* include: drop "netlink-private/netlink.h" and move declarationsThomas Haller2023-08-021-2/+2

* all: cleanup includes and use "nm-default.h"Thomas Haller2023-08-021-1/+4

* include: split and drop "netlink-private/types.h"Thomas Haller2023-08-021-0/+1
| | | | | Move all the declarations from "netlink-private/types.h" to places closer to where they are used.
* nl-aux: add "include/nl-aux-{core,route}" headersThomas Haller2023-07-311-1/+2
| | | | | | | | | | | | | | | | | | | We have "include/netlink-private/netlink.h", which is private API used internally. However, it's confusing where "include/netlink-private/netlink.h" can be used. For example, it contains some "libnl-route-3.so" specific extensions like "link_lookup()", hence you would think that it can only be used with libraries that also use "libnl-route-3.so". Well, since it's a header, you actually can also use it for example under "lib/xfrm/", you couldn't just use those declarations because they are implemented and accessible only under "lib/route/" In a first step to clean this up, and move helper to separate headers, add "include/nl-aux-{core,route}" headers with certain clear usage. Clear in the sense who may use those headers, and what the implementation of those headers may use.
* lib: use _nl_{init,exit} instead of __{init,exit}Thomas Haller2023-07-281-2/+2
| | | | | We should have things with "nl" prefix in our headers. Also, netlink-private/netlink.h is not header-only, preferably header-only stuff is in netlink-private/utils.h
* route/route: don't report failure when we receive a route in rtnl_route_lookup()Thomas Haller2022-03-111-6/+6
| | | | | | | | | - when we received a route and set `*result`, we should not return an error. That means, ignore the result of wait_for_ack(). - use _nl_auto* cleanup macros. - move new symbols to linker version for the upcoming release.
* route/route: support FIB lookups using rtnlTobias Waldekranz2022-03-111-0/+27
| | | | | | | 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.
* license: fix and add SPDX license identifiers and drop license commentsThomas Haller2020-04-161-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This also fixes a few wrong SPDX license identifiers, where the original license comment indicates GPL-2.0-only. This is not done manually, but by running the following script: --- #!/bin/bash # Tool to drop license comments, adding SPDX license identifiers, while preserving # copyright comments. The point is not to manually do this task, but perform some # hacked up string replacement. _cp() { /bin/cp "$@" } _cat() { /bin/cat "$@" } in_file() { local T=$(mktemp) _cp -f "$1" "$T" _cat "$T" rm -f "$T" } out_file() { local T=$(mktemp) _cat - > "$T" _cp -f "$T" "$1" rm -f "$T" } join() { _cat "$@" | awk '{ printf("%s#x#", $0)}' } unjoin() { _cat - | sed 's/#x#/\n/g' } files_all() { git ls-files | grep -v '\.png$' | grep -v '^include/linux-private/' } adjust() { NEWLINES='\(#x#\)\+' COPYRIGHTS='\(\( \* Copyright (c) 20..\(-20..\|, 20..\)\?

* route: Add support for MPLS address familyDavid Ahern2017-08-181-0/+1
| | | | | | | | | | | | | | | | | 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>
* Move private header files to <netlink-private/*>Thomas Graf2013-01-241-1/+1

| | | | Signed-off-by: Thomas Graf <tgraf@suug.ch>
* Documentation updatesThomas Graf2011-03-211-1/+2
| | | | Mostly killing doxygen warnings, some doc updates to caching
* Add internal wait_for_ack() which only waits for ACK if !NL_NO_AUTO_ACKThomas Graf2008-10-201-2/+2
| | | | | This changeset ensures that internal code properly synchronizes to ACKs if ACKs are enabled and otherwise return immediately.
* Allow parser callbacks to return NL_OK, NL_SKIP, NL_EXITThomas Graf2008-05-151-5/+1
| | | | Obsoletes internal P_ACCEPT/P_IGNORE
* Rename struct nl_handle to struct nl_sockThomas Graf2008-05-151-12/+10
| | | | | | | | The idea of a common handle is long revised and only misleading, nl_handle really represents a socket with some additional action handlers assigned to it. Alias for nl_handle is kept for backwards compatibility.
* Thread-safe error handlingThomas Graf2008-05-141-28/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order for the interface to become more thread safe, the error handling was revised to no longer depend on a static errno and error string buffer. This patch converts all error paths to return a libnl specific error code which can be translated to a error message using nl_geterror(int error). The functions nl_error() and nl_get_errno() are therefore obsolete. This change required various sets of function prototypes to be changed in order to return an error code, the most prominent are: struct nl_cache *foo_alloc_cache(...); changed to: int foo_alloc_cache(..., struct nl_cache **); struct nl_msg *foo_build_request(...); changed to: int foo_build_request(..., struct nl_msg **); struct foo *foo_parse(...); changed to: int foo_parse(..., struct foo **); This pretty much only leaves trivial allocation functions to still return a pointer object which can still return NULL to signal out of memory. This change is a serious API and ABI breaker, sorry!
* Route cache supportThomas Graf2008-05-051-2/+15
| | | | | | This changesets adds the possibility to fill a nl_cache with the contents of the route cache. It also adds the possibility to limit route caches to certain address families.
* Big routing code rework (API/ABI BREAK!)Thomas Graf2008-04-291-265/+9
| | | | | | | | | | Adds all missing routing attributes and brings the routing related code to a working state. In the process the API was broken several times with the justification that nobody is using this code yet. The changes include new example code which is also a prototype for how plain CLI tools could look like to control routes.
* Represent default route with destination address length zeroThomas Graf2007-12-191-6/+9
| | | | | | | | | | So far the destination address for default routes was NULL which complicated the handling of routes in general. By assigning a address of length zero they can be compared to each other. This allows the cache manager to properly handle default routes.
* Fix memory leak when parsing netlink messages into cachesThomas Graf2007-12-171-3/+4
| | | | The reference created by the parsers was never given back.
* Export interface to define cachesThomas Graf2007-09-171-2/+1
| | | | | | | | | | This interface was internal so far which required all code defining caches to be compiled with the sources available. In order to simplify the interface, the co_msg_parser prototype was changed to take the struct nl_parser_param directly instead of a void *. It used to be void * because the co_msg_parser was directly passed as the NL_CB_VALID callback function.
