We currently manage IRQs in pool_bm which is a bit field of MAX_MSIX bits. Thus, allocating more than MAX_MSIX interrupts can't be managed in pool_bm. Fixing this by capping number of requested MSIXs to MAX_MSIX. Signed-off-by:

While looking into fixing the local entries scalability issue I noticed that the structure is badly arranged because vlan_id would fall in a second cache line while keeping rcu which is used only when deleting in the first, so re-arrange the structure and push rcu to the end so we can get 16 bytes which can be used for other fields (by pushing rcu fully in the second 64 byte chunk). With this change all the core necessary information when doing fdb lookups will be available in a single cache line. pahole before (note vlan_id): struct net_bridge_fdb_entry { struct hlist_node hlist; /* 0 16 */ struct net_bridge_port * dst; /* 16 8 */ struct callback_head rcu; /* 24 16 */ long unsigned int updated; /* 40 8 */ long unsigned int used; /* 48 8 */ mac_addr addr; /* 56 6 */ unsigned char is_local:1; /* 62: 7 1 */ unsigned char is_static:1; /* 62: 6 1 */ unsigned char added_by_user:1; /* 62: 5 1 */ unsigned char added_by_external_learn:1; /* 62: 4 1 */ /* XXX 4 bits hole, try to pack */ /* XXX 1 byte hole, try to pack */ /* --- cacheline 1 boundary (64 bytes) --- */ __u16 vlan_id; /* 64 2 */ /* size: 72, cachelines: 2, members: 11 */ /* sum members: 65, holes: 1, sum holes: 1 */ /* bit holes: 1, sum bit holes: 4 bits */ /* padding: 6 */ /* last cacheline: 8 bytes */ } pahole after (note vlan_id): struct net_bridge_fdb_entry { struct hlist_node hlist; /* 0 16 */ struct net_bridge_port * dst; /* 16 8 */ long unsigned int updated; /* 24 8 */ long unsigned int used; /* 32 8 */ mac_addr addr; /* 40 6 */ __u16 vlan_id; /* 46 2 */ unsigned char is_local:1; /* 48: 7 1 */ unsigned char is_static:1; /* 48: 6 1 */ unsigned char added_by_user:1; /* 48: 5 1 */ unsigned char added_by_external_learn:1; /* 48: 4 1 */ /* XXX 4 bits hole, try to pack */ /* XXX 7 bytes hole, try to pack */ struct callback_head rcu; /* 56 16 */ /* --- cacheline 1 boundary (64 bytes) was 8 bytes ago --- */ /* size: 72, cachelines: 2, members: 11 */ /* sum members: 65, holes: 1, sum holes: 7 */ /* bit holes: 1, sum bit holes: 4 bits */ /* last cacheline: 8 bytes */ } Signed-off-by:Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by:

Ido Schimmel authored
The HW-SW contract requires mailboxes passed to the firmware to be 4KB aligned. Previously, these mailboxes were mapped using streaming DMA routines, which do not guarantee the bus addresses to be 4KB aligned. Under certain conditions this constraint was indeed violated and errors were observed. By using consistent DMA mapping routines together with a mailbox size of 4KB we are guaranteed not to violate the constraint. Signed-off-by:

Usually an skb does not have up to MAX_SKB_FRAGS frags. So no need to initialize the unuse part of sg. This patch initialize the sg based on the real number it will used: - during xmit, it could be inferred from nr_frags and can_push. - for small receive buffer, it will also be 2. Cc: Michael S.

Pravin B Shelar says: ==================== Geneve: Add support for tunnel metadata mode Following patches adds support for Geneve tunnel metadata mode. OVS can make use of Geneve net-device with tunnel metadata API from kernel. This also allows us to consolidate Geneve implementation from two kernel modules geneve_core and geneve to single geneve module. geneve_core module was targeted to share Geneve encap and decap code between Geneve netdevice and OVS Geneve tunnel implementation, Since OVS no longer needs these API, Geneve code can be consolidated into single geneve module. v3-v4: - Drop NETIF_F_NETNS_LOCAL feature. - Fix geneve device newlink check v2-v3: - make tunnel medata device and regular device mutually exclusive. - Fix Kconfig dependency for Geneve. - Fix dst-port netlink encoding. - drop changelink patch. v1-v2: - Replaced per hash table tunnel pointer (metadata enabled) with flag. - Added support for changelink. - Improve geneve device route lookup with more parameters. ==================== Signed-off-by: -

geneve_core module handles send and receive functionality. This way OVS could use the Geneve API. Now with use of tunnel meatadata mode OVS can directly use Geneve netdevice. So there is no need for separate module for Geneve. Following patch consolidates Geneve protocol processing in single module. Signed-off-by:

Commit 62ee783b ("smsc911x: Fix crash seen if neither ACPI nor OF is configured or used") introduces an error check for the return value from device_get_phy_mode() and bails out if there is an error. Unfortunately, there are configurations where no phy is configured. Those configurations now fail. To fix the problem, accept error returns from device_get_phy_mode(), and use the return value from device_property_read_u32() to determine if there is a suitable firmware interface to read the configuration.

For classifiers getting invoked via tc_classify(), we always need an extra function call into tc_classify_compat(), as both are being exported as symbols and tc_classify() itself doesn't do much except handling of reclassifications when tp->classify() returned with TC_ACT_RECLASSIFY. CBQ and ATM are the only qdiscs that directly call into tc_classify_compat(), all others use tc_classify(). When tc actions are being configured out in the kernel, tc_classify() effectively does nothing besides delegating. We could spare this layer and consolidate both functions. pktgen on single CPU constantly pushing skbs directly into the netif_receive_skb() path with a dummy classifier on ingress qdisc attached, improves slightly from 22.3Mpps to 23.1Mpps.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-08-26 This series contains updates to i40e and i40evf only. Anjali provides a fix for i40e where the part is not receiving multicast or VLAN tagged packets when in promiscuous mode. This can occur when a software bridge is created on top of the device. Fixed the legacy and MSI interrupt mode in the driver, which was non-existent before since we were assuming MSIX was the only mode that the driver ran in. Fixed the i40evf driver, where the wrong defines were getting used in the VF driver. Mitch fixes a sparse warning about comparing __le16 to u16 so use le16_to_cpu() to resolve the warning. Also fixed a dyslexic spelling of invalid. Shannon adds port.crc_errors to receive CRC error counter, since it is a receive counter. Catherine provides a fix to move the stopping of the service task and flow director to i40e_shutdown() instead of i40e_suspend(). Greg fixes the ethtool offline diagnostic with netqueues, which just need to be treated the same as virtual functions when someone wants to run the ethtool offline diagnostic test. Also fixed up code comments for the i40e ethtool diagnostic test function. Cleans up redundant and unneeded messages, since the kernel notifies all VXLAN capable registered drivers, so no need to log this. Neerav adds the ability to update statistics per VEB per traffic class and dump it via ethtool. Jingjing adds support for virtual channel offload to support receive polling mode in the VF driver. v2: dropped patch which added helper functions into a header, feedback from David Miller was to make the functions constant to reduce the driver footprint, so remove the patch while Anjali works on making the requested changes. ==================== Signed-off-by: -

Joe Stringer says: ==================== OVS conntrack support The goal of this series is to allow OVS to send packets through the Linux kernel connection tracker, and subsequently match on fields populated by conntrack. This functionality is enabled through a new CONFIG_OPENVSWITCH_CONNTRACK option. This version addresses the feedback from v5, primarily checking the behaviour is correct with different configurations such as disabling CONFIG_OPENVSWITCH_CONNTRACK or disabling individual conntrack features like connlabels. The branch below has been updated with the corresponding userspace pieces: https://github.com/joestringer/ovs dev/ct_20150818 ==================== Signed-off-by:

Add support for using conntrack helpers to assist protocol detection. The new OVS_CT_ATTR_HELPER attribute of the CT action specifies a helper to be used for this connection. If no helper is specified, then helpers will be automatically applied as per the sysctl configuration of net.netfilter.nf_conntrack_helper. The helper may be specified as part of the conntrack action, eg: ct(helper=ftp). Initial packets for related connections should be committed to allow later packets for the flow to be considered established. Example ovs-ofctl flows allowing FTP connections from ports 1->2: in_port=1,tcp,action=ct(helper=ftp,commit),2 in_port=2,tcp,ct_state=-trk,action=ct(recirc) in_port=2,tcp,ct_state=+trk-new+est,action=1 in_port=2,tcp,ct_state=+trk+rel,action=1 Signed-off-by:

Allow matching and setting the ct_label field. As with ct_mark, this is populated by executing the CT action. The label field may be modified by specifying a label and mask nested under the CT action. It is stored as metadata attached to the connection. Label modification occurs after lookup, and will only persist when the conntrack entry is committed by providing the COMMIT flag to the CT action. Labels are currently fixed to 128 bits in size.
