2012-08-14sctp: Make the port hash table use struct net in it's key.Eric W. Biederman
- Add struct net into the port hash table hash calculation - Add struct net inot the struct sctp_bind_bucket so there is a memory of which network namespace a port is allocated in. No need for a ref count because sctp_bind_bucket only exists when there are sockets in the hash table and sockets can not change their network namspace, and sockets already ref count their network namespace. - Add struct net into the key comparison when we are testing to see if we have found the port hash table entry we are looking for. With these changes lookups in the port hash table becomes safe to use in multiple network namespaces. Signed-off-by: "Eric W.

2012-08-09net: Make ifindex generation per-net namespacePavel Emelyanov
Strictly speaking this is only _really_ required for checkpoint-restore to make loopback device always have the same index. This change appears to be safe wrt "ifindex should be unique per-system" concept, as all the ifindex usage is either already made per net namespace of is explicitly limited with init_net only. There are two cool side effects of this. The first one -- ifindices of devices in container are always small, regardless of how many containers we've started (and re-started) so far. The second one is -- we can speed up the loopback ifidex access as shown in the next patch. v2: Place ifindex right after dev_base_seq : avoid two holes and use the same cache line, dirtied in list_netdevice()/unlist_netdevice() Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2012-08-09veth: Allow to create peer link with given ifindexPavel Emelyanov
The ifinfomsg is in there (thanks kaber@ for foreseeing this long time ago), so take the given ifidex and register netdev with it. Ben noticed, that this code path previously ignored ifmp->ifi_index and userland could be passing in garbage. Thus it may now fail occasionally because the value clashes with an existing interface. To address this it's assumed that if the caller specifies the ifindex for the veth master device, then it's aware of this possibility and should explicitly specify (or set to 0 for auto-assignment) the peer's ifindex as well. With this the compatibility with old tools not setting ifindex is preserved. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-08-09net: Allow to create links with given ifindexPavel Emelyanov
Currently the RTM_NEWLINK results in -EOPNOTSUPP if the ifinfomsg->ifi_index is not zero. I propose to allow requesting ifindices on link creation. This is required by the checkpoint-restore to correctly restore a net namespace (i.e. -- a container).

2012-08-09net: Dont use ifindices in hash fnsPavel Emelyanov
Eric noticed, that when there will be devices with equal indices, some hash functions that use them will become less effective as they could. Fix this in advance by mixing the net_device address into the hash value instead of the device index. This is true for arp and ndisc hash fns. The netlabel, can and llc ones are also ifindex-based, but that three are init_net-only, thus will not be affected. Many thanks to David and Eric for the hash32_ptr implementation!

2012-08-09time: jiffies_delta_to_clock_t() helper to the rescueEric Dumazet
Various /proc/net files sometimes report crazy timer values, expressed in clock_t units. This happens when an expired timer delta (expires - jiffies) is passed to jiffies_to_clock_t(). This function has an overflow in : return div_u64((u64)x * TICK_NSEC, NSEC_PER_SEC / USER_HZ); commit cbbc719fccdb8cb (time: Change jiffies_to_clock_t() argument type to unsigned long) only got around the problem. As we cant output negative values in /proc/net/tcp without breaking various tools, I suggest adding a jiffies_delta_to_clock_t() wrapper that caps the negative delta to a 0 value.

2012-08-06tcp: ecn: dont delay ACKS after CEEric Dumazet
While playing with CoDel and ECN marking, I discovered a non optimal behavior of receiver of CE (Congestion Encountered) segments. In pathological cases, sender has reduced its cwnd to low values, and receiver delays its ACK (by 40 ms). While RFC 3168 6.1.3 (The TCP Receiver) doesn't explicitly recommend to send immediate ACKS, we believe its better to not delay ACKS, because a CE segment should give same signal than a dropped segment, and its quite important to reduce RTT to give ECE/CWR signals as fast as possible. Note we already call tcp_enter_quickack_mode() from TCP_ECN_check_ce() if we receive a retransmit, for the same reason.

2012-08-06net: tcp: GRO should be ECN friendlyEric Dumazet

I have yet to understand how to solve this problem. 2) GRO is not ECN friendly Delivering packets out of order makes TCP stack not as fast as it could be.

AR1111 is same as AR9485. The h/w difference between them is quite insignificant, Felix suggests only very few baseband features may not be available in AR1111. The h/w code for AR9485 is already present, so AR1111 should work fine with the addition of its PID/VID.
