Bug report

What is the problem?

On ramips targets (observed on D-Link DIR860L), the sysfs paths of the WLAN interfaces changed from OpenWrt 19.07 to 21.02:

Before:

pci0000:00/0000:00:00.0/0000:01:00.0
pci0000:00/0000:00:01.0/0000:02:00.0

After:

1e140000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0
1e140000.pcie/pci0000:00/0000:00:01.0/0000:02:00.0

/etc/config/wireless is currently not covered by #2372, so some config scripts fail after the upgrade.

Possible solutions:

  • Regenerate /etc/config/wireless on reconfig
    • Requires to move more user intent to /etc/config/gluon
    • Might lead to unstable radio index assignments on some devices?
      • Regenerate only when the old config is obviously broken?
      • Ignore radio indices for intent configuration, instead use more generic "config for all 2.4GHz", "config for all 5GHz"?
  • Target-specific migration script
