alx: prepare interrupt functions for multiple queues
Extend the interrupt bringup code and the interrupt handler for msi-x
interrupts in order to handle multiple queues.
We must change the poll function because with multiple queues it is possible
that an alx_napi structure has only a tx or only a rx queue pointer.

====================
dpaa_eth: Add the QorIQ DPAA Ethernet driver
This patch series adds the Ethernet driver for the Freescale
QorIQ Data Path Acceleration Architecture (DPAA).
This version includes changes following the feedback received
on previous versions from Eric Dumazet, Bob Cochran, Joe Perches,
Paul Bolle, Joakim Tjernlund, Scott Wood, David Miller - thank you.
Together with the driver a managed version of alloc_percpu
is provided that simplifies the release of per-CPU memory.
The Freescale DPAA architecture consists in a series of hardware
blocks that support the Ethernet connectivity. The Ethernet driver
depends upon the following drivers that are currently in the Linux
kernel:
- Peripheral Access Memory Unit (PAMU)
drivers/iommu/fsl_*
- Frame Manager (FMan) added in v4.4
drivers/net/ethernet/freescale/fman
- Queue Manager (QMan), Buffer Manager (BMan) added in v4.9-rc1
drivers/soc/fsl/qbman
dpaa_eth interfaces mapping to FMan MACs:
dpaa_eth /eth0\ ... /ethN\
driver | | | |
------------- ---- ----------- ---- -------------
-Ports / Tx Rx \ ... / Tx Rx \
FMan | | | |
-MACs | MAC0 | | MACN |

where the acronyms used above (and in the code) are:
DPAA = Data Path Acceleration Architecture
FMan = DPAA Frame Manager
QMan = DPAA Queue Manager
BMan = DPAA Buffers Manager
QMI = QMan interface in FMan
BMI = BMan interface in FMan
FMan SP = FMan Storage Profiles
MURAM = Multi-user RAM in FMan
FQ = QMan Frame Queue
Rx Dfl FQ = default reception FQ
Rx Err FQ = Rx error frames FQ
Tx Cnf FQ = Tx confirmation FQ
Tx FQs = transmission frame queues
dtsec = datapath three speed Ethernet controller (10/100/1000 Mbps)
tgec = ten gigabit Ethernet controller (10 Gbps)
memac = multirate Ethernet MAC (10/100/1000/10000)
Changes from v7:
- remove the debug option to use a common buffer pool for all the
interfaces
Changed from v6:
- fixed an issue on an error path in dpaa_set_mac_address()
- removed NDO operation definitions that were not needed
- sorted the local variable declarations
- cleaned up a few checkpatch checks
- removed friendly network interface naming code
Changes from v5:
- adapt to the latest Q/BMan drivers API
- use build_skb() on Rx path instead of buffer pool refill path
- proper support for multiple buffer pools
- align function, variable names, code cleanup
- driver file structure cleanup
Changes from v4:
- addressed feedback from Scott Wood and Joe Perches
- fixed spelling
- fixed leak of uninitialized stack to userspace
- fix prints
- replace raw_cpu_ptr() with this_cpu_ptr()
- remove _s from the end of structure names
- remove underscores at start of functions, goto labels
- remove likely in error paths
- use container_of() instead of open casts
- remove priv from the driver name
- move return type on same line with function name
- drop DPA_READ_SKB_PTR/DPA_WRITE_SKB_PTR
Changes from v3:
- removed bogus delay and comment in .ndo_stop implementation
- addressed minor issues reported by David Miller

net: ethernet: sun4i-emac: Read rxhdr in CPU byte-order
The EMAC EMAC_RX_IO_DATA_REG data register is dual-purpose: On one hand
it is used to move actual packet data off the wire. This will be in
wire-format and accepted as such by higher layers such as IP. Therefore
it is correctly read as-is (i.e. raw) using readsl.
On the other hand it provides metadata about incoming transfers to the
driver such as length and checksum validation status. This data is
little-endian, always and it is interpreted by the driver. Therefore it
needs to be swapped to CPU endianness to make sense to the driver. This
is already done for the "receive header" but not rxhdr.

bpf: Add tests for the LRU bpf_htab
This patch has some unit tests and a test_lru_dist.
The test_lru_dist reads in the numeric keys from a file.
The files used here are generated by a modified fio-genzipf tool
originated from the fio test suit. The sample data file can be
found here: https://github.com/iamkafai/bpf-lru
The zipf.* data files have 100k numeric keys and the key is also
ranged from 1 to 100k.
The test_lru_dist outputs the number of unique keys (nr_unique).
F.e. The following means, 61239 of them is unique out of 100k keys.
nr_misses means it cannot be found in the LRU map, so nr_misses
must be >= nr_unique. test_lru_dist also simulates a perfect LRU
map as a comparison:

bpf: Add percpu LRU list
Instead of having a common LRU list, this patch allows a
percpu LRU list which can be selected by specifying a map
attribute. The map attribute will be added in the later
patch.
While the common use case for LRU is #reads >> #updates,
percpu LRU list allows bpf prog to absorb unusual #updates

could be under attack).
Each percpu LRU is isolated from each other. The LRU nodes (including
free nodes) cannot be moved across different LRU Lists.

bpf: LRU List
Introduce bpf_lru_list which will provide LRU capability to
the bpf_htab in the later patch.
* General Thoughts:
1. Target use case. Read is more often than update.
(i.e. bpf_lookup_elem() is more often than bpf_update_elem()).
If bpf_prog does a bpf_lookup_elem() first and then an in-place
update, it still counts as a read operation to the LRU list concern.
2. It may be useful to think of it as a LRU cache
3. Optimize the read case
3.1 No lock in read case
3.2 The LRU maintenance is only done during bpf_update_elem()
4. If there is a percpu LRU list, it will lose the system-wise LRU
property. A completely isolated percpu LRU list has the best
performance but the memory utilization is not ideal considering
the work load may be imbalance.
5. Hence, this patch starts the LRU implementation with a global LRU
list with batched operations before accessing the global LRU list.
As a LRU cache, #read >> #update/#insert operations, it will work well.
6. There is a local list (for each cpu) which is named
'struct bpf_lru_locallist'. This local list is not used to sort
the LRU property. Instead, the local list is to batch enough
operations before acquiring the lock of the global LRU list. More
details on this later.
7. In the later patch, it allows a percpu LRU list by specifying a
map-attribute for scalability reason and for use cases that need to
prepare for the worst (and pathological) case like DoS attack.
The percpu LRU list is completely isolated from each other and the
LRU nodes (including free nodes) cannot be moved across the list. The
following description is for the global LRU list but mostly applicable
to the percpu LRU list also.
* Global LRU List:
1. It has three sub-lists: active-list, inactive-list and free-list.
2. The two list idea, active and inactive, is borrowed from the
page cache.
3. All nodes are pre-allocated and all sit at the free-list (of the
global LRU list) at the beginning. The pre-allocation reasoning
is similar to the existing BPF_MAP_TYPE_HASH. However,
opting-out prealloc (BPF_F_NO_PREALLOC) is not supported in
the LRU map.
* Active/Inactive List (of the global LRU list):
1. The active list, as its name says it, maintains the active set of
the nodes. We can think of it as the working set or more frequently
accessed nodes. The access frequency is approximated by a ref-bit.
The ref-bit is set during the bpf_lookup_elem().
2. The inactive list, as its name also says it, maintains a less
active set of nodes. They are the candidates to be removed
from the bpf_htab when we are running out of free nodes.
3. The ordering of these two lists is acting as a rough clock.
The tail of the inactive list is the older nodes and
should be released first if the bpf_htab needs free element.
* Rotating the Active/Inactive List (of the global LRU list):
1. It is the basic operation to maintain the LRU property of
the global list.
2. The active list is only rotated when the inactive list is running
low. This idea is similar to the current page cache.
Inactive running low is currently defined as
"# of inactive < # of active".
3. The active list rotation always starts from the tail. It moves
node without ref-bit set to the head of the inactive list.
It moves node with ref-bit set back to the head of the active
list and then clears its ref-bit.
4. The inactive rotation is pretty simply.
It walks the inactive list and moves the nodes back to the head of
active list if its ref-bit is set. The ref-bit is cleared after moving
to the active list.
If the node does not have ref-bit set, it just leave it as it is
because it is already in the inactive list.
* Shrinking the Inactive List (of the global LRU list):
1. Shrinking is the operation to get free nodes when the bpf_htab is
full.
2. It usually only shrinks the inactive list to get free nodes.
3. During shrinking, it will walk the inactive list from the tail,
delete the nodes without ref-bit set from bpf_htab.
4. If no free node found after step (3), it will forcefully get
one node from the tail of inactive or active list. Forcefully is
in the sense that it ignores the ref-bit.
* Local List:
1. Each CPU has a 'struct bpf_lru_locallist'. The purpose is to
batch enough operations before acquiring the lock of the
global LRU.
2. A local list has two sub-lists, free-list and pending-list.
3. During bpf_update_elem(), it will try to get from the free-list
of (the current CPU local list).
4. If the local free-list is empty, it will acquire from the
global LRU list. The global LRU list can either satisfy it
by its global free-list or by shrinking the global inactive
list. Since we have acquired the global LRU list lock,
it will try to get at most LOCAL_FREE_TARGET elements
to the local free list.
5. When a new element is added to the bpf_htab, it will
first sit at the pending-list (of the local list) first.
The pending-list will be flushed to the global LRU list
when it needs to acquire free nodes from the global list
next time.
* Lock Consideration:
The LRU list has a lock (lru_lock). Each bucket of htab has a
lock (buck_lock). If both locks need to be acquired together,
the lock order is always lru_lock -> buck_lock and this only
happens in the bpf_lru_list.c logic.
In hashtab.c, both locks are not acquired together (i.e. one
lock is always released first before acquiring another lock).

