2019-08-27session: move ctrl messages from bapi to mqFlorin Coras9-106/+675
Type:refactor Moves connect, disconnect, bind, unbind and app detach to message queue from binary api. Simplifies app/vcl interaction with the session layer since all session control messages are now handled over the mq. Add/del segment messages require internal C api changes which affect all builtin applications. They'll be moved in a different patch and might not be back portable to 19.08.

2019-08-19dns: handle multiple replies for single requestsDave Barach3-59/+121
The world is a mess. A single DNS request may yield multiple, subtly different responses; all with the same DNS protocol-level ID. Last response wins in terms of what ends up in the cache.

2019-08-17bonding lacp: deleting virtual interface which was enslaved may cause crashSteven Luong3-26/+39
Virtual interfaces may be part of the bonding like physical interfaces. The difference is virtual interfaces may disappear dynamically. As an example, the following CLI sequence may crash the debug image create vhost-user socket /tmp/sock1 create bond mode lacp bond add BondEthernet0 VirtualEthernet0/0/0 delete vhost-user VirtualEhernet0/0/0 Notice the virtual interface is deleted without first doing bond delete. The proper order is to first remove the slave interface from the bond prior to deleting the virtual interface as shown below. But we should handle it anyway. create vhost-user socket /tmp/sock1 create bond mode lacp bond add BondEthernet0 VirtualEthernet0/0/0 bond del VirtualEthernet0/0/0 <----- delete vhost-user VirtualEhernet0/0/0 The fix is to register for VNET_SW_INTERFACE_ADD_DEL_FUNCTION and remove the slave interface from the bond if the to-be-deleted interface is part of the bond. We check the interface that it is actually up before we send the lacp pdu. Up means both hw and sw admin up.

2019-08-16devices: vhost-user crashes displaying show trace for deleted interfaceSteven Luong1-6/+10
After the trace is collected and if the interface is then deleted, show trace may crash for the debug image. This is due to the additional check in pool_elt_at_index() to make sure that the block is not free. The fix is to do the check in vhost format trace and return "interface deleted" Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I0744f913ba6146609663443f408d784067880f93

2019-08-15vlib: copy trace_handle in vlib_buffer_copy/clone() functionsJohn Lo5-15/+1
