No longer will we need protocol aware\n firewall filtering modules, it can all live in userspace.\n\n At the core of nftables is a, for lack of a better term, virtual\n machine that executes byte codes to inspect packet or metadata\n (arriving interface index, etc.) and make verdict decisions.\n\n Besides support for loading packet contents and comparing them, the\n interpreter supports lookups in various datastructures as\n fundamental operations. For example sets are supports, and\n therefore one could create a set of whitelist IP address entries\n which have ACCEPT verdicts attached to them, and use the appropriate\n byte codes to do such lookups.\n\n Since the interpreted code is composed in userspace, userspace can\n do things like optimize things before giving it to the kernel.\n\n Another major improvement is the capability of atomically updating\n portions of the ruleset. In the existing netfilter implementation,\n one has to update the entire rule set in order to make a change and\n this is very expensive.\n\n Userspace tools exist to create nftables rules using existing\n netfilter rule sets, but both kernel implementations will need to\n co-exist for quite some time as we transition from the old to the\n new stuff.\n\n Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have\n worked so hard on this.\n\n 2) Daniel Borkmann and Hannes Frederic Sowa made several improvements\n to our pseudo-random number generator, mostly used for things like\n UDP port randomization and netfitler, amongst other things.\n\n In particular the taus88 generater is updated to taus113, and test\n cases are added.\n\n 3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet\n and Yang Yingliang.\n\n 4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin\n Sujir.\n\n 5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet,\n Neal Cardwell, and Yuchung Cheng.\n\n 6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary\n control message data, much like other socket option attributes.\n From Francesco Fusco.\n\n 7) Allow applications to specify a cap on the rate computed\n automatically by the kernel for pacing flows, via a new\n SO_MAX_PACING_RATE socket option. From Eric Dumazet.\n\n 8) Make the initial autotuned send buffer sizing in TCP more closely\n reflect actual needs, from Eric Dumazet.\n\n 9) Currently early socket demux only happens for TCP sockets, but we\n can do it for connected UDP sockets too. Implementation from Shawn\n Bohrer.\n\n10) Refactor inet socket demux with the goal of improving hash demux\n performance for listening sockets. With the main goals being able\n to use RCU lookups on even request sockets, and eliminating the\n listening lock contention. From Eric Dumazet.\n\n11) The bonding layer has many demuxes in it\u0027s fast path, and an RCU\n conversion was started back in 3.11, several changes here extend the\n RCU usage to even more locations. From Ding Tianhong and Wang\n Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav\n Falico.\n\n12) Allow stackability of segmentation offloads to, in particular, allow\n segmentation offloading over tunnels. From Eric Dumazet.\n\n13) Significantly improve the handling of secret keys we input into the\n various hash functions in the inet hashtables, TCP fast open, as\n well as syncookies. From Hannes Frederic Sowa. The key fundamental\n operation is \"net_get_random_once()\" which uses static keys.\n\n Hannes even extended this to ipv4/ipv6 fragmentation handling and\n our generic flow dissector.\n\n14) The generic driver layer takes care now to set the driver data to\n NULL on device removal, so it\u0027s no longer necessary for drivers to\n explicitly set it to NULL any more. Many drivers have been cleaned\n up in this way, from Jingoo Han.\n\n15) Add a BPF based packet scheduler classifier, from Daniel Borkmann.\n\n16) Improve CRC32 interfaces and generic SKB checksum iterators so that\n SCTP\u0027s checksumming can more cleanly be handled. Also from Daniel\n Borkmann.\n\n17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces\n using the interface MTU value. This helps avoid PMTU attacks,\n particularly on DNS servers. From Hannes Frederic Sowa.\n\n18) Use generic XPS for transmit queue steering rather than internal\n (re-)implementation in virtio-net. From Jason Wang.\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1622 commits)\n random32: add test cases for taus113 implementation\n random32: upgrade taus88 generator to taus113

This conversion is affected by integer math rounding loss, so\nthe backwards conversion to hardware ticks will likely result in a\nvalue which is less than the configured hardware limitation. The\naffected subarchs used their own workaround (SIGH!) which got lost in\nthe conversion.\n\nThe solution for the issue at hand is simple: adding evt-\u003emult - 1 to\nthe shifted value before the integer divison in the core conversion\nfunction takes care of it. But this only works for the case where for\nthe scaled math mult/shift pair \"mult \u003c\u003d 1 \u003c\u003c shift\" is true. For the\ncase where \"mult \u003e 1 \u003c\u003c shift\" we can apply the rounding add only for\nthe minimum delta value to make sure that the backward conversion is\nnot less than the given hardware limit. For the upper bound we need to\nomit the rounding add, because the backwards conversion is always\nlarger than the original latch value. That would violate the upper\nbound of the hardware device.\n\nThough looking closer at the details of that function reveals another\nbogosity: The upper bounds check is broken as well. Checking for a\nresulting \"clc\" value greater than KTIME_MAX after the conversion is\npointless. The conversion does:\n\n u64 clc \u003d (latch \u003c\u003c evt-\u003eshift) / evt-\u003emult;\n\nSo there is no sanity check for (latch \u003c\u003c evt-\u003eshift) exceeding the\n64bit boundary. The latch argument is \"unsigned long\", so on a 64bit\narch the handed in argument could easily lead to an unnoticed shift\noverflow. With the above rounding fix applied the calculation before\nthe divison is:\n\n u64 clc \u003d (latch \u003c\u003c evt-\u003eshift) + evt-\u003emult - 1;\n\nSo we need to make sure, that neither the shift nor the rounding add\nis overflowing the u64 boundary.\n\n[ukl: move assignment to rnd after eventually changing mult, fix build\n issue and correct comment with the right math]\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Russell King - ARM Linux \u003clinux@arm.linux.org.uk\u003e\nCc: Marc Kleine-Budde \u003cmkl@pengutronix.de\u003e\nCc: nicolas.ferre@atmel.com\nCc: Marc Pignat \u003cmarc.pignat@hevs.ch\u003e\nCc: john.stultz@linaro.org\nCc: kernel@pengutronix.de\nCc: Ronald Wahl \u003cronald.wahl@raritan.com\u003e\nCc: LAK \u003clinux-arm-kernel@lists.infradead.org\u003e\nCc: Ludovic Desroches \u003cludovic.desroches@atmel.com\u003e\nCc: stable@vger.kernel.org\nLink: http://lkml.kernel.org/r/1380052223-24139-1-git-send-email-u.kleine-koenig@pengutronix.de\nSigned-off-by: Uwe Kleine-König \u003cu.kleine-koenig@pengutronix.de\u003e\n" }, { "commit": "ee7eafc907db64ef4cbe8a17da3a1089cbe50617", "tree": "448cfbb1827083f875729135d4ab0d00b0f0752b", "parents": [ "0df651a0740c9663093265277c32f0806e8ac23e", "ea84753c98a7ac6b74e530b64c444a912b3835ca" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Oct 22 08:20:34 2013 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Oct 22 08:20:34 2013 +0100" }, "message": "Merge branch \u0027for-3.12-fixes\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup\n\nPull cgroup fixes from Tejun Heo:\n \"Two late fixes for cgroup.\n\n One fixes descendant walk introduced during this rc1 cycle.
