2008-07-15SUNRPC: Support registering IPv6 interfaces with local rpcbind daemonChuck Lever1-0/+3
Introduce a new API to register RPC services on IPv6 interfaces to allow the NFS server and lockd to advertise on IPv6 networks. Unlike rpcb_register(), the new rpcb_v4_register() function uses rpcbind protocol version 4 to contact the local rpcbind daemon. The version 4 SET/UNSET procedures allow services to register address families besides AF_INET, register at specific network interfaces, and register transport protocols besides UDP and TCP. All of this functionality is exposed via the new rpcb_v4_register() kernel API. A user-space rpcbind daemon implementation that supports version 4 of the rpcbind protocol is required in order to make use of this new API. Note that rpcbind version 3 is sufficient to support the new rpcbind facilities listed above, but most extant implementations use version 4.

2008-07-15mmc: change .get_ro() callback semanticsAnton Vorontsov1-0/+12
Now get_ro() callback must return 0/1 values for its logical states, and negative errno values in case of error. If particular host instance doesn't support RO/WP switch, it should return -ENOSYS. This patch changes some hosts in two ways: 1. Now functions should be smart to not return negative values in "RO asserted" case (particularly gpio_ calls could return negative values for the outermost GPIOs). Also, board code usually passes get_ro() callbacks that directly return gpioreg & bit result, so at91_mci, imxmmc, pxamci and mmc_spi's get_ro() handlers need take special care when returning platform's values to the mmc core. 2. In case of host instance didn't implement get_ro() callback, it should really return -ENOSYS and let the mmc core decide what to do about it (mmc core thinks the same way as the hosts, so it isn't functional change).

2008-07-15mmc: add support for card-detection pollingAnton Vorontsov1-0/+11

We want to poll the card and see if there was a change. 1 second poll interval seems resonable.

2008-07-14packet: support extensible, 64 bit clean mmaped ring structurePatrick McHardy1-0/+21
The tpacket_hdr is not 64 bit clean due to use of an unsigned long and can't be extended because the following struct sockaddr_ll needs to be at a fixed offset. Add support for a version 2 tpacket protocol that removes these limitations. Userspace can query the header size through a new getsockopt option and change the protocol version through a setsockopt option. The changes needed to switch to the new protocol version are: 1. replace struct tpacket_hdr by struct tpacket2_hdr 2. query header len and save 3. set protocol version to 2 - set up ring as usual 4. for getting the sockaddr_ll, use (void *)hdr + TPACKET_ALIGN(hdrlen) instead of (void *)hdr + TPACKET_ALIGN(sizeof(struct tpacket_hdr)) Steps 2 and 4 can be omitted if the struct sockaddr_ll isn't needed.

2008-07-14vlan: deliver packets received with VLAN acceleration to network tapsPatrick McHardy1-0/+1
When VLAN header stripping is used, packets currently bypass packet sockets (and other network taps) completely.

2008-07-14tun: Fix/rewrite packet filtering logicMax Krasnyansky1-3/+21
Please see the following thread to get some context on this http://marc.info/?l=linux-netdev&m=121564433018903&w=2 Basically the issue is that current multi-cast filtering stuff in the TUN/TAP driver is seriously broken. Original patch went in without proper review and ACK. It was broken and confusing to start with and subsequent patches broke it completely. To give you an idea of what's broken here are some of the issues: - Very confusing comments throughout the code that imply that the character device is a network interface in its own right, and that packets are passed between the two nics. Which is completely wrong. - Wrong set of ioctls is used for setting up filters. They look like shortcuts for manipulating state of the tun/tap network interface but in reality manipulate the state of the TX filter. - ioctls that were originally used for setting address of the the TX filter got "fixed" and now set the address of the network interface itself. Which made filter totaly useless. - Filtering is done too late. Instead of filtering early on, to avoid unnecessary wakeups, filtering is done in the read() call. The list goes on and on :) So the patch cleans all that up. It introduces simple and clean interface for setting up TX filters (TUNSETTXFILTER + tun_filter spec) and does filtering before enqueuing the packets. TX filtering is useful in the scenarios where TAP is part of a bridge, in which case it gets all broadcast, multicast and potentially other packets when the bridge is learning. So for example Ethernet tunnelling app may want to setup TX filters to avoid tunnelling multicast traffic. QEMU and other hypervisors can push RX filtering that is currently done in the guest into the host context therefore saving wakeups and unnecessary data transfer.
