Add flags to enable/disable supported chips in be2net.
With disable support are removed coresponding PCI IDs and
also codepaths with [BE2|BE3|BEx|lancer|skyhawk]_chip checks.
Disable chip will reduce module size by:
BE2 ~2kb
BE3 ~3kb
Lancer ~10kb
Skyhawk ~9kb
When enable skyhawk only it will reduce module size by ~20kb
New help style in Kconfig

IPv6 GRO over GRE tap is not working while GRO is not set
over the native interface.
gro_list_prepare function updates the same_flow variable
of existing sessions to 1 if their mac headers match the one
of the incoming packet.
same_flow is used to filter out non-matching sessions and keep
potential ones for aggregation.
The number of bytes to compare should be the number of bytes
in the mac headers. In gro_list_prepare this number is set to
be skb->dev->hard_header_len. For GRE interfaces this hard_header_len
should be as it is set in the initialization process (when GRE is
created), it should not be overridden. But currently it is being overridden
by the value that is actually supposed to represent the needed_headroom.
Therefore, the number of bytes compared in order to decide whether the
the mac headers are the same is greater than the length of the headers.
As it's documented in netdevice.h, hard_header_len is the maximum
hardware header length, and needed_headroom is the extra headroom
the hardware may need.
hard_header_len is basically all the bytes received by the physical
till layer 3 header of the packet received by the interface.
For example, if the interface is a GRE tap then the needed_headroom
should be the total length of the following headers:
IP header of the physical, GRE header, mac header of GRE.
It is often used to calculate the MTU of the created interface.
This patch removes the override of the hard_header_len, and
assigns the calculated value to needed_headroom.
This way, the comparison in gro_list_prepare is really of
the mac headers, and if the packets have the same mac headers
the same_flow will be set to 1.
Performance testing: 45% higher bandwidth.

The main motive of this patch is to lay down driver's
tc offload infrastructure in place.
With these changes tc can offload various supported flow
profiles (4 tuples, src-ip, dst-ip, l4 port) for the drop
action. Dropped flows statistic is a global counter for
all the offloaded flows for drop action and is populated
in ethtool statistics as common "gft_filter_drop".
Examples -
tc qdisc add dev p4p1 ingress
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
skip_sw ip_proto tcp dst_ip 192.168.40.200 action drop
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
skip_sw ip_proto udp src_ip 192.168.40.100 action drop
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \
skip_sw ip_proto tcp src_ip 192.168.40.100 dst_ip 192.168.40.200 \
src_port 453 dst_port 876 action drop

This patch adds support for dropping and redirecting
the flows based on destination IP in the packet.
This also moves the profile mode settings in their own
functions which can be used through tc flows in successive
patch.
For example -
ethtool -N p5p1 flow-type tcp4 dst-ip 192.168.40.100 action -1
ethtool -N p5p1 flow-type udp4 dst-ip 192.168.50.100 action 1

This patch adds support for tc mqprio offload,
using this different traffic classes on the adapter
can be utilized based on configured priority to tc map.
For example -
tc qdisc add dev eth0 root mqprio num_tc 4 map 0 1 2 3
This will cause SKBs with priority 0,1,2,3 to transmit
over tc 0,1,2,3 hardware queues respectively.

Allocating the main qeth_card struct with GFP_DMA blocks us from moving
it into netdev_priv(). But the only reason why we need DMA memory is the
ccw1 structs embedded into each ccw channel. So extract those into

The data channel currently doesn't need a setup operation, because we

It turns out I had misunderstood how the x86_match_cpu() function works.
It evaluates a logical OR of the matching conditions, not logical AND.
This caused the CPU feature checks for AEGIS to pass even if only SSE2
(but not AES-NI) was supported (or vice versa), leading to potential
crashes if something tried to use the registered algs.
This patch switches the checks to a simpler method that is used e.g. in
the Camellia x86 code.
The patch also removes the MODULE_DEVICE_TABLE declarations which
actually seem to cause the modules to be auto-loaded at boot, which is
not desired. The crypto API on-demand module loading is sufficient.

