make it same as the netdev_switch_port_bridge_setlink/dellink api (ie traverse lowerdevs to get to the switch port). removes "WARN_ON(!ops->ndo_switch_parent_id_get)" because direct bridge ports can be stacked netdevices (like bonds and team of switch ports) which may not implement this ndo. v2 to v3: - remove changes to bond and team. Bring back the transparently following lowerdevs like i initially had for setlink/getlink (http://www.spinics.net/lists/netdev/msg313436.html) dave and scott feldman also seem to prefer it be that way and move to non-transparent way of doing things if we see a problem down the lane. v3 to v4: - fix ret initialization v4 to v5: - return err on first failure (scott feldman) v5 to v6: - change variable name (err) and initialize to -EOPNOTSUPP (scott feldman).

skb->priority can be set for two purposes: 1) With respect to IP TOS field, which is computed by a mask. Ususally used for priority qdisc's (pfifo, prio etc.), on TX side (we only have ingress qdisc on RX side). 2) Used as a classid or flowid, works in the same way with tc classid. What's more, this can even override the classid of tc filters. For case 1), it has been respected within its netns, I don't see any point of keeping it for another netns, especially when packets will be forwarded to Rx path (no matter from TX path or RX path). For case 2) we care, our applications run inside a netns, and we classify the packets by our own filters outside, If some application sets this priority, it could bypass our filters, therefore clear it when moving out of a netns, it makes no sense to bypass tc filters out of its netns.

Tadeusz Struk says: ==================== Add support for async socket operations After the iocb parameter has been removed from sendmsg() and recvmsg() ops the socket layer, and the network stack no longer support async operations. This patch set adds support for asynchronous operations on sockets back. Changes in v3: * As sugested by Al Viro instead of adding new functions aio_sendmsg and aio_recvmsg, added a ptr to iocb into the kernel-side msghdr structure. This way no change to aio.c is required. Changes in v2: * removed redundant total_size param from aio_sendmsg and aio_recvmsg functions ==================== Signed-off-by: -

The way the algif_skcipher works currently is that on sendmsg/sendpage it builds an sgl for the input data and then on read/recvmsg it sends the job for encryption putting the user to sleep till the data is processed. This way it can only handle one job at a given time. This patch changes it to be asynchronous by adding AIO support. Signed-off-by:

Murali Karicheri says: ==================== NetCP: Add support for version 1.5 NetCP 1.5 is used in newer K2 SoCs from Texas Instruments such as K2E, K2L etc. This patch series add support for Ethss driver for this version of NetCP. While at it, fix couple of bugs in the original driver. One of the earlier patch "net: netcp: select davinci_mdio driver by default" is folded onto this series. Please review and let me know your comments. ==================== Signed-off-by: -
WingMan Kwok authored
NetCP 1.5 available on newer K2 SoCs such as K2E and K2L introduced 3 variants of the ethss subsystem, 9 port, 5 port and 2 port. These have one host port towards the CPU and N external slave ports. To customize the driver for these new ethss sub systems, multiple compatibility strings are introduced. Currently some of parameters that are different on different variants such as number of ALE ports, stats modules and number of ports are defined through constants. These are now changed to variables in gbe_priv data that get set based on the compatibility string. This is required as there are no hardware identification registers available to distinguish among the variants of NetCP 1.5 ethss. However there is identification register available to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use of in the code to differentiate them.

Karicheri, Muralidharan authored
Ethss has multiple modules within the sub system - switch sub system - sgmii - mdio - switch module NetCP driver re-uses existing davinci mdio driver. It requires to have its own register region to map the reg space. So restructure the code to use separate reg region for the individual modules it manages. Use range property to define register space of NetCP and use reg property to define individual reg spaces. So MDIO will have its own reg space to map. This is a pre-requisite to enable MDIO driver for NetCP. Signed-off-by:

