[Touch-packages] [Bug 1190344] Re: lightdm is leaking FDs -fix
** Description changed:
[Impact]
- LightDM doesn't close the server side end of the pipes used to communicate
with session processes. This means each session that is created leaks two file
descriptors eventually leading to the system stopping it from creating new
pipes.
+ LightDM doesn't close the server side end of the pipes used to communicate
with session processes and greeters. This means each session/greeter that is
created leaks two file descriptors eventually leading to the system stopping it
from creating new pipes.
[Test Case]
1. Start LightDM
2. Check how many pipes are open
# lsof -p {lightdm_pid} | grep FIFO | wc -l
3. Create sessions by either cycling between users in Unity Greeter or
logging in and out
4. Check how many pipes exist using step 2.
Expected result:
No more pipes should be open
Observed result:
Many pipes remain open
[Regression Potential]
Low. Fix is to close pipes when finished with them. Tested with regression
tests.
** Summary changed:
- lightdm is leaking FDs -fix
+ Daemon end of session/greeter pipes not closed

Hmm, turns out I only committed the session leak from the attached patch
and not the greeter leak. I've committed that fix now.

Even thought this does not address the bug completely, can the lightdm
update be released none-the-less? as it does not degrade beyond what's
in current release/updates pockets?

3. Create sessions by either cycling between users in Unity Greeter or
logging in and out

Expected result:
No more pipes should be open
Observed result:
Many pipes remain open
[Regression Potential]
Low. Fix is to close pipes when finished with them. Tested with regression
tests.

[Touch-packages] [Bug 1190344] Re: lightdm is leaking FDs -fix
Hello rumen, or anyone else affected,
Accepted lightdm into trusty-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/lightdm/1.10.4-0ubuntu2 in a few
hours, and then in the -proposed repository.
Please help us by testing this new package. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed. Your feedback will aid us getting this update
out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed. In either case, details of your testing will help
us make a better decision.
Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance!

LightDM doesn't close the server side end of the pipes used to communicate
with session processes. This means each session that is created leaks two file
descriptors eventually leading to the system stopping it from creating new
pipes.

Description of problem:
Each time the greeter starts the number of open FDs increase. After each
login and logout cycle the number of open FDs is increased. Which over time
leads to impossible logins and the message in /var/log/messages is:
Jun 12 02:44:24 node3 lightdm[17471]: ** (lightdm:17471): WARNING **: Failed
to create pipe to communicate with session process: To...en files
Jun 12 02:45:29 node3 lightdm[17471]: ** (lightdm:17471): WARNING **: Failed
to create pipes: Too many open files
Jun 12 02:47:47 node3 lightdm[17471]: ** (lightdm:17471): WARNING **: Failed
to create pipes: Too many open files
Tested on:
Fedora 19 and Ubuntu 13.04 - lightdm 1.6.0
Steps to Reproduce:
1. login on a console and find the pid of main lightdm process then:
# lsof -p {lightdm_pid} |grep FIFO |wc -l
26
2. switch to X console and login through lightdm and then logout
3. go back on comsole
# lsof -p {lightdm_pid} |grep FIFO |wc -l
32
Here is a patch that fixes the issue. It may have several lines offset
because we use modified lightdm but it is good for the original
version too.

Rumen

Bug description:
Description of problem:
Each time the greeter starts the number of open FDs increase. After each
login and logout cycle the number of open FDs is increased. Which over time
leads to impossible logins and the message in /var/log/messages is:
Jun 12 02:44:24 node3 lightdm[17471]: ** (lightdm:17471): WARNING **: Failed
to create pipe to communicate with session process: To...en files
Jun 12 02:45:29 node3 lightdm[17471]: ** (lightdm:17471): WARNING **: Failed
to create pipes: Too many open files
Jun 12 02:47:47 node3 lightdm[17471]: ** (lightdm:17471): WARNING **: Failed
to create pipes: Too many open files
Tested on:
Fedora 19 and Ubuntu 13.04 - lightdm 1.6.0
Steps to Reproduce:
1. login on a console and find the pid of main lightdm process then:
# lsof -p {lightdm_pid} |grep FIFO |wc -l
26
2. switch to X console and login through lightdm and then logout
3. go back on comsole
# lsof -p {lightdm_pid} |grep FIFO |wc -l
32
Here is a patch that fixes the issue. It may have several lines offset
because we use modified lightdm but it is good for the original
version too.
regards,
Rumen
