We have an issue where the kernel stops processing packets for a certain amount of time (in our case upwards of 15+ seconds) before it continues again. This is on Debian 9 (Stretch).
After exhaustive debugging in our native applications, we determined that the issue was likely with the kernel or NIC drivers.
We upgraded to Debian 11 (Bullseye) and the issue resolved itself.
I see the following statement about Debian 9
Debian 9.13 (18 July 2020; 22 months ago) this is the final update for codename Stretch.
Is there a way for me to see how many CVEs/NIC Driver Bugs/Kernel firmware bugs were resolved from 18 July 2020 until now?
Trying to get an idea of how much velocity there has been and code changes, such that we can conclusively say the issue was with the kernel firmware/NIC driver.
