Description Steve Bonds 2005-04-19 17:38:28 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041003 Firefox/0.10

Description of problem:
When I redirect output to a location where I would expect to get "permission denied", I instead get "No such file or directory".

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. log in as a user that can't write to /
2. run the command ">/tempfile"


Actual Results:  The shell returns the error "-bash: /tempfile: No such file or directory"

Expected Results:  The shell should have returned the error "bash: /tempfile: Permission denied"  (This is the Red Hat Enterprise 3 behavior.)

Additional info:

An "strace" of the improper behavior (strace sh -c ">/tempfile") shows:

open("/tempfile", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = -1 EACCES (Permission denied)
open("/tempfile", O_WRONLY|O_TRUNC|O_LARGEFILE) = -1 ENOENT (No such file or directory)

It seems that the failure of the first open() is not being detected and the errno from the second open() without O_CREAT is the one getting passed back to the error handler.  In Red Hat Enterprise 3, there is only one open():

open("/tempfile", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = -1 EACCES (Permission denied)

This was caused by AFS support.  A fix has been committed to CVS for Fedora
development.  Thanks for the report.
