* net: igmp: Reduce Unsolicited report interval to 1s when using IGMPv3William Manley2013-08-091-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | If an IGMP join packet is lost you will not receive data sent to the multicast group so if no data arrives from that multicast group in a period of time after the IGMP join a second IGMP join will be sent. The delay between joins is the "IGMP Unsolicited Report Interval". Previously this value was hard coded to be chosen randomly between 0-10s. This can be too long for some use-cases, such as IPTV as it can cause channel change to be slow in the presence of packet loss. The value 10s has come from IGMPv2 RFC2236, which was reduced to 1s in IGMPv3 RFC3376. This patch makes the kernel use the 1s value from the later RFC if we are operating in IGMPv3 mode. IGMPv2 behaviour is unaffected. Tested with Wireshark and a simple program to join a (non-existent) multicast group. The distribution of timings for the second join differ based upon setting /proc/sys/net/ipv4/conf/eth0/force_igmp_version.

* bonding: unwind on bond_add_vlan failurenikolay@redhat.com2013-08-091-2/+2
| | | | | | | | | | | In case of bond_add_vlan() failure currently we'll have the vlan's refcnt bumped up in all slaves, but it will never go down because it failed to get added to the bond, so properly unwind the added vlan if bond_add_vlan fails.

* bonding: change the bond's vlan syncing functions with the standard onesnikolay@redhat.com2013-08-091-30/+7Star
| | | | | | | | | | | | | | | Now we have vlan_vids_add/del_by_dev() which serve the same purpose as bond's bond_add/del_vlans_on_slave() with the good side effect of reverting the changes if one of the additions fails. There's only 1 change in the behaviour of enslave: if adding of the vlans to the slave fails, we'll fail the enslaving because otherwise we might delete some vlan that wasn't added by the bonding. The only way this may happen is with ENOMEM currently, so we're in trouble anyway.

* net: add SNMP counters tracking incoming ECN bitsEric Dumazet2013-08-095-2/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With GRO/LRO processing, there is a problem because Ip[6]InReceives SNMP counters do not count the number of frames, but number of aggregated segments. Its probably too late to change this now. This patch adds four new counters, tracking number of frames, regardless of LRO/GRO, and on a per ECN status basis, for IPv4 and IPv6. Ip[6]NoECTPkts : Number of packets received with NOECT Ip[6]ECT1Pkts : Number of packets received with ECT(1) Ip[6]ECT0Pkts : Number of packets received with ECT(0) Ip[6]CEPkts : Number of packets received with Congestion Experienced lph37:~# nstat | egrep "Pkts|InReceive" IpInReceives 1634137 0.0 Ip6InReceives 3714107 0.0 Ip6InNoECTPkts 19205 0.0 Ip6InECT0Pkts 52651828 0.0 IpExtInNoECTPkts 33630 0.0 IpExtInECT0Pkts 15581379 0.0 IpExtInCEPkts 6 0.0 Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | Both [eTSEC76] and [eTSEC12] errata relate to Tx checksum generation (for some MPC83xx and MCP8548 older revisions). They require the same workaround: manual checksum computation and insertion, and disabling the H/W Tx csum acceleration feature (per frame) through Tx FCB (Frame Control Block) csum offload settings. The workaround for [eTSEC76] needs to be fixed because it currently fails to disable H/W Tx csum insertion via FCB. This patch fixes it and provides a common workaround implementation for both Tx csum errata. Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S.

* bonding: remove locking from bond_set_rx_mode()Veaceslav Falico2013-08-051-6/+4Star
| | | | | | | | | | | | | | | | | | | We're already protected by RTNL lock, so nothing can happen to bond/its slaves, and thus the locking is useless here (both bond->lock and bond->curr_active_slave). Also, add ASSERT_RTNL() both to bond_set_rx_mode() and bond_hw_addr_swap() to catch possible uses of it without RTNL locking. This patch also saves us from a lockdep false-positive in bond_set_rx_mode() vs bond_hw_addr_swap().

* bonding: add bond_time_in_interval() and use it for time comparisonVeaceslav Falico2013-08-051-53/+32Star
| | | | | | | | | | | | | | | | | | | | | | | Currently we use a lot of time comparison math for arp_interval comparisons, which are sometimes quite hard to read and understand. All the time comparisons have one pattern: (time - arp_interval_jiffies) <= jiffies <= (time + mod * arp_interval_jiffies + arp_interval_jiffies/2) Introduce a new helper - bond_time_in_interval(), which will do the math in one place and, thus, will clean up the logical code. This helper introduces a bit of overhead (by always calculating the jiffies from arp_interval), however it's really not visible, considering that functions using it usually run once in arp_interval milliseconds. There are several lines slightly over 80 chars, however breaking them would result in more hard-to-read code than several character after the 80 mark.

* ax88179_178a: avoid copy of tx tcp packetsEric Dumazet2013-08-041-17/+4Star
| | | | | | | | | | | | | | | | | | ax88179_tx_fixup() has quite complex code trying to push 8 bytes of control data (len/mss), but fails to do it properly for TCP packets, incurring an extra copy and point of memory allocation failure. Lets use the simple and approved way. dev->needed_headroom being 8, all frames should have 8 bytes of headroom, so the extra copy should be unlikely anyway. This patch should improve performance for TCP xmits.
