From 875622c39e925f866587629b997e47fe4c7ff1cd Mon Sep 17 00:00:00 2001 From: Giuseppe Scrivano Date: Mon, 5 Nov 2018 23:06:14 +0100 Subject: [PATCH] core, sysctl: skip ENOENT for /proc/sys/net/unix/max_dgram_qlen sysctl is disabled for /proc mounted from an user namespace thus entries like /proc/sys/net/unix/max_dgram_qlen do not exist. In this case, skip the error and do not try to change the default for the AF_UNIX datagram queue length. --- src/core/main.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/core/main.c b/src/core/main.c index 807f5457c2..1fd3f10f7e 100644 --- a/src/core/main.c +++ b/src/core/main.c @@ -1391,7 +1391,7 @@ static int bump_unix_max_dgram_qlen(void) { r = read_one_line_file("/proc/sys/net/unix/max_dgram_qlen", &qlen); if (r < 0) - return log_warning_errno(r, "Failed to read AF_UNIX datagram queue length, ignoring: %m"); + return log_full_errno(r == -ENOENT ?
