* zebra: Modify southbound interface to pass `struct route_node`Donald Sharp2018-01-241-4/+5
| | | | | | | | | The route_node that we are working on is going to be interesting to the kernel_route_rib_pass_fail. So I am setting up the code to allow me to pass it. This will be done in a subsuquent commit. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

* zebra: Add one-shot thread to recheck speedDonald Sharp2018-01-111-0/+5
| | | | | | | | | | | | | | | | | | There are certain interfaces that when brought up and we receive the netlink notification about it, the speed of the interface is not set correctly. This creates a one-shot thread that will wait 15 seconds and then requery the speed and if it is different it will renotify the running daemons. The kernel should notify us on speed changes, unfortunately this is not done currently via a netlink message as you would think. As I understand it there is some in-fighting about the proper way to approach this issue and due to the way the kernel release cycle works we are a ways off from getting this fixed. This is a `hack` to make us work correctly while we wait for the true answer. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

* zebra: Implement call back for route install/delete success/failDonald Sharp2017-11-291-3/+13
| | | | | | | | | | | | | | | | | When a route is installed or deleted into the kernel allow a callback mechanism to handle the success/failure of the kernel call. This separation is to allow us to do these things: 1) In the future create a true pthread to handle route install/deletes. This way we can schedule these events in a smarter fashion 2) Allow us to use a common southbound api for route install and deletion. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
* zebra: rt_socket.c should not use SET_FLAGDonald Sharp2017-11-161-20/+1
| | | | | | | | | | | | | | | The SET_FLAG(nexthop->flags, NEXTHOP_FLAG_FIB) is already taken care of in zebra_rib.c. There is no need for this to be handled by rt_socket.c. rt_netlink.c does not do a SET_FLAG(nexthop->flags, NEXTHOP_FLAG_FIB) for route installation. Please note it does do it for a mpls labeled route installation, which will be fixed in a future commit. Remove some dead code from 2002 as well.

* zebra: deduplicate nexthopsDavid Lamparter2017-09-121-2/+2
| | | | | | | | | | | | | | | There exists situations where it is possible to have duplicate nexthops passed from a higher level protocol into zebra. This code notices this duplication of nexthops and marks the duplicates as DUPLICATE so we don't attempt to install it into the kernel. This is important on *BSD as I understand it because passing duplicate nexthops will cause the route to be rejected.

* zebra: increase maximum label stack depthRenato Westphal2017-08-221-10/+38
| | | | | | | | | | | | | | * Bump MPLS_MAX_LABELS from 2 to 16; * Adjust the static_nh_label structure and the mpls_label2str() function; * On OpenBSD, print an error message when trying to push more than one label at once (kernel limitation). While here, add support for MPLSv6 FTNs in OpenBSD. This is not the full package. We still can't pop multiple labels at once, or do things like swap a label and push other ones. We'll address that in the future. Signed-off-by: Renato Westphal <renato@opensourcerouting.org>

* *: simplify log message lookupQuentin Young2017-06-211-2/+2
| | | | | | | | | | | | | | | | log.c provides functionality for associating a constant (typically a protocol constant) with a string and finding the string given the constant. However this is highly delicate code that is extremely prone to stack overflows and off-by-one's due to requiring the developer to always remember to update the array size constant and to do so correctly which, as shown by example, is never a good idea.b The original goal of this code was to try to implement lookups in O(1) time without a linear search through the message array. Since this code is used 99% of the time for debugs, it's worth the 5-6 additional cmp's worst case if it means we avoid explitable bugs due to oversights...

* zebra: Refactor 'struct rib' to be 'struct route_entry'Donald Sharp2017-06-011-16/+16
| | | | | | | | | | The 'struct rib' data structure is missnamed. It really is a 'struct route_entry' as part of the 'struct route_node'. We have 1 'struct route_entry' per route src.
