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):
Steps to Reproduce:
1. use acct() system call with >2GBs input file.
Actual Results: accton: File too large
process accounting does not start
Expected Results: process accounting starts
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.
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?
Just dug up the user level code and it does apper to be largefile safe.
