2017-11-28sctp: set sender next_tsn for the old result with ctsn_ack_point plus 1Xin Long
When doing asoc reset, if the sender of the response has already sent some chunk and increased asoc->next_tsn before the duplicate request comes, the response will use the old result with an incorrect sender next_tsn. Better than asoc->next_tsn, asoc->ctsn_ack_point can't be changed after the sender of the response has performed the asoc reset and before the peer has confirmed it, and it's value is still asoc->next_tsn original value minus 1. This patch sets sender next_tsn for the old result with ctsn_ack_point plus 1 when processing the duplicate request, to make sure the sender next_tsn value peer gets will be always right.

2017-11-28sctp: avoid flushing unsent queue when doing asoc resetXin Long
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, the users may already enqueue some chunks into unsent during the time waiting the response, and these chunks should not be flushed. To void the chunks in it would be removed, it moves the queue into a temp list, then gets it back after sctp_outq_free is done. The patch also fixes some incorrect comments in sctp_process_strreset_tsnreq.

2017-11-28sctp: only allow the asoc reset when the asoc outq is emptyXin Long
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 (even including sacked, retransmit and transmitted queues) when doing this reset, which is too aggressive. To make it work gently, this patch will only allow the asoc reset when the sender has no outstanding TSNs by checking if unsent, transmitted and retransmit are all empty with sctp_outq_is_empty before sending and processing the request.

2017-11-28sctp: only allow the out stream reset when the stream outq is emptyXin Long
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 out. This patch checks the corresponding stream outqs when sending and processing the request . If any of them has unsent chunks in outq, it will return -EAGAIN instead or send SCTP_STRRESET_IN_PROGRESS back to the sender.

2017-11-27ARM: avoid faulting on qemuRussell King
When qemu starts a kernel in a bare environment, the default SCR has the AW and FW bits clear, which means that the kernel can't modify the PSR A or PSR F bits, and means that FIQs and imprecise aborts are always masked. When running uboot under qemu, the AW and FW SCR bits are set, and the kernel functions normally - and this is how real hardware behaves. Fix this for qemu by ignoring the FIQ bit.
