2011-12-06ipv4:correct description for tcp_max_syn_backlogPeter Pan(潘卫平)
Since commit c5ed63d66f24(tcp: fix three tcp sysctls tuning), sysctl_max_syn_backlog is determined by tcp_hashinfo->ehash_mask, and the minimal value is 128, and it will increase in proportion to the memory of machine. The original description for tcp_max_syn_backlog and sysctl_max_syn_backlog are out of date.

2011-09-16ipv6: Send ICMPv6 RSes only when RAs are acceptedTore Anderson
This patch improves the logic determining when to send ICMPv6 Router Solicitations, so that they are 1) always sent when the kernel is accepting Router Advertisements, and 2) never sent when the kernel is not accepting RAs. In other words, the operational setting of the "accept_ra" sysctl is used. The change also makes the special "Hybrid Router" forwarding mode ("forwarding" sysctl set to 2) operate exactly the same as the standard Router mode (forwarding=1). The only difference between the two was that RSes was being sent in the Hybrid Router mode only. The sysctl documentation describing the special Hybrid Router mode has therefore been removed. Rationale for the change: Currently, the value of forwarding sysctl is the only thing determining whether or not to send RSes. If it has the value 0 or 2, they are sent, otherwise they are not. This leads to inconsistent behaviour in the following cases: * accept_ra=0, forwarding=0 * accept_ra=0, forwarding=2 * accept_ra=1, forwarding=2 * accept_ra=2, forwarding=1 In the first three cases, the kernel will send RSes, even though it will not accept any RAs received in reply. In the last case, it will not send any RSes, even though it will accept and process any RAs received. (Most routers will send unsolicited RAs periodically, so suppressing RSes in the last case will merely delay auto-configuration, not prevent it.) Also, it is my opinion that having the forwarding sysctl control RS sending behaviour (completely independent of whether RAs are being accepted or not) is simply not what most users would intuitively expect to be the case.

2011-06-08inetpeer: remove unused listEric Dumazet
Andi Kleen and Tim Chen reported huge contention on inetpeer unused_peers.lock, on memcached workload on a 40 core machine, with disabled route cache. It appears we constantly flip peers refcnt between 0 and 1 values, and we must insert/remove peers from unused_peers.list, holding a contended spinlock. Remove this list completely and perform a garbage collection on-the-fly, at lookup time, using the expired nodes we met during the tree traversal. This removes a lot of code, makes locking more standard, and obsoletes two sysctls (inet_peer_gc_mintime and inet_peer_gc_maxtime). This also removes two pointers in inet_peer structure. There is still a false sharing effect because refcnt is in first cache line of object [were the links and keys used by lookups are located], we might move it at the end of inet_peer structure to let this first cache line mostly read by cpus.

2011-04-29ipv4, ipv6, bonding: Restore control over number of peer notificationsBen Hutchings
For backward compatibility, we should retain the module parameters and sysfs attributes to control the number of peer notifications (gratuitous ARPs and unsolicited NAs) sent after bonding failover. Also, it is possible for failover to take place even though the new active slave does not have link up, and in that case the peer notification should be deferred until it does. Change ipv4 and ipv6 so they do not automatically send peer notifications on bonding failover. Change the bonding driver to send separate NETDEV_NOTIFY_PEERS notifications when the link is up, as many times as requested. Since it does not directly control which protocols send notifications, make num_grat_arp and num_unsol_na aliases for a single parameter. Bump the bonding version number and update its documentation.
