The VNET_LE flag was introduced to fix accesses to virtio 1.0 headers that are always little-endian. It can also be used to handle the special case of a legacy little-endian device implemented by a big-endian host. Let's add a flag and ioctls for big-endian devices as well. If both flags are set, little-endian wins. Since this is isn't a common usecase, the feature is controlled by a kernel config option (not set by default). Both macvtap and tun are covered by this patch since they share the same API with userland. Signed-off-by: NGreg Kurz <gkurz@linux.vnet.ibm.com> Signed-off-by: NMichael S.

SRCU is not necessary to be compiled by default in all cases. For tinification efforts not compiling SRCU unless necessary is desirable. The current patch tries to make compiling SRCU optional by introducing a new Kconfig option CONFIG_SRCU which is selected when any of the components making use of SRCU are selected. If we do not select CONFIG_SRCU, srcu.o will not be compiled at all. text data bss dec hex filename 2007 0 0 2007 7d7 kernel/rcu/srcu.o Size of arch/powerpc/boot/zImage changes from text data bss dec hex filename 831552 64180 23944 919676 e087c arch/powerpc/boot/zImage : before 829504 64180 23952 917636 e0084 arch/powerpc/boot/zImage : after so the savings are about ~2000 bytes.

This driver is very similar to the macvlan driver except that it uses L3 on the frame to determine the logical interface while functioning as packet dispatcher. It inherits L2 of the master device hence the packets on wire will have the same L2 for all the packets originating from all virtual devices off of the same master device. This driver was developed keeping the namespace use-case in mind. Hence most of the examples given here take that as the base setup where main-device belongs to the default-ns and virtual devices are assigned to the additional namespaces. The device operates in two different modes and the difference in these two modes in primarily in the TX side. (a) L2 mode : In this mode, the device behaves as a L2 device. TX processing upto L2 happens on the stack of the virtual device associated with (namespace). Packets are switched after that into the main device (default-ns) and queued for xmit. RX processing is simple and all multicast, broadcast (if applicable), and unicast belonging to the address(es) are delivered to the virtual devices. (b) L3 mode : In this mode, the device behaves like a L3 device. TX processing upto L3 happens on the stack of the virtual device associated with (namespace). Packets are switched to the main-device (default-ns) for the L2 processing. Hence the routing table of the default-ns will be used in this mode. RX processins is somewhat similar to the L2 mode except that in this mode only Unicast packets are delivered to the virtual device while main-dev will handle all other packets. The devices can be added using the "ip" command from the iproute2 package - ip link add link <master> <virtual> type ipvlan mode [ l2 | l3 ] Signed-off-by: NMahesh Bandewar <maheshb@google.com> Cc: Eric Dumazet <edumazet@google.com> Cc: Maciej Żenczykowski <maze@google.com> Cc: Laurent Chavey <chavey@google.com> Cc: Tim Hockin <thockin@google.com> Cc: Brandon Philips <brandon.philips@coreos.com> Cc: Pavel Emelianov <xemul@parallels.com> Signed-off-by: NDavid S.

The netpoll packet receive code only becomes active if the netpoll rx_skb_hook is implemented, and there is not a single implementation of the netpoll rx_skb_hook in the kernel. All of the out of tree implementations I have found all call netpoll_poll which was removed from the kernel in 2011, so this change should not add any additional breakage. There are problems with the netpoll packet receive code. __netpoll_rx does not call dev_kfree_skb_irq or dev_kfree_skb_any in hard irq context. netpoll_neigh_reply leaks every skb it receives. Reception of packets does not work successfully on stacked devices (aka bonding, team, bridge, and vlans). Given that the netpoll packet receive code is buggy, there are no out of tree users that will be merged soon, and the code has not been used for in tree for a decade let's just remove it. Reverting this commit can server as a starting point for anyone who wants to resurrect netpoll packet reception support. Acked-by: NEric Dumazet <edumazet@google.com> Signed-off-by: N"Eric W.

Currently, there is no good possibility to debug netlink traffic that is being exchanged between kernel and user space. Therefore, this patch implements a netlink virtual device, so that netlink messages will be made visible to PF_PACKET sockets. Once there was an approach with a similar idea [1], but it got forgotten somehow. I think it makes most sense to accept the "overhead" of an extra netlink net device over implementing the same functionality from PF_PACKET sockets once again into netlink sockets. We have BPF filters that can already be easily applied which even have netlink extensions, we have RX_RING zero-copy between kernel- and user space that can be reused, and much more features. So instead of re-implementing all of this, we simply pass the skb to a given PF_PACKET socket for further analysis. Another nice benefit that comes from that is that no code needs to be changed in user space packet analyzers (maybe adding a dissector, but not more), thus out of the box, we can already capture pcap files of netlink traffic to debug/troubleshoot netlink problems. Also thanks goes to Thomas Graf, Flavio Leitner, Jesper Dangaard Brouer.

This patch introduces new network device called team. It supposes to be very fast, simple, userspace-driven alternative to existing bonding driver. Userspace library called libteam with couple of demo apps is available here: https://github.com/jpirko/libteam Note it's still in its dipers atm. team<->libteam use generic netlink for communication. That and rtnl suppose to be the only way to configure team device, no sysfs etc. Python binding of libteam was recently introduced. Daemon providing arpmon/miimon active-backup functionality will be introduced shortly. All what's necessary is already implemented in kernel team driver. v7->v8: - check ndo_ndo_vlan_rx_[add/kill]_vid functions before calling them. - use dev_kfree_skb_any() instead of dev_kfree_skb() v6->v7: - transmit and receive functions are not checked in hot paths. That also resolves memory leak on transmit when no port is present v5->v6: - changed couple of _rcu calls to non _rcu ones in non-readers v4->v5: - team_change_mtu() uses team->lock while travesing though port list - mac address changes are moved completely to jurisdiction of userspace daemon. This way the daemon can do FOM1, FOM2 and possibly other weird things with mac addresses. Only round-robin mode sets up all ports to bond's address then enslaved. - Extended Kconfig text v3->v4: - remove redundant synchronize_rcu from __team_change_mode() - revert "set and clear of mode_ops happens per pointer, not per byte" - extend comment of function __team_change_mode() v2->v3: - team_change_mtu() uses rcu version of list traversal to unwind - set and clear of mode_ops happens per pointer, not per byte - port hashlist changed to be embedded into team structure - error branch in team_port_enter() does cleanup now - fixed rtln->rtnl v1->v2: - modes are made as modules. Makes team more modular and extendable. - several commenters' nitpicks found on v1 were fixed - several other bugs were fixed. - note I ignored Eric's comment about roundrobin port selector as Eric's way may be easily implemented as another mode (mode "random") in future.
