2.4.23 tux kernel patch?

I saw a report about a security issue in the 2.4.22 (and earlier) kernel.

So, I started going through the process of upgrading my kernel (which I 
usually build from source).  But, I need a tux patch for it.

http://people.redhat.com/~mingo/TUX-patches/

contains patches for 2.4.17 and 2.4.18 only.

In the past, someone on this list provided a:

tux2-full-2.4.21-rc1-final-A3 patch, and it worked great (I'm at 2.4.21 now).

This seems like a continuing problem for me.  Is there a better way to do this?

I am a Redhat 9 subscriber, but I have been building my own kernels (old 
habit, I guess).  This has gotten me into trouble before as well (RH has 
had bugs associated with people using their own kernel).  But, RH is also 
not continuing support past spring 2004, and I'm too poor to afford their 
enterprise product...  whine whine

Anyway... what are other tux users on this list doing about kernel updates?

Re: 2.4.23 tux kernel patch?

actually, there is this file :

http://people.redhat.com/~mingo/TUX-patches/tux2-2.4.22-A0

maybe it would work for you 

i use the stock redhat kernel that they supply, on rh 7.3. actually, the
patch for the security issue is small, you could apply it to your current
kernel. 

--- linux-2.4.20/mm/mmap.c~     
+++ linux-2.4.20/mm/mmap.c      
 <at>  <at>  -1059,6 +1059,9  <at>  <at> 
        if (!len)
                return addr;

+       if ((addr + len) > TASK_SIZE || (addr + len) < addr)
+               return -EINVAL;
+
        /*
         * mlock MCL_FUTURE?
         */

this way you can use kernel 2.4.22, and patch it with the patches above (tux
and do_brk). maybe the 2.4.22 tux patch will work with 2.4.23.

i usually analize the redhat kernel srpms for changes before i use them
after such bugfixes, so this was clearly visible to me that the patch is
trivial.

tux + grsecurity + kernel 2.4.23 patch

Hi,

for everyone interested I've combined tux2-2.4.22-A0 with grsecurity 
1.9.13 for patching kernel 2.4.23:

    
http://rotanovs.com/linux/grsecurity-1.9.13-tux2-2.4.22-A0-2.4.23.patch.bz2

Tested on 3 servers so far, please let me know if you experience any 
problems.

Best Wishes,
Viktors

Fedora and Tux

Hi,

What's the state of play regarding Fedora and Tux? I read something about 
Fedora dropping tux in favour of Apache, and the kernel doesn't seem to have 
Tux built in, yet FC1 ships with a Tux RPM.

I managed to get Tux working by patching the FC1 kernel with 
http://people.redhat.com/~mingo/TUX-patches/tux2-2.4.22-A0 and tweaking until 
it built, and then using RH9's Tux RPM. It isn't very attractive though.

On a different note, the list search at 
https://www.redhat.com/archives/tux-list/ doesn't seem to work here ("Can't 
open template file '/etc/mnogosearch/search.htm'!")

Finally, does anyone know of any "Powered By Tux" icons?

Cheers,

Luke

Tux's future?

hi all

how does Tux's future look when 2.6 is out?
Is it to be ported, or should it be regarded dead?

[patch] tux3-2.4.23-A1

i've merged the latest Tux bits to 2.4.23:

	redhat.com/~mingo/TUX-patches/tux3-2.4.23-A1

the user module protocol version increased to 3, due to 64-bitness
cleanups in the API. Various other fixes were merged as well. If you are
using modules then you'll need an updated userspace package as well:

	redhat.com/~mingo/TUX-patches/tux-3.2.15.tar.gz

let me know if there are any regressions.

[patch] tux3-2.6.0-C3


i've ported Tux to 2.6.0. A test release can be found at:

 	redhat.com/~mingo/TUX-patches/tux3-2.6.0-C3

functionality-wise this version has all the latest features and fixes.
(it's equivalent to tux3-2.4.23-A1) It needs the latest userspace
package:

 	redhat.com/~mingo/TUX-patches/tux-3.2.15.tar.gz

i've tested it with simple workloads and modules, and fixed all obvious
problems, but this 2.6 Tux port is otherwise quite fresh, so be careful. 
It has no known regressions at the moment.

hmm I'm having a bit of trouble applying the patch to 2.6.0-mm1 -

I had 3 rejects which I fixed by hand, but during the kernel compile I 
got this: (any words of wisdom?)

...

net/built-in.o(.text+0x308b): In function `sys_tux':
