Now, when we sendmsg, we translate the ep to laddr by selecting the first element of the list, and then do a lookup for a transport. But sctp_hash_cmp() will compare it against asoc addr_list, which may be a subset of ep addr_list, meaning that this chosen laddr may not be there, and thus making it impossible to find the transport. So we fix it by using ep + paddr to lookup transports in hashtable. In sctp_hash_cmp, if .ep is set, we will check if this ep == asoc->ep, or we will do the laddr check. Fixes: d6c0256a ("sctp: add the rhashtable apis for sctp global transport hashtable") Signed-off-by:
