2019-02-27netfilter: nft_compat: use .release_ops and remove list of extensionPablo Neira Ayuso
Add .release_ops, that is called in case of error at a later stage in the expression initialization path, ie. .select_ops() has been already set up operations and that needs to be undone. This allows us to unwind .select_ops from the error path, ie. release the dynamic operations for this extension. Moreover, allocate one single operation instead of recycling them, this comes at the cost of consuming a bit more memory per rule, but it simplifies the infrastructure.

2019-02-24tls: Return type of non-data records retrieved using MSG_PEEK in recvmsgVakul Garg
The patch enables returning 'type' in msghdr for records that are retrieved with MSG_PEEK in recvmsg. Further it prevents records peeked from socket from getting clubbed with any other record of different type when records are subsequently dequeued from strparser. For each record, we now retain its type in sk_buff's control buffer cb[]. Inside control buffer, record's full length and offset are already stored by strparser in 'struct strp_msg'. We store record type after 'struct strp_msg' inside 'struct tls_msg'. For tls1.2, the type is stored just after record dequeue. For tls1.3, the type is stored after record has been decrypted. Inside process_rx_list(), before processing a non-data record, we check that we must be able to return back the record type to the user application. If not, the decrypted records in tls context's rx_list is left there without consuming any data.

2019-02-17devlink: add flash update commandJakub Kicinski
Add devlink flash update command. Advanced NICs have firmware stored in flash and often cryptographically secured. Updating that flash is handled by management firmware. Ethtool has a flash update command which served us well, however, it has two shortcomings: - it takes rtnl_lock unnecessarily - really flash update has nothing to do with networking, so using a networking device as a handle is suboptimal, which leads us to the second one: - it requires a functioning netdev - in case device enters an error state and can't spawn a netdev (e.g. communication with the device fails) there is no netdev to use as a handle for flashing. Devlink already has the ability to report the firmware versions, now with the ability to update the firmware/flash we will be able to recover devices in bad state. To enable updates of sub-components of the FW allow passing component name. This name should correspond to one of the versions reported in devlink info. v1: - replace target id with component name (Jiri).

The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU.

2019-02-13flow_offload: fix block statsJohn Hurley
With the introduction of flow_stats_update(), drivers now update the stats fields of the passed tc_cls_flower_offload struct, rather than call tcf_exts_stats_update() directly to update the stats of offloaded TC flower rules. However, if multiple qdiscs are registered to a TC shared block and a flower rule is applied, then, when getting stats for the rule, multiple callbacks may be made. Take this into consideration by modifying flow_stats_update to gather the stats from all callbacks. Currently, the values in tc_cls_flower_offload only account for the last stats callback in the list.
