A test for this bug is:
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <pwd.h>
int main()
{
setpassent(1);
getpwent();
chroot("/usr");
chdir("/");
if(!getpwuid(0)) {
printf("setpassent doesn't appear to work\n");
} else {
if(!getpwuid(0))
printf("second getpwuid(0) didn't work\n");
else
printf("setpassent works\n");
}
return 0;
}
Right now, the second getpwuid(0) call fails. Adding the if (!_pw_stayopen)
before the endpwent() in both getpwnam() and getpwuid() lets this test pass,
but is it a sufficient fix?
Is a closing call to endpwent() necessary for a program to correctly close
the database?
