Hi all,
I have the same issue. After I built the vpp from sources(master branch)
and run vppctl I see a segmentation fault. This looks to be caused by the
fact that the vlib_mains from init functions of dynamic linked libraries is
0x0.
Following patch will fix the problem:
--- a/src/vlib/global_funcs.h
19 +++ b/src/vlib/global_funcs.h
20 @@ -23,7 +23,7 @@ always_inline vlib_main_t *
21 vlib_get_main (void)
22 {
23 vlib_main_t *vm;
24 - vm = vlib_mains[os_get_cpu_number ()];
25 + vm = vlib_mains ? vlib_mains[os_get_cpu_number ()] :
&vlib_global_main;
26 ASSERT (vm);
27 return vm;
28 }
This is like a part of patch did in commit:
80f54e20270ed0628ee725e3e3c515731a0188f2 need to be reverted.
Is other fix of this issue?
