testing\n\nThis is a pair of test modules I\u0027d like to see in the tree. Instead of\nputting these in lkdtm, where I\u0027ve been adding various tests that trigger\ncrashes, these don\u0027t make sense there since they need to be either\ndistinctly separate, or their pass/fail state don\u0027t need to crash the\nmachine.\n\nThese live in lib/ for now, along with a few other in-kernel test modules,\nand use the slightly more common \"test_\" naming convention, instead of\n\"test-\". We should likely standardize on the former:\n\n$ find . -name \u0027test_*.c\u0027 | grep -v /tools/ | wc -l\n4\n$ find . -name \u0027test-*.c\u0027 | grep -v /tools/ | wc -l\n2\n\nThe first is entirely a no-op module, designed to allow simple testing of\nthe module loading and verification interface. It\u0027s useful to have a\nmodule that has no other uses or dependencies so it can be reliably used\nfor just testing module loading and verification.\n\nThe second is a module that exercises the user memory access functions, in\nan effort to make sure that we can quickly catch any regressions in\nboundary checking (e.g. like what was recently fixed on ARM).\n\nThis patch (of 2):\n\nWhen doing module loading verification tests (for example, with module\nsigning, or LSM hooks), it is very handy to have a module that can be\nbuilt on all systems under test, isn\u0027t auto-loaded at boot, and has no\ndevice or similar dependencies. This creates the \"test_module.ko\" module\nfor that purpose, which only reports its load and unload to printk.\n\nSigned-off-by: Kees Cook \u003ckeescook@chromium.org\u003e\nAcked-by: Rusty Russell

This follow-up patch\nimproves reciprocal_value() and reciprocal_divide() to work in\nall cases by using Granlund and Montgomery method, so that also\nfuture use is safe and without any non-obvious side-effects.\nKnown problems with the old implementation were that division by 1\nalways returned 0 and some off-by-ones when the dividend and divisor\nwhere very large. This seemed to not be problematic with its\ncurrent users, as far as we can tell. Eric Dumazet checked for\nthe slab usage, we cannot surely say so in the case of flex_array.\nStill, in order to fix that, we propose an extension from the\noriginal implementation from commit 6a2d7a955d8d resp. [3][4],\nby using the algorithm proposed in \"Division by Invariant Integers\nUsing Multiplication\" [5], Torbjörn Granlund and Peter L.\nMontgomery, that is, pseudocode for q \u003d n/d where q, n, d is in\nu32 universe:\n\n1) Initialization:\n\n int l \u003d ceil(log_2 d)\n uword m\u0027 \u003d floor((1\u003c\u003c32)*((1\u003c\u003cl)-d)/d)+1\n int sh_1 \u003d min(l,1)\n int sh_2 \u003d max(l-1,0)\n\n2) For q \u003d n/d, all uword:\n\n uword t \u003d (n*m\u0027)\u003e\u003e32\n q \u003d (t+((n-t)\u003e\u003esh_1))\u003e\u003esh_2\n\nThe assembler implementation from Agner Fog [6] also helped a lot\nwhile implementing. We have tested the implementation on x86_64,\nppc64, i686, s390x; on x86_64/haswell we\u0027re still half the latency\ncompared to normal divide.\n\nJoint work with Daniel Borkmann.\n\n [1] http://www.wireshark.org/~darkjames/reciprocal-buggy.c\n [2] http://www.wireshark.org/~darkjames/set-and-dump-filter-k-bug.c\n [3] https://gmplib.org/~tege/division-paper.pdf\n [4] http://homepage.cs.uiowa.edu/~jones/bcd/divide.html\n [5] http://citeseerx.ist.psu.edu/viewdoc/summary?doi\u003d10.1.1.1.2556\n [6] http://www.agner.org/optimize/asmlib.zip\n\nReported-by: Jakub Zawadzki \u003cdarkjames-ws@darkjames.pl\u003e\nCc: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCc: Austin S Hemmelgarn \u003cahferroin7@gmail.com\u003e\nCc: linux-kernel@vger.kernel.org\nCc: Jesse Gross \u003cjesse@nicira.com\u003e\nCc: Jamal Hadi Salim \u003cjhs@mojatatu.com\u003e\nCc: Stephen Hemminger \u003cstephen@networkplumber.org\u003e\nCc: Matt Mackall \u003cmpm@selenic.com\u003e\nCc: Pekka Enberg \u003cpenberg@kernel.org\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Andy Gospodarek \u003candy@greyhouse.net\u003e\nCc: Veaceslav Falico \u003cvfalico@redhat.com\u003e\nCc: Jay Vosburgh \u003cfubar@us.ibm.com\u003e\nCc: Jakub Zawadzki \u003cdarkjames-ws@darkjames.pl\u003e\nSigned-off-by: Daniel Borkmann \u003cdborkman@redhat.com\u003e\nSigned-off-by: Hannes Frederic Sowa \u003channes@stressinduktion.org\u003e\nSigned-off-by: David S.

