hi all,
I have a question about policer classify.
The code of bind/unbind a policer with interface is:
if (is_add)
pcm->classify_table_index_by_sw_if_index[ti][sw_if_index] = pct[ti];
else
pcm->classify_table_index_by_sw_if_index[ti][sw_if_index] = ~0;
and the code checking the value in "ip4-policer-classify" node is:
table_index0 =
pcm->classify_table_index_by_sw_if_index[tid][sw_if_index0];
There is no lock protecting the table index.
The function of policer is ok in multi-thread vpp, but I don't know why it is
lock-free.
Can any one help?
Thanks.
