[PATCH v2 0/4] Bluetooth: Improve retrying of connection attempts

Posted by Jonas Dreßler 1 year, 11 months ago

Since commit 4c67bc74f016 ("[Bluetooth] Support concurrent connect
requests"), the kernel supports trying to connect again in case the
bluetooth card is busy and fails to connect.

The logic that should handle this became a bit spotty over time, and also
cards these days appear to fail with more errors than just "Command
Disallowed".

This series refactores the handling of concurrent connection requests
by serializing all "Create Connection" commands for ACL connections
similar to how we do it for LE connections.

v1: https://lore.kernel.org/linux-bluetooth/20240102185933.64179-1-verdre@v0yd.nl/
v2:
  - Move to using hci_sync queue for "Create Connection" and therefore
    always serialize those requests.
  - Follow commit message style better and properly cite patches

Jonas Dreßler (4):
  Bluetooth: Remove superfluous call to hci_conn_check_pending()
  Bluetooth: hci_event: Use HCI error defines instead of magic values
  Bluetooth: hci_conn: Only do ACL connections sequentially
  Bluetooth: Remove pending ACL connection attempts
