** Description changed: [Impact] - * only impact Bionic machines because series after Bionic already - included this patch. + This patch is for this issue: + steps: + 1. pair bluetooth keyboard + 2. see the dialog asking user input the code for pairing. + 3. press "esc" to cancel it. + 4. blutoothd segfault shows in dmesg after a while. + 5. Bluetooth shows off on setting UI of right top corner. dmesg shows: [ 978.138593] bluetoothd[1569]: segfault at 0 ip 000055564abe0a06 sp 00007ffe4bec6410 error 4 in bluetoothd[55564ab77000+f3000] + [Test Case] 1. pair bluetooth keyboard 2. see the dialog asking user input the code for pairing. 3. press "esc" to cancel it. 4. the bluetooth should still work to pair another bluetooth device. [Regression Potential] - * low, because the same patch from upstream is already there on Groovy, - Focal and Eoan. + * This patch workaround the case that a queue node was created but not + yet assigned function before user input pairing keycode. If the user + cancel the paring before inputting pairing keycode then assign the + function pointer a dummy 'direct_match'. + + * Bluetoothd responses to Bluetooth functions and "queue" is a shared + common data structure, so in case of regression happens then blutoothd + systemd service would be crashed. + + * We can verify this by operating add/remove BT devices to trigger + queue operations. + + * I verified on target machine BIOS ID:0983 on BT mouse, keyboard, + headset on pairing, remove and functionality checking. [Other Info] * NO.