As it turns out, checking the TIF_NEED_RESCHED flag after each
iteration results in a significant performance regression (~10%)
when running fast algorithms (i.e., ones that use special instructions
and operate in the < 4 cycles per byte range) on in-order cores with
comparatively slow memory accesses such as the Cortex-A53.
Given the speed of these ciphers, and the fact that the page based
nature of the AEAD scatterwalk API guarantees that the core NEON
transform is never invoked with more than a single page's worth of
input, we can estimate the worst case duration of any resulting
scheduling blackout: on a 1 GHz Cortex-A53 running with 64k pages,
processing a page's worth of input at 4 cycles per byte results in
a delay of ~250 us, which is a reasonable upper bound.
So let's remove the yield checks from the fused AES-CCM and AES-GCM
routines entirely.
This reverts commit 7b67ae4d5ce8e2f912377f5fbccb95811a92097f and
partially reverts commit 7c50136a8aba8784f07fb66a950cc61a7f3d2ee3.

It was noticed that NIC always pass all multicast traffic to the host
regardless of IFF_ALLMULTI flag on the interface.
The rule in MC Filter Table in NIC, that is configured to accept any
multicast packets, is turning on if IFF_MULTICAST flag is set on the
interface. It leads to passing all multicast traffic to the host.
This fix changes the condition to turn on that rule by checking
IFF_ALLMULTI flag as it should.

AF_RXRPC has a keepalive message generator that generates a message for a
peer ~20s after the last transmission to that peer to keep firewall ports
open. The implementation is incorrect in the following ways:
(1) It mixes up ktime_t and time64_t types.
(2) It uses ktime_get_real(), the output of which may jump forward or
backward due to adjustments to the time of day.
(3) If the current time jumps forward too much or jumps backwards, the
generator function will crank the base of the time ring round one slot
at a time (ie. a 1s period) until it catches up, spewing out VERSION
packets as it goes.
Fix the problem by:
(1) Only using time64_t. There's no need for sub-second resolution.
(2) Use ktime_get_seconds() rather than ktime_get_real() so that time
isn't perceived to go backwards.
(3) Simplifying rxrpc_peer_keepalive_worker() by splitting it into two
parts:
(a) The "worker" function that manages the buckets and the timer.
(b) The "dispatch" function that takes the pending peers and
potentially transmits a keepalive packet before putting them back
in the ring into the slot appropriate to the revised last-Tx time.
(4) Taking everything that's pending out of the ring and splicing it into
a temporary collector list for processing.
In the case that there's been a significant jump forward, the ring
gets entirely emptied and then the time base can be warped forward
before the peers are processed.
The warping can't happen if the ring isn't empty because the slot a
peer is in is keepalive-time dependent, relative to the base time.
(5) Limit the number of iterations of the bucket array when scanning it.
(6) Set the timer to skip any empty slots as there's no point waking up if
there's nothing to do yet.
This can be triggered by an incoming call from a server after a reboot with
AF_RXRPC and AFS built into the kernel causing a peer record to be set up
before userspace is started. The system clock is then adjusted by
userspace, thereby potentially causing the keepalive generator to have a
meltdown - which leads to a message like:

Mellanox, mlx5e fixes 2018-08-07
I know it is late into 4.18 release, and this is why I am submitting
only two mlx5e ethernet fixes.
The first one from Or, is needed for -stable and it fixes hairpin
for "same device" check.
The second fix is a non risk fix from Huy which cleans up and improves
error return value reporting for dcbnl_ieee_setapp.
For -stable v4.16

llc_sap_put() decreases the refcnt before deleting sap
from the global list. Therefore, there is a chance
llc_sap_find() could find a sap with zero refcnt
in this global list.
Close this race condition by checking if refcnt is zero
or not in llc_sap_find(), if it is zero then it is being
removed so we can just treat it as gone.

