data logging and kernel 2.4.20

data logging and kernel 2.4.20

[Francisco Javier Cabello Torres]

Hello,
I would like to use data logging feature on a 2.4.20-vanilla kernel. 

I have tried patches from SUSE and everything goes ok.

ftp://ftp.suse.com/pub/people/mason/patches/data-logging/2.4.20/

The problem is that until now, I was using patches from this url:

ftp://ftp.namesys.com/pub/reiserfs-for-2.4/2.4.20-pending

in order to fix known bugs. I have tried to apply both set of patches, but I 
get a lot of conflicts. Should I apply fix patches with suse data logging 
patches or suse patch include all of them?

Thanks in advance.

Franciso J. Cabello

I'd not suggest to use these, those patches are really old and are likely to 
have bugs.
Use ftp://ftp.suse.com/pub/people/mason/patches/data-logging/2.4.25/
and a kernel >= 2.4.25 with them.
I have them running on several production systems with a 2.4.26 kernel.

do Suse patches include reiserfs bug fixes?

As far I know the patches for 2.4.xx have not been updated with later bug 
fixes.
Namesys recommends a kernel >= 2.4.24 for reiserfs use.
See http://www.namesys.com/download.html

The data logging patches have been developed along the 2.4.xx
kernel series and the ones for 2.4.25 are the latest and the most stable.

I don't know if these patches work with 2.4.27-rc3, they may interfere with 
a bug fix for mounting reiserfs on Out-Of-Memory conditions.
I can confirm that these patches work reliable on 2.4.26.
(At least on the two intel servers it's used on.)

If I were you I would not use an old kernel like 2.4.20 that has MANY security
holes, especially because you are not bound to some vendor kernel like
red hat or suse.

You can try kernel 2.6.7, too. It comes with data=ordered + xattr/acl + quota 
support per default.
Later kernels than 2.6.7 may get a new block allocator that behaves better
in multiprocess situations and disk-barrier support.

Security exploits:

As you can see there are already new ones for 2.4.26, which are
only fixed in 2.4.27-rc3.

The patches do no harm on 2.4.26:
