Aliases are essential information for working with kernel modules. Netfilter
subsystem will request for ipt_hashlimit and ip6t_hashlimit respectively when
called with
xt_request_find_match(NFPROTO_IPV{4,6}, "hashlimit", 1)
The kernel __request_module() will then invoke user mode modprobe to load them
/sbin/modprobe -q -- ipt_hashlimit
/sbin/modprobe -q -- ip6t_hashlimit
where ipt_hashlimit and ip6t_hashlimit are aliases of xt_hashlimit
The patch depends on another patch in the build system to restore alias info
to kernel modules.
Yousong Zhou (6):
kmodloader: remove redundant glob wildcard char
kmodloader: log to kmsg when loading directories of modules
kmodloader: modprobe: skip possible command line arguments
kmodloader: fix out-of-bound access when parsing .modinfo
kmodloader: add module alias awareness
kmodloader: make insert_module() idempotent

applied it with minor patch 5 adjustments for ubox (different version ?
) and no more warning and some debugging on kmodloader (virtual machine
tested)
