ipcpd: Fix setting MTU for eth-llc

2018-05-08T10:04:58+00:00

The MTU was not correctly set for the eth-llc ipcp. This also fixes a missing definition of ETH_MAX_MTU, which was introduced in kernel v4.10. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Use correct MTU for eth-dix

2018-05-07T15:55:07+00:00

The eth-dix IPCP was using a hardcoded MTU of 1500 bytes, but could support higher MTUs. Now jumbo frames are supported. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix truncate of small packets

2018-04-05T08:33:10+00:00

The truncate was setting the length to the frame length, instead of the actual payload length to be delivered to the N+1. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Add ethertype check

2018-04-05T08:33:05+00:00

An ethertype check was missing for the DIX ethernet IPCP, causing crashes if there is other traffic on the network. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Avoid unnecessary copy in eth writer

2018-04-05T08:32:58+00:00

This writes into the Ethernet device directly from the rdrbuff to avoid a copy on the write side in the Ethernet IPCPs. This does not work for the netmap device. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Avoid unnecessary copy in eth reader

2018-04-05T08:32:55+00:00

This reads from the Ethernet device directly into the rdrbuff to avoid a copy on the read side in the Ethernet IPCPs. This does not work for the netmap device. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Enable locking threads to a CPU core

2018-04-05T08:31:52+00:00

This adds a function that locks a thread to a random core. This greatly improves performance on multi-cpu systems. There is no portable way to do this, this only implements it for GNU/Linux. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix frame buffer in eth ipcps

2018-04-05T08:30:26+00:00

The packets were being sent and read into a buffer that had the payload length instead of the frame length. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Add validity checks for eth-dix

2018-03-12T09:32:17+00:00

This will check if the Ethertype value is a valid Ethertype in the irm tool and the eth-dix IPCPd. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Add length field to eth-dix

2018-03-10T21:14:01+00:00

Some NICs added padding to the Ethernet II frames causing bad frame lengths and GPB unpack fails. This adds a 2-byte length field to the DIX frame to circumvent this. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
