This command supports dumping all information about all links (including the broadcast link) or getting all information about a specific link (not the broadcast link).

2014-11-21tipc: add bearer disable/enable to new netlink apiRichard Alpe8-3/+320
A new netlink API for tipc that can disable or enable a tipc bearer. The new API is separated from the old API because of a bug in the user space client (tipc-config). The problem is that older versions of tipc-config has a very low receive limit and adding commands to the legacy genl_opts struct causes the ctrl_getfamily() response message to grow, subsequently breaking the tool. The new API utilizes netlink policies for input validation. Where the top-level netlink attributes are tipc-logical entities, like bearer. The top level entities then contain nested attributes. In this case a name, nested link properties and a domain.

2014-11-21net: sctp: keep owned chunk in destructor_arg instead of skb->cbDaniel Borkmann1-8/+4
It's just silly to hold the skb destructor argument around inside skb->cb[] as we currently do in SCTP. Nowadays, we're sort of cheating on data accounting in the sense that due to commit 4c3a5bdae293 ("sctp: Don't charge for data in sndbuf again when transmitting packet"), we orphan the skb already in the SCTP output path, i.e. giving back charged data memory, and use a different destructor only to make sure the sk doesn't vanish on skb destruction time. Thus, cb[] is still valid here as we operate within the SCTP layer. (It's generally actually a big candidate for future rework, imho.) However, storing the destructor in the cb[] can easily cause issues should an non sctp_packet_set_owner_w()'ed skb ever escape the SCTP layer, since cb[] may get overwritten by lower layers and thus can corrupt the chunk pointer. There are no such issues at present, but lets keep the chunk in destructor_arg, as this is the actual purpose for it.

Johan Hovold says: ==================== net: phy: add device-type abstraction This series adds device and device-type abstractions to the micrel driver, and enables support for RMII-reference clock selection for KSZ8081 and KSZ8091 devices. While adding support for more features for the Micrel PHYs mentioned above, it became apparent that the configuration space is much too large and that adding type-specific callbacks will simply not scale. Instead I added a driver_data field to struct phy_device, which can be used to store static device type data that can be parsed and acted on in generic driver callbacks. This allows a lot of duplicated code to be removed, and should make it much easier to add new features or deal with device-type quirks in the future. The series has been tested on a dual KSZ8081 setup. Further testing on other Micrel PHYs would be much appreciated. The recent commit a95a18afe4c8 ("phy/micrel: KSZ8031RNL RMII clock reconfiguration bug") currently prevents KSZ8031 PHYs from using the generic config-init. Bruno, who is the author of that patch, has agreed to test this series and some follow-up diagnostic patches to determine how best to incorporate these devices as well. I intend to send a follow-up patch that removes the custom 8031 config-init and documents this quirk, but the current series can be applied meanwhile. These patches are against net-next which contains some already merged prerequisite patches to the driver. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Note that some PHY revisions (of the same type) has this bit inverted. This should be either configurable through a new device-tree property, or preferably, determined based on PHY ID if possible. Also note that this removes support for setting 25 MHz mode from board files which was also added by the above mentioned commit 45f56cb82e45 ("net/phy: micrel: Add clock support for KSZ8021/KSZ8031").

2014-11-20bonding: change AD_LINK_SPEED_BITMASK to enum to suport more speedJianhua Xie1-32/+34
Port Key was determined as 16 bits according to the link speed, duplex and user key (which is yet not supported). In the old speed field, 5 bits are for speed [1|10|100|1000|10000]Mbps as below: -------------------------------------------------------------- Port key :| User key | Speed | Duplex| -------------------------------------------------------------- 16 6 1 0 This patch keeps the old layout, but changes AD_LINK_SPEED_BITMASK from bit type to an enum type. In this way, the speed field can expand speed type from 5 to 32. CC: Jay Vosburgh <j.vosburgh@gmail.com> CC: Veaceslav Falico <vfalico@gmail.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: David S.
