From a839ee75d85c4f1d3183b8955c62d54f6a8dec88 Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Fri, 11 Nov 2016 10:54:54 -0500 Subject: basic/virt: fix userns check on CONFIG_USER_NS=n kernel (#4651) ENOENT should be treated as "false", but because of the broken errno check it was treated as an error. So ConditionVirtualization=user-namespaces probably returned the correct answer, but only by accident. Fixes #4608. --- src/basic/virt.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src') diff --git a/src/basic/virt.c b/src/basic/virt.c index 69b0f96183..d8d57381ad 100644 --- a/src/basic/virt.c +++ b/src/basic/virt.c @@ -496,7 +496,7 @@ static int userns_has_mapping(const char *name) { f = fopen(name, "re"); if (!f) { log_debug_errno(errno, "Failed to open %s: %m", name); - return errno == -ENOENT ? false : -errno; + return errno == ENOENT ? false : -errno; } n = getline(&buf, &n_allocated, f); -- cgit v1.2.3-54-g00ecf
