2017-06-07VPP-873: fix vector expansion bug in dispatch_pending_nodeDave Barach1-13/+27
The main interior graph-node dispatch loop had a longstanding dangling vector element reference: for (i = 0; i < _vec_len (nm->pending_frames); i++) cpu_time_now = dispatch_pending_node (vm, nm->pending_frames + i, cpu_time_now); Passing a pointer to a vector element (nm->pending_frames + i) has considerable comedic potential if there's any chance that the vector could expand. dispatch_pending_node() calls dispatch_node(), and indirectly any interior graph node dispatch function. If that node happens to expand nm->pending_frames by filling in a new frame, nm->pending_frames can expand. After calling the node dispatch function, dispatch_node() does the following: nf = vec_elt_at_index (nm->next_frames, p->next_frame_index); If nm->pending_frames expands during dispatch function execution, p is a dangling reference to freed memory. By luck, the TCP stack managed to allocate a fresh frame which included "old-p," which caused p->next_frame_index to be filled with the new-frame poison pattern 0xfefefefe. This has been broken from day 1, summer 2007, first use of the third-generation vector processing library.

2017-06-07acl-plugin: fix coverity error in acl_test.cAndrew Yourtchenko1-2/+2
Attempting to supply within a VAT CLI to add the ACLs a rule count override with no rules to add would result in null pointer dereference as we attempt to copy those rules to the message. Add the check to avoid copy if the source pointer is null (i.e. if there are no rules to copy from). This commit fixes coverity errors 166797 and 166792.

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.
