sctp: fix some type cast warnings introduced since very beginning

2017-10-29T09:03:24+00:00

These warnings were found by running 'make C=2 M=net/sctp/'.
They are there since very beginning.

Note after this patch, there still one warning left in
sctp_outq_flush():
  sctp_chunk_fail(chunk, SCTP_ERROR_INV_STRM)

Since it has been moved to sctp_stream_outq_migrate on net-next,
to avoid the extra job when merging net-next to net, I will post
the fix for it after the merging is done.

sctp: Add peeloff-flags socket option

2017-07-01T22:26:11+00:00

Based on a request raised on the sctp devel list, there is a need to
augment the sctp_peeloff operation while specifying the O_CLOEXEC and
O_NONBLOCK flags (simmilar to the socket syscall).  Since modifying the
SCTP_SOCKOPT_PEELOFF socket option would break user space ABI for existing
programs, this patch creates a new socket option
SCTP_SOCKOPT_PEELOFF_FLAGS, which accepts a third flags parameter to
allow atomic assignment of the socket descriptor flags.

Tested successfully by myself and the requestor

sctp: add SCTP_PR_STREAM_STATUS sockopt for prsctp

2017-04-03T21:52:35+00:00

Before when implementing sctp prsctp, SCTP_PR_STREAM_STATUS wasn't
added, as it needs to save abandoned_(un)sent for every stream.

After sctp stream reconf is added in sctp, assoc has structure
sctp_stream_out to save per stream info.

This patch is to add SCTP_PR_STREAM_STATUS by putting the prsctp
per stream statistics into sctp_stream_out.

v1->v2:
  fix an indent issue.

sctp: add get and set sockopt for reconf_enable

2017-03-13T06:22:24+00:00

This patchset is to add SCTP_RECONFIG_SUPPORTED sockopt, it would
set and get asoc reconf_enable value when asoc_id is set, or it
would set and get ep reconf_enalbe value if asoc_id is 0.

It is also to add sysctl interface for users to set the default
value for reconf_enable.

After this patch, stream reconf will work.
