Description Mark Andrews 2006-02-24 00:50:04 UTC
	We have incorporated the above revision into BIND 9.4.0. 

	Testing of the DS record with SHA256 (see draft) showed up a
	problem on sparc machines.  data is not always correctly aligned
	to be correctly cast to (sha2_word32*) / (sha2_word64*).

	http://www.ietf.org/internet-drafts/draft-ietf-dnsext-ds-sha256-05.txt

Fix: 

Always copy data to context->buffer before calling SHA256_Transform()
	as context->buffer is correctly aligned.

Responsible Changed
From-To: freebsd-bugs->jmg

I'll take over this bug...  I plan on replacing the sha256 in kernel 
w/ the faster one from userland in the near future...
