We need to ensure the loads from the descriptor are done after the MMIO store clearing the interrupts has completed, otherwise we might still miss work. A read back from the MMIO register will "push" the posted store and ioread32 has a barrier on weakly aordered architectures that will order subsequent accesses. Signed-off-by:

Hopefully my understanding of how the hardware works is correct, as the documentation isn't completely clear. So far I have seen no obvious issue. Pause seem to also work with NC-SI. Signed-off-by:

A non-wired up implementation accidentally made its way in a previous patch (Make ring sizes configurable via ethtool). This removes it and wires up the generic phy_ethtool_nway_reset instead. Signed-off-by:

Xin Long says: ==================== sctp: add proper process for duplicated stream reconf requests Now sctp stream reconf will process a request again even if it's seqno is less than asoc->strreset_inseq. It may cause a replay attack. This patchset is to avoid it by add proper process for all duplicated stream reconf requests. ==================== Signed-off-by: -

This patch is to fix the replay attack issue for strreset asoc requests. When a duplicated strreset asoc request is received, reply it with bad seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with the result saved in asoc if it's seqno >= asoc->strreset_inseq - 2. But note that if the result saved in asoc is performed, the sender's next tsn and receiver's next tsn for the response chunk should be set. It's safe to get them from asoc. Because if it's changed, which means the peer has received the response already, the new response with wrong tsn won't be accepted by peer. Signed-off-by:

This patch is to fix the replay attack issue for strreset and addstrm in requests. When a duplicated strreset in or addstrm in request is received, reply it with bad seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with the result saved in asoc if it's seqno >= asoc->strreset_inseq - 2. For strreset in or addstrm in request, if the receiver side processes it successfully, a strreset out or addstrm out request(as a response for that request) will be sent back to peer. reconf_time will retransmit the out request even if it's lost. So when receiving a duplicated strreset in or addstrm in request and it's result was performed, it shouldn't reply this request, but drop it instead. Signed-off-by:

Now sctp stream reconf will process a request again even if it's seqno is less than asoc->strreset_inseq. If one request has been done successfully and some data chunks have been accepted and then a duplicated strreset out request comes, the streamin's ssn will be cleared. It will cause that stream will never receive chunks any more because of unsynchronized ssn. It allows a replay attack. A similar issue also exists when processing addstrm out requests. It will cause more extra streams being added. This patch is to fix it by saving the last 2 results into asoc. When a duplicated strreset out or addstrm out request is received, reply it with bad seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with the result saved in asoc if it's seqno >= asoc->strreset_inseq - 2. Note that it saves last 2 results instead of only last 1 result, because two requests can be sent together in one chunk. And note that when receiving a duplicated request, the receiver side will still reply it even if the peer has received the response. It's safe, As the response will be dropped by the peer.
