* include: drop "netlink-private/netlink.h" and move declarationsThomas Haller2023-08-021-2/+0

* 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/+9
| | | | | Move all the declarations from "netlink-private/types.h" to places closer to where they are used.
* route: merge "include/netlink-private/tc.h" to lib/route/tc-api.hThomas Haller2023-08-011-1/+0
| | | | | It's a private header only for lib/route (libnl-route-3). We already have a similar header. Move the content to "lib/route/tc-api.h".
* route: move "include/netlink-private/route/tc-api.h" to lib/routeThomas Haller2023-08-011-1/+2
| | | | | | | | This header is entirely private to lib/route (libnl-route-3). Move the header there, it should not be used by anybody else. Note that libnl-route-3 exports symbols from this private header. That is ugly, make that clearer by adding comments.
* 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:cls: fix dangling pointers in to_clone() implementationsThomas Haller2022-03-041-1/+4
| | | | | | | | | | | rtnl_tc_clone() first does a shallow-copy (nl_data_clone()), and then calls the to_clone() implementation. We need the shallow-copy, because we want that by default all simple fields get cloned automatically. But it means, we *must* take care of all pointers in the to_clone() implementation, and must never return without fixing them. Otherwise we will do a double free. An early "return -NLE_NOMEM;" leaves the pointer unchanged, and two objects own the same data (double free and use-after-free says hello).
* license: fix and add SPDX license identifiers and drop license commentsThomas Haller2020-04-161-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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..\(-20..\|, 20..\)\?

* Move private header files to <netlink-private/*>Thomas Graf2013-01-241-4/+4
| | | | | | | This clarifies the seperation between public and private header files. Signed-off-by: Thomas Graf <tgraf@suug.ch>
* add fwmark mask supportA C2012-05-291-1/+30
| | | | | | The fw classifier allows a mask to be set, which is necessary for some complex shaping/firewall scenarios. The attached patch adds support for it to libnl.
* Unified TC APIThomas Graf2011-03-211-34/+44
| | | | | | | | Finally got rid of all the qdisc/class/cls code duplication in the tc module API. The API takes care of allocation/freeing the tc object specific data. I hope I got it right this time.
* Unified TC attributes interfaceThomas Graf2010-10-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | So far all common tc atttributes were accessed via specific functions, i.e. rtnl_class_set_parent(), rtnl_qdisc_set_parent(), rtnl_cls_set_parent() which implied a lot of code duplication. Since all tc objects are derived from struct rtnl_tc and these common attributes are already stored in there this patch removes all type specific functions and makes rtnl_tc_* attribute functions public. rtnl_qdisc_set_parent(qdisc, 10); becomes: rtnl_tc_set_parent((struct rtnl_tc *) qdisc, 10); This patch also adds the following new attributes to tc objects therefore removing them as tc specific attributes: - mtu - mpu - overhead This allows for the rate table calculations to be unified as well taking into account the new kernel behavior to take care of overhead automatically.
* - Reworked the classifier interface.Thomas Graf2009-09-021-73/+23
| | | | | | - Added initial ematch support - Added support for the basic classifier - Added support for the cgroup classifier
* Remove old line counting while dumpingThomas Graf2008-05-231-26/+12

* Remove obsolete nla_get_addr() and nla_get_data()Thomas Graf2008-05-141-2/+2
| | | | | | | | Replaces obsolete calls to nla_get_addr() and nla_get_data() with nl_addr_alloc_attr() respectively nl_data_alloc_attr(). Also fixes missing error handling while parsing routing multipath configuration.
* Thread-safe error handlingThomas Graf2008-05-141-15/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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!
