- Add nm-dont-overwrite-resolv-conf.patch: Fix NetworkManager overwriting /etc/resolv.conf (bsc#960153, bsc#1021665).

Please not that current build of Leap 42.3 has NetworkManager-1.0.12-6.5.x86_64, which also contains the above-mentioned patch: Mo Feb 20 2017 sckang@suse.com - Add nm-dont-overwrite-resolv-conf.patch: Fix NetworkManager overwriting /etc/resolv.conf (bsc#960153, bsc#1021665).

Using NetworkManager with a router (Fritz box) providing DHCP service for DNS configuration. rpms: sysconfig-netconfig-0.84.1-2.1.x86_64 sysconfig-0.84.1-2.1.x86_64 Manually setting the dns line in resolv.conf as a workaround helps as a temporary fix: nameserver 85.214.20.141 -- You are receiving this mail because: You are on the CC list for the bug.

With NM 1.8, it writes this config file: # grep -v '^#' /var/lib/NetworkManager/dhclient-wlp58s0.conf option rfc3442-classless-static-routes code 121 = array of unsigned integer 8; option rfc4833-tz-posix-string code 100 = string; option rfc4833-tz-name code 101 = string; send host-name "tjmaciei-mobl1"; # added by NetworkManager option rfc3442-classless-static-routes code 121 = array of unsigned integer 8; option ms-classless-static-routes code 249 = array of unsigned integer 8; option wpad code 252 = string; request; # override dhclient defaults also request subnet-mask; also request broadcast-address; also request routers; also request rfc3442-classless-static-routes; also request ms-classless-static-routes; also request static-routes; also request wpad; also request ntp-servers; Whereas the pre-update NM (1.6.2) wrote it like this: # grep -v '^#' /.snapshots/973/snapshot/var/lib/NetworkManager/dhclient-wlp58s0.conf option rfc3442-classless-static-routes code 121 = array of unsigned integer 8; option rfc4833-tz-posix-string code 100 = string; option rfc4833-tz-name code 101 = string; require subnet-mask; timeout 60; retry 60; reboot 10; select-timeout 5; initial-interval 2; send host-name "tjmaciei-mobl1"; # added by NetworkManager option rfc3442-classless-static-routes code 121 = array of unsigned integer 8; option ms-classless-static-routes code 249 = array of unsigned integer 8; option wpad code 252 = string; request; # override dhclient defaults also request subnet-mask; also request broadcast-address; also request routers; also request rfc3442-classless-static-routes; also request interface-mtu; also request host-name; also request domain-name; also request domain-search; also request domain-name-servers; also request nis-domain; also request nis-servers; also request nds-context; also request nds-servers; also request nds-tree-name; also request netbios-name-servers; also request netbios-dd-server; also request netbios-node-type; also request netbios-scope; also request ntp-servers; also request ms-classless-static-routes; also request static-routes; also request wpad; dhclient is dhcp-client 4.3.3.P1-5.2 and hasn't changed for a month.

http://bugzilla.opensuse.org/show_bug.cgi?id=1047004 http://bugzilla.opensuse.org/show_bug.cgi?id=1047004#c13 --- Comment #13 from Thiago Macieira --- As far as I can tell, it's an upstream bug. NM will try to merge the settings from /etc/dhclient.conf, which as supplied by OpenSUSE contains: request subnet-mask, broadcast-address, routers, rfc3442-classless-static-routes, interface-mtu, host-name, domain-name, domain-search, domain-name-servers, nis-domain, nis-servers, nds-context, nds-servers, nds-tree-name, netbios-name-servers, netbios-dd-server, netbios-node-type, netbios-scope, ntp-servers; The NM parser will get only the *last* line containing "request" and will not do continuations. That's why my generated file had also request subnet-mask; also request broadcast-address; also request routers; but none of the others. WORKAROUND UNTIL UPSTREAM FIX: merge the dhclient.conf request line into one: request subnet-mask, broadcast-address, routers, rfc3442-classless-static-routes, interface-mtu, host-name, domain-name, domain-search, domain-name-servers, nis-domain, nis-servers, nds-context, nds-servers, nds-tree-name, netbios-name-servers, netbios-dd-server, netbios-node-type, netbios-scope, ntp-servers; (no line breaks!) -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1047004 http://bugzilla.opensuse.org/show_bug.cgi?id=1047004#c16 --- Comment #16 from Jonathan Kang --- For the request entry supplied by openSUSE: # Request several well known/usefull dhcp options. request subnet-mask, broadcast-address, routers, rfc3442-classless-static-routes, interface-mtu, host-name, domain-name, domain-search, domain-name-servers, nis-domain, nis-servers, nds-context, nds-servers, nds-tree-name, netbios-name-servers, netbios-dd-server, netbios-node-type, netbios-scope, ntp-servers; # rfc4833-tz-posix-string, rfc4833-tz-name; NM will parse these line by line. But the third line of the request entry starts with word "interface", which leads NM thinking it's a "interface" keyword (something like: interface "ep0" { blabla }). In this scenario, NM fails to parse the rest in request entry and this is exactly the cause of this bug. This issue is introduced by commit d405cfd9. I'll prepare a patch and send it to upstream for review. -- You are receiving this mail because: You are on the CC list for the bug.

Hello, this same bug is now happening when upgrading from Leap 42.3 to 15.0.

Is it the same issue as this one? If yes, does the workaround in comment#13 work for you? -- You are receiving this mail because: You are on the CC list for the bug.
