[PATCH v12] passt, pasta: Introduce unified multi-address data structures

23 Oct 2026

As preparation for supporting multiple addresses per interface,
we replace the single addr/prefix_len fields with an array. The
array consists of a new struct inany_addr_entry containing an
address and prefix length, both in inany_addr format.

Despite some code refactoring, there are only two real functional
changes:
- The indicated IPv6 prefix length is now properly stored, instead
  of being ignored and overridden with the hardcoded value 64, as
  has been the case until now.
- Since even IPv4 addresses now are stored in IPv6 format, we
  also store the corresponding prefix length in that format,
  i.e. using the range [96,128] instead of [0,32].

In conf_ip6(), the explicit IN6_IS_ADDR_UNSPECIFIED() check on the
address at the end of the function is no longer needed: for
host-discovered addresses, it is now checked inside the if (!a) block
before calling fwd_set_addr(); for user-provided addresses (via -a),
validation already rejects unspecified addresses at parse time.

---
v2: -Using inany_addr instead of protocol specific addresses as
     entry address field.

v3: -Merging into one array, directly in struct ctx
    -Changed prefix_len and flags fields in struct inany_addr_entry
     to uint8_t, since that makes the struct directly migratable

v4: -Updated according to changes in previous commits
    -Updated according to feedback from David G.
    -Squashed IP4_MASK macro commit into this one

v6: -Renamed and moved some definitions
    -Introduced fwd_set_addr() and fwd_get_addr() already in this commit
    -Eliminated first_v4/v6() functions, replaced with fwd_get_addr()
    -Some other changes as suggested by David G.
    -I kept the flag CONF_ADDR_LINKLOCAL, since it will be
     needed later in an address selection function.

v7: -Introduced CONF_ADDR_GENERATED flag
    -Other fixes based on feedback from David and Stefano.
    -I changed signature of inany_prefix_len(), but I did not change
     its semantics, since the premise of David's comment is wrong: the
     caller does *not* explicitly know he is dealing with an IPv4 address.
     In fact, there are examples later in this series where it may be an
     IPv6 address, and the caller just trusts he gets the return value in
     the appropriate format.
    -Intoduced the inverse of inany_prefix_len(), called inany_prefix_len6()
     which always returns the prefix in IPv6 or mapped IPv4 format.
     The name of the function isn't great, but any alternative I came up
     with became too long to be practical.

v8: -Added inany_prefix_v4() (David G.) to extract IPv4 address and
     prefix length simultaneously, replacing inany_prefix_len().
    -Removed both inany_prefix_len() and inany_prefix_len6()
     auto-detecting functions. Prefix length attached to an inany is
     now always stored in IPv6 format (96-128 for IPv4-mapped).
    -fwd_set_addr() now requires prefix_len in IPv6 format; callers
     updated to pass prefix_len + 96 for IPv4 addresses.
    -Fixed -n option to store prefix_len in IPv6 format.
    -Fixed addr_seen regression: when address was set via -a,
     addr_seen was not initialised in conf_ip4().
    -Replaced assert() with graceful no-op in dhcp.c and ndp.c when
     no address is configured (David G.).
    -Note: addr_seen is still initialised both at conf_ip*() time
     and at DHCP/DHCPv6 send time (David's concern). This
     inconsistency will be addressed in a follow-up.
    -Introduced a new CONF_ADDR_ANY macro to be used for address
     selection, as suggested by Stefano.
    -Deferred introduction of an explicit scope field (replacing
     CONF_ADDR_LINKLOCAL flag) to a later commit or series.

v9: -Rebased on changes made by David Gibson.
    -Some minor changes based on feedback from David.
    -Defined a new macro CONF_ADDR_GLOBAL to supplant CONF_ADDR_ANY.
    -I did not follow up David's suggestion to introduce three
     functions to replace the current fwd_get_addr(), because I
     don't think it would solve any problems. The 'flags' field
     encode both provenance and type properties orthogonally, and
     callers need different combinations of them. That is the very
     point of that field, and I see nothing confusing in it.
     It is correct that some of the calls to fwd_get_addr() go away
     in later commits, but enough of them remain to justify its
     existence. Defining three new functions to replace it would only
     make them wrappers around fwd_get_addr(), and serve no purpose in
     my view.

v10: -Redefined and refactored function fwd_get_addr().

v11: -Changes after feedback from Stefano.
      - Fixed coverity false positives.
      - Fixed bug introduced by wrongly handling ipv4 link local
        addresses analogously to ipv6 ditto. These addresses should in
        practice be handled like global IPv4 address. Removed now
        redundant inany_is_linklocal() function and let fwd_get_addr()
        only use inany_is_linklocal6().
      - In the same function the removal of the fallback does not
        imply a functional change:
        * -a without a prefix still gets the class-based default from
          inany_default_prefix_len()
        * host-discovered addresses get their prefix_len from netlink.
      - The changes in conf_print() is not unrelated: inet_ntop() may
        fail and leave a stale buffer.
      - Re-introduced CONF_ADDR_ANY, this time to 0
      - Kept next_addr_idx_(). There is a working solution without it,
        but (kernel) checkpatch complains about it.
        solution for this.
      - Some other minor changes

v12:  - Re-defined CONF_ADDR_ANY to be a bitmap
      - Added assert() in fwd_set_addr() to ensure no address is added
        without at least one flag.
