The reserved ports will not be used by automatic port assignments (e.g. when calling connect() or bind() with port number 0). Explicit port allocation behavior is unchanged. Changes from the previous version: - switch the /proc entry format to coma separated list of range ports - treat -EFAULT just like any other error and acknowledge written values - use isdigit() in proc_get_ulong Octavian Purdila (3): sysctl: refactor integer handling proc code sysctl: add proc_do_large_bitmap net: reserve ports for applications using fixed port numbers Documentation/networking/ip-sysctl.txt | 14 + drivers/infiniband/core/cma.c | 7 +- include/linux/sysctl.h | 2 + include/net/ip.h | 6 + kernel/sysctl.c | 449 +++++++++++++++++++++----------- net/ipv4/af_inet.c | 8 +- net/ipv4/inet_connection_sock.c | 6 + net/ipv4/inet_hashtables.c | 2 + net/ipv4/sysctl_net_ipv4.c | 17 ++ net/ipv4/udp.c | 3 +- net/sctp/socket.c | 2 + 11 files changed, 361 insertions(+), 155 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
