[LLC]: multicast receive device match

2006-08-14T01:56:26Z

Fix from Aji_Srinivas@emc.com, STP packets are incorrectly received on all LLC datagram sockets, whichever interface they are bound to. The llc_sap datagram receive logic sends packets with a unicast destination MAC to one socket bound to that SAP and MAC, and multicast packets to all sockets bound to that SAP. STP packets are multicast, and we do need to know on which interface they were received. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[LLX]: SOCK_DGRAM interface fixes

2006-08-05T05:59:50Z

The datagram interface of LLC is broken in a couple of ways. These were discovered when trying to use it to build an out-of-kernel version of STP. First it didn't pass the source address of the received packet in recvfrom(). It needs to copy the source address of received LLC packets into the socket control block. At the same time fix a security issue because there was uninitialized data leakage. Every recvfrom call was just copying out old data. Second, LLC should not merge multiple packets in one receive call on datagram sockets. LLC should preserve packet boundaries on SOCK_DGRAM. This fix goes against the old historical comments about UNIX98 semantics but without this fix SOCK_DGRAM is broken and useless. So either ANK's interpretation was incorect or UNIX98 standard was wrong. Signed-off-by: Stephen Hemminger Acked-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[LLC]: add multicast support for datagrams

2006-06-18T04:26:08Z

Allow mulitcast reception of datagrams (similar to UDP). All sockets bound to the same SAP receive a clone. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[LLC]: allow applications to get copy of kernel datagrams

2006-06-18T04:26:06Z

It is legal for an application to bind to a SAP that is also being used by the kernel. This happens if the bridge module binds to the STP SAP, and the user wants to have a daemon for STP as well. It is possible to have kernel doing STP on one bridge, but let application do RSTP on another bridge. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[LLC]: use rcu_dereference on receive handler

2006-06-18T04:26:04Z

The receive hander pointer might be modified during network changes of protocol. So use rcu_dereference (only matters on alpha). Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[LLC]: allow datagram recvmsg

2006-06-18T04:26:02Z

LLC receive is broken for SOCK_DGRAM. If an application does recv() on a datagram socket and there is no data present, don't return "not connected". Instead, just do normal datagram semantics. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[LLC]: use more efficient ether address routines