The shift of 'cwnd' with '(now - hc->tx_lsndtime) / hc->tx_rto' value
can lead to undefined behavior [1].
In order to fix this use a gradual shift of the window with a 'while'
loop, similar to what tcp_cwnd_restart() is doing.
When comparing delta and RTO there is a minor difference between TCP
and DCCP, the last one also invokes dccp_cwnd_restart() and reduces
'cwnd' if delta equals RTO. That case is preserved in this change.

Commit 9faa89d4ed9d ("tipc: make function tipc_net_finalize() thread
safe") tries to make it thread safe to set node address, so it uses
node_list_lock lock to serialize the whole process of setting node
address in tipc_net_finalize(). But it causes the following interrupt
unsafe locking scenario:
CPU0 CPU1
---- ----
rht_deferred_worker()
rhashtable_rehash_table()
lock(&(&ht->lock)->rlock)
tipc_nl_compat_doit()
tipc_net_finalize()
local_irq_disable();
lock(&(&tn->node_list_lock)->rlock);
tipc_sk_reinit()
rhashtable_walk_enter()
lock(&(&ht->lock)->rlock);
<Interrupt>
tipc_disc_rcv()
tipc_node_check_dest()
tipc_node_create()
lock(&(&tn->node_list_lock)->rlock);
*** DEADLOCK ***
When rhashtable_rehash_table() holds ht->lock on CPU0, it doesn't
disable BH. So if an interrupt happens after the lock, it can create
an inverse lock ordering between ht->lock and tn->node_list_lock. As
a consequence, deadlock might happen.
The reason causing the inverse lock ordering scenario above is because
the initial purpose of node_list_lock is not designed to do the
serialization of node address setting.
As cmpxchg() can guarantee CAS (compare-and-swap) process is atomic,
we use it to replace node_list_lock to ensure setting node address can
be atomically finished. It turns out the potential deadlock can be
avoided as well.

The pattern is apparently wrong, we should only initialize
the dealyed work once and could repeatly schedule it. So we
have to move out the initializations to allocation side.
And to avoid confusion, we can split the shared dwork
into two, instead of re-using the same one.

Unlike fs.val.lport and fs.val.fport, cxgb4_process_flow_match()
sets fs.val.{l,f}ip to net-endian values without conversion - they come
straight from flow_dissector_key_ipv4_addrs ->dst and ->src resp. So
the assignment in mk_act_open_req() ought to be a straight copy.
As far as I know, T4 PCIe cards do exist, so it's not as if that
thing could only be found on little-endian systems...

TPACKET_V3 stores variable length frames in fixed length blocks.
Blocks must be able to store a block header, optional private space
and at least one minimum sized frame.
Frames, even for a zero snaplen packet, store metadata headers and
optional reserved space.
In the block size bounds check, ensure that the frame of the
chosen configuration fits. This includes sockaddr_ll and optional
tp_reserve.
Syzbot was able to construct a ring with insuffient room for the
sockaddr_ll in the header of a zero-length frame, triggering an
out-of-bounds write in dev_parse_header.
Convert the comparison to less than, as zero is a valid snap len.
This matches the test for minimum tp_frame_size immediately below.

device must be able to forward without further fragmentation while 576
bytes is the minimum size of IPv4 datagram every device has to be able
to receive, so in ip6_tnl_xmit(), 68(IPV4_MIN_MTU) should be the right
value for the ipv4 min mtu check in ip6_tnl_xmit.

All the callers of ip6_rt_copy_init()/rt6_set_from() hold refcnt
of the "from" fib6_info, so there is no need to hold fib6_metrics
refcnt again, because fib6_metrics refcnt is only released when
fib6_info is gone, that is, they have the same life time, so the
whole fib6_metrics refcnt can be removed actually.
This fixes a kmemleak warning reported by Sabrina.

