This is the second step for neighbour RCU conversion. (first was commit d6bf7817 : RCU conversion of neigh hash table) neigh_lookup() becomes lockless, but still take a reference on found neighbour. (no more read_lock()/read_unlock() on tbl->lock) struct neighbour gets an additional rcu_head field and is freed after an RCU grace period. Future work would need to eventually not take a reference on neighbour for temporary dst (DST_NOCACHE), but this would need dst->_neighbour to use a noref bit like we did for skb->_dst.

When an interface was enslaved when it was down, bonding thinks it has speed -1 even after it goes up. This leads into selecting a wrong active interface in active/backup mode on mixed 10G/1G or 1G/100M environment. before: bonding: bond0: link status definitely up for interface eth5, 100 Mbps full duplex. bonding: bond0: link status definitely up for interface eth0, 100 Mbps full duplex. after: bonding: bond0: link status definitely up for interface eth5, 10000 Mbps full duplex. bonding: bond0: link status definitely up for interface eth0, 1000 Mbps full duplex.

Flavio Leitner authored
The IGMP specs states that if the system receives a membership report, it shouldn't send another for the next minute. However, if a link failure happens right after that, the backup slave and the switch connected to this slave will not know about the multicast and the traffic will hang for about a minute. This patch fixes it to rejoin multicast groups immediately after a failover restoring the multicast traffic. Signed-off-by:

During a failover, the IGMP membership is sent to update the switch restoring the traffic, but it misses groups added to VLAN devices running on top of bonding devices. This patch changes it to iterate over all VLAN devices on top of it sending IGMP memberships too. Signed-off-by:

David This is the first step for RCU conversion of neigh code. Next patches will convert hash_buckets[] and "struct neighbour" to RCU protected objects. Thanks [PATCH net-next] net neigh: RCU conversion of neigh hash table Instead of storing hash_buckets, hash_mask and hash_rnd in "struct neigh_table", a new structure is defined : struct neigh_hash_table { struct neighbour **hash_buckets; unsigned int hash_mask; __u32 hash_rnd; struct rcu_head rcu; }; And "struct neigh_table" has an RCU protected pointer to such a neigh_hash_table. This means the signature of (*hash)() function changed: We need to add a third parameter with the actual hash_rnd value, since this is not anymore a neigh_table field. Signed-off-by: -

In various situations, a device provides a packet to our stack and we drop it before it enters protocol stack : - softnet backlog full (accounted in /proc/net/softnet_stat) - bad vlan tag (not accounted) - unknown/unregistered protocol (not accounted) We can handle a per-device counter of such dropped frames at core level, and automatically adds it to the device provided stats (rx_dropped), so that standard tools can be used (ifconfig, ip link, cat /proc/net/dev) This is a generalization of commit 8990f468 (net: rx_dropped accounting), thus reverting it.

Qemu supports up to UIO_MAXIOV s/g so we have to match that because guest drivers may rely on this. Allocate indirect and log arrays dynamically to avoid using too much contigious memory and make the length of hdr array to match the header length since each iovec entry has a least one byte. Test with copying large files w/ and w/o migration in both linux and windows guests. Signed-off-by:
