It's possible to isolate some freepages in a pageblock and then fail
split_free_page() due to the low watermark check. In this case, we hit
VM_BUG_ON() because the freeing scanner terminated early without a
contended lock or enough freepages.
This should never have been a VM_BUG_ON() since it's not a fatal
condition. It should have been a VM_WARN_ON() at best, or even handled
gracefully.
Regardless, we need to terminate anytime the full pageblock scan was not
done. The logic belongs in isolate_freepages_block(), so handle its
state gracefully by terminating the pageblock loop and making a note to
restart at the same pageblock next time since it was not possible to
complete the scan this time.

not incrementing the refcount of the of_node which results in the node

We can't sleep with RCU read lock held, but we need to do potentially
blocking stuff to namespace queues when iterating the list. This patch
removes the RCU locking and holds a mutex instead.
To prevent deadlocks, this patch removes holding the mutex during
namespace scanning and removal. The unlocked namespace scanning is made
safe by holding a reference to the namespace being scanned.
List iteration that does IO has to be unlocked to allow error recovery.
The caller must ensure the list can not be manipulated during such an
event, so this patch adds a comment explaining this requirement to the
only function that iterates an unlocked list. All callers currently
meet this requirement, so no further changes required.
List iterations that do not do IO can safely use the lock since it couldn't
block recovery from missing forced IO completions.

limit sk_filter trim to payload
Sockets can apply a filter to incoming packets to drop or trim them.
Fix two codepaths that call skb_pull/__skb_pull after sk_filter
without checking for packet length.
Reading beyond skb->tail after trimming happens in more codepaths, but
safety of reading in the linear segment is based on minimum allocation
size (MAX_HEADER, GRO_MAX_HEAD, ..).

Dccp verifies packet integrity, including length, at initial rcv in
dccp_invalid_packet, later pulls headers in dccp_enqueue_skb.
A call to sk_filter in-between can cause __skb_pull to wrap skb->len.
skb_copy_datagram_msg interprets this as a negative value, so
(correctly) fails with EFAULT. The negative length is reported in
ioctl SIOCINQ or possibly in a DCCP_WARN in dccp_close.
Introduce an sk_receive_skb variant that caps how small a filter
program can trim packets, and call this in dccp with the header
length. Excessively trimmed packets are now processed normally and
queued for reception as 0B payloads.

Sockets can have a filter program attached that drops or trims

Rose requires data packets to have at least ROSE_MIN_LEN bytes. It
verifies this on arrival in rose_route_frame and unconditionally pulls
the bytes in rose_recvmsg. The filter can trim packets to below this
value in-between, causing pull to fail, leaving the partial header at
the time of skb_copy_datagram_msg.

by introducing sk_filter_trim_cap and call this for rose packets.

The bug is the following: the cpuhp_bp_states[] array is cut short when

and happily scribble outside of the array bounds...
We need to store them in case that the state is unregistered so we can invoke

This commit looks like a cleanup but in fact by causing the core to go
down some simplified code paths for noop regulators it avoids a boot
time crash for msm8974 platforms which was introduced in v4.7. It has
been in -next for a while, the issues in mainline for these platforms
weren't flagged up to me until yesterday (I think it took some time to
figure out what was going wrong).

Netfilter/IPVS fixes for net
The following patchset contains Netfilter/IPVS fixes for your net tree.
they are:
1) Fix leak in the error path of nft_expr_init(), from Liping Zhang.
2) Tracing from nf_tables cannot be disabled, also from Zhang.
3) Fix an integer overflow on 32bit archs when setting the number of
hashtable buckets, from Florian Westphal.
4) Fix configuration of ipvs sync in backup mode with IPv6 address,
from Quentin Armitage via Simon Horman.
5) Fix incorrect timeout calculation in nft_ct NFT_CT_EXPIRATION,
from Florian Westphal.
6) Skip clash resolution in conntrack insertion races if NAT is in
place.

Add the missing port_xmit_wait counter. This counter is displayed through
some tools like perfquery but is not available via sysfs.
For the PORT_PMA_ATTR macro the _counter field is set to zero
allowing us to specify the offset directly like with PORT_PMA_ATTR_EXT

The critical section should protect only the list traversal
and dd->asic_data modification, not the memory allocation.
The fix pulls the allocation out of the critical section.

There are several computatations of the sc in the
ud receive routine.
Besides the code duplication, all are wrong when the
sc is greater than 15. In that case the code incorrectly
or's a 1 into the computed sc instead of 1 shifted left
by 4.
Fix precomputed sc5 by using an already implemented routine
hdr2sc() and deleting flawed duplicated code.

The clash resolution is not easy to apply if the NAT table is
registered. Even if no NAT rules are installed, the nul-binding ensures
that a unique tuple is used, thus, the packet that loses race gets a
different source port number, as described by:
http://marc.info/?l=netfilter-devel&m=146818011604484&w=2
Clash resolution with NAT is also problematic if addresses/port range
ports are used since the conntrack that wins race may describe a
different mangling that we may have earlier applied to the packet via
nf_nat_setup_info().