Since commit
b45f64d16d45 ("mlxsw: spectrum_router: Use FIB notifications

During module removal, FIBs of the second type are removed following
NETDEV_UNREGISTER events sent. The other FIBs are still present in both
the driver's cache and the device's table.
Fix this by iterating over all the FIB tables in the device and flush

net: stmmac: Fix lack of link transition for fixed PHYs
Commit
52f95bbfcf72 ("stmmac: fix adjust link call in case of a switch

therefore invoking the adjust_link callback more than once, since this
is a fixed PHY and link events won't be generated.
This works fine the first time, because we start with phydev->irq =
PHY_POLL, so we call adjust_link, then we set phydev->irq =
PHY_IGNORE_INTERRUPT and we stop polling the PHY.
Now, if we called ndo_close(), which calls both phy_stop() and does an
explicit netif_carrier_off(), we end up with a link down. Upon calling
ndo_open() again, despite starting the PHY state machine, we have
PHY_IGNORE_INTERRUPT set, and we generate no link event at all, so the
link is permanently down.

bnx2: Wait for in-flight DMA to complete at probe stage
This is v2 post.
In commit
3e1be7a ("bnx2: Reset device during driver initialization"),
firmware requesting code was moved from open stage to probe stage.
The reason is in kdump kernel hardware iommu need device be reset in
driver probe stage, otherwise those in-flight DMA from 1st kernel
will continue going and look up into the newly created io-page tables.
However bnx2 chip resetting involves firmware requesting issue, that
need be done in open stage.
Michale Chan suggested we can just wait for the old in-flight DMA to
complete at probe stage, then though without device resetting, we
don't need to worry the old in-flight DMA could continue looking up
the newly created io-page tables.

Michael suggested to wait for the in-flight DMA to complete at probe
stage. So give up the old method of trying to reset chip at probe

