State-Changed-Why:
This PR was solved in a rather unusual way. Maxim Sobolev came up with a
workaround for the problem. That workaround is detailed below.
-- From Maxim Sobolev <sobomax@FreeBSD.org>
Aha, I suspected something like that. Try attached program instead.
Use it as follows:
1. Compile with:
$ cc -shared getresuid.c -o /some/path/getresuid.so
2. Set LD_PRELOAD variable to contain path to getresuid.so and invoke
applix:
$ export LD_PRELOAD=/some/path/getresuid.so
$ [run applix]
-- getresuid.c
#include <sys/types.h>
#include <dlfcn.h>
#include <unistd.h>
static int (*getresuid_p)(uid_t *, uid_t *, uid_t *) = NULL;
int
getresuid(uid_t *ruid, uid_t *euid, uid_t *suid)
{
void *tmp;
if (getresuid_p == NULL) {
tmp = dlopen("/usr/lib/libc.so", RTLD_LAZY);
getresuid_p = dlsym(tmp, "getresuid");
}
return getresuid_p(ruid, euid, suid);
}
-- End workaround
