This driver adds support for EtherCAT master module located on CCAT FPGA found on Beckhoff CX series industrial PCs. The driver exposes EtherCAT master as an ethernet interface. EtherCAT is a fieldbus protocol defined on top of ethernet and Beckhoff CX5020 PCs come with built-in EtherCAT master module located on a FPGA, which in turn is connected to a PCI bus.

Commit 1f0f467b670e "qlcnic: Add hwmon interface to export board temperature" introduced a randconfig build error in the case when the hwmon framework is built as a module and the qlcnic driver itself is built-in: drivers/built-in.o: In function `qlcnic_register_hwmon_dev': drivers/net/ethernet/qlogic/qlcnic/qlcnic_sysfs.c:1301: undefined reference to `hwmon_device_register_with_groups' drivers/built-in.o: In function `qlcnic_unregister_hwmon_dev': drivers/net/ethernet/qlogic/qlcnic/qlcnic_sysfs.c:1309: undefined reference to `hwmon_device_unregister'.

2014-05-07net: clean up snmp stats codeWANG Cong12-162/+103
commit 8f0ea0fe3a036a47767f9c80e (snmp: reduce percpu needs by 50%) reduced snmp array size to 1, so technically it doesn't have to be an array any more. What's more, after the following commit: commit 933393f58fef9963eac61db8093689544e29a600 Date: Thu Dec 22 11:58:51 2011 -0600 percpu: Remove irqsafe_cpu_xxx variants We simply say that regular this_cpu use must be safe regardless of preemption and interrupt state. That has no material change for x86 and s390 implementations of this_cpu operations. However, arches that do not provide their own implementation for this_cpu operations will now get code generated that disables interrupts instead of preemption. probably no arch wants to have SNMP_ARRAY_SZ == 2. At least after almost 3 years, no one complains. So, just convert the array to a single pointer and remove snmp_mib_init() and snmp_mib_free() as well.

2014-05-07Merge branch 'gso_forward'David S. Miller4-71/+59
Florian Westphal says: ==================== net: ip: push gso skb forwarding handling down the stack Turns out doing the segmentation in forwarding was not a bright idea, there are corner-cases where this has unintended side-effects. This patch pushes the segmentation downwards. After this, netif_skb_dev_features() function can be removed again, it was only added to fetch the features of the output device, we can just use skb->dev after the pushdown. Tested with following setup: host -> kvm_router -> kvm_host mtu 1500 mtu1280 - 'host' has route to kvm_host with locked mtu of 1500 - gso/gro enabled on all interfaces Did tests with all of following combinations: - netfilter conntrack off and on on kvm_router - virtio-net and e1000 driver on kvm_router - tcp and udp bulk xmit from host to kvm_host for tcp, I added TCPMSS mangling on kvm_host to make it lie about tcp mss. Also added a dummy '-t mangle -A POSTROUTING -p udp -f' rule to make sure no udp fragments are seen in the 'conntrack on' and 'virtio-net' case. Also checked (with ping -M do -s 1400)' that it still sends the wanted icmp error message when size exceeds 1280. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-05-07net: ip: push gso skb forwarding handling down the stackFlorian Westphal2-53/+48
Doing the segmentation in the forward path has one major drawback: When using virtio, we may process gso udp packets coming from host network stack. In that case, netfilter POSTROUTING will see one packet with udp header followed by multiple ip fragments. Delay the segmentation and do it after POSTROUTING invocation to avoid this.

2014-05-07net: ipv6: send pkttoobig immediately if orig frag size > mtuFlorian Westphal1-1/+5
If conntrack defragments incoming ipv6 frags it stores largest original frag size in ip6cb and sets ->local_df. We must thus first test the largest original frag size vs. mtu, and not vice versa. Without this patch PKTTOOBIG is still generated in ip6_fragment() later in the stack, but 1) IPSTATS_MIB_INTOOBIGERRORS won't increment 2) packet did (needlessly) traverse netfilter postrouting hook.

2014-05-07net: ipv4: ip_forward: fix inverted local_df testFlorian Westphal1-2/+2
local_df means 'ignore DF bit if set', so if its set we're allowed to perform ip fragmentation. This wasn't noticed earlier because the output path also drops such skbs (and emits needed icmp error) and because netfilter ip defrag did not set local_df until couple of days ago. Only difference is that DF-packets-larger-than MTU now discarded earlier (f.e. we avoid pointless netfilter postrouting trip). While at it, drop the repeated test ip_exceeds_mtu, checking it once is enough...

Ying Xue says: ==================== tipc: purge signal handler infrastructure When we delay some actions to be executed in asynchronous contexts, these usually add unnecessary code complexities, and make their behaviours unpredictable and indeterministic. Moreover, as the signal handler infrastructure is first stopped when tipc module is removed, this may cause some potential risks for us. For instance, although signal handler is already stopped, some tipc components still submit signal requests to signal handler infrastructure, which may lead to some resources not to be released or freed correctly. So the series aims to convert all actions being performed in tasklet context asynchronously with interface provided by signal handler infrastructure to be executed synchronously, thereby deleting the whole infrastructure of signal handler. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-05tipc: purge signal handler infrastructureYing Xue4-147/+2
In the previous commits of this series, we removed all asynchronous actions which were based on the tasklet handler - "tipc_k_signal()". So the moment has now come when we can completely remove the tasklet handler infrastructure. That is done with this commit.

Convert allocations of global variables associated with bclink from static way to dynamical way for the convenience of bclink instance initialisation. Meanwhile, this also helps TIPC support name space in the future easily.

As we are going to do more jobs when bc_lock is released, the two operations of holding/releasing the lock should be encapsulated with functions. In addition, we move bc_lock spin lock into tipc_bclink structure avoiding to define the global variable.

Since previously what all publications pertaining to the lost node were removed from name table was finished in tasklet context asynchronously, we need to TIPC_NAMES_GONE flag indicating whether the node cleanup work is finished or not. But now as the cleanup work has been finished when node lock is released, the flag becomes meaningless for us.
