dhcp-client: Ignore partial checksums

2015-02-14T08:33:41+00:00

dhclient will fail to get an IP address if run inside a guest when traffic is
flowing over a virtual network interface.  The user will see the error
message:

  5 bad udp checksums in 5 packets
  No DHCPOFFERS received.
  Unable to obtain a lease on first try.  Exiting.
  Failed to bring up eth0.

This is because Linux only uses partial checksums for packets that go over
virtual network interfaces and dhclient does not like this.

  See linux kernel commit 78ea85f17b15390e30d8b47488ec7b6cf0790663
  ("net: skbuff: improve comment on checksumming")

An application can detect this behaviour by checking for the
TP_STATUS_CSUMNOTREADY flag in the tp_status field.

  See linux kernel commit 8dc4194474159660d7f37c495e3fc3f10d0db8cc
  ("Add optional checksum computation for recvmsg")

An extra parameter is added to decode_udp_ip_header() in dhclient to indicate
whether or not dhclient should ignore partial checksums.  This is used
when the TP_STATUS_CSUMNOTREADY bit is set by the guest kernel.

This fix has been included in Fedora and Ubuntu, however it has not yet been
accepted by ISC upstream.  Likely because it is specific to behaviour in Linux
and other UNIX variants do not seem to be affected.

The patch was imported from the dhcp source RPM in Fedora 21
  (http://pkgs.fedoraproject.org/cgit/dhcp.git/tree/dhcp-xen-checksum.patch?h=f21)

dhcp: not override site.h

2015-01-23T11:35:28+00:00

Previously, site.h was overridden for setting _PATH_DHCPD_CONF
and _PATH_DHCLIENT_CONF, it caused other MACROs were missing,
so we use a patch to instead.

The macros NSUPDATE and COMPACT_LEASES existed in site.h

dhcp: use ${PN} for SYSTEMD_SERVICES

2014-09-29T11:11:49+00:00

We should use ${PN} instead of hardcoding 'dhcp' for SYSTEMD_SERVICES,
otherwise we would have 'installed-not-shipped' QA error if we are building
lib32-dhcp.

dhcp: do not use ifconfig/route in dhclient-script

2014-08-23T08:25:05+00:00

The original patch was submitted on ISC's mailing list but it didn't get merged
for some reason, it can be found here;

https://lists.isc.org/pipermail/dhcp-users/2011-January/012910.html

"The ISC DHCP's dhclient-script for Linux still uses the legacy commands
'ifconfig' & 'route' to manage IPv4 network addresses & routes,
while it uses iproute2's new "ip" command to manage IPv6 network data.

This requires users & distributions to have both types of commands installed

The attached patch tries to improve the situation by replacing the
old "ifconfig" resp. "route" commands with their "ip" counterparts.

It even improves the logic a bit by only flushing the IPv4 addresses
instead of taking down the whole interface, which may still have active IPv6
connections."

dhcp-client: fix invoke dhclient-script failed on Read-only file system

2014-03-07T14:57:39+00:00

In read-only file system, '/etc' is on the readonly partition,
and '/etc/resolv.conf' is symlinked to a separate writable
partition.

In this situation, we should use shell variable to instead of
the temp file '/etc/resolv.conf.dhclient'.
