sctp: Don't advertise IPv4 addresses if ipv6only is set on the socket

2020-06-25T23:11:33Z

If a socket is set ipv6only, it will still send IPv4 addresses in the INIT and INIT_ACK packets. This potentially misleads the peer into using them, which then would cause association termination. The fix is to not add IPv4 addresses to ipv6only sockets.

net: Do not clear the sock TX queue in sk_set_socket()

2020-06-24T03:49:12Z

Clearing the sock TX queue in sk_set_socket() might cause unexpected out-of-order transmit when called from sock_orphan(), as outstanding packets can pick a different TX queue and bypass the ones already queued. This is undesired in general. More specifically, it breaks the in-order scheduling property guarantee for device-offloaded TLS sockets. Remove the call to sk_tx_queue_clear() in sk_set_socket(), and add it explicitly only where needed.

net: flow_offload: fix flow_indr_dev_unregister path

2020-06-20T03:12:58Z

If the representor is removed, then identify the indirect flow_blocks that need to be removed by the release callback and the port representor structure. To identify the port representor structure, a new indr.cb_priv field needs to be introduced. The flow_block also needs to be removed from the driver list from the cleanup path.

netfilter: flowtable: Make nf_flow_table_offload_add/del_cb inline

2020-06-16T01:06:52Z

Currently, nf_flow_table_offload_add/del_cb are exported by nf_flow_table module, therefore modules using them will have hard-dependency on nf_flow_table and will require loading it all the time. This can lead to an unnecessary overhead on systems that do not use this API. To relax the hard-dependency between the modules, we unexport these functions and make them static inline.

Currently, tcf_ct_flow_table_restore_skb is exported by act_ct module, therefore modules using it will have hard-dependency on act_ct and will require loading it all the time.
