@RussellSenior Any update on this? |
|
The problem is here: I tried replacing SOCK_RAW with SOCK_DGRAM but same error. From reading the man page, it would appear that NETLINK_SOCK_DIAG is the issue. No idea what to replace with though. |
|
Found the issue. It's a kernel problem. You need to add CONFIG_NETLINK_DIAG=y to your kernel config. On desktop distros, this is a module loaded dynamically. |
|
@neheb Nice! So I guess the Q now is if OpenWrt should enable that as a kernel default? |
|
Unlikely. That's partially what the debloat patch you linked to does. Maybe create a kernel module package and have ss depend on that. |
|
@neheb Perhaps @RussellSenior should see this thread then. |
|
@neheb Correct me if I'm wrong, but isn't that just a config option for the module named |
|
Dunno. If you install that, does ss work properly? |
|
Ah there's also a kmod-nfnetlink-queue. That one must be it. |
|
@neheb I already had that installed and that does not resolve it. Did you try to re-compile the module with |
|
On further inspection, I don't think that module is the answer. I think a new one has to be specified. Or run a custom kernel with CONFIG_NETLINK_DIAG=y |
|
So it's not a module? I did re-compile the kernel with that option. |
|
Well, the object is netlink_diag.o , which can be built as a module. I was referring to kmod-nfnetlink-queue. That one is unrelated. |
|
Hmm, |
|
There's no kmod-* package for it. One has to be specified and built. Maybe in package/kernel/linux/modules/netfilter.mk This patch as mentioned above makes it work: Anyway, I will close this. As you mentioned, this must go in https://bugs.openwrt.org/ . |
|
fwiw, gmail buried my notifications on this. sorry for the awol. |
|
@neheb Thanks, so reompile with that enabled in the config and then reinstall the kernel? |
|
Maybe something like this would work. I have no idea: |

@neheb Shouldn't this issue be kept open? |
|
I think this was fixed after 19.07. master should work. |
@russelsenior
@jow- unsure if this should be opened on bugs.openwrt.org since it's part of iproute2?
The ss package reports

[strykar@i-5 ~/github/openwrt]$ grep CONFIG_NETLINK_DIAG .configin my buildroot does not show it and the strace log looks like it's indeed the same issue.Strace shows
