Checker / reload:
- Reload's update-in-place branch now mirrors b.Address onto the
runtime health.Backend. Without this, GetBackend kept returning
the pre-reload address indefinitely after a config edit that
touched addresses but not healthcheck settings — the VPP sync
path reads cfg.Backends directly so the dataplane moved on
while the gRPC and SPA view stayed wedged on the old IPv4/IPv6.
Sync (internal/vpp/lbsync.go):
- reconcileVIP now detects encap mismatch in addition to
src-ip-sticky mismatch and takes the full tear-down / re-add
path via a new shared recreateVIP helper. Triggered when every
backend flips address family (gre4 <-> gre6) and the existing
VIP can no longer accept new ASes — previously the sync wedged
with 'Invalid address family' until a full maglevd restart.
- setASWeight is issued whenever the state machine requests
flush (a.Flush=true), not only on the weight-value transition
edge. Fixes the case where a backend reached StateDisabled
after its effective weight had already been drained to 0 by
pool failover — the sticky-cache entries pointing at it were
previously never cleared.
maglev-frontend:
- signal.Ignore(SIGHUP) so a controlling-terminal disconnect
doesn't kill the daemon.
- debian/vpp-maglev.service grants CAP_SYS_ADMIN in addition to
CAP_NET_RAW so setns(CLONE_NEWNET) can join the healthcheck
netns. Comment documents the 'operation not permitted' symptom
and notes the knob can be dropped if the deployment doesn't use
the 'netns:' healthcheck option.
LB plugin counters (internal/vpp/lbstats.go + friends):
- Fix the VIP counter regex: the LB plugin registers
vlib_simple_counter_main_t names without a leading '/'
(vlib_validate_simple_counter in counter.c:50 uses cm->name
verbatim; only entries that set cm->stat_segment_name get a
slash). first/next/untracked/no-server now read through as
live values instead of zero.
- Drop the per-backend FIB counter block end-to-end (proto,
grpcapi, metrics, vpp.Client, lbstats, maglevc). Traced from
lb/node.c:558 into ip{4,6}_forward.h:141 — the LB plugin
forwards by writing adj_index[VLIB_TX] directly and bypassing
ip{4,6}_lookup_inline, which is the only path that increments
lbm_to_counters. The backend's FIB load_balance stats_index
literally never ticks for LB-forwarded traffic, so the column
was always zero and misleading. docs/implementation/TODO
records the full investigation and the recommended upstream
path (new lb_as_stats_dump API message) for when we're ready
to carry that VPP patch.
- maglevc show vpp lb counters: plain-text tabular headers.
label() wraps strings in ANSI escapes (~11 bytes of overhead),
but tabwriter counts bytes, not rendered width — so a header
row with label()'d cells and data rows with plain cells drifts
column alignment on every row. color.go comment now spells
out the constraint: label() only works when column N is
wrapped identically in every row (key-value layouts are fine,
multi-column tables with header-only labelling are not).
SPA:
- stores/scope.ts is cookie-backed (maglev_scope, 1 year,
SameSite=Lax). App.tsx hydrates from the cookie then validates
against the fetched snapshots: a cookie referencing a maglevd
that no longer exists falls through to snaps[0] instead of
leaving the user on a ghost selection.
- components/Flash.tsx wraps props.value in createMemo. Solid's
on() fires its callback on every dep notification, not on
value change — source is right in solid-js/dist/solid.js:460,
no equality check. Without the memo, flipping scope between
two 'connected' maglevds (or any other cross-store reactive
re-eval that doesn't actually change the concrete string)
replays the animation every time. createMemo's default ===
dedupe fixes it in one place for every Flash consumer,
superseding the local createMemo workaround we'd added in
BackendRow earlier.