There are a number of separate bits. I\u0027ll go over the big bits\n and the odd important other bit, most of the smaller bits are just\n fixes and cleanups. If you want the small bits accounting for, I can\n do that too.\n\n (1) Keyring capacity expansion.\n\n KEYS: Consolidate the concept of an \u0027index key\u0027 for key access\n KEYS: Introduce a search context structure\n KEYS: Search for auth-key by name rather than target key ID\n Add a generic associative array implementation.\n KEYS: Expand the capacity of a keyring\n\n Several of the patches are providing an expansion of the capacity of a\n keyring. Currently, the maximum size of a keyring payload is one page.\n Subtract a small header and then divide up into pointers, that only gives\n you ~500 pointers on an x86_64 box. However, since the NFS idmapper uses\n a keyring to store ID mapping data, that has proven to be insufficient to\n the cause.\n\n Whatever data structure I use to handle the keyring payload, it can only\n store pointers to keys, not the keys themselves because several keyrings\n may point to a single key. This precludes inserting, say, and rb_node\n struct into the key struct for this purpose.\n\n I could make an rbtree of records such that each record has an rb_node\n and a key pointer, but that would use four words of space per key stored\n in the keyring. It would, however, be able to use much existing code.\n\n I selected instead a non-rebalancing radix-tree type approach as that\n could have a better space-used/key-pointer ratio. I could have used the\n radix tree implementation that we already have and insert keys into it by\n their serial numbers, but that means any sort of search must iterate over\n the whole radix tree. Further, its nodes are a bit on the capacious side\n for what I want - especially given that key serial numbers are randomly\n allocated, thus leaving a lot of empty space in the tree.\n\n So what I have is an associative array that internally is a radix-tree\n with 16 pointers per node where the index key is constructed from the key\n type pointer and the key description. This means that an exact lookup by\n type+description is very fast as this tells us how to navigate directly to\n the target key.\n\n I made the data structure general in lib/assoc_array.c as far as it is\n concerned, its index key is just a sequence of bits that leads to a\n pointer. It\u0027s possible that someone else will be able to make use of it\n also. FS-Cache might, for example.\n\n (2) Mark keys as \u0027trusted\u0027 and keyrings as \u0027trusted only\u0027.\n\n KEYS: verify a certificate is signed by a \u0027trusted\u0027 key\n KEYS: Make the system \u0027trusted\u0027 keyring viewable by userspace\n KEYS: Add a \u0027trusted\u0027 flag and a \u0027trusted only\u0027 flag\n KEYS: Separate the kernel signature checking keyring from module signing\n\n These patches allow keys carrying asymmetric public keys to be marked as\n being \u0027trusted\u0027 and allow keyrings to be marked as only permitting the\n addition or linkage of trusted keys.\n\n Keys loaded from hardware during kernel boot or compiled into the kernel\n during build are marked as being trusted automatically. New keys can be\n loaded at runtime with add_key(). They are checked against the system\n keyring contents and if their signatures can be validated with keys that\n are already marked trusted, then they are marked trusted also and can\n thus be added into the master keyring.\n\n Patches from Mimi Zohar make this usable with the IMA keyrings also.\n\n (3) Remove the date checks on the key used to validate a module signature.\n\n X.509: Remove certificate date checks\n\n It\u0027s not reasonable to reject a signature just because the key that it was\n generated with is no longer valid datewise - especially if the kernel\n hasn\u0027t yet managed to set the system clock when the first module is\n loaded - so just remove those checks.\n\n (4) Make it simpler to deal with additional X.509 being loaded into the kernel.\n\n KEYS: Load *.x509 files into kernel keyring\n KEYS: Have make canonicalise the paths of the X.509 certs better to deduplicate\n\n The builder of the kernel now just places files with the extension \".x509\"\n into the kernel source or build trees and they\u0027re concatenated by the\n kernel build and stuffed into the appropriate section.\n\n (5) Add support for userspace kerberos to use keyrings.\n\n KEYS: Add per-user_namespace registers for persistent per-UID kerberos caches\n KEYS: Implement a big key type that can save to tmpfs\n\n Fedora went to, by default, storing kerberos tickets and tokens in tmpfs.