Micron flashes do not support 16 bit writes on the Status Register.
According to micron datasheets, when using the Write Status Register
(01h) command, the chip select should be driven LOW and held LOW until
the eighth bit of the last data byte has been latched in, after which
it must be driven HIGH. If CS is not driven HIGH, the command is not
executed, flag status register error bits are not set, and the write enable
latch remains set to 1. This fixes the lock operations on micron flashes.

We are currently using nand_soft_waitrdy to poll the status of the NAND
flash. FMC2 enables the wait feature bit (this feature is mandatory for
the sequencer mode). By enabling this feature, we can't poll the status
of the NAND flash, the read status command is stucked in FMC2 pipeline
until R/B# signal is high, and locks the CPU bus.
To avoid to lock the CPU bus, we poll FMC2 ISR register. This register
reports the status of the R/B# signal.

Commit 85a8ce62 ("block: add bio_truncate to fix guard_bio_eod")
adds bio_truncate() for handling bio EOD. However, bio_truncate()
doesn't use the passed 'op' parameter from guard_bio_eod's callers.

So bio_trunacate() may retrieve wrong 'op', and zering pages may
not be done for READ bio.

Fixes this issue by moving guard_bio_eod() after bio_set_op_attrs()
in submit_bh_wbc() so that bio_truncate() can always retrieve correct
op info.

Meantime remove the 'op' parameter from guard_bio_eod() because it isn't
used any more.

In my attempt to fix a memory leak, I introduced a double-free in the
pstore error path. Instead of trying to manage the allocation lifetime
between persistent_ram_new() and its callers, adjust the logic so
persistent_ram_new() always takes a kstrdup() copy, and leaves the
caller's allocation lifetime up to the caller. Therefore callers are
_always_ responsible for freeing their label. Before, it only needed
freeing when the prz itself failed to allocate, and not in any of the
other prz failure cases, which callers would have no visibility into,
which is the root design problem that lead to both the leak and now
double-free bugs.

The current 'tipc_wait_for_connect()' function does a wait-loop for the
condition 'sk->sk_state != TIPC_CONNECTING' to conclude if the socket
connecting has done. However, when the condition is met, it returns '0'
even in the case the connecting is actually failed, the socket state is
set to 'TIPC_DISCONNECTING' (e.g. when the server socket has closed..).
This results in a wrong return code for the 'connect()' call from user,
making it believe that the connection is established and go ahead with
building, sending a message, etc. but finally failed e.g. '-EPIPE'.

This commit fixes the issue by changing the wait condition to the
'tipc_sk_connected(sk)', so the function will return '0' only when the
connection is really established. Otherwise, either the socket 'sk_err'
if any or '-ETIMEDOUT'/'-EINTR' will be returned correspondingly.

When a socket is suddenly shutdown or released, it will reject all the
unreceived messages in its receive queue. This applies to a connected
socket too, whereas there is only one 'FIN' message required to be sent
back to its peer in this case.

In case there are many messages in the queue and/or some connections
with such messages are shutdown at the same time, the link layer will
easily get overflowed at the 'TIPC_SYSTEM_IMPORTANCE' backlog level
because of the message rejections. As a result, the link will be taken
down. Moreover, immediately when the link is re-established, the socket
layer can continue to reject the messages and the same issue happens...

The commit refactors the '__tipc_shutdown()' function to only send one
'FIN' in the situation mentioned above. For the connectionless case, it
is unavoidable but usually there is no rejections for such socket
messages because they are 'dest-droppable' by default.

In addition, the new code makes the other socket states clear
(e.g.'TIPC_LISTEN') and treats as a separate case to avoid misbehaving.

Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Missing netns context in arp_tables, from Florian Westphal.

2) Underflow in flowtable reference counter, from wenxu.

3) Fix incorrect ethernet destination address in flowtable offload,
   from wenxu.

4) Check for status of neighbour entry, from wenxu.

5) Fix NAT port mangling, from wenxu.

6) Unbind callbacks from destroy path to cleanup hardware properly
   on flowtable removal.

7) Fix missing casting statistics timestamp, add nf_flowtable_time_stamp
   and use it.

8) NULL pointer exception when timeout argument is null in conntrack
   dccp and sctp protocol helpers, from Florian Westphal.

9) Possible nul-dereference in ipset with IPSET_ATTR_LINENO, also from
   Florian.

The set uadt functions assume lineno is never NULL, but it is in
case of ip_set_utest().

syzkaller managed to generate a netlink message that calls this with
LINENO attr present:

pass a dummy lineno storage, its easier than patching all set
implementations.

This seems to be a day-0 bug.

The timeout pointer can be NULL which means we should modify the
per-nets timeout instead.

All do this, except sctp and dccp which instead give:

With -O3, gcc has found an actual unintialized variable stored
into an mmio register in two instances:

   writel(dma[i*2+1],eni_dev->rx_dma+dma_wr*8+4);
             ^

Change the code to always write zeroes instead.
