* lib: Add hash and use const a bit more intelligentlyQuentin Young2018-04-061-1/+14
| | | | | | | | | | | This commit adds code to notify the compiler that we will not be changing the arguments to nexthop2str and we expect thre return to be treated the same. Additionally we add some code to allow nexthops to be hashed to be used in a hash. Signed-off-by: Quentin Young <qlyoung@cumulusnetworks.com>
* *: use C99 standard fixed-width integer typesQuentin Young2018-03-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | The following types are nonstandard: - u_char - u_short - u_int - u_long - u_int8_t - u_int16_t - u_int32_t Replace them with the C99 standard types: - uint8_t - unsigned short - unsigned int - unsigned long - uint8_t - uint16_t - uint32_t Signed-off-by: Quentin Young <qlyoung@cumulusnetworks.com>
* lib: Add nexthop-group cliDonald Sharp2018-03-141-0/+51
| | | | | | | | | | | | | | | | | | | | Add a nexthop-group cli: nexthop-group NAME nexthop A nexthop B nexthop C ! This will allow interested parties to hook into the cli for nexthops. Users can add callback functions for add/delete of a nexthop group as well as add/delete of each individual nexthop. Future work( PBR and static routes ) will take advantage of this.

* lib: fix a64448ba, invalid NULL->num_labelsVincent JARDIN2017-10-091-1/+1
| | | | | | | | | | | | We should assume match OK only when neither nhl1 and neither nhl2 are NULL. If both are NULL, it means match NOK. Clang Warning: Access to field 'num_labels' results in a dereference of a null pointer (loaded from variable 'nhl1') Signed-off-by: Vincent Jardin <vincent.jardin@6wind.com>
* zebra: deduplicate nexthopsDavid Lamparter2017-09-121-0/+33
| | | | | | | | | | | | | | | 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.

* *: make consistent & update GPLv2 file headersDavid Lamparter2017-05-151-4/+3
| | | | | | | | | | | The FSF's address changed, and we had a mixture of comment styles for the GPL file header. (The style with * at the beginning won out with 580 to 141 in existing files.) Note: I've intentionally left intact other "variations" of the copyright header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

* zebra: labeled unicast handlingDon Slice2017-04-061-0/+22
| | | | | | | | | Support install of labeled-unicast routes by a client. This would be BGP, in order to install routes corresponding to AFI/SAFI 1/4 (IPv4) or 2/4 (IPv6). Convert labeled-unicast routes into label forwarding entries (i.e., transit LSPs) when there is a static label binding. Signed-off-by: Don Slice <dslice@cumulusnetworks.com>

* *: split & distribute memtypes and stop (re|ab)using lib/ MTYPEsDavid Lamparter2016-09-191-0/+2
| | | | | | | | | | | | | | | | | | | This is a rather large mechanical commit that splits up the memory types defined in lib/memtypes.c and distributes them into *_memory.[ch] files in the individual daemons. The zebra change is slightly annoying because there is no nice place to put the #include "zebra_memory.h" statement. bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the library for its own use. This is bad practice and would break when the memtype are made static.
