|
||||
o Major refactoring:
|
||||
- Refactor the get_interface_addresses_raw() Doom-function into
|
||||
multiple smaller and easier to understand subfunctions. Cover the
|
||||
resulting subfunctions with unit-tests. Fixes a significant portion
|
||||
of issue 12376.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Fix the ioctl()-based network interface lookup code so that it will
|
||||
work on systems that have variable-length struct ifreq, for example
|
||||
Mac OS X.
