When I review ocfs2 code, find there are 2 typos to "successfull". After
doing grep "successfull " in kernel tree, 22 typos found totally -- great
minds always think alike :)
This patch fixes all the similar typos. Thanks for Randy's ack and comments.

The number of identifiers needs to be checked against the option
length. Also, the identifier index provided needs to be verified
to make sure that it doesn't exceed the bounds of the array.

The structure used for SCTP_AUTH_KEY option contains a
length that needs to be verfied to prevent buffer overflow
conditions. Spoted by Eugene Teo <eteo@redhat.com>.

The new SCTP socket api (draft 16) updates the AUTH API structures.
We never exported these since we knew they would change.
Update the rest to match the draft.

I was notified by Randy Stewart that lksctp claims to be
"the reference implementation". First of all, "the
refrence implementation" was the original implementation
of SCTP in usersapce written ty Randy and a few others.
Second, after looking at the definiton of 'reference implementation',
we don't really meet the requirements.

If SCTP-AUTH is enabled, received AUTH chunk with BAD shared key
identifier will cause kernel panic.
Test as following:
step1: enabled /proc/sys/net/sctp/auth_enable
step 2: connect to SCTP server with auth capable. Association is
established between endpoints. Then send a AUTH chunk with a bad
shareid, SCTP server will kernel panic after received that AUTH chunk.
SCTP client SCTP server
INIT ---------->
(with auth capable)
<---------- INIT-ACK
(with auth capable)
COOKIE-ECHO ---------->
<---------- COOKIE-ACK
AUTH ---------->
AUTH chunk is like this:
AUTH chunk
Chunk type: AUTH (15)
Chunk flags: 0x00
Chunk length: 28
Shared key identifier: 10
HMAC identifier: SHA-1 (1)
HMAC: 0000000000000000000000000000000000000000
The assignment of NULL to key can safely be removed, since key_for_each
(which is just list_for_each_entry under the covers does an initial
assignment to key anyway).
If the endpoint_shared_keys list is empty, or if the key_id being
requested does not exist, the function as it currently stands returns
the actuall list_head (in this case endpoint_shared_keys. Since that
list_head isn't surrounded by an actuall data structure, the last
iteration through list_for_each_entry will do a container_of on key, and
we wind up returning a bogus pointer, instead of NULL, as we should.

SCTP-AUTH requires selection of CRYPTO, HMAC and SHA1 since
SHA1 is a MUST requirement for AUTH. We also support SHA256,
but that's optional, so fix the code to treat it as such.

In the case where no autheticated chunks were specified, we were still
trying to verify that a given chunk needs authentication and doing so
incorrectly. Add a check for parameter length to make sure we don't
try to use an empty auth_chunks parameter to verify against.

Most drivers need to set length and offset as well, so may as well fold
those three lines into one.
Add sg_assign_page() for those two locations that only needed to set
the page, where the offset/length is set outside of the function context.

Add SCTP-AUTH API. The API implemented here was
agreed to between implementors at the 9th SCTP Interop.
It will be documented in the next revision of the
SCTP socket API spec.
