| Pull networking updates from David Miller: 1) The addition of nftables. No longer will we need protocol aware firewall filtering modules, it can all live in userspace. At the core of nftables is a, for lack of a better term, virtual machine that executes byte codes to inspect packet or metadata (arriving interface index, etc.) and make verdict decisions. Besides support for loading packet contents and comparing them, the interpreter supports lookups in various datastructures as fundamental operations. For example sets are supports, and therefore one could create a set of whitelist IP address entries which have ACCEPT verdicts attached to them, and use the appropriate byte codes to do such lookups. Since the interpreted code is composed in userspace, userspace can do things like optimize things before giving it to the kernel. Another major improvement is the capability of atomically updating portions of the ruleset. In the existing netfilter implementation, one has to update the entire rule set in order to make a change and this is very expensive. Userspace tools exist to create nftables rules using existing netfilter rule sets, but both kernel implementations will need to co-exist for quite some time as we transition from the old to the new stuff. Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have worked so hard on this. 2) Daniel Borkmann and Hannes Frederic Sowa made several improvements to our pseudo-random number generator, mostly used for things like UDP port randomization and netfitler, amongst other things. In particular the taus88 generater is updated to taus113, and test cases are added. 3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet and Yang Yingliang. 4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin Sujir. 5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet, Neal Cardwell, and Yuchung Cheng. 6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary control message data, much like other socket option attributes. From Francesco Fusco. 7) Allow applications to specify a cap on the rate computed automatically by the kernel for pacing flows, via a new SO_MAX_PACING_RATE socket option. From Eric Dumazet. 8) Make the initial autotuned send buffer sizing in TCP more closely reflect actual needs, from Eric Dumazet. 9) Currently early socket demux only happens for TCP sockets, but we can do it for connected UDP sockets too. Implementation from Shawn Bohrer. 10) Refactor inet socket demux with the goal of improving hash demux performance for listening sockets. With the main goals being able to use RCU lookups on even request sockets, and eliminating the listening lock contention. From Eric Dumazet. 11) The bonding layer has many demuxes in it's fast path, and an RCU conversion was started back in 3.11, several changes here extend the RCU usage to even more locations. From Ding Tianhong and Wang Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav Falico. 12) Allow stackability of segmentation offloads to, in particular, allow segmentation offloading over tunnels. From Eric Dumazet. 13) Significantly improve the handling of secret keys we input into the various hash functions in the inet hashtables, TCP fast open, as well as syncookies. From Hannes Frederic Sowa. The key fundamental operation is "net_get_random_once()" which uses static keys. Hannes even extended this to ipv4/ipv6 fragmentation handling and our generic flow dissector. 14) The generic driver layer takes care now to set the driver data to NULL on device removal, so it's no longer necessary for drivers to explicitly set it to NULL any more. Many drivers have been cleaned up in this way, from Jingoo Han. 15) Add a BPF based packet scheduler classifier, from Daniel Borkmann. 16) Improve CRC32 interfaces and generic SKB checksum iterators so that SCTP's checksumming can more cleanly be handled. Also from Daniel Borkmann. 17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces using the interface MTU value. This helps avoid PMTU attacks, particularly on DNS servers. From Hannes Frederic Sowa. 18) Use generic XPS for transmit queue steering rather than internal (re-)implementation in virtio-net.

| 2013-09-05 | ethernet/arc/arc_emac: Fix huge delays in large file copies | Vineet Gupta | |
| copying large files to a NFS mounted host was taking absurdly large time. Turns out that TX BD reclaim had a sublte bug. Loop starts off from @txbd_dirty cursor and stops when it hits a BD still in use by controller. However when it stops it needs to keep the cursor at that very BD to resume scanning in next iteration. However it was erroneously incrementing the cursor, causing the next scan(s) to fail too, unless the BD chain was completely drained out.

| 2013-08-13 | ethernet/arc/arc_emac - fix NAPI "work > weight" warning | Alexey Brodkin | |
| Initially I improperly set a boundary for maximum number of input packets to process on NAPI poll ("work") so it might be more than expected amount ("weight"). This was really harmless but seeing WARN_ON_ONCE on every device boot is not nice. So trivial fix ("<" instead of "<=") is here.

| 2013-06-26 | arc_emac: fix compile-time errors & warnings on PPC64 | Alexey Brodkin | |
| As reported by "kbuild test robot" there were some errors and warnings on attempt to build kernel with "make ARCH=powerpc allmodconfig". And this patch addresses both errors and warnings. Below is a list of introduced changes: 1. Fix compile-time errors (misspellings in "dma_unmap_single") on PPC. 2. Use DMA address instead of "skb->data" as a pointer to data buffer. This fixed warnings on pointer to int conversion on 64-bit systems. 3. Re-implemented initial allocation of Rx buffers in "arc_emac_open" in the same way they're re-allocated during operation (receiving packets). So once again DMA address could be used instead of "skb->data". 4. Explicitly use EMAC_BUFFER_SIZE for Rx buffers allocation.
