I have installed the 4.19 kernel version as instructed on a physical machine. And I need to reinstall the NIC driver. However, I get an error about missing /lib/modules/linux-4.19-xx/build .

Therefore, I would like to ask you whether you installed the linux patch on a virtual machine or a physical machine and whether you have encountered problems that require reinstalling drivers such as the NIC driver.

I have two problems and hope you can give me some advise.

1. Regarding policy collection, generating a simple dataset with parts of CCs (cubic and reno) is okay. However, I encounter a 'connection failed' error when trying to collect data for other CCs (e.g., vegas, bbr).
   

2. As for training, after obtaining the final dataset, I face the issue of memory consumption continuously increasing until the process is killed."
   

I'm interested in the "policy collector", but the link of pantheon-modified repository in "Creating the Dataset/1. Using the Policy Collector" seems to be invalid.

          I am now relatively certain that the issue is related to the code '#include <sys/socket.h>' line28 in the '/usr/src/linux-headers-4.19.112-0062/include/linux/if.h' file, which references a user-space library. This issue seems similar to the one described in this GitHub issue: https://github.com/openzfs/zfs/issues/10601.

In fact, there may be other problems with the kernel module that are preventing the installation of network card drivers and NVIDIA GPU drivers (basically, anything that relies on kernel header files). I would like to know if you can confirm this issue. When using Sage for inference, did you use only the CPU, or were there any GPU-related dependencies?

Hi, Thanks for your excellent work of sage cc algorithm. I'm recently designing my new cc algorithm，but I don’t have a deep understanding of the linux kernel. So i have some problems in Integrating my congestion control algorithms into the kernel. Could you please tell me where to find the the sage's linux kernel code(like the cubic's source code net/ipv4/tcp_cubic.c)?

I found that you use the setsockopt to acquire the network stats(TCP_INFO sock option) as the rl model's input and also use the setsockopt to change the cc window(TCP_CWND sock option), could you please tell me where to find the source code?

Please forgive me for bothering you with such basic programming questions. Thanks very much if you can help me.

With Ubuntu16.04 (Kernel 4.15.0.142), dpkg the .deb and the kernel patch was installed.

But when loading the modified kernel 4.19, the process is stuck in ' load inital ramdisk...' and cannot boot up.

Could you give me some advice and help me to deal with it?

Hi when I try to run the sample script, I get the following error with no output data. Can you provide some guidance on how to resolve the issue? Thanks.

Dear Dr. Abbasloo. Firstly, thank you for this really fantastic work. I was wondering if you have any plan to release the collected pool of policies with 60 million data points. It will greatly advance this research field. Thanks!

Hi thank you for the speedy response. Executing the script without root still leads to no data output.

My error seems to stem from the last line of server.sh. What is the last line supposed to execute? I ran through the setup again to make sure I had the environment configured properly but am still seeing the error. Thanks.

After the installation, something wrong happens when running run_sample.sh. ERROR seems to be: [Cntthread] null alpha.

Could you give me some advice of debugging?
