isc-dhcp (4.3.5-3ubuntu1.1) zesty; urgency=medium

  * debian/initramfs-tools/lib/etc/dhcp/dhclient-enter-hooks.d/config: fix the
logic for handling search domains to also write it to the output file when
only the domain name is provided by the DHCP server. Copied code from
debian/dhclient-script.linux. (LP: #1713747)

  [Impact]
  Systems booted off the network where the DHCP server provides a domain name 
but no search domains may wish to rely on the domain name as a search value (as 
is done in isc-dhcp in userland, outside the initramfs), to be able to use 
short names for resolving hosts.

  [Test cases]
  1) Boot a system with a remote root over the network
   - Typically this requires adding ip=(some IP settings) or ip=dhcp on the 
kernel command-line, and is better done automatically.
  One good setup for this is to use MaaS to configure the system; where it will 
require a remote root over iSCSI.
  2) Break boot in the initramfs (adding 'break=bottom' or 'break=premount' to 
stop in the initramfs at its end, or just before it mounts filesystems)
  3) Validate the contents of /etc/resolv.conf and /run/net-*.conf.

  [Regression potential]
  Potential regressions would include incorrectly resolving names, bad 
configuration of /etc/resolv.conf (invalid values for the fields, or missing 
fields), or even failure to mount the remote root in the cases where name 
resolution is required to find the remote server.

  --

  For networked systems, for instance booting with an iSCSI root,
  dhclient writes an output file in the form of /run/net-.conf
  that contains data for other programs to consume. This allows, for
  instance, open-iscsi to get the right information and properly connect
  to the server to mount the root filesystem.

  It is common for DHCP servers to only provide a domain name value, and
  no search domains. In this case, isc-dhcp doesn't currently write
  DOMAINSEARCH, but people may wish to use short names to resolve things
  (such as in iSCSI server).

  In the not-initramfs dhclient-script, when domain_search isn't
  provided but domain_name is, domain_name is written to the search
  string. If both are provided, domain_search is written. The initramfs
  enter hook should do the same.

[Touch-packages] [Bug 1713747] Re: missing DOMAINSEARCH in initramfs output files if the DHCP server doesn't provide one

[Mathieu Trudel-Lapierre]

Verification done for isc-dhcp 4.3.5-3ubuntu1.1 as well:

If you manually enable using dhclient for ipv4 networking in the
initramfs, the system behaves as expected and correctly writes
DOMAINSEARCH in the /run/net-*.conf files. Ipv4 is not handled by
dhclient by default (but uses klibc instead) hence the need to modify
scripts.

[Touch-packages] [Bug 1713747] Re: missing DOMAINSEARCH in initramfs output files if the DHCP server doesn't provide one

[Mathieu Trudel-Lapierre]

Verification-done for xenial with klibc 2.0.4-8ubuntu1.16.04.4:

I verified that updating klibc-utils to the new version yields a /run
/net-ens3.conf file that contains the proper value at DOMAINSEARCH=.

As for the above test on zesty, this involved modifying
scripts/functions to allow breaking the boot at initramfs after
networking to validate the file contents early.

[Touch-packages] [Bug 1713747] Re: missing DOMAINSEARCH in initramfs output files if the DHCP server doesn't provide one

[Mathieu Trudel-Lapierre]

Verification-done for zesty, with klibc-utils 2.0.4-8ubuntu4.1:

I updated klibc-utils and libklic; then modified the initramfs
scripts/functions to add "maybe-break networking" to the end of
configure_networking(); and rebooted with 'ip=dhcp break=networking'. I
could then verify the contents of /run/net-ens3.conf from the initramfs
environment; which checks out: DOMAINSEARCH shows the right value for
this network: "nat", same as DNSDOMAIN.

[Łukasz Zemczak]

I accepted the packages as is. Was worried a bit as the patch is not
handling the case of dev->dnsdomainname being NULL when being passed to
write_option() (causing a SEGFAULT), but as per discussion with Matt -
since upstream doesn't do a check for it != NULL it might mean such a
case is not really a possible edge case.

to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at

  [Impact]
  Systems booted off the network where the DHCP server provides a domain name 
but no search domains may wish to rely on the domain name as a search value (as 
is done in isc-dhcp in userland, outside the initramfs), to be able to use 
short names for resolving hosts.

  [Test cases]
  1) Boot a system with a remote root over the network
   - Typically this requires adding ip=(some IP settings) or ip=dhcp on the 
kernel command-line, and is better done automatically.
  One good setup for this is to use MaaS to configure the system; where it will 
require a remote root over iSCSI.
  2) Break boot in the initramfs (adding 'break=bottom' or 'break=premount' to 
stop in the initramfs at its end, or just before it mounts filesystems)
  3) Validate the contents of /etc/resolv.conf and /run/net-*.conf.

  [Regression potential]
  Potential regressions would include incorrectly resolving names, bad 
configuration of /etc/resolv.conf (invalid values for the fields, or missing 
fields), or even failure to mount the remote root in the cases where name 
resolution is required to find the remote server.

  --

  For networked systems, for instance booting with an iSCSI root,
  dhclient writes an output file in the form of /run/net-.conf

[Touch-packages] [Bug 1713747] Re: missing DOMAINSEARCH in initramfs output files if the DHCP server doesn't provide one

[Mathieu Trudel-Lapierre]

Turns out this is something directly in klibc in the case of xenial:
since xenial is not yet using isc-dhcp for IPv4 DHCP, since that was
deemed too intrusive a change for xenial.

In other words, while DHCPv6 is done via isc-dhcp, DHCPv4 is done via
ipconfig (klibc); which will need to be fixed to follow the same logic
as isc-dhcp w.r.t DOMAINSEARCH handling.

In general, I think having DOMAINSEARCH contain the existing DNS domain
if it's not otherwise set by the DHCP server is sensible.

I set the xenial task to High since it might actually impact a lot of
people, but it's not as high for artful/zesty given that isc-dhcp is
used instead (still ought to land there since people might want to use
ipconfig on their own, etc.).

Title:
  missing DOMAINSEARCH in initramfs output files if the DHCP server
  doesn't provide one

Status in isc-dhcp package in Ubuntu:
  Fix Released
Status in isc-dhcp source package in Xenial:
  In Progress
Status in isc-dhcp source package in Zesty:
  Triaged

Bug description:
  For networked systems, for instance booting with an iSCSI root,
  dhclient writes an output file in the form of /run/net-.conf
  that contains data for other programs to consume. This allows, for
  instance, open-iscsi to get the right information and properly connect
  to the server to mount the root filesystem.

  It is common for DHCP servers to only provide a domain name value, and
  no search domains. In this case, isc-dhcp doesn't currently write
  DOMAINSEARCH, but people may wish to use short names to resolve things
  (such as in iSCSI server).

  In the not-initramfs dhclient-script, when domain_search isn't
  provided but domain_name is, domain_name is written to the search
  string. If both are provided, domain_search is written. The initramfs
  enter hook should do the same.
