basically, what we are trying to do is getting either lids or grsec to
work with a 2418-hppa kernel.

the first steps were with "normal" lids, which bombed at early stage
(shortly after init mounted the rootfs, even with security=3D0)

then i tried to make grsecurity patch fit the hppa kernel (but without
deeper knowledge about the differences between i386 stacks and hppa
stack layout i cannot make any code redesign in the stack protector and
the like), the grsec patch did not even build, so i assume, i made a
little mistake somewhere or the patch is not "proposed" to build
platform-independent.
i guess, i will have to look through parisc mem mgmt and proc arch
documentation before i can continue to make the patch fit

current situation:
with some minor changes 2418-hppa-lsm-lids compiles clean, boots, but
the "modprobe lids" in the box gives the following:
drehmoos:/lib/modules/2.4.18-lsm/kernel/security/lids# modprobe lids

=2E.. dmesg output ...

break 0,0: pid=3D236 command=3D'modprobe'
modprobe (pid 236): Breakpoint (code 0)

after logging in via ssh and just trying to reinsert it a second time,
the module enters:
drehmoos:~# modprobe lids
drehmoos:~# lsmod
Module                  Size  Used by    Not tainted
lids                  500780   1  (initializing)

drehmoos:~# lidsadm -V
VIEW
open: No such file or directory
lidsadm: cannot open /proc/sys/lids/locks

drehmoos:~# ls /proc/sys/lids
ls: /proc/sys/lids: No such file or directory

looks like there is some exercise left to the reader :-)

anyway, i gotta go to work now, it is 7:30 in the morning in .de and my
boss is likely to kill me for being late :-)

bye, pappy
