sctp: add support for generating stream reconf resp chunk

2017-02-19T23:17:59+00:00

This patch is to define Re-configuration Response Parameter described
in rfc6525 section 4.4. As optional fields are only for SSN/TSN Reset
Request Parameter, it uses another function to make that.

sctp: drop unnecessary __packed from some stream reconf structures

2017-02-09T21:57:38+00:00

commit 85c727b59483 ("sctp: drop __packed from almost all SCTP structures")
has removed __packed from almost all SCTP structures. But there still are
three structures where it should be dropped.

This patch is to remove it from some stream reconf structures.

sctp: drop __packed from almost all SCTP structures

2017-02-07T19:11:04+00:00

__packed is considered harmful as it potentially generates code that
doesn't perform well and its usage should be avoided as much as
possible.

This patch drops __packed from all SCTP structures except one, which is
sctp_signed_cookie. In there it's required, as per changelog on
commit 9834a2bb4970 ("[SCTP]: Fix sctp_cookie alignment in the packet.").

After this patch, no alignment changes neither in x86 or x86_64 and
no exceptions were noticed during testing on both archs.

Code size for SCTP module also didn't change with this patch.

sctp: add support for generating stream reconf ssn reset request chunk

2017-01-18T19:55:09+00:00

This patch is to add asoc strreset_outseq and strreset_inseq for
saving the reconf request sequence, initialize them when create
assoc and process init, and also to define Incoming and Outgoing
SSN Reset Request Parameter described in rfc6525 section 4.1 and
4.2, As they can be in one same chunk as section rfc6525 3.1-3
describes, it makes them in one function.

sctp: sctp_diag should dump sctp socket type

2016-05-31T18:59:06+00:00

Now we cannot distinguish that one sk is a udp or sctp style when
we use ss to dump sctp_info. it's necessary to dump it as well.

For sctp_diag, ss support is not officially available, thus there
are no official users of this yet, so we can add this field in the
middle of sctp_info without breaking user API.

v1->v2:
  - move 'sctpi_s_type' field to the end of struct sctp_info, so
    that it won't cause incompatibility with applications already
    built.
  - add __reserved3 in sctp_info to make sure sctp_info is 8-byte
    alignment.

sctp: add sctp_info dump api for sctp_diag

2016-04-15T21:29:35+00:00

sctp_diag will dump some important details of sctp's assoc or ep, we use
sctp_info to describe them,  sctp_get_sctp_info to get them, and export
it to sctp_diag.ko.

v2->v3:
- we will not use list_for_each_safe in sctp_get_sctp_info, cause
  all the callers of it will use lock_sock.

- fix the holes in struct sctp_info with __reserved* field.
  because sctp_diag is a new feature, and sctp_info is just for now,
  it may be changed in the future.

sctp: fix missing SCTP mailing list address update

2014-01-20T03:55:50+00:00

The commit 91705c61b5202 ("net: sctp: trivial: update mailing list
address") updated almost all the SCTP mailing list address from

	"lksctp-developers@lists.sourceforge.net"
to
	"linux-sctp@vger.kernel.org"

except for the one in include/linux/sctp.h file. Fix this way trivial
one so that all is updated.
