Control: severity -1 wishlist Control: reassign -1 libc6 Control: retitle -1 ld-linux.so loads libraries from . when /proc is not mounted Control: affects -1 + ghc Control: summary -1 0
When /proc is not mounted, a relative RPATH causes ld-linux.so to fall back to using the working directory as the base directory for RPATH resolution instead of using the (unknown) location of the executed binary. This issue is hard to diagnose, because the error message does not make it clear that fallback code is in use due to readlink /proc/self/exe failing. Furthermore, it may pose a security risk by loading libraries from unintended locations.

Steps to reproduce (for glibc maintainers): Create an unstable chroot. Install ghc. Do not mount /proc in that chroot. Execute /usr/bin/ghc. You shall see that it fails loading libraries. I assume that any binary with a relative RPATH is affected. Helmut -- To UNSUBSCRIBE, email to debian-glibc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
