Pull networking updates from David Miller: 1) New offloading infrastructure and example 'rocker' driver for offloading of switching and routing to hardware. This work was done by a large group of dedicated individuals, not limited to: Scott Feldman, Jiri Pirko, Thomas Graf, John Fastabend, Jamal Hadi Salim, Andy Gospodarek, Florian Fainelli, Roopa Prabhu 2) Start making the networking operate on IOV iterators instead of modifying iov objects in-situ during transfers. Thanks to Al Viro and Herbert Xu. 3) A set of new netlink interfaces for the TIPC stack, from Richard Alpe. 4) Remove unnecessary looping during ipv6 routing lookups, from Martin KaFai Lau. 5) Add PAUSE frame generation support to gianfar driver, from Matei Pavaluca. 6) Allow for larger reordering levels in TCP, which are easily achievable in the real world right now, from Eric Dumazet. 7) Add a variable of napi_schedule that doesn't need to disable cpu interrupts, from Eric Dumazet. 8) Use a doubly linked list to optimize neigh_parms_release(), from Nicolas Dichtel. 9) Various enhancements to the kernel BPF verifier, and allow eBPF programs to actually be attached to sockets. From Alexei Starovoitov. 10) Support TSO/LSO in sunvnet driver, from David L Stevens. 11) Allow controlling ECN usage via routing metrics, from Florian Westphal. 12) Remote checksum offload, from Tom Herbert. 13) Add split-header receive, BQL, and xmit_more support to amd-xgbe driver, from Thomas Lendacky. 14) Add MPLS support to openvswitch, from Simon Horman. 15) Support wildcard tunnel endpoints in ipv6 tunnels, from Steffen Klassert. 16) Do gro flushes on a per-device basis using a timer, from Eric Dumazet. This tries to resolve the conflicting goals between the desired handling of bulk vs. RPC-like traffic. 17) Allow userspace to ask for the CPU upon what a packet was received/steered, via SO_INCOMING_CPU. From Eric Dumazet. 18) Limit GSO packets to half the current congestion window, from Eric Dumazet. 19) Add a generic helper so that all drivers set their RSS keys in a consistent way, from Eric Dumazet. 20) Add xmit_more support to enic driver, from Govindarajulu Varadarajan. 21) Add VLAN packet scheduler action, from Jiri Pirko. 22) Support configurable RSS hash functions via ethtool, from Eyal Perry. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1820 commits) Fix race condition between vxlan_sock_add and vxlan_sock_release net/macb: fix compilation warning for print_hex_dump() called with skb->mac_header net/mlx4: Add support for A0 steering net/mlx4: Refactor QUERY_PORT net/mlx4_core: Add explicit error message when rule doesn't meet configuration net/mlx4: Add A0 hybrid steering net/mlx4: Add mlx4_bitmap zone allocator net/mlx4: Add a check if there are too many reserved QPs net/mlx4: Change QP allocation scheme net/mlx4_core: Use tasklet for user-space CQ completion events net/mlx4_core: Mask out host side virtualization features for guests net/mlx4_en: Set csum level for encapsulated packets be2net: Export tunnel offloads only when a VxLAN tunnel is created gianfar: Fix dma check map error when DMA_API_DEBUG is enabled cxgb4/csiostor: Don't use MASTER_MUST for fw_hello call net: fec: only enable mdio interrupt before phy device link up net: fec: clear all interrupt events to support i.MX6SX net: fec: reset fep link status in suspend function net: sock: fix access via invalid file descriptor net: introduce helper macro for_each_cmsghdr ...

IPVLAN Driver HOWTO
|
||||
|
||||
Initial Release:
|
||||
Mahesh Bandewar <maheshb AT google.com>
|
||||
|
||||
1. Introduction:
|
||||
This is conceptually very similar to the macvlan driver with one major
|
||||
exception of using L3 for mux-ing /demux-ing among slaves. This property makes
|
||||
the master device share the L2 with it's slave devices. I have developed this
|
||||
driver in conjuntion with network namespaces and not sure if there is use case
|
||||
outside of it.
|
||||
|
||||
|
||||
2. Building and Installation:
|
||||
In order to build the driver, please select the config item CONFIG_IPVLAN.
|
||||
The driver can be built into the kernel (CONFIG_IPVLAN=y) or as a module
|
||||
(CONFIG_IPVLAN=m).
|
||||
|
||||
|
||||
3. Configuration:
|
||||
There are no module parameters for this driver and it can be configured
|
||||
using IProute2/ip utility.
