  Packet, where are you? -- eBPF-based Linux kernel networking debugger

  

if you have a recent enough kernel, this change https://github.com/cilium/pwru/pull/148 means that it will print the reason the packet was dropped in the output - see https://lwn.net/Articles/885729/

There's a whole heap of reasons a packet can be dropped:

• linux

  980 170,074 10.0 C

  Linux kernel source tree

https://github.com/torvalds/linux/blob/76f598ba7d8e2bfb4855b...

In any case, this makes it less painful than going back to read the kernel source. I don't think that the gif in the README is up to date with this change - it's 2 years old and this feature only appeared 2 months ago.
