| * net/ibm/emac: bump version numbers for correct work with ethtoolIvan Mikhaylov2015-09-281-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The size of the MAC register dump used to be the size specified by the reg property in the device tree. Userland has no good way of finding out that size, and it was not specified consistently for each MAC type, so ethtool would end up printing junk at the end of the register dump if the device tree didn't match the size it assumed. Using the new version numbers indicates unambiguously that the size of the MAC register dump is dependent only on the MAC type.

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.

* drivers:net: Convert dma_alloc_coherent(...__GFP_ZERO) to dma_zalloc_coherentJoe Perches2013-08-291-2/+2
| | | | | | | | | | | | | | | | | | | | | __GFP_ZERO is an uncommon flag and perhaps is better not used. static inline dma_zalloc_coherent exists so convert the uses of dma_alloc_coherent with __GFP_ZERO to the more common kernel style with zalloc. Remove memset from the static inline dma_zalloc_coherent and add just one use of __GFP_ZERO instead. Trivially reduces the size of the existing uses of dma_zalloc_coherent. Realign arguments as appropriate.

* emac: Fix EMAC soft reset on 460EX/GTPetri Gynther2013-05-111-8/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix EMAC soft reset on 460EX/GT to select the right PHY clock source before and after the soft reset. EMAC with PHY should use the clock from PHY during soft reset. EMAC without PHY should use the internal clock during soft reset. PPC460EX/GT Embedded Processor Advanced User's Manual section 28.10.1 Mode Register 0 (EMACx_MR0) states: Note: The PHY must provide a TX Clk in order to perform a soft reset of the EMAC. If none is present, select the internal clock (SDR0_ETH_CFG[EMACx_PHY_CLK] = 1). After a soft reset, select the external clock. Without the fix, 460EX/GT-based boards with RGMII PHYs attached to EMACs experience EMAC interrupt storm and system watchdog reset when issuing "ifconfig eth0 down" + "ifconfig eth0 up" a few times. The system enters endless loop of serving emac_irq() with EMACx_ISR register stuck at value 0x10000000 (Rx parity error). With the fix, the above issue is no longer observed.

In this commit we also update the various defconfigs that use EMAC to use the new Kconfig symbol, and explicitly add the NET_VENDOR_IBM guard. We do not explicitly select the Kconfig dependencies, as this would force EMAC on. Doing it in the defconfig allows more flexibility. Tested on a canyondlands board.
