* 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..\(-20..\|, 20..\)\?

* Fix for cgroup filter addition problem.d0u92018-01-231-0/+1
| | | | | | | | | | Currently, due to the incomplete netlink datagram sent by libnl, cgroup filter addition is not fully functional. The datagram generated by `tc` command includes an empty attribute section, which is stripped off in the libnl counterpart. In this commit, a new `interface nla_nest_end_keep_empty()` is added. This function closes attribute without stripping off empty attribute.
* nl: add "const" specifier for nla_policy argument of parse functionsThomas Haller2017-10-091-2/+2
| | | | | | | | | | | Adding const to a function argument is generally not an API break (at least, if the argument is a struct, like in this case). Usually we declare the policy as static variables. The user should be able to mark them as "const", so that the linker makes the policy array read-only. Adjust the API to allow for that. Signed-off-by: Thomas Haller <thaller@redhat.com>
* include: don't include kernel headers in public libnl3 headersThomas Haller2017-03-021-0/+2
| | | | | | | | | | | | | | | | | It would be desirable not to include kernel headers in our public libnl3 headers. As a test, remove all those includes, and fix compilation by explicitly including the kernel headers where needed. In some cases, that requires forward declaration for kernel structures, as we use them as part of our own headers. Realistically, we cannot drop those includes as it probalby breaks compilation for users that expect to get a certain kernel header when including a libnl3 header. So, this will not be done and the includes will be restored in the next commit. Do this step to show how it would be and to verify that we could build with such a change. The reason not to do this is backward compatibility (at compile-time).
* lib: add type casting for nla_for_each_nested macroPrzemyslaw Szczerbik2016-02-251-1/+1
| | | | | | | | | | | g++ is unable to compile code with nla_for_each_nested macro due to implicit type conversion from void* to nlattr*. This patch adds type casting for nla_for_each_nested macro to address this issue.

* lib/attr: add nla utility functions for signed integersThomas Haller2015-10-051-1/+41
| | | | | | | | | | | | | Commit 7bb956501ccd58ed3bbffc59de996f056e178683 added nla functions for s32. We preferibly add all signed integer operations at the same time. Thus, also add s8, s16, and s64. Also, previously the NLA_TYPE_MAX enum was not extended to have NLA_S32. Fix that too.

* lib: add const-ness to appropriate parameters in addr, attr, dataRohan Joyce2015-02-161-16/+18
| | | | | | | | | | | | | | | This patch changes the signatures of some functions to allow const pointers in places where a const qualified pointer is enough access for what the function does (e.g. nla_get_u8). It also changes some functions that take a pointer parameter and return a pointer derived from it to use the strchr idiom. This is not exhaustive in terms of places where const can be added, but it's a decent chunk that should not make the external api any more restrictive. http://lists.infradead.org/pipermail/libnl/2015-February/001826.html Signed-off-by: Rohan Joyce <rojoyce.github@gmail.com> Signed-off-by: Thomas Haller <thaller@redhat.com>
* attr: fix compile warning in headersPeter Wu2014-06-251-1/+1
| | | | | | | | | strlen() returns a size_t type, but nla_put accepts an int only. This breaks a -Werror build of applications using libnl, so avoid this warning by explicitly casting the length to an int.
