[DRE-maint] Bug#788939: ruby-sigar: Function sigar_proc_port_get sometimes does not find valid PID

[Piotr Panczyk]

Package: ruby-sigar
Version: 0.7.2-1
Severity: important
Tags: upstream patch

Dear Maintainer,
There is a problem with sigar_proc_port_get function. While looking for
the process that owns a socket, it assumes that the UID of the process
is the same as the UID of the port, which is not always true. I use Chef
to configure some servers, Chef calls Ohai, which uses the function to
generate the port-process map. When a process was started as root,
opened a socket and then dropped priviliges, the function returns 0,
which causes some problems with Ohai and Chef. I tried deleting the
lines related to skipping processes with different UID - after
installing the rebuilt package everything is working fine. I attach
the patch.

Best regards,
Piotr Panczyk
