Bug 58364 – pppd or rp-pppoe fills system logs

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Cletus Lichte 2004-07-26 02:01:34 UTC]

I'm using rp-pppoe and whenever I reboot or shutdown, pppd fills my logs with thousands of the following line:

Jul 26 01:39:28 lichte pppd[7249]: Terminating on signal 15.

At one time I used sed to remove all these lines and my log went from 300 meg to 17 meg in size.  It sometimes also causes my system to overload during shutdown and makes it come to a crawl, outputting these lines, at least until syslog-ng stops, then shutdown resumes at normal speed.

I don't know if rp-pppoe or pppd is the cause of this problem.  Is there a way that I can get pppd to no longer send output to my system logs until this can get fixed???

Here are the versions of both those software packages:

net-dialup/rp-pppoe-3.5-r1 +X
net-dialup/ppp-2.4.2-r2 +activefilter -atm -ipv6 +pam

Ok, I rewrote the /usr/sbin/adsl-stop script and put the kill adsl-connect part before the kill pppd part.  It seems that rp-pppoe tries to restart the connection if it notices that pppd has stopped and this my be causing the problem.  I also changed all the kill lines to kill -9.  The offending lines in my /var/log/messages no longer show up.

Question, are the adsl scripts in the rp-pppoe package written by Gentoo devs, or by someone else?  I'd like to send the changes I made on to whomever can make use of them.  Thanks!

Well, I just took out the kill -9 to see if that was the fix, or if moving the one block of code was the fix.  With out the kill -9, I still get the problem with output lines in my messages file.  I also just noticed that in addition to filling my log file, pppd and pppoe don't ever stop running.  Oh well, with kill -9 the problem seems to be solved.

fixes endless loop when pppd is killed

[Comment 4 Michal Suchanek 2004-07-29 06:36:09 UTC]

There is a bug in pppd 2.4.2 which causes it to loop endlessly when it receives a signal.

The problem is described here: http://marc.theaimsgroup.com/?l=linux-ppp&m=107498594022952&w=2

attaching patch

[Comment 5 Cletus Lichte 2004-08-11 10:46:41 UTC]

Will this make it into portage soon?

[Comment 6 Michal Suchanek 2004-08-13 07:31:27 UTC]

perhaps if you put the Inclusion keyword to this bug you wold attract some more attention?
I cannot even do that.

[Comment 7 Heinrich Wendel (RETIRED) 2004-09-27 03:42:04 UTC]

added the patch.
