Hey @jokob-sk
It's time to move to Alpine 3.21 :D

There's an issue with netifaces, it's abandoned project amd fork netifaces-plus is having the same issue compiling.

      netifaces.c:1808:9: error: initialization of 'int' from 'void *' makes integer from pointer without a cast [-Wint-conversion]
       1808 |         NULL,
            |         ^~~~
      netifaces.c:1808:9: note: (near initialization for 'msghdr.__pad1')
      netifaces.c:1843:33: warning: comparison of integer expressions of different signedness: '__u32' {aka 'unsigned int'} and 'int' [-Wsign-compare]
       1843 |         if (pmsg->hdr.nlmsg_seq != seq || pmsg->hdr.nlmsg_pid != sanl.nl_pid)
            |                                 ^~
      error: command '/usr/bin/gcc' failed with exit code 1
      [end of output]

But luckily there's netifaces2 that should work fine.

@jokob-sk would you be able to test with Alpine 3.21 and netifaces2?

Am I willing to test this? 🧪

• I will do my best to test this feature on the netlertx-dev image when requested within 48h and report bugs to help deliver a great user experience for everyone and not to break existing installations.

Can I help implement this? 👩‍💻👨‍💻

• Yes
• No

Thanks for keeping my base image updated :)

Just pushed to dev - should be ready in 15 min. - would be great if you could click around (looks good to me though). netifaces was only use din the omada plugin, but the import was commented out, so removed it completely.
