sctp: remove the typedef sctp_hmac_algo_param_t

2017-07-17T03:52:14Z

This patch is to remove the typedef sctp_hmac_algo_param_t, and replace with struct sctp_hmac_algo_param in the places where it's using this typedef. It is also to use sizeof(variable) instead of sizeof(type). Signed-off-by: Xin Long Signed-off-by: David S. Miller

net, sctp: convert sctp_auth_bytes.refcnt from atomic_t to refcount_t

2017-07-04T21:35:18Z

refcount_t type and corresponding API should be used instead of atomic_t when the variable is used as a reference counter. This allows to avoid accidental refcounter overflows that might lead to use-after-free situations.

This patch is to remove the typedef sctp_paramhdr_t, and replace with struct sctp_paramhdr in the places where it's using this typedef. It is also to fix some indents and use sizeof(variable) instead of sizeof(type). Signed-off-by: Xin Long Signed-off-by: David S. Miller

sctp: remove the typedef sctp_cid_t

sctp: use IS_ENABLED() instead of checking for built-in or module

2016-09-11T04:19:11Z

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either built-in or as a module, use that macro instead of open coding the same. Using the macro makes the code more readable by helping abstract away some of the Kconfig built-in and module enable details.

sctp: translate host order to network order when setting a hmacid

2015-11-15T23:27:27Z

now sctp auth cannot work well when setting a hmacid manually, which is caused by that we didn't use the network order for hmacid, so fix it by adding the transformation in sctp_auth_ep_set_hmacs. even we set hmacid with the network order in userspace, it still can't work, because of this condition in sctp_auth_ep_set_hmacs(): if (id > SCTP_AUTH_HMAC_ID_MAX) return -EOPNOTSUPP; so this wasn't working before and thus it won't break compatibility.

sctp: allow authenticating DATA chunks that are bundled with COOKIE_ECHO

2015-06-12T21:18:20Z

Currently, we can ask to authenticate DATA chunks and we can send DATA chunks on the same packet as COOKIE_ECHO, but if you try to combine both, the DATA chunk will be sent unauthenticated and peer won't accept it, leading to a communication failure. This happens because even though the data was queued after it was requested to authenticate DATA chunks, it was also queued before we could know that remote peer can handle authenticating, so sctp_auth_send_cid() returns false. The fix is whenever we set up an active key, re-check send queue for chunks that now should be authenticated. As a result, such packet will now contain COOKIE_ECHO + AUTH + DATA chunks, in that order.
