For the record, it affects rpm-4.8 & 4.9 too See http://rpm.org/gitweb?p=rpm.git;a=blob;f=scripts/rpm2cpio.sh;h=b03ee361f7f6948c979195eefc50295aa8fa0cf7;hb=HEAD So it affects RHEL6 as well as FC12 to FC15, which is why I put it there and not in RHN. So a fix should be pushed to FC14 & FC15 too Too late for 6.1, and in any case hardly critical as the "real" rpm2cpio can read packages with XZ payload just fine. Well I never said it was critical :-)
Still it's usefull when rpm is broken (shouldn't happen on RHEL but I've see usefull cases of rpm2cpio.{sh,pl} on desktop distros.
It's also usefull when trying to rebuild a newer SRPM on RHEL5.x
It can go as it into trunk and rpm-4.9.
It wouldn't hurt backporting it into the 4.6 branch, waiting for next security and/or fixes release.
I won't cry about it not being in RHEL just now (else I would have filled RHN instead :-))
Btw, I saw yesterday it's fixed in rpm-5.3 (not that I care about jbj stuff but it has slightly better logic that mine for handling xz/lzma). On the other hand, I did test my patch whereas I didn't test the "other" one.
See you

Created attachment 476415 [details] fix rpm2cpio.sh on RHEL6 Description of problem: /usr/lib/rpm/rpm2cpio.sh isn't able to extract files from rhel6 rpms due to the payload change (gzip compressed cpio archive -> xz compressed one) Attached patch fixes it Version-Release number of selected component (if applicable): rpm-4.8.0-12.el6.x86_64 How reproducible: Always Steps to Reproduce: 1. run that script on any package: 2. 3. Actual results: Error message: /usr/lib/rpm/rpm2cpio.sh libudev-147-2.29.el6.x86_64.rpm /usr/lib/rpm/rpm2cpio.sh: line 35: return: can only `return' from a function or Expected results: It should output a cpio archive like in the old days. Additional info: This is due to the payload format change between RHEL5 & RHEL6
