From Cong Wang. 2) RFC 5961 TCP blind data injection attack mitigation, from Eric Dumazet. 3) Networking user namespace support from Eric W. Biederman. 4) tuntap/virtio-net multiqueue support by Jason Wang. 5) Support for checksum offload of encapsulated packets (basically, tunneled traffic can still be checksummed by HW). From Joseph Gasparakis. 6) Allow BPF filter access to VLAN tags, from Eric Dumazet and Daniel Borkmann. 7) Bridge port parameters over netlink and BPDU blocking support from Stephen Hemminger. 8) Improve data access patterns during inet socket demux by rearranging socket layout, from Eric Dumazet. 9) TIPC protocol updates and cleanups from Ying Xue, Paul Gortmaker, and Jon Maloy. 10) Update TCP socket hash sizing to be more in line with current day realities. The existing heurstics were choosen a decade ago. From Eric Dumazet. 11) Fix races, queue bloat, and excessive wakeups in ATM and associated drivers, from Krzysztof Mazur and David Woodhouse. 12) Support DOVE (Distributed Overlay Virtual Ethernet) extensions in VXLAN driver, from David Stevens. 13) Add "oops_only" mode to netconsole, from Amerigo Wang. 14) Support set and query of VEB/VEPA bridge mode via PF_BRIDGE, also allow DCB netlink to work on namespaces other than the initial namespace. From John Fastabend. 15) Support PTP in the Tigon3 driver, from Matt Carlson. 16) tun/vhost zero copy fixes and improvements, plus turn it on by default, from Michael S. Tsirkin. 17) Support per-association statistics in SCTP, from Michele Baldessari. And many, many, driver updates, cleanups, and improvements. Too numerous to mention individually. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1722 commits) net/mlx4_en: Add support for destination MAC in steering rules net/mlx4_en: Use generic etherdevice.h functions. net: ethtool: Add destination MAC address to flow steering API bridge: add support of adding and deleting mdb entries bridge: notify mdb changes via netlink ndisc: Unexport ndisc_{build,send}_skb(). uapi: add missing netconf.h to export list pkt_sched: avoid requeues if possible solos-pci: fix double-free of TX skb in DMA mode bnx2: Fix accidental reversions. bna: Driver Version Updated to 3.1.2.1 bna: Firmware update bna: Add RX State bna: Rx Page Based Allocation bna: TX Intr Coalescing Fix bna: Tx and Rx Optimizations bna: Code Cleanup and Enhancements ath9k: check pdata variable before dereferencing it ath5k: RX timestamp is reported at end of frame ath9k_htc: RX timestamp is reported at end of frame ...

| * virtio_net: multiqueue supportJason Wang2012-12-091-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the multiqueue (VIRTIO_NET_F_MQ) support to virtio_net driver. VIRTIO_NET_F_MQ capable device could allow the driver to do packet transmission and reception through multiple queue pairs and does the packet steering to get better performance. By default, one one queue pair is used, user could change the number of queue pairs by ethtool in the next patch. When multiple queue pairs is used and the number of queue pairs is equal to the number of vcpus. Driver does the following optimizations to implement per-cpu virt queue pairs: - select the txq based on the smp processor id. - smp affinity hint to the cpu that owns the queue pairs. This could be used with the flow steering support of the device to guarantee the packets of a single flow is handled by the same cpu.

| | * | netfilter: ctnetlink: dump entries from the dying and unconfirmed listsPablo Neira Ayuso2012-12-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new operation to dump the content of the dying and unconfirmed lists. Under some situations, the global conntrack counter can be inconsistent with the number of entries that we can dump from the conntrack table. The way to resolve this is to allow dumping the content of the unconfirmed and dying lists, so far it was not possible to look at its content. This provides some extra instrumentation to resolve problematic situations in which anyone suspects memory leaks. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

Thus in practice both modes behave the same, but the default mode has some problems: - if packets are never consumed, fragments are never orphaned which cases a DOS for sender using zero copy transmit - overrun errors are hard to diagnose: fifo error is incremented only once so you can not distinguish between userspace that is stuck and a transient failure, tcpdump on the device does not show any traffic Userspace solves this simply by enabling IFF_ONE_QUEUE but there seems to be little point in not doing the right thing for everyone, by default.

