functionality can fairly easily be tested by socat. A sample tcpdump

The RST packet was dropped in the raw table, thus it did not reach
conntrack.  nfnetlink_conntrack is unpatched so it shows the new SYN_SENT2
state as the old unused LISTEN.

With TCP simultaneous open support we satisfy REQ-2 in RFC 5382  ;-) .

Additional minor correction in this patch is that in order to catch
uninitialized reply directions, "td_maxwin == 0" is used instead of
"td_end == 0" because the former can't be true except in uninitialized
state while td_end may accidentally be equal to zero in the mid of a
connection.

bf4e0ed3d0 perf_counter: Remove unused prev_state field
This removes the prev_state field of struct perf_counter since
it is now unused.  It was only used by the cpu migration
counter, which doesn't use it any more.

3f731ca60a perf_counter: Fix cpu migration counter
This fixes the cpu migration software counter to count
correctly even when contexts get swapped from one task to
another.  Previously the cpu migration counts reported by perf
stat were bogus, ranging from negative to several thousand for
a single "lat_ctx 2 8 32" run.  With this patch the cpu
migration count reported for "lat_ctx 2 8 32" is almost always
between 35 and 44.

This fixes the problem by adding a call into the perf_counter
code from set_task_cpu when tasks are migrated.  This enables
us to use the generic swcounter code (with some modifications)
for the cpu migration counter.

This modifies the swcounter code to allow a NULL regs pointer
to be passed in to perf_swcounter_ctx_event() etc.  The cpu
migration counter does this because there isn't necessarily a
pt_regs struct for the task available.  In this case, the
counter will not have interrupt capability - but the migration
counter didn't have interrupt capability before, so this is no
loss.

f38b082081 perf_counter: Initialize per-cpu context earlier on cpu up
This arranges for perf_counter's notifier for cpu hotplug
operations to be called earlier than the migration notifier in
sched.c by increasing its priority to 20, compared to the 10
for the migration notifier.  The reason for doing this is that
a subsequent commit to convert the cpu migration counter to use
the generic swcounter infrastructure will add a call into the
perf_counter subsystem when tasks get migrated.  Therefore the
perf_counter subsystem needs a chance to initialize its per-cpu
data for the new cpu before it can get called from the
migration code.

This also adds a comment to the migration notifier noting that
its priority needs to be lower than that of the perf_counter
notifier.

bafeee5b1f ALSA: snd_usb_caiaq: give better shortname
If not passed as module option, provide an own card ID with the newly
introduced snd_set_card_id() call.

This will prevent ALSA from calling choose_default_name() which only
takes the last part of a name containing whitespaces. This for example
caused 'Audio 4 DJ' to be shortened to 'DJ', which was not very
descriptive.

The implementation now takes the short name and removes all whitespaces
from it which is much nicer.

10a8ebbb08 ALSA: Core - add snd_card_set_id() function
Introduce snd_card_set_id() function to allow lowlevel drivers to set
default identification name for card slot. The function checks also
for identification name collisions and tries to create unique name.

Also, the snd_card_create() function is simplified, because this new
function is used. As bonus, proper name collision checks are evaluated
at the card create time.
