* net: core: add UID to flows, rules, and routesLorenzo Colitti2017-05-231-2/+72
| | | | | | | | | | | | | | | | | | - 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. [Backport of net-next 622ec2c9d52405973c9f1ca5116eb1c393adfc7d] Bug: 16355602 Change-Id: I7e3ab388ed862c4b7e39dc8b0209d977cb1129ac Signed-off-by: Lorenzo Colitti <lorenzo@google.com> Signed-off-by: David S.

* fib_rules: fix fib rule dumps across multiple skbsWilson Kok2016-08-261-2/+5
| | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 41fc014332d91ee90c32840bf161f9685b7fbf2b ] dump_rules returns skb length and not error. But when family == AF_UNSPEC, the caller of dump_rules assumes that it returns an error. Hence, when family == AF_UNSPEC, we continue trying to dump on -EMSGSIZE errors resulting in incorrect dump idx carried between skbs belonging to the same dump. This results in fib rule dump always only dumping rules that fit into the first skb. This patch fixes dump_rules to return error so that we exit correctly and idx is correctly maintained between skbs that are part of the same dump.
