Pull request overview
Note
Copilot was unable to run its full agentic suite in this review.
This PR expands EVPN/VXLAN and MUX test robustness, introduces Static Anycast Gateway (SAG) validation, and wires additional EVPN MH (DF/SHL/backup NHG) plumbing across orchagent, cfgmgr, and sync daemons.
Changes:
- Added SAG functional tests and SAG handling across IntfMgr/IntfsOrch, including link-local route programming tied to SAG MAC.
- Improved test stability by replacing fixed sleeps with state-based waits and adding ASIC state drain fixtures.
- Added EVPN MH / split-horizon / backup NHG support across fpmsyncd, portsorch, route/VRF orchestration, and mock/unit-test infrastructure.

Comments suppressed due to low confidence (4)
run-gtest-suite.py:1
import resourceis now unconditional at module import time, which will raise ImportError on platforms without the POSIXresourcemodule (the comment explicitly mentions Windows). To keep the script portable, remove the unconditional import and keep the guardedtry/except ImportErrorimport (or import inside the try block only), then gate the RLIMIT_NOFILE logic on whether the import succeeded.
orchagent/portsorch.cpp:1- This change introduces a call to
FdbOrch::flushAllFDBEntries(...). In this PR diff set, only the declaration is added (inorchagent/fdborch.h), but there is no corresponding implementation shown (e.g., inorchagent/fdborch.cpp). If the implementation is missing, this will fail to link. Add/verify the concrete implementation and ensure it correctly flushes both dynamic and static entries for the given bridge port.
orchagent/request_parser.cpp:1 - The logic that follows this condition is described (in the nearby comment) as assembling removed items into an IPv6 address. After extending the condition to
REQ_T_STRING, that comment is no longer accurate. Update the comment to reflect that the code is now also used to re-join arbitrary string key components that may include ':' (not just IPv6 parsing).
orchagent/vxlanorch.h:1 - The newly added APIs (and a couple of existing ones) take
std::stringby value, which causes unnecessary copies on hot paths and is inconsistent with other APIs in this area. Preferconst std::string& remote_vtep(and similarly fordip) unless ownership transfer is intended.
- teammgr: pass 0 (flags bitmask) to rtnl_link_change() instead of ifindex. The 4th arg is netlink flags, not the interface index; the target link is already identified by orig_link. - fdborch.h, fdbsyncd/fdbsync.h: convert unscoped enum NEXT_HOP_VALUE_TYPE to scoped 'enum class FdbDest : uint8_t' to avoid global namespace pollution and enforce explicit qualification at call sites. - fpmsyncd/routesync: guard ~RouteSync() against null m_nl_sock and free m_link_cache (previously leaked).

Init order changed: EvpnMhOrch constructed before FdbOrch and inserted between gPortsOrch and gBufferOrch in m_orchList; L2NhgOrch appended at end; gShlOrch appended after VXLAN orchs; IntfsOrch ctor signature changed to add APP_SAG_TABLE_NAME. Please verify warm-boot replay order and that ES/DF state is available before FdbOrch/PortsOrch consume it.
There was a problem hiding this comment.
Code is provided to subdue this concern by constructing EVPN-MH before FDB processing and placing it immediately after PortsOrch in the warm-restart list, so ES/DF state is available before FdbOrch consumes FDB work. L2 NHG remains in the orch list and the SAG table is added at the same IntfsOrch priority as INTF_TABLE.
// Create EvpnMhOrch early so its ES/DF state is available when PortsOrch
// processes bridge ports and VLAN members (fixes warm boot ordering)

FDB state machine changes: storeFdbEntryState() on MAC-move now explicitly m_entries.erase(entry) before re-insert; remote_ip replaced by dest_type/dest_value (IFNAME). clearFdbEntry() signature changed to (entry, fdbData); per-port FDB counter decrement is now conditional on getPortByBridgePortId() (previously unconditional). handleSyncdFlushNotif() has three hunks changing bv_id/bridge_port_id resolution during flush. Please double-check counter-decrement parity in every pre-existing path and that flush behavior is unchanged for non-EVPN FDB.
There was a problem hiding this comment.
Code is provided to keep the legacy FDB paths idempotent while allowing the EVPN-MH destination metadata. The branch trace confirms the existing non-EVPN flush path still requires the same bv_id and bridge_port_id match before clearing, and the removal path keeps counter updates tied to resolved bridge ports instead of touching unknown ports.

