2013-11-13Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-nextLinus Torvalds1-23/+18
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.

2013-10-01ll_temac: Reset dma descriptors indexes on ndo_openRicardo Ribalda1-0/+6
The dma descriptors indexes are only initialized on the probe function. If a packet is on the buffer when temac_stop is called, the dma descriptors indexes can be left on a incorrect state where no other package can be sent.

2013-03-09drivers:net: Remove unnecessary OOM messages after netdev_alloc_skbJoe Perches2-13/+6
Emitting netdev_alloc_skb and netdev_alloc_skb_ip_align OOM messages is unnecessary as there is already a dump_stack after allocation failures. Other trivial changes around these removals: Convert a few comparisons of pointer to 0 to !pointer. Change flow to remove unnecessary label. Remove now unused variable. Hoist assignment from if.

2013-02-04ethernet: Remove unnecessary alloc/OOM messages, alloc cleanupsJoe Perches1-4/+2
alloc failures already get standardized OOM messages and a dump_stack. Convert kzalloc's with multiplies to kcalloc. Convert kmalloc's with multiplies to kmalloc_array. Fix a few whitespace defects. Convert a constant 6 to ETH_ALEN. Use parentheses around sizeof. Convert vmalloc/memset to vzalloc. Remove now unused size variables.

Conflicts: Documentation/networking/ip-sysctl.txt drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c Both conflicts were simply overlapping context. A build fix for qlcnic is in here too, simply removing the added devinit annotations which no longer exist. Signed-off-by: David S. Miller <davem@davemloft.net>
2013-01-10net: ethernet: xilinx: Do not use NO_IRQ in axienetMichal Simek1-1/+1
This driver is used on Microblaze and will be used on Arm Zynq. Microblaze doesn't define NO_IRQ and no IRQ is 0. Arm still uses NO_IRQ as -1 and there is no option to connect IRQ to irq 0. That's why <= 0 is only one option how to find out undefined IRQ. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-01-10net: ethernet: xilinx: Do not use axienet on PPCMichal Simek1-1/+1
Axi ethernet can't be used on PPC because it is little endian IP and PPC is big endian. This system can't be designed. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-01-06ethtool: fix drvinfo strings set in driversJiri Pirko1-3/+2
Use strlcpy where possible to ensure the string is \0 terminated. Use always sizeof(string) instead of 32, ETHTOOL_BUSINFO_LEN and custom defines. Use snprintf instead of sprint. Remove unnecessary inits of ->fw_version Remove unnecessary inits of drvinfo struct. Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>
