>Description:
The lines below show the conflicts in this ports ioctls. Ifconfig cores from a SIGBUS because the GIFGOPTS was being interpreted incorrectly by wanpipe, and smashed the stackframe of gif_status() in ifconfig/ifgif.c
usr/ports/misc/wanpipe/work/wanpipe-3.3.1/include:
wanpipe_snmp.h:# define SIOC_WANPIPE_SNMP _IOWR('i', 100, struct ifreq)
wanpipe_snmp.h:# define SIOC_WANPIPE_SNMP_IFSPEED _IOWR('i', 101, struct ifreq)
wanrouter.h:# define SIOC_WANPIPE_PIPEMON _IOWR('i', 150, struct ifreq) /* get monitor statistics */
wanrouter.h:# define SIOC_WANPIPE_DEVICE _IOWR('i', 151, struct ifreq) /* set generic device */
wanrouter.h:# define SIOC_WANPIPE_DUMP _IOWR('i', 153, struct ifreq) /* get memdump string (GENERIC) */
/usr/include:
netinet6/in6_var.h:#define SIOCSIFPREFIX_IN6 _IOW('i', 100, struct in6_prefixreq) /* set */
netinet6/in6_var.h:#define SIOCGIFPREFIX_IN6 _IOWR('i', 101, struct in6_prefixreq) /* get */
net/if_gif.h:#define GIFGOPTS _IOWR('i', 150, struct ifreq)
net/if_gif.h:#define GIFSOPTS _IOW('i', 151, struct ifreq)
>How-To-Repeat:
Build the wanpipe port [ requires a little manual intervention ] and install it on a machine with a Sangoma A10[124] board.
Configure the ports, and load modules with "wanrouter start".
After this, ifconfig faults when it queries any of the wanpipe interfaces.
>Fix:
Change the ioctl values in the wanpipe header files is step one.
A real 'fix' would involve an "ioctl value registry".
