Perhaps a USE flag could be created to enable the glibc patches, then a
emerge --newuse could recompile glibc and the problem apps (or
everything); maybe a mini-howto document would also be helpful.
I would certainly like an easy way to enable any "free" performance
boost I can get!
Something like USE=dangerous-amd64-hack? <g>
(Seriously, there at least used to be a local use flag
USE=frickin-big-security-hole, or some such, on some app I can't remember
at the moment. Turns out a teacher was using that app in his class as a
an example or something, so the dev left the ability to create it there,
but with a USE flag nobody in their right mind would normally enable. I
wish I could remember what it was, but grepping use.local.desc for
anything that might be related doesn't seem to bring it up. Perhaps the
app, or anyway the USE flag, has now been removed from portage?)
The use.local.desc description could point to the bug, which is IIRC what
the one above did, for those wanting more information about just why such
a USE flag exists, and just why someone might be persuaded to enable it.
Are you talking about GAPING_SECURITY_HOLE? If so, this flag is still
in use by the net-analyzer/netcat package. It enables the "-E" (iirc)
switch
which allows you to do something like:
nc -l -p 12345 -E /bin/bash
This(or something close to it) would cause netcat to listen on port 12345,
and forward the person who connects to it a nice bash shell.
