2017-06-02vhost: add debug vhost-user on | off CLISteven2-20/+59
Add runtime debug vhost-user on | off CLI to facilitate troubleshooting. This feature is needed to avoid recompiling the code to debug vhost issues. The debugging messages should not be on the data path to avoid performance hit. Change-Id: I4c40f65dbb222557cba3fb8706fa3b7b62eec95f Signed-off-by: Steven <sluong@cisco.com>

2017-05-29memif: master instance crashes when typing quit on slaveSteven1-15/+29
When I type in 'quit' on the slave instance, the master instance crashes on this line. 0: /home/sluong/vpp-master/vpp/build-data/../src/vlib/unix/input.c:200 (linux_epoll_input) assertion `! pool_is_free (um->file_pool, _e)' fails Aborted (core dumped) Below is the decode from gdb line_number=0, fmt=0x7f57af6cc9a0 "%s:%d (%s) assertion `%s' fails") at /home/sluong/vpp-master/vpp/build-data/../src/vppinfra/error.c:143 vm=0x7f57af8e2400 <vlib_global_main>, node=0x7f576d40ad80, frame=0x0) at /home/sluong/vpp-master/vpp/build-data/../src/vlib/unix/input.c:200 vm=0x7f57af8e2400 <vlib_global_main>, node=0x7f576d40ad80, type=VLIB_NODE_TYPE_PRE_INPUT, dispatch_state=VLIB_NODE_STATE_POLLING, frame=0x0, last_time_stamp=1525665215050617) at /home/sluong/vpp-master/vpp/build-data/../src/vlib/main.c:1016 vm=0x7f57af8e2400 <vlib_global_main>, is_main=1) at /home/sluong/vpp-master/vpp/build-data/../src/vlib/main.c:1500 I am able to reproduce the problem consistently with the below procedure. 1. Create 3 memif interfaces between slave and master instances. 2. Type 'quit' on the slave. Neither crashes the first time. 3. Bring back the slave. Type 'quit' on the master. Neither crashes. 4. Bring back the master. Type 'quit' on the slave. The master crashes. There are two places the interrupt line is disconnected and the unix file is removed via the call unix_file_del () 1. memif_int_fd_read_ready () 2. memif_disconnect () which is called via multiple places in memif. When the crash happens, the unix file was removed from memif_disconnect () via memif_conn_fd_read_ready () with size of the message == 0 in recvmsg (). It is noted when the unix file was removed from memif_int_fd_read_ready (), it never crashes. It is a race condition. However, if I follow the aformentioned procedure, the crash always happens. The reason the crash happens when memif_disconnect () removes the unix file is because there may still be pending input in linux_epoll_input (). When linux_epoll_input () tries to access the unix file via the line 200 unix_file_t *f = pool_elt_at_index (um->file_pool, i); it crashes. We could add code in linux_epoll_input () to avoid the crash if the index for the particular file_pool is already free. Or we could fix memif to not remove the unix file in memif_conn_fd_read_ready () when recvmsg () got 0 byte and just postpone the unix file deletion in memif_int_fd_read_ready () later after linux_epoll_input () got a chance to run to empty the input stream. I choose to fix the problem in the latter approach. I split the function memif_disconnect () into two parts. For the code path which memif_conn_fd_read_ready () calls memif_disconnect (), it does not remove the unix file. All other calls to memif_disconnect () will continue to do what it uses to do to avoid regression. Please let me know if I should fix the problem other way.

2017-05-23ARP/ND entries for the same address on different interfaces (VPP-848)Neale Ranns18-735/+1194
there are, intentionally, no validation checks in the ARP/ND code to prevent an ARP/ND entry from being installed for an address that is not local to the interface's sub-net. This is ok, since the adjacency/FIB code is designed to handle this case using the 'refinement' criteria - i.e. only installing a FIB entry for the address if the address 'refines' (i.e. is more specific than) the interface's sub-net. However, the refinement criteria currently operates on the FIB entry's prefix (which is a /32, so on the address) and not on the next-hop in the path. So, enter multiple ARP entries for the same address on different links, and this refinement criteria uses only the last added path, and so will remove the FIB entry should the ARP entries be added in the 'wrong' order. This fix updates the refinement criteria to work on each path of the FIB entry. The entry is installed if one of the paths refines the covers and only paths refining the cover contribute forwarding. Per-path refinement checks are stored in path-extensions. The patch is rather large as path-extension, which were previously used only for out-going MPLS labels, have been generalized.

2017-05-22vhost: migrate to use device infra for worker thread assignment, rx-mode.Steven6-556/+342
and add adaptive mode support to receive queue - Migrate vhost to use device infra which does the interface/queue to worker thread assignment. - Retire vhost thread CLI and corresponding code which assigns interface/queue to worker thread. set interface placement should be used instead to customize the interface/queue to worker thread assignment. - Retire vhost interrupt/polling option when creating vhost-user interface. Instead, set interface rx-mode should be used. - Add code in vnet_device_input_unassign_thread to change the node state to interrupt if the last polling interface has left the worker thread for the device of the corresponding interface/queue. - Add adaptive mode support. The node state is set to interrupt initially. When the scheduler detects a burst of traffic, it switches the input node to polling. Then we inform the device that we don't need interrupt notification. When the traffic subsides, the scheduler switches the input node back to interrupt. Then we immediately tell the driver that we want interrupt notification again. - Remove some duplicate code in vlib/main.c Change-Id: Id19bb1b9e50e6521c6464f470f5825c26924d3a8 Signed-off-by: Steven <sluong@cisco.com>

2017-05-20vhost: buffers leak and interface disable upon vring descriptor out of mmapSteven1-16/+9
When processing a vring descriptor which is outside of mmap, we disable the interface and spit a message to shut/no shut the interface. This is not practical as application using vhost cannot constantly checking the logs and do the recovery. The proposed fix is to log an error, like other errors that we encounter. The other bug is buffer leak in the function rewind. At the end of the while loop when b_current != b_head, we still have to give back 1 more buffer or add 1 to rx_buffers_len.

Prior to commit bfd9227e6da567e0e19e026afe94cd4c0b65f725, there was no clean way to check the lower-level message length as supplied by the client, so there was no option but to trust that the client does the right thing and allocates memory correctly. The absence of checks makes it hard for a misbehaving client to spot the problem - because everything "appears" to work correctly for the specific erroneous message exchange. This commit ensures the message received is at least as big as we expect, and complains loudly if it is not.