====================
Netfilter updates for net-next
The following patchset contains a second batch of Netfilter updates for
your net-next tree. This includes a rework of the core hook
infrastructure that improves Netfilter performance by ~15% according to
synthetic benchmarks. Then, a large batch with ipset updates, including
a new hash:ipmac set type, via Jozsef Kadlecsik. This also includes a
couple of assorted updates.
Regarding the core hook infrastructure rework to improve performance,
using this simple drop-all packets ruleset from ingress:
nft add table netdev x
nft add chain netdev x y { type filter hook ingress device eth0 priority 0\; }
nft add rule netdev x y drop
And generating traffic through Jesper Brouer's
samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh script using -i
option. perf report shows nf_tables calls in its top 10:
17.30% kpktgend_0 [nf_tables] [k] nft_do_chain
15.75% kpktgend_0 [kernel.vmlinux] [k] __netif_receive_skb_core
10.39% kpktgend_0 [nf_tables_netdev] [k] nft_do_chain_netdev
I'm measuring here an improvement of ~15% in performance with this
patchset, so we got +2.5Mpps more. I have used my old laptop Intel(R)
Core(TM) i5-3320M CPU @ 2.60GHz 4-cores.
This rework contains more specifically, in strict order, these patches:
1) Remove compile-time debugging from core.
2) Remove obsolete comments that predate the rcu era. These days it is
well known that a Netfilter hook always runs under rcu_read_lock().
3) Remove threshold handling, this is only used by br_netfilter too.
We already have specific code to handle this from br_netfilter,
so remove this code from the core path.
4) Deprecate NF_STOP, as this is only used by br_netfilter.
5) Place nf_state_hook pointer into xt_action_param structure, so
this structure fits into one single cacheline according to pahole.
This also implicit affects nftables since it also relies on the
xt_action_param structure.
6) Move state->hook_entries into nf_queue entry. The hook_entries
pointer is only required by nf_queue(), so we can store this in the
queue entry instead.
7) use switch() statement to handle verdict cases.
8) Remove hook_entries field from nf_hook_state structure, this is only
required by nf_queue, so store it in nf_queue_entry structure.
9) Merge nf_iterate() into nf_hook_slow() that results in a much more
simple and readable function.
10) Handle NF_REPEAT away from the core, so far the only client is
nf_conntrack_in() and we can restart the packet processing using a
simple goto to jump back there when the TCP requires it.
This update required a second pass to fix fallout, fix from
Arnd Bergmann.
11) Set random seed from nft_hash when no seed is specified from
userspace.
12) Simplify nf_tables expression registration, in a much smarter way
to save lots of boiler plate code, by Liping Zhang.
13) Simplify layer 4 protocol conntrack tracker registration, from
Davide Caratti.
14) Missing CONFIG_NF_SOCKET_IPV4 dependency for udp4_lib_lookup, due
to recent generalization of the socket infrastructure, from Arnd
Bergmann.
15) Then, the ipset batch from Jozsef, he describes it as it follows:
* Cleanup: Remove extra whitespaces in ip_set.h
* Cleanup: Mark some of the helpers arguments as const in ip_set.h
* Cleanup: Group counter helper functions together in ip_set.h
* struct ip_set_skbinfo is introduced instead of open coded fields
in skbinfo get/init helper funcions.
* Use kmalloc() in comment extension helper instead of kzalloc()
because it is unnecessary to zero out the area just before
explicit initialization.
* Cleanup: Split extensions into separate files.
* Cleanup: Separate memsize calculation code into dedicated function.
* Cleanup: group ip_set_put_extensions() and ip_set_get_extensions()
together.
* Add element count to hash headers by Eric B Munson.
* Add element count to all set types header for uniform output
across all set types.
* Count non-static extension memory into memsize calculation for
userspace.
* Cleanup: Remove redundant mtype_expire() arguments, because
they can be get from other parameters.
* Cleanup: Simplify mtype_expire() for hash types by removing
one level of intendation.
* Make NLEN compile time constant for hash types.
* Make sure element data size is a multiple of u32 for the hash set
types.
* Optimize hash creation routine, exit as early as possible.
* Make struct htype per ipset family so nets array becomes fixed size
and thus simplifies the struct htype allocation.
* Collapse same condition body into a single one.
* Fix reported memory size for hash:* types, base hash bucket structure
was not taken into account.
* hash:ipmac type support added to ipset by Tomasz Chilinski.
* Use setup_timer() and mod_timer() instead of init_timer()
by Muhammad Falak R Wani, individually for the set type families.
16) Remove useless connlabel field in struct netns_ct, patch from
Florian Westphal.
17) xt_find_table_lock() doesn't return ERR_PTR() anymore, so simplify
{ip,ip6,arp}tables code that uses this.

====================
dsa: mv88e6xxx: Fixes for port refactoring
The patches which refactored setting up the switch MACs introduced a
couple of regressions. The RGMII delays for a port can be set using
other mechanism than just phy-mode. Don't overwrite the delays unless
explicitly asked to. This broke my Armada 370 RD. Also, the mv88e6351
family supports setting RGMII delays, but is missing the necessary
entries in the ops structures to allow this.
These fixes are to patches currently in net-next. No need for stable
etc.
