2013-09-03bonding: use rlb_client_info->vlan_id instead of ->tagVeaceslav Falico1-1/+0
Store VID in ->vlan_id (if any), and remove the useless ->tag. CC: Jay Vosburgh <fubar@us.ibm.com> CC: Andy Gospodarek <andy@greyhouse.net> Signed-off-by: Veaceslav Falico <vfalico@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-08-29bonding: remove vlan_list/current_alb_vlanVeaceslav Falico1-1/+0
Currently there are no real users of vlan_list/current_alb_vlan, only the helpers which maintain them, so remove them.

2013-08-29bonding: make alb_send_learning_packets() use upper dev listVeaceslav Falico1-1/+0
Currently, if there are vlans on top of bond, alb_send_learning_packets() will never send LPs from the bond itself (i.e. untagged), which might leave untagged clients unupdated. Also, the 'circular vlan' logic (i.e. update only MAX_LP_BURST vlans at a time, and save the last vlan for the next update) is really suboptimal - in case of lots of vlans it will take a lot of time to update every vlan. It is also never called in any hot path and sends only a few small packets - thus the optimization by itself is useless. So remove the whole current_alb_vlan/MAX_LP_BURST logic from alb_send_learning_packets(). Instead, we'll first send a packet untagged and then traverse the upper dev list, sending a tagged packet for each vlan found. Also, remove the MAX_LP_BURST define - we already don't need it.

2012-11-30bonding: delete migrated IP addresses from the rlb hash tableJiri Bohac1-4/+24
Bonding in balance-alb mode records information from ARP packets passing through the bond in a hash table (rx_hashtbl). At certain situations (e.g. link change of a slave), rlb_update_rx_clients() will send out ARP packets to update ARP caches of other hosts on the network to achieve RX load balancing. The problem is that once an IP address is recorded in the hash table, it stays there indefinitely. If this IP address is migrated to a different host in the network, bonding still sends out ARP packets that poison other systems' ARP caches with invalid information. This patch solves this by looking at all incoming ARP packets, and checking if the source IP address is one of the source addresses stored in the rx_hashtbl. If it is, but the MAC addresses differ, the corresponding hash table entries are removed. Thus, when an IP address is migrated, the first ARP broadcast by its new owner will purge the offending entries of rx_hashtbl. The hash table is hashed by ip_dst. To be able to do the above check efficiently (not walking the whole hash table), we need a reverse mapping (by ip_src). I added three new members in struct rlb_client_info: rx_hashtbl[x].src_first will point to the start of a list of entries for which hash(ip_src) == x. The list is linked with src_next and src_prev. When an incoming ARP packet arrives at rlb_arp_recv() rlb_purge_src_ip() can quickly walk only the entries on the corresponding lists, i.e. the entries that are likely to contain the offending IP address. To avoid confusion, I renamed these existing fields of struct rlb_client_info: next -> used_next prev -> used_prev rx_hashtbl_head -> rx_hashtbl_used_head (The current linked list is _not_ a list of hash table entries with colliding ip_dst. It's a list of entries that are being used; its purpose is to avoid walking the whole hash table when looking for used entries.)

2011-04-25bonding: move processing of recv handlers into handle_frame()Jiri Pirko1-1/+0
Since now when bonding uses rx_handler, all traffic going into bond device goes thru bond_handle_frame. So there's no need to go back into bonding code later via ptype handlers. This patch converts original ptype handlers into "bonding receive probes". These functions are called from bond_handle_frame and they are registered per-mode. Note that vlan packets are also handled because they are always untagged thanks to vlan_untag() Note that this also allows arpmon for eth-bond-bridge-vlan topology.

2005-11-28[bonding] Remove superfluous changelog.Jeff Garzik1-9/+0
No need to record this information in source code, its all in the git repository, and kernel archives.
2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+141
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
