New Revision: 362465
URL: https://svnweb.freebsd.org/changeset/base/362465
Log:
MFC r362289:
When converting the static arrays to mallocarray() in r356621 I missed
one place where we now need to multiply the size of the struct with the
number of entries. This lead to problems when restarting user space
daemons, as the cleanup was never properly done, resulting in MRT_ADD_VIF
EADDRINUSE.
Properly zero all array elements to avoid this problem.