Neighbor add/remove altered for ES/DF: addNeighbor() integrates ES/DF check (3 hunks) and may now refuse to program a neighbor that previously would have been programmed; removeNeighbor() gains a disable bool parameter (all call sites updated); both getNeighborEntry(NextHopKey) and getNeighborEntry(IpAddress) modified. Please check legacy callers' expectations when a neighbor is 'disabled but not removed' and that isHwConfigured() is cleared correctly.
There was a problem hiding this comment.
Code is provided to keep the disabled-neighbor state explicit instead of deleting the cache entry. The disable path returns early for neighbors that are already absent from hardware, and removeNeighbor(..., true) clears hw_configured while preserving the cache entry for later re-enable.

MUX neighbor update touched by EVPN-MH: set_route() adds an extra branch; MuxNbrHandler::update() and MuxPrefixBasedNbrHandler::update() now factor EVPN-MH into SAI next-hop / tunnel_id during active/standby transitions. Please confirm standby→active and prefix-route fast-path are bit-identical when no ES is configured.
There was a problem hiding this comment.
Code is provided to keep the non-EVPN MUX fast path explicit. The set-route fallback only creates a route when the prefix-route path sees SAI_STATUS_ITEM_NOT_FOUND; otherwise the existing set failure handling is unchanged. Delete handling removes only tracked prefix routes, or preserves the prior standby cleanup path.

Netlink decode rewritten: getEvpnNextHop() rewritten; new rtattr parsers added; onMsg() decode path gains branches for L3 VNI / EVPN-MH attributes. Please verify non-EVPN route decoding is bit-for-bit identical to previous master.
There was a problem hiding this comment.
Code is provided to keep legacy route decoding separate from the EVPN/LWT encap additions. The existing RTA_GATEWAY path still determines IPv4/IPv6 from payload size; the new RTA_VIA branch is only used when the gateway attribute is absent. Encapsulation parsing returns false if VNI, interface, or RMAC is missing.

There was a problem hiding this comment.
Code is provided to keep interface re-apply idempotent. SAG logic only runs when the static_anycast_gateway field is present; otherwise the legacy default mac_addr tuple is still pushed. SAG enable/disable reuses replace/delete FDB operations so repeated application lands in the same state.

Code is provided to keep legacy LAG bring-up sequencing intact. The existing create/admin/MTU/learn-mode/TPID flow still runs first, and the new system MAC update is conditional on system_mac being present.

Why change the signature here? As much as possible, could you limit the changes?
There was a problem hiding this comment.
This parameterization is needed for SAG (Static Anycast Gateway): the SAG VLAN interface paths in intfsorch.cpp now call getLinkLocalEui64Addr(m_sagMac) so the link-local EUI64 is derived from the SAG MAC instead of the global switch MAC. The existing callers in routeorch.cpp and vrforch.cpp still pass gMacAddress, so the non-SAG path is unchanged — the only delta is adding the mac parameter.

This was unintended churn — it changed the log message to use a local neighbor_mac instead of m_syncdNeighbors[neighborEntry].mac. I have reverted it, so this line now matches master.

- Add static_cast<int>(...) at remaining FdbDest %d log sites in fdborch.cpp and qualify FdbDest:: in mock_tests/fdborch/* and mock_tests/fdbsyncd/* (required after enum class conversion). - Restore orchagent/p4orch/tests/mock_routeorch.h (lost during rebase) and update its RouteOrch ctor declaration to match the current prototype (adds NeighOrch* and ZmqServer*).

