af_packet: Prefixed tpacket_v3 structs to avoid name space collision

2011-08-26T16:38:44Z

structs introduced in tpacket_v3 implementation are prefixed with 'tpacket' to avoid namespace collision. Compile tested. Signed-off-by: Chetan Loke Signed-off-by: David S. Miller

af-packet: Added TPACKET_V3 headers.

2011-08-25T02:40:39Z

Added TPACKET_V3 definitions. Signed-off-by: Chetan Loke Signed-off-by: David S. Miller

packet: Add 'cpu' fanout policy.

2011-07-06T08:56:38Z

Unfortunately we have to use a real modulus here as the multiply trick won't work as effectively with cpu numbers as it does with rxhash values. Signed-off-by: David S. Miller

packet: Add pre-defragmentation support for ipv4 fanouts.

2011-07-06T05:34:52Z

The skb->rxhash cannot be properly computed if the packet is a fragment. To alleviate this, allow the AF_PACKET client to ask for defragmentation to be done at demux time. Signed-off-by: David S. Miller

packet: Add fanout support.

2011-07-06T05:34:52Z

Fanouts allow packet capturing to be demuxed to a set of AF_PACKET sockets. Two fanout policies are implemented: 1) Hashing based upon skb->rxhash 2) Pure round-robin An AF_PACKET socket must be fully bound before it tries to add itself to a fanout. All AF_PACKET sockets trying to join the same fanout must all have the same bind settings. Fanouts are identified (within a network namespace) by a 16-bit ID. The first socket to try to add itself to a fanout with a particular ID, creates that fanout. When the last socket leaves the fanout (which happens only when the socket is closed), that fanout is destroyed. Signed-off-by: David S. Miller

af_packet: prevent information leak

2011-06-07T05:42:06Z

In 2.6.27, commit 393e52e33c6c2 (packet: deliver VLAN TCI to userspace) added a small information leak. Add padding field and make sure its zeroed before copy to user. Signed-off-by: Eric Dumazet CC: Patrick McHardy Signed-off-by: David S. Miller

af-packet: Add flag to distinguish VID 0 from no-vlan.

2011-06-02T04:18:03Z

Currently, user-space cannot determine if a 0 tcp_vlan_tci means there is no VLAN tag or the VLAN ID was zero. Add flag to make this explicit. User-space can check for TP_STATUS_VLAN_VALID || tp_vlan_tci > 0, which will be backwards compatible. Older could would have just checked for tp_vlan_tci, so it will work no worse than before.

packet_mmap: expose hw packet timestamps to network packet capture utilities

2010-06-02T12:53:56Z

This patch adds a setting, PACKET_TIMESTAMP, to specify the packet timestamp source that is exported to capture utilities like tcpdump by packet_mmap. PACKET_TIMESTAMP accepts the same integer bit field as SO_TIMESTAMPING. However, only the SOF_TIMESTAMPING_SYS_HARDWARE and SOF_TIMESTAMPING_RAW_HARDWARE values are currently recognized by PACKET_TIMESTAMP. SOF_TIMESTAMPING_SYS_HARDWARE takes precedence over SOF_TIMESTAMPING_RAW_HARDWARE if both bits are set. If PACKET_TIMESTAMP is not set, a software timestamp generated inside the networking stack is used (the behavior before this setting was added). Signed-off-by: Scott McMillan Signed-off-by: David S. Miller

packet: support for TX time stamps on RAW sockets

2010-04-13T08:30:48Z

Enable the SO_TIMESTAMPING socket infrastructure for raw packet sockets. We introduce PACKET_TX_TIMESTAMP for the control message cmsg_type. Similar support for UDP and CAN sockets was added in commit 51f31cabe3ce5345b51e4a4f82138b38c4d5dc91 Signed-off-by: Richard Cochran Signed-off-by: David S. Miller
