[lwip-devel] recv_avail field of netconn structure

[Stathis Voukelatos]

Hi,

 

If LWIP_SO_RCVBUF is defined then the netconn structure contains the recv_avail field

to store the number of bytes currently sitting in the recvmbox of the netconn.

In lwip 1.4.1 the type of recv_avail is ‘s16_t’, which can cause it to overflow for large

receive buffer sizes. Should it not be an ‘int’ just as the recv_bufsize that it is compared

against?

 

Cheers,

Stathis
