Description Ivana Varekova 2005-08-03 14:48:25 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323 Firefox/1.0.2 Fedora/1.0.2-1.3.1

Description of problem:
acct() does not have Large File support. If acct() input file is larger than 2GBs,  acct() does not start process accounting. 

Version-Release number of selected component (if applicable):
kernel-2.4.21-32.EL.ppc64pseries

How reproducible:
Always

Steps to Reproduce:
1. use acct() system call with >2GBs input file. 
2.
3.
  

Actual Results:  accton: File too large

process accounting does not start

Expected Results:  process accounting starts

Additional info:

Ernie Petrides's comment:
I believe the handling for the acct() system call within the kernel needs
to add the O_LARGEFILE flag into the 2nd argument in the call to the
filp_open() function from the sys_acct() function (in kernel/acct.c) to
avoid SIGXFSZ signals being sent to commands while accounting is enabled
and the accounting file has exceeded 2 GBs in size.
Comment 1 Peter Staubach 2005-08-08 19:40:55 UTC 
The kernel changes to handle a large accounting file seem fairly obvious.
The change is as Ernie suggests.  The rest of the accounting support in
the kernel looks large file safe.

However, are the user level programs to deal with the accounting file
at least largefile aware or perhaps largefile safe?
Comment 2 Peter Staubach 2005-08-08 19:45:09 UTC 
Just dug up the user level code and it does apper to be largefile safe.

A fix for this problem has just been committed to the RHEL3 U7
