We did this for IPv4 in b49d3c1e1c "net: ipmr: limit MRT_TABLE
identifiers" but we need to do it for IPv6 as well. On IPv6 the name
is "pim6reg" instead of "pimreg" so there is one less digit allowed.
The strcpy() is in ip6mr_reg_vif().

commit 9992c2e (net: cdc_ncm: workaround for missing CDC Union)
added code to lookup an IAD for the interface we are probing.
This is redundant. The USB core has already done the lookup
and saved the result in the USB interface struct. Use that
instead.

There are more types of IP addresses that may appear in ARP packets that we

John W. Linville says:
====================
This is a batch of fixes intende for the 3.8 stream.
Regarding the iwlwifi bits, Johannes says this:
"Please pull to get a single fix from Emmanuel for a bug I introduced due
to misunderstanding the code."
Regarding the mac80211 bits, Johannes says this:
"I have a few small fixes for you:
* some mesh frames would cause encryption warnings -- fixes from Bob
* scanning would pretty much break an association if we transmitted
anything to the AP while scanning -- fix from Stanislaw
* mode injection was broken by channel contexts -- fix from Felix
* FT roaming was broken: hardware crypto would get disabled by it"
Along with that, a handful of other fixes confined to specific drivers.
Avinash Patil fixes a typo in a NULL check in mwifiex.
Larry Finger fixes a build warning in rtlwifi. Seems safe...
Stanislaw Gruszka fixes iwlegacy to prevent microcode errors when
switching from IBSS mode to STA mode.
Felix Fietkau provides a trio of ath9k fixes related to proper tuning.
Please let me know if there are problems!

Ben Greear reported crashes in ip_rcv_finish() on a stress
test involving many macvlans.
We tracked the bug to a dst use after free. ip_rcv_finish()
was calling dst->input() and got garbage for dst->input value.
It appears the bug is in loopback driver, lacking
a skb_dst_force() before calling netif_rx().
As a result, a non refcounted dst, normally protected by a
RCU read_lock section, was escaping this section and could
be freed before the packet being processed.

An issue has been reported where the PMIC either locks up or fails to
respond following a system Reset. This could result in a second write
in which the bus writes the current content of the write buffer to address
of the last I2C access.
The failure case is where this unwanted write transfers incorrect data to
a critical register.
This patch fixes this issue to by following any read or write with a dummy read
to a safe register address. A safe register address is one where the contents
will not affect the operation of the system.

btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the
first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/
btrfs_queue_worker for this inode, and then it locks the list, checks the
head of the list again. But because we don't delete the first inode that it
deals with before, it will fetch the same inode. As a result, this function
allocates a huge amount of btrfs_delalloc_work structures, and OOM happens.
Fix this problem by splice this delalloc list.

First, though the current transaction->aborted check can stop the commit early
and avoid unnecessary operations, it is too early, and some transaction handles
don't end, those handles may set transaction->aborted after the check.
Second, when we commit the transaction, we will wake up some worker threads to
flush the space cache and inode cache. Those threads also allocate some transaction
handles and may set transaction->aborted if some serious error happens.
So we need more check for ->aborted when committing the transaction. Fix it.

I noticed a WARN_ON going off when adding csums because we were going over
the amount of csum bytes that should have been allowed for an ordered
extent. This is a leftover from when we used to hold the csums privately
for direct io, but now we use the normal ordered sum stuff so we need to
make sure and check if we've moved on to another extent so that the csums
are added to the right extent. Without this we could end up with csums for
bytenrs that don't have extents to cover them yet. Thanks,

For compressed extents, the range of checksum is covered by disk length,
and the disk length is different with ram length, so we need to use disk
length instead to get us the right checksum.

A user reported a BUG_ON(ret) that occured during tree log replay. Ret was
-EAGAIN, so what I think happened is that we removed an extent that covered
a bitmap entry and an extent entry. We remove the part from the bitmap and
return -EAGAIN and then search for the next piece we want to remove, which
happens to be an entire extent entry, so we just free the sucker and return.
The problem is ret is still set to -EAGAIN so we trip the BUG_ON(). The
user used btrfs-zero-log so I'm not 100% sure this is what happened so I've
added a WARN_ON() to catch the other possibility. Thanks,

We drop the extent map tree lock while we're logging extents, so somebody
could come in and merge another extent into this one and screw up our
logging, or they could even remove us from the list which would keep us from
logging the extent or freeing our ref on it, so we need to make sure to not
clear LOGGING until after the extent is logged, and then we can merge it to
adjacent extents. Thanks,

in such case it wasn't initialized correctly - master site
