kernel in parisc-linux CVS: binfmt_som.c:216:2: #error "Fix security hole before enabling me"
As I was trying the CVS kernel (using the exact same config that was previously uploaded around 2.4.18 as a config-712 to parisc-linux FTP), I ran ino the following error message: X8 binfmt_som.c:216:2: #error "Fix security hole before enabling me" make[3]: *** [binfmt_som.o] Error 1 make[3]: Leaving directory `/usr/src/linux-2.4/fs' make[2]: *** [first_rule] Error 2 make[2]: Leaving directory `/usr/src/linux-2.4/fs' make[1]: *** [_dir_fs] Error 2 make[1]: Leaving directory `/usr/src/linux-2.4' make: *** [stamp-build] Error 2 X8 Since I have not changed anything (except for adding PPP support), could this be caused by partial rewrites of some feature that currently breaks? Or what then? -- Martin-Éric Racine http://www.pp.fishpool.fi/~q-funk/

Make similar changes there as it makes to arch/i386/config.in. You'll probably need to port other changes from include/asm-i386 and arch/i386 too. It's a big job; more so for preempt than lowlat. But why not try 2.6? It's already got most of the lowlat stuff integrated and preempt needs someone to fix it in 2.6 too ;-) -- "It's not Hollywood.

RE: kernel building problems: low-latency and pre-emptive patches
Hi, Sorry first for bad presentation but I use a webmail interface which do it so badly. Interesting, can you let me know a url where to find patches (Con Kolivas?) That said, in general for such kernel patch there are parts platform specific and maintainer just test some of one :( So if you edit your patch file, you can read which files were changed and how. In the most simple case, just small changes in specific Config and/or Makefile could just be reproduce in parisc tree. But iirc here you will need more hack to make it works. hth, Joel > -- Original Message -- > Date: Fri, 26 Sep 2003 07:55:41 +0300 (EEST) > From: Martin-Éric Racine <[EMAIL PROTECTED]> > To: debian-hppa@lists.debian.org > Subject: kernel building problems: low-latency and pre-emptive patches > > > Greetings, Given how my HP712-60 is such a _SLOW_ machine, I thought I'd give a try to the low-latency and pre-emptive patches.

Anybody can shed a light as to why that is and how would I make them appear? Btw, this was using whatever kernel is currently in the parisc-linux CVS. Thanks!