The teardown in test_InbandIntf called self.wait_for_table_empty('INTF_TABLE')
which did not exist on the class, leaving only the VRF-specific
wait_for_vrf_table_empty. All four parametrizations (Ethernet4, Vlan100,
PortChannel5, Loopback1) raised AttributeError in the finally block:
AttributeError: 'TestInbandInterface' object has no attribute
'wait_for_table_empty'
Add a generic wait_for_table_empty(table_name) that polls the application
DB until the named table is empty, mirroring the existing
wait_for_vrf_table_empty pattern.

Remove the pytest/vstest file changes from this PR while preserving branch history. The C++ and mock test changes remain in the PR; this commit only restores Python test files under tests/ back to master to avoid vstest flakiness. Signed-off-by: Tamer Ahmed <tamerahmed@microsoft.com>

Branch tracing showed two common paths could still mutate state when EVPN-MH was not configured: fdbsyncd accepted L2 nexthop-group netlink events without EVPN NVO, and neighsyncd treated NUD_NOARP without NTF_EXT_LEARNED as a remote-move delete without checking EVPN NVO. Gate both behaviors on EVPN NVO configuration so the feature-inactive path remains idempotent with master. fdbsyncd now ignores L2 NHG messages until NVO exists and clears L2 NHG APP_DB/cache state when NVO is removed. neighsyncd now preserves the existing NOARP ignore behavior unless NVO exists. The new SAG/VXLAN cached state is also default-initialized, and the EVPN split-horizon snprintf format is made type-safe. Add fdbsyncd coverage for the inactive L2 NHG path and make EVPN L2 NHG tests explicitly opt in to NVO before expecting feature-specific APP_DB writes. Validation: focused cppcheck on touched files found no new inactive-path issue. Standard Trixie swss package build passed with PASS 770, PASS 863, PASS 70 and FAIL/ERROR 0.

The integration (pytest) tests under tests/ are restored to their upstream baseline so this PR contains no Python test changes. EVPN-MH test coverage is provided by the C++ mock_tests (gtest) instead. A prior partial revert left ~9.6k lines of unrelated pytest deletions and edits (gearbox.py, macsec.py, test_mux_prefixroute.py, test_p4rt_l3_multicast.py, test_vnet.py, conftest.py, p4rt/*, etc.). All tests/*.py and tests/**/*.py files now match the merge-base. Signed-off-by: Tamer Ahmed <tamerahmed@microsoft.com>

…ghorch churn Gate all EVPN-MH neighsync behavior behind m_isEvpnNvoExist so that the common (feature-disabled) code path is byte-for-byte unchanged from master. Revert the net-new muxorch dualtor route changes that were absent in the pre-rebase baseline; they belong to a separate test-fix effort and are orthogonal to EVPN-MH. Revert unintended cosmetic churn in neighorch. Signed-off-by: Tamer Ahmed <tamerahmed@microsoft.com>

Why I did it
This is part 2/2 of splitting the original EVPN-MH PR (#4262) into reviewable pieces.
Part 1 (#4608) landed the standalone EVPN-MH code (new orchs and headers added without touching existing files).
This PR integrates EVPN-MH with the existing modules (NeighOrch, FdbOrch, VxlanOrch, RouteOrch, MuxOrch, p4orch, fpmsyncd, etc.) and adds the mock/VS tests that exercise both the standalone and integration paths.
The test-infra prerequisites required to land these tests were merged separately as #4599.
How I did it
test_sag.py, EVPN FDB/L3 VXLAN updates) and a few small stabilization tweaks needed for the new tests.How to verify it
makethe swss debs and run mock_tests;test_sag.pyand the new EVPN-MH cases undertests/mock_tests/{neighorch,vxlanorch}_ut.cppshould pass.Which release branch to backport (provide reason below if selected)
Description for the changelog
[EVPN-MH] Integrate EVPN-MH with existing modules and add unit/VS tests.
