Atsushi Nemoto writes:
I found inappropriate data types are used in some places in networking codes. * tcp_seq is 32bit (u_long -> u_int32_t) * in_addt_t should be used for internet address (unsigned long -> in_addr_t) * socklen_t should be used for accept() This is a patch against uclibc-0.9.21 (can be applied for current CVS). 64bit platforms (sizeof(int)!=sizeof(long)) will need this. I believe this patch does not harm any 32bit platforms.