10G switch requires forward port number in the taginfo field, where as it should be in packet_info field for necp 1.4 Ethss. So fill this value correctly in the knav dma descriptor. Also rename dma_psflags field in struct netcp_tx_pipe to switch_to_port as it contain no flag, but the switch port number for forwarding the packet. Add a flag to hold the new flag, SWITCH_TO_PORT_IN_TAGINFO which will be set for 10G. This can also used in the future for other flags for the tx_pipe. Signed-off-by:

net: neighbour: Add mcast_resolicit to configure the number of multicast resolicitations in PROBE state. We send unicast neighbor (ARP or NDP) solicitations ucast_probes times in PROBE state. Zhu Yanjun reported that some implementation does not reply against them and the entry will become FAILED, which is undesirable. We had been dealt with such nodes by sending multicast probes mcast_ solicit times after unicast probes in PROBE state. In 2003, I made a change not to send them to improve compatibility with IPv6 NDP. Let's introduce per-protocol per-interface sysctl knob "mcast_ reprobe" to configure the number of multicast (re)solicitation for reconfirmation in PROBE state. The default is 0, since we have been doing so for 10+ years. Reported-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-03-20 This series contains updates to ixgb, e1000e, igb and igbvf. Eliezer and Todd provide patches to fix a potential issue found during code inspection. When bringing down an interface netif_carrier_off() should be one of the first things we do, since this will prevent the stack from queueing more packets to this interface. Yanir provides a fix for e1000e that was found in validating i219, where the call to e1000e_write_protect_nvm_ich8lan() is no longer supported in newer hardware. Access to these registers causes a system freeze in early steppings and is ignored in later steppings. ==================== Signed-off-by: -

Change bd76a116 made all DSA drivers depend on NET_DSA rather than selecting them. However, as the only way to select this option was to actually select a driver, it made DSA impossible to enable at all. This patch adds an explicit entry which the user will have to enable prior selecting a driver. Signed-off-by:

This reverts commit ca10b9e9. No longer needed after commit eb8895de ("tcp: tcp_make_synack() should use sock_wmalloc") When under SYNFLOOD, we build lot of SYNACK and hit false sharing because of multiple modifications done on sk_listener->sk_wmem_alloc Since tcp_make_synack() uses sock_wmalloc(), there is no need to call skb_set_owner_w() again, as this adds two atomic operations.

Daniel Borkmann says: ==================== This set adds native eBPF support also to act_bpf and thus covers tc with eBPF in the classifier *and* action part. A link to iproute2 preview has been provided in patch 2 and the code will be pushed out after Stephen has processed the classifier part and helper bits for tc. This set depends on ced585c8 ("act_bpf: allow non-default TC_ACT opcodes as BPF exec outcome"), so a net into net-next merge would be required first. Hope that's fine by you, Dave. ;) ==================== Signed-off-by:

This work extends the "classic" BPF programmable tc action by extending its scope also to native eBPF code! Together with commit e2e9b654 ("cls_bpf: add initial eBPF support for programmable classifiers") this adds the facility to implement fully flexible classifier and actions for tc that can be implemented in a C subset in user space, "safely" loaded into the kernel, and being run in native speed when JITed. Also, since eBPF maps can be shared between eBPF programs, it offers the possibility that cls_bpf and act_bpf can share data 1) between themselves and 2) between user space applications. That means that, f.e. customized runtime statistics can be collected in user space, but also more importantly classifier and action behaviour could be altered based on map input from the user space application. For the remaining details on the workflow and integration, see the cls_bpf commit e2e9b654. Preliminary iproute2 part can be found under [1].

In order to prepare eBPF support for tc action, we need to add sched_act_type, so that the eBPF verifier is aware of what helper function act_bpf may use, that it can load skb data and read out currently available skb fields. This is bascially analogous to 96be4325 ("ebpf: add sched_cls_type and map it to sk_filter's verifier ops"). BPF_PROG_TYPE_SCHED_CLS and BPF_PROG_TYPE_SCHED_ACT need to be separate since both will have a different set of functionality in future (classifier vs action), thus we won't run into ABI troubles when the point in time comes to diverge functionality from the classifier. The future plan for act_bpf would be that it will be able to write into skb->data and alter selected fields mirrored in struct __sk_buff. For an initial support, it's sufficient to map it to sk_filter_ops. Signed-off-by:

Conflicts: drivers/net/ethernet/emulex/benet/be_main.c net/core/sysctl_net_core.c net/ipv4/inet_diag.c The be_main.c conflict resolution was really tricky. The conflict hunks generated by GIT were very unhelpful, to say the least. It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: -
