Compiling trouble

[Obscure]

Hi
Compiling grsec patch from Con Kolivas on my Slack 9.0 and 2.4.23 (http://www.plumlocosoft.com/kernel/patc ... 042057.bz2)
I got this error:

Maybe I'm on the wrong forum 'cause it's not a pure grsecurity patch but maybe someone could help..

this is normally a sign of 64 bit arithmetic, maybe the -ck patch redefines one of the types used in gr_acl_handle_psacct and triggers a 64 bit division, it's not a grsec problem per se, but such division has to be modified to call do_div().

i made this patch and submitted it to Con. Unfortunately i missed a variable rename in ckbase. There is a 1-line fix for it now (also on that url). Did you apply it?

[Obscure]

I've applied all the patches into ../kernel/patches/2.4/2.4.23/2.4.23-ck1/fixes/ :

2.4.23-ck1-grsecurity-fix.patch
patch-2.4.23-ck1-fix1

but the error still remains..

The problem is the 64 bit jiffies in -ck since 2.4.23.
An updated patch will be made available later today, i'm the one to blame for this low quality patch that was made in very little time and not tested well enough. I just merged the 2 and fixed the rejects, not paying attention to variables that might have changed types or names.
The new patch will fully compile and work, and once tested well enough submitted to Con, or the new 2.4 -ck maintainer, to replace the old one and the fix.
