[PATCH] ipvsadm: init svc in ipvs_get_service

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



ipvs_get_service() needs to init the allocated svc
for the non-netlink case due to the used CHECK_COMPAT_SVC
macro that includes pe_name[0] check in CHECK_PE. Use
calloc to avoid reading random data.

For the netlink case use malloc as before.
