2018-11-08Calculate clock rounding constantDave Barach1-3/+18
Compute the first power of ten which is greater than 0.1% of the clock rate. Save the result, and use it to round future results. The previous constant value - 1e7 - didn't work properly on aarch64. Change-Id: Ic021e3eb1b90c0d4a7d9f1b6425123f0c8b48b0b Signed-off-by: Dave Barach <dave@barachs.net>

2018-09-07Improve NTP / kernel time change event handlingDave Barach1-0/+20
clib_time_verify_frequency(...) rejects clock frequency changes greater than 1%. vlib_worker_thread_barrier_sync_int (...) continuously checks that the barrier hold-down timer is not unreasonably far in the future.

2017-10-03Repair vlib API socket serverDave Barach1-2/+2
- 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>
