06:57 < sachin> I was working with 2.5.73 and couple of days back switched to 2.5.75. It is not behaving well and crashing before even booting up.
06:58 < sachin> I thought I could use usermodelinux to help me diagnose the problem. Can somebody tell me any pointer to read about howto write patch for 2.5.75 since the latest patch available for download is for 2.5.70

12:03 < LowV> i've applied the ska's patch(host-skas3.ptrace.patch) to the host-kernel (2.4.21). patch gave no errors. Make bzImage gives : undefined reference to `proc_mm_get_mm'  Any hints ?
12:07 < desaster> did you do make dep clean
12:08 < desaster> did you enable /proc/mm in configure
12:08 < desaster> (just guessing)
12:08 < LowV> found the proc/mm thing in the archives 
12:09 < LowV> was already trying again
12:09 < LowV> thnx
12:23 < attriel> hey, is there a skas patch for 2.5 ?  i don't find the proc/mm stuff anywhere to turn on, os I presume I need the patch, but the one i see is for 2.4 :/  do i need to try an' roll-my-own or is it builtin or just hiding somewhere I'm not thinking to look ?

14:03 < pirlouit> hello
14:03 < pirlouit> is there a way to specify the speed of the network interfaces in UML ?
14:04 < pirlouit> or is it going as fast as the resources allow you to go
14:07 < AquaJo> as fast as possible
14:08 < attriel> why would you want to limit it, anyway ?
14:09 -!- ticallion [~ticallion@213.175.160.110] has joined #uml
14:09 < BB> why not ;)
14:09 < attriel> heh, i s'pose there is that :o
14:10 < attriel> can you limit interface speeds on the bare kernel?  I've never really tried :o
14:10 < BB> well you could limit it on the host side
14:14 < BB> rar now our clara is down

14:18 < pflanze> Hello
14:19 < ticallion> pflanze: :)
14:19 < pflanze> I'm trying to compile 2.6.0-test1 with ARCH=uml, but I'm getting:
14:19 < pflanze> include/asm/processor.h:66: `CONFIG_X86_L1_CACHE_SHIFT' undeclared here (not in a function)
14:19 < pflanze> (ARCH=um that is)
14:19 < pflanze> any idea?
14:20 < ticallion> interesting, I'm having a different error at the start of the compilation, how did u get that far?! did u patch 2.6-test1 or u using it as is?!
14:20 < pflanze> just right from kerenl.org
14:20 < pflanze> no patches.
14:21 < caker> i think what's included in 2.6 is way old
14:21 < ticallion> well umm, can't offer any help but word is the uml code in 2.6-test1 is very old
14:21 < pflanze> I did 'make xconfig ARCH=um' then 'make ARCH=um'
14:21 < pflanze> huh
14:22 < pflanze> Time to hurry up and get new stuff in?
14:22 < ticallion> anyway, why the hell did they include it if it doesn't build even, I haven't heard from anybody who successfully built it
14:22 < pflanze> ok so I'll have to get a patch to remove current uml code and put current in.
14:22 < pflanze> (how weird..:)
14:24 < ticallion> there isn't a uml patch that applies to that release unfortunately, we're all waiting on it
14:25 < pflanze> IC
14:26 < pflanze> This means that kernel developers don't use UML for testing kernels.
14:26 < ticallion> heh... good one
14:29 < pflanze> Is there any 2.5.x kernel working well as uml kernel?
14:30 < attriel> yah, i asked about 2.6 yesterday; the UML in 2.6 is out of date and "absolutely doesn't work" :o
14:31 < attriel> i can get the 2.5.70 to compile with the UML patch, but I can't get it to run (b/c apparently the SKAS stuff isn't in and i couldn't find a 2.5 patch for it ... os i'm trying to roll my own :o)
14:32 < caker> attriel: if you run a 2.4 host kernel with the skas patch, won't a 2.5 UML kernel use skas?
14:34 < attriel> dunno, haven't tried that yet
14:34 < ticallion> caker: right, skas is only a host patch afaik and it's not even uml-specific
14:34 < attriel> my 'patching'' apparently completely blowing out the compile process, maybe i'll try that next ;)
14:35 < attriel> a few too many things changed from 2.4.20 to 2.5.70 to make the patching "clean" :/
14:36 < ticallion> attriel: there r 2.5 uml patches around if I remember correctly
14:37 < attriel> yah, the UML ones but i couldn't get the UML to launch b/c it couldn't find the SKAS hooks and /proc/mm, but it won't even compile without the SKAS hooks (or at least on my box)
14:37 < attriel> er without SKAS enabled that last bit should say
14:38 < attriel> guess I'll back down to getting a 2.4 host+SKAS to launch 2.5UML so I can at least start messing with using it :o
14:42 < pflanze> kernel.usermodelinux.org does have a 2.5.69 binary and .config, but no 2.5.x patch.

14:44 < attriel> that's the UML though; and i know there's the 2.5.70 patch there somewhere, i downloaded it yesterday
14:44 < attriel> (now compiling a 2.4.21-skas host kernel to see if that gets me anywhere :o)

17:06 < pflanze> Sigh
17:07 < pflanze> I have patched a 2.4.21 with grsec then uml, resolved all conflicts I thought, but now I get:
17:07 < pflanze> /usr/src/UML/linux/include/asm/posix_types.h:4: asm/arch/posix_types.h: No such file or directory
17:07 < pflanze> and many more no such files.
17:08 < pflanze> what is the build command for uml, not  make ARCH=um ?
17:10 < pflanze> AAAh, make linux ARCH=um
17:11 < pflanze> (why are those makefiles only so strange)
17:21 < pflanze> ok compiles, but seems I forgot to enable grsec stuff at all.
17:22 < pflanze> Turns out that grsec is not enabled for um. ;)
17:22 < pflanze> How to change that?
17:22 < pflanze> Or has anyone done it already?
17:25 < pflanze> grsecurity/* was even compiled!! funny.
