No such device (os error 19)

[jlopezr]

Hi!

I am having problems with bandwhich compiled by myself.

sudo ./bandwhich
Error:

 lo: No such device (os error 19)
 ens3: No such device (os error 19)
 docker0: No such device (os error 19)
 br-a352cf46e04d: No such device (os error 19)
 veth1792dd0: No such device (os error 19)
 veth84d80b4: No such device (os error 19)

On the other hand, the binary version available on github is working perfectly. The same error happens in Linux x64 and Linux armv7 that I crosscompiled.

Same issue here upon installing with cargo.

On Manjaro 5.15

Same issue here, also installed with cargo on Ubuntu 22.04LTS.

I've run into this while fixing the build on Void Linux. The old binary from our repos still works just fine, the new one doesn't. The only things that changed between then:

• Rust was updated a few times, going from 1.46.0 to 1.68.2
• I updated the socket2 library, because it wouldn't build on Rust 1.64+ otherwise

I've got https://pastebin.com/A8bJuafj and https://pastebin.com/aKLfRb9Z, which are strace logs from both of the binaries. The first one is the broken one, the second is the older, working binary.

The critical bit seems to be the setsockopt syscall, which is the one that fails, that is being called with slightly different parameters now:

diff --git a/old b/new

I haven't gotten any further yet, but maybe this motivates someone else to take a deeper look here :)

Sounds like https://github.com/rust-lang/rust/pull/78802 to me

[jcgruenhage]

That's the build issue resolved by updating socket2, but apparently there's more libraries in bandwhich's dependency tree that relied on this behaviour: mio relied on that behaviour prior to version 0.7.6 as well. mio is in the dependency tree twice, once in version 0.6.21, brought in by tokio@0.2.2, and once in version 0.7.0 brought in by crossterm. I think the big task here is migrating tokio to the stable release, bringing up mio as well. Whether that's actually related though, I'm not sure. No such device sounds like a different problem to me.

[jcgruenhage]

I'll be opening a PR later with the dependencies upgraded, but I can already report some success: With pnet ugpraded, it works again.

same on ubuntu 23.04

[stappersg]

After doing

git remote add jcgruenhage https://github.com/jcgruenhage/bandwhich
git fetch jcgruenhage
git checkout upgrades-2023-04-11

I was able to do

cargo build

succesfully.

I have try downgrade rust version to 1.62.1 and rebuild, bandwhich run succesfully.

[jwbowen]

Is this project still active?

[cyqsimon]

This should be fixed in #273. See also #275.
