Bug 818022 – net-misc/iputils-20210722-r1: stabilisation (was: ping tries to use ipv6 when ipv6 disabled)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Daniel Frey 2021-10-13 22:14:16 UTC]

I'm not sure when this regression happened, but using ping on a host that has no ipv6 kernel support and with "-ipv6" set in USE throws an error:

$ ping dns
ping: socket: Address family not supported by protocol

It's trying to create an ipv6 socket when the system doesn't support it.


Reproducible: Always

Steps to Reproduce:
1. Install latest stable net-misc/iputils
2. Ping a host on machine with no ipv6 support
Actual Results:  
It throws error/warning:

ping: socket: Address family not supported by protocol

Expected Results:  
It should ping with no warnings or errors

Upstream noticed a regression:

https://github.com/iputils/iputils/pull/370

Some applications using ping will have problems if ping throws unintended errors and they will not behave normally (or not work at all.)

Forgot to show package USE:

$ emerge -pv iputils

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] net-misc/iputils-20210722::gentoo  USE="arping filecaps nls ssl -caps -clockdiff -doc -gcrypt -idn -ipv6 -nettle -rarpd -rdisc -static -test -tftpd -tracepath -traceroute6" 0 KiB

USE="-ipv6" is set system-wide on machine in question.
