parentnet: core: Add a UID field to struct sock. (diff)
net: core: add UID to flows, rules, and routes
- Define a new FIB rule attributes, FRA_UID_RANGE, to describe a range of UIDs. - Define a RTA_UID attribute for per-UID route lookups and dumps. - Support passing these attributes to and from userspace via rtnetlink. The value INVALID_UID indicates no UID was specified. - Add a UID field to the flow structures. Signed-off-by: Lorenzo Colitti <lorenzo@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
