YAMAMOTO Takashi 09f3a1ec8e tcp_send_buffered: throttle IOB allocations for send Consider a bi-directional TCP connection: 1. we use all IOBs for tx queue 2. we advertize zero recv window because we have no free IOBs 3. if the peer tcp does the same thing, both sides advertize zero window and can not drain the tx queue. For a similar stall to happen, the peer doesn't need to be a naive tcp implementation like nuttx. A naive application blocking on send() without draining its read buffer is enough. (Probably such an application should be fixed to drain rx even when tx is full. However, it's another story.) This commit avoids the situation by prevent tx from grabbing the all IOBs in the first place. (assuming CONFIG_IOB_THROTTLE > 0)		2021-07-14 15:08:18 +08:00
