Description malte.sackmann 2001-01-18 10:00:01 UTC

Its not possible to lookup all files in an directory if using
a linux binary under xwindows.

How-To-Repeat: Install a linux binary and open for example "/etc/*". 
You will not see all existent files in that directory.
You will see always the same randomly chosen 8 files.
Try it with acroread or scilab.

You are probably seeing the contents of /compat/linux/etc because
programs run under Linux compatability look for a version of the
file/directory under /compat/linux before they look starting at /.

We have shortly  discovered that the content from the /etc diretory
comes of course from /compat/linux/etc. No question.
But the problem with other directory contents is still the same!!!!

For example a mounted cdrom /cdrom with strongly missing directories
(some appeared, most disappeared) and files or various user/system
directories. Tested for example with linux netscape (from FreeBSD-4.1.1
packages), acrobat4 . All programs show the same files/dirs or not.
We have done some debugging in the kernel source code (mainly
sys/i386/linux/linux_file.c) and have seen, that indeed the
getdents function only returns some of the entries of the specific
directory. But, from this already shrinked converted dir list (with
missing entries), additionaly some files/dirs lost "on the way" to the
user program and were never shown by the user program. 
Very strange and serious problem.

Bye,

Malte & Stefan

I'm pretty sure this is the same problem reported in PR kern/19407.
There was a bug in the Linuxulator that caused the linux readdir(3)
to prematurely return NULL on non-UFS partitions.  Your Linux
programs can correctly read Freebsd partitions, right?

Marcel Moolenaar fixed the problem shortly before 4.2-Release.
So, upgrade to 4.2 or later and see if that fixes the problem.

ISTR this problem being fixed recently in -stable - can you confirm?
