Dear Maintainer,
* What led up to the situation?
I was experimenting with ip address as a replacement for ifconfig
and discovered something which surprised me.
# ip address flush dev eth0 primary label eth0:foo
will delete all the addresses under label eth0:foo not just the
primary one.
* What outcome did you expect instead?
as the man pages describes ip address flush as using the same
parameters as ip address show. I expected it to delete only the first
address under that label.
eg:
root@crackle:~# ## make 5 addresses
root@crackle:~#
root@crackle:~# ip address add local 10.11.22.31/8 label eth0:foo dev eth0
root@crackle:~# ip address add local 10.11.22.32/8 label eth0:foo dev eth0
root@crackle:~# ip address add local 10.11.22.33/8 label eth0:foo dev eth0
root@crackle:~# ip address add local 10.11.22.34/8 label eth0:foo dev eth0
root@crackle:~# ip address add local 10.11.22.35/8 label eth0:foo dev eth0
root@crackle:~#
root@crackle:~# ## list them
root@crackle:~#
root@crackle:~# ip address show dev eth0 label eth0:foo
inet 10.11.22.31/8 scope global eth0:foo
inet 10.11.22.32/8 scope global secondary eth0:foo
inet 10.11.22.33/8 scope global secondary eth0:foo
inet 10.11.22.34/8 scope global secondary eth0:foo
inet 10.11.22.35/8 scope global secondary eth0:foo
root@crackle:~#
root@crackle:~# ## use the primary flag:
root@crackle:~#
root@crackle:~# ip address show dev eth0 primary label eth0:foo
inet 10.11.22.31/8 scope global eth0:foo
root@crackle:~#
root@crackle:~# ## only listsed 10.11.22.31
root@crackle:~# ## but this will delete them all
root@crackle:~#
root@crackle:~# ip address flush dev eth0 primary label eth0:foo
root@crackle:~#
root@crackle:~# ## list them again:
root@crackle:~#
root@crackle:~# ip address show dev eth0 label eth0:foo
root@crackle:~#
root@crackle:~# ## they're all gone. :(
"secondary" works as expected, just not "primary".
I can guess why this might be, but the manual should probably
warn about it.
