Up until now IPv6 unregistered multicast traffic would be flooded like
broadcast, even when MLD snooping was enabled on the bridge. This was
intentional as MLD packet traps were missing, preventing the bridge
driver from programming MDB entries to the device.
Previous patch added these traps, so we can now finally flood IPv6
unregistered multicast packets to specific ports via the multicast table
instead of flooding them to all ports via the broadcast table.

In commit 1c6c6d221e ("mlxsw: spectrum: Mirror certain packets to

However, certain packets are trapped in the device's router block, after
passing through the bridge block where they were potentially flooded.
Mark all packets coming from L3 traps, so that they won't be potentially

Since the skb is attached to the first control block of a fragmented
skb it is possible that the skb could be freed when reclaiming that
control block before all fragments of the skb have been consumed by
the hardware and unmapped.
This commit introduces first_cb and last_cb pointers to the skb
control block used by the driver to keep track of which transmit
control blocks within a transmit ring are the first and last ones
associated with the skb.
It then splits the bcmgenet_free_cb() function into transmit
(bcmgenet_free_tx_cb) and receive (bcmgenet_free_rx_cb) versions
that can handle the unmapping of dma mapped memory and cleaning up
the corresponding control block structure so that the skb is only
freed after the last associated transmit control block is reclaimed.

harmless. If we add more than 288 unicast addresses we will then read

While working on IPv6 route replace I realized we can have a
use-after-free in IPv4 in case the replaced route is offloaded and the
only one using its FIB info.
The problem is that fib_table_insert() drops the reference on the FIB
info of the replaced routes which is eventually freed via call_rcu().
Since the driver doesn't hold a reference on this FIB info it can cause
a use-after-free when it tries to clear the RTNH_F_OFFLOAD flag stored
in fi->fib_flags.
After running the following commands in a loop for enough time with a
KASAN enabled kernel I finally got the below trace.

The PF driver sets up a list of firmware commands from the VF driver that
needs to be forwarded to the PF for approval. This list is a 256-bit
bitmap. The code that sets up the bitmap falls apart on big-endian
architecture. __set_bit() does not work because it operates on long types
whereas the firmware interface is defined in u32 types, causing bits in
the wrong 32-bit word to be set.
Fix it by setting the proper bits on an array of u32.

When changing channels from combined to rx/tx or vice versa, the code
uses the wrong "sh" parameter to determine if we are reserving rings
for shared or non-shared mode. It should be using the ethtool requested
"sh" parameter instead of the current "sh" parameter.
Fix it by passing the "sh" parameter to bnxt_reserve_rings(). For
ethtool, we will pass in the requested "sh" parameter.

.ndo_get_stats64() may not be protected by RTNL and can race with

memory. Fix it by setting a new flag BNXT_STATE_READ_STATS and then
proceeding to read statistics memory only if the state is OPEN. The
close path that frees the memory clears the OPEN state and then waits
for the BNXT_STATE_READ_STATS to clear before proceeding to free the

Latest change in open-lldp code uses bytes 6-11 of perm_addr buffer
as the Ethernet source address for the host TLV packet.
Since our driver does not fill these bytes, they stay at zero and
the open-lldp code ends up sending the TLV packet with zero source
address and the switch drops this packet.
The fix is to initialize these bytes to 0xff. The open-lldp code
considers 0xff:ff:ff:ff:ff:ff as the invalid address and falls back to
use the host's mac address as the Ethernet source address.

ABI 4.x introduced the chained metadata format and made it the
only one possible. There are cases, however, where the old
format is preferred - mostly to make interoperation with VFs
using ABI 3.x easier for the datapath. In ABI 5.x we allowed
for more flexibility by selecting the metadata format based
on capabilities. The default was left to non-chained.
In case of fallback traffic, there is no capability telling the
driver there may be chained metadata. With a very stripped-
-down FW the default old metadata format would be selected
making the driver drop all fallback traffic.
This patch changes the default selection in the driver. It
should not hurt with old firmwares, because if they don't
advertise RSS they will not produce metadata anyway. New
firmwares advertising ABI 5.x, however, can depend on the
driver defaulting to chained format.

For historical reasons we enumerate the vNICs in order. This means
that if user configures breakout on a multiport card, the first
interface of the second port will have its MAC address changed.
What's worse, when moved from static information (HWInfo) to using
management FW (NSP), more features started depending on the port ids.
Right now in case of breakout first subport of the second port and
second subport of the first port will have their link info swapped.
Revise the ordering scheme so that first subport maintains its address.
Side effect of this change is that we will use base lane ids in
devlink (i.e. 40G ports will be 4 ids apart), e.g.:
pci/0000:04:00.0/0: type eth netdev p6p1
pci/0000:04:00.0/4: type eth netdev p6p2
Note that behaviour of phys_port_id is not changed since there is
a separate id number for the subport there.

