Public bug reported: The default encoding for GIOChannel is UTF-8, but rfkill event is binary data. If the value is invalid UTF-8, gsd-rfkill-manager will fail to receive rfkill event.
Steps: Run suspend/resume Test (> 127 times) Failure Rate: 100% In some platforms, bt will be re-probed after s3. If bt is re-probed, rfkill-idx will increase. And, 128 is the first invalid UTF-8 $ rfkill list ID TYPE DEVICE SOFT HARD 1 wlan phy0 unblocked unblocked 128 bluetooth hci0 unblocked unblocked Error Message: gnome-settings-daemon/plugins/rfkill/rfkill-glib.c gsd-rfkill[2062]: event_cb: 1 g_io_channel_read_chars gsd-rfkill[2062]: g_io_channel_fill_buffer: cur_len=0, read_size=8 gsd-rfkill[2062]: g_io_channel_read_chars: 5 *bytes_read=8 gsd-rfkill[2062]: event_cb: 1 read=8 gsd-rfkill[2062]: event_cb: 1 source->read_buf->len=0 gsd-rfkill[2062]: event_cb: 1 source->encoded_read_buf->len=0 gsd-rfkill[2062]: RFKILL event: idx 127 type 2 (BLUETOOTH) op 1 (DEL) soft 0 hard 0 gsd-rfkill[2062]: event_cb: 2 g_io_channel_read_chars gsd-rfkill[2062]: event_cb: 2 read=0 gsd-rfkill[2062]: event_cb: 2 source->read_buf->len=8 gsd-rfkill[2062]: event_cb: g_list_length=1 gsd-rfkill[2062]: Removed Bluetooth rfkill with ID 127 gsd-rfkill[2062]: event_cb: 1 g_io_channel_read_chars gsd-rfkill[2062]: event_cb: 1 read=0T gsd-rfkill[2062]: event_cb: 1 source->read_buf->len=16 gsd-rfkill[2062]: event_cb: g_list_length=0 ** Affects: gnome-settings-daemon (Ubuntu) Importance: Undecided Status: New ** Tags: bionic cosmic ** Patch added: "0001-rfkill-set-encoding-as-NULL.patch" https://bugs.launchpad.net/bugs/1797322/+attachment/5199851/+files/0001-rfkill-set-encoding-as-NULL.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1797322 Title: gsd-rfkill-manager fails to receive rfkill event To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1797322/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
