Summary:
- During network stress testing, ASSERT happened in gs2200m_ioctl_connect()
- The test was nxplayer (http audio streaming) and repeating wget every 0.5sec
- gs2200m_ioctl_connect() calls gs2200m_send_cmd() to send an AT command
- Then it waits for a synchronous command response.
- However, if heavy tcp traffic happens on another socket, it can receive a bulk packet
- With this commit, if it receives such a packet then the packet is duplicated.
- After that, the duplicated packet is added to the packet queue and notify the userland.
Impact:
- Affect almost all use cases with gs2200m
Testing:
- Tested with both spresense:wifi and spresense:wifi_smp
- Tested with nxplayer (http audio streaming) and repeat wget
