last_synq_overflow eats 4 or 8 bytes in struct tcp_sock, even though it is only used when a listening sockets syn queue is full. We can (ab)use rx_opt.ts_recent_stamp to store the same information; it is not used otherwise as long as a socket is in listen state. Move linger2 around to avoid splitting struct mtu_probe across cacheline boundary on 32 bit arches. Signed-off-by:

We can in some situations drop packets in netif_rx() loopback driver does not report these (unlikely) drops to its stats, and incorrectly change packets/bytes counts. After this patch applied, "ifconfig lo" can reports these drops as in : # ifconfig lo lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:692562900 errors:3228 dropped:3228 overruns:0 frame:0 TX packets:692562900 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2865674174 (2.6 GiB) TX bytes:2865674174 (2.6 GiB) I initialy chose to reflect those errors only in tx_dropped/tx_errors, but David convinced me that it was really RX errors, as loopback_xmit() really starts a RX process. (calling eth_type_trans() for example, that itself pulls the ethernet header) These errors are accounted in rx_dropped/rx_errors. Signed-off-by:Eric Dumazet <dada1@cosmosbay.com> Signed-off-by:

As reported by Andrew Lutomirski <amluto@gmail.com> All the intel wired ethernet drivers were calling netif_carrier_off and netif_stop_queue (or variants) before calling register_netdevice This is incorrect behavior as was pointed out by davem, and causes ifconfig and friends to report a strange state before first link after the driver was loaded. This apparently confused *some* versions of networkmanager. Andy tested this for e1000e and confirmed it was working for him. Signed-off-by:

inet_register_protosw() function is responsible for adding a new inet protocol into a global table (inetsw[]) that is used with RCU rules. As soon as the store of the pointer is done, other cpus might see this new protocol in inetsw[], so we have to make sure new protocol is ready for use. All pending memory updates should thus be committed to memory before setting the pointer. This is correctly done using rcu_assign_pointer() synchronize_net() is typically used at unregister time, after unsetting the pointer, to make sure no other cpu is still using the object we want to dismantle. Using it at register time is only adding an artificial delay that could hide a real bug, and this bug could popup if/when synchronize_rcu() can proceed faster than now. This saves about 13 ms on boot time on a HZ=1000 8 cpus machine ;) (4 calls to inet_register_protosw(), and about 3200 us per call) Signed-off-by:

Force a statistics update when our ethtool gstats routine is called. Otherwise, ethtool will continue to read stale stats until something forces an update by reading /proc/net/dev This requires putting a lock around the stats update to guard against 2 threads (one via ethtool, and one via procfs) updating the stats at once.

The removal of the SAME target accidentally removed one feature that is not available from the normal NAT targets so far, having multi-range mappings that use the same mapping for each connection from a single client. The current behaviour is to choose the address from the range based on source and destination IP, which breaks when communicating with sites having multiple addresses that require all connections to originate from the same IP address. Introduce a IP_NAT_RANGE_PERSISTENT option that controls whether the destination address is taken into account for selecting addresses. http://bugzilla.kernel.org/show_bug.cgi?id=12954Signed-off-by:
