From d9da339bf12f6433eaeb624589956f2f8737a6a0 Mon Sep 17 00:00:00 2001 From: Frantisek Sumsal Date: Fri, 10 Apr 2026 18:32:33 +0200 Subject: [PATCH] sd-varlink: scale down the limit of connections per UID to 128 1024 connections per UID is unnecessarily generous, so let's scale this down a bit. D-Bus defaults to 256 connections per UID, but let's be even more conservative and go with 128. --- src/libsystemd/sd-varlink/sd-varlink.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/libsystemd/sd-varlink/sd-varlink.c b/src/libsystemd/sd-varlink/sd-varlink.c index fdcbcff0e1..372ede755b 100644 --- a/src/libsystemd/sd-varlink/sd-varlink.c +++ b/src/libsystemd/sd-varlink/sd-varlink.c @@ -39,7 +39,7 @@ #include "varlink-org.varlink.service.h" #define VARLINK_DEFAULT_CONNECTIONS_MAX 4096U -#define VARLINK_DEFAULT_CONNECTIONS_PER_UID_MAX 1024U +#define VARLINK_DEFAULT_CONNECTIONS_PER_UID_MAX 128U #define VARLINK_DEFAULT_TIMEOUT_USEC (45U*USEC_PER_SEC) #define VARLINK_COLLECT_MAX 1024U
