Sponsored for development release (cosmic). I'll start the SRU, beginning of next week. That will give cosmic the time to go through build, autopkgtest, ... and get "Fix Released" by the time we are starting the SRU.

As a result, the search list is ignored in the clients. [Test case] * Install an ubuntu machine that uses iscsi as root, and does not use systemd-resolvd. * Prepare the dhcp server to provide the search list to its clients. For instance, in dnsmasq: dhcp-option=option:domain-search,canonical.com * Boot the machine and check the content of /etc/resolv.conf - if domainsearch is present, the search list will be ignored: root@iscsi-xenial:/home/ubuntu# ping -c1 golem ping: unknown host golem root@iscsi-xenial:/home/ubuntu# strace ping -c1 golem 2>&1 | grep golem execve("/bin/ping", ["ping", "-c1", "golem"], [/* 19 vars */]) = 0 sendto(4, "_(\1\0\0\1\0\0\0\0\0\0\5golem\0\0\1\0\1", 23, MSG_NOSIGNAL, NULL, 0) = 23 recvfrom(4, "_(\201\203\0\1\0\0\0\0\0\0\5golem\0\0\1\0\1", 1024, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.122.1")}, [16]) = 23 write(2, "ping: unknown host golem\n", 25ping: unknown host golem - if search is present, the search list will be used: root@iscsi-xenial:/home/ubuntu# ping -c1 golem PING golem.canonical.com (91.189.89.199) 56(84) bytes of data. 64 bytes from golem.canonical.com (91.189.89.199): icmp_seq=1 ttl=57 time=63.7 ms --- golem.canonical.com ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 63.735/63.735/63.735/0.000 ms root@iscsi-xenial:/home/ubuntu# strace ping -c1 golem 2>&1 | grep golem execve("/bin/ping", ["ping", "-c1", "golem"], [/* 19 vars */]) = 0 sendto(4, "\1\\\1\0\0\1\0\0\0\0\0\0\5golem\tcanonical\3com"..., 37, MSG_NOSIGNAL, NULL, 0) = 37 recvfrom(4, "\1\\\201\200\0\1\0\1\0\0\0\0\5golem\tcanonical\3com"..., 1024, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.122.1")}, [16]) = 53 write(1, "PING golem.canonical.com (91.189"..., 145PING golem.canonical.com (91.189.89.199) 56(84) bytes of data. 64 bytes from golem.canonical.com (91.189.89.199): icmp_seq=1 ttl=57 time=63.5 ms write(1, "--- golem.canonical.com ping sta"..., 157--- golem.canonical.com ping statistics --- [Regression potential] * The change is minor (a string replacement) and it's currently not working. * Any possible regression would involve continuing to break DNS resolution.
