Back in March, there was some discussion about ratelimiting the
BSDCOMPAT errors, and James Morris provided a patch to achieve
this.
http://www.ussg.iu.edu/hypermail/linux/kernel/0303.3/1078.html
To which David Miller stated the patch had been applied.

Unfortunately, it seems to have fallen through the cracks. Below
is the patch again, updated for 2.6.0-test3 - please apply.

Umm.. am I dense, or does this only warn once for *the first program*
to do it after the system boots? And you don't get another warning about
any OTHER programs until you reboot in a few weeks (possibly)?
If so, why are we bothering at all? Once *per process* I could see, but
once per boot?

Yes, this patch does suck hard.
I see no reason to apply this, just fix your apps and the
warning will stop. There's only a handful of programs
that trigger this at all.

Unfortunately Red Hat's BIND is among the more prominent. :-/

Once per process is too complicated, and an aggregate of people reporting
the message should lead to all of the major apps being fixed.

Sorry, I didn't mean to imply _just_ Red Hat. Probably all distros'
BINDs use SO_BSDCOMPAT. What I meant was this is the only program I
notice the warning from, when running a 2.5 kernel on an otherwise Red
Hat 9 system. And it comes up every time I connect to the net, when I
restart named with new forwarders, which is about hourly :/

Admittedly, recompiling Bind after commenting out the #define from
asm/socket.h does also solve the errors. But it does seem overkill
to warn on every single use of this...
