i don't know exactly what you mean by fixed, but the ptrace fix was
backported all the way to the 2.2.x series (and i think to the 2.0.x as
well), as usual. 2.2's is 2.2.25.

i don't mean to come off as snarky or obnoxious, it's just that your
statement seemed unclear to me :).

btw, anyone know if PPC kernels have had the grsec patch apply cleanly
to mainline kernel.org source? as i use xfs fs, the patching is rather
extensive, and i haven't had much luck with it. i spent more than a week
trying to compile a grsec'd kernel, with freeswan (freeswan applied
clean, as did xfs except for one very minor .rej). as this is my server
box as well, until we can afford to get another machine, i need grsec to 
apply well :). i tried with debian kernel-source-2.4.20-*.deb as well;
no go.

though seeing from previous posts, the various issues i had are resolved, but
PAX_* anything on PPC is unusable (all i get is "this is unsupported on
this architecture"), and even with grsec turned off, i had problems
writing to /tmp, including startup scripts.

sorry for the long-winded possibly OT message O_O. 

cheers,
eric
