This has now been verified (in a slightly modified revision, see below) on an
Athlon 64 system, running Fedora Core 5 with SELinux enabled (Sun internal:
of-1).
The initial change in /bridges/source/cpp_uno/shared/vtablefactory.cxx had to be
adapted again, similiar to what cmc proposed recently: an mmap (PROT_READ |
PROT_WRITE | PROT_EXEC) will fail with "allow_execmem = false". Anon memory
needs to be mmap()'d w/o PROT_EXEC, and lateron mprotected() to become
executable.
The apparently most clean solution (memory protection wise) is in cmc's 2nd
patch (of Mar 20): allocate writeable memory, assemble the code snippets, then
mprotect() to PROT_READ+PROT_EXEC.
But, even that may fail when "allow_execmod = false" which would let the
mprotect() call fail as well (though I haven't tested this myself).
Anyway, the fix is verified to work under "allow_execmem = false" => verified.
