| 0000122 | Pgpool-II | Bug | public | 2014-11-25 20:48 | 2015-04-28 18:06 |

| Summary | 0000122: pgpool-II 3.4.0 - if_up_cmd and if_down_cmd $_IP_$ substitution is too optimistic | ||||
| Description | I 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 Reproduce | pgpool.conf settings: delegate_IP = '192.0.2.10' 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 192.0.2.5/24 brd 192.0.2.255 scope global eth0 valid_lft forever preferred_lft forever inet 192.0.2.10/32 scope global eth0 <------------ valid_lft forever preferred_lft forever | ||||
| Additional Information | If I hard-code the IP address (if_up_cmd = 'sudo /bin/ip addr add 192.0.2.10/24 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: http://git.postgresql.org/gitweb/?p=pgpool2.git;a=blob;f=src/watchdog/wd_if.c;h=8d3dc231485501c9107ef1f00658b6a9ec0a797e;hb=c07ce977305e06e7948e59e0eef152dcd6103365#l174 | ||||
