in_slow_tot can't work correctly.
The counter in_slow_tot increase by one when fib_lookup() return successfully

When FS-Cache allocates an object, the following sequence of events can
occur:
-->fscache_alloc_object()
-->cachefiles_alloc_object() [via cache->ops->alloc_object]
<--[returns new object]
-->fscache_attach_object()
<--[failed]
-->cachefiles_put_object() [via cache->ops->put_object]
-->fscache_object_destroy()
-->fscache_objlist_remove()
-->rb_erase() to remove the object from fscache_object_list.
resulting in a crash in the rbtree code.
The problem is that the object is only added to fscache_object_list on
the success path of fscache_attach_object() where it calls
fscache_objlist_add().
So if fscache_attach_object() fails, the object won't have been added to
the objlist rbtree. We do, however, unconditionally try to remove the
object from the tree.
Thanks to NeilBrown for finding this and suggesting this solution.

This has been this way for years, and every time I stumble across it I
lose my lunch. After coming across it for the nth time in the Coverity
results, I had to overcome the bystander effect and do something about
it.
This ignores the 79 column limit in favor of making it look like C
instead of gibberish.
The correct thing to do here would be to lose some of the indentation by
breaking this function up into several smaller ones. I might do that at
some point if I have the stomach to look at this again.
(Also some of those overlong ternary operations would likely be more
readable as regular if's)

Issuing set_termios() from irtty_close() causes kernel Oops for
unplugged usb-serial devices.
Since no other tty_ldisc calls set_termios() on close and no tty driver
seem to check if tty->device_data is NULL or not on entry to set_termios(),
the only solution I can come up with is to remove the irtty_stop_receiver()
call, which only updates termios.

If directory is fragmented, readdir() read its dirfrags one by one.
After reading all dirfrags, the corresponding dentries are sorted in
(frag_t, off) order in the dcache. If dentries of a directory are all
cached, __dcache_readdir() can use the cached dentries to satisfy
readdir syscall. But when checking if a given dentry is after the
position of readdir, __dcache_readdir() compares numerical value of
frag_t directly. This is wrong, it should use ceph_frag_compare().

This is not a buffer overflow in the traditional sense: we don't
overflow any *kernel* buffers, but we do mis-count the amount of data we
copy back to user space for the SYSLOG_ACTION_READ_ALL case.
In particular, if the user buffer is too small to hold everything, and
*if* there is a continuation line at just the right place, we can end up
giving the user more data than he asked for.
The reason is that we first count up the number of bytes all the log
records contains, then we walk the records again until we've skipped the
records at the beginning that won't fit, and then we walk the rest of
the records and copy them to the user space buffer.
And in between that "skip the initial records that won't fit" and the
"copy the records that *will* fit to user space", we reset the 'prev'
variable that contained the record information for the last record not
copied. That meant that when we started copying to user space, we now
had a different character count than what we had originally calculated
in the first record walk-through.
The fix is to simply not clear the 'prev' flags value (in both cases
where we had the same logic: syslog_print_all and kmsg_dump_get_buffer:
the latter is used for pstore-like dumping)

HID core expects the input buffers to be at least of size 4096
(HID_MAX_BUFFER_SIZE). Other sizes will result in buffer-overflows if an
input-report is smaller than advertised. We could, like i2c, compute the
biggest report-size instead of using HID_MAX_BUFFER_SIZE, but this will
blow up if report-descriptors are changed after ->start() has been called.
So lets be safe and just use the biggest buffer we have.
Note that this adds an additional copy to the HIDP input path. If there is
a way to make sure the skb-buf is big enough, we should use that instead.
The best way would be to make hid-core honor the @size argument, though,
that sounds easier than it is. So lets just fix the buffer-overflows for
now and afterwards look for a faster way for all transport drivers.

aggregator_identifier is used to assign unique aggregator identifiers
to aggregators of a bond during device enslaving.
aggregator_identifier is currently a global variable that is zeroed in
bond_3ad_initialize().
This sequence will lead to duplicate aggregator identifiers for eth1 and eth3:
create bond0
change bond0 mode to 802.3ad
enslave eth0 to bond0 //eth0 gets agg id 1
enslave eth1 to bond0 //eth1 gets agg id 2
create bond1
change bond1 mode to 802.3ad
enslave eth2 to bond1 //aggregator_identifier is reset to 0
//eth2 gets agg id 1
enslave eth3 to bond0 //eth3 gets agg id 2
Fix this by making aggregator_identifier private to the bond.