\n We looked at storing it in keyrings instead as that confers certain\n advantages such as tickets being automatically deleted after a certain\n amount of time and the ability for the kernel to get at these tokens more\n easily.\n\n To make this work, two things were needed:\n\n (a) A way for the tickets to persist beyond the lifetime of all a user\u0027s\n sessions so that cron-driven processes can still use them.\n\n The problem is that a user\u0027s session keyrings are deleted when the\n session that spawned them logs out and the user\u0027s user keyring is\n deleted when the UID is deleted (typically when the last log out\n happens), so neither of these places is suitable.\n\n I\u0027ve added a system keyring into which a \u0027persistent\u0027 keyring is\n created for each UID on request. Each time a user requests their\n persistent keyring, the expiry time on it is set anew. If the user\n doesn\u0027t ask for it for, say, three days, the keyring is automatically\n expired and garbage collected using the existing gc. All the kerberos\n tokens it held are then also gc\u0027d.\n\n (b) A key type that can hold really big tickets (up to 1MB in size).\n\n The problem is that Active Directory can return huge tickets with lots\n of auxiliary data attached. We don\u0027t, however, want to eat up huge\n tracts of unswappable kernel space for this, so if the ticket is\n greater than a certain size, we create a swappable shmem file and dump\n the contents in there and just live with the fact we then have an\n inode and a dentry overhead. If the ticket is smaller than that, we\n slap it in a kmalloc()\u0027d buffer\"\n\n* \u0027for-linus2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (121 commits)\n KEYS: Fix keyring content gc scanner\n KEYS: Fix error handling in big_key instantiation\n KEYS: Fix UID check in keyctl_get_persistent()\n KEYS: The RSA public key algorithm needs to select MPILIB\n ima: define \u0027_ima\u0027 as a builtin \u0027trusted\u0027 keyring\n ima: extend the measurement list to include the file signature\n kernel/system_certificate.S: use real contents instead of macro GLOBAL()\n KEYS: fix error return code in big_key_instantiate()\n KEYS: Fix keyring quota misaccounting on key replacement and unlink\n KEYS: Fix a race between negating a key and reading the error set\n KEYS: Make BIG_KEYS boolean\n apparmor: remove the \"task\" arg from may_change_ptraced_domain()\n apparmor: remove parent task info from audit logging\n apparmor: remove tsk field from the apparmor_audit_struct\n apparmor: fix capability to not use the current task, during reporting\n Smack: Ptrace access check mode\n ima: provide hash algo info in the xattr\n ima: enable support for larger default filedata hash algorithms\n ima: define kernel parameter \u0027ima_template\u003d\u0027 to change configured default\n ima: add Kconfig default measurement list template\n ...\n" }, { "commit": "fcd40d69afea8700eda8cbf381f6d160cf757ebf", "tree": "d7b8df5316ea68517078a0ffdc449de3a32ae2cc", "parents": [ "ea7e32bec1b9d9e5b159d80ceb563c702e28b02a" ], "author": { "name": "Randy Dunlap", "email": "rdunlap@infradead.org", "time": "Tue Nov 19 10:08:13 2013 -0800" }, "committer": { "name": "Nicholas Bellinger", "email": "nab@linux-iscsi.org", "time": "Tue Nov 19 21:39:21 2013 -0800" }, "message": "percpu-refcount: Add percpu-refcount.o to obj-y\n\nDrop percpu_ida.o from lib-y since it is also listed in obj-y\nand it doesn\u0027t need to be listed in both places.\n\nMove percpu-refcount.o from lib-y to obj-y to fix build errors\nin target_core_mod:\n\nERROR: \"percpu_ref_cancel_init\" [drivers/target/target_core_mod.ko] undefined!\nERROR: \"percpu_ref_kill_and_confirm\" [drivers/target/target_core_mod.ko] undefined!\nERROR: \"percpu_ref_init\" [drivers/target/target_core_mod.ko] undefined!\n\nSigned-off-by: Randy Dunlap \u003crdunlap@infradead.org\u003e\nSigned-off-by: Nicholas Bellinger \u003cnab@linux-iscsi.org\u003e\n" }, { "commit": "1ee2dcc2245340cf4ac94b99c4d00efbeba61824", "tree": "5339e55add987379525177011dde6e3756b1430c", "parents": [ "4457e6f6c9f6052cd5f44a79037108b5ddeb0ce7", "091e0662ee2c37867ad918ce7b6ddd17f0e090e2" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Nov 19 15:50:47 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Nov 19 15:50:47 2013 -0800" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net\n\nPull networking fixes from David Miller:\n \"Mostly these are fixes for fallout due to merge window changes, as\n well as cures for problems that have been with us for a much longer\n period of time\"\n\n 1) Johannes Berg noticed two major deficiencies in our genetlink\n registration.

