Not necessarily. A RedHat binary rpm is based on a tar.gz, which is
included in the source rpm along with any patches RedHat applied to it
before doing the make. The will make changes they think will improve
security, make sure it will run with glibc, or just fix code they think
is wrong, or adjust the placement of files and paths, or make it easier
to debug, or even (when times are slack) just to fix compiler warnings.
I don't think there is anything wrong or sneaky about that. They
distribute software under their own name, as it were, and they want to
make it as good as they know how to. I don't always use their patches,
but I don't throw them away without looking at them either.
Maybe they didn't patch ipfwadm. If you want to know for sure, get the
source rpm and take a look.
