Description

This is basically an import from the original code in purple2 with some clean
ups.

Testing Done

ran traversity-test on Debian Bookworm AMD64, OpenBSD 7.1 64bit, Freebsd 13.1 32bit, macOS Monterey 64bit, and Haiku OS (not sure version/arch).

I also force the ioctl path on all of them, Haiku only uses the ioctl path, but OpenBSD does not support the ioctl path.

Should we add some error information to error here in case of tmp being NULL? inet_ntop sets errno.	ivanhoe	Nov. 2, 2022, 7:55 p.m.
freeifaddrs is not called in case if this early return.	ivanhoe	Nov. 7, 2022, 4:55 p.m.
Should we use error to collect possible errors from socket, ioctl, and inet_ntop?	ivanhoe	Nov. 2, 2022, 7:55 p.m.
Is this a typo or some special version of ioctl that returns the error code? Judging from the Linux man …	ivanhoe	Nov. 7, 2022, 4:56 p.m.

traversity/traversitycoreunix.c (Diff revision 1)

The man page of netdevice suggests the following regarding the size of buffer:
If  the  size  specified by ifc_len is insufficient to store all the addresses, the kernel will skip the exceeding ones and return success.  There is no reliable way of detecting this condition once it has occurred.  It is therefore recommended to either determine the necessary buffer size beforehand by calling SIOCGIFCONF with ifc_req set to NULL, or to retry the call with a bigger buffer whenever ifc_len upon return differs by less than sizeof(struct ifreq) from its original value.

special case haiku as it doesn't support calling SIOCGIFCONF with a NULL parameter to get the buffer size.

Is this a typo or some special version of ioctl that returns the error code? Judging from the Linux man page of ioctl this should be g_strerror(errno). Same issue on line 161.
