riastradh 3db7caeeb3 Comment on possible data-dependent branch in `!res'. 2013-08-28 19:31:14 +00:00
riastradh 1239c2bb08 Publish explicit_memset and consttime_memequal in userland libc. 
Remove the double-underscore from the userland versions, and do the
weak alias dance instead, now that these are public parts of libc.

As discussed on tech-userlevel:

https://mail-index.netbsd.org/tech-userlevel/2013/06/24/msg007843.html
(option 3)
 2013-08-28 17:47:07 +00:00
riastradh 495fdb7e9a Make explicit_memset match memset's return value. 2013-08-28 15:46:23 +00:00
riastradh cc79193075 Fix sense of consttime_memequal and update all callers. 
Now it returns true (nonzero) to mean equal and false (zero) to mean
inequal, as the name suggests.