Pull driver core updates from Greg KH:
"Here is the big driver core update for 4.13-rc1.
The large majority of this is a lot of cleanup of old fields in the
driver core structures and their remaining usages in random drivers.
All of those fixes have been reviewed by the various subsystem
maintainers. There's also some small firmware updates in here, a new
kobject uevent api interface that makes userspace interaction easier,
and a few other minor things.
All of these have been in linux-next for a long while with no reported
issues"

"The main changes in this cycle were:
- Add the SYSTEM_SCHEDULING bootup state to move various scheduler
debug checks earlier into the bootup. This turns silent and

- A round of restructuring and refactoring of the load-balancing and
topology code (Peter Zijlstra)
- Another round of consolidating ~20 of incremental scheduler code
history: this time in terms of wait-queue nomenclature. (I didn't
get much feedback on these renaming patches, and we can still
easily change any names I might have misplaced, so if anyone hates
a new name, please holler and I'll fix it.) (Ingo Molnar)

Mellanox, mlx5 fixes 2017-06-28
This series contains some fixes for the mlx5 core and netdev driver.
Please pull and let me know if there's any problem.
For -stable:
("net/mlx5e: Fix TX carrier errors report in get stats ndo") Kernels >= v4.7
("net/mlx5: Cancel delayed recovery work when unloading the driver") Kernels >= v4.10
* When applied to net-next this will introduce a contextual conflict, it
should be easy to resolve, (a spin_lock was changed to spin_lock_irqsave in net-next),
if you need any help with this please let me know.
("net/mlx5: Fix driver load error flow when firmware is stuck") Kernels >= v4.4*
* This patch fixes: 6c780a0267 ("net/mlx5: Wait for FW readiness before initializing command interface")
which was submitted two weeks ago and queued up for v4.4.
Sorry about the mess, but other than the above, this series doesn't introduce
any conflict with the current mlx5 IPSec offload series.

Previously the flower offloads never sends messages to the hardware,
and never registers a handler for receiving messages from hardware.
This patch enables the flower offloads to send control messages to
hardware when adding and removing flow rules. Additionally it
registers a control message rx handler for receiving stats updates
from hardware for each offloaded flow.
Additionally this patch adds 4 control message types; Add, modify and
delete flow, as well as flow stats. It also allows
nfp_flower_cmsg_get_data() to be used outside of cmsg.c.

Currently the number of TX queues that are allocated doesn't depend
on the number of TCs, the module always loads with max num of UP
per channel.
In order to prevent the allocation of unnecessary memory, the
module will load with minimum number of UPs per channel, and the
user will be able to control the number of TX queues per channel
by changing the number of TC to 8 using the tc command.
The variable num_up will hold the information about the current
number of UPs.
Due to the change, needed to remove the lines that set the value of
UP to be different than zero in the func "mlx4_en_select_queue",
since now the num of TX queues that are allocated is only one per channel
in default.
In order not to force the UP to be zero in case of only one TC, added
a condition before forcing it in the func "mlx4_en_fill_qp_context".
Tested:
After the module is loaded with minimum number of UP per channel, to
increase num of TCs to 8, use:
tc qdisc add dev ens8 root mqprio num_tc 8
In order to decrease the number of TCs to minimum number of UP per channel,
use:
tc qdisc del dev ens8 root

Until this patch, the number of UPs was hard coded for eight.
Replace this with a variable in struct "mlx4_en_port_profile".

The driver currently creates RX/TX queues during device probe, but
assigns IRQ's to them during device open. On reset, however,
IRQ's are assigned when resetting the queues. If there is a reset
while the device is closed and the device is later opened, the driver will
request IRQ's twice, causing the open to fail. This patch assigns
the IRQ's in the ibmvnic_init function after the queues are reset or
initialized, ensuring IRQ's are only requested once.

Some of the device interrupts should function as level interrupts. For
some hardware configurations this requires setting some control bits
so that if the interrupt status has not been cleared the interrupt
should be reissued.
Additionally, when using MSI or MSI-X interrupts, run the interrupt

In case a VLAN device is enslaved to a bridge we shouldn't create a
router interface (RIF) for it when it's configured with an IP address.
This is already handled by the driver for other types of netdevs, such
as physical ports and LAG devices.
If this IP address is then removed and the interface is subsequently
unlinked from the bridge, a NULL pointer dereference can happen, as the
original 802.1d FID was replaced with an rFID which was then deleted.
To reproduce:
$ ip link set dev enp3s0np9 up
$ ip link add name enp3s0np9.111 link enp3s0np9 type vlan id 111
$ ip link set dev enp3s0np9.111 up
$ ip link add name br0 type bridge
$ ip link set dev br0 up
$ ip link set enp3s0np9.111 master br0
$ ip address add dev enp3s0np9.111 192.168.0.1/24

