Hello VPP experts,
When trying the current VPP master branch using a debug build we
encountered an assertion failure in vlib_time_now() here:
always_inline f64
vlib_time_now (vlib_main_t * vm)
{
#if CLIB_DEBUG > 0
extern __thread uword __os_thread_index;
#endif
/*
* Make sure folks don't pass &vlib_global_main from a worker thread.
*/
ASSERT (vm->thread_index == __os_thread_index);
return clib_time_now (&vm->clib_time) + vm->time_offset;
}
The ASSERT there is triggered because the LACP code passes
&vlib_global_main when it should pass a thread-specific vlib_main_t. So
this looks like precisely the kind of issue that the assertion was made
to catch.
To reproduce the problem I think it should be anough to use LACP in a
multi-threaded scenario, using a debug build, then the assertion
failure happens directy at startup, every time.
I pushed a fix, here: https://gerrit.fd.io/r/c/vpp/+/26943
After that fix it seems to work, LACP then works without assertion
failure. Please have a look and merge if it seems okay.
Best regards,
Elias
