2013-09-06net: netlink: filter particular protocols from analyzersDaniel Borkmann
Fix finer-grained control and let only a whitelist of allowed netlink protocols pass, in our case related to networking. If later on, other subsystems decide they want to add their protocol as well to the list of allowed protocols they shall simply add it. While at it, we also need to tell what protocol is in use otherwise BPF_S_ANC_PROTOCOL can not pick it up (as it's not filled out).

sw_flow_key alignment was declared as " __aligned(__alignof__(long))". However, this breaks on the m68k architecture where long is 32 bit in size but 16 bit aligned by default. This aligns to the size of a long to ensure that we can always do comparsions in full long-sized chunks. It also adds an additional build check to catch any reduction in alignment.

2013-09-05net: mvneta: properly disable HW PHY polling and ensure adjust_link() worksThomas Petazzoni
This commit fixes a long-standing bug that has been reported by many users: on some Armada 370 platforms, only the network interface that has been used in U-Boot to tftp the kernel works properly in Linux. The other network interfaces can see a 'link up', but are unable to transmit data. The reports were generally made on the Armada 370-based Mirabox, but have also been given on the Armada 370-RD board. The network MAC in the Armada 370/XP (supported by the mvneta driver in Linux) has a functionality that allows it to continuously poll the PHY and directly update the MAC configuration accordingly (speed, duplex, etc.). The very first versions of the driver submitted for review were using this hardware mechanism, but due to this, the driver was not integrated with the kernel phylib. Following reviews, the driver was changed to use the phylib, and therefore a software based polling. In software based polling, Linux regularly talks to the PHY over the MDIO bus, and sees if the link status has changed. If it's the case then the adjust_link() callback of the driver is called to update the MAC configuration accordingly. However, it turns out that the adjust_link() callback was not configuring the hardware in a completely correct way: while it was setting the speed and duplex bits correctly, it wasn't telling the hardware to actually take into account those bits rather than what the hardware-based PHY polling mechanism has concluded. So, in fact the adjust_link() callback was basically a no-op. However, the network happened to be working because on the network interfaces used by U-Boot for tftp on Armada 370 platforms because the hardware PHY polling was enabled by the bootloader, and left enabled by Linux. However, the second network interface not used for tftp (or both network interfaces if the kernel is loaded from USB, NAND or SD card) didn't had the hardware PHY polling enabled. This patch fixes this situation by: (1) Making sure that the hardware PHY polling is disabled by clearing the MVNETA_PHY_POLLING_ENABLE bit in the MVNETA_UNIT_CONTROL register in the driver ->probe() function. (2) Making sure that the duplex and speed selections made by the adjust_link() callback are taken into account by clearing the MVNETA_GMAC_AN_SPEED_EN and MVNETA_GMAC_AN_DUPLEX_EN bits in the MVNETA_GMAC_AUTONEG_CONFIG register. This patch has been tested on Armada 370 Mirabox, and now both network interfaces are usable after boot.

2013-09-05ethernet/arc/arc_emac: Fix huge delays in large file copiesVineet Gupta
copying large files to a NFS mounted host was taking absurdly large time. Turns out that TX BD reclaim had a sublte bug. Loop starts off from @txbd_dirty cursor and stops when it hits a BD still in use by controller. However when it stops it needs to keep the cursor at that very BD to resume scanning in next iteration. However it was erroneously incrementing the cursor, causing the next scan(s) to fail too, unless the BD chain was completely drained out.

2013-09-05tuntap: orphan frags before trying to set tx timestampJason Wang
sock_tx_timestamp() will clear all zerocopy flags of skb which may lead the frags never to be orphaned. This will break guest to guest traffic when zerocopy is enabled. Fix this by orphaning the frags before trying to set tx time stamp. The issue were introduced by commit eda297729171fe16bf34fe5b0419dfb69060f623 (tun: Support software transmit time stamping).

2013-09-05qlcnic: use standard NAPI weightsMichal Schmidt
Since commit 82dc3c63 ("net: introduce NAPI_POLL_WEIGHT") netif_napi_add() produces an error message if a NAPI poll weight greater than 64 is requested. qlcnic requests the weight as large as 256 for some of its rings, and smaller values for other rings. For instance in qlcnic_82xx_napi_add() I think the intention was to give the tx+rx ring a bigger weight than to rx-only rings, but it's actually doing the opposite. So I'm assuming the weights do not really matter much. Just use the standard NAPI weights for all rings.

2013-09-05ipv6:introduce function to find route for redirectDuan Jiong
RFC 4861 says that the IP source address of the Redirect is the same as the current first-hop router for the specified ICMP Destination Address, so the gateway should be taken into consideration when we find the route for redirect. There was once a check in commit a6279458c534d01ccc39498aba61c93083ee0372 ("NDISC: Search over all possible rules on receipt of redirect.") and the check went away in commit b94f1c0904da9b8bf031667afc48080ba7c3e8c9 ("ipv6: Use icmpv6_notify() to propagate redirect, instead of rt6_redirect()"). The bug is only "exploitable" on layer-2 because the source address of the redirect is checked to be a valid link-local address but it makes spoofing a lot easier in the same L2 domain nonetheless.

2013-09-05vxlan: Notify drivers for listening UDP port changesJoseph Gasparakis
This patch adds two more ndo ops: ndo_add_rx_vxlan_port() and ndo_del_rx_vxlan_port(). Drivers can get notifications through the above functions about changes of the UDP listening port of VXLAN. Also, when physical ports come up, now they can call vxlan_get_rx_port() in order to obtain the port number(s) of the existing VXLAN interface in case they already up before them. This information about the listening UDP port would be used for VXLAN related offloads.

Currently if there is no listener for a certain group then IPv6 packets for that group are flooded on all ports, even though there might be no host and router interested in it on a port. With this commit they are only forwarded to ports with a multicast router. Just like commit bd4265fe36 ("bridge: Only flood unregistered groups to routers") did for IPv4, let's do the same for IPv6 with the same reasoning.
