[#6380] Disconnect fails when interface traffic exceeds 2 GiB

Summary:
Disconnect fails when interface traffic exceeds 2 GiB |
| Detailed description |
Once the interface has exceeded 2^31 bytes, the shell arithmetic in autodisconnect_runner_network can't keep up.
The line:
if [[ "$packets_after" -lt "$((packets_before+g_dontcountbytes))" ]]; then
wraps around, as an example (in ash), do:
bytes=2200000000; [[ "$bytes" -lt $((bytes + 2048)) ]] && echo "disconnect"
Attached is the patch I'm using (for v0.4.7) to work around this. It's a bit messy but I don't know any easy way to
do 64-bit arithmetic in a 32-bit shell (without invoking python!) |
