ospfd - always check config file permissions

[Martin Pelikan]

Hello,
this patch makes ospfd(8) and ospf6d(8) check its config file permissions
even if run with a -n to test it. bgpd already behaves this way (changed
6 years ago by henning@) and it's quite handy to fix the permissions while
doing tests, rather than at the first production boot time :-)
Any comments?

Appart from my desire to kill the permission checking?
I don't see why bgpd and ospfd needs this non-unix like behaviour, 
other tools like pfctl do not care. We install the file with the correct
permissions so if somebody changes them it is his fault. But this is just
my opinion.

Personally, I don't really care about the check. I saw bgpd notify me,
so I fixed that and then both ospfd's told me they were OK. Obviously
the errors followed next boot.
I'd just want the behavior to be consistent and the information
configuration OK to keep its meaning up. Because I found in CVS log
that Henning and Theo were discussing that earlier, I did it this way.
After all, it doesn't look like an expensive check, or is it?

Workaround for data corruption issue with ALI M5229 IDE chip used with Sun Blade 100/Netra X1.

[Brad]

The following diff is ported from NetBSD (the workaround originated from
OpenSolaris) to workaround the issue of data corruption with the ALI M5229
IDE chipset when using UltraDMA. Same workaround is also used by FreeBSD/Linux.
This chipset is found in some sparc64 systems such as the Blade 100 and
Netra X1.

I don't have any such systems but I went digging for this being curious
why the nasty hack was added to the kernel configs to disable UltraDMA
to workaround this bug and thus penalizing other IDE/SATA controllers
that could be in the same system. If you have one of the mentioned
systems please test this.
