| | | | | | | | | | | | Add a "packet_burst" config option that will cause clatd to read (and write) in bursts of up to that number of packets, instead of always only reading one packet at a time. This reduces poll overhead and improves performance. The variable is initially set to 10. Bug: 24113287 Change-Id: I7feba4127538c5a89f92e0ebea1fb75971d6b901

* clatd: Fix packet corruption seen with GRO packetsSubash Abhinov Kasiviswanathan2016-05-233-8/+9
| | | | | | | | | | | | | | | | MTU serves a dual purpose for CLAT. The segment size of the packet ring is based on the MAXMTU apart from the interface MTU itself. GRO coalesce happens on the receive path which is not affected by the MTU (transmit). In other words, increasing the MAXMTU does not affect if a GRO coalesced packet is delivered to CLAT. It only affects the amount of data being read from the TPacket ring. Introduce a new parameter MAXMRU which handles the increased MRU to account for GRO packets. Increase the ring size to compensate for the larger segments to maintain the same throughput as earlier. Change-Id: I30057970973b99181505e698f64e7fa5aa0a27d9

| * clatd: Relay checksum information from packet socket to TUN interfaceSubash Abhinov Kasiviswanathan2015-11-156-9/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this change, we can notify network stack to disable checksum validation for GRO packets as well as other packets which have checksum validation completed earlier in a driver. GRO packets have the ip_summed field set to CHECKSUM_PARTIAL while checksum offloaded packets have the ip_summed field as CHECKSUM_UNNECESSARY. Kernel copies this ip_summed field to the status field in the tpacket filter. The information from the status field is then passed as part of the TUN header to the TUN interface. Any other packet will have the complete checksum validation done in the network stack. Note that this only applies to packets which are captured in packet sockets and passed onto the TUN interface.

| * Revert "clatd: Use the TUN_NOCHECKSUM flag for the tun device"Subash Abhinov Kasiviswanathan2015-11-154-77/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 7efed4e30259da5348c4a7c2c77a0d0d4b13834d. This change may bypass checksum validation for all packets even if they have not been validated earlier. Hardware supports checksum offload for IPv4 / IPv6 UDP and TCP packets only. ICMPv4 / ICMPv6 / fragmented packet checksum offload is not supported and as a result the checksum will not be validated even once before these packet are delivered to the application.

* clatd: Use the TUN_NOCHECKSUM flag for the tun deviceSubash Abhinov Kasiviswanathan2015-10-124-0/+77
| | | | | | | | | This is needed to handle cases when the packet socket receives a GRO coalesced packet which will not have a valid TCP checksum. TUN_NOCHECKSUM is used only when the checksum has already been verified prior to this and GRO is being used. Change-Id: I1409967523152bb7620b4881526e78e8c222cc72
