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)

dholland 39ab77f3dd Silence -Wpointer-sign on crypt-sha1.c. 
This requires casts, which is not entirely desirable; however, this way
at least no *more* pointer sign issues can creep in.

Output object files are unchanged on amd64.
 2013-08-10 18:42:29 +00:00
riastradh 82db4b9858 Replace consttime_bcmp/explicit_bzero by consttime_memequal/explicit_memset. 
consttime_memequal is the same as the old consttime_bcmp.
explicit_memset is to memset as explicit_bzero was to bcmp.

Passes amd64 release and i386/ALL, but I'm sure I missed some spots,
so please let me know.
 2013-06-24 04:21:19 +00:00
drochner 8588929dc5 Add "consttime_bcmp" and "explicit_bzero" functions for both kernel 
abd userland, as proposed on tech-security, with explicit_bzero using
a volatile function pointer as suggested by Alan Barrett.
Both do what the name says. For userland, both are prefixed by "__"
to keep them out of the user namespace.
Change some memset/memcmp uses to the new functions where it makes
sense -- these are just some examples, more to come.

christos 0d2c1e1b4f - go back to returning NULL, we are going to wrap crypt instead. 
- limit length of key to 253 to prevent truncation.

christos 671f563b75 we want to check against "*0" not "*\0" 2011-12-27 22:01:26 +00:00
christos 91160c96e4 Instead of returning ":" on error, return "*0" or "*1" which will always result 
in logged password entries, even if the calling program decides to blindly
use them. Discussed in: http://www.openwall.com/lists/oss-security/2011/11/15/3

drochner ccdea5df98 -fix maximum length of salt (missing prefix, rounding error) 
-clip number of rounds at 31 -- this is log2 of the real number,
 and anything larger would break exponentation

 salt prefix
