[Touch-packages] [Bug 1627769] Re: limits.conf not applied

2017-06-06 Thread Christopher Warner
So i'm just going to add on here instead of opening a new bug report.
The problem is that in most cases when you're setting the limits, you're
doing so for a process/user that isn't going to login. So the default is
to set it in login, cron, sshd, su etc. Unfortunately, for a process
that isn't going to login via normal methods. Such as a server process
or the like this will be ignored because pam_limits.so will never be
activated.

We need to put pam_limits.so in /etc/pam.d/common-session and /etc/pam.d
/common-session-noninteractive as required by default, or, update the
documentation somewhere that notes that limits.conf will not be
activated by pam_limits.so otherwise. Since everything is already
commented out by limits.conf per default it should be a straight-forward
change.

Bug description:
  Since upgraded to 16.10 Yakkety, modifications in
  /etc/security/limits.conf are not taken into consideration when
  logging in the graphical interface.

  
  /etc/security/limits.conf:
  @audio   -  rtprio 99
  @audio   -  memlockunlimited

  I tried the same settings in /etc/security/limits.d/audio.conf, to the
  same results.

  
  After logging in Unity, opening a console, the limits are not set:
  blablack@ideaon:~$ ulimit -l -r
  max locked memory   (kbytes, -l) 64
  real-time priority  (-r) 0

  
  Reloging to my user via bash DOES apply the limits:
  blablack@ideaon:~$ ulimit -l -r
  max locked memory   (kbytes, -l) 64
  real-time priority  (-r) 0
  blablack@ideaon:~$ su blablack
  Password: 
  blablack@ideaon:~$ ulimit -l -r
  max locked memory   (kbytes, -l) unlimited
  real-time priority  (-r) 95

  
  Switching to a console (ctrl+alt+f1) and logging in would apply the limits as 
well.



  The exact same setup used to work fine on Xenial 16.04 before upgrade.

  
  If you need any more information, please let me know.

[Touch-packages] [Bug 1816811] [NEW] iptables package doesn't flush table on removal of package

2019-02-20 Thread Christopher Warner
Public bug reported:

The iptables package isn't flushing all tables on removal of the package
and the tables still exist until reboot. Intended behavior should be to
flush all tables via a dpkg pre-removal script. I'm not sure of any use
case where the intended behavior would be to keep the current rules in
place but not have iptables available.
