For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time. Existing drivers can be converted\nto do the same when the maintainer knows for certain that no user code\nrelies on calling seek on the device file.\n\nThe generated code is often incorrectly indented and right now contains\ncomments that clarify for each added line why a specific variant was\nchosen. In the version that gets submitted upstream, the comments will\nbe gone and I will manually fix the indentation, because there does not\nseem to be a way to do that using coccinelle.\n\nSome amount of new code is currently sitting in linux-next that should get\nthe same modifications, which I will do at the end of the merge window.\n\nMany thanks to Julia Lawall for helping me learn to write a

This is done through routing\ntable configuration. For instance, to configure a host to respond\nto any address in 10.1/16 received on eth0 as a local address we can do:\n\nip rule add from all iif eth0 lookup 200\nip route add local 10.1/16 dev lo proto kernel scope host src 127.0.0.1 table 200\n\nThis host is now reachable by any 10.1/16 address (route lookup on\ninput for packets received on eth0 can find the route). On output, the\nrule will not be matched so that this host can still send packets to\n10.1/16 (not sent on loopback). Presumably, external routing can be\nconfigured to make sense out of this.\n\nTo make this work, we needed to modify the logic in finding the\ninterface which is assigned a given source address for output\n(dev_ip_find). We perform a normal fib_lookup instead of just a\nlookup on the local table, and in the lookup we ignore the input\ninterface for matching.\n\nThis patch is useful to implement IP-anycast for subnets of virtual\naddresses.\n\nSigned-off-by: Tom Herbert \u003ctherbert@google.com\u003e\nSigned-off-by: David S.
