====================
sctp: add subscribe per asoc and sockopt SCTP_EVENT
This patchset mainly adds the Event Subscription sockopt described in
rfc6525#section-6.2:
"Subscribing to events as described in [RFC6458] uses a setsockopt()
call with the SCTP_EVENT socket option. This option takes the
following structure, which specifies the association, the event type
(using the same value found in the event type field), and an on/off
boolean.
struct sctp_event {
sctp_assoc_t se_assoc_id;
uint16_t se_type;
uint8_t se_on;
};
The user fills in the se_type field with the same value found in the
strreset_type field, i.e., SCTP_STREAM_RESET_EVENT. The user will
also fill in the se_assoc_id field with either the association to set
this event on (this field is ignored for one-to-one style sockets) or
one of the reserved constant values defined in [RFC6458]. Finally,
the se_on field is set with a 1 to enable the event or a 0 to disable
the event."
As for the old SCTP_EVENTS Option with struct sctp_event_subscribe,
it's being DEPRECATED.
v1->v2:
- fix some key word in changelog that triggerred the filters at
vger.kernel.org.
v2->v3:
- fix an array out of bounds noticed by Neil in patch 1/4.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
