Re: Supporting linux-audit in our 2.6 kernel

A big one. The 2.6.6 kernel is missing a lot of the code needed by the planned 
implementation. You need to apply a lot of patches to get it close to the 
2.6.12 kernel's implementation. Offhand, I don't know how tricky that would 
be since we've been working with RHEL4 kernels.

Get the latest from rawhide. 0.6.9. 
http://mirrors.kernel.org/fedora/core/development/SRPMS/audit-0.6.9-1.src.rpm

Rawhide's version is much better. 0.5 doesn't even come close.

There's some docs in 0.6.9's package

You need patched userland utilities. For example, a new pam, at, 
glibc-kernheaders, shadow-utils, etc.

Yes. However, I don't think they will be available under RHEL3. Its all aimed 
at RHEL4.

0.6.9

With this short of a deadline, you might be better off trying it on Fedora 
Core 4 test 1 + rawhide updates. You can demonstrate some functionality with 
that setup, but we are still developing the filesystem auditing and a few 
other pieces. So, even rawhide is not a complete solution.

Hope this helps...
