The config file can specify a dhclient script, which gets used instead
of what NM passes on the command-line. Make sure that script gets
ignored in the final dhclient config, because the script NM passes
is the script that needs to be used to pass data back to NM. People
may have old dhclient.conf files lying around that get picked up and
we don't want any script specified there to interfere.
The DUID is supposed to be machine-wide, so if we're writing a new
leasefile, save the default DUID to it. If we haven't saved a
persistent DUID yet, do that to.
Add infrastructure for generating DUID-LLT from a given device MAC and
passing it around to the DHCP client implementations.
Thanks to Mathieu Trudel-Lapierre for bug fixes in the
unescaping code, which were merged into this commit.
This patch makes DHCPv6 support more or less equivalent to that
one of IPv4 DHCP.
(dcbw: fix some formatting, rearrange code so it's less convoluted,
fix up writing hostname to ifcfg files)
The ctype macros (eg, isalnum(), tolower()) are locale-dependent. Use
glib's ASCII-only versions instead.
Also, replace isascii() with g_ascii_isprint(), since isascii()
accepts control characters, which isn't what the code wanted in any of
the places where it was using it.