From Alexei Starovoitov.\n\n 5) Bridge erroneously fails to use the proper wrapper functions to make\n calls to netdev_ops-\u003endo_vlan_rx_{add,kill}_vid. Fix from Toshiaki\n Makita.\n\n 6) When detaching a bridge port, make sure to flush all VLAN IDs to\n prevent them from leaking, also from Toshiaki Makita.\n\n 7) Put in a compromise for TCP Small Queues so that deep queued devices\n that delay TX reclaim non-trivially don\u0027t have such a performance\n decrease. One particularly problematic area is 802.11 AMPDU in\n wireless. From Eric Dumazet.\n\n 8) Fix crashes in tcp_fastopen_cache_get(), we can see NULL socket dsts\n here. Fix from Eric Dumzaet, reported by Dave Jones.\n\n 9) Fix use after free in ipv6 SIT driver, from Willem de Bruijn.\n\n10) When computing mergeable buffer sizes, virtio-net fails to take the\n virtio-net header into account. From Michael Dalton.\n\n11) Fix seqlock deadlock in ip4_datagram_connect() wrt. statistic\n bumping, this one has been with us for a while. From Eric Dumazet.\n\n12) Fix NULL deref in the new TIPC fragmentation handling, from Erik\n Hugne.\n\n13) 6lowpan bit used for traffic classification was wrong, from Jukka\n Rissanen.\n\n14) macvlan has the same issue as normal vlans did wrt. propagating LRO\n disabling down to the real device, fix it the same way. From Michal\n Kubecek.\n\n15) CPSW driver needs to soft reset all slaves during suspend, from\n Daniel Mack.\n\n16) Fix small frame pacing in FQ packet scheduler, from Eric Dumazet.\n\n17) The xen-netfront RX buffer refill timer isn\u0027t properly scheduled on\n partial RX allocation success, from Ma JieYue.\n\n18) When ipv6 ping protocol support was added, the AF_INET6 protocol\n initialization cleanup path on failure was borked a little. Fix\n from Vlad Yasevich.\n\n19) If a socket disconnects during a read/recvmsg/recvfrom/etc that\n blocks we can do the wrong thing with the msg_name we write back to\n userspace. From Hannes Frederic Sowa. There is another fix in the\n works from Hannes which will prevent future problems of this nature.\n\n20) Fix route leak in VTI tunnel transmit, from Fan Du.\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (106 commits)\n genetlink: make multicast groups const, prevent abuse\n genetlink: pass family to functions using groups\n genetlink: add and use genl_set_err()\n genetlink: remove family pointer from genl_multicast_group\n genetlink: remove genl_unregister_mc_group()\n hsr: don\u0027t call genl_unregister_mc_group()\n quota/genetlink: use proper genetlink multicast APIs\n drop_monitor/genetlink: use proper genetlink multicast APIs\n genetlink: only pass array to genl_register_family_with_ops()\n tcp: don\u0027t update snd_nxt, when a socket is switched from repair mode\n atm: idt77252: fix dev refcnt leak\n xfrm: Release dst if this dst is improper for vti tunnel\n netlink: fix documentation typo in netlink_set_err()\n be2net: Delete secondary unicast MAC addresses during be_close\n be2net: Fix unconditional enabling of Rx interface options\n net, virtio_net: replace the magic value\n ping: prevent NULL pointer dereference on write to msg_name\n bnx2x: Prevent \"timeout waiting for state X\"\n bnx2x: prevent CFC attention\n bnx2x: Prevent panic during DMAE timeout\n ...