2019-01-07vcl/ldp: add locked sessions shim layerFlorin Coras7-1297/+890
Moves LDP logic that allows sharing of sessions between multi-process app workers into a separate VCL shim layer. Also refactors LDP to use the new layer. Change-Id: I8198b51eae7d099a8c486e36b29e3a0cb8cee8e9 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-01-05vcl/session: add api for changing session app workerFlorin Coras6-168/+368
In case of multi process apps, after forking, the parent may decide to close part or all of the sessions it shares with the child. Because the sessions have fifos allocated in the parent's segment manager, they must be moved to the child's segment manager.

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>
