Subject: Re: [PATCH v2] sctp: Change defaults on cookie hmac selection

From: Neil Horman <>
Date: Fri, 14 Dec 2012 20:22:01 -0500

> Recently I posted commit 3c68198e75 which made selection of the cookie hmac
> algorithm selectable.  This is all well and good, but Linus noted that it
> changes the default config:
> I've modified the sctp Kconfig file to reflect the recommended way of making
> this choice, using the thermal driver example specified, and brought the
> defaults back into line with the way they were prior to my origional patch
> Also, on Linus' suggestion, re-adding ability to select default 'none' hmac
> algorithm, so we don't needlessly bloat the kernel by forcing a non-none
> default.  This also led me to note that we won't honor the default none
> condition properly because of how sctp_net_init is encoded.  Fix that up as
> well.
> Tested by myself (allbeit fairly quickly).  All configuration combinations seems
> to work soundly.
