FS#3221 - ubox: validate.c: Link-Local IPv6 with interface ID not supported
validate.c uses inet_pton for identifying IPv6 addresses [1], and this seems to not understand interface identifiers as used for Link-local IPv6 addresses.
Reproduce:
root@FFF-GW-Adrian:~# /sbin/validate_data host fdff::1 host - fdff::1 = true root@FFF-GW-Adrian:~# /sbin/validate_data host fe80::1 host - fe80::1 = true root@FFF-GW-Adrian:~# /sbin/validate_data host fe80::1%br-mesh host - fe80::1%br-mesh = false
This is a problem practically whenever validata_data is used to check uci values.
For example, it is not possible to use a link-local address for specifying an NTP server:
https://github.com/openwrt/openwrt/blob/master/package/utils/busybox/files/sysntpd#L33
If ‘server:list(host)’ is changed to ‘server:list(string)’ there, it obviously works fine, as it’s just the validation.
