2006-01-06[PATCH] knfsd: fix hash function for IP addresses on 64bit little-endian machines.NeilBrown1-1/+13
The hash.h hash_long function, when used on a 64 bit machine, ignores many of the middle-order bits. (The prime chosen it too bit-sparse). IP addresses for clients of an NFS server are very likely to differ only in the low-order bits. As addresses are stored in network-byte-order, these bits become middle-order bits in a little-endian 64bit 'long', and so do not contribute to the hash. Thus you can have the situation where all clients appear on one hash chain. So, until hash_long is fixed (or maybe forever), us a hash function that works well on IP addresses - xor the bytes together. Thanks to "Iozone" <capps@iozone.org> for identifying this problem.

2006-01-05[NETFILTER]: Call POST_ROUTING hook before fragmentationPatrick McHardy4-83/+16
Call POST_ROUTING hook before fragmentation to get rid of the okfn use in ip_refrag and save the useless fragmentation/defragmentation step when NAT is used. The patch introduces one user-visible change, the POSTROUTING chain in the mangle table gets entire packets, not fragments, which should simplify use of the MARK and CLASSIFY targets for queueing as a nice side-effect.

2006-01-04[PATCH] net: swich device attribute creation to default attrsKay Sievers1-47/+21
Recent udev versions don't longer cover bad sysfs timing with built-in logic. Explicit rules are required to do that. For net devices, the following is needed: ACTION=="add", SUBSYSTEM=="net", WAIT_FOR_SYSFS="address" to handle access to net device properties from an event handler without races. This patch changes the main net attributes to be created by the driver core, which is done _before_ the event is sent out and will not require the stat() loop of the WAIT_FOR_SYSFS key.

2006-01-03[DCCP]: Do not process a packet twice when it's not in state DCCP_OPEN.Andrea Bittau1-22/+34
When packets are received, the connection is either in DCCP_OPEN [fast-path] or it isn't. If it's not [e.g. DCCP_PARTOPEN] upper layers will perform sanity checks and parse options. If it is in DCCP_OPEN, dccp_rcv_established() will do it. It is important not to re-parse options in dccp_rcv_established() when it is not called from the fast-path. Else, fore example, the ack vector will be added twice and the CCID will see the packet twice. The solution is to always enfore sanity checks from the upper layers. When packets arrive in the fast-path, sanity checks will be performed before calling dccp_rcv_established(). Note(acme): I rewrote the patch to achieve the same result but keeping dccp_rcv_established with the previous semantics and having it split into __dccp_rcv_established, that doesn't does do any sanity check, code in state != DCCP_OPEN use this lighter version as they already do the sanity checks.

2006-01-03[DECNET]: Only use local routersPatrick Caulfield1-5/+8
The attached patch makes DECnet routing only use routers from the same area - rather than the highest rated router seen. In theory there should not be an out-of-area router on a local network but some networks are bridged rather than properly routed. VMS seems to behave similarly: if I bring up a VMS node with no router then it can't see anything else on the global network.
