2018-09-11remove libvlib from libvlibmemoryclient libsMatthew Smith1-1/+1
On CentOS 7, having libvlibmemoryclient link libvlib causes a SEGV when a program or library is run which links against libvlibmemoryclient and dlopen() is called. This is because dlopen() executes any functions with __attribute((constructor)) set. The VLIB_CLI_COMMAND macro creates CLI registration functions that have this attribute set. So CLI registration functions end up being run by applications which are clients of the VPP API. This doesn't occur on ubuntu 16.04, because ld seems to omit shared libraries that were listed on the command line if they are not used to resolve any symbols. Removing the link to libvlib on vlibmemoryclient to fix this problem results in another problem. Tests of libvcl_preload fail when running 'make test'. This happens because libvcl_preload calls dlopen but does not link against libdl. When libvlibmemoryclient had libvlib linked, these errors did not occur since libvlib links libdl. Adjusted the build of libvcl_preload to explicitly link libdl. Change-Id: I271ba2f9226ce1602e1f6c1525f3b093bb0345ed Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2018-08-10vcl: support for eventfd mq signalingFlorin Coras8-599/+1063
- support eventfd based mq signaling. Based on configuration, vcl epoll/select can use either condvars or epoll on mq eventfds. - add vcl support for memfd segments - vpp explicitly registers cut-through segments with apps/vcl - if using eventfd, make ldp allow one call to libc_epoll_create. Needed for the message queue epfd - update svm_queue_t to allow blocking calls with eventfd signaling.

2018-07-27vcl: use events for epoll/select/read/writeFlorin Coras10-695/+1023
Have vcl poll and wait on the event message queues as opposed to constantly polling the session fifos. This also adds event signaling to cut through sessions. On the downside, because we can't wait on multiple condvars, i.e., when we have multiple message queues because of cut-through registrations, we do timed waits.
