If udp_recvmsg() constantly releases sk_rmem_alloc
for every read packet, it gives opportunity for
producers to immediately grab spinlocks and desperatly
try adding another packet, causing false sharing.We can add a simple heuristic to give the signal
by batches of ~25 % of the queue capacity.This patch considerably increases performance under
flood by about 50 %, since the thread draining the queue
is no longer slowed by false sharing.Signed-off-by: Eric Dumazet

Pull libnvdimm fixes from Dan Williams:
"Several fixes to the DSM (ACPI device specific method) marshaling

successful execution of ARS commands enables the platform to

When mac80211 abandons an association attempt, it may free
all the data structures, but inform cfg80211 and userspace
about it only by sending the deauth frame it received, in
which case cfg80211 has no link to the BSS struct that was
used and will not cfg80211_unhold_bss() it.Fix this by providing a way to inform cfg80211 of this with
the BSS entry passed, so that it can clean up properly, and
use this ability in the appropriate places in mac80211.This isn't ideal: some code is more or less duplicated and
tracing is missing. However, it's a fairly small change and
it's thus easier to backport - cleanups can come later.Cc: stable@vger.kernel.org

NL80211_ATTR_MAC was used to set both the specific BSSID to be scanned
and the random MAC address to be used when privacy is enabled. When both
the features are enabled, both the BSSID and the local MAC address were
getting same value causing Probe Request frames to go with unintended
DA. Hence, this has been fixed by using a different NL80211_ATTR_BSSID
attribute to set the specific BSSID (which was the more recent addition
in cfg80211) for a scan.Backwards compatibility with old userspace software is maintained to
some extent by allowing NL80211_ATTR_MAC to be used to set the specific
BSSID when scanning without enabling random MAC address use.Scanning with random source MAC address was introduced by commit
ad2b26abc157 ("cfg80211: allow drivers to support random MAC addresses
for scan") and the issue was introduced with the addition of the second
user for the same attribute in commit 818965d39177 ("cfg80211: Allow a
scan request for a specific BSSID").Fixes: 818965d39177 ("cfg80211: Allow a scan request for a specific BSSID")

done by adding a new XDP helper bpf_xdp_adjust_head().It also renames bpf_helper_changes_skb_data() to
bpf_helper_changes_pkt_data() to better reflect

Under UDP flood, many softirq producers try to add packets to
UDP receive queue, and one user thread is burning one cpu trying
to dequeue packets as fast as possible.Two parts of the per packet cost are :
- copying payload from kernel space to user space,
- freeing memory pieces associated with skb.If socket is under pressure, softirq handler(s) can try to pull in
skb->head the payload of the packet if it fits.Meaning the softirq handler(s) can free/reuse the page fragment
immediately, instead of letting udp_recvmsg() do this hundreds of usec
later, possibly from another node.Additional gains :
- We reduce skb->truesize and thus can store more packets per SO_RCVBUF
- We avoid cache line misses at copyout() time and consume_skb() time,
and avoid one put_page() with potential alien freeing on NUMA hosts.This comes at the cost of a copy, bounded to available tail room, which
is usually small. (We might have to fix GRO_MAX_HEAD which looks bigger
than necessary)This patch gave me about 5 % increase in throughput in my tests.
skb_condense() helper could probably used in other contexts.

