If the fix is going to ship in 7.0 and hasn't yet been MFC'd, that needs to 
happen ASAP.  Could someone forward the patch/etc over to re@ for approval?

The procedure for doing an errata patch is basically that whoever is proposing 
the errata patch needs to e-mail a patch, or multiple patches if it's 
different for different branches, a proposed branch list, and as much of a 
completed errata notice template as possible (impact, etc) to re@ for review. 
Once re@ is OK that it's ready to go, it will get sent over to secteam@ to be 
put into production, binary updates generated, etc.  If in doubt about which 
branches, drop e-mail to secteam@ to ask which are supported, etc.

At this point we would probably not advise doing the errata patch before 7.0 
is released, so priority should go to preparing any patches that need to go 
out with 7.0.
