Re: [systemd-devel] Port 231 security patch to 213

2016-10-24 Thread Jay Burger

Christian,

Found the fix here:

https://github.com/systemd/systemd/pull/4240

This seems to work, I no longer have an issue even with the
endless loop option used to create the problem.

Hi,

I need some help porting the security patch released in version 231 back
to version 213. If this is not the correct place for this question can
someone point me to the proper forum?

Updating my system from 213 to 231 is not an option for me at this time.
If anyone knows if this has been done can you point me to the patch?

What exactly are you referring to?

Does this help? (There is no v213 tree, but v214 is next.)

Hi Andrei,

Thanks for the quick reply. *"Most simple answer - it tries to find C in
PATH and PATH in*
*your login session is different from PATH systemd uses.*
*​"*​

​I have all the binaries placed in a single environment file and my unit
file includes that environment file. So ideally it should take all the
binaries from PATH environment variable right.

This is outside of scope of systemd. You need to debug B why it fails to
start C. Most simple answer - it tries to find C in PATH and PATH in
your login session is different from PATH systemd uses.

[systemd-devel] Applications using mulitple fork() in SystemD

2016-10-24 Thread Raghavendra. H. R
Hi All,

I'm a newbie and exploring Systemd init system and I have a doubt regarding
how multiple fork() from an application is handled in SystemD environment.

I have application of process A, which forks process B and B in turn forks
another process C like A -> B -> C.

*My systemd service file will spawn the application and starts process A
and I can see that only process B is forked but not process C.*

Below given is my unit file.

*[Unit]*
*Description=Multiple fork*

*[Service]*
*ExecStart=/etc/A*

*[Install]*
*WantedBy=multi-user.target*


Instead of running in a unit file, if I run my application manually all the
processes will spawned.
For Eg :
==
cd /etc
./A & ---> this will cause all the 3 process to be spawned

Can anyone let me know how to resolve this issue in SystemD ?
Like *"Type=forking", *do we have any other option which helps in achieving
this problem statement.

Re: [systemd-devel] Port 231 security patch to 213

2016-10-24 Thread Jay Burger

Christian,

I am using a Yocto distribution "daisy" which is on version 211, they have
provided recipe updates to what they call systemd 213.

I am referring to the patch as discussed on the following site:

https://threatpost.com/hack-crashes-linux-distros-with-48-characters-of-code/121052/

This claims the problem began is version 209.

I found the systemd-231-security_fix-1.patch on this page but am not sure if it 
applies.


http://www.linuxfromscratch.org/patches/downloads/systemd/

Thanks for your help.

-Jay