\n" }, { "commit": "eda670c626a4f53eb8ac5f20d8c10d3f0b54c583", "tree": "e8b31fdeddd520b0fc56483f0a33c0501ee3b692", "parents": [ "b746f9c7941f227ad582b4f0bc981f3adcbc46b2", "18c51e1a3fabb455ff1f5cd610097d89f577b8f7" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Nov 15 13:34:37 2013 +0900" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Nov 15 13:34:37 2013 +0900" }, "message": "Merge tag \u0027stable/for-linus-3.13-rc0-tag\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip\n\nPull Xen updates from Konrad Rzeszutek Wilk:\n \"This has tons of fixes and two major features which are concentrated\n around the Xen SWIOTLB library.\n\n The short \u003cblurb\u003e is that the tracing facility (just one function) has\n been added to SWIOTLB to make it easier to track I/O progress.\n Additionally under Xen and ARM (32 \u0026 64) the Xen-SWIOTLB driver\n \"is used to translate physical to machine and machine to physical\n addresses of foreign[guest] pages for DMA operations\" (Stefano) when\n booting under hardware without proper IOMMU.\n\n There are also bug-fixes, cleanups, compile warning fixes, etc.\n\n The commit times for some of the commits is a bit fresh - that is b/c\n we wanted to make sure we have the Ack\u0027s from the ARM folks - which\n with the string of back-to-back conferences took a bit of time.

It contains:\n\n - The new blk-mq request interface.\n\n This is a new and more scalable queueing model that marries the\n best part of the request based interface we currently have (which\n is fully featured, but scales poorly) and the bio based \"interface\"\n which the new drivers for high IOPS devices end up using because\n it\u0027s much faster than the request based one.\n\n The bio interface has no block layer support, since it taps into\n the stack much earlier. This means that drivers end up having to\n implement a lot of functionality on their own, like tagging,\n timeout handling, requeue, etc. The blk-mq interface provides all\n these. Some drivers even provide a switch to select bio or rq and\n has code to handle both, since things like merging only works in\n the rq model and hence is faster for some workloads. This is a\n huge mess. Conversion of these drivers nets us a substantial code\n reduction. Initial results on converting SCSI to this model even\n shows an 8x improvement on single queue devices. So while the\n model was intended to work on the newer multiqueue devices, it has\n substantial improvements for \"classic\" hardware as well. This code\n has gone through extensive testing and development, it\u0027s now ready\n to go. A pull request is coming to convert virtio-blk to this\n model will be will be coming as well, with more drivers scheduled\n for 3.14 conversion.\n\n - Two blktrace fixes from Jan and Chen Gang.\n\n - A plug merge fix from Alireza Haghdoost.\n\n - Conversion of __get_cpu_var() from Christoph Lameter.\n\n - Fix for sector_div() with 64-bit divider from Geert Uytterhoeven.\n\n - A fix for a race between request completion and the timeout\n handling from Jeff Moyer. This is what caused the merge conflict\n with blk-mq/core, in case you are looking at that.\n\n - A dm stacking fix from Mike Snitzer.\n\n - A code consolidation fix and duplicated code removal from Kent\n Overstreet.\n\n - A handful of block bug fixes from Mikulas Patocka, fixing a loop\n crash and memory corruption on blk cg.\n\n - Elevator switch bug fix from Tomoki Sekiyama.\n\n A heads-up that I had to rebase this branch.

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.

