The typo is due to swap of local/remote addresses.\n\nConsider __raw_v6_lookup() function from net/ipv6/raw.c. When a raw socket is\nlooked up usual way, it is something like:\n\nsk \u003d __raw_v6_lookup(sk, nexthdr, daddr, saddr, IP6CB(skb)-\u003eiif);\n\nwhere \"daddr\" is a destination address of the incoming packet (IOW our local\naddress), \"saddr\" is a source address of the incoming packet (the remote end).\n\nBut when the raw socket is looked up for some icmp error report, in\nnet/ipv6/icmp.c:icmpv6_notify() , daddr/saddr are obtained from the echoed\nfragment of the \"bad\" packet, i.e. \"daddr\" is the original destination\naddress of that packet, \"saddr\" is our local address. Hence, for\nicmpv6_notify() must use \"saddr, daddr\" in its arguments, not \"daddr, saddr\"\n...\n\nSteps to reproduce:\n\nCreate some raw socket, connect it to an address, and cause some error\nsituation: f.e. set ttl\u003d1 where the remote address is more than 1 hop to reach.\nSet IPV6_RECVERR .\nThen send something and wait for the error (f.e. poll() with POLLERR|POLLIN).\nYou should receive \"time exceeded\" icmp message (because of \"ttl\u003d1\"), but the\nsocket do not receive it.\n\nIf you do not connect your raw socket, you will receive MSG_ERRQUEUE\nsuccessfully. (The reason is that for unconnected socket there are no actual\nchecks for local/remote addresses).\n\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: David S.

For real hardware drivers that just\ncommit all changes to the hardware this is not a real problem since\nthe stack guarantees to call them for every change, so at least the\nfinal call will not race and commit the correct configuration to the\nhardware.\n\nFor software devices that want to synchronize promiscous and multicast\nstate to an underlying device however this can cause corruption of the\nunderlying device\u0027s flags or promisc/allmulti counts.\n\nWhen the software device is concurrently put in promiscous or allmulti\nmode while set_multicast_list is invoked from bottem half context, the\ndevice might synchronize the change to the underlying device without\nholding the rtnl_mutex, which races with concurrent changes to the\nunderlying device.\n\nAdd a dev-\u003echange_rx_flags hook that is invoked when any of the flags\nthat affect rx filtering change (under the rtnl_mutex), which allows\ndrivers to perform synchronization immediately and only synchronize\nthe address lists in set_multicast_list/set_rx_mode.\n\nSigned-off-by: Patrick McHardy \u003ckaber@trash.net\u003e\nSigned-off-by: David S.

It is implemented as a dmaengine client that smooths over\nthe details of different hardware offload engine implementations. Code\nthat is written to the api can optimize for asynchronous operation and the\napi will fit the chain of operations to the available offload resources. \n \n\tI imagine that any piece of ADMA hardware would register with the\n\t\u0027async_*\u0027 subsystem, and a call to async_X would be routed as\n\tappropriate, or be run in-line. - Neil Brown\n\nasync_tx exploits the capabilities of struct dma_async_tx_descriptor to\nprovide an api of the following general format:\n\nstruct dma_async_tx_descriptor *\nasync_\u003coperation\u003e(..., struct dma_async_tx_descriptor *depend_tx,\n\t\t\tdma_async_tx_callback cb_fn, void *cb_param)\n{\n\tstruct dma_chan *chan \u003d async_tx_find_channel(depend_tx, \u003coperation\u003e);\n\tstruct dma_device *device \u003d chan ? chan-\u003edevice : NULL;\n\tint int_en \u003d cb_fn ? 1 : 0;\n\tstruct dma_async_tx_descriptor *tx \u003d device ?\n\t\tdevice-\u003edevice_prep_dma_\u003coperation\u003e(chan, len, int_en) : NULL;\n\n\tif (tx) { /* run \u003coperation\u003e asynchronously */\n\t\t...\n\t\ttx-\u003etx_set_dest(addr, tx, index);\n\t\t...\n\t\ttx-\u003etx_set_src(addr, tx, index);\n\t\t...\n\t\tasync_tx_submit(chan, tx, flags, depend_tx, cb_fn, cb_param);\n\t} else { /* run \u003coperation\u003e synchronously */\n\t\t...\n\t\t\u003coperation\u003e\n\t\t...\n\t\tasync_tx_sync_epilog(flags, depend_tx, cb_fn, cb_param);\n\t}\n\n\treturn tx;\n}\n\nasync_tx_find_channel() returns a capable channel from its pool. The\nchannel pool is organized as a per-cpu array of channel pointers. The\nasync_tx_rebalance() routine is tasked with managing these arrays. In the\nuniprocessor case async_tx_rebalance() tries to spread responsibility\nevenly over channels of similar capabilities. For example if there are two\ncopy+xor channels, one will handle copy operations and the other will\nhandle xor. In the SMP case async_tx_rebalance() attempts to spread the\noperations evenly over the cpus, e.g. cpu0 gets copy channel0 and xor\nchannel0 while cpu1 gets copy channel 1 and xor channel 1. When a\ndependency is specified async_tx_find_channel defaults to keeping the\noperation on the same channel. A xor-\u003ecopy-\u003exor chain will stay on one\nchannel if it supports both operation types, otherwise the transaction will\ntransition between a copy and a xor resource.\n\nCurrently the raid5 implementation in the MD raid456 driver has been\nconverted to the async_tx api. A driver for the offload engines on the\nIntel Xscale series of I/O processors, iop-adma, is provided in a later\ncommit. With the iop-adma driver and async_tx, raid456 is able to offload\ncopy, xor, and xor-zero-sum operations to hardware engines.\n \nOn iop342 tiobench showed higher throughput for sequential writes (20 - 30%\nimprovement) and sequential reads to a degraded array (40 - 55%\nimprovement). For the other cases performance was roughly equal, +/- a few\npercentage points. On a x86-smp platform the performance of the async_tx\nimplementation (in synchronous mode) was also +/- a few percentage points\nof the original implementation. According to \u0027top\u0027 on iop342 CPU\nutilization drops from ~50% to ~15% during a \u0027resync\u0027 while the speed\naccording to /proc/mdstat doubles from ~25 MB/s to ~50 MB/s.\n \nThe tiobench command line used for testing was: tiobench --size 2048\n--block 4096 --block 131072 --dir /mnt/raid --numruns 5\n* iop342 had 1GB of memory available\n\nDetails:\n* if CONFIG_DMA_ENGINE\u003dn the asynchronous path is compiled away by making\n async_tx_find_channel a static inline routine that always returns NULL\n* when a callback is specified for a given transaction an interrupt will\n fire at operation completion time and the callback will occur in a\n tasklet. if the the channel does not support interrupts then a live\n polling wait will be performed\n* the api is written as a dmaengine client that requests all available\n channels\n* In support of dependencies the api implicitly schedules channel-switch\n interrupts. The interrupt triggers the cleanup tasklet which causes\n pending operations to be scheduled on the next channel\n* Xor engines treat an xor destination address differently than a software\n xor routine.
