iproute2 prior v5.8.0 contained snapshot date:
$ ip -V
ip utility, iproute2-ss190107
But since version v5.7.0-77-gb687d1067169 (released in v5.8.0) there is
new scheme. For releases it contains kernel version:
$ip -V
ip utility, iproute2-5.8.0
and for snapshots build from git it contains version generated with git
describe:
$ip -V
ip utility, iproute2-v5.10.0-74-g2953235e
Thus the original parsing in tst_check_iproute() leads to error:
[: too many arguments
Because function was used only on single place, move expected version
into the function and consider new format as always valid.

Hi,
there are more tests which need ip version check: mc_cmds.sh,
netns_netlink.c, netns_helper.sh.
netns_netlink.c can be checked for tuntap support with simple running
'ip tuntap' [1], mc_cmds.sh correctly detect new version with new
scheme, thus only netns_helper.sh needs to be fixed, although it's just
a warning.
Proper way would be to have C implementation to check version, which
would be reusable in both C and shell. I plan to add it after the
release but because there is git freeze due new release sending just
this quick fix.
Kind regards,
Petr

So if I'm reading this right, this is 2010 again. I wonder if we can
just remove this check as well.
I guess that the most safe variant at the moment would be pushing this
patch, then dropping the check completely after the release.

Thanks for your input. FYI it's about iproute2 v3.0.0 (2011).

I'm ok if we don't want to bother with this (and with patch for
netns_netlink.c [1]). But if you're ok to fix it for the release,
I'd send new patch which fixes it similar way as the fix for netns_netlink.c:
here just run "ip netns" to detect required support instead of checking version
info.
Kind regards,
Petr

I do not have a strong opinion here. If you want to spend time fix these
tests for this release I'm fine with that as long as the fix is minimal
and works fine.
