This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. Working on a fix for this. Still working on this. I've been informed that this should be checked in ASAP e.g. tonight or tomorrow. I can't get it all done tonight, I still need some more testing. Likely tomorrow morning, and post upstream, and get it into rawhide. Any other branches that this needs checking into? Please check in to both f18 updates and rawhide. Retesting patch. Patch sent upstream: http://sourceware.org/ml/libc-alpha/2013-02/msg00120.html We want to reserve the ld.so.cache value with upstream before we use it. Upstream accepted the patch. I'll commit upstream tomorrow. I'm almost done the rawhide commit, but I've run out of time tonight. I'll commit rawhide tomorrow morning. Following the rawhide committ I'll do a larger backport to F18. The F18 backport requires more additional changes and more testing. The fix for this is in rawhide and thus F19. Still working on the F18 fix. Committed upstream: commit b39949d21179bd0b08a083e4f7e35d0c98e11294 Author: Carlos O'Donell <carlos> Date: Fri Feb 8 12:26:12 2013 -0500 ARM: Support loading unmarked objects from cache. ARM now supports loading unmarked objects from the dynamic loader cache. Unmarked objects can be used with the hard-float or soft-float ABI. We must support loading unmarked objects during the transition period from a binutils that does not mark objects to one that does mark them with the correct ELF flags. Signed-off-by: Carlos O'Donell <carlos> Brendan, Can you confirm that you actually see this issue in F18? The F18 glibc is based on 2.16 which doesn't have any of the code to safely support mixed ABI environments. The 2.16 loader will load any of the objects from any of the ABIs. Therefore there can be no bug in F18. At best it would be a new feature request for F18. Can you confirm please? Have not observed on F18. As long as an F18 doesn't contain the mixed ABI recognition code we no need to do anything there. Fixed in F-19+ |
