2023-11-07Take into account CRC field for framingHEADmasterFrediano Ziglio1-2/+2
Signed-off-by: Frediano Ziglio <freddy77@gmail.com>
2023-11-07Avoid possible bug with strict aliasingFrediano Ziglio1-4/+11
Tell code we are breaking strict aliasing. Most of the time works but with some strong optimisation compiler could produce not working code because of the aliasing breakage. Signed-off-by: Frediano Ziglio <freddy77@gmail.com>
2023-11-07Remove useless assert in codeFrediano Ziglio1-2/+0
Always true, it would be better to write a test instead. Signed-off-by: Frediano Ziglio <freddy77@gmail.com>

2016-10-11Bump release version to 1.1Frediano Ziglio1-1/+1
Signed-off-by: Frediano Ziglio <fziglio@redhat.com>
2016-10-11Use ppoll and different threadingFrediano Ziglio1-174/+120
Instead of using a thread for reading from tun(s)/remote use a thread for every direction. This remove a lot of synchronisation from the code. Some test I did prove that this implementation although using a single thread for a direction is faster allowing to use higher speed. Also this make easier to reduce the internal queue at a minimum emulating better a real card and allowing to do some tests with QoS settings. Signed-off-by: Frediano Ziglio <fziglio@redhat.com>
2016-10-11Make test work even for remote caseFrediano Ziglio5-24/+186
Use network namespaces to test the remote case using a single machine. Server is run in a subprocess with a different namespace. Client and server are connected with a veth interface. Signed-off-by: Frediano Ziglio <fziglio@redhat.com>
2016-10-11Avoid bytes_from_first_read to be set again to 0 while transferingFrediano Ziglio1-1/+1

Signed-off-by: Frediano Ziglio <fziglio@redhat.com>
2016-10-09Use 2 tun devices for local caseFrediano Ziglio6-30/+129
This is required to better handle 2 network queue (back and forth) improving network emulation. In real case there are 2 queue, one on local machine and another in the remote one. This will also allow to reduce the queue. Another problem is that using a single queue there was a single flow and the combined bandwidth (forth and back) was limited using a single flow. Now two flows are correctly used for the local case. This require some more complicate NAT fixing the checksums. Signed-off-by: Frediano Ziglio <fziglio@redhat.com>

2016-07-28change completely client/server protocolFrediano Ziglio4-33/+209
Allows to specify options only on one end making easier to change them. Also one UDP port is automatically assigned.
2016-07-28initial client/server implementationFrediano Ziglio3-4/+86
Allows to restrict latency/bandwidth between 2 machines. This require to setup both machines pointing to each other. Works but it's hard to change parameters. To do that both end encapsulate packets in a UDP packet (the UDP data it's just the packet received from tun interface). Quite easy but works. Would be easier if server will be launched just with a port specification while client with all parameters so to make easier to change.
