dccp: Fix possible memleak in dccp_init and dccp_fini
[ Upstream commit c96b6acc ] There are some memory leaks in dccp_init() and dccp_fini(). In dccp_fini() and the error handling path in dccp_init(), free lhash2 is missing. Add inet_hashinfo2_free_mod() to do it. If inet_hashinfo2_init_mod() failed in dccp_init(), percpu_counter_destroy() should be called to destroy dccp_orphan_count. It need to goto out_free_percpu when inet_hashinfo2_init_mod() failed. Fixes: c92c81df ("net: dccp: fix kernel crash on module load") Reported-by:Hulk Robot <hulkci@huawei.com> Signed-off-by:
