Why does cfm_generate_maid() need the mutex? It doesn't seem to use
any static data and when it is called the new struct cfm isn't visible
outside the running thread.
Can all_cfms be a const pointer, e.g:
static struct hmap *const all_cfms OVS_GUARDED_BY(mutex) = &all_cfms__;
I think there's at least one deadlock. cfm_unixctl_show() takes the
lock, calls cfm_print_details(), which calls cfm_get_fault(), which
takes the lock.
The caller can't use cfm_get_remote_mpids()'s returned data in a
race-free way.
Thanks,
Ben.
