Therefore in your examples above you will never see '?' and instead you will
see address object names, starting with '_', such as vnic0/_a, vnic0/_b, et
al. So the example above has to be corrected.
Actually no.
this is deep into implementation details,
but since ipmgmtd is calling
libipadm, and we don't want to recurse back into libipadm for name-space
verification (this is done early on, before any doors are set up so
that no other application can invoke ipmgmtd), whether an addrobj name
is provided or not is an implementation choice. We could either
1. have ipmgmtd provide an addrobj name, in which case it would have to
make function calls to set up the addrobj names
2. not provide any name at all.
In either case the library has to be modified to not recurse back into
libipadm, which is ok, since this particular configuration method
is guaranteed to have no ipadm name-space collision.
I've chosen #2 but we could revisit #1 when code review comes around.
I don't think this impacts ARC review though.
ipadm(1M) is going to be new ifconfig(1M) and should be used to manage addresses
and IP interfaces, going forward. To manage addresses using ipadm(1M), they need
to have clearly defined names (either user provided or daemon generated), if not
one cannot perform
* disable-addr
* enable-addr
* set-addrprop
* reset-addrprop
* show-addrprop
* delete-addr
With the choice made, the address added in the exclusive-ip zone cannot be
managed at all. How do you propose to manage that address? Therefore I think
it's not an implementation detail but is related to architecture.
Further, the daemon is the one that manages namespace and generates unique
names. The library libipadm is just a vehicle to retrieve the name. Since you
will be creating addresses from within ipmgmtd, you can directly access those
API's and create a name.
