A pointer to adapter struct is passed anyway to all of the FW-cmd routines in be_cmds.c. For routines which query data from FW, the adapter pointer is enough to return the queried fields. There is no need to separately pass pointers to individual members of the adapter structure. This patch fixes this for be_cmd_get_fw_ver() and be_cmd_get_fw_cfg() routines. Signed-off-by:

The netlink layer expects a -ve status value to be returned when a driver ndo method encounters an error. The driver was directly passing the error status returned by FW (a positive value) to the stack. This patch fixes this by returning -EIO status when a FW-cmd reports an error. Signed-off-by:

Currently we might arrive to bond_net_exit() with some bonds left (that were created while the module is unloading). We take care of that by destroying sysfs (the last possibility to add new bonds) and then destroying all the remaining bonds. However, we destroy the /proc/net/bonding directory before destroying those last bonds, and get a warning that we're trying to destroy a non-empty proc directory (containing /proc/net/bonding/bondX). Fix this by moving bond_destroy_proc_dir() after all the bonds are destroyed, so that we're sure that no bonds exist.

Anish Bhatt says: ==================== cxgb4i: Add ipv6 support The following patchset add ipv6 support for the cxgb4i(iscsi) driver. Patch 1 moves a define from the iw_cxgb4 to cxgb4 to prevent code duplication, as it is used by cxgb4i and iw_cxgb4 both. Patch 2 exports symbols needed by cxgb4i for ipv6 support from cxgb4. Patch 3 & 4 deal with actual ipv6 code in libcxgbi/cxgb4i. Submitting to net-next as changes were needed in cxgb4/iw_cxgb4, and submitting to scsi separately would break compilation, cc-ing scsi & rdma. v2 : Cleanup macro that prints ip addresses by using %pIS in patch 3 ==================== Signed-off-by: -

Current L2 hash helper calculates destination eth addr and source ether addr as L2 hash factors. This patch is adding packet type ID field into L2 hash factors. While one of BOND_XMIT_POLICY_LAYER2 or BOND_XMIT_POLICY_{LAYER|ENCAP}23 is applied, for the 2nd level hash, enhanced hash method can help to distribute different types of packets like IPv4/IPv6 packets to different slave devices.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-07-16 This series contains updates to i40e only. Neerav adds support to get the port MAC address from firmware and adds support to the ndo_get_phys_port_id() callback to provide port specific unique ids to the netdev layer. Jakub Kicinski provides 2 fixes, first fixes i40e to never generate a software time stamp if the hardware time stamp is provided. Second fixes a race condition on queueing skb for hardware time by using a simple bit lock to avoid race conditions and leaking skbs when multiple transmit rings try to claim time stamping. Paul does some general cleanup of the driver to remove unneeded spaces, comments that are no longer valid, and break that will never get touched. Jacob Keller adds a verbose warning message when the incorrect PF attempts to control timestamping for a port to which it was not assigned. The primary intent of this message is to help debugging the reason why the SIOCSHWSTAMP ioctl has failed and to help narrow the cause of the issue. ==================== Signed-off-by: -

In TLB mode if tlb_dynamic_lb is NOT set, slaves from the bond group are selected based on the hash distribution. This does not exclude dead links which are part of the bond. Also if there is a temporary link event which brings down the interface, packets hashed on that interface would be dropped too. This patch fixes these issues and distributes flows across the UP links only. Also the array construction of links which are capable of sending packets happen in the control path leaving only link-selection during the data-path. One possible side effect of this is - at a link event; all flows will be shuffled to get good distribution. But impact of this should be minimum with the assumption that a member or members of the bond group are not available is a very temporary situation. Signed-off-by:

sparse is throwing warnings when building sunrpc modules due to some endianness shenanigans in ipv6.h. Specifically: CHECK net/sunrpc/addr.c include/net/ipv6.h:573:17: warning: restricted __be64 degrades to integer include/net/ipv6.h:577:34: warning: restricted __be32 degrades to integer include/net/ipv6.h:573:17: warning: restricted __be64 degrades to integer include/net/ipv6.h:577:34: warning: restricted __be32 degrades to integer Sprinkle some endianness fixups to silence them. These should all get fixed up at compile time, so I don't think this will add any extra work to be done at runtime. Signed-off-by:

David Held says: ==================== udp: Fix multicast performance issues. Fix performance issues with listening to many different multicast sockets on different addresses with the same port. Instead of always using hash1, fall back to hash2 lookup when hash1 lookup is long. Patch 1 is a general cleanup and simplification which also makes the main implementation in Patch 2 simpler. Eric's recent change 63c6f81c avoided this being an issue in early demux. This makes it work for regular delivery as well. v1->v2 - updated hash collision detection v2->v3 - avoid flushing under lock unnecessarily at ARRAY_SIZE boundary ==================== Signed-off-by:

Many multicast sources can have the same port which can result in a very large list when hashing by port only. Hash by address and port instead if this is the case. This makes multicast more similar to unicast. On a 24-core machine receiving from 500 multicast sockets on the same port, before this patch 80% of system CPU was used up by spin locking and only ~25% of packets were successfully delivered. With this patch, all packets are delivered and kernel overhead is ~8% system CPU on spinlocks. Signed-off-by:

In B0 steering mode if promiscuous QP asks to be detached from MCG entry, and it is the only one in this entry then the entry will never be deleted. This is a wrong behavior since we don't want to keep those entries after the promiscuous QP becomes non-promiscuous. Therefore remove steering entry containing only promiscuous QP. Signed-off-by:

In current situation host is adding the promiscuous QP to all steering entries and the default entry as well. In this case when having PV and SR-IOV on the same setup bridge will receive all traffic that is targeted to the other VMs. This is bad. Solution: In SR-IOV mode host can add promiscuous QP to default entry only. The above problem and fix are relevant for B0 steering mode only. Signed-off-by:

When removing multicast address in B0 steering mode there is a bug in cases where there is a single QP registered for the address, and this QP is also promiscuous. In such cases the entry wouldn't be deleted from the SW structure representing all Ethernet MCG entries, but would be removed in HW. This way when driver goes to remove it from SW and HW structures the HW deletion fails. Moreover the same index could later be used for registering different address, which can be Infiniband.

Jon Paul Maloy authored
When we run broadcast packets over dual bearers/interfaces, the current transmission code is flipping bearers between each sent packet, with the purpose of leveraging the double bandwidth available. The receiving bclink is resequencing the packets if needed, so all messages are delivered upwards from the broadcast link in the correct order, even if they may arrive in concurrent interrupts. However, at the moment of delivery upwards to the socket, we release all spinlocks (bclink_lock, node_lock), so it is still possible that arriving messages bypass each other before they reach the socket queue. We fix this by applying the same technique we are using for unicast traffic. We use a link selector (i.e., the last bit of sending port number) to ensure that messages from the same sender socket always are sent over the same bearer. This guarantees sequential delivery between socket pairs, which is sufficient to satisfy the protocol spec, as well as all known user requirements. Signed-off-by:
