John W. Linville says: ==================== This is a batch of updates intended for the 3.13 stream... The biggest item of interest in here is wcn36xx, the new mac80211 driver for Qualcomm WCN3660/WCN3680 hardware. Regarding the mac80211 bits, Johannes says: "We have an assortment of cleanups and new features, of which the biggest one is probably the channel-switch support in IBSS. Nothing else really stands out much." On top of that, the ath9k and rt2x00 get a lot of update action from Felix Fietkau and Gabor Juhos, respectively. There are a handful of updates to other drivers here and there as well. Please let me know if there are problems! ==================== Signed-off-by: -

xen-netback: IPv6 offload support ==================== This patch series adds support for checksum and large packet offloads into xen-netback. Testing has mainly been done using the Microsoft network hardware certification suite running in Server 2008R2 VMs with Citrix PV frontends. v2: - Fixed Wei's email address in Cc lines v3: - Responded to Wei's comments: - netif.h now updated with comments and a definition of XEN_NETIF_GSO_TYPE_NONE. - limited number of pullups - Responded to Annie's comments: - New GSO_BIT macro v4: - Responded to more of Wei's comments - Remove parsing of IPv6 fragment header and added warning v5: - Added comment concerning the value chosen for PKT_PROT_LEN - Dropped deprecation of feature-no-csum-offload ==================== Signed-off-by: -

This patch adds code to handle SKB_GSO_TCPV6 skbs and construct appropriate extra or prefix segments to pass the large packet to the frontend. New xenstore flags, feature-gso-tcpv6 and feature-gso-tcpv6-prefix, are sampled to determine if the frontend is capable of handling such packets. Signed-off-by:

This patch adds a xenstore feature flag, festure-gso-tcpv6, to advertise that netback can handle IPv6 TCP GSO packets. It creates SKB_GSO_TCPV6 skbs if the frontend passes an extra segment with the new type XEN_NETIF_GSO_TYPE_TCPV6 added to netif.h. Signed-off-by:

For performance of VM to VM traffic on a single host it is better to avoid calculation of TCP/UDP checksum in the sending frontend. To allow this this patch adds the code necessary to set up partial checksum for IPv6 packets and xenstore flag feature-ipv6-csum-offload to advertise that fact to frontends. Signed-off-by:

Pablo Neira Ayuso says: ==================== netfilter updates: nf_tables pull request The following patchset contains the current original nf_tables tree condensed in 17 patches. I have organized them by chronogical order since the original nf_tables code was released in 2009 and by dependencies between the different patches. The patches are: 1) Adapt all existing hooks in the tree to pass hook ops to the hook callback function, required by nf_tables, from Patrick McHardy. 2) Move alloc_null_binding to nf_nat_core, as it is now also needed by nf_tables and ip_tables, original patch from Patrick McHardy but required major changes to adapt it to the current tree that I made. 3) Add nf_tables core, including the netlink API, the packet filtering engine, expressions and built-in tables, from Patrick McHardy. This patch includes accumulated fixes since 2009 and minor enhancements. The patch description contains a list of references to the original patches for the record. For those that are not familiar to the original work, see [1], [2] and [3]. 4) Add netlink set API, this replaces the original set infrastructure to introduce a netlink API to add/delete sets and to add/delete set elements. This includes two set types: the hash and the rb-tree sets (used for interval based matching). The main difference with ipset is that this infrastructure is data type agnostic. Patch from Patrick McHardy. 5) Allow expression operation overload, this API change allows us to provide define expression subtypes depending on the configuration that is received from user-space via Netlink. It is used by follow up patches to provide optimized versions of the payload and cmp expressions and the x_tables compatibility layer, from Patrick McHardy. 6) Add optimized data comparison operation, it requires the previous patch, from Patrick McHardy. 7) Add optimized payload implementation, it requires patch 5, from Patrick McHardy. 8) Convert built-in tables to chain types. Each chain type have special semantics (filter, route and nat) that are used by userspace to configure the chain behaviour. The main chain regarding iptables is that tables become containers of chain, with no specific semantics. However, you may still configure your tables and chains to retain iptables like semantics, patch from me. 9) Add compatibility layer for x_tables. This patch adds support to use all existing x_tables extensions from nf_tables, this is used to provide a userspace utility that accepts iptables syntax but used internally the nf_tables kernel core. This patch includes missing features in the nf_tables core such as the per-chain stats, default chain policy and number of chain references, which are required by the iptables compatibility userspace tool. Patch from me. 10) Fix transport protocol matching, this fix is a side effect of the x_tables compatibility layer, which now provides a pointer to the transport header, from me. 11) Add support for dormant tables, this feature allows you to disable all chains and rules that are contained in one table, from me. 12) Add IPv6 NAT support. At the time nf_tables was made, there was no NAT IPv6 support yet, from Tomasz Bursztyka. 13) Complete net namespace support. This patch register the protocol family per net namespace, so tables (thus, other objects contained in tables such as sets, chains and rules) are only visible from the corresponding net namespace, from me. 14) Add the insert operation to the nf_tables netlink API, this requires adding a new position attribute that allow us to locate where in the ruleset a rule needs to be inserted, from Eric Leblond. 15) Add rule batching support, including atomic rule-set updates by using rule-set generations. This patch includes a change to nfnetlink to include two new control messages to indicate the beginning and the end of a batch. The end message is interpreted as the commit message, if it's missing, then the rule-set updates contained in the batch are aborted, from me. 16) Add trace support to the nf_tables packet filtering core, from me. 17) Add ARP filtering support, original patch from Patrick McHardy, but adapted to fit into the chain type infrastructure. This was recovered to be used by nft userspace tool and our compatibility arptables userspace tool. There is still work to do to fully replace x_tables [4] [5] but that can be done incrementally by extending our netlink API. Moreover, looking at netfilter-devel and the amount of contributions to nf_tables we've been getting, I think it would be good to have it mainstream to avoid accumulating large patchsets skip continuous rebases. I tried to provide a reasonable patchset, we have more than 100 accumulated patches in the original nf_tables tree, so I collapsed many of the small fixes to the main patch we had since 2009 and provide a small batch for review to netdev, while trying to retain part of the history. For those who didn't give a try to nf_tables yet, there's a quick howto available from Eric Leblond that describes how to get things working [6]. Comments/reviews welcome. Thanks!

Mellanox ConnectX architecture is: mlx4_core is the lower level PCI driver which register on the PCI id, and protocol specific drivers are depended on it: mlx4_en - for Ethernet and mlx4_ib for Infiniband. NIC could have multiple ports which can change their type dynamically. We use the request_module() call to load the relevant protocol driver when needed: on loading time or at port type change event.
