Hi,
Sorry, I do not have a freebsd machine, so I can not use the send-pr
program to send this.
dlfunc is implememted in libc/gen and simply calls dlsym, this works
fine when doing normal lookups, but is broken for RTLD_{NEXT,SELF}.
http://www.pogma.com/fink/dltest.tar should demonstrate the problem ( I
am not sure that this list takes attachments).
One solution would be to move dlfunc to libexec/rtld-elf (or whatever
that is called), rename dlsym to something else (e.g. dlsym_real) make
it static,change the __builtin_return(0) to __builtin_return(1), make a
new dlsym function which calls dlsym_real (that way dlsym_real is
always called with one level of indirection from both dlsym and dlfunc
).
But, you guys can fix it however you please :)
I was just peeking at your source code looking for idea's for
opendarwin.org's dlcompat project, Shantonu Sen - ssen at opendarwin
dot org - kindly ran the test code for me on his freebsd 5.0 machine.
Thanks,
Peter
