From: Guillaume Lucas <guillaumex.lucas(a)intel.com&gt; Using kernel mux, a recursive locking is detected. This issue is due to the fact that the DLC_AUX is not closed by ofono. This is not done because the shutdown_device() function in charge of it is called in the context of an AT callback function and for an AT sent in this same dlc. Calling the real shutdown_device() function using a timer solved the issue. --- plugins/ifx.c | 14 +++++++++++++- 1 files changed, 13 insertions(+), 1 deletions(-) diff --git a/plugins/ifx.c b/plugins/ifx.c index 9c2a5c1..3581f80 100644 --- a/plugins/ifx.c +++ b/plugins/ifx.c @@ -93,6 +93,7 @@ struct ifx_data { guint dlc_poll_count; guint dlc_poll_source; guint dlc_init_source; + guint shutdown_source; guint mux_init_timeout; guint frame_size; int mux_ldisc; @@ -190,8 +191,9 @@ static void xsim_notify(GAtResult *result, gpointer user_data) } } -static void shutdown_device(struct ifx_data *data) +static gboolean shutdown_device_cb(gpointer user_data) { + struct ifx_data *data = user_data; int i, fd; DBG(""); @@ -224,8 +226,18 @@ static void shutdown_device(struct ifx_data *data) done: g_io_channel_unref(data->device); data->device = NULL; + data->shutdown_source = 0; + return FALSE; +} + +static void shutdown_device(struct ifx_data *data) +{ + DBG(""); + data->shutdown_source = g_timeout_add_seconds(0, + shutdown_device_cb, data); } + static void dlc_disconnect(gpointer user_data) { struct ofono_modem *modem = user_data; -- 1.6.3.3 --------------------------------------------------------------------- Intel Corporation SAS (French simplified joint stock company) Registered headquarters: "Les Montalets"- 2, rue de Paris, 92196 Meudon Cedex, France Registration Number: 302 456 199 R.C.S.
