2016-07-26ipvlan: Scrub skb before crossing the namespace boundryMahesh Bandewar1-14/+25
The earlier patch c3aaa06d5a63 (ipvlan: scrub skb before routing in L3 mode.) did this but only for TX path in L3 mode. This patch extends it for both the modes for TX/RX path. Signed-off-by: Mahesh Bandewar <maheshb@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-04-29ipvlan: Fix failure path in dev registration during link creationMahesh Bandewar1-11/+8
When newlink creation fails at device-registration, the port->count is decremented twice. Francesco Ruggeri (fruggeri@arista.com) found this issue in Macvlan and the same exists in IPvlan driver too. While fixing this issue I noticed another issue of missing unregister in case of failure, so adding it to the fix which is similar to the macvlan fix by Francesco in commit 308379607548 ("macvlan: fix failure during registration v3") Reported-by: Francesco Ruggeri <fruggeri@arista.com> Signed-off-by: Mahesh Bandewar <maheshb@google.com> CC: Eric Dumazet <edumazet@google.com> CC: Eric W.

2016-02-05ipvlan: inherit MTU from master deviceMahesh Bandewar1-0/+1
When we create IPvlan slave; we use ether_setup() and that sets up default MTU to 1500 while the master device may have lower / different MTU. Any subsequent changes to the masters' MTU are reflected into the slaves' MTU setting. However if those don't happen (most likely scenario), the slaves' MTU stays at 1500 which could be bad. This change adds code to inherit MTU from the master device instead of using the default value during the link initialization phase.

2015-12-16net: Rename NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASKTom Herbert1-1/+1
The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the set of features for offloading all checksums. This is a mask of the checksum offload related features bits. It is incorrect to set both NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for features of a device. This patch: - Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where NETIF_F_ALL_CSUM is being used as a mask). - Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to use NEITF_F_HW_CSUM in features list instead of NETIF_F_ALL_CSUM.

2015-11-17ipvlan: fix use after free of skbSabrina Dubroca1-1/+1
ipvlan_handle_frame is a rx_handler, and when it returns a value other than RX_HANDLER_CONSUMED (here, NET_RX_DROP aka RX_HANDLER_ANOTHER), __netif_receive_skb_core expects that the skb still exists and will process it further, but we just freed it.

Pass a **skb to ipvlan_rcv_frame so that if skb_share_check returns a new skb, we actually use it during further processing. It's safe to ignore the new skb in the ipvlan_xmit_* functions, because they call ipvlan_rcv_frame with local == true, so that dev_forward_skb is called and always takes ownership of the skb.

2015-10-22ipvlan: read direct ifindex instead of iflinkBrenden Blanco1-2/+2
In the ipv4 outbound path of an ipvlan device in l3 mode, the ifindex is being grabbed from dev_get_iflink. This works for the physical device case, since as the documentation of that function notes: "Physical interfaces have the same 'ifindex' and 'iflink' values.". However, if the master device is a veth, and the pairs are in separate net namespaces, the route lookup will fail with -ENODEV due to outer veth pair being in a separate namespace from the ipvlan master/routing namespace. ns0 | ns1 | ns2 veth0a--|--veth0b--|--ipvl0 In ipvlan_process_v4_outbound(), a packet sent from ipvl0 in the above configuration will pass fl.flowi4_oif == veth0a to ip_route_output_flow(), but *net == ns1. Notice also that ipv6 processing is not using iflink. Since there is a discrepancy in usage, fixup both v4 and v6 case to use local dev variable. Tested this with l3 ipvlan on top of veth, as well as with single physical interface in the top namespace.

2015-05-06ipvlan: Defer multicast / broadcast processing to a work-queueMahesh Bandewar3-52/+96
Processing multicast / broadcast in fast path is performance draining and having more links means more cloning and bringing performance down further. Broadcast; in particular, need to be given to all the virtual links. Earlier tricks of enabling broadcast bit for IPv4 only interfaces are not really working since it fails autoconf. Which means enabling broadcast for all the links if protocol specific hacks do not have to be added into the driver. This patch defers all (incoming as well as outgoing) multicast traffic to a work-queue leaving only the unicast traffic in the fast-path. Now if we need to apply any additional tricks to further reduce the impact of this (multicast / broadcast) type of traffic, it can be implemented while processing this work without affecting the fast-path.

When ipvlan interface with IP addresses attached is brought down and then deleted, the assigned addresses are deleted twice from the address hash list, first on the interface down and second on the link deletion. Similarly, when an address is added while the interface is down, it is added second time once the interface is brought up. When the interface is down, the addresses should be kept off the hash list for performance reasons. Ensure this is true, which also fixes the double add problem. To fix the double free, check whether the address is hashed before removing it.

2014-11-24ipvlan: Initial check-in of the IPVLAN driver.Mahesh Bandewar4-0/+1533
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: Mahesh 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: David S.
