tcp_shutdown in net/ipv4/tcp.c begins with:
void tcp_shutdown(struct sock *sk, int how) { /* We need to grab some memory, and put together a FIN, * and then put it into the queue to be sent. * Tim MacKenzie(tym@dibbler.cs.monash.edu.au) 4 Dec '92. */ if (!(how & SEND_SHUTDOWN)) return;
It looks to me like this misinterprets the how value. how == 1 should mean no more sends, but here SEND_SHUTDOWN is 2 and so some shutdown calls on tcp sockets will get wrongly ignored.
