> (cherry picked from commit 033b228e7f26b29ae37f8bfa1bc6b209a5365e9f) > > When tcindex_destroy() destroys all the filter results in > the perfect hash table, it invokes the walker to delete > each of them. However, results with class==0 are skipped > in either tcindex_walk() or tcindex_delete(), which causes > a memory leak reported by kmemleak. > > This patch fixes it by skipping the walker and directly > deleting these filter results so we don't miss any filter > result. > > As a result of this change, we have to initialize exts->net > properly in tcindex_alloc_perfect_hash(). For net-next, we > need to consider whether we should initialize ->net in > tcf_exts_init() instead, before that just directly test > CONFIG_NET_CLS_ACT=y. > > Cc: Jamal Hadi Salim <j...@mojatatu.com> > Cc: Jiri Pirko <j...@resnulli.us> > Signed-off-by: Cong Wang <xiyou.wangc...@gmail.com> Applied.