The\nalgorithm is presented in [1] by the very same author who also\ndesigned the original algorithm in [2].\n\nAlso, by increasing the state, we make it a bit harder for attackers\nto \"guess\" the PRNGs internal state. See also discussion in [3].\n\nNow, as we use this sort of weak initialization discussed in [3]\nonly between core_initcall() until late_initcall() time [*] for\nprandom32*() users, namely in prandom_init(), it is less relevant\nfrom late_initcall() onwards as we overwrite seeds through\nprandom_reseed() anyways with a seed source of higher entropy, that\nis, get_random_bytes(). In other words, a exhaustive keysearch of\n96 bit would be needed. Now, with the help of this patch, this\nstate-search increases further to 128 bit. Initialization needs\nto make sure that s1 \u003e 1, s2 \u003e 7, s3 \u003e 15, s4 \u003e 127.\n\ntaus88 and taus113 algorithm is also part of GSL. I added a test\ncase in the next patch to verify internal behaviour of this patch\nwith GSL and ran tests with the dieharder 3.31.1 RNG test suite:\n\n$ dieharder -g 052 -a -m 10 -s 1 -S 4137730333 #taus88\n$ dieharder -g 054 -a -m 10 -s 1 -S 4137730333 #taus113\n\nWith this seed configuration, in order to compare both, we get\nthe following differences:\n\nalgorithm taus88 taus113\nrands/second [**] 1.61e+08 1.37e+08\nsts_serial(4, 1st run) WEAK PASSED\nsts_serial(9, 2nd run) WEAK PASSED\nrgb_lagged_sum(31) WEAK PASSED\n\nWe took out diehard_sums test as according to the authors it is\nconsidered broken and unusable [4]. Despite that and the slight\ndecrease in performance (which is acceptable), taus113 here passes\nall 113 tests (only rgb_minimum_distance_5 in WEAK, the rest PASSED).\nIn general, taus/taus113 is considered \"very good\" by the authors\nof dieharder [5].\n\nThe papers [1][2] states a single warm-up step is sufficient by\nrunning quicktaus once on each state to ensure proper initialization\nof ~s_{0}:\n\nOur selection of (s) according to Table 1 of [1] row 1 holds the\ncondition L - k \u003c\u003d r - s, that is,\n\n (32 32 32 32) - (31 29 28 25) \u003c\u003d (25 27 15 22) - (18 2 7 13)\n\nwith r \u003d k - q and q \u003d (6 2 13 3) as also stated by the paper.\nSo according to [2] we are safe with one round of quicktaus for\ninitialization. However we decided to include the warm-up phase\nof the PRNG as done in GSL in every case as a safety net. We also\nuse the warm up phase to make the output of the RNG easier to\nverify by the GSL output.\n\nIn prandom_init(), we also mix random_get_entropy() into it, just\nlike drivers/char/random.c does it, jiffies ^ random_get_entropy().\nrandom-get_entropy() is get_cycles(). xor is entropy preserving so\nit is fine if it is not implemented by some architectures.\n\nNote, this PRNG is *not* used for cryptography in the kernel, but\nrather as a fast PRNG for various randomizations i.e. in the\nnetworking code, or elsewhere for debugging purposes, for example.\n\n[*]: In order to generate some \"sort of pseduo-randomness\", since\nget_random_bytes() is not yet available for us, we use jiffies and\ninitialize states s1 - s3 with a simple linear congruential generator\n(LCG), that is x \u003c- x * 69069; and derive s2, s3, from the 32bit\ninitialization from s1. So the above quote from [3] accounts only\nfor the time from core to late initcall, not afterwards.\n[**] Single threaded run on MacBook Air w/ Intel Core i5-3317U\n\n [1] http://www.iro.umontreal.ca/~lecuyer/myftp/papers/tausme2.ps\n [2] http://www.iro.umontreal.ca/~lecuyer/myftp/papers/tausme.ps\n [3] http://thread.gmane.org/gmane.comp.encryption.general/12103/\n [4] http://code.google.com/p/dieharder/source/browse/trunk/libdieharder/diehard_sums.c?spec\u003dsvn490\u0026r\u003d490#20\n [5] http://www.phy.duke.edu/~rgb/General/dieharder.php\n\nJoint work with Hannes Frederic Sowa.\n\nCc: Florian Weimer \u003cfweimer@redhat.com\u003e\nCc: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\nSigned-off-by: Daniel Borkmann \u003cdborkman@redhat.com\u003e\nSigned-off-by: Hannes Frederic Sowa \u003channes@stressinduktion.org\u003e\nSigned-off-by: David S.
