Lorenzo Colitti says:
====================
Make mark-based routing work better with multiple separate networks.
Mark-based routing (ip rule fwmark 17 lookup 100) combined with
either iptables marking (iptables -j MARK --set-mark 17) or
application-based marking (the SO_MARK setsockopt) are a good
way to deal with connecting simultaneously to multiple networks.
Each network can be given a routing table, and ip rules can
be configured to make different fwmarks select different
networks. Applications can select networks them by setting
appropriate socket marks, and iptables rules can be used to
handle non-aware applications, enforce policy, etc.
This patch series improves functionality when mark-based routing
is used in this way. Current behaviour has the following
limitations:
1. Kernel-originated replies that are not associated with a
socket always use a mark of zero. This means that, for
example, when the kernel sends a ping reply or a TCP reset,
it does not send it on the network from which it received the
original packet.
2. Path MTU discovery, which is triggered by incoming packets,
does not always work correctly, because the routing lookups it
uses to clone routes do not take the fwmark into account and
thus can happen in the wrong routing table.
3. Application-based marking works well for outbound connections,
but does not work well for incoming connections. Marking a
listening socket causes that socket to only accept
connections from a given network, and sockets that are
returned by accept() are not marked (and are thus not routed
correctly).
sysctl. This causes route lookups for kernel-generated replies
and PMTUD to use the fwmark of the packet that caused them.

net: support marking accepting TCP sockets
When using mark-based routing, sockets returned from accept()
may need to be marked differently depending on the incoming
connection request.
This is the case, for example, if different socket marks identify
different networks: a listening socket may want to accept
connections from all networks, but each connection should be
marked with the network that the request came in on, so that
subsequent packets are sent on the correct network.
This patch adds a sysctl to mark TCP sockets based on the fwmark
of the incoming SYN packet. If enabled, and an unmarked socket
receives a SYN, then the SYN packet's fwmark is written to the
connection's inet_request_sock, and later written back to the
accepted socket when the connection is established. If the
socket already has a nonzero mark, then the behaviour is the same
as it is today, i.e., the listening socket's fwmark is used.
Black-box tested using user-mode linux:
- IPv4/IPv6 SYN+ACK, FIN, etc. packets are routed based on the
mark of the incoming SYN packet.
- The socket returned by accept() is marked with the mark of the
incoming SYN packet.
- Tested with syncookies=1 and syncookies=2.

net: cdc_ncm/cdc_mbim: rework probing of NCM/MBIM functions
The NCM class match in the cdc_mbim driver is confusing and
cause unexpected behaviour. The USB core guarantees that a
USB interface is in altsetting 0 when probing starts. This
means that devices implementing a NCM 1.0 backwards
compatible MBIM function (a "NCM/MBIM function") always hit
the NCM entry in the cdc_mbim driver match table. Such
functions will never match any of the MBIM entries.
This causes unexpeced behaviour for cases where the NCM and
MBIM entries are differet, which is currently the case for
all except Ericsson devices.
Improve the probing of NCM/MBIM functions by looking up the
device again in the cdc_mbim match table after switching to
the MBIM identity.
The shared altsetting selection is updated to better
accommodate the new probing logic, returning the preferred
altsetting for the control interface instead of the data
interface. The control interface altsetting update is moved
to the cdc_mbim driver. It is never necessary to change the
control interface altsetting for NCM.

net: cdc_mbim: optionally use VLAN ID 4094 for IP session 0
The cdc_mbim driver maps 802.1q VLANs to MBIM IP and DSS
sessions. MBIM IP session 0 is handled as an exception and
is mapped to untagged frames.
This patch adds optional support for remapping MBIM IP
session 0 to 802.1q VLAN ID 4094 instead. The default
behaviour is not changed. The new behaviour is triggered
by adding a link for this previously unsupported VLAN.
The untagged mapping was chosen initially to support the
assumed most common use case: Most current MBIM devices only
support a single IP session (i.e. session 0 only), and using
untagged frames lets the users completely ignore the
additonal complexity of the multiplexing layer.
But when the multiplexing features of MBIM are used, then
this netdev gets a double meaning: It becomes the master
interface for all the VLAN subdevs the additional sessions
are mapped to, while still serving as the untagged IP
interface for session 0.
This can be problematic, especially when using Device Service
Streams (DSS), as have become apparent recently with the
availability of devices with real DSS support. Some use cases
need to e.g set a MTU which is higher than allowed for IP
Session 0. The dual role also leads to the situation where
the IP Session 0 interface cannot be taken down without
breaking unrelated IP or DSS sessions - a devastating side
effect which applications managing a simple IP session cannot
be expected to be aware of. A typical DHCP client will assume
that it should bring the interface down after releasing the
IP lease.
These problems can be avoided by tagging IP session 0 packets
too, making this session similar to all other multiplexed
sessions. This redefines the main netdev as an upper master
interface only.

net/sched/sch_api.c
The netlink conflict dealt with moving to netlink_capable() and
netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations
in non-init namespaces. These were simple transformations from
netlink_capable to netlink_ns_capable.
The Altera driver conflict was simply code removal overlapping some
void pointer cast cleanups in net-next.

efb842c45("sctp: optimize the sctp_sysctl_net_register"),
Since it doesn't kmemdup a sysctl_table for init_net, so the
init_net->sctp.sysctl_header->ctl_table_arg points to sctp_net_table
which is a static array pointer. So when doing sctp_sysctl_net_unregister,
it will free sctp_net_table, then we will get a NULL pointer dereference

eth: cpsw: Correctly attach to GPIO bitbang MDIO driver").
Fix potential null-pointer dereference at probe if the mdio-gpio device
has not been successfully probed yet.
The offending commit is plain wrong for a number of reasons. First of
all it accesses internal driver data of an unrelated device. Neither
does it check that the data is non-null (which it is in case the device
has not been probed yet).
Furthermore, the decision on whether to treat any driver data according
to the mdio-gpio driver's internals is made based on the node name. But
the name is not compared against "mdio" which is the normal name for the
node, but rather against "gpio" which the node does not have to be named
(and shouldn't be according to the binding documentation). [ If this
hack is to be kept out-of-tree it should at least be matching against
the compatible property. ]

====================
qlcnic: SR-IOV and FW-dump enhancements
This patch series contain following enhancements.
* SR-IOV enhancements:
- Allow SR-IOV VF's to probe in hypervisor. SR-IOV VF can be
uplinked to bridge/macvtap device with this change.
- Commands from VF are processed in process context
as it may sleep during PF-VF communication. Earlier
we use to process qlcnic_sriov_vf_set_multi function in
process context but now we process individual commands.
- As SR-IOV VF's can be uplinked to bridge/macvtap device
support mac-learning to allow communication through
embedded switch.
* FW-dump enhancement:
- Support to collect RDMEM section of firmware dump using
PEX DMA method for 82xx series adapter.
* Changes in v2:
- Removed unnecessary cast from void pointer to something
else and verified this issue in entire patch series as
per David Miller's suggestion.

I am working on overhauling RX checksum offload. Goals of this effort
are:
- Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY
- Preserve CHECKSUM_COMPLETE through encapsulation layers
- Don't do skb_checksum more than once per packet
- Unify GRO and non-GRO csum verification as much as possible
- Unify the checksum functions (checksum_init)
- Simply code
What is in this second patch set:
- Call common inet checksum validation functions in ICMP{4,6},
GRE{4,6}, and IGMP.
- In UDP, verify checksum before handing off to encap_rcv.
- Remove custom UDP checksum validation code in L2TP.
Please review carefully and test if possible, mucking with basic
checksum functions is always a little precarious :-)
