This commit removes the lock from the list manipulation code in esp_netif_objects.c, because we already have another lock/task context for lwip. So the list manipulation is unsafe and safety must be assured by the stack layer (in esp_netif_lwip). Problems with current locking: * implementation of locking was wrong -- lazy init style of creating the mutex is not thread safe (and destroying it if we have no interface makes the problem exhibit very frequently) * locking only the list won't solve issues when assessing interfaces atomically * maintaining multiple locks is problematic, as we often switch between lwip context and user context in internal implementation of esp_netif_lwip Closes https://github.com/espressif/esp-idf/issues/12261 |
