[PATCH v2 0/3] Commonise address any check

[sagi@grimberg.me (Sagi Grimberg)]

Both iscsit and nvmet need to check the listening endpoint
portal is not INADDR_ANY (or IN6ADDR_ANY_INIT) when replying
to a discovery information query (iscsi sendtaragets or nvmet
discovery log pages). If indeed the nvmet port or iscsit portal
are listening on any address, they need to return the source
address of the socket that carried the query itslef.

iscsit already does this while nvmet did not.
instead of copying the inaddr_any check, place it in net-utils
and call it from both (patches 1+3).

In addition, fix the behavior in nvmet (patch 2).

Changes from v1:
- small alignment fix in inet_addr_is_any
- warn if got unexpected address family
- make in6_any static

Sagi Grimberg (3):
  net/utils: Introduce inet_addr_is_any
  nvmet: don't return "any" ip address in discovery log page
  iscsi-target: use common inet_addr_is_any