====================
Netfilter/IPVS updates for net-nextThe following patchset contains a large Netfilter update for net-next,
to summarise:1) Add support for stateful objects. This series provides a nf_tables
native alternative to the extended accounting infrastructure for
nf_tables. Two initial stateful objects are supported: counters and
quotas. Objects are identified by a user-defined name, you can fetch
and reset them anytime. You can also use a maps to allow fast lookups
using any arbitrary key combination. More info at:http://marc.info/?l=netfilter-devel&m=148029128323837&w=2
2) On-demand registration of nf_conntrack and defrag hooks per netns.
Register nf_conntrack hooks if we have a stateful ruleset, ie.
state-based filtering or NAT. The new nf_conntrack_default_on sysctl
enables this from newly created netnamespaces. Default behaviour is not
modified. Patches from Florian Westphal.3) Allocate 4k chunks and then use these for x_tables counter allocation
requests, this improves ruleset load time and also datapath ruleset
evaluation, patches from Florian Westphal.4) Add support for ebpf to the existing x_tables bpf extension.
From Willem de Bruijn.5) Update layer 4 checksum if any of the pseudoheader fields is updated.
This provides a limited form of 1:1 stateless NAT that make sense in
specific scenario, eg. load balancing.6) Add support to flush sets in nf_tables. This series comes with a new
set->ops->deactivate_one() indirection given that we have to walk
over the list of set elements, then deactivate them one by one.
The existing set->ops->deactivate() performs an element lookup that
we don't need.7) Two patches to avoid cloning packets, thus speed up packet forwarding
via nft_fwd from ingress. From Florian Westphal.8) Two IPVS patches via Simon Horman: Decrement ttl in all modes to
prevent infinite loops, patch from Dwip Banerjee. And one minor
refactoring from Gao feng.9) Revisit recent log support for nf_tables netdev families: One patch
to ensure that we correctly handle non-ethernet packets. Another
patch to add missing logger definition for netdev. Patches from
Liping Zhang.10) Three patches for nft_fib, one to address insufficient register
initialization and another to solve incorrect (although harmless)
byteswap operation. Moreover update xt_rpfilter and nft_fib to match
lbcast packets with zeronet as source, eg. DHCP Discover packets
(0.0.0.0 -> 255.255.255.255). Also from Liping Zhang.11) Built-in DCCP, SCTP and UDPlite conntrack and NAT support, from
Davide Caratti. While DCCP is rather hopeless lately, and UDPlite has
been broken in many-cast mode for some little time, let's give them a
chance by placing them at the same level as other existing protocols.
Thus, users don't explicitly have to modprobe support for this and
NAT rules work for them. Some people point to the lack of support in
SOHO Linux-based routers that make deployment of new protocols harder.
I guess other middleboxes outthere on the Internet are also to blame.
Anyway, let's see if this has any impact in the midrun.12) Skip software SCTP software checksum calculation if the NIC comes
with SCTP checksum offload support. From Davide Caratti.13) Initial core factoring to prepare conversion to hook array. Three
patches from Aaron Conole.14) Gao Feng made a wrong conversion to switch in the xt_multiport
extension in a patch coming in the previous batch. Fix it in this
batch.15) Get vmalloc call in sync with kmalloc flags to avoid a warning
and likely OOM killer intervention from x_tables. From Marcelo
Ricardo Leitner.16) Update Arturo Borrero's email address in all source code headers.

This reverts commit 8ab2ae655bfe384335c5b6b0d6041e0ddce26b00.
I loved that commit because of how it explained what the problem with
newer versions of binutils were, but the actual patch itself turns out
to not work very well.It has two problems:
- a zero CRC value isn't actually right. It happens to work for the
case where both sides of the equation fail at giving the symbol a
crc, but there are cases where the users of the exported symbol get
the right crc (due to seeing the C declarations), but the actual
exporting itself does not (due to the whole weak asm symbol issue).So then the module load fails after all - we did have a crc for the
symbol, but we couldn't match it with the loaded module.- it seems that the alpha assembler has special semantics for the
'.set' directive, and on alpha it doesn't actually set the value of
the specified symbol at all, it is instead used to set various
assembly modes (eg ".set noat" and ".set noreorder").So using ".set" to set the symbol value would just cause build
failures on alpha.I'm sure we'll find some other workaround for these issues (hopefully
that involves getting rid of modversions entirely some day, but people
are also talking about just using smarter tools). But for now we'll
just fall back on commit faaae2a58143 ("Re-enable CONFIG_MODVERSIONS in
a slightly weaker form") that just let's a missing crc through.Reported-by: Jan Stancek

Paolo noticed a cache line miss in UDP recvmsg() to access
sk_rxhash, sharing a cache line with sk_drops.sk_drops might be heavily incremented by cpus handling a flood targeting
this socket.We might place sk_drops on a separate cache line, but lets try
to avoid wasting 64 bytes per socket just for this, since we have
other bottlenecks to take care of.sock_rps_record_flow() should only access sk_rxhash for connected
flows.Testing sk_state for TCP_ESTABLISHED covers most of the cases for
connected sockets, for a zero cost, since system calls using
sock_rps_record_flow() also access sk->sk_prot which is on the
same cache line.A follow up patch will provide a static_key (Jump Label) since most
hosts do not even use RFS.Signed-off-by: Eric Dumazet

Given ambiguities in the ACPI 6.1 definition of the "Output (Size)"
field of the ARS (Address Range Scrub) Status command, a firmware
implementation may in practice return 0, 4, or 8 to indicate that there
is no output payload to process.The specification states "Size of Output Buffer in bytes, including this
field.". However, 'Output Buffer' is also the name of the entire
payload, and earlier in the specification it states "Max Query ARS
Status Output Buffer Size: Maximum size of buffer (including the Status
and Extended Status fields)".Without this fix if the BIOS happens to return 0 it causes memory
corruption as evidenced by this result from the acpi_nfit_ctl() unit
