From 329b24da3b394bb8f504266861a38b8e547c1f6a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zolt=C3=A1n=20Papp?= Date: Tue, 8 Sep 2026 21:05:33 +0200 Subject: [PATCH] [client] Drop the unused file drop port from the signal exchange The field dates from the first file drop commit, when the sender was to advertise the port its receiver had bound. Pinning the tunnel-side port replaced that: the port is fixed, a receiver that cannot bind it redirects the well-known port to whatever it got, and the sender dials the constant without negotiating. Nothing ever read the field. It never reached main, so field number 12 goes back to being free rather than needing a reserved slot. Regenerated with the pinned protoc 3.21.12 and protoc-gen-go 1.26.0, so the diff is the field and the descriptor bytes behind it. --- shared/signal/proto/signalexchange.pb.go | 80 ++++++++++-------------- shared/signal/proto/signalexchange.proto | 4 -- 2 files changed, 34 insertions(+), 50 deletions(-) diff --git a/shared/signal/proto/signalexchange.pb.go b/shared/signal/proto/signalexchange.pb.go index 6be79f1d2..8e07977f0 100644 --- a/shared/signal/proto/signalexchange.pb.go +++ b/shared/signal/proto/signalexchange.pb.go @@ -239,9 +239,6 @@ type Body struct { // fallback dial target when DNS resolution of relayServerAddress fails. // SNI/TLS verification still uses relayServerAddress.
