1. missing explicit includes for string.h, stdio.h, etc 2. missing explicit declaration for some common functions I have been unable to contact the upstream maintainer for this patch, http://www.inner.net/opie appears to be the source of truth but it unreachable

History:
|
|
|
|
Modified by cmetz for OPIE 2.32. Renamed mode to flags. Made flag
|
|
values symbolic constants. Added a flag for insecure override
|
|
support.
|
|
Modified by cmetz for OPIE 2.31. Removed active attack protection
|
|
support.
|
|
Modified by cmetz for OPIE 2.3. Split most of the function off
|
|
and turned this into a front-end for the new __opiewriterec().
|
|
Added code to compute the key from the secret. Use the opie_
|
|
prefix. Use new opieatob8() and opiebtoa8() return values.
|
|
Created by cmetz for OPIE 2.22.
