Hi all,
jls(8) is generating inconsistent output regarding IPv4 & IPv6 addresses.
Below are some examples documenting the behavior.
- For readability, I use `--libxo json` and pipe the output through jq.
However, the information is the same as without `--libxo`
- These are all jails spawned by ezjail(8), hence spawned using the old rc.conf syntax.
Can anyone reproduce these inconsistencies on their system?
Possibly with the native jail.conf / other jail managers.
Furthermore: I would be willing to try fixing the behavior.
However, do you think changing/correcting the output at this point will
break existing software?
Cheers,
Christian

jls --libxo json
IPv6 addresses are not printed at all
...
{
...
"ipv4": "10.123.234.6",
...
}
...
jls --libxo json -n all
Both address types are printed, but not particularly nicely (should use JSON arrays)
Additionally, the ip(4|6) variables seem inconsistent.
...
{
"ip4": "disable",
"ip6": "disable",
...
"ip4.addr": "10.123.234.6",
"ip4.saddrsel": true,
"ip6.addr": "2001:ffff:ffff::b,2001:ffff:ffff::d",
"ip6.saddrsel": true
}
...
jls --libxo json -v
Attention: no -n specified
Prints IPv6-Addresses as IPv4 addresses.
...
{
...
"ipv4_addrs": [
"10.123.234.6",
"2001:ffff:ffff::b",
"2001:ffff:ffff::d"
]
}
...
