* zebra: Modify southbound interface to pass `struct route_node`Donald Sharp2018-01-241-3/+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/+1
| | | | | | | | | | | | | | | | | | 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 Sharp2017-11-291-2/+30
| | | | | | | | | | | | | | | | | 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: Note about functionality in rt.hDonald Sharp2017-11-161-0/+11

* zebra: Refactor 'struct rib' to be 'struct route_entry'Donald Sharp2017-06-011-1/+1
| | | | | | | | | | 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. As such 1 route node can have multiple route entries if multiple protocols attempt to install the same route. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>

* [zebra/solaris] Interface state fixups for Solaris.paul2006-01-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2006-01-25 Paul Jakma <paul.jakma@sun.com> * (general) More solaris PF_ROUTE hacks. The IFF_UP mangling for solaris was incomplete on the PF_ROUTE side. fix it. This changeset generally uglifies things. For some future work I'd like to see the state changes seperated out from the details of the code. Differences between systems might then be slightly easier to implement without convoluted hacks. Changes should be specific to Solaris mostly, however also tested on FreeBSD 6. * if_ioctl_solaris.c: (interface_list_ioctl) ignore ~IFF_UP interfaces, we'll hear about them when/if interface goes up through NEWADDR. Update flags explicitely at end of it to kick mangling. * ioctl_solaris.c: (if_mangle_up) removed to interface.c, in kind. (lifreq_set_name) more convenient to take the string, than the ifp. (if_get_flags_direct) new convenience function, returns the actual flags. Used during bootstrap in if_ioctl_solaris.c to peek at flags of logical interfaces to see whether or not to ignore them. (if_get_flags) ENXIO means it's gone, poke out IFF_UP and kick flags update. (if_{un,}set_flags) flags argument should be 64bit. * ioctl.{c,h}: flags argument should be 64bit. * interface.h: Add a 'primary_state' flag to struct zebra_if on SUNOS_5. Export if_flags_update. * interface.c: (if_flags_mangle) moved over in kind from ioctl_solaris.c. Nasty kludge to try get IFF_UP right, as much as is possible. Also keep track of the actual IFF_UP value for the primary interface, so we can know when the ifp must be deleted. (if_flags_update) Take a new interface flags value, apply it to the interface, and take whatever actions are required due to flag transitions. (if_refresh) flag state change logic is moved out to previous. Just call if_get_flags, which will end up using previous to effect the update of flags. (if_flag_dump_vty) IFF_IPV{4,6} aren't interesting, VIRTUAL and NOXMIT are though. * kernel_socket.c: (ifm_read) Down->Down transitions shouldn't create ifp, for non-IFANNOUNCE systems. Use if_flags_update to update flags. flag transition logic is now handled automatically through if_flags_update. (ifam_read) Better to call if_refresh *after* adding connected addresses, as connected count affects IFF_UP on IFF_UP-mangled systems. On Solaris, Up->Down due to DELADDR means we need to delete the ifp - the IFINFO might already have been and gone. * rt.h: include other dependent headers.
