void bond_activebackup_arp_mon ( struct work_struct *  )

Definition at line 3171 of file bond_main.c.

void bond_change_active_slave ( struct bonding *  bond,
struct slave *  new_active 
)

change_active_interface - change the active slave into the specified one : our bonding struct : the new slave to make the active one

Set the new slave to the bond's settings and unset them on the old curr_active_slave. Setting include flags, mc-list, promiscuity, allmulti, etc.

If 's link state is BOND_LINK_BACK we'll set it to BOND_LINK_UP, because it is apparently the best available slave we have, even though its updelay hasn't timed out yet.

If new_active is not NULL, caller must hold bond->lock for read and curr_slave_lock for write_bh.

bond_next_vlan - safely skip to the next item in the vlans list. : the bond we're working on : item we're advancing from

Returns NULL if list is empty, bond->next_vlan if is NULL, or ->next otherwise (even if it is itself again).

Caller must hold bond->lock

void bond_select_active_slave ( struct bonding *  bond)

bond_select_active_slave - select a new active slave, if needed : our bonding struct

This functions should be called when one of the following occurs:

  • The old curr_active_slave has been released or lost its link.
  • The primary_slave has got its link back.
  • A slave has got its link back and there's no old curr_active_slave.

Caller must hold bond->lock for read and curr_slave_lock for write_bh.
