Anindya Sinha commented on MESOS-1835:
--------------------------------------
inet_pton returns network order which is big endian. So, 127.0.0.1 is stored as
0x100007f (16777343) when stored in __ip__ on little endian machines. However,
check for __ip__ is being done for 2130706433. So that check fails.
On big endian machines, __ip__ should be stored as 0x7f000001 (2130706433)
although I do not have means to verify this, and hence the check for __ip__ ==
2130706433 would succeed.
> Check for IP address being localhost not platform independent

> URL: https://issues.apache.org/jira/browse/MESOS-1835
> Project: Mesos
> Issue Type: Bug
> Components: libprocess
> Affects Versions: 0.20.1
> Reporter: Anindya Sinha
> Assignee: Evelina Dumitrescu
>
> In process::initialize() [3rdparty/src/libprocess/process.cpp], check for
> __ip__ for localhost (127.0.0.1) is done by checking if __ip__ == 2130706433.
> However, it could be either 2130706433 or 16777343 depending on endianness.
> This check should succeed independent of the endianness, so would be good to
> do a 'inet_ntop' and then compare against the string for 127.0.0.1.
