When all members are removed from a multicast group, the (true, true) transition path cleaned up replication table entries but skipped process_membership_changes, leaving stale ports in the ASIC groups. Subsequent re-adds failed with "already contains port" (500).

This fix calls process_membership_changes before cleanup_empty_group_replication so mc_port_remove runs on every port. Extend the IPv6 empty-then-add integration test to cover the full add -> remove all -> re-add cycle.

[multicast] Adapt multicast code to new dendrite DPD API
1125c15
This includes a few changes I was already working on in relation to
#9898. This comes after testing with
a feature-gated (for multicast) dpd binary. There's a minor follow-up (oxidecomputer/dendrite#232) that I'll work in after this. - Use actual group tags from DPD responses instead of hardcoded "nexus"
- Rename IntoUnderlayMulticastIpv6 -> IntoUnderlayMulticast (shorter), fits trait definition / more accurate
- Pass MulticastTag as parameter to dpd_update_external_or_create
- Use existing_tag.try_into() / current_tag.try_into() for tag usage
- Nit: dpd_state_matches_tag to use as_str() comparison
- Fix: IpSrc::Subnet -> IpSrc::Any (new dendrite API)
- Fix: SwitchLocation import (moved to sled_agent_types)
- Remove unused multicast type imports

[multicast] Bump dendrite to zl/fix-mcast-empty-transition and remove…
cbc3a5d
… recovery path
This matches Dendrite PR oxidecomputer/dendrite#232.
This update dendrite rev to 5a4f56e (oxidecomputer/dendrite#232), which fixes
the empty-transition in `modify_group_internal`. With the fix, the
delete+recreate recovery path in `modify_group_membership` is no longer
needed. Errors now propagate directly and the reconciler handles
drift on the next pass.

[multicast] Adapt multicast code to new dendrite DPD API
1125c15
This includes a few changes I was already working on in relation to
#9898. This comes after testing with
a feature-gated (for multicast) dpd binary. There's a minor follow-up (oxidecomputer/dendrite#232) that I'll work in after this. - Use actual group tags from DPD responses instead of hardcoded "nexus"
- Rename IntoUnderlayMulticastIpv6 -> IntoUnderlayMulticast (shorter), fits trait definition / more accurate
- Pass MulticastTag as parameter to dpd_update_external_or_create
- Use existing_tag.try_into() / current_tag.try_into() for tag usage
- Nit: dpd_state_matches_tag to use as_str() comparison
- Fix: IpSrc::Subnet -> IpSrc::Any (new dendrite API)
- Fix: SwitchLocation import (moved to sled_agent_types)
- Remove unused multicast type imports

[multicast] Bump dendrite to zl/fix-mcast-empty-transition and remove…
cbc3a5d
… recovery path
This matches Dendrite PR oxidecomputer/dendrite#232.
This update dendrite rev to 5a4f56e (oxidecomputer/dendrite#232), which fixes
the empty-transition in `modify_group_internal`. With the fix, the
delete+recreate recovery path in `modify_group_membership` is no longer
needed. Errors now propagate directly and the reconciler handles
drift on the next pass.

When all members are removed from a multicast group, the (true, true) transition path cleaned up replication table entries but skipped process_membership_changes, leaving stale ports in the ASIC groups. Subsequent re-adds failed with "already contains port" (500).
This fix calls process_membership_changes before cleanup_empty_group_replication so mc_port_remove runs on every port. Extend the IPv6 empty-then-add integration test to cover the full add -> remove all -> re-add cycle.

When all members are removed from a multicast group, the (true, true) transition path cleaned up replication table entries but skipped process_membership_changes, leaving stale ports in the ASIC groups. Subsequent re-adds failed with "already contains port" (500).

[multicast] Bump dendrite to zl/fix-mcast-empty-transition and remove…
cbc3a5d
… recovery path
This matches Dendrite PR oxidecomputer/dendrite#232.
This update dendrite rev to 5a4f56e (oxidecomputer/dendrite#232), which fixes
the empty-transition in `modify_group_internal`. With the fix, the
delete+recreate recovery path in `modify_group_membership` is no longer
needed. Errors now propagate directly and the reconciler handles
drift on the next pass.

When all members are removed from a multicast group, the (true, true) transition path cleaned up replication table entries but skipped process_membership_changes, leaving stale ports in the ASIC groups. Subsequent re-adds failed with "already contains port" (500).
This fix calls process_membership_changes before cleanup_empty_group_replication so mc_port_remove runs on every port. Extend the IPv6 empty-then-add integration test to cover the full add -> remove all -> re-add cycle.

[multicast] Adapt multicast code to new dendrite DPD API
1125c15
This includes a few changes I was already working on in relation to
#9898. This comes after testing with
a feature-gated (for multicast) dpd binary. There's a minor follow-up (oxidecomputer/dendrite#232) that I'll work in after this. - Use actual group tags from DPD responses instead of hardcoded "nexus"
- Rename IntoUnderlayMulticastIpv6 -> IntoUnderlayMulticast (shorter), fits trait definition / more accurate
- Pass MulticastTag as parameter to dpd_update_external_or_create
- Use existing_tag.try_into() / current_tag.try_into() for tag usage
- Nit: dpd_state_matches_tag to use as_str() comparison
- Fix: IpSrc::Subnet -> IpSrc::Any (new dendrite API)
- Fix: SwitchLocation import (moved to sled_agent_types)
- Remove unused multicast type imports
