RFS steers\nreceived packets for layer 3 and 4 processing to the CPU where\nthe application for the corresponding flow is running. RFS is an\nextension of Receive Packet Steering (RPS).\n\nThe basic idea of RFS is that when an application calls recvmsg\n(or sendmsg) the application\u0027s running CPU is stored in a hash\ntable that is indexed by the connection\u0027s rxhash which is stored in\nthe socket structure. The rxhash is passed in skb\u0027s received on\nthe connection from netif_receive_skb. For each received packet,\nthe associated rxhash is used to look up the CPU in the hash table,\nif a valid CPU is set then the packet is steered to that CPU using\nthe RPS mechanisms.\n\nThe convolution of the simple approach is that it would potentially\nallow OOO packets. If threads are thrashing around CPUs or multiple\nthreads are trying to read from the same sockets, a quickly changing\nCPU value in the hash table could cause rampant OOO packets--\nwe consider this a non-starter.\n\nTo avoid OOO packets, this solution implements two types of hash\ntables: rps_sock_flow_table and rps_dev_flow_table.\n\nrps_sock_table is a global hash table. Each entry is just a CPU\nnumber and it is populated in recvmsg and sendmsg as described above.\nThis table contains the \"desired\" CPUs for flows.\n\nrps_dev_flow_table is specific to each device queue. Each entry\ncontains a CPU and a tail queue counter. The CPU is the \"current\"\nCPU for a matching flow. The tail queue counter holds the value\nof a tail queue counter for the associated CPU\u0027s backlog queue at\nthe time of last enqueue for a flow matching the entry.\n\nEach backlog queue has a queue head counter which is incremented\non dequeue, and so a queue tail counter is computed as queue head\ncount + queue length. When a packet is enqueued on a backlog queue,\nthe current value of the queue tail counter is saved in the hash\nentry of the rps_dev_flow_table.\n\nAnd now the trick: when selecting the CPU for RPS (get_rps_cpu)\nthe rps_sock_flow table and the rps_dev_flow table for the RX queue\nare consulted. When the desired CPU for the flow (found in the\nrps_sock_flow table) does not match the current CPU (found in the\nrps_dev_flow table), the current CPU is changed to the desired CPU\nif one of the following is true:\n\n- The current CPU is unset (equal to RPS_NO_CPU)\n- Current CPU is offline\n- The current CPU\u0027s queue head counter \u003e\u003d queue tail counter in the\nrps_dev_flow table. This checks if the queue tail has advanced\nbeyond the last packet that was enqueued using this table entry.\nThis guarantees that all packets queued using this entry have been\ndequeued, thus preserving in order delivery.\n\nMaking each queue have its own rps_dev_flow table has two advantages:\n1) the tail queue counters will be written on each receive, so\nkeeping the table local to interrupting CPU s good for locality. 2)\nthis allows lockless access to the table-- the CPU number and queue\ntail counter need to be accessed together under mutual exclusion\nfrom netif_receive_skb, we assume that this is only called from\ndevice napi_poll which is non-reentrant.\n\nThis patch implements RFS for TCP and connected UDP sockets.\nIt should be usable for other flow oriented protocols.\n\nThere are two configuration parameters for RFS. The\n\"rps_flow_entries\" kernel init parameter sets the number of\nentries in the rps_sock_flow_table, the per rxqueue sysfs entry\n\"rps_flow_cnt\" contains the number of entries in the rps_dev_flow\ntable for the rxqueue. Both are rounded to power of two.\n\nThe obvious benefit of RFS (over just RPS) is that it achieves\nCPU locality between the receive processing for a flow and the\napplications processing; this can result in increased performance\n(higher pps, lower latency).\n\nThe benefits of RFS are dependent on cache hierarchy, application\nload, and other factors. On simple benchmarks, we don\u0027t necessarily\nsee improvement and sometimes see degradation. However, for more\ncomplex benchmarks and for applications where cache pressure is\nmuch higher this technique seems to perform very well.\n\nBelow are some benchmark results which show the potential benfit of\nthis patch. The netperf test has 500 instances of netperf TCP_RR\ntest with 1 byte req. and resp. The RPC test is an request/response\ntest similar in structure to netperf RR test ith 100 threads on\neach host, but does more work in userspace that netperf.\n\ne1000e on 8 core Intel\n No RFS or RPS\t\t104K tps at 30% CPU\n No RFS (best RPS config): 290K tps at 63% CPU\n RFS\t\t\t\t303K tps at 61% CPU\n\nRPC test\ttps\tCPU%\t50/90/99% usec latency\tLatency StdDev\n No RFS/RPS\t103K\t48%\t757/900/3185\t\t4472.35\n RPS only:\t174K\t73%\t415/993/2468\t\t491.66\n RFS\t\t223K\t73%\t379/651/1382\t\t315.61\n\nSigned-off-by: Tom Herbert \u003ctherbert@google.com\u003e\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: David S.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "a3a858ff18a72a8d388e31ab0d98f7e944841a62", "tree": "e51a59ce280f0aa818ac5e1d989bc8a137b7cd47", "parents": [ "2499849ee8f513e795b9f2c19a42d6356e4943a4" ], "author": { "name": "Zhu Yi", "email": "yi.zhu@intel.com", "time": "Thu Mar 04 18:01:47 2010 +0000" }, "committer": { "name": "David S.

This value was\nexported via a SOL_PACKET level cmsg. AFter I completed that work it was\nrequested that this feature be generalized so that any datagram oriented socket\ncould make use of this option. As such I\u0027ve created this patch, It creates a\nnew SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a\nSOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue\noverflowed between any two given frames. It also augments the AF_PACKET\nprotocol to take advantage of this new feature (as it previously did not touch\nsk-\u003esk_drops, which this patch uses to record the overflow count). Tested\nsuccessfully by me.\n\nNotes:\n\n1) Unlike my previous patch, this patch simply records the sk_drops value, which\nis not a number of drops between packets, but rather a total number of drops.\nDeltas must be computed in user space.\n\n2) While this patch currently works with datagram oriented protocols, it will\nalso be accepted by non-datagram oriented protocols. I\u0027m not sure if thats\nagreeable to everyone, but my argument in favor of doing so is that, for those\nprotocols which aren\u0027t applicable to this option, sk_drops will always be zero,\nand reporting no drops on a receive queue that isn\u0027t used for those\nnon-participating protocols seems reasonable to me. This also saves us having\nto code in a per-protocol opt in mechanism.\n\n3) This applies cleanly to net-next assuming that commit\n977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: David S.
