How do I report a bug (or at least ask for help) in a newer kernel?
(The gory details are below, if you are interested.) I sent some
email to a developer whose name I found in the suspect source, but I
did not get any response. Any suggestions?
TIA,
Bill

Subject: nfs readdir bug?
Claus,
I am reporting a bug that I suspect is in nfs readdir. I am reporting
it to you, because I found your email address in the source. If this
is wrong, please tell me.
Symptom: Several programs (details below) do not read the contents of
an nfs-mounted directory. There is no indicated failure -- there just
is no data. The nfs server is DG/UX. The nfs client is linux, kernel
version 2.4.16. The problem does not show up with the 2.4.2 kernel
(RedHat 7.1 dist.) or on nfs systems from a SUN server.
Note: We are using reiserfs on an array which is locally mounted to
the linux host. The hardware is: DG (Data General) Aviion 8900 4
cpu, 500 MHz.
strace note: I ran strace on my program. It reported that getdents64
function was finding the right number of directory entries.
****************
These operations/programs fail to read a directory. In all cases, the
OS is linux 2.4.16 and the filesystem is served by DG/UX. All
directories (that I tested) on the filesystem have the problem.
tcsh file completion (using the tab key)
readdir in Perl
readdir in my own test program (included below)
****************
These operations work with the 2.4.16 kernel.
All operations on other filesystems, nfs (SUN server) and local
The "ls" command works everywhere
Thanks for your time.

Here's the source for my test program:
#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>
int main(int argc, char *argv[]) {
DIR *dir;
struct dirent *dirent;
printf("Reading %s\n", argv[1]);
dir = opendir(argv[1]);
while((dirent = readdir(dir))) {
printf("%s\n", dirent->d_name);
}
return (0);
}
