[PATCH v4 net 0/2] net: sched: initialize struct tc_ife to fix kernel-infoleak

[Ranganath V N <vnranganath.20@gmail.com>]

This series addresses the uninitialization of the struct which has
2 bytes of padding. And copying this uninitialized data to userspace
can leak info from kernel memory.

This series ensures all members and padding are cleared prior to
begin copied.

This change silences the KMSAN report and prevents potential information
leaks from the kernel memory.
