The version of the fs_locations fixes are slightly older than my most
recent. Looking back through the archive, I think it may have been my
mistake. Sorry!
There's a missing patch from Chuck that makes the ip address parsing a
bit more paranoid. I'll resend that, followed by the newer versions of
the other patches.
Aside from the missing patch from Chuck, the only difference between the
versions you have and my latest are summarized below. it's just:
- a cosmetic change to set_port to address your complaints about
blocks used just to define local variables, and
- changes to stop bothering to check for scope id's in v6
addresses.
So--could you just take the following patches, and throw out the 4
corresponding patches from me in your current tree?
