Re: [systemd-devel] Port 231 security patch to 213
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. -Jay On 10/24/16 11:11, Christian Hesse wrote: Jay Burger on Mon, 2016/10/24 10:54: Hi, I need some help porting the security patch released in version 231 back to version 213.

Re: [systemd-devel] Applications using mulitple fork() in SystemD
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. -- Regards, Raghavendra. H.

This is outside of scope of systemd. You need to debug B why it fails to start C.

[systemd-devel] Applications using mulitple fork() in SystemD
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. -- Regards, Raghavendra. H.

Re: [systemd-devel] Port 231 security patch to 213
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 On 10/24/16 11:11, Christian Hesse wrote: Jay Burger on Mon, 2016/10/24 10:54: Hi, I need some help porting the security patch released in version 231 back to version 213.
