2017-06-20vxlan: allow multiple VXLANs with same VNI for IPv6 link-local addressesMatthias Schiffer1-23/+45
As link-local addresses are only valid for a single interface, we can allow to use the same VNI for multiple independent VXLANs, as long as the used interfaces are distinct. This way, VXLANs can always be used as a drop-in replacement for VLANs with greater ID space. This also extends VNI lookup to respect the ifindex when link-local IPv6 addresses are used, so using the same VNI on multiple interfaces can actually work.

2017-06-20vxlan: fix snooping for link-local IPv6 addressesMatthias Schiffer1-5/+15
If VXLAN is run over link-local IPv6 addresses, it is necessary to store the ifindex in the FDB entries. Otherwise, the used interface is undefined and unicast communication will most likely fail. Support for link-local IPv4 addresses should be possible as well, but as the semantics aren't as well defined as for IPv6, and there doesn't seem to be much interest in having the support, it's not implemented for now.

2017-06-20vxlan: check valid combinations of address scopesMatthias Schiffer1-0/+29
* Multicast addresses are never valid as local address * Link-local IPv6 unicast addresses may only be used as remote when the local address is link-local as well * Don't allow link-local IPv6 local/remote addresses without interface We also store in the flags field if link-local addresses are used for the follow-up patches that actually make VXLAN over link-local IPv6 work.

2017-06-20vxlan: improve validation of address family configurationMatthias Schiffer1-11/+28

2017-06-20vxlan: refactor verification and application of configurationMatthias Schiffer1-97/+111
The vxlan_dev_configure function was mixing validation and application of the vxlan configuration; this could easily lead to bugs with the changelink operation, as it was hard to see if the function wcould return an error after parts of the configuration had already been applied. This commit splits validation and application out of vxlan_dev_configure as separate functions to make it clearer where error returns are allowed and where the vxlan_dev or net_device may be configured. Log messages in these functions are removed, as it is generally unexpected to find error output for netlink requests in the kernel log. Userspace should be able to handle errors based on the error codes returned via netlink just fine. In addition, some validation and initialization is moved to vxlan_validate and vxlan_setup respectively to improve grouping of similar settings. Finally, this also fixes two actual bugs: * if set, conf->mtu would overwrite dev->mtu in each changelink operation, reverting other changes of dev->mtu * the "if (!conf->dst_port)" branch would never be run, as conf->dst_port was set in vxlan_setup before. This caused VXLAN-GPE to use the same default port as other VXLAN sockets instead of the intended IANA-assigned 4790.

This commit kills the IRL flags in favor of a new operation implementing the "Init all resources to the initial state" operation. This fixes the operation of 88E6390 family where 0x1000 means Read the selected resource 0, register 0 on port 16, instead of init all.

2017-06-20net-next: stmmac: dwmac-sun8i: force EPHY clock freq to 24MHzIcenowy Zheng1-0/+4
The EPHY control part of the EMAC syscon register has a bit called CLK_SEL. On the datasheet it says that if it's 0 the EPHY clock is 25MHz and if it's 1 the clock is 24MHz. However, according to the datasheets, no Allwinner SoC with EPHY has any extra xtal input pins for the EPHY, and the system xtal is 24MHz. That means the EPHY is not possible to get a 25MHz xtal input, and thus the frequency can only be 24MHz. It doesn't matter on H3 as the default value of H3 is 24MHz, however on V3s the default value is wrongly set to 25MHz, which prevented the EPHY from working properly. Force the EPHY clock frequency to 24MHz. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-06-20qed: SPQ async callback registrationMichal Kalderon7-55/+96
Whenever firmware indicates that there's an async indication it needs to handle, there's a switch-case where the right functionality is called based on function's personality and information. Before iWARP is added [as yet another client], switch over the SPQ into a callback-registered mechanism, allowing registration of the relevant event-processing logic based on the function's personality.

2017-06-19cxgb4: notify uP to route ctrlq compl to rdma rspqRaju Rangoju1-4/+6
During the module initialisation there is a possible race (basically race between uld and lld) where neither the uld nor lld notifies the uP about where to route the ctrl queue completions. LLD skips notifying uP as the rdma queues were not created by then (will leave it to ULD to notify the uP). As the ULD comes up, it also skips notifying the uP as the flag FULL_INIT_DONE is not set yet (ULD assumes that the interface is not up yet). Consequently, this race between uld and lld leaves uP unnotified about where to send the ctrl queue completions to, leading to iwarp RI_RES WR failure. Here is the race: CPU 0 CPU1 - allocates nic rx queus - t4_sge_alloc_ctrl_txq() (if rdma rsp queues exists, tell uP to route ctrl queue compl to rdma rspq) - acquires the mutex_lock - allocates rdma response queues - if FULL_INIT_DONE set, tell uP to route ctrl queue compl to rdma rspq - relinquishes mutex_lock - acquires the mutex_lock - enable_rx() - set FULL_INIT_DONE - relinquishes mutex_lock This patch fixes the above issue.

2017-06-19liquidio: replace info-pointer mode with buffer-pointer-only modePrasad Kanneganti11-109/+37
Each Octeon output ring can DMA packets to host memory in two modes: info- pointer mode and buffer-pointer-only mode. In info-pointer mode, Octeon takes two buffer pointers for each packet and places the length of the packet along with specified number of bytes from the beginning of the packet into one buffer and the rest of the packet in a separate buffer. In buffer-pointer-only mode, Octeon takes single buffer pointer and places the length of the packet at the beginning of the buffer followed by the packet data. This patch switches all Octeon output rings from info-pointer mode to buffer-pointer-only mode. This results in fewer DMA setups and cache line snoops.

In IPv6 routing code, struct rt6_info is created for each static route and RTF_CACHE route and inserted into fib6 tree. In both cases, dst ref count is not taken. As explained in the previous patch, this leads to the need of the dst garbage collector. This patch holds ref count of dst before inserting the route into fib6 tree and properly releases the dst when deleting it from the fib6 tree as a preparation in order to fully get rid of dst gc later. Also, correct fib6_age() logic to check dst->__refcnt to be 1 to indicate no user is referencing the dst. And remove dst_hold() in vrf_rt6_create() as ip6_dst_alloc() already puts dst->__refcnt to 1.

2017-06-16ibmvnic: driver initialization for kdump/kexecNathan Fontenot1-5/+19
When booting into the kdump/kexec kernel, pHyp and vios are not prepared for the initialization crq request and a failover transport event is generated. This is not handled correctly. At this point in initialization the driver is still in the 'probing' state and cannot handle a full reset of the driver as is normally done for a failover transport event. To correct this we catch driver resets while still in the 'probing' state and return EAGAIN. This results in the driver tearing down the main crq and calling ibmvnic_init() again.
