Bug 74924 – ulogd cant handle logfiles larger than 2 GB, suggestion for correction attached

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Lasse B. Jensen 2004-12-19 03:54:59 UTC]

ulogd cant handle logfiles larger than 2 GB, when filesize of the logfile reaches 2GB the daemon stop logging with no warning.

A fix to the problem is to apply the -D_FILE_OFFSET_BITS=64 gcc flag when compiling. I works on my platform and should work on others.





Reproducible: Always
Steps to Reproduce:
1. Start ulogd using ulogd_LOGEMU plugin log to a file
2. log things via ulog to ulogd in iptables
3. when filesize reaches 2 GB ulogd closes with no warning just stops

Actual Results:  
Logfile isnt complete several hours of log is missing. 

Expected Results:  
Logged everything

Offcourse this is with ebuild app-admin/ulogd/ulogd-1.02.ebuild i have problems ;)

[Comment 2 Daniel Ahlberg (RETIRED) 2005-01-01 11:09:24 UTC]

Added to CVS, thanks!

[Comment 3 Lasse B. Jensen 2005-01-07 12:43:59 UTC]

The new 1.02-r1 doesnt work yet.

The compile flags has to be added in both extensions/Makefile and Makefile

its missing i extension/Makefile i think

[Comment 4 Lasse B. Jensen 2005-01-07 12:52:24 UTC]

It has to be done such that the changes will be in Rules.make after configure script has been running.
 
emerge 
CFLAGS=-O2 -march=pentium4 -fomit-frame-pointer -pipe
CFLAGS+=-DULOGD_CONFIGFILE=\"$(ULOGD_CONFIGFILE)\"

compiling myself with manual addition of 
CFLAGS=-O2 
CFLAGS+=-DULOGD_CONFIGFILE=\"$(ULOGD_CONFIGFILE)\"

adding -D_FILE_OFFSET_BITS=64

CFLAGS=-O2 -D_FILE_OFFSET_BITS=64
CFLAGS+=-DULOGD_CONFIGFILE=\"$(ULOGD_CONFIGFILE)\"

then ulogd works because Rules.make is included in extensions/Makefile

doh, I forgot to inherit flag-o-matic that makes append-flags work.

[Comment 6 Lasse B. Jensen 2005-01-07 13:28:48 UTC]

I test it as soon its in portage will it be 1.02-r2?
