Summary0000122: pgpool-II 3.4.0 - if_up_cmd and if_down_cmd $_IP_$ substitution is too optimistic
DescriptionI have pgpool-II 3.4.0 installed along with virtual IP address control, via sudo and the ip command.

Whenever pgpool brings up the the virtual IP address, "$_IP_$" will be substituted until the next whitespace, rather than only the pattern itself.

This results in a wrong prefix length (/32) being configured, when the IP is brought up.

Steps To Reproducepgpool.conf settings:

delegate_IP = ''
ifconfig_path = '/usr/bin'
if_up_cmd = 'sudo /bin/ip addr add $_IP_$/24 dev eth0'
if_down_cmd = 'sudo /bin/ip addr del $_IP_$/24 dev eth0'

Start pgpool-II, and check the the network interface after the VIP was brought up:

ip addr show dev eth0

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether XX:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff
    inet brd scope global eth0
       valid_lft forever preferred_lft forever
    inet scope global eth0 <------------
       valid_lft forever preferred_lft forever
Additional InformationIf I hard-code the IP address (if_up_cmd = 'sudo /bin/ip addr add dev eth0'), pgpool-II brings the prefix up correctly (with a prefix length of /24 rather than /32).

The problem is probably to be found within the exec_ifconfig function of src/watchdog/wd_if.c:;a=blob;f=src/watchdog/wd_if.c;h=8d3dc231485501c9107ef1f00658b6a9ec0a797e;hb=c07ce977305e06e7948e59e0eef152dcd6103365#l174
