Steps to reproduce: Following program shows the problem: #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <netinet/tcp.h> main() { int s = socket(AF_INET, SOCK_STREAM, 0); int val = 1; int len = sizeof(val); setsockopt(s, SOL_TCP, TCP_DEFER_ACCEPT, &val, len); listen(s, 1); getsockopt(s, SOL_TCP, TCP_DEFER_ACCEPT, &val, &len); printf("get TCP_DEFER_ACCEPT = %d\n", val); } On <=2.6.13 output is "get TCP_DEFER_ACCEPT = 3"; On >=2.6.14 output is "get TCP_DEFER_ACCEPT = 0". Starting from 2.6.14, defer_accept is moved to request_sock_queue structure, which is re-initialized in inet_csk_listen_start(). ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
