[PATCH] net: openvswitch: datapath: fix data type in queue_gso_packets

gso_type is being used in binary AND operations together with SKB_GSO_UDP. The issue is that variable gso_type is of type unsigned short and SKB_GSO_UDP expands to more than 16 bits: SKB_GSO_UDP = 1 << 16 this makes any binary AND operation between gso_type and SKB_GSO_UDP to be always zero,

[PATCH net 4/5] sctp: avoid flushing unsent queue when doing asoc reset

Now when doing asoc reset, it cleans up sacked and abandoned queues by calling sctp_outq_free where it also cleans up unsent, retransmit and transmitted queues. It's safe for the sender of response, as these 3 queues are empty at that time. But when the receiver of response is doing the reset,

[PATCH net 5/5] sctp: set sender next_tsn for the old result with ctsn_ack_point plus 1

[PATCH net 3/5] sctp: only allow the asoc reset when the asoc outq is empty

As it says in rfc6525#section5.1.4, before sending the request, C2: The sender has either no outstanding TSNs or considers all outstanding TSNs abandoned. Prior to this patch, it tried to consider all outstanding TSNs abandoned by dropping all chunks in all outqs with sctp_outq_free

[PATCH net 2/5] sctp: only allow the out stream reset when the stream outq is empty

Now the out stream reset in sctp stream reconf could be done even if the stream outq is not empty. It means that users can not be sure since which msg the new ssn will be used. To make this more synchronous, it shouldn't allow to do out stream reset until these chunks in unsent outq all are sent

[PATCH net 3/3] sctp: do not abandon the other frags in unsent outq if one msg has outstanding frags

Now for the abandoned chunks in unsent outq, it would just free the chunks. Because no tsn is assigned to them yet, there's no need to send fwd tsn to peer, unlike for the abandoned chunks in sent outq. The problem is when parts of the msg have been sent and the other frags are still in unsent

[PATCH net 1/3] sctp: only update outstanding_bytes for transmitted queue when doing prsctp_prune

Now outstanding_bytes is only increased when appending chunks into one packet and sending it at 1st time, while decreased when it is about to move into retransmit queue. It means outstanding_bytes value is already decreased for all chunks in retransmit queue. However sctp_prsctp_prune_sent is a

[PATCH net 2/3] sctp: abandon the whole msg if one part of a fragmented message is abandoned

As rfc3758#section-3.1 demands: A3) When a TSN is "abandoned", if it is part of a fragmented message, all other TSN's within that fragmented message MUST be abandoned at the same time. Besides, if it couldn't handle this, the rest frags would never get assembled in peer side.

[PATCH net 0/3] a couple of fixes for chunks abandoned in prsctp

Now when abandoning chunks in prsctp, it doesn't consider for frags in one msg, which would cause peer can never receive the whole frags for one msg to get them reassembled, these pieces of this msg will stay in the reasm queue forever and block the following chunks' receiving. This patchset is
