From 7b4bf06ba7f31ea8069fc8927729d70ab98b9b64 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Tue, 15 Feb 2011 00:40:17 +0100 Subject: [PATCH] socket: refuse socket activation for SysV services Make sure that when a .socket unit is installed without its matching .service we don't end up activating a legacy SysV/LSB service with the same name. SysV/LSB style services do not support passing sockets and we don't want to extend SysV/LSB to ensure we don't break compatibility with other systems. --- src/socket.c | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-) diff --git a/src/socket.c b/src/socket.c index e386c7f2..3f57e353 100644 --- a/src/socket.c +++ b/src/socket.c @@ -169,6 +169,13 @@ static int socket_instantiate_service(Socket *s) { if (r < 0) return r; +#ifdef HAVE_SYSV_COMPAT + if (SERVICE(u)->sysv_path) { + log_error("Using SysV services for socket activation is not supported.
