From e3af0032b236dc52d4a74c4d740e57a1f6d520aa Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Sat, 7 Nov 2009 18:55:16 +0100 Subject: set the close-on-exec flag on all file descriptors Added the "fd_util" library, which attempts to use the new thread-safe Linux system calls pipe2(), accept4() and the options O_CLOEXEC, SOCK_CLOEXEC. Without these, it falls back to FD_CLOEXEC, which is not thread safe. This is particularly important for the "pipe" output plugin (and others, such as JACK/PulseAudio), because we were heavily leaking file descriptors to child processes. --- src/mixer/oss_mixer_plugin.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/mixer') diff --git a/src/mixer/oss_mixer_plugin.c b/src/mixer/oss_mixer_plugin.c index 4e169bbc..028786ae 100644 --- a/src/mixer/oss_mixer_plugin.c +++ b/src/mixer/oss_mixer_plugin.c @@ -19,6 +19,7 @@ #include "mixer_api.h" #include "output_api.h" +#include "fd_util.h" #include @@ -122,7 +123,7 @@ oss_mixer_open(struct mixer *data, GError **error_r) { struct oss_mixer *om = (struct oss_mixer *) data; - om->device_fd = open(om->device, O_RDONLY); + om->device_fd = open_cloexec(om->device, O_RDONLY); if (om->device_fd < 0) { g_set_error(error_r, oss_mixer_quark(), errno, "failed to open %s: %s", -- cgit v1.2.3
