Package: sudo
Version: 1.6.9p6-1
On a setup where the limit for open files is set to 1048576, sudo takes half
a second to do the simplest task. The reason behind this is that at startup
it closes all fds after the one associated with stderr, which makes 1048573
system calls.
There is code in sudo which looks for open fds in /dev/fd/, but the
configure fails to detect that the libc has dirfd, and so sudo uses the dumb
algorithm.
Configure tries to compile this code,
#include <sys/types.h>
#include <dirent.h>
int
main ()
{
DIR d; (void)dirfd(&d);
;
return 0;
}
which fails because the glibc (at least in 2.6.1-1+b1) includes do not
expose the structure of a DIR * (and there seems no reason to do so)
I suggest the following patch be applied. (autoconf has to be rerun after
this)
