From 27b4923ba00f0a7511c7ebf5f19313d6313052e9 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sat, 31 Aug 2013 15:44:58 -0400 Subject: make realpath use O_PATH when opening the file this avoids failure if the file is not readable and avoids odd behavior for device nodes, etc. on old kernels that lack O_PATH, the old behavior (O_RDONLY) will naturally happen as the fallback. --- src/misc/realpath.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/misc') diff --git a/src/misc/realpath.c b/src/misc/realpath.c index d238ed01..2b846497 100644 --- a/src/misc/realpath.c +++ b/src/misc/realpath.c @@ -21,7 +21,7 @@ char *realpath(const char *restrict filename, char *restrict resolved) return 0; } - fd = open(filename, O_RDONLY|O_NONBLOCK|O_CLOEXEC); + fd = open(filename, O_PATH|O_NONBLOCK|O_CLOEXEC); if (fd < 0) return 0; __procfdname(buf, fd); -- cgit v1.2.1