For years I thought all parisc machines executed loads and stores in
order. However, Jeff Law recently indicated on gcc-patches that this is
not correct. There are various degrees of out-of-order execution all the
way back to the PA7xxx processor series (hit-under-miss). The PA8xxx
series has full out-of-order execution for both integer operations, and
loads and stores.
This is described in the following article:
http://web.archive.org/web/20040214092531/http://www.cpus.hp.com/technical_references/advperf.shtml
For this reason, we need to define mb() and to insert a memory barrier
before the store unlocking spinlocks. This ensures that all memory
accesses are complete prior to unlocking. The ldcw instruction performs
the same function on entry.

On some systems using edge triggered ACPI Event Interrupts, the initial
state at boot is not setup by the firmware, instead relying on the edge
irq event handler running at least once to setup the initial state.
2 known examples of this are:
1) The Surface 3 has its _LID state controlled by an ACPI operation region
triggered by a GPIO event:
OperationRegion (GPOR, GeneralPurposeIo, Zero, One)
Field (GPOR, ByteAcc, NoLock, Preserve)
{
Connection (
GpioIo (Shared, PullNone, 0x0000, 0x0000, IoRestrictionNone,
"\\_SB.GPO0", 0x00, ResourceConsumer, ,
)
{ // Pin list
0x004C
}
),
HELD, 1
}
Method (_E4C, 0, Serialized) // _Exx: Edge-Triggered GPE
{
If ((HELD == One))
{
^^LID.LIDB = One
}
Else
{
^^LID.LIDB = Zero
Notify (LID, 0x80) // Status Change
}
Notify (^^PCI0.SPI1.NTRG, One) // Device Check
}
Currently, the state of LIDB is wrong until the user actually closes or
open the cover. We need to trigger the GPIO event once to update the
internal ACPI state.
Coincidentally, this also enables the Surface 2 integrated HID sensor hub
which also requires an ACPI gpio operation region to start initialization.
2) Various Bay Trail based tablets come with an external USB mux and
TI T1210B USB phy to enable USB gadget mode. The mux is controlled by a
GPIO which is controlled by an edge triggered ACPI Event Interrupt which
monitors the micro-USB ID pin.
When the tablet is connected to a PC (or no cable is plugged in), the ID
pin is high and the tablet should be in gadget mode. But the GPIO
controlling the mux is initialized by the firmware so that the USB data
lines are muxed to the host controller.
This means that if the user wants to use gadget mode, the user needs to
first plug in a host-cable to force the ID pin low and then unplug it
and connect the tablet to a PC, to get the ACPI event handler to run and
switch the mux to device mode,
This commit fixes both by running the event-handler once on boot.
Note that the running of the event-handler is done from a late_initcall,
this is done because the handler AML code may rely on OperationRegions
registered by other builtin drivers. This avoids errors like these:
[ 0.133026] ACPI Error: No handler for Region [XSCG] ((____ptrval____)) [GenericSerialBus] (20180531/evregion-132)
[ 0.133036] ACPI Error: Region GenericSerialBus (ID=9) has no handler (20180531/exfldio-265)

Add support for XGMAC2 in stmmac
This series adds support for 10Gigabit IP in stmmac. The IP is called XGMAC2
and has many similarities with GMAC4. Due to this, its relatively easy to
incorporate this new IP into stmmac driver by adding a new block and
filling the necessary callbacks.
The functionality added by this series is still reduced but its only a
starting point which will later be expanded.
I splitted the patches into funcionality and to ease the review. Only the
patch 8/9 really enables the XGMAC2 block by adding a new compatible string.
Version 4 addresses review comments of Florian Fainelli and Rob Herring.
NOTE: Although the IP supports 10G, for now it was only possible to test it
at 1G speed due to 10G PHY HW shipping problems. Here follows iperf3
results at 1G:

Now that we have all the XGMAC related callbacks, lets start integrating
this IP block into main driver.
Also, we corrected the initialization flow to only start DMA after
setting descriptors length.

XGMAC2 uses the same engine of timestamping as GMAC4. Let's use the same
callbacks.
