2017-10-04memif: crash on slave modeSteven1-0/+1
Crash was seen on recent image with this BT on top of the stack (gdb) bt full (mif=0x7fffb6226568) at /vpp/build-data/../src/plugins/memif/memif.c:297 ring = 0x0 <<<<<<<<<< i = 0 j = 0 buffer_offset = 65792 r = 0x7fffb5e59f80 alloc = {flags = 1, name = 0x7fffb449f965 "memif region", size = 4260096, numa_node = 0, addr = 0x7fff41dac000, fd = 11, log2_page_size = 12, n_pages = 1041} err = 0x0 __FUNCTION__ = "memif_init_regions_and_queues" The crash happened at this line. ring = memif_get_ring (mif, MEMIF_RING_S2M, i); ring=>head = ring->tail = 0; <===== Please note that the crash is caused by dereferencing NULL rinng. Put breakpoint into the function. I notice that mif->regions[0].shm is not initialized. (gdb) p mif->regions[0].shm $8 = (void *) 0x0 It looks like we forgot to set shm after clib_mem_vm_ext_alloc(). Add the missing cide and the crash is fixed. Change-Id: Ib722a6c241c77acfa8e33962106b57faa50e1ea7 Signed-off-by: Steven <sluong@cisco.com>
2017-10-03Repair vlib API socket serverDave Barach30-30/+16
- Teach vpp_api_test to send/receive API messages over sockets - Add memfd-based shared memory - Add api messages to create memfd-based shared memory segments - vpp_api_test supports both socket and shared memory segment connections - vpp_api_test pivot from socket to shared memory API messaging - add socket client support to libvlibclient.so - dead client reaper sends ping messages, container-friendly - dead client reaper falls back to kill (<pid>, 0) live checking if e.g. a python app goes silent for tens of seconds - handle ping messages in python client support code - teach show api ring about pairwise shared-memory segments - fix ip probing of already resolved destinations (VPP-998) We'll need this work to implement proper host-stack client isolation Change-Id: Ic23b65f75c854d0393d9a2e9d6b122a9551be769 Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Dave Wallace <dwallacelf@gmail.com> Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-09-27acl-plugin: take 2 at VPP-991 fix, this time with a test case which verifies it.Andrew Yourtchenko1-2/+2
The replacement of [] with pool_elt_at_index and subsequent fixing it was incorrect - it was equivalent to &[], since it returns a pointer to the element. I've added VPP-993 previously to create a testcase, so this commit partially fulfills that one as well.

2017-09-25Fix sending GARP/NA on Bonded Interface Active/Backup Link Up/DownJohn Lo2-24/+72
For bonded interface in Active/Backup mode (mode 1), we need to send a GARP/NA packet, if IP address is present, on slave link state change to up or down to help with route convergence. The callback from DPDK happens in a separate thread so we need to make sure RPC call is used to signal the send_garp_na process in the main thread. Also need to fix DPDK polling so the slave links are not polled. Change-Id: If5fd8ea2d28c54dd28726ac403ad366386ce9651 Signed-off-by: John Lo <loj@cisco.com>

2017-09-08memif: fix coverity warnings as of 9/7Steven4-12/+29
1. coverity complains about "buffer not null terminated" for strncpy because we pass the size of the destination to the call which is equal to the true size of the destination. We subtract 1 for the size to accommodate the null like all other places are already doing it. 2. Add a check to tx_queues in memif_interface_tx_inline to avoid "divide by zero". 3. To avoid null pointer dereference in memif_create_if, change the goto done rather than goto error and spit a more meaningful error rather than silent about it. 4. Shuffle a line to avoid "check after use" in vl_api_memif_delete_t_handler. Change-Id: Icba7ecd5362c012a48ac35795d31aab356617420 Signed-off-by: Steven <sluong@cisco.com>
