It seems IPVS is busted in case of memory allocation error in
__ip_vs_control_init()
IPVS deinits its "struct netns_ipvs" space, but something (in IPVS) uses
it after free.
__ip_vs_init() seems to be called before ip_vs_init() completes
correctly. We then keep in net->ipvs a pointer to some freed memory.
Commit 14e405461e664b7 did some changes in this area
Simon, any idea ?
