Just like MGMT_OP_START_DISCOVERY, we should reject MGMT_OP_START_SERVICE_DISCOVERY with MGMT_STATUS_BUSY when we are paused for suspend. Signed-off-by: Abhishek Pandit-Subedi <abhishekpandit@chromium.org> --- On ChromeOS, we started getting reports of scanning failing after resuming from suspend. The root cause was that Start Service Discovery was being called while discovery was supposed to be paused for suspend and it was screwing up some internal state. Adding this check immediately fixed it. The fix was tested by doing the following: * Set Discovery Filter ({'transport': 'auto'}) * Start Discovery * Suspend * Resume * Check the Discovering property Without the fix, this test failed when checking the Discovering property above. net/bluetooth/mgmt.c | 8 ++++++++ 1 file changed, 8 insertions(+)
