Hi all, In Gentoo, we notice some unexpected behavior with the compiled file_contexts files after upgrading (lib)pcre: https://bugs.gentoo.org/show_bug.cgi?id=516608 I think what is happening is that the pcre data, which is built with one pcre version, is not (fully) compatible with a more recent pcre version. In the changelog of pcre I find type changes of (internal or not) variables by pcre. If this assumption is correct, perhaps we should store the pcre version used to build the *.bin files in the file itself. Right now we store a magic (to make sure it is a compiled file_contexts file) and a version specific for libselinux, but not a version specific for PCRE. The pcre header defines PCRE_MAJOR and PCRE_MINOR which we can use. Do you think the above analysis makes sense? The bug linked earlier on has a gdb backtrace for those interested. Any other pointers that might help us troubleshoot this would be appreciated.
