Gunar Schorcht 35676ca712 cpu/esp_common: fix of blocking mechanism in FreeRTOS queus ... When FreeRTOS semaphores, as required by ESP-IDF, are used together with `gnrc_netif`, RIOT may crash if `STATUS_RECEIVE_BLOCKED` is used as a blocking mechanism in the FreeRTOS adaptation layer. The reason for this is that `gnrc_netif` uses thread flags since PR #16748. If the `gnrc_netif` thread is blocked because of a FreeRTOS semaphore, and is thus in `STATUS_RECEIVE_BLOCKED` state, the `_msg_send` function will cause a crash because it then assumes that `target->wait_data` contains a pointer to a message of type `msg_t`, but by using thread flags it contains the flag mask. This situation can happen if the ESP hardware is used while another thread is sending something timer controlled to the `gnrc_netif` thread. To solve this problem `STATUS_MUTEX_LOCKED` is used instead of `STATUS_RECEIVE_BLOCKED` and `STATUS_SEND_BLOCKED`		2022-08-24 09:05:25 +02:00
