You can avoid rebuilding glibc by implementing the functions that you want to override in a shared object, and using system-wide preloading by specifying the library in /etc/ld.so.preload. See the man page ld.so(8) That won't catch statically-linked binaries, but neither will rebuilding glibc, unless you relink all of the static binaries. As for how to write an ELF interposer, see the following article. It's about Solaris, but applies equally to Linux -- just be aware that gcc requires different args that Sun CC for producing shared objects: http://developers.sun.com/solaris/articles/lib_interposers.html The Program-Library-HOWTO details how to create a shared library on Linux using gcc: http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-formats/html_single/Program-Library-HOWTO.html#AEN95 Regards, Bill Rugolsky _______________________________________________ Redhat-devel-list mailing list Redhat-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/redhat-devel-list
