packet: add PACKET_RESERVE sockopt

2008-07-19T01:05:19Z

Add new sockopt to reserve some headroom in the mmaped ring frames in front of the packet payload. This can be used f.i. when the VLAN header needs to be (re)constructed to avoid moving the entire payload. Signed-off-by: Patrick McHardy Signed-off-by: David S. Miller

packet: deliver VLAN TCI to userspace

2008-07-15T05:50:39Z

Store the VLAN tag in the auxillary data/tpacket2_hdr so userspace can properly deal with hardware VLAN tagging/stripping. Signed-off-by: Patrick McHardy Signed-off-by: David S. Miller

packet: support extensible, 64 bit clean mmaped ring structure

2008-07-15T05:50:15Z

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.

[AF_PACKET]: Add option to return orig_dev to userspace.

2007-04-26T05:29:14Z

Add a packet socket option to allow the orig_dev index to be returned to userspace when passing traffic through a decapsulated device, such as the bonding driver. This is very useful for layer 2 traffic being able to report which physical device actually received the traffic, instead of having the encapsulating device hide that information. The new option is called PACKET_ORIGDEV. Signed-off-by: Peter P. Waskiewicz Jr. Signed-off-by: David S. Miller

[PACKET]: Add optional checksum computation for recvmsg

2007-02-08T20:38:46Z

This patch is needed to make ISC's DHCP server (and probably other DHCP servers/clients using AF_PACKET) to be able to serve another client on the same Xen host. The problem is that packets between different domains on the same Xen host only have partial checksums. Unfortunately this piece of information is not passed along in AF_PACKET unless you're using the mmap interface. Since dhcpd doesn't support packet-mmap, UDP packets from the same host come out with apparently bogus checksums. This patch adds a mechanism for AF_PACKET recvmsg(2) to return the status along with the packet. It does so by adding a new cmsg that contains this information along with some other relevant data such as the original packet length. I didn't include the time stamp information since there is already a cmsg for that. This patch also changes the mmap code to set the CSUMNOTREADY flag on all packets instead of just outoing packets on cooked sockets. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[AF_PACKET]: annotate

2006-12-03T05:21:24Z

Weirdness: the third argument of socket() is net-endian here. Oh, well - it's documented in packet(7). Signed-off-by: Al Viro Signed-off-by: David S. Miller

v2.4.3.2 -> v2.4.3.3

2002-02-05T02:11:38Z

- Hui-Fen Hsu: sis900 driver update - NIIBE Yutaka: Super-H update - Alan Cox: more resyncs (ARM down, but more to go) - David Miller: network zerocopy, Sparc sync, qlogic,FC fix, etc. - David Miller/me: get rid of various drivers hacks to do mmap alignment behind the back of the VM layer. Create a real protocol for it.
