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
$ ip address del dev enp3s0np9.111 192.168.0.1/24
$ ip link set dev enp3s0np9.111 nomaster

When qdisc fail to init, qdisc_create would invoke the destroy callback
to cleanup. But there is no check if the callback exists really. So it
would cause the panic if there is no real destroy callback like the qdisc
codel, fq, and so on.
Take codel as an example following:
When a malicious user constructs one invalid netlink msg, it would cause
codel_init->codel_change->nla_parse_nested failed.
Then kernel would invoke the destroy callback directly but qdisc codel
doesn't define one. It causes one panic as a result.
Now add one the check for destroy to avoid the possible panic.

We don't hold any tx lock when trying to disable TX during reset, this
would lead a use after free since ndo_start_xmit() tries to access
the virtqueue which has already been freed. Fix this by using
netif_tx_disable() before freeing the vqs, this could make sure no tx
after vq freeing.

mlx5-updates-2017-06-27 (Innova IPsec offload support)
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 |
| +--------------+ +-------+ | | Port |
+----------+ 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.
Internal

+-----+ +-------+
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
d77e38e612a0 ("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.

The cpts can timestmap only ptp packets at this moment, so driver
cannot mark every packet as though it's going to be timestamped,
only because h/w timestamping for given skb is enabled with
SKBTX_HW_TSTAMP. It doesn't allow to use sw timestamping, as result
outgoing packet is not timestamped at all if it's not PTP and h/w
timestamping is enabled. So, fix it by setting SKBTX_IN_PROGRESS
only for PTP packets.

The current way to find if the phy is internal is to compare DT phy-mode
and emac_variant/internal_phy.
But it will negate a possible future SoC where an external PHY use the
same phy mode than the internal one.
By using phy-mode = "internal" we permit to have an external PHY with
the same mode than the internal one.

Wen reports significant memory leaks with DIF and O_DIRECT:
"With nvme devive + T10 enabled, On a system it has 256GB and started

When testcases with T10 enabled call into __blkdev_direct_IO_simple,
code doesn't free memory allocated by bio_integrity_alloc. The patch
fixes the issue. HTX has been run with +60 hours without failure."
Since __blkdev_direct_IO_simple() allocates the bio on the stack, it
doesn't go through the regular bio free. This means that any ancillary
data allocated with the bio through the stack is not freed. Hence, we
can leak the integrity data associated with the bio, if the device is
using DIF/DIX.
Fix this by providing a bio_uninit() and export it, so that we can use
it to free this data. Note that this is a minimal fix for this issue.
Any current user of bio's that are allocated outside of
bio_alloc_bioset() suffers from this issue, most notably some drivers.
We will fix those in a more comprehensive patch for 4.13. This also
means that the commit marked as being fixed by this isn't the real
culprit, it's just the most obvious one out there.

When user adds a virtual interface driver will set the
bss_type to the iface_type given by the user. When
supplicant is started on the same interface, a call to
change_virtual_intf will be triggered if if_type is not
NL80211_IFTYPE_STATION. Here driver should not update
it's bss_type, because bss_type is intended to indicate
the original iface_type and changing the same will defeat
the purpose of creating this interface.

The return value ret is unitialized and garbage is being returned
for the three different error conditions when setting up the PCIe
BARs. Fix this by initializing ret to -ENOMEM to indicate that
the BARs failed to be setup correctly.
