net: fib_rules: Correctly set table field when table number exceeds 8 bits

In 709772e6e06564ed94ba740de70185ac3d792773, RT_TABLE_COMPAT was added to allow legacy software to deal with routing table numbers >= 256, but the same change to FIB rule queries was overlooked. Signed-off-by: Jethro Beekman Signed-off-by: David S. Miller

net: fib_notifier: propagate extack down to the notifier block callback

2019-10-04T18:10:56+00:00

Since errors are propagated all the way up to the caller, propagate possible extack of the caller all the way down to the notifier block callback. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

net: fib_notifier: propagate possible error during fib notifier registration

2019-10-04T18:10:56+00:00

Unlike events for registered notifier, during the registration, the errors that happened for the block being registered are not propagated up to the caller. Make sure the error is propagated for FIB rules and entries. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

net: fib_notifier: make FIB notifier per-netns

2019-10-04T18:10:55+00:00

Currently all users of FIB notifier only cares about events in init_net. Later in this patchset, users get interested in other namespaces too. However, for every registered block user is interested only about one namespace. Make the FIB notifier registration per-netns and avoid unnecessary calls of notifier block for other namespaces.
