* route/route: support FIB lookups using rtnlTobias Waldekranz2022-03-111-0/+3
| | | | | | | Using the flnl_* family of functions to perform FIB lookups is rather limited. In particular, there seems to be no way of resolving the nexthop. By hooking into RTM_GETROUTE, a regular rtnl route object is returned instead.

* route/link: add RTNL_LINK_REASM_OVERLAPS statIlya Pronin2020-04-161-0/+1
| | | | | | | | | | | | | | | | | | The new stat exposes IPSTATS_MIB_REASM_OVERLAPS link stat. However, the original motivation for this change was fixing the issue with missing RX packets link stat. The regression was introduced in version 3.5.0 with commit 73c1d047, that added a new enum constant IPSTATS_MIB_REASM_OVERLAPS. Without this patch, IPSTATS_MIB_REASM_OVERLAPS is missing from map_stat_id_from_IPSTATS_MIB_v2 and is mapped by it to 0. This tricks inet6_parse_protinfo() into erroneously overwriting RTNL_LINK_RX_PACKETS stat, which happens to have value 0, when it tries to set IPSTATS_MIB_REASM_OVERLAPS. Fixes: 73c1d0479643 ('Sync linux headers to 4.19.66') https://github.com/thom311/libnl/pull/235

* route/qdisc: adjust API for 64 bit rate/ceil support for htb classThomas Haller2019-09-012-6/+13
| | | | | | | | | | | | | | | | - existing API/ABI must stay unchanged. We cannot change parameter types. Ad most we can add new variants that support 64 bit integers. - rtnl_tc_calc_txtime64() and rtnl_tc_calc_bufsize64() are trivial. We should not blow up the public API of libnl for such a thing. If the users needs it, they can just reimplement it. - getters should return an error code. Especially if the return type does not support encoding an error there. - don't add separate rs_rate64/rs_ceil64 field. Instead, extend the "rs_rate" field of "struct rtnl_ratespec" to 64 bits. It's internal API.
* Add 64bit rate/ceil support for htb classd0u92019-09-012-6/+6
| | | | | Htb class has already supported 64bit rate and ceil settings for times. Now, in this patch, we grant this ability to libnl library.
* xfrmi: return error code from getters for XFRM linksThomas Haller2019-09-011-2/+2
| | | | | | | | Returning the value directly as uint32_t does not leave room for an error code. E.g. we want to indicate to the caller whether the attribute is present or not (-NLE_NOATTR). Currenlty, the code is quite unforgiving and will just crash/assert against invalid arguments. In theory, we could also be more forgiving and return a error code if the link argument is invalid.
* xfrmi: introduce XFRM interfaces supportEyal Birger2019-09-011-0/+37
| | | | | | | XFRM interfaces were introduced in kernel 4.19. This commit adds link support for these interfaces. Signed-off-by: Eyal Birger <eyal.birger@gmail.com>

* route/act: return error code from act-vlan gettersThomas Haller2018-10-101-5/+5
| | | | | | Our API is unfortunately not consistent about this. However, in general, getters should aim to return an error code whether the attribute could be retrieved.

* lib/qdisc: avoid BUG() in "lib/route/qdisc/mqprio.c"Thomas Haller2018-10-091-1/+1
| | | | | | | | | | BUG() raises an assertion. It seems overly harsh. For example, rtnl_tc_data() can fail if we fail to allocate memory. Asserting against that, makes libnl3 not out-of-memory safe. Just return a regular error.

