From: Eric Dumazet <eduma...@google.com>
David Ahern added a vif field in the a4 part of inetpeer_addr struct.
This broke IPv4 TCP fast open client side and more generally tcp metrics
cache, because inetpeer_addr_cmp() is now comparing two u32 instead of
one.
inetpeer_set_addr_v4() needs to properly init vif field, otherwise
the comparison result depends on uninitialized data.
Fixes: 192132b9a034 ("net: Add support for VRFs to inetpeer cache")
