bluetoothd segfault

Hello Bluetooth experts,

I wrote a program that scan the air for obex capable devices, but I frequently get a segmentation fault from bluetoothd. The attached file contains the execution log of bluetoothd using valgrind. Any help will be appreciated.

I found at least one possible cause of this, if you are connecting to multiple devices simultaneously (have multiple ative sdp sessions) src/glib-helper.c:find_by_bdaddr is broken because it will return 0 (found matching) for all sessions where the adapter matches which can leads to remove the wrong context and cause a crash like you are seeing.

In this case you the following patch should fix it:

+ int ret;

- return (bacmp(&ctxt->dst, &search->dst) &&

+ ret = bacmp(&ctxt->src, &search->src);
+ if (ret != 0)

}