The old channel type is of course still supported for HT. Also change the cfg80211 channel definition struct to support these by adding the relevant fields to it (and removing the _type field.) This also adds new helper functions: - cfg80211_chandef_create to create a channel def struct given the control channel and channel type, - cfg80211_chandef_identical to check if two channel definitions are identical - cfg80211_chandef_compatible to check if the given channel definitions are compatible, and return the wider of the two This isn't entirely complete, but that doesn't matter until we have a driver using it. In particular, it's missing - regulatory checks on the usable bandwidth (if that even makes sense) - regulatory TX power (database can't deal with it) - a proper channel compatibility calculation for the new channel types Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As mwifiex (and mac80211 in the software case) are the only drivers actually implementing remain-on-channel with channel type, userspace can't be relying on it. This is the case, as it's used only for P2P operations right now. Rather than adding a flag to tell userspace whether or not it can actually rely on it, simplify all the code by removing the ability to use different channel types. Leave only the validation of the attribute, so that if we extend it again later (with the needed capability flag), it can't break userspace sending invalid data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NL80211_CMD_TDLS_OPER command was previously used only for userspace request for the kernel code to perform TDLS operations. However, there are also cases where the driver may need to request operations from userspace, e.g., when using security on the AP path. Add a new cfg80211 function for generating a TDLS operation event for drivers to request a new link to be set up (NL80211_TDLS_SETUP) or an existing link to be torn down (NL80211_TDLS_TEARDOWN). Drivers can optionally use these events, e.g., based on noticing data traffic being sent to a peer station that is seen with good signal strength.

Allow drivers (and mac80211) to advertise support for per-interface TX power configuration.

The rest are mostly clean up and bug fixes." Also included is an NFC pull -- Samuel says: "With this one we have: - pn544 p2p support. - pn544 physical and HCI layers separation. We are getting the pn544 driver ready to support non i2c physical layers. - LLCP SNL (Service Name Lookup). This is the NFC p2p service discovery protocol. - LLCP datagram sockets (connection less) support. - IDR library usage for NFC devices indexes assignement. - NFC netlink extension for setting and getting LLCP link characteristics. - Various code style fixes and cleanups spread over the pn533, LLCP, HCI and pn544 code." There are a couple of mac80211 pulls as well -- Johannes says: "Please pull my mac80211-next tree to get the first round of new features for 3.8. We have: * finally, the mac80211 multi-channel work * scan improvements: - bg scan - scan flush - forced AP scan * cfg80211 tracing * a bit of new code to allow implementing SAE (secure authentication of equals) in managed mode Along with a few random improvements, features and fixes." and... "Please pull from mac80211-next (per below pull request) to get a few updates. Most important is probably the fix for the WDS regression that my previous pull request introduced. Other than that, I have some tracing code, two mesh updates and a change to allow drivers to calculate the AES CMAC subkeys without having to implement the GF_mulx operation themselves." On top of that are the usual updates to iwlwifi, ath9k, rt2x00, brcmfmac, mwifiex, and a few others here and there.

To do so, this patch adds a 'force' flag to the SCAN_TRIGGER command which tells cfg80211 to perform the scanning operation even if the vif is an AP and the beaconing has already started.

This is useful for collecting guaranteed fresh scan/survey result (e.g. on resume). For normal scan, flushing only happens on successful completion of a scan; i.e. it does not happen if the scan is aborted. For scheduled scan, previous scan results are flushed everytime when we get new scan results. This feature is enabled by default. Drivers can disable it by unsetting the NL80211_FEATURE_SCAN_FLUSH flag.

If BPDU is received from a leaf (edge) port, it should not be elected as root port. Why would you want to do this? If using STP on a bridge and the downstream bridges are not fully trusted; this prevents a hostile guest for rerouting traffic. Why not just use netfilter? Netfilter does not track of follow spanning tree decisions. It would be difficult and error prone to try and mirror STP resolution in netfilter module.

The port will be restarted if link is brought down, or removed and reattached.

By switching to a nested message, this can be used for other bridge parameters. This changes IFLA_PROTINFO attribute from one byte to a full nested set of attributes. This is safe for application interface because the old message used IFLA_PROTINFO and new one uses IFLA_PROTINFO | NLA_F_NESTED. The code adapts to old format requests, and therefore stays compatible with user mode RSTP daemon. Since the type field for nested and unnested attributes are different, and the old code in libnetlink doesn't do the mask, it is also safe to use with old versions of bridge monitor command. Note: although mode is only a boolean, treating it as a full byte since in the future someone will probably want to add more values (like macvlan has).