This patch removes a generic hard_header_len check from the usbnet
module that is causing dropped packages under certain circumstances
for devices that send rx packets that cross urb boundaries.
One example is the AX88772B which occasionally send rx packets that
cross urb boundaries where the remaining partial packet is sent with
no hardware header. When the buffer with a partial packet is of less
number of octets than the value of hard_header_len the buffer is
discarded by the usbnet module.
With AX88772B this can be reproduced by using ping with a packet
size between 1965-1976.
The bug has been reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=29082
This patch introduces the following changes:
- Removes the generic hard_header_len check in the rx_complete
function in the usbnet module.
- Introduces a ETH_HLEN check for skbs that are not cloned from
within a rx_fixup callback.
- For safety a hard_header_len check is added to each rx_fixup
callback function that could be affected by this change.
These extra checks could possibly be removed by someone
who has the hardware to test.
- Removes a call to dev_kfree_skb_any() and instead utilizes the
dev->done list to queue skbs for cleanup.
The changes place full responsibility on the rx_fixup callback
functions that clone skbs to only pass valid skbs to the
usbnet_skb_return function.

This bug was reported by Steinar H. Gunderson and was introduced by commit
f7cb8886335d ("sit/gre6: don't try to add the same route two times").
root@morgental:~# ip tunnel add foo mode gre remote 1.2.3.4 ttl 64
root@morgental:~# ip link set foo up mtu 1468
root@morgental:~# ip -6 route show dev foo
fe80::/64 proto kernel metric 256
but after the above commit, no such route shows up.
There is no link local route because dev->dev_addr is 0 (because local ipv4
address is 0), hence no link local address is configured.
In this scenario, the link local address is added manually: 'ip -6 addr add
fe80::1 dev foo' and because prefix is /128, no link local route is added by the
kernel.
Even if the right things to do is to add the link local address with a /64
prefix, we need to restore the previous behavior to avoid breaking userpace.

When computing the CRC on a 2byte variable the order of
the bytes obviously alters the final result. This means
that computing the CRC over the same value on two archs
having different endianess leads to different numbers.
The global and local translation table CRC computation
routine makes this mistake while processing the clients
VIDs. The result is a continuous CRC mismatching between
nodes having different endianess.
Fix this by converting the VID to Network Order before
processing it. This guarantees that every node uses the same
byte order.

Commit 003b5c5719f159f4f4bf97511c4702a0638313dd ("block: Convert drivers
to immutable biovecs") broke dm-mirror due to dm-io breakage.
dm-io had three possible iterators (DM_IO_PAGE_LIST, DM_IO_BVEC,
DM_IO_VMA) that iterate over pages where the I/O should be performed.
The switch to immutable biovecs changed the DM_IO_BVEC iterator to
DM_IO_BIO. Before this change the iterator stored the pointer to a bio
vector in the dpages structure. The iterator incremented the pointer in
the dpages structure as it advanced over the pages. After the immutable
biovecs change, the DM_IO_BIO iterator stores a pointer to the bio in
the dpages structure and uses bio_advance to change the bio as it
advances.
The problem is that the function dispatch_io stores the content of the
dpages structure into the variable old_pages and restores it before
issuing I/O to each of the devices. Before the change, the statement
"*dp = old_pages;" restored the iterator to its starting position.
After the change, struct dpages holds a pointer to the bio, thus the
statement "*dp = old_pages;" doesn't restore the iterator.
Consequently, in the context of dm-mirror: only the first mirror leg is
written correctly, the kernel locks up when trying to write the other
mirror legs because the number of sectors to write in the where->count
variable doesn't match the number of sectors returned by the iterator.
This patch fixes the bug by partially reverting the original patch - it
changes the code so that struct dpages holds a pointer to the bio vector,
so that the statement "*dp = old_pages;" restores the iterator correctly.
The field "context_u" holds the offset from the beginning of the current
bio vector entry, just like the "bio->bi_iter.bi_bvec_done" field.

When completing an overwrite bio, in overwrite_endio(), the associated
migration should not be added to the 'completed_migrations' until the
bio's fields are restored with dm_unhook_bio().
Otherwise, do_worker() can race to process 'completed_migrations' before
dm_unhook_bio() -- so the bio's bi_end_io is incorrect. This is
unlikely to cause any problems given the current code but should be
fixed on the basis of correctness.
Also, the cache's spinlock only needs to be held when manipulating the
'completed_migrations' list -- other changes don't need protection.

For avr32 cross compiler, do not define '__linux__' internally, so it
will cause issue with allmodconfig.

The frame PC value in the unwind code used to just take the saved LR
value and use that. That's incorrect as a stack trace, since it shows
the return path stack, not the call path stack.
In particular, it shows faulty information in case the bl is done as
the very last instruction of one label, since the return point will be
in the next label. That can easily be seen with tail calls to panic(),
which is marked __noreturn and thus doesn't have anything useful after it.
Easiest here is to just correct the unwind code and do a -4, to get the
actual call site for the backtrace instead of the return site.

When the driver tries to access Function Unit 10, the KEF X300A
speakers' firmware apparently locks up, making even PCM streaming
impossible. Work around this by ignoring this FU.
