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 **************************************************************** Date: Fri, 25 Jan 2002 14:40:01 -0500 (EST) From: Bill Mills-Curran <Mills-Curran_Bill@emc.com> To: claus@momo.math.rwth-aachen.de 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.