* Add support for cloning cgroup filter object.d0u92018-06-251-0/+2
| | | | | | | | | | | In this commit, we implement ematch_tree_clone(), which is basis of cgroup_clone() interface. The whole ematch tree is deep-copied except the e_ops filed. Also, a new unit test is added for testing the interface, which named as check-ematch-tree-clone.c located in tests directory. https://github.com/thom311/libnl/pull/176
* neigh: add get/set functions for NEIGH_ATTR_MASTERTobias Jungel2018-06-251-0/+3

* route/class: add new api rtnl_class_get_by_parent()d0u92018-04-111-0/+3
| | | | | | | | This function searches a class cache previously allocated with rtnl_class_alloc_cache() and searches for a class matching the interface index and parent qdisc. https://github.com/thom311/libnl/pull/185

* route: rename rtnl_cls_cache_set_tcm_params() and fix symbol versioningThomas Haller2018-01-181-1/+1
| | | | | | | | | After rethinking, "tcm_params" doesn't seem like a good name. Change it to "tc_params". Also, an already released section in the linker file must never be modified. It defeats the purpose of symbol versioning. Move the symbol to the right section.
* Add new function for setting ifindex and parent of a classifier cache.d0u92018-01-181-0/+2
| | | | | | | It is not good to give classifier cache users only one chance to set interface index and parent handle when allocte new cache. Sometimes we want to reuse classifier cache to reduce the overhead of allocating new memory everytime a new cache is created.
* route: mark data argument for rtnl_netem_set_delay_distribution_data() as constThomas Haller2018-01-161-1/+1

* route: add separate function to set netem qdisc delay distributionSteffen Vogel2017-12-201-0/+1
| | | | | | | | | A new function rtnl_netem_set_delay_distribution_data() has been added to allow the user to pass the delay distribution directly without loading it from a file. In conjunction with the maketable code (see iproute2 / NISTnet) this can be used to generate and load custom delay distributions on the fly.

* route: Add support for ttl propagation in MPLS routesDavid Ahern2017-08-181-0/+3
| | | | | | | Add support for RTA_TTL_PROPAGATE attribute on a per-route basis. Used to enable/disable TTL propagation at LSP egress. Signed-off-by: David Ahern <dsahern@gmail.com>
* route: Add support for MPLS address familyDavid Ahern2017-08-181-0/+6
| | | | | | | | | | | | | | | | | Add support for route in MPLS family. New attributes: - RTA_NEWDST - label stack for a nexthop - RTA_VIA - nexthop address (e.g., IPv4 or IPv6) Other changes required: - scope has to be universe for MPLS routes so fixup rtnl_route_guess_scope - priority attribute can not be set for MPLS. Change rtnl_route_parse to not set the attribute by default for AF_MPLS. - table attribute should not be set unless something other than the default table. For MPLS this attribute can not be set. '/' is the separator in label stacks for consistency with iproute2. Signed-off-by: David Ahern <dsahern@gmail.com>
* rule: change API for setting/getting l3mdev rule propertyThomas Haller2017-05-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | - for rtnl_rule_set_l3mdev(), also allow unsetting the l3mdev field. In practice, kernel only allows for two options: either omit tb[FRA_L3MDEV] or set it to 1. As such, rtnl_rule_set_l3mdev() allows for both of these. In principle the setter could get extended to set other values. Such values are reserved. - for rtnl_rule_get_l3mdev() also return an error code. I think it is appropriate to mix value and negative error code, as long as the range of values cannot overlap with error codes. Arguably, the outcome is a bit awkward, as the function now is expected to return -NLE_MISSING_ATTR or 1. So, the best check is probably if (rtnl_rule_get_l3mdev(r) > 0) { ... } The reason for this change is that libnl should expose the netlink API without coercing uint8 to boolean. That way, future changes in kernel don't require update to libnl3. Signed-off-by: Thomas Haller <thaller@redhat.com>
* rule: Add support for l3mdev in FIB rulesDavid Ahern2017-05-121-0/+2
| | | | | | | | | | | | | | | | | | Add support for the l3mdev option in FIB rules. If l3mdev is set then the lookup is directed to the table associated with the l3mdev (e.g., VRF) device. If the l3mev attribute is set the table id is not, so update the table id attribute to make sure r_table is non-0. iproute2 shows the rule as: 1000: from all lookup [l3mdev-table] where [l3mdev-table] infers the dynamic nature of the table id. Keep that notation for libnl. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: Thomas Haller <thaller@redhat.com>
