Bug 598078 – net-misc/netifrc-0.5.0 - error when using netmask notation

• Product: Gentoo Hosted Projects
• Status: RESOLVED FIXED

[Description asears 2016-10-25 13:29:19 UTC]

When using netmask notation in config_<interface>, an error is received on startup:
Error: inet prefix is expected rather than "10.10.2.178//16"

It would appear that an extra slash is being added. Using CIDR notation works normally.

Reproducible: Always

Steps to Reproduce:
1. Set config_<interface> in /etc/conf.d/net to a static IP using netmask e.g. "192.168.1.1 netmask 255.255.255.0"
2. Restart net.<interface>

Actual Results:  
script calls command
ip addr add 192.168.1.1//24 broadcast + dev <interface>
Error: inet prefix is expected rather than "192.168.1.1//24".

Expected Results:  
script calls command
ip addr add 192.168.1.1/24 broadcast + dev <interface>
(no error)

I have the same bug. Downgrading to 0.4.0-r1 fixes static network for me.

Workaround, worked for me:

config_eth0="192.168.0.2/24"

or

config_eth0="192.168.0.2/24 brd 192.168.0.255"

These options are also correct on Handbook (Interface handlers).

Here's a quickfix before I get 0.5.1 out the door.

net/iproute2.sh:136:
- netmask="/$(_netmask2cidr "$1")"
+ netmask="$(_netmask2cidr "$1")"

However I'd strongly recommend everybody start moving to just CIDR notation.

That broadcast is the default implied value from the specified address, you don't need to specify it.

0.5.1 released with fix.