This patchset adds support for Innova IPSec network interface card.
About Innova device:
--------------------
Innova is a network card with a ConnectX chip and an FPGA chip as a
bump-on-the-wire.
Internal
+----------+ Link +-----------------+
| +--------------+ FPGA | +------+
| ConnectX | | Shell +--+ QSFP |

+----------+ I2C | | SBU | | +------+
| +-------+ |
+--+----------+---+
| |
+--+--+ +---+---+
| DDR | | Flash |
+-----+ +-------+
The FPGA synthesized logic is loaded from dedicated flash storage and has
access to its own dedicated DDR RAM.
The ConnectX chip firmware programs the FPGA by accessing its configuration
space over either the slow internal I2C link or the high-speed internal link.
The FPGA logic is divided into a "Shell" and a "Sandbox Unit" (SBU).
mlx5_core driver (with CONFIG_MLX5_FPGA) handles all shell functionality,
while other components may handle the various SBU functionalities.
The driver opens high-speed reliable communication channels with the shell and
the SBU over the internal link.
These channels may be used for high-bandwidth configuration or for SBU-specific
out-of-band data paths.
About Innova IPSec device:
--------------------------
Innova IPSec is a network card that allows offloading IPSec cryptography operations
from the host CPU to the NIC. It is an Innova card with an IPSec SBU.
The hardware keeps the database of IPSec Security Associations (SADB) in the FPGA's
DDR memory.

|SADB | | |
+-----+ +-------+
Modes and ciphers:
Currently the following modes and ciphers are supported:
IPv4 and IPv6
ESP tunnel and transport modes
AES 128 and 256 bit encryption, with GCM authentication (RFC4106)
IV is generated using seqiv, in sync with Linux's geniv.
More modes and ciphers may be added later.
Notes:
In the future similar functionality will be included in a single-chip NIC.
About the driver:
-----------------
Patches 1-4 prepare some existing driver code for the new feature:
* Add support for reserved GIDs in the hardware GID table
* Allow multiple modules to enable hardware RoCE support independently
Patches 5-6 define structs and helper functions for QP work-queues.
Patches 7-11 add various FPGA-related features required for Innova.
IPSec.
Patch 12 adds abstraction layer for Mellanox IPSec-offload capable devices.
atches 13-16 add IPSec offload support to the mlx5 netdevice.
This driver services the new IPSec offload API introduced in commit
d77e38e612 ("xfrm: Add an IPsec hardware offloading API")
Configuration Path:
If Innova IPSec device is detected, the mlx5e netdevice gets the new
NETIF_F_HW_ESP feature and the xdo callbacks, indicating ESP offload
capabilities, and also the matching TX checksum and GSO features.
The driver configures offloaded Security Associations (SAs) by sending
an ADD_SA or DEL_SA message to the IPSec SBU, which updates the SADB in DDR.
These messages and their responses are sent over a high-speed channel.
Counters for ethtool are retrieved by the driver from the SBU.
Data path:
On receive path, the SBU decrypts ESP packets which match the offloaded SADB,
but keeps them encapsulated.
The SBU injects metadata (Mellanox owned ethertype) indicating that crypto-offload
has taken place, the SA with which it was done, and the authentication result.
The ConnectX chip performs RX checksum offload on the packet, and RSS using the
ESP SPI value. The driver detects the special ethertype, and attaches a struct
secpath to the RX SKB, including flags to indicate that crypto offload took place,
the authentication result, and which xfrm_state was used for decryption, in the
olen and ovec members. The RX SKB may have useful CHECKSUM_COMPLETE. A separate
patchset will add support for that in the xfrm stack.
On transmit path, the stack encapsulates the packet but does not encrypt it, and
indicates in the SKB's secpath that crypto offload is to be performed and the SA
to use to do so.
The driver avoids performing crypto-offload for ESP fragments, and packets with
IP options, as the SBU cannot currently do that. For eligible packets, the driver
prepends a special ethertype with metadata instructing the hardware to perform crypto offload.
The stack builds regular (non-GSO) SKBs so that they contain a placeholder for the ESP trailer.
The driver trims it off, because the SBU automatically appends the trailer for offloaded packets.
The ConnectX chip performs TX checksum offload on inner UDP or TCP packets,
and GSO for TCP packets (duplicating the prepended metadata).
The segmented packets then undergo encryption in the SBU before going on the wire.
Performance:
We measure single stream of TCP on Intel(R) Xeon(R) CPU E5-2643 v2 @3.50GHz
Using AES-NI with ESP GSO we get constant 4.1 Gbps.
Using crypto offload we get constant 18 Gbps.
Note that these numbers require CHECKSUM_COMPLETE support in XFRM, which we submit separately.

only because h/w timestamping for given skb is enabled with

outgoing packet is not timestamped at all if it's not PTP and h/w