|
||||
|
||||
ip link add link <master-dev> <slave-dev> type ipvlan mode { l2 | L3 }
|
||||
|
||||
e.g. ip link add link ipvl0 eth0 type ipvlan mode l2
|
||||
|
||||
|
||||
4. Operating modes:
|
||||
IPvlan has two modes of operation - L2 and L3. For a given master device,
|
||||
you can select one of these two modes and all slaves on that master will
|
||||
operate in the same (selected) mode. The RX mode is almost identical except
|
||||
that in L3 mode the slaves wont receive any multicast / broadcast traffic.
|
||||
L3 mode is more restrictive since routing is controlled from the other (mostly)
|
||||
default namespace.
|
||||
|
||||
4.1 L2 mode:
|
||||
In this mode TX processing happens on the stack instance attached to the
|
||||
slave device and packets are switched and queued to the master device to send
|
||||
out. In this mode the slaves will RX/TX multicast and broadcast (if applicable)
|
||||
as well.
|
||||
|
||||
4.2 L3 mode:
|
||||
In this mode TX processing upto L3 happens on the stack instance attached
|
||||
to the slave device and packets are switched to the stack instance of the
|
||||
master device for the L2 processing and routing from that instance will be
|
||||
used before packets are queued on the outbound device. In this mode the slaves
|
||||
will not receive nor can send multicast / broadcast traffic.
|
||||
|
||||
|
||||
5. What to choose (macvlan vs. ipvlan)?
|
||||
These two devices are very similar in many regards and the specific use
|
||||
case could very well define which device to choose. if one of the following
|
||||
situations defines your use case then you can choose to use ipvlan -
|
||||
(a) The Linux host that is connected to the external switch / router has
|
||||
policy configured that allows only one mac per port.
|
||||
(b) No of virtual devices created on a master exceed the mac capacity and
|
||||
puts the NIC in promiscous mode and degraded performance is a concern.
|
||||
(c) If the slave device is to be put into the hostile / untrusted network
|
||||
namespace where L2 on the slave could be changed / misused.
|
||||
|
||||
|
||||

Switch (and switch-ish) device drivers HOWTO
|
||||
===========================
|
||||
|
||||
Please note that the word "switch" is here used in very generic meaning.
|
||||
This include devices supporting L2/L3 but also various flow offloading chips,
|
||||
including switches embedded into SR-IOV NICs.
|
||||
|
||||
Lets describe a topology a bit. Imagine the following example:
|
||||
|
||||
+----------------------------+ +---------------+
|
||||
| SOME switch chip | | CPU |
|
||||
+----------------------------+ +---------------+
|
||||
port1 port2 port3 port4 MNGMNT | PCI-E |
|
||||
| | | | | +---------------+
|
||||
PHY PHY | | | | NIC0 NIC1
|
||||
| | | | | |
|
||||
| | +- PCI-E -+ | |
|
||||
| +------- MII -------+ |
|
||||
+------------- MII ------------+
|
||||
|
||||
In this example, there are two independent lines between the switch silicon
|
||||
and CPU. NIC0 and NIC1 drivers are not aware of a switch presence. They are
|
||||
separate from the switch driver. SOME switch chip is by managed by a driver
|
||||
via PCI-E device MNGMNT. Note that MNGMNT device, NIC0 and NIC1 may be
|
||||
connected to some other type of bus.
|
||||
|
||||
Now, for the previous example show the representation in kernel:
|
||||
|
||||
+----------------------------+ +---------------+
|
||||
| SOME switch chip | | CPU |
|
||||
+----------------------------+ +---------------+
|
||||
sw0p0 sw0p1 sw0p2 sw0p3 MNGMNT | PCI-E |
|
||||
| | | | | +---------------+
|
||||
PHY PHY | | | | eth0 eth1
|
||||
| | | | | |
|
||||
| | +- PCI-E -+ | |
|
||||
| +------- MII -------+ |
|
||||
+------------- MII ------------+
|
||||
|
||||
Lets call the example switch driver for SOME switch chip "SOMEswitch". This
|
||||
driver takes care of PCI-E device MNGMNT. There is a netdevice instance sw0pX
|
||||
created for each port of a switch. These netdevices are instances
|
||||
of "SOMEswitch" driver. sw0pX netdevices serve as a "representation"
|
||||
of the switch chip. eth0 and eth1 are instances of some other existing driver.
|
||||
|
||||
The only difference of the switch-port netdevice from the ordinary netdevice
|
||||
is that is implements couple more NDOs:
|
||||
|
||||
ndo_switch_parent_id_get - This returns the same ID for two port netdevices
|
||||
of the same physical switch chip. This is
|
||||
mandatory to be implemented by all switch drivers
|
||||
and serves the caller for recognition of a port
|
||||
netdevice.
|
||||
ndo_switch_parent_* - Functions that serve for a manipulation of the switch
|
||||
chip itself (it can be though of as a "parent" of the
|
||||
port, therefore the name). They are not port-specific.
|
||||
Caller might use arbitrary port netdevice of the same
|
||||
switch and it will make no difference.
