State Changed From-To: open->closed Thanks for your excellent analysis of the problem! I've applied the patch to -current, and barring any problems, I'll try to get it MFC'd for 4.4. |
In /etc/rc, special care is taken so that portmap will be automatically enabled if either amd, nfs or nis enabled: chkdepend amd amd_enable portmap portmap_enable chkdepend NFS nfs_server_enable portmap portmap_enable chkdepend NIS nis_server_enable portmap portmap_enable chkdepend NIS nis_client_enable portmap portmap_enable Thanks to these lines, variable ${portmap_enable} will be set to "YES" if needed. However, /etc/rc later loads /etc/rc.firewall, which unconditionally reloads /etc/defaults/rc.conf (and /etc/rc.conf, if exists): if [ -r /etc/defaults/rc.conf ]; then . /etc/defaults/rc.conf source_rc_confs elif [ -r /etc/rc.conf ]; then . /etc/rc.conf fi Thus, unless user specifically set ${portmap_enable} to "YES" in /etc/rc.conf, ${portmap_enable} will be reset to "NO" in /etc/defaults/rc.conf. Later on, /etc/rc invokes network_pass2() (which defined in /etc/rc.network) but portmap won't be run because ${portmap_enable} has been reset to "NO". Fix: In /etc/rc.firewall, don't reload /etc/rc.conf nor /etc/defaults/rc.conf if they are already loaded. /etc/rc.firewall6 already cares this so the same approach can be applied to /etc/rc.firewall as well. Patch is as follows: How-To-Repeat: Create /etc/rc.conf as follows: nfs_server_enable="YES" And reboot the system. During bootup, rc shows: DEPENDENCY NOTE: portmap_enable will be enabled to support NFS However, % ps ax | grep portmap produces nothing.
