2017-10-20net: ipv6: Make inet6addr_validator a blocking notifierDavid Ahern1-4/+0
inet6addr_validator chain was added by commit 3ad7d2468f79f ("Ipvlan should return an error when an address is already in use") to allow address validation before changes are committed and to be able to fail the address change with an error back to the user. The address validation is not done for addresses received from router advertisements. Handling RAs in softirq context is the only reason for the notifier chain to be atomic versus blocking. Since the only current user, ipvlan, of the validator chain ignores softirq context, the notifier can be made blocking and simply not invoked for softirq path. The blocking option is needed by spectrum for example to validate resources for an adding an address to an interface.

2017-10-20s390/qeth: don't verify device when setting MAC addressJulian Wiedmann1-23/+0
There's no reason why l2_set_mac_address() should ever be called for a netdevice that's not owned by qeth. It's certainly not required for VLAN devices, which have their own netdev_ops. Also: 1) we don't do such validation for any of the other netdev_ops routines. 2) the code in question clearly has never been actually exercised; it's broken. After determining that the device is not owned by qeth, it would still use dev->ml_priv to write a qeth trace entry. Remove the check, and its helper that walked the global card list.

2017-10-20net: sh_eth: implement R-Car Gen[12] fallback compatibility stringsSimon Horman1-0/+2
Implement fallback compatibility strings for R-Car Gen 1 and 2. In the case of Renesas R-Car hardware we know that there are generations of SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme is being adopted for drivers for Renesas SoCs. Note that R-Car Gen2 and RZ/G1 have many compatible IP blocks. The approach that has been consistently taken for other IP blocks is to name common code, compatibility strings and so on after R-Car Gen2.

2017-10-20net: sh_eth: rename name structures as rcar_gen[12]_*Simon Horman1-15/+15
Rename structures describing R-Car SoCs as rcar_gen[12]_* rather than r8a77[79]x_*. This seems a little easier on the eyes. And will make things slightly cleaner in a follow-up patch that adds fallback-compatibility strings for these SoCs. Note that R-Car Gen2 and RZ/G1 have many compatible IP blocks. The approach that has been consistently taken for other IP blocks is to name common code, compatibility strings and so on after R-Car Gen2. Also rename sh_eth_set_rate_r8a777x as sh_eth_set_rate_rcar as it it is used by the R-Car generations supported by the driver. This patch should have no run-time effect and is compile-tested only.

2017-10-19ibmvnic: Enable TSO supportThomas Falcon2-8/+53
This patch enables TSO support. It includes additional buffers reserved exclusively for large packets. Throughput is greatly increased with TSO enabled, from about 1 Gb/s to 9 Gb/s on our test systems. Signed-off-by: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: David S.

2017-10-19ibmvnic: Enable scatter-gather supportThomas Falcon1-2/+21
This patch enables scatter gather support. Since there is no HW/FW scatter-gather support at this time, the driver needs to loop through each fragment and copy it to a contiguous, pre-mapped buffer entry.

2017-10-19tun: relax check on eth_get_headlen() return valueEric Dumazet1-1/+1
syzkaller hit the WARN() in tun_get_user(), providing skb with payload in fragments only, and nothing in skb->head GRO layer is fine with this, so relax the check.

2017-10-19thunderbolt: Right shifting to zero bug in tbnet_handle_packet()Dan Carpenter1-1/+1
There is a problem when we do: sequence = pkg->hdr.length_sn & TBIP_HDR_SN_MASK; sequence >>= TBIP_HDR_SN_SHIFT; TBIP_HDR_SN_SHIFT is 27, and right shifting a u8 27 bits is always going to result in zero. The fix is to declare these variables as u32.
